Marvin® Replacement Windows: Premium Quality Products From An Industry Leader

Johnson County Siding & Window Company Of Olathe, Kansas Offers Homeowners Quality Window Replacement & Installation In Kansas City

Marvin® Windows are a fantastic replacement window solution because they are the perfect combination of beauty, durability, and energy-efficiency.

It starts with the material used to construct these windows: Ultrex fiberglass. It is eight times stronger than vinyl and three times stronger than vinyl/wood composites. It is also very durable, because Integrity windows remain stable in extreme temperatures and expands at nearly the same rate as glass. That means these windows stay air tight over time, giving them a longer life expectancy than typical windows.

Marvin® Windows also have a superb finish that looks great and resists fading, chalking, cracking, and peeling. This line of windows can match any home, with several popular styles and design options.

These windows aren’t just beautiful and durable; they are also energy-efficient. All Marvin® products meet or exceed federal ENERGY STAR® guidelines, saving you money on energy bills.

Marvin® Windows pioneered the fiberglass window market over 15 years ago and offer three distinct series of fiberglass windows to suit your home window replacement needs. You’ve heard of vinyl, you’ve heard of aluminum, but what you haven’t heard is that Ultrex® Fiberglass outperforms them both! Johnson County Siding & Window Co., Inc. is proud to offer Marvin® Window Products to our customers. Our many years of sales and window installation in Kansas City have led to one conclusion: no two remodeling or replacement window projects are alike. That’s why Marvin® offers an abundance of window replacement options including sizing, equipment, aesthetic, performance and configuration capabilities!

Our Customers LOVE The Results

Johnson County Siding & Window Co.
"Johnson County Siding & Window installed all new windows and vinyl siding this summer. Justin was honest and provided great information without a high pressure sales pitch. The crew that worked on my house was reliable, hard working, and considerate. Very pleased with the service as well as with the end product. House looks amazing!”

- Rebecca T.
Johnson County Siding & Window Co.
"Updated the outside of our home by replacing our 1970/1980s brick with a more modern dry stack stone. A very professional and trustworthy company. We couldn’t be happier with the work that was done. They also inspected our James Hardy Siding while they were here, and after finding little to no repairs needed, referred us to another great company for exterior painting.”

- Allen K.
Johnson County Siding & Window Co.
"We LOVE our windows!! Justin was so informative and helpful through the whole process from helping us decide which windows were best for our house to follow up after they were installed. The installers were amazing! I thought in the middle of summer, my house would be so hot while the windows were being replaced. But they did such an effecient, awesome job I didn't really notice any change in the temperature in the house. But I did notice a big difference once they were installed in keeping the heat out. Wow!! Can't wait to get all of our windows replaced.”
