Lennox is its own animal. It’s an unincorporated LA County enclave, which means every window permit and inspection runs through the County’s Department of Building and Safety, not a city hall. We’ve been through that process enough times to know exactly what the County plan checker wants to see before we touch a single opening. That saves you days, not hours.

Why Barrett & Sons Construction Is Lennox’s Preferred Windows & Doors Company

Tom Barrett started this company in 1998, and his sons run the crews that show up on Lennox jobs. That’s not a slogan. When you call, a live person answers. When we quote a window job, the price is in writing, and if anything changes scope, you get a written change order before work moves forward.

We’ve pulled County permits for window and door replacements all over Lennox, from the older postwar bungalows near Lennox Park to the small apartment buildings along Inglewood Avenue. Local homeowners tend to ask the same questions: will the County flag my unpermitted sunroom when they inspect the windows, and how do I handle that without ripping everything out. We’ve walked that road often enough to answer honestly before you sign anything.

Every job carries our 90-Day Done Right Promise in writing. If something’s not right, one call brings Tom back. That’s the whole point of a name on a truck.

Our Windows & Doors Services in Lennox

Window Installation in Lennox

We install new windows in Lennox homes built in the 1940s through the 1960s, where original wood sashes are warped, painted shut, or missing weatherstripping entirely. If you’re also considering a Lennox Kitchen Remodeling project, we can coordinate timelines so both trades aren’t fighting for parking on the same narrow street. The coastal air here doesn’t help. We measure every opening carefully because many of these older stucco bungalows have settled frames that are no longer square. A rushed measurement means a sloppy fit and a drafty window that rattles every time a plane takes off from LAX.

Door Installation in Lennox

Front doors, rear doors, security doors, and interior passage doors. Homes in Lennox often have original hollow-core doors that have been through 60 years of humidity from the marine layer, and they’ve warped enough that the latch no longer catches. We replace those and hang new exterior doors with proper thresholds and weather seals that hold up to the morning fog that rolls in off the coast May through August.

Window Replacement in Lennox

Most Lennox replacements are full-frame jobs because the original window openings have settled and the old aluminum frames are pitted from decades of salt-laden air. We remove the old frame down to the rough opening, correct the rough opening to square or as close as the framing allows, flash it correctly, and set the new window. Every opening gets new exterior trim and insulation. No inserts over rotted jambs, no shortcuts the County inspector would flag.

Impact Windows & Doors in Lennox

We install impact-rated windows and doors for Lennox homeowners who want hurricane protection without the hassle of plywood and shutters. Brands like PGT and CGI carry Miami-Dade approval, and they replace your standard glass with laminated assemblies that stay in one piece if debris hits them. In a neighborhood directly under the LAX approach path, that matters. Impact windows also cut the noise from departures and arrivals dramatically, which is a side benefit most Lennox homeowners appreciate more than they expected.

Trusted Brands We Service in Lennox

We carry and install Simonton, Ply Gem, and PGT windows and doors, plus CGI for impact-rated openings. These are names you can look up. Simonton makes a solid vinyl window that handles the coastal moisture here without pitting. PGT dominates the impact category. If you have a specific brand or model in mind, tell us during the estimate and we’ll spec it. We don’t stock mystery brands off a van and we don’t push a brand just because we got a better deal on it this quarter.

Common Windows & Doors Problems We See in Lennox Homes

• Fogged double panes from failed seals. The temperature swings between the marine layer mornings and the afternoon sun cause the seal between panes to fail, leaving moisture trapped inside the glass. The fix is replacement, not a fog-cleaning service.
• Aluminum frame corrosion. Salt-laden air from the coast eats through older aluminum window frames faster than people expect. You’ll see white chalky pitting along the bottom rail first. Those frames lose their structural integrity, and the operable sashes stop sealing.
• Sliding patio doors that jam. The original rollers in 1950s and 1960s sliders in Lennox are worn flat, and the tracks are filled with years of grime and rust. A good cleaning can temporarily help, but replacement rollers and a new track are often the real fix, and sometimes the whole door is at the end of its life.
• Warped entry doors. The coastal moisture swells original wood doors every morning, and they never fully shrink back by evening. Homeowners notice the deadbolt no longer lines up with the strike plate. A new properly sealed door solves that permanently.
