Halo Water Proofing has been the trusted call for Wet Basement Repair across Lanham 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 Lanham technician who inspects your property is the same one who does the repair, start to finish.
Our Lanham crew leads carry years of hands-on repair experience, not just sales training — which is why the advice you get on-site tends to match what actually needs fixing.
Talk to a real Lanham technician today, not an automated queue. We'll explain what's going on and get you scheduled.

Once the job's done, you get written proof of what was installed and exactly what the warranty covers.
We've heard every Lanham horror story about contractors who disappear mid-job or pad the invoice. Here's how we do it differently.

A local dispatch model means the technician who answers your questions is the same one who shows up.

We photograph the damage and provide a written scope your insurance adjuster can actually use.
Our trucks are recognizable around Lanham — we don't cut corners on jobs our neighbors will see.
