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

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

Every technician on our Newtown Square 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 Newtown Square customers didn't wake up one day with a flooded basement. It usually started small. These are the early signs worth calling about.
A musty smell in the basement or crawl space is usually moisture you can't see yet, not just "old house smell."
Even small cracks are worth a second look — they rarely stay small once seasonal ground movement gets involved.
That white chalky film on basement walls is efflorescence — mineral deposits left behind as water evaporates through concrete.
A pump under constant strain tends to fail at the worst possible time — usually during the next big Newtown Square storm.
A bowing basement wall is a structural concern in addition to a water one — this is the kind of Newtown Square call we prioritize fast.
Peeling paint low on a basement wall or warped baseboards upstairs often trace back to moisture migrating up from below.
Every Newtown Square property is different — soil, slope, foundation age, water table depth. We size the fix to the actual problem, not a one-size package.
Standing water in your basement doesn't wait for business hours, and neither do we. Our Newtown Square emergency crews extract standing water first, then diagnose where it's getting in so it doesn't happen again next storm.
Call for Emergency Service →Hairline cracks are how most Newtown Square basements start leaking. We use polyurethane injection to seal the crack from the inside out, stopping the leak at the source instead of just painting over the symptom.

Schedule a Pump Inspection →Some Newtown Square lots need both an interior and exterior system working together — we'll tell you honestly if that's the case rather than selling just one.
Ask About Drain Systems →Musty smell upstairs that you can't explain? It's usually the crawl space. Our Newtown Square crews encapsulate the space fully — floor, walls, and vents — so moisture stops migrating into your living areas.
