We diagnose the actual water source before we quote anything — no guessing, no upsell, just a plan sized to your basement.
We've seen enough Andover, MN basements to know that a wet spot in one corner rarely tells the whole story. Before we recommend drain tile or a sump upgrade, we trace the water back to where it's actually entering, not just where you noticed it.
Every technician carries full state licensing and liability coverage before they ever step into your basement.
Our Andover, MN crews are staffed locally, so a wet basement call doesn't sit in a national queue for a week.
You get one written number before drilling starts, covering drain tile, sump basin, and discharge line.
Thermal imaging helps us confirm whether a stain is active moisture or an old, already-fixed leak.
Every Andover, MN Basement Waterproofing job starts with an inspection, not a generic package — here's what that typically includes.
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.
The cove joint where the floor meets the foundation wall is one of the most common Andover, MN leak points, and we seal it as part of every interior system.
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.
We explain the reasoning behind the recommended system so you know exactly what you're paying for and why.
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
"Appreciated that the estimate matched the final invoice exactly — no surprise add-ons once the floor was already open."
— Andover Homeowner
"Installed a battery backup sump pump for us right before a big storm season — glad we did it when we did."
— Andover Customer
Cost depends on linear footage, sump basin size, and whether cove joint sealing is included — we won't give a number without an in-person inspection.
Yes — interior drain tile requires cutting a channel along the slab edge, which we patch with concrete once the system is installed.
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.
We provide photos and moisture readings that many Andover, MN homeowners have used to support a claim.
Warranty terms are often transferable if you sell the property later.
