Foundation leaking? Basement smells off? Halo Water Proofing sends a real technician to your Andover property, gives you a straight answer, and fixes it right the first time.
Free, no-obligation estimates · 24/7 dispatch
Halo Water Proofing started small in the Andover area and grew because customers kept referring us to their neighbors — that's still how most of our work comes in today.
Our Andover crew leads have handled repairs like yours dozens of times before, and a supervisor signs off before we call any job finished.
We've worked on foundations from decades-old Andover 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 Andover technician today, not an automated queue. We'll explain what's going on and get you scheduled.
📞 +1-866-476-1348Most Andover calls didn't start with a flood — they started with one of these small signs weeks or months earlier.
Odor is often the very first clue Andover 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.
That white powder on basement walls is mineral residue left behind as water passes through the concrete.
If your pump only shuts off for a few minutes at a time, it's worth having it checked before it fails outright.
If a foundation wall looks like it's curving inward, that's beyond a simple patch and needs a real assessment.
Peeling paint near the floor upstairs is one of the last signs Andover homeowners connect to a basement problem.
No two Andover basements are the same — soil type, age of the home, water table. We match the fix to your actual problem.
A flooded Andover basement doesn't wait for morning, and neither do we. Our crews extract it fast and start drying the space the same visit.
Get Emergency Help →We seal active Andover foundation cracks with hydraulic cement injection — stopping the leak at its source instead of patching the surface.
Ask About Crack Repair →Already have a pump that's struggling? We'll test it honestly and tell you whether it needs replacing or just a tune-up.
Book a Pump Check →Some Andover properties need both systems working together — we'll say so honestly instead of selling just one.
Talk Drainage Options →A damp Andover crawl space drives up humidity throughout the house — we seal it completely with heavy-duty vapor barrier and add dehumidification where needed.
Get a Crawl Space Quote →We can phase larger Andover 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.
Every Andover quote is written before work starts, not estimated verbally and adjusted later.
Once the job's done, you get written proof of what was installed and exactly what the warranty covers.
We've heard every Andover horror story about contractors who disappear mid-job or pad the invoice. Here's how we do it differently.
We quote the job in writing after seeing it in person, so there's no surprise on the final invoice.
Our crews stage locally near Andover, which is why most emergency calls get a technician on-site in under two hours.
Our major repairs come with written, transferable warranties — useful if you sell the Andover property later.
Our technicians are trained to diagnose accurately, not to upsell — that changes the advice you actually get.
We photograph the damage and provide a written scope your insurance adjuster can actually use.
Word of mouth is still how most Andover customers find us, which keeps our standards high.
"Called during a storm and had a tech at my door within two hours. Explained everything before touching anything — basement's been dry since."
"Fair price, on time, cleaned up after. Wish every contractor worked this way."
"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."
"Insurance claim was stressful until they stepped in with photos and a written scope. Approved within a week."
"Crew was respectful of our landscaping during the drain install and left the yard looking better than before they started."
We back our Andover work with real, transferable warranties because we plan to be here long after the job is done, not just for the one visit.
