Free, no-obligation estimates · 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 Halethorpe 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 Halethorpe 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.

If the basement smells damp no matter the season, water is likely finding a way in somewhere you can't see.

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.

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

"Called during a storm and had a tech at my door within two hours. Explained everything before touching anything — basement's been dry since."
