Why Should You Replace Old Home Windows
Typically windows last 10 to 80 years. Call in a professional for window replacement once you start to notice the signs that your windows are at the end of their lifespan. Replacing windows will save you money on utilities while improving the security, comfort, and appearance of your home.
At Green T Services, we use Low-E glass and vinyl frames for every window. Low-E glass is proven to reduce the UV rays from the sun, protecting windows from radiation, making them energy efficient and ENERGY STAR® certified.
Vinyl frames are resistant to the expansion and contraction that comes with changing weather. The combination of these features leads to high-quality, eco-friendly windows that lower energy bills and last longer.
No matter the style of window you choose, our installation process is fast and straightforward.
Our certified window installers will come to your home and measure for new replacement windows and send the dimensions to our trusted manufacturers. Once the windows are ready, our technicians will return to install your replacement windows.
Types of Replacement Window Installation
Double-hung
Double-hung windows feature two sashes that tilt in and move up and down. These windows are great as a low maintenance, easy to operate choice.
Sliding
Sliding windows can be customized to fit the size and style requirements of your home. These windows are easy to clean and versatile, making them great for large spaces.
Casements
This secure and stylish option uses hinges to attach frames to the sides of the window. Casement windows feature a center bar and come in bay, twin, bow, and triple configurations with either blind panel inserts or glass blinds.
Picture
These windows are fixed in their frame and provide an excellent view of the outside. Picture windows are the perfect addition to large rooms.
Garden
Garden windows feature a top pane that resembles a roof, creating a box space that allows plants to bathe in sunlight. Garden windows are best for kitchens because they are angled 90 degrees from the wall.
Bay & Bow
Bay and bow windows have panels that project outwards from the home’s exterior. These windows let in natural sunlight and open up the room, making them a fantastic addition to rooms with large walls.
Awning and Hopper
Awning windows swing open from the top to create a barrier that keeps rain out and lets in sunlight. Hopper windows feature a hinge at the bottom with a sash to open inward and bring airflow into the home.
Basement
Despite the name, we can do basement window installation in both basements and attics. These windows are usually in awning, hopper, or slider styles that bring fresh air into the home. Also called escape windows, they are perfect for providing a safe escape in an emergency.
Egress
Egress windows are large enough to be used as an entry and exit point. These windows are ideal in an emergency and feature steps or a ladder for this purpose.
Custom
Searching for a unique look? We are happy to offer custom window designs to meet your needs. We will work with you to create the ideal window for your home.

How much does window replacement cost?
What is a replacement window?
Replacement Window means the entire window frame, glass, and surroundings are replaced. Replacement windows are produced to replace old, broken, and worn-out current windows. They are installed in the current window frame. The current window opening is then measured so the replacement window fits perfectly in the opening.
Green T Services provides home window replacement near you to boost the curb appeal and energy efficiency of your home.
