Carlos was very accommodating to my schedule, rearranging his so he could fit me in late in the same day. Very courteous, prompt, and professional. I got a mold testing for what seems to be a fair price. Would recommend.

we are new to the area and had the group at EBRR Cleanup do an evaluation on some mold under the bathroom sink. Before we followed through on the listing offer we wanted to make sure there was not a larger issue present. Ed was great and all the work happened within a week of our post, personable and friendly.

Val is the nicest. Came in, looked at what needed to be done, and gave me an estimate. I would say it was reasonable, as I have no idea how much mold remediation costs, but I can say "I was NOT crying all the way to the bank." The sub-contractors he had working with him were also very nice, friendly and personable. If you ever need to have mold removed, Val (and crew) is your guy.

These guys are as good as it gets, and I don't say that lightly... they removed the water from my entire basement within 2 days and they were able to dry it out without any mold growth.

The quality of work was very good. The original quote was for $199 to do mold abatement, but when they arrived, perhaps it was worse than anticipated because the actual bill for mold abatement was $399. The did recommend a piece of equipment, a UV light, for installation and charged $60 less than retail price, so Leo is a good guy.

From the moment they walked into my house for a FREE ESTIMATED which I loved to the last day they completed the project they showed professionalism, punctuality and work ethic. I love the way my whole house look after the mold inspection and removal plus the floor tile and mastic on my basement. I truly RECOMMEND CRISROD for any asbestos or mold project in your house or commercial.

This guys are the Achilles of water damage and fire damage, when the fire broke out fire department actually used allot of water to extinguish the fire, the floor simply looked dry but I was wrong , they brought in some kind of a moisture testing equipment and was about to detect all the moisture under the floor board, it was amazing, also my adjuster was giving me the run around, but they checkmated him in the most professional manners, I kind of like the knowledge that they displayed dealing with my adjuster, it was a delightful experience, I highly recommend them

Richard from American Home & Hardscape was extremely professional and responsive. He was very honest with me about pricing and level of effort, which I did not get from other companies I talked to. I hired them to re-do my back yard, and I was very happy with their work. It was a total transformation! His team was very professional and did a very good job keeping the area neat and cleaning up after the work was done. I highly recommend them!

Our experience with Mr. James and his team was very pleasant. All of the guys were very knowledgeable and professional. They handled all permits and inspections necessary to complete the project. We noticed an infestation of mold growth in one of our properties. We were already contemplating remodeling this area of the basement anyway. We decided to not only remediate the mold but also to hang new drywall throughout the entire basement, install about 13 recessed lights with smart motion switches, slate tile flooring, and rough in and install a full bath in the space. James came in and offered my husband and I a lot of different options to reach our desired goal beyond the mold remediation. He also did the bathroom design, and suggested some beautiful tile combinations and we loved them all. In short we decided to go with James to do the work and the project went flawless. Very professional, clean within reason during a renovation, and very organized and personable. He kept us informed at every stage and there were no surprises. They completed the project in about10 days including county inspections. James followed up with us a month after the job was completed to make sure that everything ok. Great customer service!! We will definitely be using Unlimited Resources in the near future and have recommended James and his team to several people already.

I spoke with Jennifer to set up my appointment. She patiently explained and answered all my questions. Got me all setup. The technician Russell was professional. I was very impressed with his knowledge on mold. I looked at the videos of my ducts I could see exactly what he was looking at. I found his honesty refreshing. I was going to add on a service and he said I didn't need it I could go with a less expensive choice. Wow. I was impressed start to finish. Highly recommend this company. Definitely will continue to use them.

Q & A

Answers to commonly asked questions from the experts on Thumbtack.

What is a mold remediation?

Mold remediation is the process of identifying and removing unhealthy levels of mold that have colonized in a home, office, school or other building. Over time, if untreated, mold can destroy a home by breaking down cellulose-based materials (like wood or ceiling tiles) and causing a slow and messy decay. In the shorter term, a mold infestation can cause severe health problems. According to the Federal Emergency Management Agency (FEMA), mold can trigger respiratory problems, nasal and sinus congestion, eye irritation, nose or throat irritation, skin irritations, problems with your nervous system, and aches and pains. Mold inspection and mold remediation are often requested in tandem, although they are two separate services. Nationally, mold inspection costs range from $250 to $300. If mold has been positively identified in your house, either by visual examination or through mold testing, remediation can safely remove it. Properly trained and equipped professionals use specialized equipment (like vacuums and air scrubbers with HEPA filters) to keep mold spores contained while they remove contaminated materials and treat infested areas with antimicrobial spray. A key component to a successful mold remediation after eliminating the mold is ensuring that the water source that caused the mold infestation is also resolved.

