AfterSingle & Double Hung Windows in Pasadena, CA
Single hung and double hung windows remain the most common window style in Pasadena homes, from the Craftsman bungalows of Bungalow Heaven to the mid-century ranches in Hastings Ranch, though some homeowners also consider options like Awning & Hopper Windows for specific needs. Single hung windows open from the bottom sash only, while double hung windows let both the top and bottom sashes slide up and down, which improves airflow and makes cleaning easier. Most replacement projects in Pasadena run between $650 and $1,300 per opening depending on size, frame material, glass package, and whether the existing frame needs repair. If you’re weighing options for your home, call Lightwell Windows Pasadena at (626) 628-2308 for a free estimate with a written price before any work starts.
A light well is what brings daylight deep into a building. That is what a well-installed window should do for your home, and it’s the standard we work to on every hung window job in Pasadena. We’re part of the Cedarwell network and have operated to the Cedarwell Care Promise since 2010, carrying eight manufacturer brands so the recommendation fits your house, not a preferred vendor. For a fuller look at what goes into any window project, see our Window Installation page.
Key takeaways for Pasadena homeowners:
- Single hung windows cost less upfront; double hung windows are easier to clean and ventilate better.
- Most hung window replacements in Pasadena run $650 to $1,300 per opening installed.
- Our written price comes before any work starts, with no invoice surprise at the end.
- Every job is covered by the 365-Day Done Right Promise: if it’s not right, we make it right.
- Crews wear shoe covers, lay drop cloths, and photograph the clean-up before leaving.
When You Need Single & Double Hung Windows
Pasadena’s older housing stock means a lot of hung windows have been in place for 40, 60, or 80 years. Here are the signs we see most often in homes across the city:
- Sashes that stick or won’t stay open. Old wooden frames swell with Pasadena’s winter rains and shrink in the dry summer heat. If you have to prop a window open with a book, the sash, balances, or frame are failing.
- Visible daylight through closed sashes. Gaps around the sash let conditioned air escape. In Altadena and the foothills, where afternoon heat builds hard in August, a leaky hung window raises cooling costs measurably.
- Drafts you can feel standing two feet away. Single-pane hung windows from the 1950s and earlier have almost no insulating value. Replacing them with double-pane glass changes the temperature feel of a room within a day.
- Fogged glass or failed seals. When condensation sits between the panes, the insulated glass unit has failed. A hung window with fogged glass can’t be cleaned clear, so the opening needs a new sash or a full replacement.
- Lead paint concerns on pre-1978 homes. Many Pasadena homes predate the lead paint ban. Aged double hung windows are one of the most common places families encounter lead dust, especially with friction surfaces like sashes and tracks.
- Noise from the street or the 210. Homes near the freeway, Colorado Boulevard, or busy school drop-off zones often need hung windows with a stronger acoustic glass package. We can match the glass to the specific noise problem.
If any of those sound familiar, we’re happy to look at the windows and tell you honestly whether repair or replacement makes more sense. That conversation costs you nothing. Call (626) 628-2308 and we’ll set a time.
How Much Do Single & Double Hung Windows Cost in Pasadena?
Most hung window replacements in Pasadena run between $650 and $1,300 per opening installed. That’s the range we quote most often for standard sizes in wood, vinyl, or fiberglass frames with double-pane glass. Here’s how the pricing tends to break down:
| Window Type | Frame Material | Typical Installed Range (Per Opening) |
|---|---|---|
| Single Hung | Vinyl | $650 – $950 |
| Single Hung | Wood or Composite | $850 – $1,200 |
| Double Hung | Vinyl | $750 – $1,100 |
| Double Hung | Wood or Composite | $900 – $1,300 |
| Double Hung, Custom Size | Any | $1,100 – $1,800+ |
What moves the number:
- Size and shape. A standard 36″ x 60″ double hung costs less than a 48″ x 72″ or a custom width made for an older Craftsman opening. Pasadena’s pre-1940 homes often have non-standard rough openings that require custom-sized sashes.
- Frame material. Vinyl is the most budget-friendly. Wood and composite frames cost more but preserve the look of original hung windows in historic districts, which matters if you’re in a neighborhood with design review.
- Glass package. Standard double-pane Low-E argon glass is the baseline. Upgrading to acoustic glass, triple-pane, or a stronger solar control package for west-facing rooms adds $150 to $400 per opening.
