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

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

We don't send apprentices to figure it out on your dime. Every Plymouth job is run by a technician who has done this exact repair dozens of times, with a supervisor who signs off before we call it finished.
One call gets you a straight answer and a real appointment window β not a call-back promise.
π +1-866-476-1348Water problems rarely announce themselves all at once β they usually show up as small clues first. Here's what our Plymouth technicians hear about most often before an inspection.
A musty smell in the basement or crawl space is usually moisture you can't see yet, not just "old house smell."
Hairline cracks can widen over a Plymouth winter's freeze-thaw cycle and become active leak points by spring.
It's easy to dismiss efflorescence as harmless dust, but it actually signals active moisture movement through the wall.
A pump under constant strain tends to fail at the worst possible time β usually during the next big Plymouth storm.
If a foundation wall looks like it's leaning or bulging inward, that's beyond a simple seal and needs a full assessment.
Flooring that's cupping or warping near an exterior wall is a common clue our Plymouth crews trace back to a drainage issue.
From an emergency pump swap at 2 a.m. to a full exterior drainage system, this is the work we do in Plymouth every day.
When your Plymouth basement floods, minutes matter for your drywall, flooring, and belongings. We dispatch a crew around the clock, pull the water, and start drying the space with commercial-grade equipment the same visit.
Call for Emergency Service βHairline cracks are how most Plymouth 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 βAlready have a sump pump that's failing or too small for your Plymouth lot? We'll test it, tell you honestly whether it needs replacing, and size the new one to your actual water volume β not the cheapest unit on the truck.
Schedule a Pump Inspection βAn interior drain tile system channels water to a sump pump before it ever reaches your Plymouth basement floor β one of the most reliable long-term fixes we install.
Ask About Drain Systems βMusty smell upstairs that you can't explain? It's usually the crawl space. Our Plymouth crews encapsulate the space fully β floor, walls, and vents β so moisture stops migrating into your living areas.
Get a Crawl Space Quote βWe can phase larger Plymouth commercial projects around business hours or tenant schedules so operations aren't disrupted mid-project.

We start with a phone conversation, not a script β enough to know whether this is an emergency dispatch or a scheduled inspection.
A technician inspects the Plymouth property in person, checking the foundation, drainage, grading, and any active moisture before recommending a fix.
You receive a written, itemized quote before any work begins β the number you approve is the number you're billed.
Once the repair is done, you get documentation of the work and a written warranty β not just a handshake.
We quote the job in writing after inspecting it in person, so what you agree to on the phone or at your door is what shows up on the final invoice.
A local dispatch model means the technician who answers questions about your Plymouth job is the same one who shows up to do it.
If a covered repair fails, we come back and make it right. That's written into every contract, not just promised on the phone.
If your Plymouth basement just needs a $200 crack seal instead of a $12,000 system, that's what we'll tell you.
Filing a water damage claim in Plymouth, MN can be confusing β we've done it enough times with Plymouth adjusters to help you avoid common denials.
