From a hairline crack to a fully soaked crawl space, our Plymouth crew has seen it and fixed it. No guesswork, no scare tactics — just a clear plan and a fair price.
Licensed & insured in MN · Real warranties
We built Halo Water Proofing around a simple promise: show up when we say, tell you the truth about what's wrong, and fix it so it stays fixed.
Our Plymouth crew leads have handled repairs like yours dozens of times before, and a supervisor signs off before we call any job finished.
We've worked on foundations from decades-old Plymouth homes to brand-new builds still settling into their soil, so whatever your basement is dealing with, we've likely seen a version of it nearby.
Talk to a real Plymouth technician today, not an automated queue. We'll explain what's going on and get you scheduled.
📞 +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.
Small cracks in a Plymouth foundation rarely stay small — seasonal ground movement tends to widen them over time.
Efflorescence is a reliable early sign that water is moving through your Plymouth foundation wall right now.
A pump under constant strain tends to fail during the exact storm that needs it most.
A wall that's starting to bow is a structural issue on top of a water issue — this jumps to the front of our Plymouth schedule.
These upstairs clues usually show up months after the basement moisture problem actually started.
From a 2 a.m. sump pump failure to a planned exterior drainage project, here's what our Plymouth crews handle most.
When water shows up fast, we move fast — extraction, drying equipment, and a plan to stop it from happening again.
Get Emergency Help →We seal active Plymouth foundation cracks with hydraulic cement injection — stopping the leak at its source instead of patching the surface.
Ask About Crack Repair →Most Plymouth pump failures happen during the exact storms that need them most, which is exactly why battery backup matters.
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 →Older Plymouth homes with vented crawl spaces see the biggest swings in seasonal humidity — encapsulation closes that off for good.
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.
You'll talk to a person, not a script — enough of a conversation to know what to expect before anyone shows up.
No jargon, no pressure — just a clear look at what's actually going on.
The number you approve is the number you're billed — no change orders once the crew shows up.
Once the job's done, you get written proof of what was installed and exactly what the warranty covers.
We've heard every Plymouth horror story about contractors who disappear mid-job or pad the invoice. Here's how we do it differently.
You get a real number before any work starts — what you approve is what you're billed.
A local dispatch model means the technician who answers your questions is the same one who shows up.
Warranty terms are explained in plain language before you sign, with no fine-print surprises later.
We'd rather earn a repeat Plymouth customer with an honest fix than push a system you don't need.
We photograph the damage and provide a written scope your insurance adjuster can actually use.
Word of mouth is still how most Plymouth customers find us, which keeps our standards high.
"Called during a storm and had a tech at my door within two hours. Explained everything before touching anything — basement's been dry since."
"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."
"Our sump pump died during the worst storm of the year, obviously. Battery backup was installed the next day and we haven't worried since."
"Handled waterproofing for our parking structure with minimal disruption to tenants and stuck to the schedule."
"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."
"Sump pump inspection was thorough and they didn't try to sell me a new one when mine just needed a part replaced."
Every Plymouth technician we send is background-checked and trained on the systems we install, so the crew that inspects your property is the same one that fixes it.
