What Plano Homeowners Are Saying

A Higher Standard of Installation
★★★★★
Patrick B. – McKinney, TX
After comparing multiple vendors, they offered the most competitive pricing while still delivering high-quality windows and installation. What really stood out was the quality of the workmanship. Every window was installed to a very high standard, especially compared to a previous vendor I worked with where I experienced multiple issues. Matt being on-site throughout the project demonstrated a high level of integrity, ownership, and attention to detail.
Transparent From the First Email
★★★★★
Katie H. – Plano, TX
We compared 6 other companies and chose to go with Optimal. We really liked how he priced out each window on the invoice so we could upgrade different ones. He also sent all of his certifications on the first email so we didn’t have to look for them. He was not a sleazy salesman, and the windows are a great price. Matt was super transparent and made us feel confident in our choice.
Professional, Fast and Incredibly Clean
★★★★★
Rong-ti M. – Plano, TX
We had Optimal Windows replace all of the west-facing windows in our home with energy-efficient windows. The crew was professional, fast, and incredibly clean. They carefully removed and reinstalled our blinds. Honest, trustworthy, and highly skilled people. It’s rare to find a company that cares this much about doing things right.
43 Windows, Gold Star Service
★★★★★
Erik K. – Plano, TX
Matt and his company replaced 43 windows in our home at a very fair price. While his pricing was budget friendly, the level of service was gold star. Matt was here every day supervising and working alongside his crew, from setting in windows to cleaning up tiny bits of debris in the yard to polishing the new windows to perfection. We had very high expectations and they were exceeded.
Five Quotes, One Clear Choice
★★★★★
Amanda R. – Frisco, TX
After getting five quotes, we chose Optimal Windows and couldn’t be happier. Matt was never pushy and kept us updated throughout the process. The results look amazing, and within one month we already noticed lower electric bills. Photos show before/after with our new Burris windows—highly recommend!

Upgrade Spotlight

From Builder-Grade to
High-Performance Vinyl Windows

These Plano homeowners relied on exterior sun shades to control heat from their builder-grade windows. After upgrading to  high-performance Burris vinyl windows with Cardinal Low-E glass, the shades came off and the home stayed cooler and more comfortable naturally.

Why This Upgrade Worked

1 · The Problem
Sun Shades Covering Every Window

Exterior sun shades are often a sign the windows underneath are not performing. This home had them on nearly every opening just to keep rooms livable during Texas summers.

2 · The Change
High-Performance Burris Windows

We replaced the original builder-grade units with Burris Windows paired with Cardinal Low-E glass. The upgraded frame and glass package reduced heat transfer, improved insulation, and made the home more comfortable without relying on exterior shades.

3 · The Result
Enjoying the View Again, Without the Heat

With the shades removed, the home opened back up to natural light and clear backyard views. Inside, the rooms stayed cooler and more comfortable throughout the day with more natural light and less heat buildup.

Why Homeowners Trust
Optimal Windows

Accurate Measurements
and Planning

Every opening is measured and planned before anything is ordered, so your custom windows fit right and your installation day runs smoothly.

Not Sales Pitches

A good consultation should leave you more informed than when it started. We walk you through frames, glass and installation details that matter for your home, then give you an itemized proposal and the time to decide.
