Window styles
- Double-hung: both sashes slide up and down.
- Single-hung: only the bottom sash moves.
- Casement: opens outward with a crank.
- Sliding: opens side to side.
- Picture: does not open, but gives a large view.
Frame materials
- Vinyl: affordable and energy-efficient.
- Wood: classic look, needs upkeep.
- Fiberglass: strong and stable.
- Aluminum: slim and durable, but conducts heat more.
Glass features
- Double or triple panes.
- Low-E coatings to reduce heat gain.
- Gas fills between panes.
- Laminated or tempered glass for safety.
Insert vs. full-frame
An insert window fits into the existing frame. It costs less but reduces the glass area slightly. A full-frame replacement removes the old frame, which allows repairs to rot and better flashing.
What affects the price
- Number and size of windows.
- Frame material.
- Glass options.
- Insert or full-frame installation.
- Interior and exterior trim.
Questions to ask
- What are the U-factor and solar heat gain ratings?
- Insert or full-frame, and why?
- What does the warranty cover for glass seals and installation?
In Texas
Windows with a low solar heat gain rating help keep Texas homes cooler in summer. ENERGY STAR sets window ratings by climate zone, so look for windows certified for the southern zones.
Reading window labels
New windows often carry a National Fenestration Rating Council (NFRC) label with performance ratings:
- U-factor measures how well the window keeps heat from escaping. Lower is better, especially in cold climates.
- Solar Heat Gain Coefficient (SHGC) measures how much solar heat passes through. Lower values block more heat, which matters in hot, sunny climates.
- Visible transmittance shows how much daylight comes through.
- Air leakage shows how much air passes through the window assembly.
ENERGY STAR sets recommended ratings by climate zone. In hot climates, a low SHGC usually matters most, because blocking solar heat lowers air conditioning costs.
Installation quality
A high-quality window installed poorly can leak air and water. A good installation includes checking the opening for rot, using a sill pan or flashing to direct water out, shimming the window level and square, insulating the gap between the window and the frame with low-expansion foam or backer rod and sealant, and integrating the window with the house wrap or siding. Ask the installer to explain how they flash and seal the windows.
Replacing windows in stages
Replacing all windows at once is often cheaper per window and gives a consistent look. If the budget is limited, starting with the worst windows, those with rot, broken seals or drafts, or the windows on the sunniest side of the house, can make sense. Make sure the installer can match the style and color later.
Lead paint in older homes
Homes built before 1978 may have lead-based paint on window frames and trim. Removing old windows can disturb it. Contractors who work in these homes must be certified under the EPA's Renovation, Repair and Painting rule and follow lead-safe work practices.
How long installation takes
An experienced crew can often replace several windows in a day. Insert replacements are faster. Full-frame replacements, which remove the old frame down to the rough opening, take longer and may require exterior and interior trim work.
Questions for installers
Ask about the window brand and model, NFRC ratings, installation method, flashing details, trim work, disposal and warranty for both the product and the labor.
Window treatments and energy
Even efficient windows benefit from window treatments. Cellular shades, exterior shades and solar screens reduce heat gain in hot climates, while heavy curtains help in winter.
Condensation on new windows
Condensation on the inside of new windows in cold weather usually means indoor humidity is high, not that the window is failing. New windows seal more tightly, so moisture that used to escape now shows on the glass. Running bathroom and kitchen fans helps.
Screens
Ask whether new screens are included. Full screens and half screens differ in price.
