Window Installation services near you in San Francisco means a crew that shows up on time, puts a written price in your hand before any work starts, and leaves your home cleaner than they found it. That’s how Lightwell Windows San Francisco operates. You’ll reach a live person at (831) 480-4124, day or night, and get honest guidance on whether a window needs replacing or a simpler fix will hold. We serve homeowners from the Sunset to Noe Valley, along with Castro Valley, Danville, Berkeley, San Leandro, Walnut Creek, Burlingame, and Piedmont.
A light well is what brings daylight deep into a building, and that is what a well-installed window should do for your home. Keith Yamada leads our team, and every job carries the 365-Day Done Right Promise: if it’s not done right, we make it right. No debate, no countdown. Just a commitment to the work.
What Window Installation Costs in San Francisco
Most window replacements in San Francisco run between $700 and $1,800 per opening, depending on the window style, the frame material, and what the existing opening looks like once the old unit comes out. A full-home replacement in a typical Marina or Glen Park house, which might mean 8 to 15 windows, usually lands between $8,000 and $22,000. Those are honest ranges, not teaser numbers. You get a written price before any work starts, every time.
Here is how the cost breaks down by window type-such as 3-Panel Sliding (3-Lite Roller) Windows-in the San Francisco market:
- Single-hung or double-hung vinyl: $700 – $1,200 per window installed. The most common choice for older row houses and flats.
- Casement or awning windows: $900 – $1,500 per window installed. Popular in Bernal Heights and Noe Valley for better airflow control.
- Sliding windows: $800 – $1,400 per window installed. A good fit for wide openings in mid-century homes around the Outer Sunset.
- Picture or fixed windows: $1,000 – $1,800 per window installed. Maximizes the fog-bank views from Pacific Heights and Twin Peaks.
- Bay or bow windows: $2,500 – $4,500 per window installed. Common in Victorian-era homes in the Mission and Haight districts.
Several San Francisco-specific factors move the price. Many homes sit on hillsides, which can make exterior access tighter and slower. Older Victorians and Edwardians often have non-standard rough openings that need careful reframing. And if you live in a historic district, the Planning Department may require specific window styles and materials, which shifts both the product choice and the timeline. We walk you through all of this during the estimate, and the number we put in writing is the number you pay.
Fast, Local Window Installation
When a broken window is letting fog in or an old frame won’t lock, you need a response measured in hours, not weeks. We schedule most window installation estimates within 48 hours, and for urgent jobs, like a shattered pane on a ground-floor window or a window that won’t close, we prioritize same-day and next-day visits. A live person answers (831) 480-4124 24/7, so you’ll never sit through a voicemail maze while your living room fills with cold air.
Installation itself typically takes one to two days for most single-family homes. Larger projects, like replacing every window in a three-story Victorian, can run four to five days. We’ll tell you the exact timeline before we schedule the crew, and quiet tools are used during nap hours when that matters to your family.
The Lightwell Difference, Measured in What You Can See
Every crew that walks through your front door follows the C.A.R.E. values. That’s not a slogan we hang on a wall; it’s a checklist each technician works from on every visit. Clean up like it’s our own home: shoe covers and drop cloths go down before any tool comes out, and we photograph the cleanup before the crew leaves. Ask before we move or touch anything: your furniture stays where you put it unless you say otherwise. Respect the family’s time and quiet hours: we schedule around school drop-offs, nap schedules, and work-from-home calls. Explain the price before the work: the number you approved is the number on the final invoice.
If you have kids or pets, which most San Francisco homeowners do, this matters. We use pet-safe caulk and sealants wherever there is a choice, and we keep small hardware, broken glass, and debris off the floor and out of reach. You’ll know who is at your door before they knock because every technician is background-checked and arrives in uniform.
Eight Window Brands, Chosen for Your Home, Not Our Inventory
We’re the local, independently operated Cedarwell windows-and-doors company serving San Francisco, and we carry eight manufacturer brands: PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. That range matters. A foggy coastal home in the Outer Richmond needs different glass than a sunny hillside house in Portola. A Victorian with original trim needs different frame profiles than a sleek 1960s box in Diamond Heights. Because we’re not tied to one vendor, the recommendation fits the home.
Every project is backed by the Cedarwell Care Promise and the 365-Day Done Right Promise. If the finished work is not right, we make it right. That’s the whole sentence. No fine print, no time limit beyond the year, no “well, technically” conversation. Just a standing rule that has operated since 2010.
Why San Francisco Homes Need Different Window Thinking
San Francisco’s microclimates are real, and they change block by block. A house in the Outer Sunset might see 50 days of heavy fog a year, while a house in the Mission gets real afternoon heat. Awning & Hopper Windows and other styles that work for one might underperform for the other. We account for that when recommending products: laminated glass for wind-driven rain, low-E coatings for sun exposure, and tighter air seals for homes on windy ridge lines like those around Twin Peaks and Diamond Heights.
Older homes bring their own set of considerations. Many San Francisco homes built before 1950 have weight-and-pulley sash systems or single-pane glass that lets heat pour out through the frame. Replacing those with Bay & Bow Windows or other modern styles often involves reframing the rough opening to handle a modern, insulated unit. We check lead paint requirements during the estimate and handle the process correctly rather than cutting corners around it.

Areas We Cover
Our home service area includes all of San Francisco, from the Richmond and Sunset on the west side to Bayview and Visitacion Valley on the east, plus Noe Valley, the Castro, the Mission, Glen Park, Pacific Heights, and the Marina. We also regularly install windows in surrounding communities: Castro Valley, Danville, Berkeley, San Leandro, Walnut Creek, Burlingame, and Piedmont. If you’re unsure whether we cover your specific street, call (831) 480-4124 and ask. A person answers, and they’ll tell you straight.
What to Expect on Installation Day
Here is the sequence, plain and simple:
- Arrival and walkthrough. The lead technician walks the job with you before anything starts. You confirm the scope, the window locations, and the price one more time.
- Floor and furniture protection. Drop cloths go down, shoe covers go on, and furniture near the work area gets moved only if you approve it.
- Old window removal. The old unit comes out carefully, and we contain any dust or debris rather than letting it drift into the room.
- New window installation. The new unit is set, leveled, insulated, flashed, and sealed. We use pet-safe products at the sealant stage.
- Cleanup and photo. The crew cleans the work area, vacuums, and photographs the finished cleanup. You see the result before we leave.
- Final walkthrough. We show you how the window operates, confirm you’re happy with the work, and leave you the written warranty information.
Most single-window installations take four to six hours. A full-house project runs a few days, and we’ll give you a day-by-day plan before we start.
