Patios & Porches · 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.
Patios & Porches 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 is a heavily wooded town and its patios show it. A shaded slab under mature oaks stays damp long after an open one has dried, and damp plus freeze-thaw is what causes surface scaling and algae. Anti-slip aggregate is standard on shaded slabs, on lakeside steps and on anything sloping toward the water. South-facing and open patios get the UV-stable polyaspartic topcoat so the color holds.
Why we don't install epoxy in Mahtomedi
Most "concrete patio sealer" products at the box store are clear acrylics. They wear off in 12-24 months and offer minimal protection in the meantime. Epoxy is worse: yellows in sunlight within a year, then cracks the first winter. Both products fail on the basic problem: Wisconsin's freeze-thaw cycles demand flexibility and direct UV exposure demands UV-stable chemistry. Polyaspartic delivers both.
If you've been pricing "concrete patio sealers" or "patio epoxy," polyaspartic is the upgrade those terms should resolve to. Higher upfront cost than acrylic ($8-10 / sq ft vs $0.50-1.00 / sq ft for sealer), dramatically longer lifespan, and you're not back at the home center every spring.
Mahtomedi Pricing
Pricing is upfront. Every number includes diamond-ground prep, polyaspartic system, anti-slip aggregate, your color choice, and the lifetime no-yellow warranty. Exterior installs price slightly higher than interior because polyaspartic resin costs more than polyurea + the prep work has to handle weather damage on the slab.

Stoops, steps, and walkways often combine with a patio job for bundled pricing; equipment is already on-site, so adding ~50-100 sq ft of stairs or path runs $400-800 instead of standalone pricing. Send four photos and Dave will text back a real number same-day.
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.
