Halo Water Proofing has been the trusted call for Interior Drainage System across Lanham because we answer the phone, show up when we say, and stand behind the work.
Licensed & insured in MD · 24/7 dispatch
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.
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.
We've worked on foundations from decades-old Lanham homes to brand-new builds still settling into their soil, so whatever your basement is dealing with, we've likely seen a version of it nearby.
One phone call gets you a straight answer and a real appointment — not a vague callback promise.
📞 +1-866-476-1348Most Lanham calls didn't start with a flood — they started with one of these small signs weeks or months earlier.
If the basement smells damp no matter the season, water is likely finding a way in somewhere you can't see.
A crack that wasn't there last year is worth a look before it becomes an active leak point.
It's easy to mistake efflorescence for harmless dust, but it actually signals active moisture movement.
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.
Flooring that's cupping near an exterior wall often traces straight back to a basement moisture issue below.
No two Lanham basements are the same — soil type, age of the home, water table. We match the fix to your actual problem.
A flooded Lanham basement doesn't wait for morning, and neither do we. Our crews extract it fast and start drying the space the same visit.
Get Emergency Help →Seasonal ground movement in Lanham tends to widen existing cracks over time, so sealing early usually costs less than waiting.
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.
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 handle below-grade waterproofing for Lanham property managers and business owners, scheduled around your operating hours to limit disruption.
Request a Commercial Quote →Here's exactly what Lanham customers can expect from first call to final walkthrough.
A real technician asks the right questions to understand what's likely happening at your Lanham property before anyone drives out.
We point out exactly what we find as we find it, so nothing about the diagnosis feels like a black box.
Every Lanham quote is written before work starts, not estimated verbally and adjusted later.
You get documentation of the work plus a real warranty — not just a handshake.
We've heard every Lanham horror story about contractors who disappear mid-job or pad the invoice. Here's how we do it differently.
You get a real number before any work starts — what you approve is what you're billed.
A local dispatch model means the technician who answers your questions is the same one who shows up.
If a covered repair fails, we come back and fix it. That's part of the contract, not just a promise.
We'd rather earn a repeat Lanham customer with an honest fix than push a system you don't need.
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.
"Woke up to a wet basement and had someone out by mid-morning. No pressure, no upsell, just fixed it."
"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."
"Crawl space smelled bad for years. After encapsulation, the smell upstairs is completely gone."
"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."
"Crew was respectful of our landscaping during the drain install and left the yard looking better than before they started."
We back our Lanham work with real, transferable warranties because we plan to be here long after the job is done, not just for the one visit.
