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.
It's easy to dismiss efflorescence as harmless dust, but it actually signals active moisture movement through the wall.
A pump under constant strain tends to fail at the worst possible time β usually during the next big Annapolis storm.
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.
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 βA cracked foundation wall isn't just a cosmetic issue β it's a water entry point and, over time, a structural one. Our Annapolis crews assess whether it's a simple seal or a sign of bigger settlement issues before recommending a fix.
Get a Crack Assessment βAlready have a sump pump that's failing or too small for your Annapolis lot? We'll test it, tell you honestly whether it needs replacing, and size the new one to your actual water volume β not the cheapest unit on the truck.
Schedule a Pump Inspection βSome Annapolis lots need both an interior and exterior system working together β we'll tell you honestly if that's the case rather than selling just one.
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 βHere's exactly what to expect once you call +1-866-476-1348 for Interior Drainage System in Annapolis.
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.
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.
"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."
"Managed our building's parking garage waterproofing project. Kept to the schedule, communicated well with tenants, minimal disruption."
"French drain install took two days like they said it would, not five. Yard was put back together better than before."
"Technician actually explained why the water was coming in instead of just quoting a number. First contractor who's done that for us."
