Fast, Reliable Windows & Doors Across Altadena
If you’re rebuilding or repairing a home in Altadena after the Eaton Fire, or simply replacing worn-out windows on a 1940s ranch, you need a contractor who understands what this community has been through and what Los Angeles County now requires. Window replacement in Altadena runs roughly $4,500 to $15,000 depending on the count, material, and whether you’re in a fire-hardening zone. Impact window installation, which many homeowners now pursue along the mountain front, typically lands between $8,000 and $25,000 for a full home. Call (877) 610-1318 and we’ll walk your property with a written estimate, no trip charge inside the county.
Why Barrett & Sons Construction Is Altadena’s Preferred Windows & Doors Company
Barrett & Sons has been owner-operated since 1998, and Tom Barrett’s name is on the truck, the contract, and the license. When Altadena homeowners call, they reach a live person, not a call center. We work throughout 91001 and 91003, from the streets off Lake Avenue up to the foothill lanes near Rubio Canyon, and we know which approvals come from LA County Public Works and which fire-safety provisions the Wildland-Urban Interface codes demand.
Our crews have replaced countless windows in pre-war Craftsman bungalows and mid-century homes where old wood sashes had warped or single-pane glass had fogged beyond repair. Altadena clients often tell us a previous contractor quoted one number on the phone and delivered another at the door. Our answer is simple: every scope, every allowance, every price change arrives as a written change order before work happens. Tom lives close enough to want a neighbor to recognize him at the hardware store on Saturday. That matters.
Here’s what else sets us apart in Altadena. We pull permits and get inspections signed on every eligible job, because LA County authorities are particularly rigorous about window and door work in the VHFHSZ, especially where fire-resistant materials and ember-resistant vents apply. Our installers are background-checked and uniformed on every visit. And every project carries the 90-Day Done Right Promise in writing: if it’s not done right, one call brings Tom back.
Our Windows & Doors Services in Altadena
Window Installation in Altadena
New window installation across Altadena often means working in homes ranging from 1920s Craftsman bungalows to 1950s ranch houses with original steel or aluminum frames. We install modern, double-pane windows that hold conditioned air better than anything these old frames could manage. In the burn zones and along the alluvial fan near the San Gabriels, we also recommend reviewing your window schedule against California’s Very High Fire Hazard Severity Zone requirements, because some replacements now qualify for fire-resistant glazing and frame upgrades you’ll want to consider before you sign a contract. Every estimate spells out what you’re buying in writing. Call (877) 610-1318 to schedule one.

Door Installation in Altadena
We install entry doors, exterior doors, and interior doors throughout Altadena, from the neighborhoods off East Loma Alta Drive to the flats near Altadena Drive, and we also handle Altadena Kitchen Remodeling. A poorly hung entry door in an older wood-frame home lets in drafts, pests, and the occasional Santa Ana dust storm that blows through the foothill neighborhoods. New factory-finished doors with proper weatherstripping make a bigger comfort difference than most people expect. And if you’re rebuilding after the fire, an exterior door in a designated hazard zone will likely need to meet County fire-hardening standards before an inspector signs off.

Window Replacement in Altadena
Window replacement in Altadena typically runs $4,500 to $15,000 for a full home, with impact-rated products at the higher end. Many of the older homes still have single-pane wood sash windows that are a poor match for summer heat coming off the mountainside and winter evening drops drifting down from the canyons. Replacing them with vinyl or fiberglass double-pane units usually tightens temperature swings immediately. We also coordinate with the full Windows & Doors team to match existing trim styles, so a 1930s Spanish Colonial doesn’t wind up with cookie-cutter modern frames that look rented.

Impact Windows & Doors in Altadena
Altadena sits directly against the San Gabriel front, where Santa Ana and Diablo wind events have driven some of the most destructive fires in California history. Impact windows and doors are engineered to resist wind-borne debris and reduce ember intrusion, and we install them regularly for homeowners who want more than a pretty frame. On a replacement, impact-rated glass typically adds significantly to the per-opening cost, but many Altadena homeowners consider it a permanent insurance reduction plus a physical security upgrade. We carry PGT and similar premium impact lines and will show you the product specs before any order goes in.

Trusted Brands We Service in Altadena
We install Simonton, Ply Gem, and PGT windows and doors, and we stock the local trim, hardware, and common replacement parts Altadena customers need for faster turnarounds. These aren’t mystery brands off a van. You can look up the product lines, compare certifications, and read the manufacturer specs yourself. Whether you need impact sliding glass doors or a simple vinyl window replacement, we’ll show you the actual brand name in the estimate, not a vague “premium product” line item. That’s how Tom has done business since 1998.
Common Windows & Doors Problems We See in Altadena Homes
- Fogged and failed double-pane seals on 1950s and 1960s homes. Altadena’s older housing stock often has aluminum-framed windows that sat under decades of direct foothill sun. Once the seal fails, the glass fogs permanently, and you’re paying for a window that does nothing but leak light.
- Warped wood sashes in Craftsman and Spanish Revival homes. Humid winter storms moving off the mountains alternate with dry Santa Ana blasts. Old-growth wood can’t absorb that cycle forever, and eventually the sash binds against the frame or won’t lock.
- Ember-vulnerable venting and weatherstripping in the foothill zones. In the VHFHSZ designations above the flats, we routinely see gaps that wouldn’t matter in Pasadena but could become ember paths in a wildfire. Loose-fitting window screens and vented frames can let embers reach combustible surfaces.
- Fire-rebuild permitting delays unrelated to the actual window work. Windows and doors on a fire-rebuild don’t get installed in isolation. Soil testing, contaminated soil remediation, and geotechnical re-evaluation on alluvial-fan lots all have to clear LA County before the final finish trades can go in. We sequence window and door work to match that reality and avoid scheduling promises nobody can keep.
Pricing for Windows & Doors in Altadena, CA
For planning purposes, window replacement in Altadena generally lands between $4,500 and $15,000 for a standard single-family home. Impact window installation, which is becoming the default request along the mountain front, runs $8,000 to $25,000 depending on how many openings you have and which product line you choose. Sliding and patio door replacements typically fall inside those broader ranges, with premium impact-rated options pushing higher. The single biggest cost driver on Altadena rebuilds is fire-hardening compliance: Class A windows, ember-resistant venting, and frame materials the County accepts. Our estimates are free, written line-by-line, and include every allowance on paper. Call (877) 610-1318 for a number specific to your home.
