Licensed & insured in MD · 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.
Our Lansdowne crew leads have handled repairs like yours dozens of times before, and a supervisor signs off before we call any job finished.
Our Lansdowne 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.
One phone call gets you a straight answer and a real appointment — not a vague callback promise.

Every Lansdowne job reflects on the next referral, so we treat each one like it matters.
"Woke up to a wet basement and had someone out by mid-morning. No pressure, no upsell, just fixed it."
"Fair price, on time, cleaned up after. Wish every contractor worked this way."
"Our sump pump died during the worst storm of the year, obviously. Battery backup was installed the next day and we haven't worried since."
"Handled waterproofing for our parking structure with minimal disruption to tenants and stuck to the schedule."
"Expected a huge bill for three cracks, only one actually needed injection. Appreciated the honesty."
"First contractor who actually explained where the water was coming from instead of just quoting a number."
"Sump pump inspection was thorough and they didn't try to sell me a new one when mine just needed a part replaced."
If a covered repair doesn't hold up, we come back and make it right — no arguing, no extra invoice. That's written into every Lansdowne contract we sign.
