AfterTrusted Sliding & Patio Doors for Los Angeles Homeowners
Sliding and patio door replacement in Los Angeles typically runs between $1,800 and $6,400 installed, depending on the panel count, glass package, and whether the opening needs reframing. That’s the range we quote from most often at Sightline Windows & Doors, and it’s the number you should expect to see in writing before any work begins. Since 2012, we’ve installed and replaced our Sliding & Patio Doors in Los Angeles across every neighborhood, from Brentwood to Silver Lake to Sherman Oaks, and every job has started the same way: with a measured survey you keep and a written price that cannot change once the work is scoped. If your slider is sticking, leaking daylight at the edges, or letting in more street noise than it did five years ago, call (509) 265-6387 and we’ll schedule the survey.
What Our Sliding & Patio Doors Service Includes
Sliding and patio doors in Los Angeles homes do more than open and close. They’re the largest glass surface on most properties, they carry the heaviest daily cycle count of any door in the house, and they’re the first thing a buyer checks when a home goes on the market. Here’s what we handle, door by door.
Patio Doors
A patio door is any exterior door that opens onto a yard, deck, balcony, or courtyard. In Sliding & Patio Doors in Huntington Park and throughout Los Angeles, where indoor-outdoor living is the default, these doors get used year-round, which means the rollers, tracks, and locking hardware wear out faster than on any other door in the home. We replace the full unit when the frame is warped or the glass has failed, and we rebuild the rolling hardware when the panel itself is still sound. The survey we leave with you lists which parts we’re replacing, which parts we’re keeping, and what the labor on each line item costs.
Impact Sliding Glass Doors
Impact sliding glass doors are built with laminated glass and reinforced frames designed to hold together when struck by flying debris. In Los Angeles, they’re specified most often in hillside zones and canyon-adjacent neighborhoods where wind-driven debris is a real risk, but plenty of homeowners choose them for the noise reduction and the security rating alone. We install impact-rated sliders from PGT and CGI, and we specify the rating the opening actually needs based on its exposure, not the highest price point on the sheet. The written scope includes the impact rating, the design pressure number, and the glazing package, so you can verify what you’re paying for against the manufacturer’s documentation.
Sliding Glass Door Replacement
Sliding glass door replacement means removing the existing panel, track, and frame, then installing a new unit in the same or a slightly modified opening. You need this when the frame has rotted or corroded, when the glass seal has failed and shows permanent fogging, or when the door no longer locks securely. We measure the rough opening in six places, not two, because Los Angeles homes built between the 1950s and 1980s often have openings that have settled out of square. The replacement is ordered to those exact measurements, and the written price you approve is the price on the final invoice.
Impact French Patio Doors
Impact French patio doors are hinged, not sliding, and they come in pairs that swing inward or outward. They’re the right choice when the opening is wide enough to need two panels but the homeowner wants a wider clear passage than a slider provides. In Los Angeles, we see them most often on Spanish-style and Mediterranean homes, where the divided-lite look fits the architecture. We install impact-rated French doors from CGI and CWS, with the same design pressure documentation we provide on impact sliders, and we set the hinges and sweep seals to close tight against both air infiltration and water.
Screen Door Installation
Screen door installation covers both sliding screens on patio doors and hinged screens on French door openings. In Los Angeles, screens take a beating from sun exposure, pet claws, and constant use, and a torn screen on a patio door means you either leave the door closed or let the bugs in. We measure, cut, and install replacement screen panels in aluminum or fiberglass mesh, and we re-tension the rollers on sliding screens so they move without dragging. The photo record we leave after the visit documents the screen fit, the hardware condition, and any track issues we spotted while we were there.

Brands We Service for Sliding & Patio Doors
We specify and install ViewLux and PGT sliding door systems most often for Los Angeles homes, because both lines offer the glass packages and sightline options that hold up to coastal sun and canyon wind. ViewLux is our go-to when the homeowner wants the slimmest possible frame profile: their aluminum thermally broken sliders keep the sightlines clean while still delivering a measurable U-factor improvement over older bronze-framed doors. PGT we specify when the opening needs a documented impact rating, especially in hillside and wildfire-adjacent zones where the homeowners’ insurance carrier wants to see the design pressure number on paper.
