Licensed & insured in MD Β· Real warranties

Halo Water Proofing is a MD-licensed Wet Basement Repair company that treats every Annapolis job like it's the only one on the schedule.
Every Annapolis technician we send is background-checked and trained on the exact equipment we install β not a subcontractor picked up for the day.
Our Annapolis crew leads carry years of hands-on repair experience, not just sales training β which is why the advice you get on-site tends to match what actually needs fixing.
One phone call gets you a straight answer and a real appointment β not a vague callback promise.
π +1-866-476-1348Catching one of these early usually means a smaller repair bill and a lot less stress for Annapolis homeowners.
A musty smell usually means moisture is already moving through your Annapolis basement, even if the floor looks bone dry.
Stair-step cracking in block foundations is one of the most common early signs our Annapolis crews see.
It's easy to mistake efflorescence for harmless dust, but it actually signals active moisture movement.
A pump under constant strain tends to fail during the exact storm that needs it most.
A wall that's starting to bow is a structural issue on top of a water issue β this jumps to the front of our Annapolis schedule.
These upstairs clues usually show up months after the basement moisture problem actually started.
No two Annapolis basements are the same β soil type, age of the home, water table. We match the fix to your actual problem.
When water shows up fast, we move fast β extraction, drying equipment, and a plan to stop it from happening again.
Get Emergency Help βWe seal active Annapolis foundation cracks with epoxy injection β stopping the leak at its source instead of patching the surface.
Ask About Crack Repair βMost Annapolis pump failures happen during the exact storms that need them most, which is exactly why battery backup matters.
Book a Pump Check βFor yards fighting bad grading, an exterior French drain intercepts water before it ever touches the foundation wall.
Talk Drainage Options βOlder Annapolis homes with vented crawl spaces see the biggest swings in seasonal humidity β encapsulation closes that off for good.
Get a Crawl Space Quote βWe handle below-grade waterproofing for Annapolis property managers and business owners, scheduled around your operating hours to limit disruption.
Request a Commercial Quote βNo pressure, no scripts β just what actually happens once you call +1-866-476-1348.
A real technician asks the right questions to understand what's likely happening at your Annapolis property before anyone drives out.
A Annapolis technician walks the property, checks the foundation and drainage, and explains what's found in plain language.
The number you approve is the number you're billed β no change orders once the crew shows up.
Once the job's done, you get written proof of what was installed and exactly what the warranty covers.
We've heard every Annapolis horror story about contractors who disappear mid-job or pad the invoice. Here's how we do it differently.
You get a real number before any work starts β what you approve is what you're billed.
We're not routing your call through a national center β the person who answers is close by.
Our major repairs come with written, transferable warranties β useful if you sell the Annapolis property later.
Our technicians are trained to diagnose accurately, not to upsell β that changes the advice you actually get.
We photograph the damage and provide a written scope your insurance adjuster can actually use.
Every Annapolis job reflects on the next referral, so we treat each one like it matters.
"Called during a storm and had a tech at my door within two hours. Explained everything before touching anything β basement's been dry since."
"Fair price, on time, cleaned up after. Wish every contractor worked this way."
"Our sump pump died during the worst storm of the year, obviously. Battery backup was installed the next day and we haven't worried since."
"Handled waterproofing for our parking structure with minimal disruption to tenants and stuck to the schedule."
"French drain install took two days exactly as quoted, and the yard looked better than before."
"Insurance claim was stressful until they stepped in with photos and a written scope. Approved within a week."
"Crew was respectful of our landscaping during the drain install and left the yard looking better than before they started."
We back our Annapolis work with real, transferable warranties because we plan to be here long after the job is done, not just for the one visit.