- Installation complexity. If the existing frame is rotted from years of sprinkler overspray or missing flashing, we’ll need to rebuild the rough opening. That adds labor and materials, and we’ll tell you before starting, not after.
We carry eight brands, including PGT, CGI, CWS, and ViewLux, so the price you pay reflects the right window for your home rather than whatever single product line an installer happens to sell. Every quote includes a written price before any work starts. That is a standing rule at Lightwell, not a courtesy.
Our Single & Double Hung Windows Process
We’ve refined our process over the years to be methodical, quiet, and clean. Here’s what a hung window replacement looks like with us:
- Walkthrough and measurements. We start at your home. We measure each opening, check the existing frame and weight pockets, and listen to what’s bothering you about the current windows. We’ll explain which brands we carry, including ViewLux and PGT, and why one might fit your home better than another.
- Written quote, before anything is ordered. You get a line-item price on paper. No estimate ranges you have to decode, no “we’ll see how it goes.” Every dollar is on the page before we touch a window.
- Order and schedule. We place the order with the manufacturer and confirm an install date. If you have kids or pets, we’ll schedule the noisiest work outside nap time where possible, and we always respect quiet hours. Our C.A.R.E. values guide this: we Respect the family’s time and Ask before we move or touch anything.
- Installation day. The crew arrives in uniform, background-checked, and we lay drop cloths and wear shoe covers from the moment we walk in. We protect floors, furniture, and pet areas with drop cloths before the first tool comes out. We use pet-safe caulk and sealants wherever there’s a choice.
- Clean up and photograph. Before the crew leaves, we take a photo of the clean-up and the finished windows. You’ll see what we see. The C in our C.A.R.E. values stands for Clean up like it’s our own home, and that’s not a slogan. It’s what the crew does because Keith has built the company that way.
- 365-Day Done Right Promise. Every hung window we install is covered. If something isn’t right within the first year, Lightwell makes it right. No debate, no countdown, no fine print.
Single Hung vs. Double Hung: Which Should You Choose?
Most Pasadena homes we work in have traditionally had double hung windows, especially the Craftsman and Victorian styles, though 3-Panel Sliding (3-Lite Roller) Windows can work well for certain openings. But the right choice depends on the room, the budget, and what you want the windows to do.
Single Hung Windows
Single hung windows open from the bottom sash only. The top sash is fixed. They cost less than double hung, have fewer moving parts, and are easier to seal tightly. For upper-floor windows that rarely get opened, single hung is often the smarter spend. PGT and CWS both make solid single hung lines that perform well in Pasadena’s climate.
Double Hung Windows
Double hung windows let both sashes slide. You can open the top, the bottom, or both, which creates natural convection: warm air exits through the top, cooler air enters through the bottom. On Pasadena evenings when the marine layer cools things off fast, that airflow makes a real difference in bedrooms and living rooms. Double hung windows are also easier to clean from inside, which matters on second-story openings where leaning out with a ladder is not safe.
For families with young kids, double hung windows with tilt-in sashes and secure locks offer better ventilation control. You can open the top sash for airflow while keeping the bottom sash closed and locked, so a toddler can’t climb against an open opening.
If you’re still deciding, we’ll show you samples and give you our honest recommendation based on the room and how you live. Call (626) 628-2308 and we’ll talk through it.
Pasadena-Specific Window Considerations
Pasadena homes come with a few window realities that matter for hung windows specifically.
Historic District Requirements
If your home is in a designated historic district, such as Bungalow Heaven or the Civic Center area, any window replacement may require design review. Original wood double hung windows are often a contributing feature, and the city may require replacement windows to match the original profile, muntin pattern, and material. We’ve worked with Pasadena homeowners to navigate these requirements, and we can recommend hung window options that satisfy review boards while giving you modern glass performance. We never shortcut this process.
Heat and Sun Exposure
Pasadena gets real heat. Summer afternoons regularly reach the high 90s, and west-facing hung windows take the brunt of it. For those openings, we often recommend a stronger solar control Low-E coating or a slightly tinted glass package from CGI or ViewLux. The right glass changes the feel of a room without changing the look of the window from the street.
Older Frame Conditions
Homes built before 1950 in neighborhoods like Madison Heights, Garfield Heights, and Oak Knoll often have hung windows set in wood frames that have been painted over for decades. We inspect for rot around the sill and jamb corners, especially on south-facing walls where sprinklers soak the sill every morning. If the frame needs repair or replacement, we’ll show you photos and include the work in your written quote before we ever order the window.
