Why TruePane Windows & Doors Is Altadena’s Preferred Door Installation Company

We’ve pulled permits through LA County Building & Safety enough times to know exactly what the plan checker will flag on a door submittal. That matters here, because Altadena is unincorporated. A contractor who mostly works Pasadena or La Cañada often shows up with the wrong forms or misses the Chapter 7A fire-glazing callout, and the plan check bounces. We don’t make that mistake. We submit the county application the first time, with the fire-rating detail already noted on the plans.

Dale Kessler founded TruePane in 2008 with one rule written on the shop whiteboard: if the pane is not true, the job is not done. That rule extends to every door we hang. The jamb has to be square, the slab has to clear the threshold without dragging, and the weatherstripping has to hold against the Santa Ana gusts that scream down from the San Gabriels. Altadena homeowners have dealt with doors that bind in July and rattle in October long enough. We fix that for good.

Every technician who walks onto an Altadena property is background-checked and in uniform. We measure every opening twice before ordering a door, because an eighth of an inch matters when you’re fitting a fire-rated slab into an old Craftsman frame. A live person answers our phone 24 hours a day, seven days a week. Call at 6:00 a.m. on a Sunday and you’ll get a human voice, not a menu.

We’ve already done the work on homes from the Meadows up through the trees off Canyon Crest and Alzada Road, and we’ve seen what county inspectors look for on post-fire rebuilds. That local knowledge keeps your project moving. It’s why homeowners in Altadena call us back when they need a matching door on another part of the house.

Our Door Installation Services in Altadena

We install, replace, and rebuild doors throughout Altadena with an emphasis on fire-rated assemblies, Archwood-appropriate wood selections, and entries that stay square through decades of wind loading. Here’s what we handle most often.

Entry & Swing Doors

Swing doors are the workhorse of any Altadena front entrance, and they take the brunt of the weather here. A solid entry door on a properly shimmed jamb will last 30 years or more. One hung out of square on a racked frame will bind before the first winter ends. We rebuild the rough opening when it needs it, then install the door to factory spec with the manufacturer’s thresholds and weatherstripping rather than whatever was left over from the old one. For homes in the fire zone, we default to a 20-minute fire-rated slab or better, with impact-rated dual-pane tempered glass if the design calls for a lite.

Entry & Swing Doors

Arched & Custom Doors

Altadena has a lot of original Craftsman bungalows and Spanish Colonial Revivals from the 1910s through the 1940s, and many of them have arched entryways you won’t find at a home center. We order arched slabs from manufacturers like PGT and CGI that build true architectural shapes, not cut-down rectangles. A custom arched door on an Altadena Craftsman needs the radius matched to the existing jamb, and we template every curve on site before the order goes in. These doors typically run $3,200 to $7,800 installed, depending on the radius size and whether the frame needs converting for a fire-rated assembly.

Arched & Custom Doors

Double & French Doors

Sliding and patio doors are common on Altadena rear patios and sunrooms, particularly on the Spanish Colonial and ranch homes east of Lake Avenue. They fail in predictable ways here: the passive door drifts as the Santa Anas cycle pressure against the frame, and the astragal starts leaking warm air in from the foothill afternoon heat. We install French and double doors with reinforced center posts and adjustable hinges, and we set them so both slabs meet clean with even reveal. Prices for a double door system in Altadena generally fall between $2,800 and $6,500, including fire-rated frames when the county needs them.

Double & French Doors

Bifold & Folding Doors

Folding doors look right on a hillside home where the back wall opens to the San Gabriel ridgeline. But they’re heavy, and a hillside lot with sloped access means planning the lift and carrying path before ordering anything. We scope the haul route on every Altadena bifold job. If the driveway can’t take a lift, we carry the panels in by hand and assemble on site. Bifold installations run from $4,000 to $9,000 in Altadena, and we won’t quote one without walking the path from the street to the opening first. That’s the only honest way to price it.

Trusted Brands We Service in Altadena

TruePane is an authorized installer for more than a dozen manufacturer lines, including, PGT, and CGI. For Altadena specifically, we stock most of our energy-efficient replacement parts from PGT, Ply Gem, and CWS because those lines hold up to the heat cycling and wind pressure we see at the base of the San Gabriels. We quote manufacturer options side by side on paper so you see the actual cost difference without a sales pitch. Both warranty layers get registered in writing before our truck leaves your driveway, every time.

Common Door Installation Problems We See in Altadena Homes

  • Plan-check rejection on county permits. Contractors submit city of Pasadena forms instead of the LA County application and omit the Chapter 7A fire-glazing callout. The plan checker bounces it, and the rebuild stalls for two to three weeks. We’ve walked multiple Altadena projects back through the WUI review to fix exactly this.
  • Door jambs racked out of square by Santa Ana wind. Repeated pressure spikes from the mountain corridor push the frame out of true, the slab binds, and the weatherstripping shreds within one season. A properly reinforced jamb and through-bolt anchoring fixes the root cause instead of re-hanging the same door on a crooked frame.
  • Standard dual-pane glass delaminating on west-facing doors. The foothill sun on Altadena’s western exposures cycles surface temperatures hard enough to crack the seal on a standard IGU within five years. Fire-rated tempered glass with a better edge seal holds up far longer.
  • Outbuilding and detached ADU doors failing inspection. If a rebuilt shop or ADU was hung on an old septic or well setback and grading shifted the drainage, the final inspection fails even with a fire-rated frame. We verify the setback paperwork and confirm the door opening hasn’t shifted before we install.

Pricing for Door Installation in Altadena, CA

You should know what to expect before anyone hands you a quote. Here are honest ranges for the Altadena market, based on jobs we’ve scoped and completed in 91001:

  • Single entry door replacement: $1,400 to $3,200
  • Fire-rated entry door (20-minute minimum, Chapter 7A compliant): $2,400 to $5,500
  • Double or French door system: $2,800 to $6,500

  • Arched or custom door with architectural frame work: $3,200 to $7,800
  • Storm door installed: $450 to $1,100

What moves the number is the frame condition, whether the opening needs re-framing for a fire-rated assembly, and how difficult the access is on a hillside lot. We scope every Altadena job in person before we quote, so the number on paper is the number you pay. Call (888) 635-0804 to schedule your free estimate. We’ll measure, check the county permit path, and give you a written line-item quote.

What Altadena Customers Say

Trusted by homeowners across Altadena and surrounding areas.

★★★★★

"A casement crank had stripped and the sash was swollen shut. The technician, Ray, fixed the crank on the spot and only then talked about replacement for the three windows that were genuinely done. That is why the whole street uses them now."

Eleanor G. · Verified customer
★★★★★

"French doors to the patio, custom size because this house was built in 1961 and nothing is standard. Measured twice, three weeks to fabricate like they warned, and the install day they laid runners over my floors without being asked."

Marie S. · Verified customer
★★★★★

"Our bay window had rotted at the sill and two other outfits wanted to talk us into a flat picture window instead. TruePane rebuilt the opening and matched the original look. Neighbors have knocked on the door about it."
