From a hairline crack to a fully soaked crawl space, our Alamo crew has seen it and fixed it. No guesswork, no scare tactics — just a clear plan and a fair price.
Free, no-obligation estimates · 24/7 dispatch
We built Halo Water Proofing around a simple promise: show up when we say, tell you the truth about what's wrong, and fix it so it stays fixed.
We don't run a bidding war between crews. The Alamo technician who inspects your property is the same one who does the repair, start to finish.
We've worked on foundations from decades-old Alamo homes to brand-new builds still settling into their soil, so whatever your basement is dealing with, we've likely seen a version of it nearby.
One phone call gets you a straight answer and a real appointment — not a vague callback promise.

A musty smell usually means moisture is already moving through your Alamo basement, even if the floor looks bone dry.

These upstairs clues usually show up months after the basement moisture problem actually started.
No two Alamo basements are the same — soil type, age of the home, water table. We match the fix to your actual problem.
A flooded Alamo basement doesn't wait for morning, and neither do we. Our crews pull the standing water and start drying the space the same visit.
