Finding mold in your home can be a stressful situation. It can be hard to know how prevalent the mold is, whether it has spread, if it's harmful to you or your family, or how to proceed with mold removal services and clean up.

Luckily, Marin County and the Greater Bay Area has a number of licensed, insured, skilled mold removal and repair companies that excel at removing mold from homes and businesses.

Research is your best weapon against mold and in finding the right local mold removal company to help you. Finding the best mold removal services in San Rafael, San Anselmo, Novato, Mill Valley and Larkspur and the rest of Marin County is much simpler when you have the facts about mold and know what to look for in a good contractor.

The articles below will give you the information you need in order to make an educated decision on the best path to take when it comes to hiring a mold removal company.

The Dangers of Mold in Your Home or Business
Mold, mildew and other fungi aren't just ugly. They can also cause illness and even, in extreme circumstances, death. The dangers of toxic black mold have been widely discussed, but even less toxic types of mold and mildew can cause illness and frustration.

Your safety and that of your family are of the utmost importance, and you should feel safe in your home. Whether you can see it or not, the presence of mold in your home can cause any of the following signs and symptoms:

  • headache
  • fatigue
  • weakness
  • muscle stiffness and joint pain
  • poor memory and difficulty concentrating
  • shortness of breath
  • chronic coughing and wheezing
  • skin rashes
  • sinusitis and sinus congestion
  • tingling and numbness in the skin and limbs
  • abdominal pain
  • vertigo
  • lightheadedness
  • red eyes, watery eyes and blurred vision
  • trouble regulating body temperature
  • loss of appetite or appetite swings
  • flu-like symptoms
  • metallic taste in the mouth

When Should You Hire a Mold Remediation Company?
Some types of mildew and mold are easy to remove, and you can do it yourself. Other types, such as black mold, require professional removal and remediation services in Ross, Belvedere, Corte Madera, Tiburon, Sausalito and Fairfax and beyond to remedy the problem.

Buildings, including homes and office buildings, that are hosts to mold often have experienced one or more of the following causes or symptoms:

  • past flooding or water damage
  • leaking pipes or a leaky roof
  • musty smells or a strange odor
  • consistently damp or wet areas, including basements, attics and crawlspaces
  • the presence of visible mold or mildew (remember: not all mold is visible or in areas where it can be easily seen)

If your home or business, currently or in the past, has any of the above warning signs, and you and your family or co-workers are experiencing signs of mold exposure, call a professional mold contractor. They should be able to perform mold testing to confirm the presence of mold. Then you'll know if mold removal services are needed.

Can I Do It Myself?
When you know it is present, it may be tempting to try to remove mold yourself. But there is a very important fact about mold to remember: it spreads through scattered spores. Unfortunately, that means that well-meaning homeowners who try to remove mold on their own can, instead, spread the spores and multiply the problem all over their home.

While some types of mold are easy to remove (such as typical bathroom mildew that can be removed with commercial mold removers available at stores), mold that is in walls or home materials and, especially, toxic black mold and other harmful types of mold must be removed by a professional to ensure your safety and the complete removal of the danger.

Hire Diamond Certified Mold Removal and Abatement Services in Marin County
Your best option is to hire a Diamond Certified mold contractor in Fairfax, Tiburon, San Rafael, San Anselmo, Novato, Mill Valley and Larkspur or your area of Marin County. That's because Diamond Certified companies are rated Highest in Quality. They've been carefully vetted through checks of license and insurance, actual customer references and more.

If you’re unable to choose a Diamond Certified mold removal contractor in your area, you can improve your chances of hiring a good company by checking out candidates on the Contractors State License Board website to ensure active license and workers’ compensation insurance. Violations will also appear on their license record, so you’ll know about recent infractions or serious customer grievances that have been processed by the state.

Then take time to verify company credentials. Marin County mold removal services that are members of local remodeling and home addition organizations and national building associations may offer better service, and you’ll be able to see their past records, including complaints and legal action.

As with any working relationship, it’s important you work well together. So you’ll want to consider the personal and professional qualities you value in a mold removal and repair contractor. Promptness, good communication skills, honesty and cleanliness are important, so decide what traits you want in the contractor you hire and don’t settle for less.

