What We Replace & Install.

Sliding Patio Door Replacement

The most common patio door replacement we handle. Old sliding doors that are warped, off-track, or inefficient get removed entirely and replaced with new, smooth-operating systems.

French Patio Doors

Hinged double doors that swing open for a wide, elegant entry to your patio, deck, or garden. We install new French doors and replace existing ones that have cracked glass, rotted frames, or failed seals.

Patio Door Glass Replacement

When the door frame and hardware are still solid but the glass is cracked, fogged, or outdated, we replace the glass panels without replacing the entire system. Patio door glass replacement saves money while restoring clarity, insulation, and appearance.

Multi-Panel & Bi-Fold Patio Doors

For larger openings, we install multi-panel sliding systems and bi-fold patio doors that stack or fold to create a seamless indoor-outdoor transition.

How Patio Door Replacement Works.

Step 1: Assessment We measure the opening, inspect the frame and threshold, and discuss your preferences. Sliding, French, bi-fold. Clear, tinted, or low-E glass.
Step 2: Material Selection Insulated glass, tempered glass, aluminum or vinyl frame, hardware finish. We recommend what fits your home's style, energy needs, and budget.
Step 3: Removal & Installation Old door comes out. New door goes in. Frame is leveled, anchored, and sealed. Glass is set, hardware installed, and weatherstripping applied. One crew handles the full job.
Step 4: Test & Cleanup Door gets opened, closed, locked, and checked for smooth operation. Track alignment, seal integrity, and drainage verified. Clean site. No debris.

Patio Door Replacement FAQ

What types of patio doors do you replace?

Sliding glass doors, French doors, hinged patio doors, bi-fold doors, and multi-panel sliding systems. We replace all types and configurations.

Can you replace just the glass in my patio door?

Yes. Patio door glass replacement is available when the frame and hardware are still in good condition. We replace the glass panel and reseal it without replacing the entire system.

How long does a patio door replacement take?

Most single-door replacements are completed in one day. Multi-panel or custom systems may take two days depending on the scope.

Do you install energy-efficient patio doors?

Yes. Insulated glass units with low-E coatings and argon gas fill are standard on our patio door replacements. Designed for DC-area climate performance.

What's the difference between sliding patio door replacement and repair?

Repair addresses specific components (rollers, tracks, glass, locks) while the existing door stays in place. Sliding patio door replacement removes the entire system and installs a new one. We recommend replacement when the frame is warped, the track is damaged beyond realignment, or the door is past its useful life.

Do you remove and dispose of the old door?

Yes. We remove the old patio door, frame, and hardware, and dispose of all materials. Your opening is left clean and ready for the new installation.

Are you licensed?

Fully licensed and insured across Washington, DC, Virginia, and Maryland.
