From a hairline foundation crack to a fully flooded crawl space, Halo Water Proofing has handled it in Derby before. We show up, we diagnose it straight, and we fix it right.

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

We don't send apprentices to figure it out on your dime. Every Derby 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.
📞 +1-866-476-1348Water problems rarely announce themselves all at once — they usually show up as small clues first. Here's what our Derby technicians hear about most often before an inspection.
Odor is often the first sign Derby customers notice, well before any visible water shows up.
Hairline cracks can widen over a Derby winter's freeze-thaw cycle and become active leak points by spring.
It's easy to dismiss efflorescence as harmless dust, but it actually signals active moisture movement through the wall.
A sump pump that never stops cycling is often working harder than it should, or is undersized for your Derby lot's water table.
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 Derby crews trace back to a drainage issue.
From an emergency pump swap at 2 a.m. to a full exterior drainage system, this is the work we do in Derby every day.
Standing water in your basement doesn't wait for business hours, and neither do we. Our Derby emergency crews pump out the basement first, then diagnose where it's getting in so it doesn't happen again next storm.
Call for Emergency Service →A cracked foundation wall isn't just a cosmetic issue — it's a water entry point and, over time, a structural one. Our Derby crews assess whether it's a simple seal or a sign of bigger settlement issues before recommending a fix.
Get a Crack Assessment →Already have a sump pump that's failing or too small for your Derby lot? We'll test it, tell you honestly whether it needs replacing, and size the new one to your actual water volume — not the cheapest unit on the truck.
Schedule a Pump Inspection →An interior drain tile system channels water to a sump pump before it ever reaches your Derby basement floor — one of the most reliable long-term fixes we install.
Ask About Drain Systems →Older Derby homes with vented crawl spaces are especially prone to seasonal moisture swings — encapsulation closes that off for good.
Get a Crawl Space Quote →We can phase larger Derby commercial projects around business hours or tenant schedules so operations aren't disrupted mid-project.
Request a Commercial Quote →No confusing steps, no hard sell — just the same process our Derby crews follow on every job.
We start with a phone conversation, not a script — enough to know whether this is an emergency dispatch or a scheduled inspection.
A technician inspects the Derby property in person, checking the foundation, drainage, grading, and any active moisture before recommending a fix.
No verbal estimates that change later. What's quoted for your Derby job is what's invoiced.
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 Derby property — the written estimate is the final word.
Our trucks stage locally around Derby, which is why emergency calls typically get a technician on-site in under two hours, not "sometime tomorrow."
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.
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.
Word of mouth is still how most Derby customers find us, which keeps our standards higher than a big out-of-town franchise.
"Called at 6am with a flooded basement and had a tech at my door by 8. No runaround, no upsell — just fixed it."
"Fair price, showed up on time, cleaned up after themselves. Wish more contractors worked like this."
"Crawl space smelled awful for years. Encapsulation crew did a clean job and the smell is completely gone upstairs now."
"Straightforward commercial quote, no back-and-forth, crew was professional the whole project."
"We had three foundation cracks and expected a huge bill. Turned out only one needed injection — they didn't try to sell us on the other two. That honesty is rare."
"Technician actually explained why the water was coming in instead of just quoting a number. First contractor who's done that for us."