As you're doing your research, keep in mind that references provided to you by Marin County mold removal companies are not equal in value to the large random sample of customers surveyed during the Diamond Certified ratings process.

If you do call references on your own, specifically ask for a list of the mold removal company’s 10 most recent customers. This will help avoid them giving you the names of only customers they know were satisfied. Then, make some reference calls and ask these questions and others.

  1. Were you satisfied with the mold remediation work from _(Marin County mold removal company name)_?

  9. Did the workers show up on time?
  10. Did they clean up and leave your home or business in good condition after the mold removal and repairs?
  11. If you need mold removal work in the future, would you use this contractor again?
  12. Would you recommend this company to friends or family?
  13. Is there anything you wish you would have known before hiring this Marin County mold removal company or began the mold remediation work?

How to Work With
Signing a Contract that Will Protect You During the Mold Removal Process

You've carefully vetted and interviewed mold removal companies in Novato, Mill Valley, San Rafael, San Anselmo, Larkspur and Corte Madera and near you. Now you should have a good idea of which mold mitigation service can best meet your needs in both a professional and personal capacity.

You've carefully vetted and interviewed mold removal companies in Novato, Mill Valley, San Rafael, San Anselmo, Larkspur and Corte Madera and near you. Now you should have a good idea of which mold mitigation service can best meet your needs in both a professional and personal capacity.

Now is the time to move forward by signing a contract for the services your home needs.

Be sure you've had mold testing done by a third party to confirm the presence of mold and the type of mold present. This is important, as it will inform the way the mold removal company performs their services and testing after the mold removal will prove that it has been completely excised from your home and property.

Once you know the type and scope of work to be completed, sign a detailed contract that represents your interests and protects you and your mold contractor. Good contracts should include the price (itemized amounts for materials and labor are best), scope of the work, start and end dates, and any requests or details of the work that you’ve agreed upon with your local home mold removal contractor. You’ll also want to confirm any warranties or guarantees at this time and make sure they’re in writing and present in the contract.

You can write in any special requests or verbal agreements to ensure that they are part of the written record and reflected in the final outcome.

Read through the contract and work order and be sure you understand all terms and limitations before you sign. Contracts are legally binding, so for your protection, never sign a blank or incomplete estimate, or one with which you disagree.

Then, schedule a date and time for the services and get ready for your mold removal and repair services.

Get Ready for Successful Home Mold Removal Services
Before your mold mitigation work begins, you should think about ways to simplify the job. Not only can this make your life easier, but it can cut down on the amount of frustration and billable hours for the job. This can save you money and stress during the work.

Know if you can stay in your home during the work. Depending on the size and scope of the work, and the type of mold present, you may or may not be able to remain in your home during the mold removal work. If your contractor recommends temporarily moving out of your home during the mold removal, make arrangements to stay elsewhere. This can be more comfortable for you so that you don't have to worry about negotiating around mold removal technicians and the area where the mold is being removed.

Provide storage space. Mold removal and repair services in Marin County may need room to store mold removal equipment, mold repair materials and more. Find out if your mold abatement company needs room to store items, and then provide easily-accessible storage room where possible.

Supply access and clearance for work trucks and employees. During the work, your mold removal service will likely need to have oversized work vehicles on the premises. They'll also need access for their employees. This may include finding room for parking in the driveway or on the street near your home. Ask how many work trucks and how much room will be needed so you don't have to worry about parking on the day of their arrival. If you live in San Rafael, Novato, Mill Valley, San Anselmo, Larkspur, Corte Madera, Tiburon, Sausalito, Fairfax, Ross and Belvedere, Sleepy Hollow, San Geronimo, Marshall, Marinwood, Lagunitas, Forest Knolls, Greenbrae, Terra Linda, Woodacre, Muir Woods, Point Reyes Station, Strawberry Point or other areas, you may want to find out if your local jurisdiction has rules about parking oversized vehicles on city streets. Provide access codes, extra keys, or be around to let in employees during the work.

