Fast, Reliable Patio Door Installation Across Florence-Graham
Patio door installation in Florence-Graham runs $1,400 – $4,800 for most single-door replacements, with sliding door repair typically landing between $280 – $700 depending on track, roller, and glass condition. Those are honest local numbers, not bait. The work itself is usually a one-to-two-day job once the permit is cleared. If you live in Florence-Graham and your rear slider sticks, leaks, or fogs between the panes, call (817) 686-2228 and we’ll put a written price in front of you before anything gets unscrewed.

We run crews into Florence-Graham every week. That matters here because this is unincorporated Los Angeles County, which means permits, inspections, and even header review follow County rules, not City of LA rules. Our installers know the difference and plan for it. Elliot Vance, who runs Meridian Windows & Doors, holds every job to the same standard: the price you approve is the price you pay, the permit gets pulled properly, and the work carries a written 365-day guarantee.
Why Meridian Windows & Doors Is Florence-Graham’s Preferred Patio Door Installation Company
Most Florence-Graham homeowners we meet have been through a bad install before, or at least a frustrating quote process. They call us because our Patio Door Installation team shows up when we say we will and puts every commitment on paper. That is not marketing language; it is how we are structured. Meridian is part of the Garrison Partners family, and every job, from a simple roller swap to a full rough-opening reframe, runs against The Garrison Standard: background-checked, uniformed technicians, a written price delivered before work starts, and a workmanship guarantee that covers a full year.
We answer the phone with a live person at (817) 686-2228, every day, around the clock. No voicemail loop. If you call from Florence-Graham, you get a real schedule, not a call-back promise.
Our Florence-Graham customers tend to own stucco bungalows from the 1930s through the 1950s, plus a fair number of converted rear-yard units. Those properties have specific failure patterns, which we’ll get into below. The point is that we know what we’re looking at when we pull a slider out of a County jurisdiction property, and our quotes account for what the inspector will actually check.
Sliding Door Repair in Florence-Graham
Sliding door repair in Florence-Graham usually means one of three things: the rollers have flattened or seized, the track has bent or rusted, or the glass unit has lost its seal and fogged. On many of the older stucco-and-furring homes here, there is a fourth failure: the jamb has swelled and the door binds because roof runoff has been pooling at the threshold for years. A repair on those homes typically runs $280 – $700, and we will not sign off on a fix that leaves the drainage problem in place.
Roller, Track, and Glass Work
Most roller replacements on a standard rear slider in Florence-Graham take under two hours on site. The bigger cost driver is the glass. If the insulated unit has fogged, the sash has to come out, the new unit gets ordered to size, and the repair becomes a half-day or full-day job. We stock common track and roller parts locally so we are not waiting on a shipment for basic repairs.
Water-Damaged Jamb Repair
When a rear door threshold sits below a flat or low-slope roof section, water finds its way under the track and swells the jamb over one or two wet seasons. Fixing the jamb is straightforward. Fixing the cause means extending or correcting the threshold flashing so runoff sheds away from the door. If we skip that second part, we’ll be back next winter and so will your leak. We would rather do it right once, and the 365-day guarantee means we are on the hook if it fails.
Patio Door Replacement in Florence-Graham
Patio door replacement in Florence-Graham starts with the question of whether the rough opening is still structurally sound. On 1930s and 1940s bungalows, especially around East Gage Avenue, Holmes Avenue, and the residential streets south of Florence Avenue, the original slider often sits in a stucco-furred wall with a rusted steel lintel hiding behind the finish. You cannot see that until the old door is out. That is also why we pull the County permit and schedule the inspection before we call the job done.
A standard replacement, where the opening is clean and no framing repair is needed, runs $1,400 – $2,800 in Florence-Graham. When the header is compromised, the lintel has to be replaced, or the opening has to be reframed for egress, the job moves into the $3,200 – $4,800 range. We give you that range in writing before work begins, and if the inspector requires something we could not see until demo, we stop, show you what we found, and re-price in writing before continuing.
Impact-Rated and Low-E Options
Florence-Graham gets hard afternoon sun off the rear yard, and many homeowners want low-E glass, which is a thin coating that reflects heat while letting light through. We also install impact-rated sliders from PGT and CGI. If your rear addition was built without a recorded permit, an impact-rated door sometimes helps satisfy egress and safety requirements when the County reviews the plan set. We will spec the right product for the opening, not whichever unit happens to be in the warehouse.

