Halo Water Proofing is a MD-licensed Vapor Barrier Installation company that treats every Lanham job like it's the only one on the schedule.
Every Lanham technician we send is background-checked and trained on the exact equipment we install — not a subcontractor picked up for the day.
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.
Talk to a real Lanham technician today, not an automated queue. We'll explain what's going on and get you scheduled.
📞 +1-866-476-1348Water problems build slowly before they become emergencies. These are the clues our Lanham crews hear about most.
Odor is often the very first clue Lanham homeowners notice, well before any water is visible.
A crack that wasn't there last year is worth a look before it becomes an active leak point.
That white powder on basement walls is mineral residue left behind as water passes through the concrete.
A Lanham sump pump that never rests is usually undersized or nearing the end of its life.
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.
These upstairs clues usually show up months after the basement moisture problem actually started.
From a 2 a.m. sump pump failure to a planned exterior drainage project, here's what our Lanham crews handle most.
Storm season keeps our Lanham emergency line busy — active flooding always jumps ahead of routine inspections in the queue.
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 →For yards fighting bad grading, an exterior French drain intercepts water before it ever touches the foundation wall.
Talk Drainage Options →Older Lanham homes with vented crawl spaces see the biggest swings in seasonal humidity — encapsulation closes that off for good.
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.
You'll talk to a person, not a script — enough of a conversation to know what to expect before anyone shows up.
No jargon, no pressure — just a clear look at what's actually going on.
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.
There's no verbal quote that grows once the crew shows up — the written estimate is final.
We're not routing your call through a national center — the person who answers is close by.
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.
Filing a claim can be confusing — we've walked Lanham customers through this process many times.
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."
"Crawl space smelled bad for years. After encapsulation, the smell upstairs is completely gone."
"Handled waterproofing for our parking structure with minimal disruption to tenants and stuck to the schedule."
"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."
"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 Lanham contract we sign.