How does mold remediation work?

Mold remediation can eliminate mold colonies from your home or business. Mold is a normal part of daily life, but in wet or humid settings mold can quickly colonize and spread by making spores. Whether visible or hidden, untreated mold can cause real health problems and cause extensive (and expensive) damage to your property. Mold remediation involves killing the mold, removing the dead mold and preventing future mold growth. Here is an example of the steps involved in professional mold remediation:

  • Contain work area and apply negative air pressure HEPA air purifiers to prevent cross-contamination. If spores spread, the colonies can easily regrow elsewhere in your home.
  • Mist an EPA-registered antimicrobial to suspend and kill mold spores.
  • Remove affected building surfaces.
  • Bag and dispose of contaminated materials properly.
  • Treat cavities/underlayment and dehumidify.
  • Abrasively remove dead loose mold.
  • Apply EPA-registered protective sealer.
  • Perform clearance testing.

Remove containment materials.

How is a mold test done?

Mold testing can help identify a mold infestation in your home or business. Mold inspection costs can vary based on the type of test you want done and the number of samples you request. The national average mold inspection cost is $250-$300. The EPA explains that if you have a visible mold problem, in most cases sampling and testing is unnecessary. However, if you have unexplained and potential mold-related illness or can smell mold in your house, mold inspection costs may be a good investment. To avoid unscrupulous testers, the EPA recommends working with a testing agency that adheres to the analytical methods laid out by professional organizations such as the American Industrial Hygiene Association or the American Conference of Governmental Industrial Hygienists. Mold inspection costs can vary based on the type of testing done. Prices can also vary, depending on the size of the home, the number of surface areas to be tested, and the extent of the mold infestation. Here are some examples of mold inspection average costs:

  • Swab testing: $200-$300
    • A professional collects a surface swab from a potentially infested area for testing in a lab. Some professionals have concerns about this being the sole test done because it only gathers a small amount of data from a certain area of the house. That’s why it’s frequently done in conjunction with air cell testing.
  • Air cell testing: $250-$350
    • A professional collects an air sample in the home to measure the amount of mold spores in the air. This test is frequently done in conjunction with swab testing to ensure more complete data. Costs are higher for this test because the equipment required of the contractor is more expensive.
  • Both air cell and swab tests provided by the same company: $400-$600.

How do you get rid of mold?

Mold is a naturally occurring and important part of our ecosystem. That said, excessive mold can actually be hazardous to your health. Mold remediation is usually the best strategy to get rid of unhealthy levels of mold in your home or office. If you’re not comfortable working with mold or the area is larger than 10 square feet (3 feet by 3 feet), it is highly recommended to hire a mold remediation professional to resolve the problem. However, if you’re DIY-savvy, don’t have any health risks, and are not freaked out by mold, the EPA gives homeowners the greenlight to clean mold areas that are less than 10 square feet. Here are some EPA-recommended DIY cleaning tips:

  • Fix plumbing leaks and other water problems as soon as possible. Dry all items completely.
  • Scrub mold off hard surfaces with detergent and water, and dry completely.
  • Throw away absorbent or porous materials (like ceiling tiles and carpet) if they become moldy.
  • Avoid exposing yourself or others to mold.
  • Do not paint or caulk moldy surfaces. Clean up the mold and dry the surfaces before painting. Paint applied over moldy surfaces is likely to peel.
  • If you are unsure about how to clean an item (art, fine furniture, etc.) consult a reputable specialist affiliated with a professional organization in their field.

Is mold damage covered by insurance?

Mold damage may or may not be covered by your homeowner's insurance. Mold damage is caused by standing water and excess moisture. Mold damage can be covered by insurance when an item already covered under your homeowners insurance breaks accidentally — for example, if your plumbing suddenly ruptures and water floods your house, the homeowners insurance will cover part or all of the costs for the plumbing repair and any mold remediation costs necessary as a direct result of the water damage.

But you may not be able to get insurance to pay for your mold remediation costs if the damage is a result of your neglect — for example, if you’ve had a slow leak under your bathroom sink for years and have ignored the issue. If the insurer can determine that the mold damage is a result of your negligence, they likely won’t cover mold remediation costs. Also, most homeowners insurance will usually not cover mold remediation costs after a flood unless you have a special insurance rider covering your home in case of a flood. To help prevent mold damage, always keep humidity levels in your house between 30 percent and 60 percent, clean up water spills and damp areas right away, and ensure you have exhaust fans in your kitchen and bathroom.
