Patient Work Under Historic Homes
Epoxy flooring in Winnetka frequently means a garage or basement under a house by a well-known architect. Wikipedia names George Washington Maher, Walter Burley Griffin, John S. Van Bergen, Howard Van Doren Shaw and David Adler among those who designed homes here. ACS figures summarized by Point2Homes show 48.8% of Winnetka housing was built in 1939 or earlier, so nearly half the garages and basements sit on prewar concrete.
Prewar concrete is different
Older slabs were often poured thinner, finished by hand and laid without a vapor barrier. Over the decades they collect patches, stains and settling cracks. Before suggesting any finish, we grind a test area, take moisture readings in several spots and look at how the floor drains. On some very old floors a breathable sealer is the wiser choice, and we say so.
Lower levels as living space
The median value of owner-occupied homes was $1,091,700 for 2015 to 2019, per Wikipedia. In homes at that level, lower levels are often wine rooms, gyms, playrooms or media rooms. Those spaces suit metallic or solid-color epoxy with a satin topcoat, which looks refined and cleans easily. We test first so the finish lasts.
Garages for collections
With 88.5% of housing units single-family detached, per the ACS summary, many homes have room for a collector car, a golf cart or a workshop. Options we talk through:
- Metallic epoxy for a display garage kept closed most of the day.
- Fine-chip flake that reads almost like a solid color.
- A polyaspartic topcoat to resist hot tire marks.
- Extra thickness under lifts or heavy storage.
A village with a long timeline
Winnetka's first houses went up in 1836, and the village was incorporated in 1869, per Wikipedia. It also has newer homes: 6.3% from the 2000s and 5.9% from the 2010s. New slabs need to cure fully and be ground before coating.
Quiet, clean job sites
On estate properties, neighbors and staff appreciate a tidy crew. We use vacuum-connected grinders to keep dust down and protect driveways and entries while we work.

Winnetka Questions
Can a prewar basement in Winnetka take a metallic epoxy finish?
Sometimes. It depends on moisture readings and the slab's condition. If moisture is too high, we suggest a different finish rather than risk peeling.
How do you keep dust down on a finished property?
We use grinders connected to industrial vacuums and protect entries and driveways while we work.
Can you coat under a car lift?
Yes. We add thickness where the lift posts sit and make sure the slab is sound before coating.
Is a satin finish better than gloss for a lower level?
Many owners prefer satin in living spaces. It shows less glare and fewer footprints.
