Vinyl Replacement Windows

There are many styles of hurricane impact windows available for your window replacement project. The style we like best and which has the best warranty replacement process are double hung windows. These impact windows have an operable top and bottom sash and a tilt feature for easy cleaning and maintenance. While double hung replacement windows by Simonton are the best option, we also can order slider windows, casement windows, awning windows, picture windows, and geometric windows.

We only install retrofit windows with vinyl frames. Storm windows hold up the best against Florida’s year long summer sun and its season of hurricanes. The energy efficiency of vinyl windows makes them a much better choice versus aluminum for your replacement windows.

Cost of New Windows

Impact windows cost, on average, less when purchasing them for self-installation. Big Box stores offer these types of self-installation windows and may carry windows in inventory. The one problem is that these are nominal sized windows that are not custom replacement windows built specifically for your home’s exact openings and may not be up to the building code, pass an inspection, qualify for insuring your home, or perform to modern energy code minimum requirements. These types of windows exist to allow you to replace 1 to 2 windows as a temporary patch until a permanent, retrofitted window is installed by a licensed professional. There are two main aspects to consider for your new windows, the quality and guarantee of the windows themselves and the quality and guarantee of the installation behind them. Saving you money is absolutely one of our goals and that is why we make sure you get the correct windows for your project at the best price and that the installation is performed the right way. The cost of Karoly Windows & Doors installing your replacement windows is much less expensive than installing the wrong windows, incorrectly.

Exterior Doors by Karoly Windows & Doors

French doors, front doors, exterior doors, entry doors, whatever your preference in name one thing always remains the same, Karoly Windows & Doors offers the best exterior doors in the Bay area. We carry the top brands including Masonite by Florida Made Doors, BHI Plastpro, Provia, Advisar, and Thermatru. If you are in need of a new front door, call the best of the best in windows and doors!

Fiberglass Entry Doors

While these manufacturers do offer wooden doors and steel doors, we only install fiberglass doors. In coastal areas of Florida, fiberglass is the best material. Fiberglass holds up to inclement weather, salty and humid ocean air, and is much more energy efficient. Fiberglass doors can also come in a textured finish which gives the entry door a traditional wood door look without eventually rotting or swelling with moisture. These modern exterior doors are required to be painted or stained after installation if they are not pre-finished to seal the door and ensure the warranty.

Front Door Options

We have so many exterior doors to choose from. There are many options of decorative glass, privacy glass, and textures. Your replacement front door can be designed to fit your style. We have doors for every style whether they are rustic doors, contemporary doors, or modern exterior doors.

Pre-finished Residential Exterior Doors

A major trend in residential exterior doors is bold color options. All BHI Plastpro doors are required to be finished after installation. We have instructions for staining your front door or painting exterior doors. You can also get a pre-hung door already finished and have the best-looking doors in the neighborhood. Painting your door yourself? Be sure to get the correct paint for primed fiberglass, ask your local paint store for the best brand for your project.

DIY Exterior Door Replacement

Utilizing the best replacement door company in Clearwater comes with many benefits. While Big Box stores may carry quick replacement stock doors, there is usually extra construction, custom frame sizes, and custom sills required for proper installation. You can hire a sub-contractor from these stores, but you don’t know their background, level of skill, or have any guarantees on your installation. With Karoly Windows & Doors, the hardest part of the project will be choosing the door you like. We do the rest! With award-winning installation, perfected craftsmanship, rigorous quality control measures, and a 25-year workmanship warranty, our service is unmatched in Pinellas County and the Tampa Bay area.

I love my new windows and doors. It makes the house feel warmer, while the outside temp is in the 30's. Plus, the outside noise has reduced, greatly. Karoly and team did a great job from the initial estimate visit, to the office communications, and then the installation team. All professional and knowledgeable. Everything went smoothly and very impressive to watch.
