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

We're Halo Water Proofing — a MD-licensed, fully insured waterproofing outfit that's spent years learning exactly how water moves through Glen Echo-area foundations, and exactly how to stop it.

We don't send apprentices to figure it out on your dime. Every Glen Echo job is run by a technician who has done this exact repair dozens of times, with a supervisor who signs off before we call it finished.
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.
📞 +1-866-476-1348Water problems rarely announce themselves all at once — they usually show up as small clues first. Here's what our Glen Echo technicians hear about most often before an inspection.
Odor is often the first sign Glen Echo customers notice, well before any visible water shows up.
Hairline cracks can widen over a Glen Echo winter's freeze-thaw cycle and become active leak points by spring.
Efflorescence is a clear sign that water is actively passing through your Glen Echo foundation wall, even if you've never seen standing water.
A pump under constant strain tends to fail at the worst possible time — usually during the next big Glen Echo storm.
A bowing basement wall is a structural concern in addition to a water one — this is the kind of Glen Echo call we prioritize fast.
These signs upstairs are often the last clue Glen Echo 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 Glen Echo every day.
Standing water in your basement doesn't wait for business hours, and neither do we. Our Glen Echo emergency crews remove the water first, then diagnose where it's getting in so it doesn't happen again next storm.
Call for Emergency Service →Freeze-thaw cycles in Glen Echo, 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 Glen Echo 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 Glen Echo 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 Glen Echo 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 Glen Echo commercial projects around business hours or tenant schedules so operations aren't disrupted mid-project.
Request a Commercial Quote →No confusing steps, no hard sell — just the same process our Glen Echo crews follow on every job.
We start with a phone conversation, not a script — enough to know whether this is an emergency dispatch or a scheduled inspection.
A technician inspects the Glen Echo property in person, checking the foundation, drainage, grading, and any active moisture before recommending a fix.
You receive a written, itemized quote before any work begins — the number you approve is the number you're billed.
Our crew completes the work, cleans up the site, and walks you through the warranty coverage on what was installed.
You get a written number before any work begins — the price you approve is the price you pay, no change-order games.
Because we're actually based near Glen Echo rather than routing calls through a national center, we can usually get someone out the same day you call.
If a covered repair fails, we come back and make it right. That's written into every contract, not just promised on the phone.
If your Glen Echo basement just needs a $200 crack seal instead of a $12,000 system, that's what we'll tell you.
We document the damage with photos and a written scope your insurance adjuster can actually use, and we'll walk you through the claim process.
Every Glen Echo job reflects on the next referral, so we treat each one like it's the only advertising that matters.
"Called at 6am with a flooded basement and had a tech at my door by 8. No runaround, no upsell — just fixed it."
"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."
"Our old sump pump died during the worst storm of the year, obviously. They had a battery backup system installed within a day. Haven't worried about it since."
"Straightforward commercial quote, no back-and-forth, crew was professional the whole project."
"We had three foundation cracks and expected a huge bill. Turned out only one needed injection — they didn't try to sell us on the other two. That honesty is rare."
"Insurance claim was a headache until they stepped in with photos and a written scope. Adjuster approved it within a week after that."
