Halo Water Proofing has been the trusted call for Wet Basement Repair across White Marsh because we answer the phone, show up when we say, and stand behind the work.
Licensed & insured in MD · Real warranties
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 White Marsh 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 White Marsh 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 White Marsh technician today, not an automated queue. We'll explain what's going on and get you scheduled.
📞 +1-866-476-1348Most White Marsh calls didn't start with a flood — they started with one of these small signs weeks or months earlier.
A musty smell usually means moisture is already moving through your White Marsh basement, even if the floor looks bone dry.
Small cracks in a White Marsh 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.
A wall that's starting to bow is a structural issue on top of a water issue — this jumps to the front of our White Marsh schedule.
Flooring that's cupping near an exterior wall often traces straight back to a basement moisture issue below.
No two White Marsh basements are the same — soil type, age of the home, water table. We match the fix to your actual problem.
When water shows up fast, we move fast — extraction, drying equipment, and a plan to stop it from happening again.
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 →An interior drain tile system routes water to a sump pump before it reaches your White Marsh basement floor at all.
Talk Drainage Options →A damp White Marsh crawl space drives up humidity throughout the house — we seal it completely with heavy-duty vapor barrier and add dehumidification where needed.
