Halo Water Proofing has been the trusted call for Exterior Waterproofing across Kensington because we answer the phone, show up when we say, and stand behind the work.
Licensed & insured in MD · Real warranties
We built Halo Water Proofing around a simple promise: show up when we say, tell you the truth about what's wrong, and fix it so it stays fixed.
Every Kensington technician we send is background-checked and trained on the exact equipment we install — not a subcontractor picked up for the day.
Our Kensington crew leads carry years of hands-on repair experience, not just sales training — 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 — not a vague callback promise.
📞 +1-866-476-1348Water problems build slowly before they become emergencies. These are the clues our Kensington crews hear about most.
Odor is often the very first clue Kensington homeowners notice, well before any water is visible.
A crack that wasn't there last year is worth a look before it becomes an active leak point.
Efflorescence is a reliable early sign that water is moving through your Kensington foundation wall right now.
A Kensington sump pump that never rests is usually undersized or nearing the end of its life.
If a foundation wall looks like it's curving inward, that's beyond a simple patch and needs a real assessment.
Flooring that's cupping near an exterior wall often traces straight back to a basement moisture issue below.
No two Kensington basements are the same — soil type, age of the home, water table. We match the fix to your actual problem.
A flooded Kensington basement doesn't wait for morning, and neither do we. Our crews get it out and start drying the space the same visit.
Get Emergency Help →We seal active Kensington foundation cracks with hydraulic cement injection — stopping the leak at its source instead of patching the surface.
Ask About Crack Repair →Already have a pump that's struggling? We'll test it honestly and tell you whether it needs replacing or just a tune-up.
Book a Pump Check →For yards fighting bad grading, an exterior French drain intercepts water before it ever touches the foundation wall.
Talk Drainage Options →Musty smell upstairs with no obvious source? Check the crawl space first — it's usually the culprit.
Get a Crawl Space Quote →We handle below-grade waterproofing for Kensington property managers and business owners, scheduled around your operating hours to limit disruption.
Request a Commercial Quote →No pressure, no scripts — just what actually happens once you call +1-866-476-1348.
We figure out fast whether this needs an emergency dispatch or a scheduled inspection.
A Kensington technician walks the property, checks the foundation and drainage, and explains what's found in plain language.
Every Kensington quote is written before work starts, not estimated verbally and adjusted later.
Our crew completes the repair, cleans up, and walks you through the warranty on what was installed.
We've heard every Kensington horror story about contractors who disappear mid-job or pad the invoice. Here's how we do it differently.
There's no verbal quote that grows once the crew shows up — the written estimate is final.
Our crews stage locally near Kensington, which is why most emergency calls get a technician on-site in under two hours.
Our major repairs come with written, transferable warranties — useful if you sell the Kensington property later.
We'd rather earn a repeat Kensington customer with an honest fix than push a system you don't need.
Filing a claim can be confusing — we've walked Kensington customers through this process many times.
Every Kensington job reflects on the next referral, so we treat each one like it matters.
"Woke up to a wet basement and had someone out by mid-morning. No pressure, no upsell, just fixed it."
"Fair price, on time, cleaned up after. Wish every contractor worked this way."
"Crawl space smelled bad for years. After encapsulation, the smell upstairs is completely gone."
"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."
"First contractor who actually explained where the water was coming from instead of just quoting a number."
"Sump pump inspection was thorough and they didn't try to sell me a new one when mine just needed a part replaced."
Every Kensington technician we send is background-checked and trained on the systems we install, so the crew that inspects your property is the same one that fixes it.
