Cities we serve in Collin County
Collin County counted 1,064,465 residents at the 2020 census, and 2025 estimates already put it at 1,297,179 — McKinney is the county seat, Plano its largest city, and the corridor between them is filling in fast.
SunSmart Windows serves the whole county from our Dallas and Rockwall offices. Wylie sits on the Rockwall County line, so southeastern Collin County is often closest to SunSmart of Rockwall; everywhere else, SunSmart of Dallas is usually the shorter drive.

What we install
Five ways to let the right light in
Whichever one you need, it starts the same way: a free in-home consultation, where we explain materials, energy performance, and value — before anyone talks price.
Also part of the job
- Double-pane glass
- Low-E glass + argon fill
- Full-frame installation
Why the glass matters
A cooler, calmer room — not just a new window
A Low-E coating is a microscopically thin layer that reflects heat while letting daylight pour through. It keeps the Texas summer sun out and winter warmth in, so afternoon light stops feeling like a heat lamp.
Between the panes, an invisible argon fill insulates better than plain air, and double-pane glass quiets the street. Together they trade glare and drafts for steady, comfortable daylight.
Slide the dial to feel the difference between harsh single-pane glare and filtered Low-E comfort — same home, same afternoon.

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
Collin County, answered
The practical details of a SunSmart project in Collin County.
Yes — all three, along with Allen, Wylie, Prosper, Celina and the smaller Collin County towns between them. If your city isn't in the list above, call us; the list names the places we're asked about most, not the edge of the service area.
The one nearest you. SunSmart of Dallas covers most of the county, and SunSmart of Rockwall is often closer for Wylie, Murphy and the southeastern corner. Every office installs county-wide — pick whichever you like in the quote form and we'll confirm your crew when we book your consultation.
No — and you don't need one. The consultation happens at your home, where the windows are: we measure, explain your material and glass options in plain language, and leave you a written quote. It's free, and there's no obligation.
Most projects are installed in as little as 7 days from final measurement, and the on-site work is typically 1–2 days. Your consultation will give you a clear timeline for your specific home.
