Why Meridian Windows & Doors Is Lennox’s Preferred Patio Door Installation Company

Homeowners across Lennox call us because we put the price on paper before anyone touches a wall. That’s not a slogan. It’s how we’ve run every job since 2009 under The Garrison Standard. Elliot Vance leads our team, and he’s particular about one thing above all: the written price does not move at the door. If you’ve had a contractor quote one number and bill another, that’s exactly the problem we built this company to avoid.

Our technicians are background-checked and uniformed. When they show up on Felton Avenue or Eucalyptus Drive, you know who’s walking through the door. We stock parts for Lennox’s older housing stock, and we’re authorized to install and replace products from CGI, CWS, and Therma-Tru among our eight manufacturer lines. Every installation carries the 365-Day Done Right Promise in writing. If something fails within that year, we come back at no charge. No fine print about labor exclusions.

Sliding Door Repair in Lennox

Sliding Door Repair in Lennox usually means fixing a door that sticks, drags, or won’t lock because the jamb behind 1950s stucco has absorbed decades of marine moisture. The fix can be as simple as replacing rollers and realigning the track for around $180 to $320, or as involved as pulling the frame, sistering rotted framing, and resetting the opening for $500 to $900. We tell you which one you need before you pay anything.

Track and Roller Rebuilds

Most Lennox sliders ride on aluminum tracks that have been sand-blasted by years of grit blowing off the Sepulveda corridor and LAX approach paths. We pull the panel, inspect the rollers, and tell you honestly whether the hardware is salvageable. When the rollers are shot, we replace them with sealed units that don’t seize up when the marine layer settles in every June.

Jamb and Weatherstripping Replacement

If the door wiggles in the frame or you can see daylight around the edges, the weatherstripping has compressed past useful life. We replace it with dense rubber bulb seals that hold up to the daily expansion and contraction Lennox’s coastal air brings. This typically runs $140 to $260 and makes an immediate difference in drafts and noise from planes out of LAX.

Patio Door Replacement in Lennox

Patio Door Replacement in Lennox is rarely a one-for-one swap. Homes here were built on tight lots, many before 1960, and the original rough openings often sit out of square by a half inch or more. We measure the actual opening, not the existing door’s visible dimensions. A complete replacement with a new Therma-Tru or CGI sliding unit runs $2,400 to $6,800 depending on glass package, opening width, and how much framing correction the jamb needs.

Full-Frame Replacement with Stucco Work

This is the job we do most often on Lennox Boulevard and the side streets off it. We cut back the stucco, remove the old door and frame, sister any rotted framing, square the opening, set the new unit, flash the sill properly, and patch the stucco to match the wall. The goal is a door that opens with one hand and seals against the afternoon onshore wind, not one that binds again by next spring.

Insert Retrofit Where the Frame Is Sound

Sometimes the original wood frame is still solid, and we can set a new door panel directly into the existing jamb with minimal disruption. This saves $600 to $1,100 on labor and stucco work. We won’t recommend it if the frame shows any sign of rot or racking. A retrofit into a bad jamb is a waste of your money and our reputation.

Trusted Brands We Service in Lennox

We install and repair patio doors from a portfolio that includes CGI, CWS, and Therma-Tru, among eight manufacturer lines. That matters in Lennox because the coastal air and LAX-adjacent wind exposure mean a door should be spec’d with laminated glass interlayer and a design pressure that matches the actual jamb condition. A stock catalog number won’t do it. We order the right panel for the opening, and we keep common parts local so repairs don’t stall waiting on freight from a distributor across the country.

Common Patio Door Installation Problems We See in Lennox Homes

• Rotted framing hidden behind stucco. Homes built in the 1940s and 1950s have wood jambs that absorbed decades of marine moisture. A new slider set over that framing binds again within a year, and the homeowner thinks the door is the problem. It wasn’t.
• Non-standard rough openings. Past remodels left Lennox homes with door widths that don’t match any catalog size. Ordering a stock panel leaves gaps someone fills with foam instead of flashing properly. That’s a water intrusion risk we won’t leave behind.
• Sill water damage from slab elevation. Many original patio slabs in Lennox sit below exterior grade, so rainwater flows toward the door instead of away. Without a proper sill pan and drainage plane, the new door rots from the bottom up.
• Racked 6-foot openings. We regularly find openings that have settled a half inch out of square. A door set into that racked opening will never roll smoothly until the framing is corrected. It’s structural work, and it requires a permit in Lennox.

We replaced an aging aluminum slider on a 1950s stucco home near the corner of Lennox Boulevard and Felton Avenue where the original 6-foot opening had racked and the jamb was saturated. Our crew cut back the stucco, sistered the framing, and set a new Therma-Tru sliding unit with a low-E insulated glass unit and laminated glass interlayer on the street-facing panel. We flashed the sill, patched the stucco to match, and walked the homeowner through the permit inspection sign-off before closing out. The door seals against the wind and doesn’t stick, even on damp mornings.
