Window Company in Lennox, CA
Window and door work in Lennox comes down to two things: the coastal air and housing stock that includes a lot of mid-century stucco homes built before modern energy standards. Juniper Windows & Doors handles replacement, installation, and door work across Lennox with written pricing before anything starts and a 365-day guarantee on the finished job. Whether you’re chasing a draft in a 1950s bungalow or replacing a fogged double pane, call (682) 281-2168 and we’ll give you a number you can plan around.
Why Lennox Homes Are Different
Lennox sits close enough to the coast that salt air and marine haze work on window frames, seals, and door thresholds all year. Homes here skew older – a large share were built between the 1940s and 1970s – so we regularly see aluminum frames that conduct heat, original single pane glass, and door jambs that have settled out of square. Those older stucco exteriors also mean every rough opening is slightly different, so a Lennox window job tends to need more shimming and flashing adjustment than a cookie-cutter tract home would.
Summer heat in Lennox is moderate but inland air pushes through in late summer, and old single pane windows let that sun drive indoor temperatures up fast. On the other side, winter nights near the coast bring damp air that finds every worn weatherstrip. Lennox homeowners don’t need windows built for snow loads, but they do need frames and seals that shrug off salt, and glass that actually insulates. That pushes us toward products like impact-rated PGT windows and well-sealed Therma-Tru door systems rather than builder-grade off-the-shelf units.
Our Main Lennox Services
Lennox homeowners call us most often for two things: replacing aging windows and installing new doors that seal tight. Each service has its own Lennox page with pricing and specifics.
Window Replacement in Lennox
Old aluminum and single pane windows are the biggest comfort problem we see in Lennox. Swapping in modern double pane glass changes the temperature in a room on day one, and it quiets the traffic drone near the 105 and Century Boulevard. Every replacement starts with measuring the actual rough opening, not the old frame, because 60-year-old stucco homes never line up square. Window Replacement in Lennox covers what the process looks like, ballpark costs, and how long a typical job takes.

Window Installation in Lennox
New construction and addition work in Lennox mean installing windows into fresh openings. That’s a different job than replacement – you’re flashing and sealing a new rough opening rather than working around an existing frame. Lennox’s proximity to the coast means we use sealants and flashing rated for salt humidity, and we set windows so any wind-driven rain drains away from the opening. Window Installation in Lennox walks through what new installs involve and what the typical price looks like.

Door Replacement in Lennox
Lennox doors take a beating from coastal moisture and daily use. We replace entry doors, patio sliders, and French doors, and the job usually includes reworking the threshold and jamb so the new door sits level and seals against drafts. Doors on older Lennox homes frequently need shim work and exterior trim repair before the new slab goes in. Door Replacement in Lennox breaks down the options and what you should expect to spend.

Lennox’s older frames and coastal exposure are the two things that most often push a job to the higher end of the range – rotted sills, nonstandard rough openings, or salt-damaged flashing all add labor.
