Learn more about Interior & Exterior PaintingMost homeowners never see their crawlspace. We crawl it, photograph it, and explain it in plain English before anything gets priced.

You see the mold, the standing water, or the crushed duct for yourself, and the finished work afterward.
Encapsulation, mold, drainage, and framing under the house are what we do day in and day out.
Scope and price on paper before work starts, so there are no surprises on the invoice.
Mold and rot come back if the moisture stays. Every job includes a plan to keep the space dry.
Crawlspace, ducts, dryer vents, insulation, and interior repairs, without juggling contractors.
A Durham-based, locally owned company serving the Triangle and Central North Carolina.
Four steps, and you know what's happening at each one.
Tell us what you're noticing: musty smells, water, soft floors, high bills. We set a weekday visit.
We crawl the space, take moisture readings and photos, and walk you through what we found.
A clear scope and price for the fix, including what's causing the problem.
We do the job and send before-and-after photos so you can see the result.
Photos straight from our jobs: crawlspaces before and after encapsulation, and ductwork before and after cleaning.
