Exterior membrane systems, footing drains, and corrected grading tackle Forest Lake, MN water intrusion at the source, before it ever reaches the interior wall.
A lot of Forest Lake, MN exterior waterproofing failures trace back to a footing drain that was installed without proper slope, which means it never actually moved water the way it was supposed to. We verify slope during installation, not just at design.
Exterior work involves excavation near the foundation, and every crew member is trained and insured for that specific scope.
Excavation equipment and membrane materials are staged locally so an exterior project doesn't wait on out-of-town logistics.
Pricing is quoted per linear foot of foundation wall being treated, based on an on-site measurement, not a phone estimate.
We install dimpled membrane rated for below-grade use, paired with a footing drain that ties into your existing or new drainage system.
Every Forest Lake, MN Exterior Waterproofing job starts with an inspection, not a generic package — here's what that typically includes.
We excavate to the footing, apply a dimpled waterproof membrane directly to the foundation wall, and backfill with proper drainage material.
We slope footing drains correctly during installation, since a flat or reverse-sloped drain simply won't move water.
We regrade the perimeter to direct surface water away from the wall, typically paired with downspout extensions.
We also inspect and reseal the window frame itself while the well is open.
Downspouts discharging within a few feet of the foundation send roof water directly toward the problem — we extend them well clear of the wall.
Photos of the exterior foundation area help us plan equipment and access before the visit.
A technician walks the exterior perimeter, checks grading slope, and identifies where excavation would be needed for a membrane or footing drain fix.
You'll see linear footage, membrane type, and footing drain scope broken out with pricing before any digging starts.
We restore grading and any disturbed landscaping as the final step before calling the job complete.

"They found our downspouts were dumping water two feet from the foundation. Extended them and regraded, and that alone made a noticeable difference."
— Forest Lake Customer

— Forest Lake Homeowner
"Fast turnaround given how much digging was involved."

We'll recommend the right approach based on what the inspection actually finds.
Some disruption is unavoidable near the foundation, but we restore grading and replant where reasonable as part of the scope.
Excavation typically goes down to the footing, which varies by home but is often four to eight feet depending on foundation depth.
We'll walk through both options and their trade-offs so you can make an informed choice.
Yes — grading correction and downspout extension are often standalone fixes that resolve a surprising number of Forest Lake, MN water intrusion issues on their own.
