Residential Window Replacement
5,000+ Happy Clients
Who this is for
- Homeowners with single-pane or builder-grade windows that never sealed properly
- Anyone watching the summer cooling bill climb while rooms stay uneven, room to room
- Owners of foggy double-pane windows where the seal between the panes has failed
- Homeowners preparing to sell, who want the curb appeal back before it's listed
What's included
- A free in-home consultation — materials, energy performance, and value explained before price
- Precision measurement of every opening, so the window is built to your house and not the other way round
- Double-pane glass with a Low-E coating and argon fill
- Full-frame installation — the whole frame, not an insert dropped into the old one
- Sealing and finish detail at each opening
- Floors and furniture covered before the crew starts; clean-up when they're done
The short version
What actually makes a replacement window energy-efficient
| Component | What it does |
|---|---|
| Double-pane glass | Two panes with a sealed space between them, instead of a single sheet of glass conducting heat straight through the wall. |
| Low-E coating | A microscopically thin coating that reflects heat while letting light through — it keeps Texas summer heat out and winter warmth in. |
| Argon fill | A safe, invisible gas sealed between the panes. It insulates better than plain air, and you will never know it's there. |
| Full-frame installation | Replacing the whole frame rather than the sash alone, so the opening gets sealed correctly instead of hiding an old, leaking frame behind a new one. |
What the EPA says
“Replacing old windows with ENERGY STAR certified windows lowers household energy bills by an average of up to 13 percent nationwide when replacing single-pane windows.”
That's a national average from the EPA, not a promise about your house — what you actually save depends on what you're replacing and how well it was sealed to begin with. It's the honest starting point for a conversation, which is why we'd rather show you the numbers than quote you a headline. ENERGY STAR sets its bar with U-Factor and Solar Heat Gain Coefficient targets that vary by climate zone, so in Texas, rejecting summer heat matters as much as holding warmth in winter.

In their words
What DFW homeowners tell us
The window installation went very well! They arrived promptly and had a streamline process. They knew exactly what they were doing and wasted no time getting the job done. They covered my home and furniture to minimize the mess. The service men were professional and courteous. The minimal clean-up was completed after the installation. My windows are beautiful and immediately improved the value of my home. I highly recommend Sun Smart to homeowners interested in increasing the beauty of their home.
Brian and Clint showed up on time and quickly got to work. The windows were installed and look amazing. I am very satisfied with the service and the product.
Good questions
Questions we get asked about this
The things DFW homeowners want to know before they commit.
We replace the full frame, because that's the only way the opening itself gets sealed. An insert leaves the original frame in place; if that frame was never sealed correctly, or has taken on water, an insert hides the problem behind a new window instead of fixing it. At your consultation we'll show you what your openings are actually doing.
Usually — but the honest answer is that it depends on what you have now. ENERGY STAR puts the national average at up to 13% off household energy bills when replacing single-pane windows. If your current windows are newer double-pane units in good shape, expect less. We'd rather set that expectation up front than sell you a number.
Floors and furniture get covered before any work starts, and the crew cleans up when the job is finished. That's the standard, and it's what our customers describe in their reviews.
Most projects are installed in as little as 7 days from final measurement. Your consultation gives you a clear schedule for your specific home, rather than a vague window.
Then they get built to fit. Arched, oversized, and unusually proportioned openings are made to measure rather than forced into the nearest stock size — that's our custom windows service.
