The Situation Driving This Search
Your electric bill spikes every June and stays high through September. You’ve had the HVAC serviced, added insulation, and changed the filters. The windows are what’s left — and they’re probably the biggest remaining source of heat gain in your home.
Why It Matters in Austin
Every summer month with original single-pane windows costs more in cooling than the same month would with Low-E glass. The difference compounds over years. Austin averages 232 sunny days per year — that’s 232 days of solar heat gain through uncoated glass.

Common Questions Before You Call
How much will new windows cost?
Window replacement costs in Austin typically run $300–$800 per window installed, depending on size, frame material, and glass type. Whole-house replacement projects range from $4,000 to $20,000+ depending on window count and specifications. We provide written pricing before work begins — no surprises.
Can’t I just have my current windows repaired instead?
If your windows have a single cracked pane or a broken latch, repair may make sense — we recommend contacting your original installer or a glass specialist for repair work. If your windows are fogging between panes, frames are warping, or you’re seeing a pattern of seal failures, replacement is typically more cost-effective than repeated repairs.
How long does window replacement take?
Single window: 1–2 hours. Whole house (10–15 windows): 1–2 days. We install one window at a time so your home is never fully open to the outside at once.

Frequently Asked Questions
What does Low-E coating do for Austin homes?
Low-E (low-emissivity) coating is a microscopically thin metal layer applied to the glass surface. It reflects infrared heat — blocking 40–70% of solar heat gain depending on specification. For Austin’s west-facing windows, Low-E coating is the single most impactful glass upgrade available.
What ENERGY STAR specs apply to Austin?
Austin falls in the South-Central climate zone (IECC climate zone 2B). ENERGY STAR certified windows for this zone require a U-factor of ≤0.30 and a Solar Heat Gain Coefficient (SHGC) of ≤0.25. These specs prioritize solar heat rejection — the primary concern in Austin’s climate.
Do you repair energy-efficient windows?
We specialize in full window replacement and new window installation. For repair of existing windows, we recommend contacting your original installer or a local glass repair specialist.
How much can I save on cooling costs with new windows?
Savings vary widely depending on home size, HVAC efficiency, and baseline window performance. Many Austin homeowners report 15–25% reductions in summer cooling costs after replacing original builder windows with Low-E double-pane units. We don’t promise specific dollar amounts — the actual savings depend on your specific home.
