Wet basement? Cracked foundation? A Halo Water Proofing crew can be at your Annapolis property today β upfront pricing, no guesswork, no pressure.

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.
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.
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.
Odor is often the first sign Annapolis customers notice, well before any visible water shows up.
Stair-step cracks in block foundations are a common early warning sign we see across Annapolis-area homes.
Efflorescence is a clear sign that water is actively passing through your Annapolis foundation wall, even if you've never seen standing water.
A pump under constant strain tends to fail at the worst possible time β usually during the next big Annapolis storm.
If a foundation wall looks like it's leaning or bulging inward, that's beyond a simple seal and needs a full assessment.
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.
Storm season in Annapolis, MD means our emergency line gets busy fast β we triage calls by severity so active flooding at your Annapolis address jumps the queue ahead of routine inspections.
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 βCommercial properties in Annapolis carry bigger stakes when water gets in: inventory, tenants, downtime. We scope commercial jobs with the same crew leads who run our residential work, backed by written specs and timelines.
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.
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.
A local dispatch model means the technician who answers questions about your Annapolis job is the same one who shows up to do it.
Warranty terms are explained before you sign, in plain language, so there's no fine print surprise if you ever need to use it.
We'd rather earn a repeat customer with an honest small fix than push a system you don't need.
Filing a water damage claim in Annapolis, MD can be confusing β we've done it enough times with Annapolis adjusters to help you avoid common denials.

"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."
