Halo Water Proofing has been the trusted call for Wet Basement Repair across Adelphi because we answer the phone, show up when we say, and stand behind the work.
Licensed & insured in MD · 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 Adelphi technician who inspects your property is the same one who does the repair, start to finish.
We've worked on foundations from decades-old Adelphi 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 Adelphi technician today, not an automated queue. We'll explain what's going on and get you scheduled.
📞 +1-866-476-1348Water problems build slowly before they become emergencies. These are the clues our Adelphi crews hear about most.
Odor is often the very first clue Adelphi homeowners notice, well before any water is visible.
Small cracks in a Adelphi foundation rarely stay small — seasonal ground movement tends to widen them over time.
That white powder on basement walls is mineral residue left behind as water passes through the concrete.
A pump under constant strain tends to fail during the exact storm that needs it most.
If a foundation wall looks like it's curving inward, that's beyond a simple patch and needs a real assessment.
Peeling paint near the floor upstairs is one of the last signs Adelphi homeowners connect to a basement problem.
From a 2 a.m. sump pump failure to a planned exterior drainage project, here's what our Adelphi crews handle most.

Get Emergency Help →Seasonal ground movement in Adelphi tends to widen existing cracks over time, so sealing early usually costs less than waiting.
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.
