Evanston Epoxy Flooring brings more than 20 years of slab work to epoxy-flooring in Hinsdale, where a commercial job often starts with a question a homeowner never has to ask: which county does this floor sit in? The answer decides who inspects a kitchen floor, so we settle it from the parcel before a proposal goes out.
Residential floors here get the same opening steps as any other job. A diamond grinder or shot blaster opens the slab, because we do not acid etch, and a moisture test is priced as its own line before anything is mixed. The proposal names the product, the system build and the finished thickness, so the floor that goes down can be checked against the paper.
This page is about the floors that answer to someone besides the owner: kitchens, offices and public buildings in a village split between two counties and four townships. We also say up front what a coating will not do. It is a film that follows the concrete under it, so a moving crack stays a moving crack, and we say that before any contract is signed.
A Village Whose Largest Employer Is a Hospital
Hinsdale is a western suburb of Chicago with 17,395 residents at the 2020 census, and its largest employer is a hospital. UChicago Medicine AdventHealth Hinsdale Hospital counts 1,555 employees, and the second name on the list, the high school district, counts 620. Both come up below, though neither has been our customer and we do not present either as one.
Where the hospital sits on the map
The hospital’s address, 120 N. Oak Street, geocodes inside the village in Downers Grove Township, DuPage County. We mention the exact location because it illustrates the larger point of this page: in Hinsdale, a street address does not tell you the county by itself, and the county decides which public health office has a say over a food-service floor.
The commercial floors we quote in a village like this are ordinary ones: break rooms, storage rooms, a shop floor, a small kitchen behind a counter. We price each on the slab in front of us. We have no hospital floor specification in hand, so we never describe a coating as hospital-grade or claim it meets a clinical standard.
Working around hours that do not stop
Commercial jobs in Hinsdale are scheduled around the hours a building has to stay open, not the hours that suit our crew. A kitchen might be ground on a closed day and coated overnight, or a stockroom done in halves so half the shelving stays in use. We set that plan with the owner before we price it, because it changes the labor.
Curing is planned the same way, against slab temperature and the dew point spread at the surface rather than a date on the calendar. If the air in a back room is close to dew point, amine blush can form on a fresh epoxy coat and spoil the bond of the next one, so we measure before we commit to a reopening time.
Downtown and the three Metra stops
Hinsdale’s downtown is a National Register district, and the village has three Metra BNSF stations: Highlands, Hinsdale and West Hinsdale. A storefront or back room in that downtown keeps its own posted hours, and a floor job there needs a plan for deliveries, dust and the equipment trailer around them. We work that plan out on the walk-through, before any number is written down.
Retail floors take foot traffic, carts and the grit tracked in from the street, so a polyaspartic topcoat over a flake or quartz broadcast often suits them better than a single epoxy coat. Polyaspartic also returns a floor to service sooner, which matters to a shop that can close for only a day or two. The proposal states the finished thickness either way.

Two Counties Inside One Village Line, and the Kitchens Between Them
Most of the village, but not all of it, is DuPage
Hinsdale is a village in DuPage County with a small portion in Cook County, and most residents live on the DuPage side. That word most is the one we hold onto. A floor job in the Cook portion is a Cook County matter for public health purposes, and we do not assume which side a building is on from its mailing address.
For a home garage or basement, the county line changes almost nothing about how we work. For a restaurant, a bakery, a school kitchen or any food-service room, it changes who walks in to inspect. The DuPage County Health Department covers the DuPage portion, and the Cook County Department of Public Health covers the Cook portion.
What an inspector looks for at floor level
Illinois adopted the 2022 FDA Food Code as the Illinois Food Code, so a kitchen on either side of the line is held to the same floor rules. Section 6-201.11 asks for floors that are smooth, durable and easily cleanable, with an exception allowing antislip applications for safety. We tune a quartz aggregate broadcast so the floor grips without trapping grease.
Section 6-201.13 covers the joint where floor meets wall: it must be coved and closed, and sealed where a floor is cleaned by water flushing. That is why a kitchen proposal from us lists the cove base as its own item, with height and material named. A flat floor butted against a wall leaves exactly the seam an inspector checks.
