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

Halo Water Proofing started as a small MD crew and grew because Upperco customers kept referring us to neighbors — that's still how most of our work comes in today.

We don't send apprentices to figure it out on your dime. Every Upperco 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 — not a call-back promise.
📞 +1-866-476-1348Water problems rarely announce themselves all at once — they usually show up as small clues first. Here's what our Upperco technicians hear about most often before an inspection.
Odor is often the first sign Upperco customers notice, well before any visible water shows up.
Hairline cracks can widen over a Upperco 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.
If your pump is running around the clock instead of only during storms, it's worth having it evaluated before it fails completely.
If a foundation wall looks like it's leaning or bulging inward, that's beyond a simple seal and needs a full assessment.
These signs upstairs are often the last clue Upperco homeowners notice, even though the moisture issue started in the basement months earlier.
Every Upperco property is different — soil, slope, foundation age, water table depth. We size the fix to the actual problem, not a one-size package.
When your Upperco 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 →A cracked foundation wall isn't just a cosmetic issue — it's a water entry point and, over time, a structural one. Our Upperco 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 Upperco 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 Upperco basement floor — one of the most reliable long-term fixes we install.
Ask About Drain Systems →A damp, uninsulated crawl space under a Upperco home drives up humidity, invites mold, and wastes energy year-round. We seal it with heavy-duty vapor barrier, address any standing moisture, and can add dehumidification if needed.
Get a Crawl Space Quote →We can phase larger Upperco 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 Upperco 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.
We walk the space with you, point out what we find, and explain it in plain language — no jargon, no pressure.
You receive a written, itemized quote before any work begins — 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 Upperco property — the written estimate is the final word.
A local dispatch model means the technician who answers questions about your Upperco 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.
Our technicians are paid to diagnose correctly, not to upsell — that changes the advice you actually get on-site.

"They came out the same afternoon I called about water coming in during a storm. Explained everything before they touched anything. Basement's been bone dry since."
"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."