Window Weight Pockets
Older double hung windows use cast-iron weights and ropes inside the wall cavity. When we replace those windows, we insulate the weight pockets. That’s a step some installers skip, and it’s a big part of why a new window can still feel drafty if it’s not done. We fill and seal those cavities so the whole opening, not just the visible frame, contributes to the home’s comfort.
Our approach to every opening is the same: treat the house like a home, not a job site. That is the Cedarwell Care Promise in practice, and we’ve been working to it since 2010.
Why Pasadena Homeowners Choose Lightwell Windows & Doors
We’re not the biggest window company in Pasadena, and we don’t try to be. We’re an independently owned and operated Cedarwell location, which means we carry contractor-grade product selection with the accountability of a neighbor who answers the phone. Here’s what that looks like in daily practice:
- Eight manufacturer brands on hand. PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. We’ll help you choose based on your home, your budget, and your priorities, not our preferred vendor.
- 365-Day Done Right Promise. If the finished work is not right, we make it right. It’s stamped on every job, including the small ones. Most window problems that show up appear within the first year, and that’s exactly the window of time we cover without debate.
- Written price before any work starts. Not a verbal estimate. Not a range. A written, line-item price. If something changes during the job, we tell you before we do the work and get your OK in writing.
- Background-checked, uniformed technicians. You know who’s at your door before they knock. Our crew wears uniforms, carries identification, and follows the C.A.R.E. values on every visit: Clean up like it’s our own home, Ask before we move or touch anything, Respect the family’s time and quiet hours, and Explain the price before the work.
- A live person answers the phone, 24/7. If something goes wrong with a new install at 9 p.m., you call and a human picks up. No voicemail maze, no “we’ll get back to you within two business days.”
We work with homeowners who’ve been burned before by crews that left dust on the floors or handed them a bigger number at the end than the one they agreed to at the start. If that’s you, we understand the hesitation. You’ll get the written price, the drop cloths, the shoe covers, and the photo of the clean-up before we leave, on every single visit.
FAQs – Single & Double Hung Windows
How much does it cost to replace single or double hung windows in Pasadena?
Replacing a single or double hung window in Pasadena typically costs between $650 and $1,300 per opening installed, depending on size, frame material, glass package, and whether the existing frame needs repair. Custom sizes for older homes can run higher, from $1,100 to $1,800 or more. Call (626) 628-2308 for a free, written quote specific to your home.
Is it cheaper to repair or replace a hung window?
Repairing a hung window, such as replacing a broken sash cord or balance, usually costs $150 to $400 per window if the frame and glass are still in good shape. Replacement makes more sense when the frame is rotted, the glass is fogged, or the window is single-pane and drafty. We’ll give you an honest recommendation after looking at the actual condition of your windows, and your estimate is free.
Can you install double hung windows the same day?
Installation of standard-sized double hung windows typically takes one day for several openings, once the windows have been manufactured and delivered. Custom sizes add lead time, usually two to four weeks depending on the brand. If you need a specific timeline, call (626) 628-2308 and we’ll give you a realistic schedule.
Do double hung windows improve energy efficiency in Pasadena homes?
Yes. Replacing single-pane hung windows with double-pane, Low-E coated hung windows reduces heat gain in summer and heat loss on cooler winter nights, which is the pattern Pasadena experiences year-round. Sealing the weight pockets in older walls also eliminates a draft path that many homeowners never see. The difference is most noticeable in west-facing rooms and second-story bedrooms.
Are your window installers background-checked and trained?
Yes. Every Lightwell technician is background-checked, uniformed, and trained on the Cedarwell Care Promise. Our crews wear shoe covers, lay drop cloths, use pet-safe products where a choice exists, and photograph the clean-up before they leave. The C.A.R.E. values are in place on every visit: Clean up, Ask before moving anything, Respect the family’s time, and Explain the price before the work.
Do you offer a warranty on single and double hung window installation?
Every window we install is covered by the 365-Day Done Right Promise. If the finished work is not right within that first year, Lightwell makes it right. Manufacturer warranties on the window products themselves vary by brand, and we’ll explain the specific coverage for the window you choose before you decide. Call (626) 628-2308 for details on any brand we carry.