Moisture under a kitchen slab
A kitchen is a wet room on concrete whichever health department inspects it, and a slab holding moisture will push it back up through a fresh coating. We run ASTM F1869 calcium chloride tests or ASTM F2170 in-situ relative humidity probes as a priced line, and when the readings call for it, a moisture-mitigation primer goes down before the build coat.
For a kitchen floor, a urethane cement system is often a better fit than 100% solids epoxy, because it tolerates heat, hot-water washdown and more slab moisture. We say which one we are proposing and why, and the warranty exclusions are read aloud before signing, with moisture named first.
Four Townships, One Permit Desk
The village reaches into four townships: Downers Grove, York, Lyons and Proviso. Township lines matter for some local services, but for floor work they do not change who issues the paperwork. The Village of Hinsdale Community Development handles permits, and most residential and commercial projects there take a combination permit.
Whether a floor needs a permit
Whether a floor coating needs a permit on its own is a question for Community Development, not for us to guess at, and the answer can change when the job also adds a drain or alters a commercial kitchen. We ask before quoting anything beyond surface work. When a combination permit applies, the proposal says who pulls it and how it affects the schedule.
Illinois issues no state license for flooring or coatings work, so there is no state license number for us to show. Instead we show whatever contractor license, bond and insurance the Village of Hinsdale asks for. A commercial owner can put those papers in the job file before our crew arrives with the grinder.
Grinding inside the village’s working hours
Diamond grinding and shot blasting are loud work, even with vacuum dust collection running. We plan them inside the construction hours the village allows, so a one-day garage job does not run into a neighbor’s evening. In a village where 89.9 percent of occupied homes are owner-occupied, most of the people next door own the house they live in.
Home jobs carry the paperwork the Illinois Home Repair and Remodeling Act requires: a written contract and the Home Repair: Know Your Consumer Rights pamphlet, both before work starts. Cracks, old paint and any failed coating are read before the quote, and if a slab needs repair first, we say so plainly.
Schools and Public Buildings: District 86 and the Lodge
The high school district
Hinsdale Township High School District 86, the village’s second-largest employer, runs Hinsdale Central High School. A public district buys floor work through its own process, on its own specifications and its own calendar, and we do not claim District 86 as a customer or describe any of its floors as our work.
When a public body puts floor work out, its specification decides the system, not us. What we can answer is what such a document tends to ask about: the product, the system build, the finished thickness and the moisture test. Our proposals already name those, so a facilities office reading one can compare it line by line with its own requirements.
The Katherine Legge Memorial Lodge
The Katherine Legge Memorial Lodge was built in 1927 and donated to the village in 1973, which makes it a public building with nearly a century of use behind it. We have no record of its floors and say nothing about them. What the lodge illustrates is the kind of older building where we read the old coating before quoting anything.
On a concrete floor that has carried decades of paint, sealer and patching, a fresh coat over the top is a gamble. We test how the existing film is bonded, grind through what will not hold, and flag any crack that needs repair first. Old paint over a slab can also hide efflorescence, the white salt deposit that tells us moisture has been moving through the concrete for years.
Floors at home, on either side of the line
Beyond kitchens and public buildings, most floors in the village sit under houses. Hinsdale counts 4,465 owner-occupied single-family detached homes, and their garages and basements are the everyday side of our work. For those floors the county line changes nothing; the slab decides the system through its moisture, its old coatings and how its cracks are behaving.
Basement slabs in Hinsdale get the same priced moisture line as a kitchen, starting with an ASTM D4263 plastic sheet test as a first read and moving to probes when the sheet shows trouble. A floor drain or sump pit is detailed so the coating ends cleanly at its edge rather than lifting there. If readings run too high for any warranty we would honor, we say so.
Two Illinois rules travel with every Hinsdale job. Floor coatings are chosen within the VOC limits in 35 Ill. Adm. Code Part 223 Subpart C, which bind the installer as well as the manufacturer. And we never sell an epoxy floor as radon reduction, because in Illinois that work requires an IEMA radon mitigation license.
