Halo Water Proofing is a PA-licensed Exterior Waterproofing company that treats every Plymouth job like it's the only one on the schedule.
Every Plymouth technician we send is background-checked and trained on the exact equipment we install — not a subcontractor picked up for the day.

One phone call gets you a straight answer and a real appointment — not a vague callback promise.
📞 +1-866-476-1348Most Plymouth calls didn't start with a flood — they started with one of these small signs weeks or months earlier.
If the basement smells damp no matter the season, water is likely finding a way in somewhere you can't see.
Stair-step cracking in block foundations is one of the most common early signs our Plymouth crews see.
Efflorescence is a reliable early sign that water is moving through your Plymouth foundation wall right now.
If your pump only shuts off for a few minutes at a time, it's worth having it checked before it fails outright.
If a foundation wall looks like it's curving inward, that's beyond a simple patch and needs a real assessment.
These upstairs clues usually show up months after the basement moisture problem actually started.
Whatever's going on with your Plymouth property, chances are we've already fixed something similar nearby this month.
Storm season keeps our Plymouth emergency line busy — active flooding always jumps ahead of routine inspections in the queue.
Get Emergency Help →Not every crack means a structural problem, but every crack deserves a real look. We'll tell you which kind yours is.
Ask About Crack Repair →A failed sump pump is the top reason for emergency calls across Plymouth after heavy rain — we install pumps sized to your actual water volume, plus battery backup for power outages.
Book a Pump Check →For yards fighting bad grading, an exterior French drain intercepts water before it ever touches the foundation wall.
Talk Drainage Options →A damp Plymouth crawl space drives up humidity throughout the house — we seal it completely with heavy-duty vapor barrier and add dehumidification where needed.
Get a Crawl Space Quote →Commercial water intrusion means bigger stakes — inventory, tenants, downtime. We scope commercial Plymouth jobs with written specs and a real timeline.
Request a Commercial Quote →No pressure, no scripts — just what actually happens once you call +1-866-476-1348.

Our trucks are recognizable around Plymouth — we don't cut corners on jobs our neighbors will see.
"Woke up to a wet basement and had someone out by mid-morning. No pressure, no upsell, just fixed it."
"Got three quotes for a crack repair. This was the only company that actually explained why the crack was happening instead of just naming a price."

"Straightforward commercial quote, professional crew, no back and forth."
"Expected a huge bill for three cracks, only one actually needed injection. Appreciated the honesty."
"Insurance claim was stressful until they stepped in with photos and a written scope. Approved within a week."
