"We had a very good experience with SS John & Marin Restoration, who performed mold remediation on our basement. They were very thorough and experienced in their assessment of the situation, and worked with us to produce a custom estimate. They were timely in completion of the work. Sebastian was the manager for this project, who supervised the workers and communicated extensively with us to determine our needs. When the initially contracted work resulted in discovery of more moldy areas, the estimate was capped so that discovery of additional mold would not result in a higher cost. This company exemplifies care and motivation of customers, to implement recommendations that prevent future recurrence of mold in the home. For example, we implemented their mold prevention recommendations to run a dehumidifier and air purifier in the basement. Highly recommend this mold remediation pro."

"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."

"Steve calmed my fears and did the job in two phases at a great price. First all Mold was removed. Second Steve’s Cree came out and built the French Drain in my basement. In both occasions Steve’s crew came out on time and worked very hard to get the job done. Steve kept in constant contact with me during the process and sent pictures of the completed job. I highly recommend Steve for his professionalism and Honesty."

Mold Testing and Remediation FAQs, answered by experts

Mold can come back after cleaning, especially if the conditions are right. Mold loves moist environments, so if you clean a piece of furniture, then put it back in a humid area, the mold can return. Mold may also return if you missed an area during cleaning. A professional mold remediation company can help ensure that the mold is gone for good.

Musty smells often indicate the presence of mold, which can lead to various health risks. Inhalation of mold spores may trigger allergic reactions, causing sneezing, a runny or stuffy nose, and itchy or watery eyes. People who suffer from mold allergies or asthma may experience more severe respiratory problems. Certain types of mold, like black mold, can lead to mycotoxicosis, a condition associated with serious health effects like respiratory problems, fatigue, headaches, and skin irritation if exposure continues for an extended period. Those with weakened immune systems, respiratory problems, or allergies may be more vulnerable to the health risks that come with musty smells. Therefore, it is crucial to address and eliminate the source of the odor promptly.

Seeing black dots around the air vents is alarming, but don’t worry. It’s probably just a build-up of soot and darkened dust. Soot is just a byproduct of burning organic materials, so it tends to form in the winter months.

If you see mold spores on walls, flooring, or ceilings, it’s best to call in a mold inspection pro to investigate. Similarly, if you smell signs of mold—musty, earthy, rotting wood, or stale scents—it’s time to call a mold inspection professional. 

Other less-obvious times when you should have your home inspected for mold include:

  • After flooding

  • After home water damage

  • Having ceiling or wall damage

  • Buying or selling a home

  • After a persistent unexplained cough or allergy symptoms 

  • Noticing discolored surfaces

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.