We also work regularly with CGI and CWS product lines. CGI Windsor sliders are a strong mid-range choice for Los Angeles homes where impact glazing isn’t required but noise reduction and tight air sealing are, and we’ve installed enough of them to know their roller and lock hardware without opening the manual. CWS makes a solid aluminum patio door at a lower price point, and when a Sliding & Patio Doors - South Gate or West Adams homeowner needs a replacement that performs well without the premium glass package, that’s often what we quote. Whether you have a ViewLux, PGT, CGI, CWS, or any other make, we can service it or replace it with a documented spec that matches the opening.
BeforeAfterSigns You Need Sliding & Patio Doors Right Now
- The door needs two hands and a shoulder to move. Worn rollers and a sagging track create friction, and friction means you’re not using the door the way it was designed to be used. If the panel jumps the track or binds halfway, the hardware is done, and continuing to muscle it will eventually crack the glass or pull the frame out of square.
- You can see daylight at the edges when the door is closed. A gap at the top, bottom, or meeting stile means the weatherstripping has compressed or the panel has settled. In Los Angeles, that gap is blowing in dust and street noise during the day and letting conditioned air escape every night, which shows up on your utility bill within a month or two.
- The lock doesn’t catch, or it catches only when you lift the handle. A patio door that won’t lock is a security issue and an insurance issue. If the lock mechanism aligns only when the panel is lifted, the rollers are so worn that the panel sits low in the track, and that’s a hardware failure worth addressing before it becomes a break-in.
- Condensation forms between the glass panes. Fogging or moisture between the panes means the insulated glass unit’s seal has failed. There’s no repair for that, only replacement of the glass or the full door. We document the seal failure with a photo during the survey so you can see exactly what we saw.
- The frame shows visible corrosion, rot, or powdering at the bottom corners. Los Angeles’ coastal air and irrigation overspray eat at metal and wood frames from the bottom up. If you can push a flathead screwdriver into the jamb or the bottom rail feels soft, the frame is losing structural integrity, and the door won’t seal or secure correctly no matter how well the glass is holding up.
Our Sliding & Patio Doors Process - Step by Step
- 1
The measured survey. We come to your home and measure the opening at six points: top, middle, and bottom on both the height and the width. We also check the floor for level and the jambs for plumb, because a door hung in an out-of-square opening will never roll or seal correctly. You keep the survey document; it’s the basis for every number on the written quote that follows.
- 2
The written quote. The price is written down before any work starts, and the survey and the quote are the same document. Every line item is itemized: frame, glass package, hardware, installation labor, and any reframing or stucco repair the opening requires. There is no price-by-phone, no estimate in the salesman’s head, and no change order that wasn’t already in writing.
- 3
Product specification and order. We specify the glazing package by what the opening needs: impact-rated where the exposure calls for it, low-E and argon fill where the sun load calls for it, and a U-factor and SHGC number that we put on the quote. The door is ordered from the manufacturer to the exact rough opening measurements, not pulled off a warehouse shelf and shimmed to fit.
- 4
Installation and documentation. A background-checked, uniformed technician with a verifiable license number does the work. We set the frame level and plumb, bed the sill with a continuous seal, install the panel, adjust the rollers, and set the locking hardware. Then we photograph everything: the rough opening before, the flashing and sealing work, the finished door from both sides, and the hardware close-ups. That photo record is yours, included, no upsell.
- 5
The walkthrough and written warranty. We walk the door with you, roll it open and closed, lock and unlock it, and show you the maintenance points: track cleaning, roller adjustment, and weatherstrip care. You get the written workmanship warranty on paper, and the 365-Day Done Right Promise is stamped on the job under the Haven Standard: if it’s not done right, we make it right, no fine-print dance.
