Halo Water Proofing has been the Cheltenham area's go-to call for Interior Drainage System because we answer the phone, show up on time, and stand behind the work.

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

Every technician on our Cheltenham crew is background-checked, factory-trained on the equipment we install, and held to the same estimate we quote you over the phone — no upsell surprises when the truck pulls up.
One call gets you a straight answer and a real appointment window — not a call-back promise.
📞 +1-866-476-1348Most Cheltenham customers didn't wake up one day with a flooded basement. It usually started small. These are the early signs worth calling about.
Odor is often the first sign Cheltenham customers notice, well before any visible water shows up.
Stair-step cracks in block foundations are a common early warning sign we see across Cheltenham-area homes.
That white chalky film on basement walls is efflorescence — mineral deposits left behind as water evaporates through concrete.
A sump pump that never stops cycling is often working harder than it should, or is undersized for your Cheltenham lot's water table.
A bowing basement wall is a structural concern in addition to a water one — this is the kind of Cheltenham call we prioritize fast.
Peeling paint low on a basement wall or warped baseboards upstairs often trace back to moisture migrating up from below.
From an emergency pump swap at 2 a.m. to a full exterior drainage system, this is the work we do in Cheltenham every day.
When your Cheltenham basement floods, minutes matter for your drywall, flooring, and belongings. We dispatch a crew immediately, 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 Cheltenham crews assess whether it's a simple seal or a sign of bigger settlement issues before recommending a fix.
Get a Crack Assessment →A tired or undersized sump pump is the #1 reason we get emergency calls in Cheltenham after heavy rain. We install right-sized primary pumps so your basement stays dry even if the power goes out mid-storm.
Schedule a Pump Inspection →An interior drain tile system channels water to a sump pump before it ever reaches your Cheltenham basement floor — one of the most reliable long-term fixes we install.
Ask About Drain Systems →Musty smell upstairs that you can't explain? It's usually the crawl space. Our Cheltenham crews encapsulate the space fully — floor, walls, and vents — so moisture stops migrating into your living areas.
Get a Crawl Space Quote →Commercial properties in Cheltenham 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.

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.
No verbal estimates that change later. What's quoted for your Cheltenham 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.
We quote the job in writing after inspecting it in person, so what you agree to on the phone or at your door is what shows up on the final invoice.
A local dispatch model means the technician who answers questions about your Cheltenham job is the same one who shows up to do it.
If a covered repair fails, we come back and make it right. That's written into every contract, not just promised on the phone.
We'd rather earn a repeat customer with an honest small fix than push a system you don't need.
We can supply the photo documentation and repair scope most Cheltenham, MD carriers ask for before approving a claim.
Every Cheltenham job reflects on the next referral, so we treat each one like it's the only advertising that matters.
"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."
"Insurance claim was a headache until they stepped in with photos and a written scope. Adjuster approved it within a week after that."
