Window replacement in Kensington, CA typically runs $850 – $2,800 per opening depending on the unit, the frame condition, and where your house sits on the hill.

Why Juniper Windows & Doors Is Kensington’s Preferred Window Replacement Company

We’ve replaced windows on enough Kensington homes to know the hills change everything. A quote that works for a 1920s bungalow near Colusa Circle doesn’t transfer to a 1960s split-level further up the Arlington grade. The wind exposure, the afternoon sun, the age of the framing, the condition of the stucco returns: all of it affects the right product and the honest price.

Our Kensington customers call because they want the number in writing before anyone touches a screw. Every Juniper project starts with a written price, then a booking link with a live arrival time, crew photos when work starts, and a digital invoice at the end. Sean Mackey set that standard, and our installers, background-checked and uniformed, work to it on every single job. If the installation isn’t right, the 365-Day Done Right Promise covers it, parts and labor, in writing, for a full year.

We serve Kensington from our San Francisco Bay Area office with crews who know Kensington’s blocks, its permits, and its exposure zones. You won’t get a call center runaround. You’ll get a live person on the phone, any hour, and a crew that shows up when the tracker says they will.

Window Replacement Company in Kensington

A Window Replacement Company in Kensington is doing more than swapping glass. The job starts with measuring rough openings, checking the jambs and sills for rot, confirming the design pressure your specific lot requires, and then pulling the right permit from Contra Costa County. That’s the only way the finished window fits, operates, drains, and passes inspection. When a Kensington homeowner notices worsening drafts, moisture between glass panes, sashes that stick or won’t stay open, or condensation that never dries, replacement is typically more cost-effective than repeated repairs. Expect $1,100 – $1,900 per opening for a full-frame replacement on a standard double-hung, and $850 – $1,500 for an insert when the existing frame is sound.

Full-Frame vs. Insert on Kensington Homes

Full-frame replacement removes the entire old window, including the jambs and exterior trim, down to the rough opening. We recommend it when rot is present, when the original frame is out of square, or when you want to add new-construction flashing around the opening. Kensington’s older wood-framed homes, particularly the stucco-sided ones, often hide sill damage behind layers of trim that an insert would never address.

Insert replacement, sometimes called a pocket window, fits a new window inside the existing frame. It’s faster and less invasive, and it keeps your interior and exterior trim untouched. On a 1950s ranch along Arlington Avenue in Kensington we swapped original aluminum single-panes for low-E insulated glass units with a laminated glass interlayer in the west-facing sliding doors. The homeowner’s main complaint was a hot living room by 4 p.m. and a policy renewal that needed documentation on the openings, so we matched the design pressure stamped on the original permit and provided an airtight unit spec sheet for their agent. Cooling-side comfort improved noticeably the first summer, and the crew left the jambs and sashes intact because the frames were still square.

Vinyl and Energy-Efficient Upgrades

Vinyl replacement windows remain the most common choice in Kensington because they handle the marine layer’s moisture without warping or requiring paint. Energy-efficient upgrades, typically low-E coatings and argon or krypton gas fills, drop the U-factor and cut heat gain on west-facing elevations. On a Kensington lot where the afternoon sun hits hard from the bay side, a low-E package can reduce cooling load enough that the HVAC runs noticeably less from July through October.

Window Glass Replacement in Kensington

Window Glass Replacement in Kensington means replacing only the sealed glass unit, or the individual pane, without replacing the frame. This is the right call when a single pane cracks, a seal fails and fog builds between the panes, or a bedroom window needs tempered safety glass to meet egress code. Glass-only replacement in Kensington runs $350 – $750 per pane for insulated units, with laminated or impact-rated glass pushing toward $900 – $1,400 depending on size and spec. If the frame is still square and the operation is smooth, glass replacement gets you clear views and a sealed unit at roughly a third the cost of a full window.

When Glass Replacement Makes Sense

A fogged double-pane window on a shaded north wall in Kensington rarely needs a whole new frame. The seal has failed, the insulating gas has leaked out, and the glass unit itself needs replacing. We order a matching low-E insulated unit, swap the glass, and you keep your original trim and paint line intact.

However, glass replacement cannot fix a rotted sill, a warped sash, or a frame that has shifted out of square. In those cases the money spent on new glass buys temporary relief, not a fix. The honest answer on a Kensington home with aging wood windows is sometimes a full-frame replacement, and we’ll show you why with photos and measurements before you spend anything.

Trusted Brands We Service in Kensington

We install and service windows from CGI, CWS, and ES Windows, three product lines that hold up to Kensington’s coastal wind and hilltop sun. If you have a CGI impact-rated window that’s fogged, or ES Windows units on a modern Kensington remodel that need matching replacements, our crews order the correct parts without guesswork. We keep common components in local stock for Kensington jobs, which means less waiting on a freight shipment and a faster path from measurement to installation. Our team specs the right product for each opening, not whatever’s on sale that week.

Common Window Replacement Problems We See in Kensington Homes

• Split wind-exposure specs on one lot. Kensington’s hillside lots straddle two wind-exposure zones on the same block, so a house on a ridge line can be scoped for a higher design pressure than a lot 300 feet below it. Hom
