Sliding and French patio doors that flood your home with light, open onto the backyard, and seal tight against the Texas heat — installed by Allstate's own crews.

A new patio door changes how a room feels — more light, a wider view, and easy access to the patio or pool. We install both smooth-gliding sliding patio doors and classic French doors, including NT sliding patio door systems.
Just as important in Houston: a properly installed, weather-tight patio door keeps the heat and humidity out and your cooled air in.
Sliding doors save space and give a clean, modern look with big glass; French doors open wide and add a classic feel. It comes down to your space and style — we'll help you choose during the estimate.
Much more. Modern patio doors use Low-E insulated glass and tight weatherstripping, so they stop the drafts and heat gain that old sliders let through.
Yes — current patio doors come with sturdier frames and multi-point or reinforced locking that's far more secure than older sliders.
A patio door is one of the largest openings in your home, so a smooth-gliding, weather-tight install matters a great deal. Here is how we do it.
We measure the opening, check the frame and threshold, and help you decide between a sliding or French system based on how you use the space and how much room you have to swing a door.
You pick an NT patio door in the configuration, glass, and finish you want. We order it built to your exact opening so it glides and seals the way it should.
Our crews set the door level, seal it against air and water, and fine-tune the rollers or hinges until it operates effortlessly. Then we clean up and leave.
A good patio door does two jobs at once: it opens your living space to the backyard and it holds the line against Houston's heat, humidity, and storms. An old, sticking, drafty slider fails at both — it leaks conditioned air, it fogs up, and it can be a security weak point. The NT sliding and French systems we install fix all of that.
Sliding doors are the space-saver, gliding along a track without swinging into the room — ideal for patios and tighter layouts. French doors make more of a statement and throw the opening wide when you want the indoors and outdoors to become one space. Either way, energy-efficient glass and proper weatherstripping keep the summer heat where it belongs, and a precise installation by our own crews means no drafts, no water intrusion, and a door that still glides smoothly years from now. From The Woodlands to Pearland, it is one of the more satisfying upgrades a home can get.

It comes down to space and style. Sliding doors do not swing into the room, so they are great for tighter patios and layouts. French doors open wide for a bigger, more dramatic connection to the outdoors. We will help you weigh both against your space at the estimate.
Yes. A modern NT door with energy-efficient glass and proper weatherstripping stops the heat gain and air leaks an old slider lets through — which your AC will thank you for during a Houston summer.
That is exactly what a proper replacement solves. New rollers, a level installation, and a track that is not worn out mean the door glides with one finger. We adjust every door on-site until it operates smoothly before we call the job done.
