Halo Water Proofing has been the Lanham area's go-to call for Waterproofing because we answer the phone, show up on time, and stand behind the work.

Halo Water Proofing is a licensed and insured Waterproofing company built around one idea: show up when you say you will, explain the problem in plain language, and fix it so it stays fixed.

Every technician on our Lanham crew is background-checked, factory-trained on the equipment we install, and held to the same estimate we quote you over the phone — no upsell surprises when the truck pulls up.
Call now and talk to an actual technician, not a script. We'll walk you through what's likely going on and get a crew scheduled.
📞 +1-866-476-1348Most Lanham customers didn't wake up one day with a flooded basement. It usually started small. These are the early signs worth calling about.
If the basement smells damp even when it looks dry, moisture is likely moving through the walls or floor somewhere.
Stair-step cracks in block foundations are a common early warning sign we see across Lanham-area homes.
Efflorescence is a clear sign that water is actively passing through your Lanham foundation wall, even if you've never seen standing water.
If your pump is running around the clock instead of only during storms, it's worth having it evaluated before it fails completely.
This is one sign we tell Lanham customers not to wait on — wall movement tends to progress rather than resolve on its own.
These signs upstairs are often the last clue Lanham homeowners notice, even though the moisture issue started in the basement months earlier.
From an emergency pump swap at 2 a.m. to a full exterior drainage system, this is the work we do in Lanham every day.
When your Lanham basement floods, minutes matter for your drywall, flooring, and belongings. We dispatch a crew immediately, pull the water, and start drying the space with commercial-grade equipment the same visit.
Call for Emergency Service →Freeze-thaw cycles in Lanham, MD push existing cracks wider every winter, which is why we recommend sealing them before they become an active leak rather than after.
Get a Crack Assessment →Already have a sump pump that's failing or too small for your Lanham lot? We'll test it, tell you honestly whether it needs replacing, and size the new one to your actual water volume — not the cheapest unit on the truck.
Schedule a Pump Inspection →For Lanham properties fighting grading or drainage issues, an exterior French drain can intercept water before it ever reaches the foundation wall at all. We map your yard's slope and water flow before recommending which approach fits.
Ask About Drain Systems →Musty smell upstairs that you can't explain? It's usually the crawl space. Our Lanham crews encapsulate the space fully — floor, walls, and vents — so moisture stops migrating into your living areas.
Get a Crawl Space Quote →We can phase larger Lanham commercial projects around business hours or tenant schedules so operations aren't disrupted mid-project.

We start with a phone conversation, not a script — enough to know whether this is an emergency dispatch or a scheduled inspection.
We walk the space with you, point out what we find, and explain it in plain language — no jargon, no pressure.
No verbal estimates that change later. What's quoted for your Lanham job is what's invoiced.
Once the repair is done, you get documentation of the work and a written warranty — not just a handshake.
You get a written number before any work begins — the price you approve is the price you pay, no change-order games.
A local dispatch model means the technician who answers questions about your Lanham job is the same one who shows up to do it.
Warranty terms are explained before you sign, in plain language, so there's no fine print surprise if you ever need to use it.
Our technicians are paid to diagnose correctly, not to upsell — that changes the advice you actually get on-site.
We can supply the photo documentation and repair scope most Lanham, MD carriers ask for before approving a claim.
Word of mouth is still how most Lanham customers find us, which keeps our standards higher than a big out-of-town franchise.
"They came out the same afternoon I called about water coming in during a storm. Explained everything before they touched anything. Basement's been bone dry since."
"Got quotes from three companies for a crack repair. These guys were the only ones who actually explained why the crack was happening instead of just quoting a price."
"Crawl space smelled awful for years. Encapsulation crew did a clean job and the smell is completely gone upstairs now."
"Managed our building's parking garage waterproofing project. Kept to the schedule, communicated well with tenants, minimal disruption."
"French drain install took two days like they said it would, not five. Yard was put back together better than before."
"Insurance claim was a headache until they stepped in with photos and a written scope. Adjuster approved it within a week after that."
