New windows, fit right and sealed tight
New construction, an addition, or a remodel all need windows that fit the opening and seal against the weather. A bad install lets in air and water no matter how good the window is.
TN Window Works installs windows for homes across Knoxville and East Tennessee. We set each window level, square, and sealed so it works smooth and keeps the weather out.
- Windows fit to the exact opening
- Tight seals that block air and water
- Smooth operation that lasts for years
- Clean job site when we finish
Windows we install
We install the full range of window styles for new builds, additions, and remodels.
Double-hung
Both sashes open and tilt in for easy cleaning. The most popular pick for most homes.
Casement
Crank-out windows that seal tight and let in a lot of air. Great for spots over a sink or counter.
Sliding
Glide open side to side. Simple, low-maintenance, and good for wide openings.
Bay & bow
Add space and light and give a room a view. A nice upgrade for living rooms and kitchens.
Picture
Big, fixed glass that frames a view and fills a room with light.
Energy-efficient glass
Double-pane, Low-E glass with insulating gas to block heat in summer and hold it in winter.
