Fast, Reliable Windows & Doors Across Whittier
Window and door replacement in Whittier runs $4,500 to $15,000 for a typical home, and impact-rated window installation for hillside and fault-line properties runs $8,000 to $25,000. Those numbers include something most national outfits skip: the seismic reality of a city built on an active fault. If you’re in 90601, 90609, 90610, or 90612 and your wood sashes are painted shut or your patio door binds every summer, call Barrett & Sons Construction at (877) 610-1318. We’re owner-operated by Tom Barrett, we pull permits on every eligible job, and we’ve been working on Whittier homes long enough to know which ones need more than a swap.
Why Barrett & Sons Construction Is Whittier’s Preferred Windows & Doors Company
Tom Barrett founded this company in 1998 and his sons run the crews. That means the name on the estimate is the name on the truck, and the person who answers the phone knows what a Friendly Hills cut-and-fill lot does to a door frame over thirty years. We serve Whittier with a live person on the line 24/7, not a call center reading a script. When you call about a failed window on a pre-WWII bungalow near Uptown, we know why it failed and what the inspector will want to see when we open the wall.
Our 90-Day Done Right Promise is written on every contract. If something isn’t right, one call brings Tom back. We also offer a Free Second Opinion on Any Written Estimate. If a national window company quoted you Andersen or Marvin and delivered something else, bring us that paperwork. We’ll tell you what it’s really worth and what it will take to fix it. No trip charge inside the county. Seniors and veterans get 10% off, permanently.
Our Windows & Doors Services in Whittier
Impact Windows & Doors
Whittier sits directly on the Whittier Fault. That’s not trivia, it’s the reason we recommend impact-rated windows and doors for any replacement on a pre-1940 raised foundation. The 1987 Whittier Narrows earthquake shook homes hard enough to rack window frames and send glass into living rooms. Modern impact windows are engineered to hold their frame under lateral load, and the code in Whittier’s hillside and historic districts now expects exactly that. We carry impact-rated product lines and coordinate with seismic retrofit work so the opening, the framing, and the bolting all meet the same standard.

Window Replacement
In Whittier’s older core around Uptown, original wood double-hungs in Craftsman bungalows are often painted over with lead-based paint and sealed shut. That’s not a simple swap. It requires containment, test kits, and abatement before we touch the opening. We handle that end to end, and we pull the permit. On 1950s and 60s tract homes in the eastern ZIP codes, the usual job is replacing failed single-pane aluminum sliders with vinyl or fiberglass units that actually seal against Santa Ana wind. A full-house window replacement in Whittier runs $4,500 to $15,000 depending on count and frame condition.

Sliding & Patio Doors
Hillside homes in Friendly Hills and Whittier Hills have a specific problem: expanding clay soil from cut-and-fill lots racks door frames out of square over time. A new pre-hung patio door will bind in a distorted rough opening unless the opening is re-plumbed and the subfloor leveled first. We do that. On one Friendly Hills lot, our crew replaced original 1960s aluminum sliders with impact-rated vinyl windows and a new patio door, staging materials on a plywood runway over a failing slope and coordinating sign-off with the city’s hillside grading reviewer. We kept the shared Whittier Driveway & Pavers clear by stacking demo in a neighbor-approved zone and finished with a punch list walkthrough before day seven.

Custom Windows & Doors
Spanish Colonial Revival homes in Whittier often have arched or rounded openings that stock windows won’t fit. Custom sizing is the only route, and it’s slower than off-the-shelf. We order exactly to the opening dimensions we measure on site, and any change to that order arrives as a written change order before it’s placed. The allowance isn’t on paper if it isn’t on paper. That’s true for custom windows, custom doors, and everything else we install.

Trusted Brands We Service in Whittier
We install Andersen and Marvin windows, and we stock the weatherstripping, rollers, and balances that keep the most common Whittier window brands functional. If you’ve got an older Andersen or Marvin product that’s out of warranty and the manufacturer won’t answer, we’ll still look at it. We also work with Schluter trim systems on doors and thresholds in wet areas. Our Windows & Doors team carries parts that national installers don’t, because we’re the ones doing the callback when a slider sticks six months after another contractor walked away.
Common Windows & Doors Problems We See in Whittier Homes
- Lead-painted sashes in pre-WWII bungalows. Windows in Whittier’s Craftsman and Spanish Revival homes built before 1940 were painted with lead-based paint. Renovation now requires containment and abatement. We test, contain, and document before cutting anything loose.
- Santa Ana wind uplift on exposed hillside lots. Whittier sits at the inland edge of the San Gabriel Valley foothills, and Santa Ana wind events here are stronger and more sustained than in coastal LA. Poorly flashed window frames pull out of stucco, and water gets behind the opening. We re-flash with proper head and sill flashing, not just caulk.
- Racked door frames from expansive clay soil. Friendly Hills and Whittier Hills have known cut-and-fill issues where clay soil swells and shrinks with moisture. Doors bind, gaps open up, and locks stop lining up. We re-plumb the rough opening and level the subfloor before the new door goes in.
- Permit and retrofit coordination on raised foundations. Any window or door replacement on a pre-1940 raised foundation in Whittier should be coordinated with seismic bolting and cripple-wall bracing. The current retrofit standard expects it, and your inspector will ask about it. We schedule the work so the retrofit and the window replacement happen in the right order.

| Service | Price Range |

What moves the number: how many windows, whether the home is on a raised foundation needing seismic coordination, whether lead abatement applies, and whether custom sizing is required for arched or non-standard openings. Hillside access adds staging cost because materials can’t always sit in the street. Every quote includes a written scope, a written allowance for materials, and a written change order process before anything changes. Call (877) 610-1318 for a free estimate. We’ll walk the house with you and tell you what the inspector will want to see.

FAQs - Windows & Doors in Whittier
Not always, but if the home is in a designated historic district or shows signs of foundation movement, the city may require an engineer’s letter before issuing a permit. We’ll tell you if yours does. The permit inspector works for you, not for me, so we’d rather flag it early than find out at framing inspection. Call (877) 610-1318 and we’ll help you figure out what your specific house needs.
We set up containment at the property line, stage materials in your yard or driveway, and sweep and magnet-pick the job site daily. On tight Whittier lots with shared driveways, we coordinate demo stacking and dumpster placement with your neighbor before anything gets moved. If a neighbor has a concern, we want to hear it before it becomes a dispute.
Yes, in most cases. We hand-carry panels on a plywood runway or use a lift only when the slope won’t allow safe access. We plan access before we quote so the price reflects reality. On one Friendly Hills job, the entire door and window package went in over a protected slope with no crane and no street closure.
For a typical 1950s tract home in 90604, a full window replacement runs $4,500 to $9,000 for standard double-hung or slider replacements in average condition. If the original frames are rotted or out of square, expect the higher end. Impact-rated upgrades jump the price to $8,000 and up. Get an exact number with a free estimate at (877) 610-1318.
Yes. Changing a window opening to a door opening is structural work, and Whittier requires a permit. The framing, header, and shear requirements all change, and the hillside grading reviewer may get involved on slope lots. We pull that permit. We don’t ask you to. Call (877) 610-1318 for a free estimate that includes the permitting scope.
