Casement Windows in San Francisco, CA
Casement windows hinge at the side and crank open outward, and in San Francisco they’re a practical choice for two reasons: they seal tighter than sliding windows when closed, and they catch the bay breeze when open. A casement window replacement in San Francisco typically runs $900 to $2,400 per window installed, depending on size, frame material, and whether the existing opening needs repair. Meridian Windows and Doors San Francisco provides Window Installation services and replaces casement windows across the city, from the Richmond to Noe Valley, with a written price before any work begins and a 365-day guarantee on every job.
If you’re replacing original single-pane casements in a 1920s Marina flat or swapping fogged double-panes in a Sunset District home, this page covers what you need to know before making a decision. We’re part of the Garrison Partners family and stock casement options from eight manufacturer lines, including Mr-Glass, Therma-Tru, and ViewLux. For a free in-home estimate, call (831) 273-7126. You can also learn more about the full scope of our work on our Window Installation in San Francisco page.

When You Need Casement Windows
Casement windows fail in specific, predictable ways. Here’s what we see most often in San Francisco homes:
- The crank mechanism is stripped or jammed. Turn the handle and nothing moves, or the window only opens halfway before grinding to a stop. On pre-1980s casements in the Inner Richmond, we regularly replace worn gearboxes and crank arms that have simply outlived their service life.
- The window won’t seal tight when closed. Casement windows use compression seals, and over time those seals flatten and crack. In the western neighborhoods (Outer Sunset, Outer Richmond), wind-driven rain finds the gaps fast. You’ll feel the draft before you see the leak.
- You’re tired of fighting fogged glass. Double-pane casements with failed seals trap moisture between the panes. No amount of cleaning fixes it. Replacement is the only real solution.
- The hinges sag and the sash drags. Heavy wood and clad casements in older Noe Valley and Glen Park homes develop hinge wear. The window visibly droops at the corner and scrapes the frame when it closes.
- You want windows that actually ventilate the house. San Francisco doesn’t have air conditioning as a standard in most older homes. Casement windows open fully from top to bottom, directing air into the room in a way double-hungs and sliders can’t match.
- You’re replacing windows to cut noise from the street. On busy corridors like 19th Avenue, Geary, or Mission Street, properly sealed casement windows with laminated glass make a real difference. The compression seal is mechanically tighter than a slider’s brush seal.
Our Casement Windows Process
Every casement window installation in San Francisco follows the same sequence. No shortcuts, no surprises at the door.
- Measure and inspect. We come to the house, measure the existing opening, check the rough-frame condition, and look for rot, water damage, or structural issues. In older San Francisco homes, the rough opening is rarely square. We plan for it beforehand, not during.
- Write the price. Before anything is ordered, you get a written quote with the window, frame material, glass package, hardware, and labor broken out. The price goes on paper before any work starts, and it does not move at the door. That’s a Garrison Partners rule, and it applies to every job we do.
- Order the window. We spec the window from one of our eight manufacturer lines. For casements, we often specify from Therma-Tru for wood and clad applications, Mr-Glass for value-driven vinyl work, or ViewLux when a slim profile and maximum glass area matter. The right window for the job, not the one sitting in a warehouse.
- Remove the old window. We cut the exterior sealant, remove the sashes and frame, and inspect the rough opening. If we find rot or water damage, you get a call and a photo before anything goes back in. No hidden work, no surprise change orders.
- Install and seal. The new casement goes in level and square, shimmed properly. We use backer rod and high-grade exterior sealant on the perimeter, and we flash the opening so water drains away from the structure, not into it. In San Francisco’s fog-and-rain climate, flashing is not optional.
- Adjust, test, and walk through. We cycle the crank mechanism repeatedly, check the compression seal around the entire perimeter, and verify the sash opens and closes without binding. Then we walk you through operation and maintenance. If anything fails within 365 days, we come back at no charge under the 365-Day Done Right Promise.
Casement Windows Pricing in San Francisco
Casement window replacement in San Francisco typically costs $900 to $2,400 per window installed. The range reflects real differences in product and site conditions, not negotiation room.
What moves the number:
- Frame material. Vinyl casements land at the lower end of the range. Wood and clad-wood casements from Therma-Tru cost more because of material costs and finishing work. Aluminum-clad casements sit in the middle and hold up well against salt air in neighborhoods near the bay.
- Glass package. Standard double-pane low-E glass (a thin coating that reflects heat while letting light through) is included in most quotes. Laminated glass for noise reduction adds $200 to $450 per window. Tempered glass where code requires it (near doors, low to the floor) adds another $150 to $350.