Rear-Yard Egress and Header Review
Many Florence-Graham lots have a rear second unit or a converted garage in the back. If the patio door you are replacing sits on that rear or side wall, the County will review it for egress width and header load. We check that against the County record before we order the door, so the scope does not shift mid-job. That pre-check is one of the things that separates a disciplined crew from one that finds out at inspection.
Trusted Brands We Service in Florence-Graham
We are authorized to install and replace products from eight manufacturers, and on Florence-Graham jobs we most often specify CGI and PGT for impact-rated work, ES Windows for mid-century and modern replacements, and ECO Window Systems when the priority is thermal performance on a budget. That matters because your patio door is not a one-size product, and the right spec here depends on sun exposure, security needs, and whether the County will require impact or egress ratings. We keep common parts for these lines moving through our Los Angeles-area supply chain, so Florence-Graham customers are not waiting on a slow special order for routine replacements. We also match existing doors to the brands already in the house whenever the original is still available.
Common Patio Door Installation Problems We See in Florence-Graham Homes
- Rusted steel lintels behind stucco. Homes built between 1930 and 1955 in Florence-Graham often have a steel header over the slider that has been rusting inside the wall for decades. A like-for-like swap that skips the header check gets flagged at inspection and turns a one-day job into a reframe.
- Rear roof runoff pooling at the threshold. Flat and low-slope rear roofs are common on the bungalows here, and they shed directly onto the patio door track during winter storms. The jamb swells, the track corrodes, and the leak recurs until the flashing is corrected.
- Unpermitted rear additions with no plan on file. If a previous owner converted a garage or added a rear unit without a recorded permit, the patio door’s rough opening may not match any plan the County has. We re-scope the job after pulling the County record, so there are no surprises when the inspector shows up.
- Fogged glass units in original sliders. The original insulated glass in a 40- or 50-year-old slider loses its seal and fogs between the panes. There is no cleaning fix for that. The sash or the glass unit gets replaced, and on many Florence-Graham homes it is cheaper in the long run to replace the whole door than to keep patching the same unit.

FAQs About Patio Door Installation in Florence-Graham
Yes. Florence-Graham is unincorporated Los Angeles County, so the permit comes through LA County Building & Safety, not the City of LA. Replacing a slider in an existing opening generally requires a building permit, and if the door is on a rear or side wall, the County will review it for egress width and header load. We pull the permit on every replacement and schedule the inspection before we close out the job. Call (817) 686-2228 and we’ll walk you through what the County will want to see on your specific block.
The leak is almost always coming from the threshold, not the glass. On Florence-Graham bungalows with flat or low-slope rear roofs, runoff sheds straight onto the door track, pools under it, and swells the jamb. The fix is to correct the threshold flashing and drainage so water sheds away from the door, then repair or replace the damaged jamb. We see this pattern constantly on homes south of Florence Avenue and around East Gage. Call (817) 686-2228 for an exact quote. Estimates are free.
Three things. First, rotted framing or a rusted lintel hidden behind the stucco. Second, a rough opening that does not match any County plan on file, usually because a rear addition or garage conversion was done without a recorded permit. Third, an inspector requiring impact-rated glass or egress reframing that was not part of the original scope. Our written quote calls these out in advance, and if we find something after demo, we stop and re-price in writing before continuing. The price does not creep silently on a Meridian job.
Yes, whenever the original product line is still available. We install and replace CGI, CWS, ES Windows, ECO Window Systems, PGT, Therma-Tru, ViewLux, and Mr-Glass products. If your home already has one of those lines in place, we can often match the door exactly rather than forcing a mismatched unit into the opening. If the original line is discontinued, we’ll spec the closest equivalent from the eight brands we carry and put the difference in writing before you approve it.
No, and any contractor who promises that is not telling you the truth. A permitted patio door replacement in Florence-Graham takes one to two days on site, plus time for the County to process the permit and schedule the inspection. Repairs like roller or track replacement can sometimes be done in a single visit. Full replacement involves demo, framing review, door set, flashing, and inspection. The calendar is what it is. We’ll give you a realistic schedule when you call (817) 686-2228 for a free estimate.
