Replacement Windows and Doors

Replacement Doors

Straightline Siding can help you find the perfect replacement door that will provide beauty, energy efficiency and increased curb appeal. We use Therma-Tru entry door systems. Therma-Tru is the brand that most builders prefer, and they have the best warranties in the industry.

Patio Doors extend your connection with the great outdoors, visually expanding and brightening any room. You can choose from vinyl or aluminum, sliding or hinged and several different color options. Enjoy durability, fresh air, safety, energy efficiency and enhanced curb appeal with a new storm door.


Replacement Windows

Replacement vinyl and aluminum Windows from Straightline Siding deliver beauty as well as energy savings, reduced maintenance and a more comfortable home. These windows are custom made to fit your current window openings precisely making them much easier to install and requiring no additional wall construction.

The vinyl frame and sashes are fusion-welded making them structurally sound to stay in great shape for years to come. These sleek windows complement any decor and they're so efficient, they cut energy costs sharply.

Thermally broken Aluminum windows dramatically reduce heat and cold transfer through the aluminum, an exceptional insulator like wood and vinyl but with the durability of aluminum. Straightline Siding uses Don Young Aluminum Windows.

Our NT Windows are designated Most Efficient Windows by ENERGY STAR for the second year! Click here to learn more.
