Pricing depends on the system you choose and your garage’s square footage. Grind & Seal starts around $4.50/sq ft, Solid Color and Flake Systems range from $5.50–$7.50/sq ft, and Metallic finishes run $14–$16/sq ft. Polishing is quoted individually based on slab condition and desired sheen. Use our instant estimate calculator above for a ballpark, or contact us for an exact quote.
Solid color epoxy gives a clean, single-tone finish. Flake systems add broadcast color chips for texture, grip, and better stain-hiding. Metallic epoxy uses swirled pigments for a 3D, marbled designer look. If you’re not sure which fits your space, we’re happy to walk you through it.
When properly installed on a prepped, moisture-tested slab, our coatings are built to resist cracking and peeling for the life of your warranty. Most failures in DIY or lower-quality jobs come from skipping surface prep — which is why we grind and test every slab before coating.
Just clear the space of vehicles, storage, and floor-mounted items before your scheduled install date. We handle everything else, including grinding, repairs, and moisture testing.
Sweep or dust mop regularly, and clean spills (especially oil or automotive fluids) as they happen. For deeper cleaning, a mild soap and water mop is usually all you need. No special sealers or waxes required.
Yes, our coatings are designed to handle the moisture, road salt, and temperature swings common in Portland-area winters. Proper moisture testing during installation is what keeps the floor performing long-term in our climate.
In most cases, yes. Minor cracks and surface damage are repaired as part of our prep process before coating. Severely damaged slabs may need additional repair work, which we’ll always discuss with you upfront.
We back our installations with a lifetime warranty against peeling and delamination when properly maintained.
Yes, we do. Contact us for specific financing options.
Both. If you’re building new, we can coordinate directly with your builder or contractor to schedule the coating once the slab has properly cured. For existing homes, we assess your current concrete during the consultation and prep accordingly.
“Hot tire pickup” (the slight marking that can happen when a warm tire sits on certain coatings) is mostly a concern with lower-quality DIY epoxy kits. Our professional-grade systems are formulated to resist this, so it’s not something you need to plan around with a properly installed floor.
There is an odor during application and curing, similar to most coating products. We recommend keeping people, pets, and the space itself well-ventilated and clear during the install window, and we’ll walk you through exact timing for when it’s safe to be back in the space.tent
It depends on what’s there. Old paint or peeling coatings typically need to be mechanically removed before we can install a new system. Tile usually needs to be removed as well, since our systems are designed to bond directly to prepared concrete. We’ll evaluate this during your on-site consultation.
Most residential flooring projects like this don’t require a permit, since we’re not altering structural elements. If your project is part of a larger renovation that does require permits, that’s typically handled by your general contractor.
Minor cracks are repaired as part of our standard process. If we uncover a larger structural issue or a persistent moisture problem during moisture testing, we’ll stop, explain what we found, and discuss options with you before moving forward, rather than coating over a problem that could cause failure later.
We offer 23+ standard flake color options, and we’re happy to discuss custom blends for larger or more design-focused projects. Custom blends may affect lead time, so it’s worth mentioning during your consultation if you have something specific in mind.
Coatings need a certain temperature and humidity range to cure properly, which is part of why we test conditions before every install. In the Portland area, this occasionally affects scheduling during unusually cold, wet, or humid stretches, we’ll flag this during your consultation if your install date could be impacted.
While we can’t guarantee a specific return, a clean, professionally finished floor is one of the more noticeable upgrades buyers see in a garage or basement, and it signals the space has been well cared for.
Yes, surface prep includes addressing existing stains as part of the grinding process. Deep-set or long-term stains are generally resolved through this mechanical prep rather than chemical cleaning alone.
Yes, we regularly work around floor drains in garages, basements, and commercial spaces. We’ll coat up to and around the drain, maintaining proper function.
We don’t have a strict minimum, but very small projects may be subject to a minimum service charge to account for setup, materials, and crew time regardless of size. We’ll confirm this upfront if it applies to your space.
Yes, we typically require a deposit to schedule your project, with the remaining balance due upon completion. Exact terms are outlined in your quote, and financing is available if you’d prefer to spread out payment.
Yes. We’re happy to provide documentation upon request, this is worth confirming with any contractor before work begins on your home.
Often, yes. Bring a photo or let us know what you saw. In many cases we can identify the system and flake blend and recommend the closest match, or something similar that fits your goals.
Yes, we regularly coordinate with contractors and builders on new construction, renovations, and multi-unit or commercial projects. If you’re a builder looking for a flooring partner, reach out and we can discuss scheduling and volume pricing.
