What We Do
Coatings built for Tri-Cities concrete
Daily-driver garage, finished basement, or a working shop floor — we match the system to your concrete and how the space gets used.
Garage Floor Epoxy
Full-flake epoxy systems that shrug off hot tires, dropped tools, and the road salt a Tri-Cities winter tracks in. Diamond-ground and sealed to last well past a decade.

Polyaspartic Coatings
A polyaspartic topcoat cures fast and stays UV-stable — no ambering near the garage door. The tougher, quicker-turnaround upgrade over a standard epoxy build.
Learn more →
Metallic Epoxy Floors
Hand-worked metallic pigment floors with a marbled, three-dimensional finish — the decorative tier for finished basements, showrooms, and display garages.
Learn more →
Commercial & Industrial
Chemical- and abrasion-resistant coatings for shops, warehouses, and commercial kitchens across the Tri-Cities, with slip-resistant additives where footing matters.
Learn more →
Concrete Repair & Prep
Crack repair, joint filling, and full diamond grinding before any coating goes down. On older Johnson City and Kingsport slabs, the prep is most of the job.

Why a Tri-Cities epoxy floor is its own kind of install
The Tri-Cities sits up in the mountains of upper East Tennessee — higher and colder than Knoxville or Chattanooga — and that elevation changes what a concrete coating has to survive. Here is what a Johnson City, Kingsport, or Bristol floor actually needs.
The short version: Johnson City sits near 1,600 feet of elevation. Every extra freeze-thaw cycle that elevation brings is another cycle of road salt and water working its way into bare concrete — which is exactly what a properly prepped coating is there to stop.
What the Tri-Cities climate does to a coated floor
Johnson City sits around 1,600 feet of elevation, with the surrounding ridgelines well above that. Compared with lower East Tennessee, that means colder winters and noticeably more freeze-thaw cycling — the slow expansion and contraction that works moisture and road salt deeper into bare concrete with every cycle.
Freeze-thaw and road salt. On an uncoated garage slab, that cycling shows up as surface spalling and pop-outs — usually starting at the garage-door edge where snowmelt and de-icer collect. A properly prepared coating seals the concrete off from chloride and water entirely, which is the whole point of coating a Tri-Cities floor rather than just painting it. But that only holds if the surface is ground and repaired correctly first.
Humidity and moisture testing. Tri-Cities summers are still humid, and concrete slabs constantly exchange moisture with the ground beneath them. A slab pushing too much vapor will blister a coating from underneath within a year or two. That is why any installer worth hiring runs a calcium chloride or relative-humidity test before quoting a system — and specifies a vapor-mitigating primer on slabs that fail the threshold.
Install windows. Spring and fall are the easiest seasons to coat a floor here — mild slab temperatures, manageable humidity. Mid-winter installs are still doable, but they lean on polyaspartic systems, which cure across a wider temperature range than standard epoxy.
Concrete across Johnson City, Kingsport, and Bristol
The three cities have very different histories, and the concrete reflects it.
- Johnson City. Housing ranges from the early-1900s homes of the Tree Streets historic district through decades of mid-century neighborhoods to newer construction out toward Boones Creek and Gray. Older slabs typically need real crack and joint repair before coating; newer subdivision slabs are usually sound and go straight to grinding.
- Kingsport. Kingsport was laid out in the 1910s as one of America's first thoroughly planned industrial cities, built around the Eastman chemical works. That legacy left a lot of solidly built mid-century planned housing, alongside newer growth — a mix of slab eras worth assessing in person.
- Bristol. Bristol's older housing stock straddles the Tennessee-Virginia state line, and slab condition varies widely block to block. An on-site look is the only honest way to price a Bristol floor.
- Detached garages and basements. Detached garages across the Tri-Cities often show more wear — less conditioning, more exposure. Finished basements run higher year-round humidity and almost always need a vapor-mitigating primer under the coating.
What goes on that concrete varies by space: the finished basements and display garages are where metallic epoxy floors in Johnson City get specified, while the shop, warehouse, and kitchen work runs through our commercial epoxy flooring systems.
How to compare Tri-Cities epoxy contractors
Floor coating is light-touch work to sell and hard work to do right, so the quotes you get will vary more than the prices suggest — it helps to walk in knowing the going epoxy flooring cost in Johnson City, which our guide breaks down by system type and garage size. A few questions sort the real installers from the rest:
- Do you diamond-grind or acid-etch? Diamond grinding is the right answer. Etching is the shortcut that fails years sooner.
- What manufacturer system do you install? Real systems come from established manufacturer-backed product lines with documented warranties — not unnamed “generic epoxy.”
- Are you Tennessee-licensed for the project size? Tennessee requires a Home Improvement License for projects from $3,000 to $25,000, and a full contractor license above that. Verify any contractor at the Tennessee state verification portal.
- Do you moisture-test the slab before quoting? In this climate, the right answer is yes.
- Is the quote itemized? Prep, repair, and coating should be separate lines — hidden prep is where bad jobs hide.
On every install we run across Johnson City and the Tri-Cities, we diamond-grind the floor, install a manufacturer-backed system, moisture-test the slab, and quote in writing — itemized, with the coating system and the prep method named in writing.

Common Questions
Tri-Cities Epoxy Flooring FAQs
How much does epoxy flooring cost in Johnson City? +
Most professionally installed epoxy and concrete coating floors in the Tri-Cities run $4 to $16 per square foot, depending on the coating system — a typical 2-car garage lands roughly $1,800 to $8,000. Slab condition moves the number.
How long does an installation take? +
A standard 1- or 2-car garage is usually a one-day install for a polyaspartic or hybrid system, and one to two days for a full epoxy build or a metallic floor. Concrete that needs real crack or joint repair adds time before any coating goes down.
Will an epoxy floor hold up to Tri-Cities winters? +
Yes — when it's prepped correctly. The Tri-Cities sees more freeze-thaw cycling than lower East Tennessee because of the elevation, and that drives road salt and moisture into bare concrete. A properly ground, repaired, and coated slab is sealed off from all of it. The key is the prep, not the coating brand.
What is the difference between epoxy and polyaspartic? +
Epoxy is a proven, cost-effective resin that cures slowly and can amber under UV light over the years. Polyaspartic cures far faster — often a one-day install — stays UV-stable, and resists abrasion and chemicals better. It costs roughly 30 to 50 percent more. Many Tri-Cities garages use a hybrid: an epoxy basecoat with a polyaspartic topcoat.
Can you coat an older Johnson City garage slab? +
Almost always, yes. Older slabs — common in Johnson City's established neighborhoods — show cracks, worn joints, and surface pitting, and all of that is repaired during prep. The honest exceptions are a slab with active structural movement or unresolved moisture from below; an on-site inspection confirms which situation you have.
Do you diamond-grind the concrete or acid-etch it? +
Diamond grinding, every floor. Grinding mechanically opens the concrete so the coating bonds into it. Acid etching is the budget shortcut, and it's the most common reason coatings — especially DIY-kit floors — peel within a few years. A quote that doesn't mention grinding is a quote to question.
Is an epoxy floor slippery when wet? +
A clean, dry coated floor grips about like finished concrete. Wet, any smooth coating is more slippery. For garages where snowmelt or wet shoes are a concern, a fine anti-slip additive is broadcast into the topcoat — nearly invisible, but it adds real traction underfoot.
Do you serve Kingsport and Bristol too? +
Yes. We cover the full Tri-Cities — Johnson City, Kingsport, and Bristol — plus Jonesborough, Elizabethton, Gray, and the surrounding Northeast Tennessee communities. Tell us where the project is when you reach out.
