Energy-Efficient Windows
Cut energy loss and quiet your home.
Materials
What we install vs. what corner-cutters use.
Frame
Fiberglass or clad-wood frames — dimensionally stable in Texas heat, best long-term.
Cheapest builder vinyl that warps, seals fail, and won't hold paint.
Why it matters: Frame material decides whether your windows still open smoothly in year 20.
Glass package
Dual- or triple-pane low-E glass with argon fill, tempered where code requires.
Single-pane or basic dual-pane with no low-E coating.
Why it matters: Low-E and argon cut solar heat gain in half. Your AC bill notices.
Install method
Full-frame replacement with new flashing, peel-and-stick membrane, and low-expansion foam.
Insert windows shoved into rotted frames with a bead of caulk.
Why it matters: Insert-only installs skip the water-management layer. The window works — until the wall behind it rots.
Warranty
Lifetime frame and glass warranty from Anlin, Milgard, or Andersen, plus our labor warranty.
1-year window warranty and no labor warranty — if it fails, you pay to reinstall.
Why it matters: A real warranty covers both the product and the labor to swap it out.

A predictable path — with real durations.

FAQs
Answers before you ask.
Retrofit or full-frame?+
Retrofit is faster when the existing frame is sound. Full-frame is required when the frame is rotted or you're changing size.
Will I really save on energy?+
Replacing single-pane with modern low-E dual-pane typically drops HVAC load 15–25% in older homes.
Do you handle stucco patching?+
Yes—when full-frame replacement is needed, stucco cut-and-patch is included.
What warranty do I get?+
Lifetime limited from the manufacturer on the unit, plus our labor warranty on installation.
