AfterFast, Reliable Window Replacement Across Calabasas
Window replacement in Calabasas usually costs between $900 and $2,800 per opening installed, and most full-home projects on the canyon side run $18,000 to $55,000 depending on glazing and design pressure requirements. The work typically takes two to five days once permits clear. If you’re reading this from a Mulwood or Calabasas Hills home with original single-pane sashes, you’re likely dealing with exactly the wind and heat exposure we see on nearly every job here. Call (817) 686-2228 for a written scope and price on your specific windows before you commit to anything.
We know this city’s building department, its WUI map, and which elevations on your lot take the worst of the Santa Ana winds. That local knowledge changes what gets specified, what passes inspection, and what your final invoice looks like. A meridian is a fixed line you measure everything against. That is what the name means and how we run every install in Calabasas.
Key Takeaways:
- Single-window replacement in Calabasas runs $900 – $2,800 installed; full canyon-side homes run $18,000 – $55,000.
- Canyon-exposed lots need design pressure ratings and glazing that flatland homes don’t.
- Every price is written down before work starts, and it does not move at the door.
- Covered in writing for 365 days. If it fails, we come back at no charge.
Why Meridian Windows & Doors Is Calabasas’s Preferred Window Replacement Company
We’re the windows-and-doors specialist inside the Garrison Partners family, held to The Garrison Standard since 2009. In Calabasas, that means a crew that shows up in uniform, background-checked, with the exact window spec already written for your elevation. Homeowners here have dealt with enough no-shows and door-price changes to be skeptical. We answer that skepticism with paper: a written price before any work begins, and a 365-Day Done Right Promise on every installation.
We stock and install eight manufacturer lines: PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. That’s not a catalog flex. On a canyon-facing Calabasas lot, the right unit is often a CGI or PGT product with a specific design pressure rating. On a flat Calabasas Park street, a ViewLux or ECO Window Systems unit may be the better value. The point is the spec matches the exposure, not whatever happens to be sitting in a warehouse.
Our phones are answered by a live person 24 hours a day, every day. You call, you get a human who can talk about your windows, not a voicemail loop. Dispatch and scheduling are coordinated from our Los Angeles office; crews serve Calabasas locally.
Elliot Vance leads the operation. He built the Calabasas crew around one rule from The Garrison Code: show up when you say you will, write the price before you start, and stand behind the work in writing. Nobody on our crew will park a truck on your lawn, leave sill caulk smeared, or hand you a change order because they “didn’t see that coming.” If the jamb is rotted, we note it in the written scope before the first screw turns.
Window Repair in Calabasas
Window repair in Calabasas is what we do when the glass, hardware, seal, or frame has failed but the opening itself is still sound. A failed insulated glass unit, a spring balance that snapped, a sash that won’t stay up, a weather seal gone brittle from canyon sun. Repair work typically runs $175 to $650 per window depending on whether we’re replacing glass, rebalancing the sash, or rebuilding the weather seal. If the frame is rotten or the wall shows water damage, repair stops being the honest answer and replacement becomes the conversation.
Glass and Seal Replacement
The most common repair call we get in Calabasas is a blown double-pane, especially on west and canyon-facing elevations that take direct afternoon heat. When the seal fails, moisture fogs the glass and the insulating gas escapes. We replace the insulated glass unit rather than the whole window when the sash and frame are still square and sealed to the wall.
Sash and Hardware Repair
Older wood and aluminum sashes in Calabasas homes, particularly 70s and 80s construction, lose their spring balances and tilt-latch hardware over time. We replace balances, locks, and rollers on single-hung, double-hung, and sliding windows. If the sash itself is cracked or the track is warped, we’ll tell you straight and quote the replacement instead.
Call (817) 686-2228 for a repair scope and written price. If a repair fails inside the guarantee period, the second visit is free.
Window Replacement Company in Calabasas
Window replacement company work in Calabasas means pulling the old unit, inspecting the jamb and rough opening, correcting any rot or settling, installing the new window, re-flashing the exterior, and patching back stucco or trim. A single opening typically runs $900 to $2,800 installed. Full-frame replacement on an average Calabasas home runs $18,000 to $42,000, and canyon-exposed homes with upgraded glazing and higher design pressure ratings run higher, sometimes up to $55,000 or beyond on large custom openings.
Full-Frame vs. Insert Replacement
Full-frame replacement removes everything down to the rough opening, including the old jamb and exterior trim. We do this when water has gotten into the wall, the jamb is rotted, or you’re changing the window size. Insert replacement leaves the existing frame in place and fits a new window inside it, which works when the frame is square and dry, and costs less.
Vinyl and Energy-Efficient Upgrades
Vinyl replacement windows are the most common spec in Calabasas because they handle the dry heat without warping and they take low-E coatings well. Low-E glass is a thin coating that reflects heat while letting light through. On canyon lots, we often pair low-E with laminated glass interlayers for wind-borne debris protection, which also quiets the wind noise along Mulholland and the 101 corridor.