Move items from the areas to be treated for mold. Ask if you should remove furniture, decorations, rugs, stored items and other materials from the rooms where the mold abatement will be taking place. This will protect your belongings and make it easier for your mold contractor to access the affected areas. You should remember, however, that mold spores spread mold, so it's important you talk with your mold removal company about which materials should be moved and which need to be treated to prevent the mold from returning.

Stay out of the work area. It can be tempting to check in on the progress of the job, but interrupting your Marin County mold abatement contractors while they're working can be dangerous for you and for them, and it can slow down the job. Likewise, be sure to keep children and pets away from the work areas and areas where employees will be walking to and from the job. Even during off-hours, work sites can be filled with dangerous tools and equipment and mold can be exposed. Stay away from work areas and areas that have been cordoned off for your safety and the success of the job.

The most popular mold removal and repair services in Ross, Belvedere, Corte Madera, Tiburon, Sausalito and Fairfax and throughout Marin County include the following:

Marin County Mold Inspections
Also known as mold testing, mold inspection is a common service provided by Marin County mold removal companies. Mold inspections may be visual inspections, in which the mold contractor does a physical inspection to see where mold is located and the extent of the mold problem. This may include moving or removing walls and other barriers to better see the area. Mold inspections can also be performed using air and surface testing methods and technology. This ensures that mold spores have all been removed from the area so that the mold doesn't return. Keep in mind that it's best to hire a third-party mold inspecting company before and after the mold removal to determine which type of mold is present and whether it has been completely removed.

Mold Abatement
Mold abatement is another term for mold removal and mold remediation. It's the removal of mold from homes, businesses, schools, commercial buildings, apartment buildings and other buildings.

Mold Damage Repairs in Marin County
Once mold has been removed, homes and commercial buildings may require mold damage repairs. Contractors in Marin County that specialize in mold damage repairs, including those serving areas such as Novato, Mill Valley, San Rafael, San Anselmo, Larkspur and Corte Madera and beyond, are often skilled at insulation replacement, drywall repairs, wall repairs, plaster refinishing, cabinet repairs, exterior repairs and more.

Black Mold Removal
Some companies specialize in the removal of black mold and other toxic mold removal services. Toxic black mold, also known as Stachybotrys chartarum, produces mycotoxins that can make humans very ill. It is known to grow and spread easily in homes, especially in basements, attics, insulation, bathrooms, under cabinets, and in other dark and damp areas. Black mold removal must be done by a certified and qualified mold removal contractor who has the right tools for the job to prevent it from spreading throughout the house.

Mildew Removal Services
Mildew is a very common type of mold that is most often found in bathrooms, basements and other damp areas. It can be powdery or downy, white, yellow, brown, green or, most commonly, black. Mildew can usually be removed with a combination of sprays and wet removal methods, and by removing drywall, wood, insulation and other affected materials. Most mold removal companies in Marin County can provide mildew removal services and mildew abatement.

Bathroom Mold Removal Services
Bathrooms are common breeding grounds for mold and mildew because they are frequently damp. Wet, damp, and moist areas are favorite areas for mold growth. Bathrooms can see various types of mold growth, including mildew, black mold, mold under cabinets, in flooring, mold on walls, and mold in areas where water seepage occurs. Bathroom mold removal should also be followed by mold prevention strategies to prevent leaking and seeping water, and to remove the possibility of mold growing again in the same locations.

Removing Mold From Walls
Mold can grow in and on walls, particularly those that have been inundated with water or are in rooms or areas that are frequently wet or damp. Mold removal from walls usually includes hiring a company that can open up walls to remove any drywall, insulation, backing board, and other fibers and materials that have become infected with mold spores. Removing mold from the surface of the walls will only treat the surface of the problem. Underlying mold issues need to be torn out to keep it from returning or from becoming worse.

Commercial Mold Removal Services
Commercial mold removal companies work in commercial, public, civic and other large buildings to prevent and remove mold growth. These services often specialize in industrial spaces, multi-family units and apartment buildings, commercial buildings such as businesses and stores, and large-scale facilities and civic buildings such as governmental buildings and schools.

