Free, no-obligation estimates 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 Alexandria 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 Alexandria 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.
Talk to a real Alexandria technician today, not an automated queue. We'll explain what's going on and get you scheduled.
๐ +1-866-476-1348Most Alexandria calls didn't start with a flood โ they started with one of these small signs weeks or months earlier.
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.
A Alexandria sump pump that never rests is usually undersized or nearing the end of its life.
A wall that's starting to bow is a structural issue on top of a water issue โ this jumps to the front of our Alexandria schedule.
These upstairs clues usually show up months after the basement moisture problem actually started.
From a 2 a.m. sump pump failure to a planned exterior drainage project, here's what our Alexandria crews handle most.
When water shows up fast, we move fast โ extraction, drying equipment, and a plan to stop it from happening again.
Get Emergency Help โNot every crack means a structural problem, but every crack deserves a real look. We'll tell you which kind yours is.
Ask About Crack Repair โA failed sump pump is the top reason for emergency calls across Alexandria after heavy rain โ we install pumps sized to your actual water volume, plus battery backup for power outages.
Book a Pump Check โFor yards fighting bad grading, an exterior French drain intercepts water before it ever touches the foundation wall.
Talk Drainage Options โOlder Alexandria homes with vented crawl spaces see the biggest swings in seasonal humidity โ encapsulation closes that off for good.
Get a Crawl Space Quote โWe can phase larger Alexandria commercial projects around business hours or tenant schedules so operations keep running.