We are the Window Replacement team that Calabasas homeowners call when they want the scope written before the work starts. Every opening gets inspected, measured, and priced on paper.
Trusted Brands We Service in Calabasas
We’re authorized to install and replace products from PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. For Calabasas canyon homes, we regularly spec PGT and CGI units because their design pressure ratings match what the local wind-load review requires. For interior and flat-lot replacements, ViewLux and CWS often deliver the better balance of cost and thermal performance. Because we stock local parts and have direct manufacturer channels, turnaround on Calabasas orders runs two to three weeks on standard units, faster if the spec is already in the warehouse.
We’re part of the Garrison Partners network, which means our Calabasas customers get the same written guarantee and the same live-person phone coverage as every other city in the network, but with a local crew that knows this specific building department and its WUI map. That matters when the inspector shows up on a hillside lot off Piuma Road.
Common Window Replacement Problems We See in Calabasas Homes
- Canyon wind fatigue and seal failure. Homes along the Mulholland corridor and hillside streets off Las Virgenes take sustained wind that flexes cheap sashes and kills seals early. We see failed seals on builder-grade units as young as eight to ten years in these spots.
- Stucco flashing failures on hillside construction. Calabasas hillside homes are mostly stucco over wood frame. If the original flashing was lapped wrong or the stucco wasn’t keyed into the jamb, the first winter rain finds its way in. By the time we open the wall, the rough opening needs real repair, not just a new window set in place.
- Low design pressure units on canyon-facing elevations. Some past contractors ordered standard flatland windows to save $40 a unit. Those fail the wind-load review now required for WUI and canyon-exposed lots, and the homeowner pays twice: once for the wrong window, once for the right one.
- Uneven settling in Calabasas Park and Mulwood. Homes built in the 70s and 80s on graded hillsides settle unevenly. Sashes bind, locks misalign, and the opening goes out of square. A proper replacement job accounts for that before the new window goes in, not after.

All of it goes in the written scope before work starts. Call (817) 686-2228 for a free estimate with real numbers for your specific windows.
Calabasas sits in a high-wind and wildfire-exposed canyon corridor where most Las Virgenes-area homes fall under WUI and wind-driven code scrutiny. That means window replacement here is typically specified with enhanced design pressure and tempered or laminated glazing rather than builder-grade units used one city over in the San Fernando Valley flats. If you’re on a canyon-facing elevation, this is the single biggest driver of your window cost, and it’s the first thing we check on the written scope.
Our crew recently replaced a full run of single-pane, wood-sash double-hung windows on a 1980s two-story home in Mulwood, swapping in CGI vinyl units with low-E insulated glass units and laminated glass interlayers on the canyon-facing elevation. The original jambs had swelled and lost their weather seal, letting heat and wind-driven dust in. After resetting the jambs, shimming the new sashes, and re-flashing the exterior, the homeowner had a tighter, more efficient envelope and a visibly quieter canyon-facing wall.

FAQs About Window Replacement in Calabasas
Yes, most window replacements in Calabasas require a permit through the city’s building department, and the inspection covers weatherproofing, flashing, and the glazing and design pressure ratings required for your WUI zone. We pull the permits, coordinate the inspection, and don’t call the job done until the inspector signs off. Call (817) 686-2228 if you want to know what applies to your specific lot before you commit.
A full replacement in Calabasas runs like this: we measure every opening (including checking for settling and out-of-square jambs), write the scope and price, pull the permit, order the units, remove the old windows, repair any jamb rot or water damage, install the new windows with new flashing, patch back stucco or trim, and schedule final inspection. Two to five days of on-site work is typical once the windows are in hand. You get a written scope before any of it starts.
If we open the wall and find rotted framing, failed flashing, or a rough opening that’s badly out of square, that repair work adds to the invoice. That’s why our written scope includes a visual and, where possible, invasive check before the full bid is locked. We’re not going to surprise you at the door with a change order. Call (817) 686-2228 for a scope that accounts for the common failure modes we see in Calabasas hillside construction.
On-site work for a full Calabasas home runs two to five days. The permitting process typically adds two to four weeks, and custom units with laminated glass or high design pressure ratings add two to three weeks of manufacturing time. A realistic full timeline from signed scope to final inspection is four to eight weeks. We’ll give you a calendar before we start, not after.
Yes, especially on west and canyon-facing elevations. Low-E insulated glass units reduce solar heat gain enough to take real load off your AC during Calabasas summers, and laminated glass on canyon walls also cuts wind noise. The exact savings depend on your existing windows, your orientation, and your HVAC, but the thermal difference is measurable on the first hot week after install. Call (817) 686-2228 and we’ll spec the glazing that matches your actual sun and wind exposure.
