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

Halo Water Proofing started as a small WI crew and grew because Greenfield customers kept referring us to neighbors — that's still how most of our work comes in today.

We don't send apprentices to figure it out on your dime. Every Greenfield 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 — not a call-back promise.
📞 +1-866-476-1348Water problems rarely announce themselves all at once — they usually show up as small clues first. Here's what our Greenfield technicians hear about most often before an inspection.
Odor is often the first sign Greenfield customers notice, well before any visible water shows up.
Hairline cracks can widen over a Greenfield winter's freeze-thaw cycle and become active leak points by spring.
Efflorescence is a clear sign that water is actively passing through your Greenfield foundation wall, even if you've never seen standing water.
A sump pump that never stops cycling is often working harder than it should, or is undersized for your Greenfield lot's water table.
This is one sign we tell Greenfield customers not to wait on — wall movement tends to progress rather than resolve on its own.
These signs upstairs are often the last clue Greenfield homeowners notice, even though the moisture issue started in the basement months earlier.
From an emergency pump swap at 2 a.m. to a full exterior drainage system, this is the work we do in Greenfield every day.
Standing water in your basement doesn't wait for business hours, and neither do we. Our Greenfield emergency crews pump out the basement first, then diagnose the source so it doesn't happen again next storm.
Call for Emergency Service →Hairline cracks are how most Greenfield basements start leaking. We use polyurethane 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 →A tired or undersized sump pump is the #1 reason we get emergency calls in Greenfield after heavy rain. We install battery backup units so your basement stays dry even if the power goes out mid-storm.
Schedule a Pump Inspection →For Greenfield properties fighting grading or drainage issues, an exterior French drain can intercept water before it ever reaches the foundation wall at all. We map your yard's slope and water flow before recommending which approach fits.
Ask About Drain Systems →Musty smell upstairs that you can't explain? It's usually the crawl space. Our Greenfield crews encapsulate the space fully — floor, walls, and vents — so moisture stops migrating into your living areas.
Get a Crawl Space Quote →Commercial properties in Greenfield 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.
Request a Commercial Quote →No confusing steps, no hard sell — just the same process our Greenfield crews follow on every job.
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 Greenfield property in person, checking the foundation, drainage, grading, and any active moisture before recommending a fix.
No verbal estimates that change later. What's quoted for your Greenfield job is what's invoiced.
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.
Our trucks stage locally around Greenfield, which is why emergency calls typically get a technician on-site in under two hours, not "sometime tomorrow."
Our repairs come with written, transferable warranties — a real asset if you sell the Greenfield property later.
If your Greenfield basement just needs a $200 crack seal instead of a $12,000 system, that's what we'll tell you.
We can supply the photo documentation and repair scope most Greenfield, WI carriers ask for before approving a claim.
Every Greenfield job reflects on the next referral, so we treat each one like it's the only advertising that matters.
"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."
"Got quotes from three companies for a crack repair. These guys were the only ones who actually explained why the crack was happening instead of just quoting a price."
"Our old sump pump died during the worst storm of the year, obviously. They had a battery backup system installed within a day. Haven't worried about it since."
"Managed our building's parking garage waterproofing project. Kept to the schedule, communicated well with tenants, minimal disruption."
"French drain install took two days like they said it would, not five. Yard was put back together better than before."
"Insurance claim was a headache until they stepped in with photos and a written scope. Adjuster approved it within a week after that."
Whether you're in the older, established parts of Greenfield or a newer subdivision still settling, our crews have likely already worked on a foundation like yours nearby.