Mold Removal from Homes
Residential mold removal services in Marin County, including those in Fairfax, Tiburon, San Rafael, San Anselmo, Novato, Mill Valley and Larkspur and other areas, have the tools and expertise to remove mold from homes. This can include basement mold problems, kitchen and bathroom mold growth, mold in crawlspaces and attics, toxic black mold removal, mildew removal services, mold mitigation, sterile mold removal and mold testing services.

Basement Mold Removal in Marin County
Like bathrooms, basements can be prime ground for the proliferation of mold. Damp, dark conditions can encourage fast growth of white mold, toxic black mold, mildew, and other forms of mold. Basement mold removal includes pre-removal mold testing, removing visible mold, treating for mold spores and invisible mold, removal of any tainted materials, and post-removal mold testing services (preferably by a third-party service).

Heading off problems before they begin by hiring good mold removal companies with good records of providing quality service and satisfying clients, and that guarantee their work. There are many in San Rafael, Novato, Mill Valley, San Anselmo, Larkspur, Corte Madera, Tiburon, Sausalito, Fairfax, Ross and Belvedere and throughout Marin County that can meet these requirements.

However, even good companies can have bad days. If you do have a disagreement or problem with your Marin County mold remediation service, you should know what to do to end the conflict and get the work back on track.

  • Meet in person with your mold repair contractor immediately when you have a complaint or a concern with the details of the job, the crew, materials, methods or service. Don’t wait until the job is done to bring up your concerns.
  • Revisit your contract with your mold removal contractor and try to verbally resolve the problem.
  • Write down your complaint and, if possible, photograph the work or materials you’re concerned about.
  • Document the times you contacted your Marin County mold removal contractor and their response to your complaints.
  • Set a deadline with your contractor for resolution of your complaints so the disagreement doesn't drag on for a long time.
  • If you don't get an appropriate response from your contractor, consider calling a local building inspector or a third-party mold expert to neutrally evaluate the problem.
  • You may legally withhold payment until the dispute is resolved.
  • File serious grievances with the Contractors State License Board.
  • Contact your state attorney general if you are considering pressing charges against the Marin County mold remediation contractor for serious violations or dangerous conditions.
  • Fire the contractor as a last resort. Releasing the mold removal company from the contract can result in lengthy project delays and costly lawsuits.

Also known as: allergen, allergenic mold

allergenic mold
Allergenic molds are types of mold that cause allergic symptoms in individuals who have sensitivity to that type of mold.

containment
Mold removal companies often use containment methods to prevent mold spores from moving throughout the home or business during removal. Common types of containment include barriers, seals, air-locks, negative air filtration systems, plastic sheeting, HEPA filters, and other methods to control and prevent movement of airborne mold spores. This can prevent secondary contamination and the spread of mold.

Also known as: containment barrier, mold containment system, mold spore containment

Also known as: HEPA filters, HEPA, HEPA mold filters

hidden mold
Mold that grows in areas that aren't easily accessible or seen is known as hidden mold. This type of mold can be found in walls and insulation, under carpeting and carpet padding, behind cabinets or shelves, between the rafters and the ceiling, in crawlspaces and attics, above drop ceilings, in HVAC ducts or venting, and other areas not easily visible. Hidden mold is dangerous because residents may not know it is present, and may not realize it is the cause of allergic response, illness or other health problems. Mold removal companies should be able to find hidden mold using mold testing services and by moving or removing materials that may be impacted.

Also known as: invisible mold, unseen mold, mold behind walls, mold under carpeting, mold behind cabinets, mold in HVAC system, mold in insulation, mold in attic, mold in ceiling

microbes

Also known as: mycotoxins, microbes, allergic response to mold

remediation
Mold remediation is the act of removing mold from homes and other buildings and repairing any damage caused by the mold or the removal of the mold.

Q: What is mold remediation, removal and repair?
A: Mold remediation is the process of removing and cleaning up mold and mildew from homes and businesses. Homes or businesses that contain large amounts of mold or serious mold problems can benefit from mold removal and repair services, which remove the mold, treat the area to prevent mold from growing again, and repairing any damage resulting from the mold or the removal of mold and mold-tainted materials. Mold remediation contractors often use specialized materials, equipment and methods to completely remove mold from structures.

