Fast, Reliable Windows & Doors Across Sherman Oaks
If you’re searching for Windows & Doors work in Sherman Oaks, you’re likely weighing two things: a fair price and a crew that will actually stand behind the job. Window replacement in Sherman Oaks typically runs $4,500-$15,000 depending on count and frame material, while a full impact window installation for a mid-century ranch home usually falls between $8,000-$25,000. Door installation is less, often $1,200-$4,800 per opening for a quality pre-hung unit with hardware. We’re Barrett & Sons Construction, owned and operated by Tom Barrett since 1998, and we’ve done enough work in the valley to know that Sherman Oaks homes have their own set of problems: old single-pane aluminum frames, dry-rotted sills on post-WWII tract homes, and years of sun exposure that warps cheap doors and makes locks stick. Call us at (877) 610-1318 and we’ll talk through what you’re seeing, then schedule a free estimate to look at it in person.
Why Barrett & Sons Construction Is Sherman Oaks’s Preferred Windows & Doors Company
Tom Barrett’s name, address, and license number are published and verifiable. That matters more than it sounds. Plenty of contractors will quote windows over the phone for a house off Van Nuys Boulevard, then send a sub they’ve never met. Tom’s sons run the crews. They’re background-checked, uniformed, and they carry the Barrett & Sons name on their shirts, not some mystery brand off a van. When a Sherman Oaks homeowner on a hillside street south of Ventura asks who’s coming to their door, we can tell them exactly who, and when.
We’ve worked on the 1940s-1960s tract homes that dominate the valley floor here, the tuck-under apartment buildings along Ventura Boulevard, and the custom hillside homes below Mulholland Drive. Each has different window and door complications. A flat-floor tract home usually needs straightforward replacement, but a hillside lot with expansive soils often means we’re dealing with a settling frame that won’t accept a stock-size unit. We measure, we write it down, and we don’t guess. Every scope, every allowance, every price change arrives as a written change order before work happens. No surprise invoices at the end. Because an allowance that isn’t on paper is a surprise waiting for a date.
We don’t publish a star rating here because the number changes, and frankly you should look it up yourself. Ask anyone on your street, or look up the license number yourself. That’s the point. We’re not a franchise dispatching strangers from a call center. We’re the Window and Doors in Sherman Oaks crew your neighbor is more likely to recognize at the hardware store.
Our Windows & Doors Services in Sherman Oaks
Window Installation
New window installation in Sherman Oaks means working around stucco exteriors, lath-and-plaster interior walls, and in some cases the city’s seismic retrofit requirements if the property falls under the soft-story ordinance. We remove the old unit, flash the opening correctly so water doesn’t find its way into the wall cavity, and set the new frame square. On hillside homes south of Ventura Boulevard, we pay close attention to how the existing structure has moved over the decades. A window that’s installed plumb in a house that isn’t plumb anymore will bind within a year.

Door Installation
A front door in Sherman Oaks takes a beating. The inland heat means south-facing doors expand and contract through a 40-degree daily swing in summer. We see warped slabs, sagging hinges, and strike plates that no longer line up. We install pre-hung entry doors, interior doors, and French doors with proper weatherstripping and threshold sealing so you don’t feel the draft in January or the heat in August. Sliding and patio doors are a particular focus, especially on ranch homes where the original aluminum sliders from the 1950s and 60s are long past their useful life.

Window Replacement
Most Sherman Oaks window replacement jobs we do involve pulling out old aluminum single-pane frames and installing dual-pane vinyl or fiberglass units. The difference in summer comfort is immediate, and the sound reduction on busy streets like Burbank Boulevard or Sepulveda is noticeable. Replacement ranges from $4,500 on a smaller ranch to $15,000 for a whole-home job with custom sizing. We handle the permit when one is required, and the inspector signs off before we consider the job done.

