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

Halo Water Proofing is a licensed and insured Basement 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.

We don't send apprentices to figure it out on your dime. Every Annapolis 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.
One call gets you a straight answer and a real appointment window β not a call-back promise.
π +1-866-476-1348Water problems rarely announce themselves all at once β they usually show up as small clues first. Here's what our Annapolis technicians hear about most often before an inspection.
If the basement smells damp even when it looks dry, moisture is likely moving through the walls or floor somewhere.
Even small cracks are worth a second look β they rarely stay small once seasonal ground movement gets involved.
That white chalky film on basement walls is efflorescence β mineral deposits left behind as water evaporates through concrete.
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 Annapolis customers not to wait on β wall movement tends to progress rather than resolve on its own.
Flooring that's cupping or warping near an exterior wall is a common clue our Annapolis crews trace back to a drainage issue.
From an emergency pump swap at 2 a.m. to a full exterior drainage system, this is the work we do in Annapolis every day.
Standing water in your basement doesn't wait for business hours, and neither do we. Our Annapolis emergency crews extract standing water first, then diagnose the source so it doesn't happen again next storm.
Call for Emergency Service βHairline cracks are how most Annapolis basements start leaking. We use epoxy injection to seal the crack from the inside out, stopping the leak at the source instead of just painting over the symptom.
Get a Crack Assessment βA tired or undersized sump pump is the #1 reason we get emergency calls in Annapolis after heavy rain. We install right-sized primary pumps so your basement stays dry even if the power goes out mid-storm.
Schedule a Pump Inspection βAn interior drain tile system channels water to a sump pump before it ever reaches your Annapolis basement floor β one of the most reliable long-term fixes we install.
Ask About Drain Systems βOlder Annapolis homes with vented crawl spaces are especially prone to seasonal moisture swings β encapsulation closes that off for good.
Get a Crawl Space Quote βWe work directly with Annapolis property managers and business owners on below-grade waterproofing, parking structure sealing, and large-scale drainage corrections β scheduled around your operating hours.
Request a Commercial Quote βNo confusing steps, no hard sell β just the same process our Annapolis crews follow on every job.
You call +1-866-476-1348 and talk to a real technician who asks the right questions to understand what's likely happening at your Annapolis property.
We walk the space with you, point out what we find, and explain it in plain language β no jargon, no pressure.
No verbal estimates that change later. What's quoted for your Annapolis job is what's invoiced.
Our crew completes the work, cleans up the site, and walks you through the warranty coverage on what was installed.
There's no verbal quote that magically grows once the crew arrives at your Annapolis property β the written estimate is the final word.
Because we're actually based near Annapolis rather than routing calls through a national center, we can usually get someone out the same day you call.
Our repairs come with written, transferable warranties β a real asset if you sell the Annapolis property later.
Our technicians are paid to diagnose correctly, not to upsell β that changes the advice you actually get on-site.
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 Annapolis job reflects on the next referral, so we treat each one like it's the only advertising that matters.
"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."
"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 β they didn't try to sell us on the other two. That honesty is rare."
"Technician actually explained why the water was coming in instead of just quoting a number. First contractor who's done that for us."
