Single & Double Hung Windows in San Jose, CA
Single hung and double hung windows are the most common window styles in San Jose homes, and for good reason. A single hung window has a fixed top sash and a bottom sash that slides up to open. A double hung window lets both sashes move, so you can open the top, the bottom, or both at once. At Westlight Windows San Jose, our Window Installation team covers both styles across the city, and most full-frame replacements in San Jose run between $700 and $1,600 per window installed, depending on size, glass package, and whether you choose vinyl, wood, or composite frames.
If you’re replacing old aluminum windows in a Willow Glen bungalow or swapping out fogged double panes in an Evergreen two-story, you’ll want a window that opens smoothly, seals tightly, and holds up to San Jose’s dry summers and rainy winters. That’s the kind of work we’ve done since 2009. Call us at (669) 333-7786 and we’ll give you a written price before any work starts. If you’re still deciding between styles, our Window Installation in San Jose page walks through the full range of options we carry.
We’re an independently owned and operated Kingswell location, and Owen Satterfield leads our San Jose team. The name Westlight comes from the late-afternoon sun that pours through a good window. Bright, warm, and worth doing right. That’s the standard we install to.
When You Need Single & Double Hung Windows
Most San Jose homeowners call us when their windows have stopped doing the job they were built for. Here are the situations we see most often across the city:
- Fogged or cloudy glass. If you can’t see through the pane anymore, the seal has failed. In San Jose’s temperature swings, we see this constantly in windows that are 15 years old or older. Replacement is the fix, not a repair.
- Sashes that won’t stay open. A window that slams shut on its own has failed balance springs. On an old single hung in a Rose Garden home, the spring wears out and the sash becomes a guillotine. That’s a safety issue, especially with kids in the house.
- Drafts you can feel from across the room. In Almaden Valley homes built in the 1970s and 1980s, the original aluminum frames conduct heat and cold straight through the wall cavity. You’re paying to heat or cool the outside.
- Rot or swelling around the frame. Wood sashes in older San Jose neighborhoods like Naglee Park absorb winter moisture and swell, then shrink in summer. Once the frame stops sealing, it’s time for a full replacement.
- Windows painted or caulked shut. We see this all the time in rental conversions and older West San Jose homes. A window you can’t open is a fire escape you don’t have.
- Noise from the street. If you live near Bascom Avenue, The Alameda, or a school zone, a quality double hung with laminated glass can cut outside noise dramatically.
Our Single & Double Hung Windows Process
We don’t do surprises. Here’s exactly how a window replacement goes with us, from the first call to the final walkthrough:
- You call and talk to a real person. Our lines are answered live 24 hours a day, 7 days a week. Not a voicemail box, not a chatbot. You’ll schedule a time that works for you, and we’ll give you a committed arrival window.
- We measure and assess your existing windows. One of our background-checked, uniformed technicians comes to your home, checks the condition of the frames and sashes, and measures every opening. We’ll talk through your goals: energy savings, noise reduction, ease of use, or all three.
- You get a written price before any work starts. This is the Kingswell Way: say the price before the work. We write it down, item by item, and hand it to you. No revised invoices at the door. No “we found something” line. The price we hand you is the price you pay.
- We order your windows from the right manufacturer. We carry eight lines, so the window gets matched to the job. For a hot west-facing bedroom in Cambrian, we might spec an ECO Window Systems low-e package. For a Craftsman in Shasta Hanchett, we’d look at a wood-look composite from Mr-Glass or ViewLux. The job dictates the product, never the other way around.
- Installation day. Our crew shows up in the window we gave you. We protect the work area, remove the old sashes, set the new frames square and level, insulate the gap, and trim out the exterior. When we leave, the site is cleaner than we found it.
- You get a written guarantee before we walk out the door. Every job includes the 365-Day Done Right Promise. If the work isn’t right within the guarantee period, we come back and fix it at no charge. And if a repair fails down the line, our Free Second Visit applies automatically. No negotiating, no fine print.
Single & Double Hung Windows Pricing in San Jose
Here’s the straight answer on cost. For a standard-sized vinyl single hung window in San Jose, full replacement runs approximately $700 to $1,200 installed. A double hung with the same footprint typically runs $800 to $1,400 installed. Larger openings, wood or composite frames, impact glass, and specialty glass packages push the upper end to $1,600 or more per window.
What actually drives the price:
- Window size and opening count. A bigger sash uses more glass and more frame material. Bedrooms and living rooms cost more than bathroom windows.
- Frame material. Vinyl is the most affordable. Composite and wood cost more but deliver a different look, which matters in historic districts like Naglee Park or Shasta Hanchett.
- Glass package. Low-e glass (a thin coating that reflects heat back into the room in winter and out in summer) is standard on most replacements, but dual-pane argon, triple-pane, or laminated glass for noise control adds cost that pays back in comfort.
- Condition of the existing opening. If the old frame has rot or termite damage, the repair work adds to the total. We’ll tell you before we start, in writing, because that’s the point of our upfront pricing.
- Access. Second-story windows or tight side-yard access changes the labor cost. We’ll walk the property at the estimate so there are no discoveries later.
We don’t give vague ballparks over the phone and then “re-evaluate” at your door. We give you a written price before any work begins, and that’s the price you’ll see on the invoice.

