From a hairline crack to a fully soaked crawl space, our Larsen crew has seen it and fixed it. No guesswork, no scare tactics — just a clear plan and a fair price.

Halo Water Proofing started small in the Larsen area and grew because customers kept referring us to their neighbors — that's still how most of our work comes in today.
We don't run a bidding war between crews. The Larsen technician who inspects your property is the same one who does the repair, start to finish.
We've worked on foundations from decades-old Larsen 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 Larsen technician today, not an automated queue. We'll explain what's going on and get you scheduled.
📞 +1-866-476-1348Water problems build slowly before they become emergencies. These are the clues our Larsen crews hear about most.
Odor is often the very first clue Larsen homeowners notice, well before any water is visible.
A crack that wasn't there last year is worth a look before it becomes an active leak point.
It's easy to mistake efflorescence for harmless dust, but it actually signals active moisture movement.
A pump under constant strain tends to fail during the exact storm that needs it most.
If a foundation wall looks like it's curving inward, that's beyond a simple patch and needs a real assessment.
Flooring that's cupping near an exterior wall often traces straight back to a basement moisture issue below.
No two Larsen basements are the same — soil type, age of the home, water table. We match the fix to your actual problem.
When water shows up fast, we move fast — extraction, drying equipment, and a plan to stop it from happening again.
Get Emergency Help →Seasonal ground movement in Larsen tends to widen existing cracks over time, so sealing early usually costs less than waiting.
Ask About Crack Repair →Most Larsen pump failures happen during the exact storms that need them most, which is exactly why battery backup matters.
Book a Pump Check →An interior drain tile system routes water to a sump pump before it reaches your Larsen basement floor at all.
Talk Drainage Options →Musty smell upstairs with no obvious source? Check the crawl space first — it's usually the culprit.
Get a Crawl Space Quote →We can phase larger Larsen commercial projects around business hours or tenant schedules so operations keep running.
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 Larsen 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.
If your Larsen basement just needs a small crack seal instead of a full system, that's exactly what we'll tell you.
We photograph the damage and provide a written scope your insurance adjuster can actually use.
Every Larsen job reflects on the next referral, so we treat each one like it matters.
"Woke up to a wet basement and had someone out by mid-morning. No pressure, no upsell, just fixed it."
"Fair price, on time, cleaned up after. Wish every contractor worked this way."
"Crawl space smelled bad for years. After encapsulation, the smell upstairs is completely gone."
"Handled waterproofing for our parking structure with minimal disruption to tenants and stuck to the schedule."
"French drain install took two days exactly as quoted, and the yard looked better than before."
"First contractor who actually explained where the water was coming from instead of just quoting a number."
"Sump pump inspection was thorough and they didn't try to sell me a new one when mine just needed a part replaced."
Every Larsen 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.
