Epoxy Flooring in Sioux Falls, SD

Sioux Falls is where we do the most epoxy flooring, and it is a city that keeps adding garages. The 2020 census counted 192,517 people. The Census Bureau's estimate for July 2025 is 213,748, a gain of more than 21,000 in about five years. Each new block brings attached garages with fresh slabs, and each older block has floors that have been through dozens of winters. We coat both.

A city of owners, renters and long stays

Census QuickFacts puts the owner-occupied rate at 59.5% for 2020 to 2024. The median owner-occupied home is valued at $292,400, and 84.8% of residents lived in the same house a year earlier. Those numbers shape the calls we get:

• Owners staying put want a garage floor coating that holds up for years, usually a flake system with a clear topcoat.
• Owners getting ready to sell want a clean, finished garage and basement that photograph well.
• Landlords want a sealed basement or garage they can mop out between tenants. The 2020 census showed an 8.4% rental vacancy rate, so turnover is part of owning rentals here.

Below zero, not just below freezing

Road salt gets most of the attention, and it matters. What surprises people who move here is the deep cold. Wikipedia's climate data for the city shows about 25 nights a year at or below 0°F. On those nights an unheated garage slab can sit far below the temperature most epoxy needs to cure. That affects two things:

• When we install. A coating put on a slab that is too cold can stay soft or cure cloudy. We measure slab temperature on install day, and from late fall to early spring we lean on polyaspartic systems or a heated space.
• How the floor behaves in January. A car parked in from a below-zero street sheds ice chunks that melt into brine under the tires. Flake texture gives boots something to grip when that brine is on the floor.

One city, two counties

Sioux Falls sits mostly in Minnehaha County and extends south into northern Lincoln County. The city also absorbed the neighboring city of South Sioux Falls in 1955, which had nearly 1,600 residents at the time. So a single Sioux Falls ZIP can hold a 1950s house with a narrow detached garage and, a mile away, a three-stall attached garage poured in the last few years. Here is how we usually approach each:

• Older garages often have oil soaked deep into the concrete, old paint, and patches from past repairs. We grind until we reach clean concrete, fill cracks and pits, and may use a thicker base coat to level low spots.
• Newer garages usually have sound, flat slabs. Their surface is often too smooth for a coating to grab, so grinding is still the first step.
• Finished basements in both eras get a moisture test first, then basement floor epoxy or a metallic finish.

Shop and commercial floors

The city's biggest employers are health systems. Wikipedia lists Sanford Health at 11,010 employees and Avera Health at 7,888, with Smithfield Foods (John Morrell) at 3,400. Citibank moved its main credit card center here from New York in 1981, and Wells Fargo and Citigroup remain large financial employers. All of that supports a lot of smaller businesses: service shops, warehouses, clinics, salons and dealerships. We put down commercial and shop floor epoxy for those spaces, with thicker coats where carts, lifts or forklifts run and texture where floors get wet.

The quartzite city

The pink rock you see around Falls Park is Sioux quartzite. The seven-story Queen Bee Mill there was built in 1881 from quartzite quarried on site, and only its foundation remains. That stone is part of why so many people here like a floor with color and texture. Flake blends in reds, tans and grays are a popular choice for garages, and metallic epoxy in warm tones is common in basements.

Humid summers count too

Winter gets the blame, but summer is when basement floors cause trouble. Wikipedia lists the city's average annual relative humidity at 69.1%, and about 15 days a year reach 90°F or higher. Warm, damp air drifting down to a cool basement slab can leave the concrete sweating and smelling musty. Before we coat a Sioux Falls basement, we test the slab in more than one spot. A moisture-tolerant primer handles a damp slab. Standing water or an active leak is a drainage problem, and we will tell you to fix it before we coat anything.

Matching the service to the space

• Attached two- and three-stall garages: garage floor coating with flake, our most common job in the city
• Garages you need back fast: polyaspartic floor coating, which can often take foot traffic the same day
• Unfinished or storage basements: basement floor epoxy in a solid color
• Finished basements, bars and media rooms: metallic epoxy floors
• Service bays, warehouses and clinics: commercial and shop floor epoxy with a thicker build

What to expect on your estimate

We come out, measure, test the slab for moisture and look at every crack, stain and old coating. You get a written quote with the system, each prep step and the price. For an attached two-stall garage on a newer street, most installs take one to two days. Older floors with heavy repair can take longer, and we will tell you that up front.
