"They responded very quickly and sounded very knowledgeable. The test results were sent the following day. This is a minor thing but the inspector talked in technical terms which I did not understand. I wish he could have explained more. However, on the report I received all the technical terms were clearly defined in a way I could understand. A suggestion would be to provide the customer with the explanation of thes terms at the time if the inspection or talk to the customer in terms they can understand."

"Quacker's Waterproofing was wonderful. When they came for the estimate, they were fast and no nonsense. They weren't trying to convince me of things that needed doing or dramatizing the work for more money. When I had questions about the work, they didn't make me feel dumb but took extra time out of their day so that I had peace of mind with my foundation. I hope to never need their help again, but I will definitely call them if I do. Special kudos to Rob!"

"The guy was really helpful but I couldn't afford what he charged me at that time. Otherwise I thought that they are a pretty good company. The guy who came out was really informative and helpful. As a matter of fact we had sewer damage and he had suggested about to claim with the metropolitan sewer industry. He was really pretty knowledgeable and very professional. The estimate was for around $4500 to $5000. It would have been well worth it but I couldn't afford it at that time. I think he was excellent personally. He was here when he said he would be here."

Mold Testing and Remediation FAQs, answered by experts

Having a dry house can be unhealthy for you and the home. Excessive dryness can lead to respiratory issues, dry skin, dry or sore throats, and other problems. Additionally, any wooden furniture and the home's structure and floors can suffer from cracking and shrinking under dry indoor air conditions, leading to gaps and splits.

Thorough inspection, air quality tests, and surface sampling to detect mold presence and levels.

Mold doesn’t take long to form, especially in dark, isolated areas like under the floorboards, where you’re less likely to know it’s wet in the first place. Mold can take root and proliferate in just 24 to 48 hours, but it can be up to a week before you start to notice funky smells. 

Mold inspections are worth it because they can catch troublesome mold problems early before they get out of hand. It's worth it to address mold problems as soon as possible because mold can be hazardous to your health and cause damage to your home and its belongings. Mold testing and inspections are the best way to know if you have a mold issue in your house.

Yes, both mold and mildew can grow under outdoor rugs if they are exposed to water or humidity for a prolonged period of time. This is why frequently cleaning an outdoor rug and checking its state is important.
