Fast, Reliable Window Replacement Across Pasadena
Window replacement in Pasadena is rarely a simple swap. Between the landmark districts, the 100°F summer afternoons, and hundred-year-old framing that has settled in ways no tract home ever will, a window job here takes a crew that knows exactly what it is looking at. TruePane Windows & Doors has been doing that work in Pasadena since the day Dale Kessler founded the company in 2008, and we approach every bungalow, Spanish Colonial, and Mediterranean Revival home with the same rule: if the pane is not true, the job is not done. Call (888) 635-0804 and a live person answers, day or night.
Why TruePane Windows & Doors Is Pasadena’s Preferred Window Replacement Company
We are not the cheapest bid you will get in Pasadena, and we will tell you that before you ask. What we offer is a square deal and a crew that measures every opening twice, quotes manufacturer lines side by side on paper, and registers both warranty layers before the truck leaves the driveway. That is The Keystone Standard, and it applies to every job from a single fogged sash in Bungalow Heaven to a full-house replacement in San Rafael.
Our technicians are background-checked and uniformed, and they work in your home the way they would work in their own mother’s. The response time to Pasadena from our Los Angeles office is same-day for estimates in most of 91101 and the surrounding neighborhoods. We know that the Craftsman double-hung in your dining room was probably installed when the house was built, and we know the Design Review process that governs what can go back in its place. That local knowledge is not something you can learn from a franchise playbook.
We have spent years in this trade, and we hire local, train apprentices into journeymen, and sponsor county fairs and church roof funds because we plan to be here in thirty years. When a Pasadena homeowner calls us back five years after an install because a seal failed, the phone still rings at our shop, and a real person still picks up the line. We stand behind the work, in writing.
Our Window Replacement Services in Pasadena
Full Frame Replacement
A full frame replacement means pulling the entire existing window out down to the rough opening, repairing or replacing any rotted framing, and setting a new window with new flashing. In Pasadena this is the standard for original 1900s wood sash windows that have dry-rotted sills, and it is the only option when Historic Preservation requires a specific sash profile that cannot be retrofitted into an old frame. Expect a full frame job in Pasadena to run roughly $1,100 to $2,800 per window depending on size, framing condition, and whether the unit is a custom wood or clad-wood match for a designated landmark property.

Insert Window Replacement
An insert, sometimes called a pocket replacement, fits a new window inside the existing frame without disturbing interior trim or exterior stucco. It works well on mid-century Pasadena homes and on rear elevations where the original frame is square and sound. Inserts are less invasive and faster to install, typically running $650 to $1,500 per window in Pasadena for a quality vinyl or wood unit with low-E glass. But we will tell you straight: if the frame has rot or the sash dimensions are non-standard, an insert is the wrong call and we will not sell you one.

Storm Window Replacement
Some Pasadena homeowners want to keep their original wood windows intact for historic reasons and add a modern exterior storm window for energy performance and noise reduction. This is a legitimate strategy in landmark districts where the original sash cannot be altered, and Pasadena’s Historic Preservation staff generally reviews storm windows more favorably than full vinyl replacements. Expect to pay $380 to $700 per exterior storm unit in Pasadena, installed, with low-E glass as an option.

Energy-Efficient Upgrade
Pasadena sits at the foot of the San Gabriel Mountains and regularly tops 100°F in July and August. East and west facing windows without modern low-E coatings turn those rooms into ovens by mid-afternoon, and your air conditioner pays the price. A standard energy upgrade in Pasadena runs $700 to $1,700 per window for a dual-pane unit with low-E and argon fill, but the specific glazing package matters more than the brand. We calculate solar heat gain by orientation, not by guesswork, and we will write the specs on your quote.

Historic Window Restoration
This is the Pasadena specialty. When a 1922 Craftsman bungalow still has its original single-pane wood double-hungs, the right answer is often restoration, not replacement. We rebuild sash, replace broken glass, re-putty and re-weight, and add weatherstripping. Where replacement is required in a Landmark District, we order true divided-light wood or aluminum-clad wood units whose sash profiles match the original on file with the city. Historic restoration in Pasadena runs $900 to $2,200 per window depending on the condition of the sash and the degree of custom matching required. We will always show you the restoration option alongside the replacement option, on paper, with prices.

