Halo Water Proofing has been the Willis area's go-to call for Interior Drainage System because we answer the phone, show up on time, and stand behind the work.

One call gets you a straight answer and a real appointment window — not a call-back promise.
📞 +1-866-476-1348Most Willis customers didn't wake up one day with a flooded basement. It usually started small. These are the early signs worth calling about.
Odor is often the first sign Willis customers notice, well before any visible water shows up.
Hairline cracks can widen over a Willis 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.
If your pump is running around the clock instead of only during storms, it's worth having it evaluated before it fails completely.
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 Willis 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 Willis every day.
Storm season in Willis, MI means our emergency line gets busy fast — we triage calls by severity so active flooding at your Willis address jumps the queue ahead of routine inspections.
Call for Emergency Service →Freeze-thaw cycles in Willis, MI push existing cracks wider every winter, which is why we recommend sealing them before they become an active leak rather than after.
Get a Crack Assessment →A tired or undersized sump pump is the #1 reason we get emergency calls in Willis after heavy rain. We install right-sized primary pumps so your basement stays dry even if the power goes out mid-storm.
Schedule a Pump Inspection →Some Willis 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 →A damp, uninsulated crawl space under a Willis home drives up humidity, invites mold, and wastes energy year-round. We seal it with heavy-duty vapor barrier, address any standing moisture, and can add dehumidification if needed.
Get a Crawl Space Quote →Commercial properties in Willis carry bigger stakes when water gets in: inventory, tenants, downtime. We scope commercial jobs with the same crew leads who run our residential work, backed by written specs and timelines.

We start with a phone conversation, not a script — enough to know whether this is an emergency dispatch or a scheduled inspection.
A technician inspects the Willis 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 — the number you approve is the number you're billed.
Our crew completes the work, cleans up the site, and walks you through the warranty coverage on what was installed.
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 Willis job is the same one who shows up to do it.
Our repairs come with written, transferable warranties — a real asset if you sell the Willis property later.
We'd rather earn a repeat customer with an honest small fix than push a system you don't need.
Filing a water damage claim in Willis, MI can be confusing — we've done it enough times with Willis adjusters to help you avoid common denials.
