Most of what makes a house feel solid underfoot is happening in a space you have probably never been in. When floors start to bounce, slope, or dip, the cause is almost always under them.
JTB Construction handles residential crawlspace encapsulation and repairs across the Charleston area, addressing moisture and pest damage and stabilizing the structural system that carries your home. If something is happening beneath your floors, we would be glad to get under there and tell you what we find.
The space under your floor holds up everything above it. Our crawlspace construction work covers the full structural system:
The goal is level floors, tight framing, and a structure you can stop thinking about.
Humidity is a fact of life in this part of South Carolina, and it works against wood framing every day. Our approach to crawlspace construction accounts for that from the start, using materials suited to a damp environment and paying attention to how air and water move through the space.
Vapor barriers and crawlspace encapsulation work are part of that. A properly installed vapor barrier across the ground and up the walls keeps ground moisture from rising into your framing, and full encapsulation seals the space so the floor system stays drier and steadier through the seasons. Moisture management systems are put in place, and joists and beams last a lot longer in a crawl space that is not feeding moisture back into them.
JTB Construction is a veteran-owned company with more than 10 years in business and over 500 completed residential projects across the region. We are a licensed South Carolina residential builder (RBB 50612) and fully insured.
Crawlspaces don’t make for comfortable work, and it is easy to cut corners when no one is going to look. At JTB, we ensure the job is done right, even if that means taking the extra time to address an unexpected issue before considering a project done. We bring the same standard to a crawl space that we bring to a finished room.
Integrity and service are at the heart of everything we do.

The signs usually show up in the living space above: floors that feel bouncy, slope, or dip, doors and windows that stick, soft spots underfoot, and gaps opening between the floor and baseboards. If you are seeing any of those, we can get under the home and tell you what is actually causing it.
Yes. Sagging and uneven floors nearly always trace back to failing supports, weakened girders, or damaged joists below. We re-level the floor system by repairing or replacing those members and setting proper support underneath, so the floors sit flat and feel firm again.
Encapsulation seals the space with a heavy vapor barrier across the ground and walls, keeping ground moisture out of your framing. It is a standard part of how we build in the humid Lowcountry rather than an add-on. Whether your home needs full encapsulation or a vapor barrier alone depends on current conditions, and we can tell you after an evaluation.
Yes, and it is one of the most common things we address. We remove the compromised material, verify the joists beneath are sound and repair them if they are not, then install new subfloor that is properly fastened and sits flat.
It depends on the size of the home and the extent of the structural work. A focused repair to a few supports and joists may wrap in a matter of days, while a full rebuild with subfloor replacement and encapsulation runs longer. We provide a realistic timeline with your written quote.
