The Crawl Space & Foundation Sub Charleston Contractors Rely On.

A crawl space sub who no-shows, cuts corners, or leaves a callback on your name can wreck a schedule and a client relationship. You need a crew that shows up when they say, does clean warrantied work, and communicates like a pro — so you can hand off the crawl space and keep building.

Lowcountry Crawlspaces is that crew — encapsulation, moisture control, drainage, and foundation repair, done in-house for GCs, builders, and remodelers across the Charleston area.

One Sub, Whole Crawl Space
Moisture, mold, drainage, structure

You don't have to line up separate vendors for encapsulation, drainage, and structural repair. We cover the entire crawl space with one crew and one point of contact.

What you get: one line item, one schedule, one number to call.

Contractor Questions — Straight Answers
Do you subcontract for GCs and builders?
Yes — a big part of our work is the crawl space and foundation piece for general contractors, custom builders, remodelers, and property managers. You bring the job, we handle the crawl space in-house and hand it back done.
Are you licensed, insured, and certified?
Yes. We're a licensed and insured Charleston County company with an IICRC-certified crew, and our work carries a lifetime foundation warranty and 25-year encapsulation warranty — documentation you can pass to your client.
Can you work around my schedule and other trades?
That's the point. We commit to dates and coordinate around your other trades so the crawl space doesn't become the bottleneck that holds up your build.
Do you handle the whole crawl space or just encapsulation?
The whole thing. Encapsulation, moisture control, mold removal, drainage, sump pumps, crawl space jacks, pier and structural repair, foundation work, and CL-100 clearance — all with one crew, so you're not lining up multiple subs.
How do I set up an ongoing sub relationship?
Call or email and we'll get you set up as a trade partner with a dedicated point of contact and priority scheduling on your jobs. Reach us at 843-259-8194 or LowcountryCrawlspaces@gmail.com.
