When Arizona heat peaks each summer, homeowners in Chandler know that old windows can make cooling costs skyrocket. At L.J. Neal & Sons, our team provides locally built, energy-efficient L&S windows and patio doors that keep the heat outside and comfort inside. We are the trusted name in heat-stopping windows, helping Arizona homeowners enjoy quieter, cooler, and more efficient homes.
Our Extreme Series triple-pane windows are engineered for the desert climate. They reduce solar heat gain, lower energy bills, and protect interiors from UV damage. Whether you live near Ocotillo, Downtown Chandler, or Germann Road, our locally made L&S windows deliver proven results across every neighborhood and ZIP code.

Chandler’s long summers and 110-degree afternoons put windows to the test. Standard dual-pane glass simply can’t handle it, allowing excess heat and UV rays into your home.
Our Extreme Series triple-pane windows are built for Arizona’s extreme heat. With three layers of insulated glass and low-E coatings, they block up to 98 percent of UV and infrared energy. You’ll feel the difference right away, cooler rooms, balanced temperatures, and energy bills that finally make sense.
Every window is manufactured locally in Arizona using materials designed for this climate. From Price Road Corridor to Sun Lakes, Chandler homeowners choose our windows for their durability, clarity, and comfort.
Patio doors often leak more heat than any other area in your home. That’s why our heat-stopping patio door systems, featuring the same triple-pane technology found in our L&S Windows, are designed to keep your home comfortable year-round.
Each installation is performed by certified professionals who measure, fit, and seal every frame precisely. The result is a cooler, more efficient living space that performs season after season.
From Ocotillo Golf Club to East Ray Road, Chandler homeowners trust our team to replace outdated doors with modern, energy-saving options that look as good as they perform.


We take pride in building our windows and patio doors locally, supporting Arizona workers and families. When you choose L.J. Neal & Sons, you’re choosing craftsmanship made for desert living.
Our products are tested in the same harsh climate they’re built to withstand. They resist sun damage, prevent fading, and keep homes cooler through the toughest months of the year.
