Halo Water Proofing started small in the Lanham area and grew because customers kept referring us to their neighbors — that's still how most of our work comes in today.
Every Lanham technician we send is background-checked and trained on the exact equipment we install — not a subcontractor picked up for the day.
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.
One phone call gets you a straight answer and a real appointment — not a vague callback promise.
📞 +1-866-476-1348Water problems build slowly before they become emergencies. These are the clues our Lanham crews hear about most.
If the basement smells damp no matter the season, water is likely finding a way in somewhere you can't see.
Stair-step cracking in block foundations is one of the most common early signs our Lanham crews see.
Efflorescence is a reliable early sign that water is moving through your Lanham foundation wall right now.
A Lanham sump pump that never rests is usually undersized or nearing the end of its life.
This is one sign we tell Lanham customers never to wait on — wall movement tends to progress, not resolve on its own.
These upstairs clues usually show up months after the basement moisture problem actually started.
Whatever's going on with your Lanham property, chances are we've already fixed something similar nearby this month.

Get Emergency Help →We seal active Lanham foundation cracks with epoxy injection — stopping the leak at its source instead of patching the surface.
Ask About Crack Repair →Most Lanham pump failures happen during the exact storms that need them most, which is exactly why battery backup matters.
Book a Pump Check →Some Lanham properties need both systems working together — we'll say so honestly instead of selling just one.

Request a Commercial Quote →Here's exactly what Lanham customers can expect from first call to final walkthrough.

Word of mouth is still how most Lanham customers find us, which keeps our standards high.
"Called during a storm and had a tech at my door within two hours. Explained everything before touching anything — basement's been dry since."
"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."
