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

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

Every technician on our Sellersville 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 Sellersville customers didn't wake up one day with a flooded basement. It usually started small. These are the early signs worth calling about.
If the basement smells damp even when it looks dry, moisture is likely moving through the walls or floor somewhere.
Hairline cracks can widen over a Sellersville winter's freeze-thaw cycle and become active leak points by spring.
That white chalky film on basement walls is efflorescence — mineral deposits left behind as water evaporates through concrete.
If your pump is running around the clock instead of only during storms, it's worth having it evaluated before it fails completely.
This is one sign we tell Sellersville customers not to wait on — wall movement tends to progress rather than resolve on its own.
These signs upstairs are often the last clue Sellersville homeowners notice, even though the moisture issue started in the basement months earlier.
Every Sellersville 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 Sellersville 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 →Hairline cracks are how most Sellersville basements start leaking. We use hydraulic cement injection to seal the crack from the inside out, stopping the leak at the source instead of just painting over the symptom.
Get a Crack Assessment →Most sump pump failures we see in Sellersville happen during the exact storms that need them most — a battery backup closes that gap when the power drops.
Schedule a Pump Inspection →An interior drain tile system channels water to a sump pump before it ever reaches your Sellersville basement floor — one of the most reliable long-term fixes we install.
Ask About Drain Systems →Older Sellersville homes with vented crawl spaces are especially prone to seasonal moisture swings — encapsulation closes that off for good.

Every Sellersville job reflects on the next referral, so we treat each one like it's the only advertising that matters.
"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."
"Got quotes from three companies for a crack repair. These guys were the only ones who actually explained why the crack was happening instead of just quoting a price."
"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."
"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."
