Basement Floor Coatings · Mahtomedi, MN · Est. 2003
Mahtomedi sits on the east shore of White Bear Lake in Washington County, with the small villages of Willernie and Birchwood tucked in beside it. It was resort country before it was a suburb, reached from St. Paul by streetcar, and the Wildwood amusement park stood at the south end of town until the 1930s. We install polyurea + polyaspartic floor coatings for Mahtomedi homeowners: diamond-ground prep, custom flake colors, 1–2 day install, written 15-year warranty. Three layers. Summer cottages from the 1900s through the 1930s along the lake and through the Old Village and Wildwood, winterized and added onto over the decades; a 1950s through 1970s ring behind them; and larger newer homes on the east side toward Highway 244 and the Dellwood line.
Basement Floor Coatings in Mahtomedi
Mahtomedi is a resort town that became a suburb, and the concrete carries both histories. Through the Old Village and Wildwood and along the east shore, houses began as summer cottages between the 1900s and the 1930s and were winterized later, so the garage is often detached, unheated, and standing on a slab poured decades after the house it serves. Those slabs vary more than anything else we work on, because there was no single era or standard behind them. Behind that band, the 1950s through 1970s ring is conventional suburban housing with attached two-car garages that grind and coat predictably, and the newer building on the east side toward Highway 244 has modern slabs. Two things tie the lake side of town together: the water table, which is high within a few blocks of White Bear Lake and makes a moisture test worth doing before any lower-level floor is quoted, and the tree cover, which keeps outdoor slabs damp and is why anti-slip aggregate goes on nearly every patio and step here.
Mahtomedi basements near White Bear Lake are the ones in this city most likely to need vapor mitigation, and the reason is how close the water table is. Every lakeside basement and walkout gets a calcium chloride test before it is quoted. Homes further back in the 1950s to 1970s ring and up the hill toward Highway 244 usually test clean and take standard polyurea over a straightforward grind.
Why we don't install epoxy in Mahtomedi
Basements are the worst environment for an epoxy floor coating. Three reasons compound: moisture transmits through below-grade slabs constantly (epoxy is moisture-intolerant and delaminates), VOCs are a real concern in enclosed basement spaces with limited ventilation (epoxy off-gasses for days), and basements settle and shift over decades of freeze-thaw (rigid epoxy cracks). Polyurea fixes all three. Here's the side-by-side:
If you've been searching for "basement floor sealer" or "basement epoxy," polyurea is what those terms should resolve to. Same flake colors. Same approximate price as a contractor-grade epoxy install. Vastly better suited to a basement.

The 6-step install
Same checklist on every floor. The reason our coatings still look new at year ten when the cheap stuff peeled in year two.