- Opening condition. If the rough frame is rotted or out of square, repair work adds time and material. We show you photos before proceeding, and the additional cost is written down before the work happens.
- Access and height. Second- and third-story casements on Noe Valley hillsides or Russian Hill flats need ladder or staging work. That’s included in your written quote, not tacked on later.
- Quantity. Replacing three or more casements on the same visit is more efficient per window than doing one at a time. The price per window comes down modestly when the crew is already on site with the right tools and materials.
Here’s a straightforward breakdown of typical per-window installed pricing in San Francisco:
| Casement Window Type | Typical Installed Range (per window) |
|---|---|
| Vinyl casement, basic | $900 – $1,400 |
| Vinyl casement, laminated glass | $1,200 – $1,900 |
| Wood or clad-wood casement | $1,400 – $2,400 |
| Aluminum-clad casement | $1,200 – $2,000 |
Every quote is free. Call (831) 273-7126 and we’ll send a technician to measure and write a price you can hold us to.
What Makes Casement Windows Worth Considering
Casement windows are not the cheapest option. Double-hung and slider windows cost less per unit in most cases. What casements do better is seal out air and water, and that matters in San Francisco’s specific climate.
The compression seal on a closed casement physically presses the sash against the weatherstripping around the full perimeter. A slider uses brush seals that slide past each other. A double-hung relies on interlocking meeting rails. Neither matches the mechanical tightness of a casement’s closed position. That’s why we’ve pulled original casement windows out of 1940s Outer Sunset homes and found the interior casing still solid while the exterior face took decades of direct ocean wind.
Casements also catch wind and channel it into the room. On a typical San Francisco afternoon, when the fog rolls in and the house gets stuffy, an open casement acts like a scoop. That’s a real feature for homes without air conditioning.
A meridian is a fixed line you measure everything against. That’s what the name means and how we run every install. We measure against a clear standard: the written price, the written guarantee, and the workmanship on the sill and casing. If any of it is off, we fix it.
Casement Windows and San Francisco Building Code
San Francisco has specific requirements that affect casement window replacement. Two stand out in our day-to-day work.
First, windows in historic districts (think large portions of the Marina, Pacific Heights, and certain blocks of Noe Valley and Bernal Heights) are subject to the city’s preservation review process. If your building is designated historic or sits in a landmark district, replacement windows typically need to match the original material, profile, and configuration. A vinyl casement may not be approvable. We spec wood or clad-wood casements from Therma-Tru for these jobs, and we coordinate the paperwork before ordering anything.
Second, California’s Title 24 energy code sets mandatory minimums for window U-factor and solar heat gain coefficient. San Francisco sits in climate zone 3, and the code requires windows to meet efficiency thresholds that vary by orientation and glass area. Every casement we install meets or exceeds Title 24. Our written quote includes the compliance documentation with the product specs.
If your home is in a designated historic district, confirm eligibility requirements with the San Francisco Planning Department before replacing windows. We help with that process on every job where it applies.
Signs You Should Replace Rather Than Repair
Some casement problems are fixable. Others aren’t worth the money. Here’s how we tell the difference.
- Broken crank or gearbox: Usually repairable for $150 to $350 per operator if the sash and frame are sound. If the window is 20-plus years old and the glass is original single-pane, replacement often makes more sense than putting new hardware on a worn unit.
- Failed insulated glass: The glass unit can be replaced on some casements, but on older frames with brittle glazing or worn seals, a full window replacement is the honest recommendation. We’ll tell you which one applies to your window and write the price for the right option.
- Roof-level water staining on the interior casing: This is rarely just a window problem. In San Francisco’s older homes, roof flashing and wall drainage fail alongside window flashing. We inspect the full opening and tell you what we actually see. If the problem is the window, we fix the window. If it’s above the window, we tell you to call a roofer before we install a new casement into a leaking opening.
- Frames that are soft to the touch: By the time wood feels soft, the rot extends beyond what you can see. Replacing the casement is the answer, and the work should include repairing the surrounding framing. We do that work as part of the installation, priced and written before we start.
How Long Casement Window Installation Takes
Most single casement window replacements in San Francisco take our crew one full day from start to finish, including removal, rough-opening inspection, installation, sealing, and cleanup. Two to four windows on the same floor usually run two to three days.
Several factors move that timeline:
- Custom window lead time. Casement windows are built to order in most cases. Expect 2 to 6 weeks from the written quote to the installation date, depending on the manufacturer and glass package. We give you a specific availability window when we write the order, and we call before the window ships.
