Tennessee Window and Door Works is an authorized Home Guard dealer. We buy straight from the plant that builds the window. Home Guard Industries is a family owned manufacturer in Grabill, Indiana, and they have been building doors and windows for over 40 years.
Amish Craftsmanship
Home Guard builds in Grabill, Indiana, a town of about 900 people known for its custom cabinet shops. The people building your window come from a tradition of precision hand work. No shortcuts, no compromises.
We Know This Window Inside and Out
We have been to the plant in Indiana. We walked the line, watched these windows get built, and trained on the product with the people who make it. Ask us a question and you get a real answer, not a brochure answer.
Low Overhead, Not Low Quality
The big national brands run TV commercials, mailers, and billboards. All of that gets paid for out of your quote. We are a local Knoxville company with low overhead. Same tier of quality, less padding in the price.
A Warranty You Can Actually Read
Home Guard backs these windows with a lifetime limited warranty for as long as you own and live in your home. That covers the vinyl, the moving parts, the sealed glass unit, and even accidental glass breakage.
- Family owned, over 40 years
- Amish craftsmanship
- Cardinal Glass insulated units
- FlexScreen on every window
- Earthwise Group member since 2011
- Lifetime limited warranty
