"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."

Mold Testing and Remediation FAQs, answered by experts

The easiest way to know if it’s a leak or evaporation that’s causing low water levels in your pool is by conducting the bucket test. However, you can also monitor the chemicals in your pool for signs of imbalances or conduct a visual inspection of the areas around your pool in search of excessive moisture or cracks.

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.

Yes, a one-time water leak can cause mold. Depending on the conditions, mold can begin to grow within 12 to 48 hours. The risk increases with the severity of the leak, high humidity, and when water soaks into absorbent materials like drywall. To prevent mold growth, stop the leak immediately and ensure the area is dried completely; running a blower fan for 24 hours is recommended. If you do notice mold, it's best to call a mold removal specialist to address the situation.

Painting over mold is not an effective solution and can actually make the problem worse. Instead, it traps moisture, which allows mold to grow and spread beneath the surface. Mold must be completely removed before painting to ensure the problem doesn’t recur. If mold is painted over, it may eventually seep through the new layer of paint, causing discoloration and peeling.

Common causes include water leaks, settling, and impact. Address underlying issues to prevent recurring damage.
