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.
We don't run a bidding war between crews. The Andover technician who inspects your property is the same one who does the repair, start to finish.
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.
Stair-step cracking in block foundations is one of the most common early signs our Andover crews see.
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.

Get Emergency Help →We seal active Andover foundation cracks with polyurethane injection — stopping the leak at its source instead of patching the surface.
Ask About Crack Repair →Most Andover pump failures happen during the exact storms that need them most, which is exactly why battery backup matters.

Get a Crawl Space Quote →We handle below-grade waterproofing for Andover property managers and business owners, scheduled around your operating hours to limit disruption.
Request a Commercial Quote →Here's exactly what Andover customers can expect from first call to final walkthrough.
A real technician asks the right questions to understand what's likely happening at your Andover property before anyone drives out.
We point out exactly what we find as we find it, so nothing about the diagnosis feels like a black box.
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.
A local dispatch model means the technician who answers your questions is the same one who shows up.
Our major repairs come with written, transferable warranties — useful if you sell the Andover property later.
If your Andover 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 Andover job reflects on the next referral, so we treat each one like it matters.
"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."
"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 Andover 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.
