Halo Water Proofing has been the trusted call for Exterior Waterproofing across California because we answer the phone, show up when we say, and stand behind the work.
Background-checked California technicians · Written pricing
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.
Every California technician we send is background-checked and trained on the exact equipment we install — not a subcontractor picked up for the day.
We've worked on foundations from decades-old California 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 California 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 California crews hear about most.
Odor is often the very first clue California 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.
Efflorescence is a reliable early sign that water is moving through your California foundation wall right now.
A pump under constant strain tends to fail during the exact storm that needs it most.
This is one sign we tell California customers never to wait on — wall movement tends to progress, not resolve on its own.
These upstairs clues usually show up months after the basement moisture problem actually started.
Whatever's going on with your California property, chances are we've already fixed something similar nearby this month.
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 California foundation cracks with polyurethane injection — stopping the leak at its source instead of patching the surface.
Ask About Crack Repair →Most California 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 California basement floor at all.

Every California 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."
"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."
"Straightforward commercial quote, professional crew, no back and forth."
"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."
