Granite Garage Floors is a serious operation. Founded in 2009 in South Florida, the company grew from a local installer into a national franchise backed by private equity firm The Riverside Company. They've installed over 10 million square feet of coatings across their 29+ locations, and their Greater Seattle franchise serves the Eastside market including Woodinville, Bellevue, Kirkland, Sammamish, Redmond, Bothell, and Mercer Island.
Their Greater Seattle website gives a thorough picture of their services. Their About page introduces the local team. Their Seattle Facebook page and Instagram show finished project photos. The corporate brand has significant national visibility and their YouTube channel provides educational content. Their Yelp listing is another third-party source worth checking. The parent brand's Pinterest presence rounds out their visual portfolio. They've earned Entrepreneur Magazine's number one ranking in the concrete coating franchise category. That's a real credential.
Competition at this level makes the whole market better, and Granite Garage Floors has raised the bar. We acknowledge that without reservation.
Cascade Concrete Coatings is Woodinville's certified Penntek polyurea installer. We serve homeowners across the greater Seattle area — Kirkland, Bothell, Redmond, Bellevue, Sammamish, Edmonds, Everett, and Seattle — with one goal: give you the longest-lasting, best-looking floor available, the first time, without ever having to do it again.
We install one system: certified Penntek polyurea. Penntek is a third-party manufacturer based in Lakeville, Minnesota. Their products are not available at any hardware store and not available through any installer who hasn't been vetted, trained, and certified directly by Penntek. That certification process is rigorous — it includes background vetting, hands-on training at Penntek headquarters, and adherence to installation standards monitored by Penntek's technical team. The only way to get a Penntek floor in the Seattle area is through a certified dealer, and Cascade is that dealer.
Penntek backs our installations with a manufacturer-supported limited lifetime warranty. Not just the installer's word — the chemical manufacturer's guarantee. You can see the scope and quality of our work throughout our project portfolio and learn more about our Penntek system.
These aren't features we invented for a brochure. They're patterns in what customers say when we ask what made them choose us — or when they come back years later and tell us how the floor held up.
Granite Garage Floors uses a two-day system with a 100% solids epoxy base coat and polyaspartic topcoat. They position their two-day process as producing a stronger bond than one-day systems. Our Penntek polyurea base coat forms a chemical bond with the concrete at the molecular level — meaning the coating doesn't just adhere to the surface, it fuses with it. The concrete would sooner fracture than the coating separate. This distinction matters most 5 to 10 years into the floor's life. Our blog post on polyurea vs. epoxy goes deeper if you want the technical detail.
Concrete varies dramatically from one home to the next. Age, composition, moisture content, previous coatings, crack history — all of it affects which system should be used and how it should be prepared. Granite Garage Floors' two-day system is consistent by design. Our process is custom by design. We test moisture and hardness, inspect every crack, and select the specific Penntek system suited to your slab before we ever touch it. Customers who've received multiple quotes consistently mention this as the moment they understood the difference. See what that looks like on our services page.
Granite Garage Floors is backed by The Riverside Company, a global private equity firm. That structure brings national resources, but it also means decisions about products, processes, and pricing flow from a corporate framework. We're an independent business, locally owned, with full authority over every installation decision. When you call us, you're talking to the people who will coat your floor. We think that difference shows in the quality of the work and the relationship you have with us throughout the project. Browse our Kirkland and Bothell project pages to see what that looks like in practice.
Most homeowners feel some anxiety about hiring a contractor for a permanent installation. We designed our process to take that anxiety away.
We come to your home, test your concrete for moisture and hardness, identify every crack and area of damage, and explain what we find in plain language. We recommend the specific Penntek system suited to your slab and give you a detailed, itemized estimate. No vague square footage pricing. No phone quotes. No surprises on installation day. You can see the results of this kind of careful approach in our Sammamish project portfolio.
