Halo Water Proofing has been the trusted call for Basement Waterproofing across Lanham because we answer the phone, show up when we say, and stand behind the work.
Licensed & insured in MD · Real warranties
Halo Water Proofing is a MD-licensed Basement Waterproofing company that treats every Lanham job like it's the only one on the schedule.
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.
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.
A musty smell usually means moisture is already moving through your Lanham basement, even if the floor looks bone dry.
Small cracks in a Lanham foundation rarely stay small — seasonal ground movement tends to widen them over time.
It's easy to mistake efflorescence for harmless dust, but it actually signals active moisture movement.
If your pump only shuts off for a few minutes at a time, it's worth having it checked before it fails outright.
A wall that's starting to bow is a structural issue on top of a water issue — this jumps to the front of our Lanham schedule.
Flooring that's cupping near an exterior wall often traces straight back to a basement moisture issue below.
Whatever's going on with your Lanham property, chances are we've already fixed something similar nearby this month.
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 →A failed sump pump is the top reason for emergency calls across Lanham after heavy rain — we install pumps sized to your actual water volume, plus battery backup for power outages.
Book a Pump Check →For yards fighting bad grading, an exterior French drain intercepts water before it ever touches the foundation wall.
Talk Drainage Options →Musty smell upstairs with no obvious source? Check the crawl space first — it's usually the culprit.
Get a Crawl Space Quote →We can phase larger Lanham commercial projects around business hours or tenant schedules so operations keep running.
Request a Commercial Quote →No pressure, no scripts — just what actually happens once you call +1-866-476-1348.
We figure out fast whether this needs an emergency dispatch or a scheduled inspection.
A Lanham technician walks the property, checks the foundation and drainage, and explains what's found in plain language.
Every Lanham quote is written before work starts, not estimated verbally and adjusted later.
Our crew completes the repair, cleans up, and walks you through the warranty on what was installed.
Plenty of companies advertise Basement Waterproofing in Lanham — here's what actually separates the ones worth calling from the ones that aren't.
There's no verbal quote that grows once the crew shows up — the written estimate is final.
Our crews stage locally near Lanham, which is why most emergency calls get a technician on-site in under two hours.
If a covered repair fails, we come back and fix it. That's part of the contract, not just a promise.
If your Lanham basement just needs a small crack seal instead of a full system, that's exactly what we'll tell you.
We photograph the damage and provide a written scope your insurance adjuster can actually use.
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."
"Got three quotes for a crack repair. This was the only company that actually explained why the crack was happening instead of just naming a price."
"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."
"Straightforward commercial quote, professional crew, no back and forth."
"French drain install took two days exactly as quoted, and the yard looked better than before."
"First contractor who actually explained where the water was coming from instead of just quoting a number."