Impact Windows & Doors
Impact windows and doors aren’t a hurricane consideration in Sherman Oaks, but they matter for a different local reason: the 1994 Northridge earthquake damaged a lot of the valley’s window inventory, and homeowners who lived through it tend to think about glass differently. Impact-rated units add structural strength, noise reduction, and in many cases insurance savings. We install impact windows and impact sliding glass doors from PGT and CGI, sized to your existing openings and tested to current Dade County standards for those who want the extra layer. Installation typically runs $8,000-$25,000 depending on count and access.

Trusted Brands We Service in Sherman Oaks
We install Simonton, PGT, and CGI windows and doors, and we don’t push mystery brands. You can look up the manufacturer, read the warranty, and know exactly what you’re paying for. For Sherman Oaks customers, we keep common replacement parts on hand: rollers, balances, weatherstripping, and latch hardware. That means a sticky slider on a Saturday doesn’t mean waiting a week for a part to ship. If it’s a brand we service, we can usually get it moving again quickly. The same goes for hurricane shutters and protection systems if you’re adding them to a hillside home that gets direct afternoon sun and wind up against the foothills.
Common Windows & Doors Problems We See in Sherman Oaks Homes
- Dry-rotted wood sills on post-WWII tract homes: The 1940s-1960s single-family homes on the valley floor were built fast, and many original sills were never properly flashed. Decades of winter rain followed by 100-degree summer heat have rotted them through. We replace the framing, not just the window.
- Warped south-facing doors and windows: Sherman Oaks sits in the inland San Fernando Valley heat pocket, regularly hitting 100-108°F in summer. That’s 20 degrees or more above coastal temperatures, and it warps unshaded doors and window frames faster than most national installers expect. We spec materials accordingly.
- Stuck rollers and failed seals on original aluminum sliders: The 1960s and 70s apartment stock along Ventura Boulevard and side streets is full of original sliders that no longer glide and no longer insulate. We rebuild the track, replace the rollers, and where needed swap the sash for a modern dual-pane unit.
- Seismic movement and settling on hillside lots: Homes south of Ventura Boulevard toward Mulholland sit in landslide-prone hillside areas under the city’s Hillside Ordinance. Frames shift, doors go out of square, and windows crack at the corners. We check the structure before we set a new unit, because installing into a moving frame just means doing it twice.

FAQs - Windows & Doors in Sherman Oaks
For an estimate, usually within a few business days depending on current scheduling. We don’t promise same-day estimates because Tom or one of his sons will be the one standing at your door, not a sales rep with a tablet. Call (877) 610-1318 and we’ll tell you straight what the next open slot looks like.
Yes. We work the flats north of Ventura, the hillside streets south toward Mulholland, and the apartment corridor along Ventura Boulevard. That includes ZIP codes 91403, 91413, 91423, and 91495. Some hillside lots require LADBS soils and grading review even on modest window or door work, and we handle that paperwork rather than hoping nobody notices.
A broken window or a door that won’t close isn’t just inconvenient, it’s a security issue. We prioritize calls where the home is exposed or unsecured. A live person answers the phone 24 hours a day, 7 days a week. We’ll schedule as soon as a crew is available and tell you honestly what the timing looks like. For exact timing, call (877) 610-1318.
Part of it is the housing stock. Sherman Oaks has a lot of older stucco homes with lath-and-plaster interiors, which cost more to patch and match than drywall. Part of it is hillside access south of Ventura, where parking a truck and staging materials takes longer. The ranges we quote, $4,500-$15,000 for typical replacement, account for those variables. We’ll give you a written line-item estimate so you can see exactly where the money goes.
Every job we finish is backed by our written 90-Day Done Right Promise. If it’s not done right, Tom comes back and makes it right, one call. Manufacturer warranties on Simonton, PGT, and CGI products are separate and we’ll walk you through the paperwork. If another contractor gave you a written estimate for the same scope, bring it in and we’ll give you a free second opinion. Call (877) 610-1318 to set that up.
