Our customer reviews tell the story best. With a 4.8-star average across 186+ Google reviews and an outstanding 4.9-star rating on Angi (formerly Angie’s List), we’ve proven our commitment to excellence project after project.
Nationally, we’re proud to be the #1 Simonton Windows installer in the country. This highlights our volume, expertise, and customer satisfaction—giving our clients access to some of the best hurricane windows available today.
We’re also proud to hold an A+ rating from the Better Business Bureau, a distinction earned through consistent ethical business practices, verified accountability, and unwavering dedication to customer care.
As Tampa Bay locals, we understand the importance of protection, efficiency, and beauty in a Florida home. That’s why we specialize in hurricane-impact windows and doors—designed to withstand Florida’s extreme weather while improving energy efficiency, reducing noise, and enhancing curb appeal.
The Best Window Company for Florida Homes
At Karoly Windows & Doors, we offer beautiful high-performance hurricane windows and doors which meet or exceed Florida Building Code requirements for the greater Tampa Bay area.
We also offer a wide variety of styles and finishes to match the architectural personality of your home.
Some other benefits include:
- Select window models offer up to 50% noise reduction compared to standard glass.
- High performance in local conditions (in greater Tampa Bay, homes usually experience high UV exposure, high heat, high humidity, and can experience salt corrosion in areas close to saltwater).
- Excellent energy efficiency – we offer Energy STAR certified windows and doors
Our impact windows and doors also offer enhanced impact protection outside of hurricanes. In our own impact testing for hurricane windows and doors, our sliding glass doors withstood direct hits from a baseball bat, hatchet, and sledgehammer—while a competitor’s non-impact sliding door shattered in seconds.

Our Guarantees
At Karoly Windows & Doors, we stand behind our work with guarantees that provide real peace of mind. Here are our written guarantees.
Fixed Price Guarantee
Once we approve your order, that price is locked in—period. We cover any additional work required to complete your installation properly. If we encounter unforeseen issues during installation, that’s our responsibility, not yours. This guarantee eliminates the stress of budget surprises and allows you to plan with confidence.
On-Time Installations
We respect your time. When we schedule your installation, we commit to beginning and completing your project on the agreed-upon dates. Our professional teams arrive punctually, work efficiently, and leave your home clean. We understand that home improvement projects can disrupt your routine, and we work diligently to minimize that disruption.
Excellent Communication
We build trust through transparency.
- Your in-home consultation begins with meeting an installation expert, not a salesperson on commission.
- Our project management team (based in Clearwater and Tampa) maintains clear, open lines of communication throughout your project. You’re informed from start to finish.
Craftsmanship Guarantee
Our in-house installation teams are meticulously trained, detail-oriented, and polite. We guarantee that your windows and doors will be installed according to building codes and manufacturer specifications. This attention to detail ensures that your hurricane windows will perform as intended when you need them most.
Satisfaction Guarantee
We’re fully committed to delivering excellence in every project. If you’re not completely satisfied with any aspect of our work, we’ll make it right. Homeowners are not required to cover any expenses for repair or replacement of parts, service or labor.
The Karoly Difference
No Subcontractors
Karoly Windows & Doors employs and trains all of our installers ourselves. We’re driven to be the best window company in Florida. The most important part of this is consistently great installers who have been trained to a high standard. Our general advice to Florida window companies (and homeowners) is that you probably won’t get consistently excellent results from a subcontractor you met this morning. A team of installers that has experience working together, is trained to a high standard, and has an unusual attention to detail will consistently deliver great installations with a higher quality of installation and a better track record of on-time delivery.
Training Excellence
Our installation specialists undergo comprehensive training followed by ongoing education for the latest industry standards and techniques. This investment in our team ensures that every installer is thoroughly versed in manufacturer specifications, building codes, and our own rigorous quality standards.
Each team member is trained in hurricane window and door installation techniques specific to our products and Florida’s unique environmental challenges.
Consistent, Proven Processes
Our in-house teams follow standardized procedures that have been refined over our 25 years in business. This standardized approach means your installation will be executed with precision—whether you’re in Tampa, Clearwater, St. Pete, or anywhere else in the Tampa Bay area.
From the careful removal of existing windows to the final inspection, our systematic process ensures nothing is overlooked.
Professionalism You Can See
When our teams arrive, you’ll know exactly who’s working on your home. Karoly installers show up in branded vehicles, wear company uniforms, carry proper ID, and treat your property with care and respect—protecting interiors and cleaning thoroughly after installation
Superior Customer Experience
When you interact with our installation teams, you’re speaking directly with Karoly employees who are empowered to address your concerns on the spot.
Our installers arrive in Karoly-branded vehicles, wear company uniforms, and carry proper identification. All of our installers are background-checked. This professionalism extends to every aspect of their work, from protecting your home’s interior during installation to thorough cleanup after project completion.

Our installers are the best in Florida. We stand behind our work with industry-leading warranties:
- Workmanship: 25 year warranty (or a lifetime warranty for Simonton products).
- Materials: up to a 50 year warranty on select products.
