Rated 4.9 by St. Louis-area neighbors
We had mold after a slow leak under the sink. They inspected it, explained the plan, and left the space dry and clean.
Our crawl space mold was worse than we thought. They handled the full remediation and installed a vapor barrier too.
Our process
Our mold after roof leak process in St. Louis, MO
Inspect
We check the attic, roof decking, and ceiling drywall to trace how far the water actually traveled.
Contain
We seal off the ceiling or attic access point before disturbing any mold-affected material.
Remove
Saturated insulation and mold-colonized drywall or decking are removed and bagged for disposal.
Dry
We dry the attic space and ceiling cavity fully, since trapped moisture in insulation dries slowly.
Verify
We confirm the space reads dry and treat remaining framing before closing out the job.

Good to know
Mold After Roof Leak in St. Louis, MO: common questions
How do I know if a ceiling stain has mold behind it?
A musty smell, a stain that keeps growing, or soft spongy drywall are signs mold may have developed behind a roof leak stain.
Can I wait until the roof is repaired to deal with mold?
It's better to have the moisture assessed as soon as you notice it. Waiting gives mold more time to spread through insulation and framing.
Does insurance cover mold from a roof leak?
It depends on your policy and the cause of the leak. We document the damage thoroughly, which helps if you file a claim.
Is the mold after roof leak you do in St. Louis to a real standard?
Yes. Our crew follows the IICRC S520 standard for mold remediation, the same framework insurers and inspectors recognize across City of Saint Louis.
Do you go into the attic to check for mold?
Yes, we inspect the attic space, insulation, and roof decking since that's usually where roof leak moisture starts before it reaches the ceiling.
Will you replace my insulation?
We remove and dispose of insulation that's saturated or mold-affected as part of remediation. Reinsulating is typically handled alongside your roof repair.
Will my insurance cover mold after roof leak in St. Louis?
It depends on the cause. When the mold follows a sudden, covered event, there is often coverage. We bill your carrier directly and document the loss so your St. Louis claim moves.
