If you have an ES Windows product with a failed or failing part, we stock ES Windows-compatible hardware and install it for most San Francisco homes for between $220 and $680 per opening, depending on the component and what we find when we open the frame. Keith Yamada and our crew carry common ES Windows rollers, balances, weatherstripping, and locking hardware on the truck, so a single-part repair is usually done in one visit. Most owners discover a problem the same way: a sash that suddenly drags against the track, a lock that no longer catches, or a window that drops an inch when you let go. The part behind that behavior is specific, and matching it correctly is the difference between a window that works for another decade and one that binds again in six months.
Which ES Windows Models This Applies To
ES Windows manufactures aluminum-framed window and door systems, and we regularly work on their sliding, casement, and fixed window lines across San Francisco. The compatibility detail that matters most: ES Windows uses metric-profile hardware on many of its aluminum series, so a standard American-market roller or balance from a big-box shelf will often sit too loose or too tight in the track. We match parts by the stamped code on the sash corner or the edge of the frame, then confirm with a caliper measurement before ordering or pulling from van stock.
For older ES Windows installs, we lean toward OEM parts when the frame is still square and the original hardware lasted well. For newer units where a specific roller or latch has failed early, we often recommend a quality aftermarket equivalent that addresses the original weak point, such as a stainless-steel roller bearing instead of nylon. Either way, you’ll see the part number and the price in writing before we touch anything.
Styles & brands we work with










Signs Your ES Windows Window Installation Is Failing
- The sash drags or chatters when you slide it. The roller wheels have flat-spotted or the nylon bearing has worn down. In San Francisco’s marine air, fine grit off the ocean works into the track and accelerates that wear.
- The window drops when released. A block-and-tackle or spiral balance has lost tension or snapped internally. Left alone, the frame can rack and the glass seal can fail.
- The lock spins or won’t engage the keeper. The internal cam has stripped or the keeper moved out of alignment. This is also the moment to check that the sash is still seating square in the frame.
- You feel air moving around the sash even when closed. The weatherstripping has compressed past recovery or torn away from the carrier. In a Sunset District home, you’ll feel this on the first foggy morning.
- Condensation between the panes rather than on the room side. The insulated glass unit has lost its seal. The hardware might still be fine, but the sash needs to come out to replace the IGU, which is the time to swap worn parts too.

AfterReplacement Cost & What’s Included
For ES Windows window installation work in San Francisco, most single-part replacements run between $220 and $680 installed. A roller or latch replacement on one sash sits at the lower end. A full balance replacement with new weatherstripping and track cleaning lands mid-range. If the sash needs to be removed, reglazed, and reinstalled with new hardware, you’re at the upper end.
Every quote is a written line-item price before work begins. That number includes the part, the labor to remove and reset the sash, adjustment for a square close, and cleanup with drop cloths under the work area and shoe covers on every entry. We don’t hand you a different number at the end. The work is covered by the 365-Day Done Right Promise, which means if the window doesn’t operate the way it should within a year, we come back and make it right.
DIY or Call Us?
There’s honest work you can do yourself: pull the loose debris out of the track with a vacuum, wipe the frame down, and note where the sash binds or sticks. That note saves us a diagnosis step when we arrive.
Where we’d say stop: the balance system. Window balances hold stored tension, and releasing one incorrectly can snap it into the frame or into your hand. On ES Windows aluminum frames, the sash is also heavier than most people expect, and pulling it out without supporting the corners will bend the frame lip. That turns a $300 part replacement into a full sash rebuild. If the window drops, drags, or won’t stay up, call us at (831) 480-4124 and we’ll diagnose it in place before we remove anything.
FAQs
Rollers and weatherstripping on ES Windows aluminum frames typically last 12 to 18 years in San Francisco, though ocean-adjacent homes in the Richmond and Sunset Districts see faster wear from salt-laden air and constant fog moisture. Balances often outlast rollers by a few years, and locks fail most often from repeated forcing against a misaligned sash.
Some components can be cleaned and re-lubricated, but a flat-spotted roller, a torn balance cord, or a stripped lock cam cannot be repaired back to reliable function. We’ll tell you if a cleaning and adjustment is enough before we quote a replacement. Call (831) 480-4124 and we’ll walk through what you’re seeing.
Most single-sash window installation repairs on ES Windows products take 45 to 90 minutes once the sash is out. If we need to order a specific OEM part, we’ll quote you a one-week turnaround and keep you posted.
Yes, we carry common ES Windows rollers, balances, locks, and weatherstripping profiles on the truck, plus compatible hardware for PGT, CGI, and CWS systems we service. If your part isn’t on board, we measure and order the exact match rather than make something close fit.
If your ES Windows window is dragging, dropping, or letting the fog in, call (831) 480-4124 for a free estimate. We’ll tell you what failed, what it costs to fix, and what it will take to keep the rest of the frames working. Measure it until it’s boring, then cut once.
