AfterWindow Company in San Francisco, CA
Juniper Windows & Doors is a window company serving San Francisco, CA, focused on window replacement, window installation, and door replacement. San Francisco homes are not like homes in the East Bay or down the Peninsula. The housing stock is older, the lots are tighter, and the fog wants to find every draft. If you’re in a 1920s Marina flat or a 1960s Midcentury box in the Sunset, the right window is the difference between a living room that holds heat and one that needs a second sweater. Call us at (682) 281-2168 and we’ll talk through what your place actually needs.
Why San Francisco Homes Are Different
San Francisco’s mix of Victorians, Edwardians, Midcentury builds, and newer infill means there is no stock answer for window work here. A Marina District Spanish Revival and a Bernal Heights cottage face different wind loads, different sun angles, and different noise. Many homes in the Sunset, Richmond, and Noe Valley still have original single-pane wood sash windows, and those sashes lose heat fast when the marine layer rolls in off Ocean Beach. We also see a lot of aluminum-frame windows from the 1970s and 80s in Twin Peaks and Diamond Heights, where the fog corrodes aluminum tracks and makes sashes stiff. Terrain matters too: access to a rear bedroom window on a steep Russian Hill lot is not the same as a ground-floor storefront in the Mission. On top of that, many San Francisco properties sit inside HOAs or historic preservation overlays that require specific window styles and finishes. We check those details before quoting, so the price you see is the price on the permit application.
Our Main San Francisco Services
The two calls we get most in San Francisco are for replacing old windows and installing new doors, and each job tends to reveal the same local conditions: salt air, tight access, and decades of deferred maintenance. Here is what each service involves here.
Window Replacement in San Francisco
Replacing windows in San Francisco usually means pulling original or outdated units and fitting new frames into openings that are rarely square. We work with the house, not against it. For fog-belt homes in the Sunset, Richmond, and Parkside, we often recommend windows with a low U-factor, meaning the glass holds heat better. For west-facing rooms, impact-rated glass matters, and for Victorian homes in the Mission or Haight, we match sightlines so the window sits flush with the original trim. Pricing is always written first. See Window Replacement in San Francisco.
Window Installation in San Francisco
Window installation in San Francisco covers everything from new-construction windows in a rebuilt wall to retrofit units that slide into existing frames. Retrofit work is popular here because so many homes have stucco or shingle exteriors that owners want to leave untouched. We set window flashing correctly for San Francisco’s rainy winters, and we level sashes on floors that are rarely level. Access is a bigger factor than most people expect, especially on steep streets in Glen Park or Pacific Heights. See Window Installation in San Francisco.
Door Replacement in San Francisco
Door replacement in San Francisco is about more than swapping out a slab. Front doors here take fog, wind, and direct sun, and many entryways sit in enclosed alcoves that trap moisture. We replace door slabs, full prehung units, patio doors, and sliding doors, and we adjust hinges and thresholds for San Francisco’s shifting foundations, a quiet reality when a house has been settling for a century. For rear doors and garden-facing entries, we size and shim to older framing rather than forcing a square door into a trapezoid opening. See Door Replacement in San Francisco.

What pushes a price up in San Francisco is access, and access is rarely visible on the outside of a quote. A third-floor window reached only by a narrow stairwell, a rear door that needs a staging lift on a steep lot, or an HOA that only allows work during certain hours changes the labor equation. That is why we put the price in writing before anything starts, so there are no explanatory calls later.
