From a hairline crack to a fully soaked crawl space, our Alto crew has seen it and fixed it. No guesswork, no scare tactics โ just a clear plan and a fair price.
Background-checked Alto technicians ยท Written pricing

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.
Every Alto technician we send is background-checked and trained on the exact equipment we install โ not a subcontractor picked up for the day.
We've worked on foundations from decades-old Alto 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 โ not a vague callback promise.

If the basement smells damp no matter the season, water is likely finding a way in somewhere you can't see.
A crack that wasn't there last year is worth a look before it becomes an active leak point.
That white powder on basement walls is mineral residue left behind as water passes through the concrete.

If a foundation wall looks like it's curving inward, that's beyond a simple patch and needs a real assessment.
These upstairs clues usually show up months after the basement moisture problem actually started.
