Trusted Patio Door Installation Nationwide

Patio door installation across the United States typically runs $1,500 to $4,500 for a standard sliding unit and $2,500 to $7,500 for hinged French patio doors, installed and trimmed. Most jobs finish in one day. At Westlight Windows & Doors, we’ve been installing doors since 2009 as an independently owned and operated Kingswell location, and Owen Satterfield built the business around a simple idea: you get a written price before any work starts and a guarantee that means something afterward. Call (903) 354-7134 and a live person answers, any hour, any day. If you’re also weighing other entry doors, see our door replacement page.

Patio Door Repair

Patio Door Repair means fixing the parts of an existing patio door that have worn out or broken, without pulling the whole unit. It is the right call when the frame is square and the glass is sound but the rollers, lock, handle, or weatherstripping have failed. Most repairs run $120 to $450 depending on the part and how hard it is to reach. Westlight Windows & Doors sends background-checked, uniformed technicians who arrive in the window we gave you, and the Kingswell Guarantee applies: written price, clean job site, written guarantee on the work.

Locks, Handles, and Latches

A patio door that won’t lock is a security problem, not a nuisance. We replace worn mortise locks, hook latches, and handle sets, usually for $120 to $300 installed. If the strike plate has pulled loose from a swollen jamb, we fix the jamb first so the new lock actually holds.

Weatherstripping and Seals

Daylight along the edge of a closed door means the weatherstripping has compressed or torn. New sweeps and bulb seals cost far less than the heating and cooling you lose through the gap, and the job takes under an hour in most homes.

Sliding Door Repair

Sliding Door Repair covers the track, roller, and panel problems that make a slider hard to open. The usual causes are flattened rollers, a bent or pitted track, and a panel that has dropped out of alignment over the years. Replacing a pair of rollers typically runs $150 to $350, and a track repair or replacement runs $200 to $500. We tell you plainly when a repair will last and when you are throwing good money at a door that has reached the end of its life.

Rollers and Tracks

Most stuck sliders aren’t dirty, they’re worn. Steel rollers flatten and the panel starts to drag on the track, which grinds the aluminum and makes the next repair more expensive. Fixing it early keeps the repair small. Heavy glass panels need two people and the right lifting gear, which is another reason to skip the do-it-yourself attempt.

Panel Alignment

A panel that has settled leaves a gap at one corner and rubs at the other. We adjust the roller height, square the panel, and check the lock engagement before we leave. If the frame itself has racked, we will say so and give you the replacement price in writing right then.

Patio Door Replacement

Patio Door Replacement means taking out the old door, frame, and threshold and setting a new unit in the same rough opening. You need it when the frame has rotted, the glass has fogged between the panes, the door no longer seals, or repairs have started to cost more than the door is worth. Typical replacements run $1,800 to $5,500 installed, based on size, glass package, and material. Westlight Windows & Doors has handled these swaps since 2009, and we compare your options in writing so the price and the product are both clear before work starts.

Reading the Rough Opening

The old door tells us what’s behind it. Soft wood at the bottom of the jamb usually means water has been getting in, and we open that up before the new door goes in. Setting a new unit over hidden rot is how a two-year-old door ends up leaking, so we flash the sill pan and check the framing every time.

Glass That Earns Its Cost

Low-e glass with argon fill cuts the heat that pours through a west-facing slider in summer and the cold draft in winter. Impact-rated PGT and CGI units are available for storm country. Your written estimate names the exact glass package so you can compare it line by line against any other quote.

Sliding Door Replacement

Sliding Door Replacement swaps an aging slider for a new one, often in a fresh configuration such as a wider two-panel or a three-panel unit. It’s worth doing when the track is beyond repair, the seals have failed, or you simply want a door that glides with one finger. A standard sliding glass door replacement runs $1,500 to $4,500 installed, and larger or custom units run higher. For a full look at that work, read about our sliding glass door installation.

Vinyl, Fiberglass, and Aluminum

Vinyl is the most affordable and insulates well. Fiberglass costs more and holds paint and shape in extreme heat. Aluminum is slim and strong but conducts heat unless it has a thermal break. We lay out the trade-offs without pushing the most expensive option, and we can tell you which one suits your climate.

Tempered and Laminated Glass

Patio doors are large glass surfaces, so safety glass is a code requirement and not an upgrade. Laminated glass adds break-in resistance and cuts outside noise, which many homeowners notice on busy streets.

Sliding Door Installation

Sliding Door Installation is the work of setting a slider where there was none, or converting a window or a plain wall opening into a patio door. That means structural framing, a proper header, flashing, and a sill that drains water away from the house. New-opening installs usually run $3,500 to $9,000 because of the carpentry involved. Westlight Windows & Doors coordinates the framing and the finish work under one written price, so you aren’t chasing three trades.

Permits and Headers

Cutting a wider opening in a bearing wall requires a correctly sized header, and many areas require a permit. We explain what your local rules call for, build to those rules, and put the scope in writing. Skipping this step is the quickest way to a failed inspection when you sell the house.

Trim, Paint, and Cleanup

A finished install means interior casing, exterior trim, caulk, and a cleaned-up site. Our crews haul away the old door and glass, and the Kingswell Guarantee covers a clean job site as part of the deal.

Brands We Install

Westlight Windows & Doors installs patio doors from eight manufacturer lines. PGT and CGI supply impact-rated sliders and French doors for hurricane zones, and our crews know the anchoring patterns those ratings depend on. Therma-Tru is a strong choice for insulated fiberglass hinged patio doors, and ViewLux makes slim-profile units for wide views. ES Windows covers high-end architectural openings, ECO Window Systems focuses on energy performance, CWS handles high-wind products, and Mr-Glass is our source for tempered and specialty glass.

Having this many lines on hand means the right door gets matched to your home, your budget, and your weather. Your written estimate lists the door by name, the glass package, the hardware finish, and the trim, so nothing is vague.

Signs You Need a Pro Right Now

• The door fights you. A slider that takes two hands and a shoulder has worn rollers or a damaged track. Forcing it can crack the glass or bend the panel.
• You can see light or feel air around the edges. Failed weatherstripping or a settled frame lets conditioned air out and bugs in, and your utility bills show it.
• Fog between the panes. The seal is gone and the insulating gas has leaked. It won’t clear on its own.
• The lock doesn’t catch. If you can lift or jiggle a closed slider open from outside, your home is easy to enter. This one shouldn’t wait.
• Soft wood, stains, or water at the sill. Moisture is working into the framing. Rot spreads, and repair costs rise the longer it sits.

Our Process, Step by Step

1. 1
   Call and talk to a real person. When you call (903) 354-7134, a live person answers 24 hours a day. We ask what kind of door you have, what’s wrong, and book a visit in an arrival window that suits you.
2. 2
   We show up and measure. A background-checked, uniformed technician arrives in the window we gave. We measure the opening, check the sill and framing, and talk through what you want. No pressure.
3. 3
   You get a written price before any work. The estimate itemizes the door, glass, hardware, trim, and labor. That’s the Kingswell Guarantee in action: the price on paper is the price you pay.
4. 4
   Installation done right. We remove the old door, flash the sill, set and shim the new unit, seal it, and trim it out. The site is cleaned before we leave, and your written guarantee is handed over at the end.
5. 5
   365-Day Done Right Promise. If anything isn’t right within the guarantee period, call us. We come back and fix it at no charge, as we have since Owen Satterfield founded the company in 2009.