Single Hung vs. Double Hung: Which One Is Right for You?
Both styles look nearly identical from the street. The difference is how they operate and what you get for your money.
A single hung window has one moving sash at the bottom. The top sash stays fixed. It’s the more affordable option and works well in most rooms where you only need ventilation from the lower portion. In San Jose’s mild climate, we recommend single hungs for bedrooms, hallways, and other spaces where top-down ventilation isn’t a priority.
A double hung window lets both the top and bottom sashes slide. That means you can open the top sash on warm nights and let hot air escape, while the bottom stays closed for safety. For homes with kids or pets, that’s a real advantage. Double hungs also tilt inward for cleaning, so you can wipe both sashes from inside the house. If you have a two-story home in Berryessa or Almaden, you know how much that matters when the upstairs windows get dusty.
Cost-wise, a double hung runs about $100 to $200 more per window than a comparable single hung. Over the life of the window, most San Jose homeowners we talk to find the added flexibility worth it, especially for rooms that get afternoon sun or need cross-ventilation.
What We Install and Why It Matters
We carry eight manufacturer lines including options for 3-Panel Sliding (3-Lite Roller) Windows, and that matters because no single brand is right for every house. When we spec windows for a San Jose home, we’re looking at sun exposure, street noise, age of the structure, and what the homeowner actually wants the window to do.
For a mid-century ranch in Willow Glen with big west-facing picture windows, we’d likely recommend a ViewLux or Mr-Glass product with strong low-e ratings to cut afternoon heat gain. For a home near a busy road in West San Jose, we might spec PGT glass with laminated panes to knock down traffic noise. Therma-Tru is best known for entry doors, but their window lines hold up well in San Jose’s dry summers, which can warp cheaper wood frames.
We match the product to the job. That’s the whole point of carrying eight lines instead of pushing one brand with a higher margin. Owen Satterfield built the San Jose branch on that principle, and we’ve stuck to it since 2009.
One thing we won’t do is sell you a window that’s wrong for your house just because it’s easier for us to install. San Jose homes range from 1920s Craftsman bungalows to 1990s stucco tract houses, and each one needs a different set of glass and frame specs.
San Jose Building Codes and Your Window Replacement
When we replace windows in San Jose, the work has to meet California’s Title 24 energy standards and the city’s local building code. That means specific U-factor and Solar Heat Gain Coefficient (SHGC) ratings, which vary depending on which climate zone your home sits in. Most of San Jose is in climate zone 3 or 4, where the state prioritizes windows that block solar heat while still letting in daylight.
We pull the permits, we schedule the inspections, and we match the glass specs to what the code requires. You don’t need to figure out SHGC ratings. That’s our job. But it’s worth knowing that a cheap window from a big-box store often won’t pass a Title 24 inspection in San Jose, which means the “savings” evaporates when the project gets flagged.
Egress is another factor. Any window in a bedroom must meet minimum opening dimensions for fire escape. In many older San Jose homes, the original bedroom windows are undersized by today’s code. When we replace them, we’ll bring the opening up to current egress standards so your home is actually safer after the job, not just prettier.
Why San Jose Homeowners Choose Westlight Windows San Jose

- The Kingswell Guarantee. A written price before any work starts. A committed arrival window. A clean job site. A written guarantee on the completed work. All four promises, on every project, no exceptions.

- Free Second Visit if a repair fails. This one’s automatic. You don’t ask for it. It’s already yours.
- Live phone coverage 24/7. Call at 2 a.m. on a Sunday, a real person answers. Not a voicemail box. Not an answering service that takes a message and promises a callback. A human being who can schedule, answer questions, or dispatch help.
- Background-checked, uniformed technicians. You’ll know exactly who’s walking through your door, and they’ll show up in the window we gave you.
We’ve been doing this since 2009, and we’ve kept the same standard that whole time. Say the price before the work. Show up when we said we would. Leave the place cleaner than we found it. Put the guarantee in writing. Come back if it fails. That’s the Kingswell Way, and it’s the only way Owen runs this shop.
FAQs – Single & Double Hung Windows
How much does it cost to replace a single hung window in San Jose?
A standard single hung window replacement in San Jose typically costs between $700 and $1,200 installed, depending on size, frame material, and glass package. Double hungs run $800 to $1,400 for the same footprint. You’ll get a written price before any work starts when you call (669) 333-7786, and that price won’t change at the door.
Is it cheaper to repair or replace a double hung window?
If the problem is a failed balance spring, a broken sash lock, or worn weatherstripping, a repair is usually cheaper than a full replacement. But if the glass seal has failed, the frame has rot, or the window is more than 20 years old, replacement is the smarter long-term investment. In San Jose’s climate, fogged glass never fixes itself, and we’ll tell you honestly which route makes sense for your window. Call (669) 333-7786 for a straight answer at no cost.
Can you install double hung windows the same day?
In most cases, no, because the windows we install are built to your exact measurements. Standard windows take one to three weeks from order to installation. If a window is in stock and your opening is a standard size, we can sometimes install sooner. We’ll give you a committed install date when you get your written estimate, and we show up on that date.
Do double hung windows help with San Jose summer heat?
Yes. A double hung window with low-e glass and the right SHGC rating blocks a significant portion of solar heat before it enters your home. The top sash also lets you vent hot air out on summer evenings, which helps cool the house without running the AC as hard. For west-facing rooms in San Jose, the right glass package can make a noticeable difference in afternoon comfort.
Will you match my existing window style?
In most San Jose neighborhoods, we can match the existing look closely enough that neighbors won’t notice the swap. For historic homes in Naglee Park or Shasta Hanchett, we’ll work with you on a style that fits the architecture, including Awning & Hopper Windows where appropriate. We’re not going to put a white vinyl retrofit window in a 1920s Craftsman. That’s a line Owen won’t cross.
