French Door Installation

French doors add character to any space — from a master bedroom to a home office to a back patio. We install interior and exterior French doors with glass panels, handling everything from the initial measure to the final hardware adjustment.

Interior and exterior French door installs are different jobs with different considerations. An exterior French door has to be weather-sealed, properly flashed, and set square in the frame to prevent air and water infiltration — issues that show up fast in East Texas humidity. Interior French doors are more forgiving structurally, but the glass panel sizing and frame fit still have to be right or you’ll see gaps and swing problems. Common reasons homeowners replace French doors include fogged or cracked glass panels, warped frames from moisture, and outdated hardware that no longer latches cleanly. We can often replace just the glass panel rather than the full door unit, which saves money when the frame itself is still in good shape.

Our commercial door work includes:

  • Storefront glass door systems

  • Office and tenant-finish entry doors

  • Security bar door systems

  • Interior commercial glass doors

Commercial Glass Doors & Entry Systems

Storefronts, office suites, retail entries — commercial glass doors take more wear and have to look professional every day. We install commercial glass door systems for businesses across Longview, from straightforward single-door entries to full storefront glass systems.

Commercial door installs require a different approach than residential work. We coordinate around your business hours so you’re not losing a full day of operation, and we’re used to working on active job sites where other trades are moving around us. For security door systems — glass combined with steel bar frames — we handle the glass fabrication and installation and can coordinate with your ironwork contractor on fit and clearances. If you’re a property manager or general contractor with multiple tenant spaces, we’re happy to discuss volume scheduling so your project stays on track.

Why Homeowners & Businesses Choose Chasteen G&M

We Measure the Whole Opening

Most companies measure the rough opening and call it a day. We look at the full system — frame condition, threshold, swing clearance, structural support — before anything is ordered. That’s how you avoid gaps, binding, and callbacks.

Local Crew. No Subcontracting.

The same team that measures your door is the team that installs it. We don’t hand your job off to someone you’ve never met.

Clean Installs on Active Job Sites

Whether it’s a home remodel or a commercial buildout, we show up on time, work clean, and leave the site the way we found it.

Sliding Glass Patio Doors

A well-fitted sliding door changes how a space feels — more light, better flow, a cleaner connection between indoors and out. We install sliding glass patio doors for homeowners across Longview and Gregg County, with a focus on proper alignment, smooth operation, and a finish that lasts.

Before anything is ordered, we assess the full opening — not just the glass size. That means checking the frame condition, the track, the threshold transition, and the structural support on both sides. A sliding door that’s even slightly out of square will bind, leak air, or wear unevenly over time. Getting the measure right upfront is what prevents those problems. Once we have everything we need, we’ll give you a clear timeline for the order and coordinate the install around your schedule. Most residential sliding door installations are completed in a single visit.

What we assess before installation:

  • Frame and opening condition

  • Track alignment and structural support

  • Clearance and threshold transition

  • Glass type and energy performance needs