- Historic district review. If the city requires preservation review, add 2 to 8 weeks depending on the current review backlog. We file the paperwork early and follow it through.
- Rot repair. If the rough opening needs structural repair, the job may extend by a day or more. We tell you before the crew arrives, and the schedule reflects it in writing.
- Weather. We install in San Francisco fog and light rain. If heavy rain is forecast, we reschedule at no cost and confirm the new date in writing.
Background-Checked Crews and Clean Job Sites
Who walks through your door matters. Every Meridian Windows and Doors San Francisco technician is background-checked and uniformed. When the crew arrives, you’ll know who they are and why they’re there.
We follow The Garrison Code on every job site. It’s a simple, written set of rules: tarps down before work starts, work areas swept at the end of each day, all trash removed, and the client’s property treated the way we’d treat our own homes. The Code also covers the no-surprises rule: if an issue comes up mid-install, we stop, show you what we found, and put the fix on paper before doing the work.
You’ll also never reach a voicemail loop when you call. Phones are answered by a live person 24 hours a day, every day of the year. After the install, if something isn’t right, you call, a person answers, and we schedule the return visit. That’s covered by the 365-Day Done Right Promise, in writing, on every job.
Casement Windows and Sound Reduction
San Francisco’s noise is specific. Muni buses on Geary. The J-Church running outside your bedroom window. Garbage trucks at 6 a.m. on a steep hill in Potrero. Fog horns. Bart trains rumbling through the Mission.
Casement windows help because of the compression seal. The mechanical pressing of the sash against the weatherstripping reduces air leakage, and air leakage is how sound travels through a closed window. Add laminated glass, and the reduction is more noticeable. Laminated glass uses a plastic interlayer between two panes that disrupts sound transmission.
We’ve installed laminated casements in Outer Richmond apartments facing the corridor off 19th Avenue where traffic noise is constant. Homeowners report the difference in days, not weeks. You’ll pay more for laminated glass, and we’ll tell you honestly if it’s worth it for your situation. On a quiet Noe Valley side street, standard double-pane casements do plenty.
Casement Windows vs. Awning Windows
People ask about this because the two styles look similar in catalogs. The difference is the hinge location.
- Casement windows hinge at the side and swing left or right. They work well on tall, narrow openings and next to fixed picture windows.
- Awning windows hinge at the top and push outward from the bottom. They’re smaller in typical residential use and often installed in pairs or rows for ventilation.
In San Francisco, casements are the more common replacement for original wood windows in pre-war homes. Awning windows show up more often in kitchens, bathrooms, and above Picture & Fixed Windows. Both are available from our manufacturer lines. We’ll spec whichever fits your opening and your priorities.
Frequently Asked Questions About Casement Windows in San Francisco
How much does casement window replacement cost in San Francisco?
Casement window replacement in San Francisco typically costs $900 to $2,400 per window installed, with vinyl casements at the lower end and wood or clad-wood casements at the higher end. The final number depends on the frame material, glass package, opening condition, and access. Call (831) 273-7126 for a free, written quote specific to your home.
Are casement windows better than double-hung windows?
Casement windows seal tighter than double-hung windows because their compression seal presses the sash firmly against the weatherstripping when closed, which reduces air leakage and improves energy efficiency. Double-hung windows offer easier cleaning and a more traditional look. For San Francisco homes where wind and fog are factors, casements or Horizontal Roller Windows often make more sense. We’ll show you both options and the honest trade-offs before you decide.
Can you install casement windows in a historic San Francisco home?
Yes, but historic district homes usually require window replacements that match the original material, profile, and configuration, so vinyl casements may not be approvable. We spec wood or clad-wood casements from Therma-Tru for historic district work and manage the preservation review paperwork with the San Francisco Planning Department. Call (831) 273-7126 and we’ll check your property’s status before you spend anything.
How long does it take to replace a casement window?
Most single casement window replacements take one full day once the window is on site, but custom casement windows typically have a 2 to 6 week lead time from order to installation. Historic district review can add 2 to 8 weeks if it applies. We give you a firm timeline in writing when you approve the quote, and we call before the window ships.
Do you offer a warranty on casement window installation?
Yes. Every casement window installation is covered by our written 365-Day Done Right Promise. If the work fails within 365 days of installation, we return and fix it at no charge. That includes labor, not just the window product. The guarantee is written into every contract, and it’s backed by Meridian Windows and Doors San Francisco as part of the Garrison Partners family.