How Much Does Sliding & Patio Doors Cost in Los Angeles?
A standard two-panel sliding glass door replacement in Los Angeles runs $1,800 to $3,800 installed, depending on the frame material, glass package, and whether the existing opening needs any reframing. A three-panel slider or a wider multi-slide configuration runs $3,500 to $6,400. Impact-rated sliders from PGT or CGI add $1,200 to $2,500 over the base unit price, depending on the design pressure rating and the glass package. Impact French patio doors run $3,800 to $6,800 per pair installed. Screen door installation runs $180 to $400 per panel, including materials and labor.
Several factors move the price. The opening’s age and condition matters most: Los Angeles homes built before 1980 often have non-standard rough openings, settled headers, or stucco returns that require reframing or patching. The glass package is the second-biggest variable: basic clear insulated glass costs less than low-E with argon fill, which costs less than impact-rated laminated glass. Hardware tier matters too: a basic aluminum roller assembly runs a fraction of a stainless steel multi-point locking system. To avoid overpaying, get the spec in writing and hold the installer to it. Our written quote names the exact panel, glass, hardware, and labor line items, and the 365-Day Done Right Promise covers the work for a full year. If a competitor has already quoted you, bring us the estimate and we’ll review it at no charge under the Free Second Opinion clause of the Haven Standard.

Frequently Asked Questions - Sliding & Patio Doors in Los Angeles
A sliding or patio door is an exterior door, usually made mostly of glass, that opens horizontally on a track or swings on hinges to connect an interior room with an outdoor space. In Sliding & Patio Doors in Bell and throughout Los Angeles homes, these doors are typically the primary access point to a backyard, deck, balcony, or pool area. They’re sold in configurations from a basic two-panel slider to multi-slide and folding systems that stack entire walls of glass open.
A standard two-panel sliding door replacement takes one day from teardown to walkthrough. Custom-sized or impact-rated units take longer only because the door is ordered from the manufacturer after the survey, which typically adds two to three weeks of lead time. The installation itself, including any minor stucco or drywall patching at the opening, is still a single-day job in most Los Angeles homes.
A sliding patio door replacement in Los Angeles typically costs $1,800 to $3,800 for a standard two-panel unit and $3,500 to $6,400 for a three-panel or multi-slide configuration. Impact-rated glass adds $1,200 to $2,500, and impact French patio doors run $3,800 to $6,800 per pair. Call (509) 265-6387 with your rough opening dimensions and we’ll give you a written range before the survey, and a firm written price after it.
Yes, we install and replace PGT and CGI sliding door systems regularly across Los Angeles, and we’re familiar with both brands’ hardware, glass packages, and impact-rating documentation. We specify PGT most often for hillside and wind-exposed properties that need a documented design pressure rating, and CGI for homes where a mid-range impact or noise-reduction package makes more sense. We also work with ViewLux and CWS product lines.
Same-week installation depends on the door spec: if the opening matches a standard size and the glass package is one we can pull from a local distributor’s stock, we can often schedule the install within the week. Impact-rated and custom-sized doors are ordered from the manufacturer after your survey, so those carry a two to three week lead time. The survey is always the first step, and scheduling it doesn’t obligate you to anything except keeping the measured document we leave with you.
Every Sightline Windows & Doors installation is covered by our 365-Day Done Right Promise under the Haven Standard: if it’s not done right, we make it right, in writing and for a full year after the install date. The manufacturer’s warranty on the door itself runs separately and varies by brand and product line. Both warranties are delivered on paper at the walkthrough, not emailed as a PDF link six weeks later.
Clear a path from the entry door to the opening, move furniture and wall hangings at least four feet away from the work area, and take down any curtains or blinds mounted on the door itself. We lay drop cloths and run a HEPA vacuum at the end of the job, but the less there is near the opening, the faster the teardown goes. If you have pets, keep them out of the work zone during the install, and plan for the exterior access point to be blocked for most of the day. Call (509) 265-6387 if you want to walk through the prep over the phone before we arrive.
