"I was lucky to come across this company on home advisor, Michael, Devon, and Shane exceeded my expectations. They were quick and professional. These guys treated mold and replaced the insulation in my new home, and went as far as removing all of the junk left by the previous owners. My crawl space looks like a completely different home within the week it took them to complete the job. I couldn't have asked for a better job, and I intend to mention them whenever I hear someone in need of work!"

"One of (if not the) best specialist we've worked with on a home purchase. David was extremely responsive and thoroughly answered every question we had from initial consultation through report result stages. He was super transparent in pricing and recommended testing, sent out samples and wrote up his report extremely quickly, and did a great job of explaining our testing results and recommendations. I felt I could trust David to properly test our property and that he would give us educated recommendations for remediation."

"AHS is ok. They cover repairs of most everything under the roof of your house. The companies that contract with them are not always the best. You call AHS with the issue, they send a fax to the repair company and give you the contact info. If they don't contact you within 24 hours, you call them. Sometimes they answer, sometimes they don't. When they arrive (usually three days or so later), they service the item. if it has issues within the 90 days, you call AHS again, they are sent out with no charge. If the serviceman decides the unit is unrepairable, AHS will allow you to choose a replacement from their listing (usually not as good as what you have) they will install and remove your old item, or give you wholesale amount to buy and install your own. Prices vary on what you want covered and what you want the copay to be, plus where you live. For me it is 49.99 per month with a 75.00 time of service order. You can have more than one item serviced at the same time under the same fee. If you have a SEAR product the repair guys are great. Not that wild about the other ones they send out. But it is a big savings compared to calling someone on your own. The cost of service is only the 75.00 copay."

Mold Testing and Remediation FAQs, answered by experts

Nearly all homes have at least some airborne mold spores. If you want to determine the concentration of spores in the air, you have a few options. The most effective option is to hire a professional tester who can take air samples of the home. The tester would send the samples to a laboratory to determine the concentration of mold spores. 

It is common for mold to grow around air vents, especially in areas with high humidity or moisture problems. These vents provide a perfect environment for mold to thrive due to the condensation caused by the meeting of warm and cool air. Mold growth can be accelerated by the presence of dust and debris around the vents. Regular maintenance, proper ventilation, and addressing any water leaks or excess humidity can prevent the growth of mold around air vents.

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.

Eliminating mold from wood permanently poses a challenge as the mold spores have the ability to deeply penetrate the porous wood surface. While surface mold can be effectively eradicated with proper cleaning and preventative measures, it's difficult to guarantee its non-recurrence under favorable conditions. To prevent mold from reappearing, it is important to identify and resolve the root cause of the moisture that triggered mold growth initially.

Ensuring appropriate ventilation and a dry environment, or consider applying protective finishes such as sealant, varnish, or paint to prevent future moisture penetration and mold growth. Consistently inspect and maintain the area to keep the wood free from mold in the long term.

When you smell something, it’s because the particles of what you are smelling are floating through the air. If you smell mold, it means that it’s airborne, and whether or not it’s harmful depends on the type of mold. It’s very hard to tell the difference between molds, even with the internet to guide you. Call a professional as soon as you see mold, they will test it, remove it, and make sure you aren’t breathing anything harmful.
