AfterWindow Company in Belmont, CA
Juniper Windows & Doors is the window company Belmont homeowners call when they want a written price before the work begins and a real person on the phone when they call. Most window and door projects in Belmont run between $650 and $2,900 per opening depending on size, product line, and how the existing frame has held up against Peninsula moisture. We install impact-rated glass, replacement windows, and entry doors across Belmont, and every job is covered by the 365-Day Done Right Promise. Call (682) 281-2168 for a straight answer and a free estimate.
Why Belmont Homes Are Different
Belmont sits on a hill-and-flatland mix, which means window and door work here is rarely one-size-fits-all. Homes in the flats around Old County Road and Harbor Boulevard tend to be ranch and split-level builds from the 1950s and 1960s with original wood frames that have spent decades absorbing morning fog and afternoon salt air. Homes up in the hills, especially around Hallmark Drive and Ralston Avenue toward Carlmont, get real wind exposure and stronger afternoon sun, which shortens the life of cheap weatherstripping and makes low-E glass worth every dollar.
Zoning in Belmont is strict on exterior changes, and many streets fall under hillside review rules, so door and window projects often need permits pulled before the first screw turns. We handle the permit paperwork on our Belmont jobs. What matters most to us is that our crews are used to Belmont’s older rough openings: they’re rarely square, sometimes not even close, and that’s where you find out whether a window company actually knows what it’s doing. We do.
Our Main Belmont Services
Belmont homeowners call us about three things more than anything else: swapping out old single-pane windows, putting new windows into additions or remodels, and replacing doors that have warped or lost their seal. Each service has its own Belmont page with pricing, timing, and permits laid out in plain detail.
Window Replacement in Belmont
Replacing windows in Belmont usually means pulling original 1960s aluminum or wood sashes and setting new double-pane units into the existing openings. The goal is a tighter seal and lower U-factor (how much heat passes through the glass). Belmont’s foggy mornings are unkind to old seals, and failed seals are the number one sign a window is due. We measure, order, pull permits if the openings are being altered, and install with new insulation and trim. Get full pricing and process details on Window Replacement in Belmont.
Window Installation in Belmont
New construction or additions need windows set into fresh framing, which means flashing, waterproofing, and a different sequence of installation than replacement work. Belmont hillside projects almost always need engineered specs for wind load, and our crews work directly with the framing contractor or GC to keep the schedule moving. We install PGT, CGI, CWS, and ES Windows products for new builds and remodels around town. See Window Installation in Belmont for the full rundown.
Door Replacement in Belmont
Front doors in Belmont take a beating from the marine layer and afternoon sun, and we replace more warped, sagging, and drafty doors in this city than nearly any other single job. A new Therma-Tru or ViewLux entry door tightens the home’s envelope, improves curb appeal, and usually pays back in energy savings within two or three years. We also handle slider and French door replacements. Details and pricing are on Door Replacement in Belmont.

Belmont prices run higher than flat inland cities for one main reason: access. Hillside homes, tight side yards, and the need for permits on exterior changes all add labor to the job. You’ll always get a written price from Juniper before any work starts, and that number is locked.
