Fast, Reliable Window Replacement Across Calabasas
Window replacement in Calabasas usually means more than swapping glass; it means matching the city’s fire-severity-zone glazing requirements, navigating HOA approvals, and getting a written price before demolition starts. Juniper Windows & Doors handles all three, with upfront pricing and a 365-day workmanship promise. If you’re weighing a full-frame replacement or a simpler insert job, call (682) 281-2168 and we’ll scope it properly.
We know Calabasas streets well enough to plan for the details others miss: stucco walls that change flashing details, afternoon sun that kills cheap seals, and association design guidelines that can stall a project if nobody checks them first. Our crews work across Mulwood, Calabasas Hills, The Oaks, and neighborhoods off Mulholland Highway and Las Virgenes Road. Local knowledge here is not a nice-to-have; it is the difference between a job that passes inspection the first time and one that drags on for weeks.
Why Juniper Windows & Doors Is Calabasas’s Preferred Window Replacement Company
Founded in 2001 as part of the Relay Home Co. family, Juniper focuses on windows and doors only. No remodels, no unrelated trades, no subcontractor roulette. Calabasas homeowners deal with background-checked, uniformed technicians on every visit, and every project starts with a written price, not a ballpark that shifts once the crew arrives. The 365-Day Done Right Promise covers parts and labor for a full year after installation, in writing.
Sean Mackey leads our Calabasas work with a simple rule: quote the job as if it were his own house. That means checking whether the existing wall is stucco or siding before pricing flashing and trim. It means confirming the HOA submittal path before ordering glass. It means telling a homeowner honestly when a window can be repaired instead of replaced. Calabasas residents regularly tell us that kind of straight talk is rare, and it is why they refer us to neighbors along Park Ora, Paseo Primario, and Cold Canyon Road.
Window Glass Repair in Calabasas
Window Glass Repair in Calabasas most often means replacing a failed insulated glass unit on a window whose frame is still square and solid. We remove the old sash, order a new dual-pane unit matched to the home’s design pressure and glazing spec, and reset it cleanly. A typical Calabasas glass-only repair runs $180 to $340 per unit, depending on size, glass type, and whether the sash needs new weatherstripping.
Blown Seals and Fogging
A foggy window in Calabasas is almost always a blown seal, and the fix is a new insulated glass unit, not a whole new window. We order the replacement IGU from our local suppliers and usually have it on-site within a week. The repair takes under an hour per sash.
Cracked or Impact-Damaged Panes
For cracked annealed glass in the fire-severity zone, we routinely upgrade the replacement to tempered or laminated glass rather than putting the original fragile spec back in. That small change brings the window closer to current code and often costs only $40 to $90 more per pane.
Window Pane Replacement in Calabasas
Window Pane Replacement in Calabasas is a single-pane job: the frame stays, the glass comes out, and a new pane goes in with fresh glazing and points. We see this most often on older homes near Old Topanga Canyon Road and the Calabasas Highlands, where single-pane wood windows are still common. Expect $120 to $260 per pane for standard glass, with tempered or laminated upgrades priced slightly higher.
Single-Pane to Dual-Pane Upgrades
When a wood frame allows it, we can often convert a single-pane sash to a dual-pane insulated unit, which cuts heat gain and noise noticeably. The pane itself runs $160 to $320, and we verify the sash’s load capacity before recommending the upgrade.
UV Fade and Solar Gain Reduction
West-facing panes in Calabasas take brutal afternoon sun, and a standard clear pane lets UV through that fades furniture and flooring fast. We stock Low-E and tinted replacement panes, including ViewLux laminated options, that reduce that damage without darkening the room to a cave.
Trusted Brands We Service in Calabasas
We install and service Window Replacement products from PGT, CGI, CWS, and ViewLux, along with four other trusted lines. That means a Calabasas homeowner with an existing PGT impact window does not have to wait weeks for a matching part from a distant distributor. Our local supply relationships keep common glass packs, balances, and hardware in regional stock, so a repair or replacement moves faster than it would through a big-box special order.
