Crawl Space & Moisture Repair in New Braunfels, TX

Under many of the older homes in New Braunfels, Texas, from the streets around the Plaza to the farmhouses out toward Gruene, there is a crawl space doing quiet structural work. New Braunfels Foundation Repair HQ has spent more than 18 years in those spaces, replacing rotted posts, shimming beams back to height, laying vapor barriers over damp ground, and moving water out from under houses that were never meant to sit over a puddle. When the soil beneath a pier-and-beam home stays wet, the wood above it softens, the floors begin to dip, and the whole house starts telling you about it. Our crew repairs the structure and the moisture together, because fixing one without the other only buys a few seasons before the sag returns.

New Braunfels sits where the Hill Country limestone drops off onto blackland prairie, and the clay on the prairie side of that line holds water like a sealed bowl. Out in the open, sun and wind dry it between rains. Under a house, neither ever reaches it. A crawl space is shaded, still, and cool, so the clay beneath it stays damp long after the yard has dried, and the lots near the Comal and Guadalupe Rivers add a shallow water table underneath that. Ground moisture rises off the soil as vapor and condenses on cool wood, while the clay itself swells in wet spells and shrinks in drought, so the piers ride up and down and open gaps that let the floor drop.

The repair works on two fronts. On the structural side, our crew replaces failed posts with new supports set on proper footings, adds supports where the original builder spaced them too far apart, and shims the beams back to a level line so the beams and joists carrying the house bear evenly again. Where a beam has rotted through, we sister or replace it rather than propping up bad wood.

On the moisture side, the goal is to break the cycle that ruined the wood in the first place. A vapor barrier, heavy polyethylene sheeting laid over the soil with sealed seams and edges, stops ground moisture from rising into the air under the floor. Full encapsulation goes further, wrapping the piers and sealing the perimeter walls so the crawl space becomes a closed, dry chamber, usually with a dehumidifier holding the humidity down. If water is actually flowing in, we cut a drain inside the crawl space to carry it to a sump, and we will tell you plainly when the real fix is outside, where a regraded yard and extended downspouts can stop runoff from ever reaching the underside of the house. Dry soil holds its strength, dry wood keeps its stiffness, and a repair made in those conditions lasts.