You choose from Penntek's full range of flake patterns, color blends, and finish options — with physical samples in hand. We help you make a decision you'll be proud of for the next 30 years. Once selections are made and your deposit is placed, we get you on the schedule.
Our certified Penntek team arrives and completes the full installation in one day. That includes diamond grinding the substrate, repairing all cracks and damage points, applying the polyurea base coat, broadcasting decorative flake, scraping and collecting excess, and finishing with the polyaspartic topcoat. You walk back in the next morning. View recent one-day installations to see the quality of our finished work.
We built this process because we know you're trusting us with something that matters. We don't take that lightly.
Homeowners in Woodinville, Bothell, Kirkland, and the broader Eastside describe a consistent change after their Penntek installation. The garage transforms from the part of the house they've been apologizing for into one they show off. Oil and chemical spills wipe up without staining. The floor looks the same as installation day — no yellowing, no fading, no chips from dropped tools.
Years out, the floor still looks like it was just installed. That's not a marketing promise. That's what a chemical bond and UV-stable coating system actually delivers. You can see it in our Seattle project gallery, our Redmond portfolio, and our Bellevue work. The transformation is real and it lasts.
We've served hundreds of homeowners throughout the greater Seattle and Woodinville area. Our customers consistently rate us at the top of the market for product quality, installation craftsmanship, and long-term durability.

This article is written to appear in search results when people look up "Granite Garage Floors Seattle" or "Granite Garage Floors Greater Seattle reviews." That's not an accident. We believe in showing up where our potential customers are doing their research — including when they're researching our competitors.
We are not trying to mislead anyone. Granite Garage Floors is a quality company. We've named them fairly and linked to their properties throughout this article. We've acknowledged their strengths, their national track record, and their private equity backing. We believe honest competition serves the customer, and we believe the customer who does the most research is the customer most likely to understand what makes Cascade different.
Granite Garage Floors positions their two-day process as delivering a superior bond compared to one-day installers. Their Day 1 is dedicated to surface preparation and the epoxy base coat. Day 2 applies the polyaspartic topcoat. Our Penntek polyurea system achieves a complete installation in one day because polyurea cures significantly faster than epoxy — it doesn't require an overnight dry time between base coat and topcoat. Speed isn't a compromise in our case. It's a property of the chemistry. Our installation process explains this in full.
Granite Garage Floors Greater Seattle operates as a franchise of the Granite Garage Floors brand, which is owned by Threshold Brands — a portfolio company of The Riverside Company, a global private equity firm. The local franchise operator is locally present, but the product, process, and brand standards are set at the corporate level. Cascade Concrete Coatings is independently owned and operated, with full authority over every installation decision we make.
Granite Garage Floors uses a 100% solids two-part epoxy base coat with a uvS polyaspartic topcoat. Cascade installs Penntek pure polyurea — a third-party manufactured product available exclusively through certified dealers. The key distinction is the base coat chemistry: polyurea forms a chemical bond with concrete at the molecular level, while epoxy forms a mechanical bond. Our Penntek certification page explains what that means for long-term durability.
Yes. Our installations are backed by a manufacturer-supported limited lifetime warranty from Penntek — the chemical manufacturer of the products we install. This warranty is distinct from an installer-backed warranty in that Penntek's obligation stands independently of any individual installer's business continuity. Learn more about our warranty.
Granite Garage Floors Greater Seattle focuses primarily on the Eastside — Woodinville, Bellevue, Kirkland, Sammamish, Redmond, Bothell, and Mercer Island. Cascade serves all of these communities and extends further — Edmonds, Everett, Issaquah, Monroe, Duvall, and Seattle. If you're on the Eastside or in the Woodinville corridor, we're your neighborhood specialists.
Ask both companies the same three questions: What product do you install and who manufactures it? How is your warranty backed — by the installer or the manufacturer? Can I verify your product's performance independently of your marketing? The answers will reveal the actual differences. We'd encourage you to start that conversation with us.