Common Window Replacement Problems We See in Calabasas Homes
- Stucco walls hiding old flashing failures. Homes built in the 1980s and 1990s around Mulwood and Calabasas Hills often have aluminum windows set directly into stucco with caulk instead of a proper flashing system. By the time a homeowner notices water staining or a sticking sash, the rough opening usually needs re-flashing before the new window can go in.
- Annealed glass in a fire-severity zone. Calabasas sits inside a designated high-fire-hazard area, so code expects dual-pane tempered or laminated glass on most elevations. We regularly see previous replacements that cut corners with standard annealed panes, which then fail the homeowner’s insurance inspection or crack under heat stress.
- HOA color and finish conflicts. Calabasas has more than a dozen active homeowner associations with design review rules. We have seen homeowners order beautiful windows in a finish their HOA board then rejects, forcing a costly reorder. Our scoping step includes pulling the association’s finish schedule before anything gets ordered.
- Sticking or loose sashes from shifting ground. Homes along the hillsides above Las Virgenes Road and Cold Canyon Road sit on expansive clay that moves seasonally. That movement racks window frames out of square, and a replacement has to be shimmed and squared carefully or the new sash will bind within a year.
Pricing for Window Replacement in Calabasas, CA
An insert window replacement in Calabasas, where the old frame stays and a new sash unit is dropped in, typically runs $650 to $1,400 per opening. A full-frame replacement that tears out the old jamb, re-flashes the rough opening, and sets a new frame costs $1,100 to $2,800 per opening. Glass-only repairs land between $150 and $450 per pane depending on whether the unit is tempered, laminated, or standard dual-pane. The biggest cost drivers are wall type (stucco costs more than siding), glass spec (impact-rated adds 15 to 30 percent), and whether the opening needs rot repair. Every Calabasas job gets a written line-item quote before we order a single part, and that number does not move unless you change the scope. Call (682) 281-2168 to schedule a free estimate.

FAQs About Window Replacement in Calabasas
Yes, window replacements in Calabasas generally require a permit through the city’s building department, and the work must pass a final inspection. Like-for-like insert replacements where the opening size does not change are sometimes simpler to permit than full-frame swaps, but we pull permits on every job that requires one and handle the inspection scheduling. Call (682) 281-2168 and we can confirm how permitting applies to your specific home before quoting.
Calabasas sits inside a high-fire-severity zone, which triggers building code requirements for dual-pane tempered or laminated glass on many elevations, especially near property lines and on large glazed openings. Tempered glass breaks into small rounded pieces instead of dangerous shards, and laminated glass holds together even when cracked, which matters a great deal during a wind-driven fire event. Our quotes default to the spec your home actually requires, so you won’t get a surprise reorder notice mid-project.
Often yes, especially in communities like The Oaks, Calabasas Hills, and Mountain View Estates where design review boards govern exterior colors, window styles, and even muntin patterns. Juniper pulls the association’s finish schedule and submittal requirements at the scoping stage, then submits the window specs for approval before ordering. That step alone has saved our Calabasas clients thousands in reorder fees and weeks of delay.
Most Calabasas window replacements run 2 to 5 weeks from the first measurement to final inspection, with the install itself usually done in one to three days. HOA approval, custom color orders, and impact-rated glass fabrication add time at the front end. We give you a real calendar at the quote stage, and your written price stays fixed so long as the scope doesn’t change.
Three things can change the price once work begins: unexpected rot or termite damage in the rough opening, a stucco repair that goes beyond the original flashing allowance, and an HOA or city requirement that surfaces after demolition. We photograph everything during demolition and send you a written change order with a specific dollar figure before any additional work proceeds. You approve the number, or the work doesn’t happen. Call (682) 281-2168 for an exact quote on your Calabasas home; estimates are free and the number you get is the number you’ll pay unless you change the job.
