Casa Grande homeowners experience some of Arizona’s highest summer temperatures, and standard windows simply cannot keep up. When the heat pours through old glass, comfort disappears and cooling costs climb fast. L.J. Neal & Sons provides heat-stopping window and patio door replacement designed to perform where other systems fail, including our high-quality L&S windows.
Our Extreme Series triple pane windows, including L&S windows, are made and tested in Arizona for real desert performance. With more than seventy years of experience and five years serving Arizona, we deliver locally built products that protect your home, improve comfort, and help you save on energy every month.
From neighborhoods near Pinal Avenue to homes off McCartney Road, families in Casa Grande rely on our craftsmanship and expertise for windows that truly make a difference, including our exceptional L&S windows.

Casa Grande’s combination of desert heat and bright sun pushes every part of your home’s insulation to the limit. Dual pane glass lets heat in and air conditioning out, making your system work harder and your home harder to cool.
Our Extreme Series triple pane windows feature three layers of insulated glass with specialized low emissivity coatings that block up to 98 percent of UV and infrared rays. This technology keeps your rooms cooler, protects interiors from fading, and lowers your monthly energy costs.
Every window is manufactured in Arizona, using materials built to handle high heat, dry air, and sudden temperature swings. From Mission Royale to Copper Vista, homeowners trust our windows for consistent comfort and dependable quality.
The benefits start immediately. Rooms stay more balanced, air conditioners cycle less, and the house feels quieter and more comfortable.
Large glass doors bring in light but also heat. Our triple pane patio doors from L&S Windows are engineered with the same technology as our windows to stop heat before it enters your living space.
Each door is measured, fitted, and sealed by certified installers to ensure a perfect finish. After installation, homeowners notice cooler rooms, smoother door operation, and improved energy efficiency.
