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.

This company provided me exactly what I needed which was a repair of my siding rather than trying to sell me on a whole side replacement. They did the job quickly, professionally and matched my existing siding seamlessly which was 10 years old. They also cleaned up as they stated which is not always done by all companies. I would recommend this company to others.

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.

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.

I contracted MJ Home Services for a mold remediation, not only did they come out immediately after we entered an agreement. They also made me worry less on both the mold and financing by giving me financing option. I will recommend this company to people and will use them in other of my structures as need arises. Thank you MJ Home Services.

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.

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.

Brain was wonderful, professional, personable, knowledgeable and we would highly recommend him. We are first time homebuyers. We had a lot of questions as we were comparing different home inspectors and shopping around for a good deal. Not only was Brain patient with me he answered all of my questions to help me choose a home inspector. BB residential inspections were the most reasonable priced for a home inspection to include a radon test. The day of the home inspection, Brain was early. The inspection was approximately 2.5 hours long. Brain took the time to answer my husband questions, give practicable and reasonable approaches to rectifying the issues found. Within 24 hours we had the home inspection report and within 24 hours of the radon test inclusion we had the radon report. Brain, sent us great information to read in regards to radon. Brain also communicated well with our realtor, Kenneth Stewart, to explain information and schedule times to pick up the radon test results. We are so happy with Brain’s services.

My daughter had continuous headaches, and noise bleeds, New Beginnings, came out with in 24 hours of our call, they did not find any visible mold, or any service they could sell us, but after their visual inspection, they ruled out everything but our pet guinea pig. New Beginnings Restoration recommended us to use a hygienist, who discovered through testing that our pet guinea pig, was the cause of my daughter's illness. We give away her pet guinea pig, and my daughter's Health turned around with in a few days! Although New Beginnings did not make any money with us, our daughter is much much better due to their unselfish referral! This company has a lot of integrity, I would use them again!

The team at Restoration 1 was very professional and thorough in performing mold remediation and removal of water damage in our master bathroom. Cory explained the process clearly during the estimate and provided a very detailed list of work that would be done. Patrick and Darin worked hard the entire 10 hour day removing the water damage and mold. The price was fair and the work was complete very quickly. I hope we do not need Restoration 1's service in the future, but would not hesitate to call them again if we do.

Ansony was very professional. I hired ansony to check for mold and any air pollutant issues in the house as my family and I were having a lot of allergy issues at the recent house I purchased. He explained to us in very detail and clear what he found and how he could assist us with. He even answer a lot of question we had about other related issues in the house as well and provide us with possible solution ideas for those other issues. I highly recommend him.

I am so glad I chose Mold Removal Company! They are very professional and really do quality work. I am new to needing to address mold and they walked me through everything. Jake came out to do some testing first and was very thorough. He even came out on a Sunday for us so we didn’t need to take off work. He answered all of my questions and you could tel he took pride in his work. I received a copy of the lab results which also explained the findings in detail. Once we knew we needed to address some mold, it was so simply to schedule Todd to come out and do the remediation work. He was also very thorough and kind. He cleaned up everything completely. If I ever have to do this again (hopefully I won’t) I will definitely use Mold Removal Company again. (Photo is after mold treatment)

I used Oscar Rosales the owner pf Domestek for a mold remediation on my rental property. I found him to be very professional, responsive & punctual. He did a wonderful job in a timely manner that produced results that made my day at a cost that was budget friendly. I would hire Oscar again if needed and recommend him to others.

Q & A

Answers to commonly asked questions from the experts on Thumbtack.

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 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.

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.

Can mold grow behind drywall?

Mold can grow behind drywall, in your attic, in the basement, under floors — mold can grow anywhere. The key to controlling mold is controlling moisture and water. If your home has been exposed to excessive water due to flooding or heavy rains, if you have an old home with leaky pipes, or if you live in an area with high humidity, you need to be vigilant about mold. Mold is most easily identified by sight. You may see blooms of mold on furniture, on walls, or along the floor. If you can spot mold, you probably don’t need to test for it and can save on mold inspection costs and direct your energies towards mold remediation. But if you’re not certain, you may need a pro to help you determine whether you have hidden mold. Scent and illness are two potential signs of hidden mold. You may smell anything from a musty earth scent to a foul stench, and you may experience respiratory problems, nasal and sinus congestion, eye irritation, nose or throat irritation, skin irritation, problems with your nervous system, or aches and pains. The national average cost of mold inspection and testing is $250-$300.

How long does it take to get rid of mold in a house?

You can never completely remove mold from your house; a small number of mold spores will always exist indoors and are a natural and helpful part of our world. However, if water or moisture is left unchecked inside your home and mold begins to colonize, it can pose a serious health risk. Mold remediation can quickly and safely remove a mold infestation from your home or office. Depending on the size of your problem, mold remediation might take anywhere from one to seven days (or more) to wipe out the major sources of mold in your home.

Mold growths (colonies) can establish within 24-48 hours, so it is important to act immediately if you have a water spill or leak — especially if you live in a hot or humid climate. If you are past the point of DIY and need professional help, mold remediation teams will come to your location, assess the extent of the mold problem, identify and rectify all water leaks and sources of dampness, identify all mold sources (both visible and hidden), use specialized equipment to contain and prevent migration of mold spores, safely remove contaminated materials, treat infested areas with approved antimicrobial sprays, dehumidify and dry the appropriate areas, and seal areas as needed.