Trusted Brands We Service in Pasadena
TruePane is an authorized installer for more than a dozen manufacturer lines, including, plus impact-rated product from PGT and CGI for foothill homes in the fire hazard zones. On a Pasadena bungalow we frequently quote Marvin wood double-hungs side by side with PGT impact vinyl so the homeowner sees exactly what each specification costs. We stock common service parts for Pasadena’s dominant window styles, which means a broken balance or latched sash on an older Andersen or Milgard unit does not have to wait for a regional distribution order. Most jobs in Pasadena are completed in a single visit, and both warranty layers are registered in writing before we leave the driveway.
Common Window Replacement Problems We See in Pasadena Homes
- Dry rot in original wood sills and frames. A century of sprinkler overspray and occasional winter rain has worked its way into countless Pasadena window frames. By the time a homeowner notices the paint bubbling, the rot often extends into the rough opening and requires full frame repair before a new unit can be set.
- Fogged double-hung sashes from failed seals. The wide temperature swings between Pasadena’s cold winter mornings and 100°F summer afternoons stress the seal on dual-pane glass. When the seal fails, moisture gets in and the glass fogs. The fix is replacement of the insulated glass unit, not the whole window, and we can usually do that in one visit.
- Vinyl replacements rejected by Design Review. We have lost count of how many Pasadena homeowners bought an estimate from an out-of-town company, ordered standard vinyl double-hungs with simulated divided lights, and then had the permit denied because their house sits in Bungalow Heaven or another Historic Landmark District. The city requires true divided-light wood or clad-wood units matched to the original sash profile. That mistake adds weeks and can double the cost.
- Solar heat gain on west-facing rooms. A 1940s Spanish Colonial on Orange Grove with original single-pane windows will see afternoon interior temperatures twenty degrees hotter than a properly glazed house down the street. Title 24 compliance aside, the comfort difference on a Pasadena afternoon is something you can feel immediately.
Pricing for Window Replacement in Pasadena, CA
The honest range for Pasadena is wider than most homeowners expect, and the Historic Landmark overlay is the biggest driver of that spread. A standard vinyl insert on a mid-century ranch might run $650 per window, while a true divided-light Marvin wood double-hung on a landmark bungalow can hit $2,800 per window once Design Review matching, full frame repair, and Title 24 glazing are factored in. The median Pasadena job, blending insert and full frame work plus a few energy upgrades, lands between $900 and $1,900 per window. We give free written estimates with line items, and the price we quote is the price you pay. No change orders for access problems we should have spotted, no surprise line items on the bill, no arguing. If it is not done right, we make it right under the Done Right Promise. Call (888) 635-0804 to schedule your free estimate.
Working on a Tight Pasadena Lot Is Part of the Job
On a 1922 Craftsman bungalow in Bungalow Heaven, our crew removed original single-pane double-hung wood sashes with failed glazing and installed custom Marvin wood double-hungs with true divided lights, low-E glass, and argon fill to meet both Historic Preservation and Title 24. Staging on a 30-foot lot forced us to stack materials in the driveway and schedule deliveries one window at a time, while we posted party-wall notices and kept noise within Pasadena’s 7 a.m. to 6 p.m. construction hours. That is what the job actually looks like in Pasadena’s historic core: no crane, no street closure, just careful scheduling and a clean work area the neighbors can tolerate.
On a tight Pasadena lot, access changes the quote. A second-story window on a house with a narrow side yard and a shared wall cannot be reached from the outside with a ladder truck or boom lift. We stage inside, through the house, which means protecting floors, moving furniture carefully, and keeping dust contained. If your neighbor shares a wall, we post notification at least 48 hours before work begins and we keep the noisy work inside Pasadena’s permitted hours. A clean job site on a narrow lot is the difference between a one-day install and a standoff with the neighbor across the driveway. We have done the one-day version many times.
Contractors who have worked Bungalow Heaven know that submitting a vinyl window with simulated divided lights for a Design Review permit is an automatic rejection. Pasadena’s Historic Preservation staff requires true divided-light wood or aluminum-clad wood units whose sash dimensions match the original Craftsman profile on file, a specification that can add weeks to project timelines and double the window cost compared to a straightforward swap in Arcadia or Monrovia. We know the paperwork before the first measurement is taken, and we build that into the estimate so there are no surprises at permit review.

FAQs - Window Replacement in Pasadena
No, and this is the most common mistake we see from homeowners who have already signed with an out-of-town installer. If your house is in a designated Historic Landmark District such as Bungalow Heaven, Pasadena’s Historic Preservation staff will reject standard vinyl units with simulated divided lights. The city requires true divided-light wood or aluminum-clad wood windows with sash dimensions that match the original Craftsman profile on file. On a non-landmark Craftsman or a home outside the district boundary, vinyl may be acceptable, but you should verify the designation before ordering anything. Call (888) 635-0804 and we will check your address against the city’s landmark maps before we quote a single window.
Yes, Pasadena requires building permits for window replacement when the work changes the size of the opening or when the property is in a Historic Landmark District. Like-for-like replacement of the same size window in a non-landmark home may be exempt, but a 1920s Craftsman is far more likely to be in a district than not. Pulling the permit ourselves, submitting the Design Review application, and attending the review if needed is part of our standard service. We do not ask the homeowner to handle city paperwork. Call (888) 635-0804 and we will walk you through exactly what your property requires.
Homes in the northern Pasadena foothills fall within California’s designated Very High Fire Hazard Severity Zone, which means replacement windows and exterior doors must meet specific fire-rating and glazing requirements. Tempered glass or fire-rated glazing is generally required in certain locations, and framing materials may need to be non-combustible or fire-resistant. Skipping these requirements can void both your permit and your insurance coverage. We quote impact-rated PGT and CGI product lines alongside standard glass for foothill properties so you can see the cost difference in writing. Call (888) 635-0804 for an exact quote on your street.
Yes, and tight shared-wall lots are routine for us in Pasadena’s historic neighborhoods. We post party-wall notice at least 48 hours before work starts, keep all construction noise inside Pasadena’s 7 a.m. to 6 p.m. ordinance hours, and stage materials on your property, not in the shared driveway unless you and your neighbor agree. On second-story windows where exterior staging is not workable, we stage through the interior using drop cloths and dust barriers. A narrow 30-foot lot adds time and care, not a confrontation. Call (888) 635-0804 and we will walk the site before the quote.
The seal on the insulated glass unit failed. Moisture got in, and now the argon or air fill is contaminated and the window fogs any time the temperature changes, which in Pasadena is most days. Wide temperature swings between cool foothill mornings and 100°F afternoons stress seals, especially on units that have been in place for fifteen years or more. The repair is a replacement of the insulated glass unit itself, not the entire window frame, which in Pasadena typically runs $280 to $600 per sash depending on size and glass specification. Call (888) 635-0804 and we can usually replace a failed IGU in one visit.
