"Mold testing was thorough but do not let them sell you on their remediation do-it-yourself kit without knowing exactly what you are paying for. The kit is non-refundable and sold by a separate company. They do not tell you that. They transfer you to who you think is another employee to advise about remediation and they are actually transferring you to a completely different company. I was very disappointed when I learned all that. That company does not send out an itemized list of what you paid for unless you ask for it. It has been four days and after spending close to two thousand dollars I have yet to know what I bought."

"They did a wonderful job fixing up our foundation damage. And they have given us a 5-year warranty, which means if there's any leak in the next 5 years, they will come right back and fix it. I do not doubt that the work will hold up well though. The whole project went down smoothly, and we are very happy that they were able to fix our foundation."

"We had a plumbing leak in our ceiling and Art came out right away. He fixed the source of the leak, abated the mold, and repaired the part of the ceiling that had to be cut out. He textured and painted the ceiling so well that you could never tell any work had been done. He also patched and textured a few nail holes in an adjacent wall for free. On top of being great at his job, Art was fun to work with. Highly recommend!!"

"Cole was very polite, educated about ancestors procedures and disposal, and provided reference upon request. I Had my house tested for asbestos. He was able to visually inspect some areas to determine if they needed testing and saved my $$. The pricing was reasonable ($150 to come out, $35 per sample). The trading was done locally at a third party lab and I recieved my results before the week was over. some of the samples came back positive for asbestos, but I was not pressured to do abatement immediately. I did ask for a quote though."

"Rubin came out to look at the job and discussed an additional job I was considering. He did not send the estimate for the second job, but then did communicate the information to me when he came out to do the first job. Rubin was very professional, personable and a clear communicator. I had purchased and Angie Big Deal of three hours for $99 dollars expecting the job would require an additional 1-2 hours. His estimate and final price came out about what I expected. His work was very good. I will have him back to do the second job of refinishing the walls in the bathroom."

Mold Testing and Remediation FAQs, answered by experts

Mold can begin to grow in as little as 12 to 24 hours, especially if the room is warm, so drying the area is the first thing you should do after water damage. Because mold and mildew can cause a range of health issues, make sure you clean up any water damage as soon as possible and run blower fans and dehumidifiers for 24 to 72 hours to dry out the room and reduce the risk of mold growth.

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.

Mold grows quickly. It typically begins to grow on drywall about 24 hours after exposure to moisture or humidity. Drywall is a porous material, which makes it particularly hospitable to mold growth. 

While mold growth begins after just a day or so, it can take a few weeks before the evidence becomes visible. Mold spores will typically appear on the drywall surface within three weeks of growth starting.

A mold inspection costs an average of $660, with a typical range between $300 and $1,025. However, costs can be as low as $150 or as high as $2,800 depending on several factors. These include the size of your home, the type of mold, the extent and accessibility of the affected area, your location, and the number and type of samples required. Hard-to-reach areas like air ducts, crawl spaces, and wall cavities can increase the cost. Specific tests have different prices; for example, swab testing typically costs $200 to $300 per area, while more extensive air testing can range from $250 to $700. A thorough inspection is crucial for determining the scope of the problem and identifying the best remediation method.

Damp air from a humidifier can cause mold in ducts if it raises the air's humidity level too high for the duct system to handle or malfunctions, but it’s not a normal occurrence. To avoid mold trouble, set the humidistat to between 30% and 35% and inspect it often to ensure accuracy.
