Why Your Greenville Crawlspace Needs a Real Look

A lot of Greenville homes were built on slopes, which means water finds its way under the house whether you want it to or not. We see it across the whole city — high humidity readings, warped floors, the musty smell that shows up in the closets first. If any of that sounds familiar, we’ll come take a look for free and show you exactly what’s going on down there.

In older Greenville neighborhoods — Overbrook, Cleveland Park, North Main, the bungalows off Pettigru — we’re usually dealing with crumbling vapor barriers from the 90s, open foundation vents, and dehumidifiers that were either undersized or never installed at all. Those are straight-forward fixes and we’ll quote you on the spot.

Out in Five Forks, Woodruff Road, and the newer subdivisions around Simpsonville and Mauldin, the issues are different — tight builds with poor ventilation, HVAC pulling air from the crawlspace, moisture getting trapped. We handle both sides of Greenville and we tailor the solution to the house, not the sales pitch.

Neighborhoods we work in: North Main, Augusta Road, Cleveland Park, Overbrook, Five Forks, Woodruff Road, and surrounding communities.
