What Sliding Glass Door Installation Includes

Sliding glass door installation means removing the old patio door, or cutting a new opening, and setting a new door panel and frame so it rolls smoothly, locks tight and keeps water and air out. A complete job covers the measurement, the removal of the old unit, the sill pan and flashing, the frame set and shim, the glass panels, the lock hardware, the interior and exterior trim, and the haul-away. Most homeowners call when the old door has become hard to slide, when the glass has fogged, or when a draft keeps finding its way across the floor. Westlight Windows & Doors handles the whole job with one crew, so there is no handoff between a door seller and a separate installer. Every project carries the Kingswell Guarantee: written price, committed arrival window, clean job site and a written guarantee.

Replacement or New Opening

Most installs are replacements, where the new frame goes into the same rough opening as the old one. That is the quickest path and usually the lowest price. A new opening, such as converting a window into a patio door, means cutting the wall, framing a header and finishing the siding and drywall around the door. We tell you which path your house needs at the estimate, and the written price spells out every part of it.

Frame Type and Panel Layout

Standard sliders have one fixed panel and one panel that rolls. Larger openings, like 12-foot walls of glass, use two or three moving panels or a pocket design that tucks the glass into the wall. We measure the opening, check that the header can carry the span, and recommend the layout that fits how you actually use the room.

When to Replace Your Patio Door

A patio door that fights you every time you open it is not just annoying, it is a sign that something has worn out. Rollers flatten, tracks dent and the frame can drop out of square as the house settles. Replacing the whole door makes sense when the damage is in the frame or the glass seal, because new rollers cannot fix a bent track or a fogged double pane. We will tell you honestly if a roller swap and a new set of weatherstrips will do the job, and we will tell you just as plainly when a new door is the better value. Owen Satterfield has had our crews give that straight answer since 2009.

Rollers, Tracks and Frames

Roller wear is the most common complaint, and a worn roller can chew into an aluminum track within a season or two. Once the track is gouged, a new roller will never glide the way it should. If the frame itself has racked or rotted at the bottom corners, the door has to come out.

Fogged Glass and Failed Seals

Fog between the panes means the seal around the insulated glass has failed and the gas fill has escaped. The glass stays cloudy for good, and the door loses most of its insulating value. On older sliders, replacing the whole door usually costs only a little more than a new glass unit, and you end up with a fresh frame as well.

Sliding Glass Door Materials and Frames

The frame material decides how the door looks, how long it lasts and how much it costs. Vinyl is the most common choice for a patio door because it resists moisture, never needs paint and keeps heat transfer low. Aluminum is slim and strong, which suits large spans and modern homes, though it conducts heat unless the frame has a thermal break. Fiberglass holds its shape in extreme temperatures and takes paint well. Wood-clad units offer a warm interior look but ask for more upkeep. Westlight Windows & Doors installs all of these through our eight manufacturer lines, and your written estimate names the exact frame, glass package and hardware so you know precisely what is going into your home.

Glass Packages That Matter

Low-e coatings reflect heat, so the room stays cooler in summer and warmer in winter. Argon gas between the panes slows heat flow further. Tempered glass is required for doors by building code, and laminated glass adds security and noise reduction. Homes in storm-prone areas often need impact-rated glazing, and we install impact-rated PGT and CGI doors for exactly that purpose.

Hardware and Locks

A good slider has a multi-point lock, a sturdy latch and stainless or sealed rollers. Cheap hardware is where many budget doors fail first. We list the lock and roller type in the estimate, because a patio door is one of the most common entry points for break-ins and the lock deserves attention.

Sliding Doors Versus French and Hinged Patio Doors

Sliding doors save floor space because the panel moves along a track instead of swinging into the room. That makes them a smart fit for tight patios, narrow decks and rooms where furniture sits close to the opening. French doors and hinged patio doors give a wider clear opening and a classic look, but they need room to swing and a bit more clearance outside. We install both styles, and if you are torn, we bring samples and talk through traffic, furniture and view before you choose. For a related project, see our Window Replacement page, since many homeowners update the windows beside the patio door in the same visit and match the look across the back of the house.

Pocket and Multi-Panel Systems

Wide openings of 10 feet or more can use multi-panel sliders that stack to one side or disappear into a pocket in the wall. These systems cost more and need careful structural work, but they open an entire wall to the yard. We handle the header sizing and the finish carpentry as part of the same written price.

Screens and Blinds

Most sliding doors ship with a full-height screen that rides on its own track. Between-the-glass blinds are also available on some lines and keep the cords and dust away from the panel. Tell us what you want when we measure and it goes on the estimate.

Brands We Install

Westlight Windows & Doors installs products from eight manufacturer lines. We work with Therma-Tru for door systems known for tight seals and durable finishes, and with PGT and CGI for impact-rated sliders in regions that see hurricanes and high winds. ES Windows brings high-end architectural looks that suit custom homes, and CWS supplies strong, wind-rated units. ECO Window Systems is a regular choice when energy performance is the priority, and ViewLux offers slim sightlines for homeowners who want as much glass as possible. Mr-Glass covers tempered and specialty glass needs. The point of carrying this many lines is simple: the right door gets matched to your home, not the other way around.

Sliding Glass Door Installation Cost Factors

Price depends on the size of the opening, the frame material, the glass package and the amount of carpentry the old door left behind. A standard 6-foot vinyl slider with double-pane low-e glass sits at the low end. An 8-foot unit with laminated or impact-rated glass costs more, and a multi-panel wall system costs more again. Rot found under the old threshold, damaged framing or stucco and siding repair around the opening can add to the total, which is why we inspect the rough opening before we give you a number. Whatever the project, the figure on your written estimate is the figure on your final bill.

What Can Raise the Price

Impact ratings, custom colors, wider spans, tall openings and second-story installs all add cost. So does repairing water damage under the sill. If we see damage when the old door comes out, we stop, show you, and put any added work in writing before we continue.

Where You Can Save

Staying with the same opening and the same panel layout keeps labor down. Choosing a stock size and color instead of a custom order shortens the wait and trims the price. We will point out the sensible savings, and we will tell you where cutting corners would cost you later.

Signs You Need a Pro Right Now

• The door sticks, scrapes or jumps the track. Worn rollers and a damaged track make a door hard to move and easy to knock off its rail. Forcing it can crack the glass or bend the frame.
• Fog or moisture between the panes. The seal has failed and the insulating gas is gone. The cloud never clears on its own.
• You feel a draft or hear outside noise. Compressed weatherstripping or a racked frame leaves gaps that let air, dust and sound in, and your heating and cooling bills climb.
• The lock no longer holds. A latch that does not catch or a door that lifts off its track is a security risk. Do not wait on a patio door that can be forced.
• Soft wood, stains or water at the threshold. Water getting under a door rots the subfloor and the wall framing. The longer it goes, the more the repair costs.

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, 7 days a week. We ask about the door you have, what is going wrong and when you want the work done.

   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 frame, glass and layout. No pressure.
3. 3
   You get a written price before any work. The estimate itemizes the door, glass package, hardware, trim and labor. The price on the paper is the price you pay.
4. 4
   Installation done right. Our crew removes the old door, sets a sill pan, flashes and shims the new frame, checks the roll and the lock, and cleans the site before leaving. You get a written guarantee on the finished work.
5. 5
   365-Day Done Right Promise. If anything is not right within the guarantee period, call us. We come back and fix it at no charge. That promise has been our standard since Owen Satterfield founded the company in 2009.
