What San Francisco Homeowners Say About Lightwell Windows San Francisco
Reviews tell you what a brochure can’t: whether the crew actually showed up on time, whether the price on the invoice matched the quote, and whether the job site looked better after the install than it did before. Around San Francisco, fog, marine air, and 100-year-old framing make window and door work unforgiving. We earn our reviews one opening at a time by doing the unglamorous things right: a written price before work starts, drop cloths down before tools come out, and a real person on the phone when you call with a question at 8 p.m. Here is what your neighbors in the Richmond, Noe Valley, and Bernal Heights have said after the last screw went in.
Recent Reviews
“We put off replacing three single-pane windows in our Outer Sunset flat for years because we dreaded the mess. The Lightwell crew laid drop cloths from the front door to the window bay, wore shoe covers the whole time, and sent a photo of the cleaned-up room before they pulled away. The new double-hungs are so tight that our heating bill dropped noticeably the first month. They even used a caulk that’s safe for our two cats, which my wife asked about three times.”
Dana N., Outer Sunset, San Francisco
“I had a door that had been sticking for a decade. Every contractor who looked at it gave me a different theory. Keith’s team diagnosed it in ten minutes, showed me the warped jamb with a level, and then explained exactly what the fix would cost before any work started. The written price was the price. No add-ons, no ‘while we’re here’ upsells. That alone earned my business for the next project.”
Kurt V., West Portal, San Francisco
“Our Victorian in the Mission had original windows that were beautiful but leaked cold air like a screen door. Lightwell let us choose from several brands, and they were honest that we didn’t need the most expensive one for a south-facing wall. The installers were background-checked and wore uniforms; I knew who was in my house before I opened the gate. When one sash needed a small adjustment a month later, they came back and handled it under the 365-Day Done Right Promise with zero debate.”
Marisol S., Mission District, San Francisco
“The fog in Glen Park settles right against our west-facing windows, so rot was starting on two sills. Lightwell replaced the windows and rebuilt the sills with proper flashing. The crew explained every step before they cut anything, asked before moving our planter boxes, and kept the noise down during our toddler’s nap. My daughter slept through the entire second day of the install. That’s not something you can put in a quote.”
Luis D., Glen Park, San Francisco
“I’ve hired contractors in San Francisco for thirty years. Lightwell is the first one that emailed me a line-item quote before I even committed, then stuck to it to the penny. They replaced a sliding glass door in our Marina condo, and when the crew left, the track was cleaner than it was before the job. The 365-Day Done Right Promise isn’t marketing copy; I called about a minor latch alignment and they scheduled the fix within days, no charge.”
Kurt V., Marina District, San Francisco
“Two bedrooms in our Sunset home were always five degrees colder than the rest of the house. Lightwell installed PGT windows with low-E glass, and the difference was immediate. But what impressed me most was the C.A.R.E. values the crew followed: they asked before moving a bookshelf, respected our quiet hours, and explained the final price before the install kicked off. When a question came up after hours, a real person answered the phone, not a recording.”
Dana N., Inner Sunset, San Francisco
