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.

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

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 +1-866-476-1348Most Annapolis customers didn't wake up one day with a flooded basement. It usually started small. These are the early signs worth calling about.
A musty smell in the basement or crawl space is usually moisture you can't see yet, not just "old house smell."
Stair-step cracks in block foundations are a common early warning sign we see across Annapolis-area homes.
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.
Peeling paint low on a basement wall or warped baseboards upstairs often trace back to moisture migrating up from below.
Every Annapolis property is different β soil, slope, foundation age, water table depth. We size the fix to the actual problem, not a one-size package.
When your Annapolis basement floods, minutes matter for your drywall, flooring, and belongings. We dispatch a crew fast, pull the water, and start drying the space with commercial-grade equipment the same visit.
Call for Emergency Service βHairline cracks are how most Annapolis basements start leaking. We use polyurethane 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 battery backup units 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.
We start with a phone conversation, not a script β enough to know whether this is an emergency dispatch or a scheduled inspection.
A technician inspects the Annapolis 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 β the number you approve is the number you're billed.
Once the repair is done, you get documentation of the work and a written warranty β not just a handshake.
You get a written number before any work begins β the price you approve is the price you pay, no change-order games.
A local dispatch model means the technician who answers questions about your Annapolis job is the same one who shows up to do it.
Our repairs come with written, transferable warranties β a real asset if you sell the Annapolis property later.
We'd rather earn a repeat customer with an honest small fix than push a system you don't need.

"Called at 6am with a flooded basement and had a tech at my door by 8. No runaround, no upsell β just fixed it."
"Fair price, showed up on time, cleaned up after themselves. Wish more contractors worked like this."
"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."
"French drain install took two days like they said it would, not five. Yard was put back together better than before."
