"Jeremiah came out and tested the air and moisture and other items to determine if I had mold in my basement. After getting the test results there was evidence of mold and he recommended a company that provides a do it yourself kit for mold remediation. (Not cheap). After getting the items and realizing that there was more work, it would have been better for me to let my insurance company handle this as I do have coverage for mold/fungi. Though having a professional do the work is expensive, from what Jeremiah mentioned, it does not guarantee that the work will be complete or the source of the problem taken care of. He mentioned most companies will take care of the mold but not necessarily the cause of the mold. For this I would have to contact another company."

"Mark and helper climbed their ladder outside to the Soffit under the roof overhanging. They cleaned the vent and ran a brush all the way down to the clothes dryer. Now my clothes are dry and the amount of dust has increased due to the opened pathway. Any dust that came outside was cleaned up. Great job. Thanks!"

"This was the 3rd time we have used Lawson and we have been very pleased each time. The first was a crawl space, the second was to remove old insulation in the attic and replace it. This time we had Lawson install a vent from a bathroom fan and install a Sanadry unit in our basement. No more moisture or musty smell! Great job every time and the men are pleasant to work with and respectful of our home. Neat and tidy work."

"After coming home from a vacation and finding our finished basement flooded we used Home Advisor to find help. CARE Property Services responded immediately and did a thorough job of removing the water, and drying out the basement, after removing all furniture and multiple cardboard boxes. After the dry out they returned for the recovery phase, replacing drywall and insulation as needed, painting all rooms and a thorough cleaning of the carpet. Then they put back all the furniture and those boxes not ruined or that we requested to leave for us to evaluate. They worked with our insurance company making the entire process as easy as possible. They were wonderful to work with, professional, helpful and did all they could to prevent any disruption to our life. I highly recommend them."

"I called Rytech because I thought I might have mold in my house after a pipe busted. I thought we had dried it pretty good but apparently not. They came in a were able to explain to me clearly what the damage was and what to expect. The guy they sent out was very knowledgeable, professional, and efficient. I would definitely use them again and recommend them to anyone who thinks they might have a mild problem"

Mold Testing and Remediation FAQs, answered by experts

One of the first signs of mold in an air conditioner is a musty smell. You're likely to notice the smell when the unit runs, from the air coming out of the vents or the unit itself. You may also be able to see mold growing on the unit, such as near the condenser coils or by the fan. In some cases, there may be visible mold by the vents.

Water damage occurs when your property or items suffer damage due to excess and unwanted water or moisture. The water could be present due to a natural disaster such as a hurricane or a burst pipe—water damage can be caused by many things. If necessary, contact a local water damage restoration company.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly—ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.

Yes, mold can grow in a wet dryer vent. Mold is a type of fungi, and fungi thrive in warm, moist conditions. Dryer vents need to be aired out so heat can escape and moisture can dry. If your dryer vents aren’t properly vented, the trapped heat and moisture will cause mold to grow, and the mold can spread to the dryer and even your clothes. Not only can this leave a musty smell on your freshly laundered clothes, but—more importantly—it also poses a health risk.

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.
