Ways to save in Katy
- Do the whole house at once — per-window labor drops sharply after the first few openings.
- Choose insert installs when the existing frames are sound; that alone saves 25–35%.
- Claim the 25C federal tax credit: 30% of cost, up to $600 per year for qualifying ENERGY STAR windows.
- Standard sizes and stock colors cost far less than custom shapes or dark exterior finishes.
- Buy in winter — window companies discount hardest in their slow season.
