What Makes Lexington Garages Different

A Small City Growing Fast

Lexington packs roughly 916 households into less than a square mile, giving it a population density of about 3,261 people per square mile, noticeably higher than many surrounding Anoka County cities. About 33 percent of those households include children under 18, and married-couple households make up 38.1 percent of the total, meaning many local garages see daily use from families juggling multiple vehicles, sports gear, and seasonal storage. The city has also seen a striking jump in population in just two years, adding hundreds of new residents and putting more everyday wear on existing infrastructure, including garages. Our team sees this growth firsthand in the steady stream of both older homes needing restoration and newer properties needing their first professional coating.

Owner and Rental Properties Side by Side

One detail that stands out in Lexington's housing data is the gap between its homeowner vacancy rate of just 0.2 percent and its rental vacancy rate of 21.5 percent. That contrast points to a community built around long-term, stable homeownership alongside a meaningful rental housing market that turns over more frequently. Property managers overseeing rental units need flooring that survives tenant changeovers and inconsistent upkeep between residents, while longtime homeowners are often more focused on fixing decades of accumulated wear. We work with both groups regularly, and our recommendations shift depending on which situation a property falls into.

The Concrete Problems We See Most Often

Sandy Soil and Shifting Ground Conditions

Lexington sits entirely on the Anoka Sand Plain, near Anoka, which gives the whole city its flat, uniform landscape but also affects how moisture moves through the ground beneath every slab. Sandy subsoil drains differently than the heavier clay found elsewhere in the Twin Cities metro, and that difference can create fluctuating moisture conditions depending on the season and recent rainfall. This shifting ground is part of why we see hairline cracking and minor slab settling in Lexington garages even when there is no major structural problem underneath. Our moisture testing process accounts for this sandy substrate specifically, since guessing at ground conditions here leads to coatings that fail early.

Salt, Slush, and Highway Commutes

Lake Drive, also known as County Road 23, runs directly through Lexington, and the city sits close enough to Interstate 35W that a large share of residents drive salted highways every day during the winter. Vehicles carry that corrosive brine straight into attached garages on their tires and undercarriages, and unsealed concrete absorbs it almost immediately. As temperatures swing above and below freezing throughout the season, that trapped salt and moisture expands and contracts repeatedly, gradually pitting and scaling the surface of the slab. A properly sealed epoxy floor blocks this cycle entirely, keeping salt brine on the surface where it can simply be wiped or squeegeed away.

Decades of Wear on Older Slabs

Many homes in Lexington predate the recent growth spurt that pushed the population toward its current estimate of over 3,000 residents, and older garage slabs often show the effects of that age. Aggregate pop-outs, spiderweb cracking, and old petroleum staining are common in these garages, built up gradually over fifty or more years of continuous use. Simply painting over this kind of damage rarely works, since cracks and weak points tend to work their way back through even a heavy topcoat within a year or two. Our repair process addresses this damage directly rather than covering it up temporarily.

How We Fix It: Our Core Installation Process

Real Diamond Grinding, Not Chemical Shortcuts

Every lasting installation starts with mechanical preparation rather than acid etching, which introduces unwanted moisture and chlorides into a slab without creating a real bonding surface. Our team uses planetary diamond grinders paired with HEPA dust extraction in our surface preparation to strip away old sealers and open up the concrete to the proper surface profile. This step matters more in a city like Lexington, where a large share of the housing stock is older and has likely never had a professional coating applied before. Skipping this preparation is the single biggest reason retail epoxy kits fail within a season or two of application.

Structural Repair Before Any Coating Goes Down

Once the surface is properly ground, our team routes out any existing cracks and fills them with structural epoxy or polyurea repair compound rather than leaving them for the new coating to hide. This matters especially for mid-century homes along Lexington's established residential blocks, where decades of freeze-thaw cycling have caused real structural movement in the slab. After the repairs cure, we grind everything flush with the surrounding concrete so the finished floor sits level and uniform from wall to wall. Only once this groundwork is complete do we move on to the actual epoxy base coat.

Sealing It All In With the Right Topcoat

The final layer of any installation is what protects everything underneath it from daily wear, sunlight, and chemical exposure. We finish our systems with UV-stable polyaspartic or polyurethane topcoats that will not yellow or haze when exposed to sunlight through an open garage door. These topcoats also resist hot tire marks, brake fluid, and other automotive chemicals that are a normal part of everyday garage use. Together with our epoxy base, this layered approach is what allows a Lexington garage floor to look and perform well for many years rather than just a few seasons.
