New windows that cut bills and quiet your home
Old windows are easy to ignore until the power bill climbs and the house never feels right. Drafts, fog between the glass, and windows that stick are all signs the seals have given out.
TN Window Works replaces windows for homes across Knoxville and East Tennessee. We help you pick the right style and glass, then install them clean and tight so they last.
- Energy-rated glass that lowers heating and cooling costs
- Quieter rooms with less outside noise
- Easy-to-open, easy-to-clean windows
- Clean, on-time install with no mess left behind
Window styles we install
We carry styles to fit any home and budget. Here are the most common picks.
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.

Window replacement questions
How much does window replacement cost?
It depends on how many windows you replace, the style, and the glass. We give you a clear written quote up front with no surprises.
How long does it take?
Most homes are done in one to two days. We set a timeline before we start and stick to it.
Will new windows really lower my bill?
Yes. Old, leaky windows make your HVAC work harder. Energy-rated windows seal tight and ease that load, which shows up on your bill.
Do you offer a warranty?
Yes. Our products come with manufacturer warranties, and we stand behind our installation.
Do you offer free estimates?
Always. We come to your home, look at your windows, and give you a written quote at no cost.
