Attic Mold Removal in Lawrenceville, GA

What wets a Lawrenceville attic

Lawrenceville, the Gwinnett County seat about 27 miles from Atlanta, sits in the Yellow River watershed, and Gwinnett stormwater staff placed the heaviest rain of the September 2009 floods near the city, with parts of the watershed taking roughly 19 inches over eight days. Rain like that tests every roof seam, pipe boot and valley at once, and a slow drip that starts during a long soaking can stay hidden under insulation for months.

Most attic moisture, though, comes from inside the house. Many metro Atlanta homes park the air handler and ductwork in the attic, where summer heat builds fast and stays late into the evening. A clogged condensate line or a rusted overflow pan lets water spill onto the ceiling drywall, and uninsulated duct joints drip on the batts below. Bath fans that end in the attic instead of outdoors add a daily dose of warm, wet air under the roof deck.

Clean it or replace it?

EPA advises against painting or caulking over mold, so a coating sprayed onto damp wood is not a finished job.

Clues worth a closer look

• A brown ring on a bedroom or hallway ceiling below the attic
• Frost-like white or black speckles on the underside of the roof
• Insulation that looks flattened, clumped or darker in one area
• Rusty nail tips poking through the decking
• A musty odor when the pull-down stairs open

When to schedule it

Attic moisture problems tend to show up in two seasons here: late summer, when the AC runs hardest and condensate lines clog, and after a hard storm. Either is a good time to get someone up there while the source is easy to trace. If decking or rafters need replacing inside city limits, ask whether a permit is required by Lawrenceville Planning & Development, which takes applications through its online Licensing, Permits, and Plans portal. Georgia has no state mold license, so for any rebuild ask whether the company holds a Georgia residential or general contractor license and check it on GOALS Verify Now.
