ES Windows Bathroom Remodeling: The San Francisco Owner’s Guide
An ES Windows bathroom remodeling project in San Francisco typically runs $10,620 – $33,040 installed, depending on scope, window count, and whether we’re replacing the window or building around it. Most ES Windows bathroom jobs finish in 2 to 4 weeks once materials land. The way homeowners usually find us: they’ve got condensation between the panes, a crank handle that spins without moving the sash, or frame rot creeping up from fog-driven moisture along the Outer Richmond or Sunset corridors.
We carry ES Windows-compatible hardware and have installed enough of these units across San Francisco to know exactly what fails on them and what does not. If your window is fogged, sticking, or leaking at the frame, the fix usually comes down to whether the sash is worth saving or the whole unit needs to come out. Straight number, real scope, no surprises at close-out.
Which ES Windows Models This Applies To
ES Windows makes a handful of series lines, and the bathroom unit you have is almost certainly one of three: the ES 5000 series (older aluminum frames, common in 1990s San Francisco remodels), the ES 7000 series (vinyl, double-pane, the workhorse of early 2000s projects), or the ES 8000 series (newer vinyl with better thermal breaks). Each series uses different balance hardware and sash profiles, so a part from a 5000 will not drop into an 8000. That matters when a homeowner buys a replacement balance online and hands it to us on install day.
To identify your window, check the label on the top edge of the sash or the inside of the frame. ES Windows embeds a code that starts with the series number, then a size in inches, then a two-letter color code. If the label is gone, measure the visible glass width and height to the nearest 1/8 inch and snap a photo of the corner joint. We can usually identify the series from the corner weld style alone. On OEM versus aftermarket: ES Windows OEM balances and cranks are still available for most series, but lead times run 3 to 6 weeks. Quality aftermarket equivalents from Caldwell or Truth Hardware fit many ES units and ship in days. We’ll give you both paths and a written price for each before you decide.
Styles & brands we work with
Signs Your ES Windows Bathroom Remodeling Is Failing
- Condensation between the panes. The seal between the two glass lites has failed. In San Francisco’s fog-heavy neighborhoods like the Sunset and the Richmond, seal failure on ES 7000 units happens faster than the manufacturer’s 20-year rating suggests, often by year 12 or 14.
- Hard cranking or a handle that spins free. The operator gear inside the crank mechanism is stripped, or the hinge arm has come out of its track. This is the most common ES Windows bathroom failure we see, especially on casements that get opened daily for shower steam ventilation.
- Water staining at the sill or wall below the window. Either the weep holes are blocked, or the frame caulking to the rough opening has failed. In older San Francisco homes with balloon framing, that water travels and shows up ten feet away from the window.
- Frame rot at the bottom corners. ES 5000 aluminum frames don’t rot, but the wood buck they’re mounted into does, especially in homes without proper flashing. Once that substrate goes soft, the window will not operate square no matter what hardware you replace.
- Cold draft even when the sash is closed. The weatherstripping has compressed or the lock isn’t pulling the sash snug against the seal. We see this on ES units that face the ocean side of the Richmond, where the salt air accelerates weatherstripping breakdown.
Replacement Cost & What’s Included
Here is what a San Francisco ES Windows bathroom remodeling project looks like on price:
- Single ES window hardware replacement (balance, crank, or lock): $470 – $2,125 installed, parts and labor included.
- Glass-only replacement for a fogged ES sash: $590 – $2,950 depending on glass size and Low-E coating.
- Full window replacement within a bathroom remodel: $5,310 – $17,700 depending on series, size, and whether we’re reframing the opening.
- Bathroom remodel with ES Windows work included: $10,620 – $33,040 for the full project scope.
What drives the range: window count, whether the rough opening needs reframing, whether we’re pulling a permit (city of San Francisco requires one for window replacement in most cases), and whether tile or surround work is in the same project. Every line item goes on a written price before we start. No numbers move at the door. The work carries our 365-Day Done Right Promise: if anything we touched fails within the first year, we come back and fix it at no charge.

You can safely check a few things yourself: clean the weep holes with a toothpick if water is pooling in the track, tighten visible screws on the crank handle, and check that the sash is seated square in the frame. If the handle still spins or the window still sticks, that’s a balance-tension or operator-gear problem. The springs inside ES Windows balance assemblies are under high tension. We’ve seen what happens when they let go: sliced hands, broken glass, and a sash that suddenly weighs more than you expect while you’re holding it. That’s a trained-professional repair, not a weekend project.
If the frame itself has rot or the glass is fogged, the unit needs to come out. That’s where a DIY job turns into a water intrusion problem you won’t find until next winter. Call (831) 610-5598 and we’ll send someone who has pulled ES units out of San Francisco walls for two decades.
FAQs
In San Francisco’s climate, ES Windows seals typically last 12 to 18 years before fogging shows up, and the mechanical hardware lasts 15 to 25 years depending on how often the window is opened and how much salt air it faces. Windows on the ocean-facing side of the Richmond and Sunset wear out faster than those in Noe Valley or the Mission. If your unit is past year 15 and showing two or more failure signs, replacement usually costs less in the long run than chasing individual repairs. Call (831) 610-5598 and we’ll tell you which side of that line your window is on.
Yes, in many cases. We can remove the sash, replace the insulated glass unit, and reinstall it without touching the frame. If the frame is also failing, glass replacement alone won’t fix the problem. The question is whether your ES frame has enough life left to justify putting new glass in it. We’ll tell you straight either way.
A hardware-only repair runs 1 to 2 hours on site. A glass-only sash replacement takes 1 to 3 days depending on glass fabrication. A full window replacement within a bathroom remodel runs 2 to 4 days for the window portion, with the overall remodel timeline depending on the full scope. We’ll put the schedule on the written scope document before any work begins.
We keep the most common ES Windows balance assemblies, crank operators, and weatherstripping on our trucks, which means many hardware failures get fixed the same day. Less common parts, especially for ES 5000 series units, may need to be ordered from the manufacturer or pulled from our aftermarket suppliers. Either way, you’ll know the lead time and price before we schedule the visit. Call (831) 610-5598 for a free estimate.
