Basement Waterproofing in Andover, MN That Actually Stops the Water
We diagnose the actual water source before we quote anything — no guessing, no upsell, just a plan sized to your basement.
We diagnose the actual water source before we quote anything — no guessing, no upsell, just a plan sized to your basement.
Basement waterproofing mistakes usually come down to one thing: fixing the symptom instead of the source. A contractor who paints over a wet wall without checking cove joint condition or exterior grading is setting you up for the same call again in a year or two.
We're bonded and insured for both residential and light commercial basement work across Andover, MN.
Most inspection requests get a same-day or next-day appointment, not a two-week wait.
No hourly billing and no change orders once your basement floor is already open.
We use pin-type moisture meters and a flashlight-and-crowbar inspection to trace water back to its real entry point.
We scope every Basement Waterproofing job in person before quoting it, since two properties with the same symptom rarely need the same fix.
We route drain tile beneath the existing slab line so flooring disruption stays minimal during installation.
Battery backup is available for any sump system, so a power outage during a storm doesn't undo the whole fix.
Vertical wall cracks get epoxy or polyurethane injection depending on whether they're still actively weeping.
We install membrane on masonry walls before any insulation or framing goes up, so moisture never gets a chance to reach finished materials.
Poor window well drainage is one of the most overlooked Andover, MN basement leak sources, and it's often the cheapest fix on the list.
You describe what you're seeing — a wet spot, a musty smell, standing water — and we get a rough read on urgency before dispatching anyone.
A technician walks the basement with a moisture meter, checking walls, floor, and cove joints to trace the water back to its actual source.
You'll see drain tile footage, sump specs, and labor broken out separately, not one vague lump-sum number.
You'll get warranty paperwork and a walkthrough of how the system works so you know what to expect going forward.

— Andover Homeowner
"Sump basin was undersized from the last owner's DIY job. They resized it and we haven't had a drop since."
— Andover Customer
"They walked us through exactly why the water was coming in before quoting anything, which no one else had bothered to do."

We keep the cut as narrow as possible and clean up debris before leaving the site.
Larger basements or those needing extensive crack repair can take a bit longer — we'll give you a realistic timeline in the written quote.
Not always — an isolated, non-leaking crack can sometimes be handled with injection alone.
Coverage depends on your policy and the cause of the water intrusion — we can document conditions for a claim, but approval is up to your insurer.
Warranty terms are often transferable if you sell the property later.
