From a hairline crack to a fully soaked crawl space, our De Graff 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.
Every De Graff technician we send is background-checked and trained on the exact equipment we install — not a subcontractor picked up for the day.
We've worked on foundations from decades-old De Graff 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.
📞 +1-866-476-1348Most De Graff calls didn't start with a flood — they started with one of these small signs weeks or months earlier.
Odor is often the very first clue De Graff homeowners notice, well before any water is visible.
Stair-step cracking in block foundations is one of the most common early signs our De Graff crews see.
It's easy to mistake efflorescence for harmless dust, but it actually signals active moisture movement.
A De Graff 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 — this jumps to the front of our De Graff schedule.
These upstairs clues usually show up months after the basement moisture problem actually started.
No two De Graff basements are the same — soil type, age of the home, water table. We match the fix to your actual problem.
Storm season keeps our De Graff emergency line busy — active flooding always jumps ahead of routine inspections in the queue.
Get Emergency Help →Not 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 →Already have a pump that's struggling? We'll test it honestly and tell you whether it needs replacing or just a tune-up.
Book a Pump Check →Some De Graff properties need both systems working together — we'll say so honestly instead of selling just one.
Talk Drainage Options →Older De Graff homes with vented crawl spaces see the biggest swings in seasonal humidity — encapsulation closes that off for good.

Request a Commercial Quote →No pressure, no scripts — just what actually happens once you call +1-866-476-1348.
