Interior waterproofing is a permanent system installed from inside your basement. We seal your foundation walls and the wall–floor joint, add a wall vapor barrier, and pair it with a sump pump and battery backup. Unlike DIY paint-on coatings, it seals water out at the source instead of just hiding the symptoms.
Our clay-heavy soil, deep winter frost, and heavy spring snowmelt put constant water pressure against foundation walls. That water pressure forces water through gaps and the wall–floor joint — which professional sealing stops permanently.
Common warning signs are water or dampness on the floor after rain, a musty smell, white chalky residue (efflorescence) on the walls, mold, or gaps in the foundation. If you notice any of these, a free inspection will tell you exactly what is happening and what it will take to fix it.
For most Wisconsin homes, interior sealing is the most reliable and cost-effective permanent fix. It's installed from inside, works with our soil and frost conditions, and doesn't require excavating your yard. We'll tell you honestly if your situation calls for something else.
Every basement is different, so we give you a fixed, written quote after a free in-person inspection — no surprises and no obligation. Most interior sealing systems fall within a predictable range, and we offer financing to spread the cost into low monthly payments.