Q: How does mold become a problem?
A: Mold enters homes, businesses and other structures as small spores, which are usually airborne. Mold spores that are exposed to the proper physical circumstances can begin to grow and destroy the area around them. Mold requires moisture to grow, and most types of mold spores like darkness. Mold can grow in wood, sheet rock, insulation, carpeting, ceiling tiles, behind or on wallpaper, roofing, attics, crawlspaces and other areas and on other materials. Keeping your home dry is the best way to avoid mold contamination.

Q: How long will mold removal services take?
A: That depends on the type, severity and location of your mold. Most mold remediation services can take care of most mold problems in one to five days. Call your local mold removal and repair service for details on your specific mold problems, type and location.

Q: Are mold and mildew different?
A: Yes. Mold and mildew are different types of fungus with different colors, textures and levels of hazard. Mildew is more common than mold, and it often exists in small quantities in homes (particularly in bathrooms and under sinks or other damp areas). Mildew, while ugly and annoying, is rarely dangerous or toxix.

Q: What does mold look like? Can I determine if it's dangerous by its appearance?
A: Mold comes in many varieties, all of which look slightly different and grow in various locations. Mold can range from light green to dark black, and usually prefers damp, dark locations. Some types of mold even have a distinct odor. If you think you have mold in your home, you should call a mold removal company or industrial hygienist to determine whether the material is indeed mold, and whether it is dangerous. They can advise you on removal methods, independent testing, searching for hidden mold locations and other services that may be needed.

Q: Is mold removal and remediation expensive?
A: The cost of mold removal services depend on the location, type, severity and other details of your mold problem. Repairs and other services may also be required. Mold removal can be very costly, and the expense only grows over time as the mold problem gets worse, so it is smart to have any mold taken care of immediately. Insurance may cover mold removal costs. Remember, the best mold remediation services are rarely the cheapest ones. Don't use a budget company that has inferior removal techniques to save money. You may find in the long run that it is more expensive to have to hire a second company to complete the work. Instead, hire a licensed, insured, qualified company to provide guaranteed mold removal services that will protect you, your home and your family.

Q: Can I perform mold removal myself?
A: That depends on the type, location and severity of the mold problem, your skills, the materials and equipment you have available to you, and your ability to completely remove the mold in a safe manner. The biggest problem with mold removal is the fact that when you disturb mold by cleaning it, cutting it out, or otherwise attempting to remove it, you release mold spores that can be spread throughout the home or business, and which can create new mold problems in other areas. Thus, it's important to know what you are doing when removing mold or you can make the problem worse. Properly containing mold spores and completely removing them is the only way to perform proper mold remediation and removal services. You will also need the right protection equipment to prevent yourself and other individuals active in the removal from becoming sick from contact with mold spores. If you're not able to meet these standards, it's best to hire a professional mold removal or mold remediation company to take care of the problem for you.

Q: How do I know the mold is completely removed?
A: You should be able to perform a visual inspection to see that the mold is gone. However, hidden mold and mold spores can be hard or impossible to see. To completely verify that mold has been removed, you should have third-party mold testing performed. Your mold contractor should not perform this testing, as it is a potential conflict of interest. Instead, they should rely on a separate service for testing both before and after the mold removal services. Additionally, be sure that the mold removal testing service uses independent tests that are delivered in writing and will stand up in a court of law if you ever have to go that route.

Q: Is mold dangerous?
A: Some types of mold are simply ugly. Other types of mold can be toxic. It's not uncommon for the presence of mold to cause headaches, dizziness, allergies and allergic-type responses, coughing and wheezing, rashes, asthma, nasal stuffiness, throat irritation, lung infections and even, in extreme circumstances, death. Black mold is one of the most common culprits for reactions from sinusitis to death. That's because black mold and other types of mold release mycotoxins that can make you very ill. Have your home tested for mold by an independent, third-party testing company and then hire a qualified, certified, licensed and insured mold remediation company to take care of the problem if you find mold in your home or business.
