From a hairline foundation crack to a fully flooded crawl space, Halo Water Proofing has handled it in Westmont 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 Westmont customers kept referring us to neighbors — that's still how most of our work comes in today.

Every technician on our Westmont 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.
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.
📞 +1-866-476-1348Most Westmont 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."
Stair-step cracks in block foundations are a common early warning sign we see across Westmont-area homes.
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.
A bowing basement wall is a structural concern in addition to a water one — this is the kind of Westmont call we prioritize fast.
Flooring that's cupping or warping near an exterior wall is a common clue our Westmont crews trace back to a drainage issue.
Every Westmont property is different — soil, slope, foundation age, water table depth. We size the fix to the actual problem, not a one-size package.
Storm season in Westmont, PA means our emergency line gets busy fast — we triage calls by severity so active flooding at your Westmont address jumps the queue ahead of routine inspections.
Call for Emergency Service →Freeze-thaw cycles in Westmont, PA push existing cracks wider every winter, which is why we recommend sealing them before they become an active leak rather than after.

"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."
