I needed them to expand their scope to fix the whole problem, not just the symptom of mold. They were great to work with and got the job done.

Jose was great... He makes it a great experience for you (You'll forget you're testing for mold!). He also was really sweet to my toddler who was fascinated by the process.

I cannot speak high enough about Alex and Oxi Fresh East Bay. Alex called me to walk me through the process; I had to change my request several times as new information came up and Alex was as flexible as possible. The job was to clean a sentimental old couch that was severely damaged by water and mold. Oxi Fresh came in and tried a few techniques to see what would work. They refused to charge me until they knew what would be successful. When they came back to finish the job, they were timely, effective and very personable. I will be using Oxi Fresh East Bay as go to cleaners.

We are home-buyers and were invited to do our own home inspection while we waited for the appraisal and underwriting to come in. My father-in-law insisted that we do a mold inspection, so my husband contacted Tincher Inspection Services to do it. I was present at the inspection, and really enjoyed going through the house with Monty Tincher. Monty arrived early, ready to go. He started by taking air samples and has an infrared scanner that allowed him to look for moisture and heat differences in the walls. He flushed the toilets and ran the showers looking for leaks. He was able to look into a wall where there was an active drywood termite infestation to determine how far up they currently were (the termite activity generates heat). He took a look at some of the issues that the seller's inspector had found and gave us his opinion on them. He had no problems with me coming through the house with him, and invited me to come into the attic to take a look and under the house as well! We discussed solutions to some of the issues with the house and he gave me rough price estimates for fixing them which was very helpful. I highly recommend Monty for your inspection!

Eddie removed a window frame full of dry-rot and replaced it. He did a great job at a fair price. He even took the time to describe the process and the choice of materials. I would recommend him in a heartbeat.

Great customer service!! I called them this past Thursday to make sure I got quoted the correct price because other companies charge double just for testing. It was correct and someone came out to do the test the next day. Joe was very polite and professional. Still waiting on the test results because this took place this past Friday and Monday was a holiday. I would recommend them to anyone that's dealing with a mold issue

Extremely happy with the service Chris provided. I suspected mold in the home I just rented and the landlord was not cooperating with me. Chris made the time to not only come out urgently, but he performed an important test then rushed results, helping me a lot. Great service, this is your guy.

My house suffered extensive water damage and mold from internal flood. Insurance hired a restoration company on my behalf but it did as little as possible to the benefit of insurance company. Not happy with drag out and incomplete tear out works, I hired Professional House Repair Restoration company to complete the tear out and mold remediation works. Denis, the job PM, was on time with the appointment, very knowledgeable, patiently listened to all my concerns. Denis not only answered all my questions but offers relevant tips and ideas on prevention. He explained in details what will be done, how it will be done and why. Then he and his team just did them. Their works were very thorough and well done. I am very happy with the results. Denis was very professional throughout (from estimate visit to post-work-walk-through inspection and reports. There were several small additional work I requested, and Denis promptly took care of them. Denis even spent extra time to prepare separate itemized detail invoice for me to submit to insurance company for reclaim. The reports that Denis prepared is excellent. It has before & after photos with details on what were done. I feel very comfortable of the house readiness for follow-on reparation works after Denis and team completed the works. Kamil was very responsive to all my phone calls and text messages at all kind of hours. I am impressed with Kamil customer services. He was a very good listener and followed up on all request for information and status. Kamil was very flexible and accommodating on contract terms. I highly recommend PHRR for restoration and mold remediation works.

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.
