Window Company in Calabasas, CA
Meridian Windows & Doors handles window replacement, window installation, and patio door installation across Calabasas, CA. Most homeowners here call us for two reasons: older windows that fight the summer heat, and patio doors that no longer glide. Calabasas homes carry a specific set of conditions – stucco exteriors, canyon-facing lots, strict HOA design rules – that make window and door work different from a typical tract-house swap. We write every price down before work starts and back the labor for 365 days. Call (817) 686-2228 to get a free estimate on your Calabasas home.
Why Calabasas Homes Are Different
Calabasas, CA sits in a climate band where summer afternoon temperatures routinely push into the 90s while nights drop fast once the marine layer settles in. That swing puts real stress on window seals and door frames. Homes in neighborhoods like Calabasas Park, Mulwood, and The Oaks were largely built between the late 1970s and early 2000s, which means many original aluminum-frame windows are now hitting forty years old. Aluminum conducts heat, and in a Calabasas August that heat moves straight through the frame and into the house.
The terrain adds another layer. Homes on canyon-facing lots off Mulholland Highway or Las Virgenes Road get direct afternoon sun with little shade, so low-E glass (a thin coating that reflects heat while letting light through) makes a measurable difference in cooling cost and comfort. Stucco exteriors, which dominate Calabasas, require careful flashing and seal work around any new window or door opening. And if you’re in a gated community or an HOA-governed neighborhood, board approval is often required before you change window styles or door finishes. We’re used to that paperwork and we’ll help you prepare the specs the board wants to see.
Our Main Calabasas Services
Most Calabasas homeowners reach out about replacing old windows or installing a patio door that finally opens without a fight. Each of these services has its own dedicated page below.
Window Replacement in Calabasas
Replacing windows in Calabasas usually means pulling out original aluminum frames and setting in modern units with better glass and tighter seals. The job matters here because heat and UV exposure are relentless from June through October. We measure, order from the manufacturer line that fits the home’s style, and handle the install, trim, and stucco patch in one visit. Expect a written price before any work begins. Details on glass options, frame materials, and local pricing are on the Window Replacement in Calabasas page.

Window Installation in Calabasas
New construction, additions, and remodels in Calabasas call for window installation from scratch. We work from your plans, coordinate rough-opening sizes with your contractor, and install windows that meet Calabasas code for egress and energy performance. Many of these projects are in newer builds along Cold Canyon or in renovations in the guard-gated communities off Parkway Calabasas. We’ll spec the right window for the opening based on orientation and wind exposure, not whatever is on a shelf. Read the full breakdown on the Window Installation in Calabasas page.

Patio Door Installation in Calabasas
Calabasas backyards open onto pools, patios, and canyon views, which makes the patio door the most-used opening in many homes. Sliding doors that stick, French doors that sag, or a wall where a new door should go – we handle all of it. The tricky part in Calabasas is the combination of stucco walls and the wide temperature swings that make frames shift through the year. We set doors level, seal them tight, and make sure they lock clean. See the specifics at Patio Door Installation in Calabasas.
