Fast, Reliable Windows & Doors Across Koreatown
Window and door replacement in Koreatown is a different animal than it is a mile west in Hancock Park or up the hill in Silver Lake. Most of the work we do here is in pre-1978 wood-frame apartment buildings, and a surprising number of those buildings fall under LA’s mandatory soft-story seismic retrofit ordinance, Ordinance 183893. That means what starts as a simple window swap can turn into structural reinforcement the moment a wall gets opened. We know that going in, we scope for it, and we put every allowance in writing before we pull a permit. If you own or manage a building in 90005 and the windows are sticking, fogged, or leaking, call Tom Barrett directly at (877) 610-1318 and we’ll give you an honest read on what the job actually involves.
Why Barrett & Sons Construction Is Koreatown’s Preferred Windows & Doors Company
We’re an owner-operated shop. Tom Barrett founded the company in 1998, and his sons run the crews. When we work in Koreatown, the person who shakes your hand at the walkthrough is the same person who signs the change orders and stands behind the work. That matters in this neighborhood, where a lot of building owners have been burned by out-of-area contractors who quote one price on the phone and show up with a different one after the wall is open.
Koreatown is a dense, older, mostly multifamily neighborhood. The housing stock is largely 2-to-4-story Spanish Colonial Revival and mid-century stucco walk-ups, many with the open ground-floor carports that make them soft-story buildings under the city’s retrofit ordinance. We’ve worked on these buildings. We know that a window replacement on the ground floor of a tuck-under parking building is not the same as a window replacement in a single-family bungalow. We scope for the structural work that the ordinance may require, and we write those allowances into the contract before we start. That’s not something every contractor does, and it’s the reason owners in Koreatown call us back.
Calls are answered by a live person, 24/7, not a voicemail box. No trip charge inside the county. Free second opinion on any written estimate. And every completed job carries our 90-Day Done Right Promise: if it’s not done right, one call brings Tom back.
Our Windows & Doors Services in Koreatown
Our Windows & Doors team handles the full scope of replacement, installation, and custom work across Koreatown. Here’s what we do most often in this neighborhood:
Window Replacement
Most Koreatown apartment buildings and older single-family homes still have original wood windows or early aluminum sliders. The wood has rot at the sills, the aluminum frames are thermally shot, and the stucco around the openings is cracked and letting water behind the flange. We replace these windows with properly flashed, correctly shimmed units sized to the existing rough opening, and we inspect the headers and king studs before any new window goes in. A typical window replacement in Koreatown runs $4,500-$15,000 depending on building type and how many openings are involved.

Door Installation
Entry doors on Koreatown’s older buildings take a beating. The ground-floor doors on Wilshire and Western catch afternoon sun and swelling, and the security doors on multi-unit walk-ups are often misaligned from years of hard use. We install properly hung, weather-stripped entry, patio, and unit doors, and when we’re working in a soft-story building, we check the surrounding framing before we set the jamb. You don’t want a new door in an opening that’s carrying more load than it was built for.

Impact Windows & Doors
Impact-rated windows and doors aren’t just for hurricane zones. In Koreatown, they deliver real benefits: better sound attenuation on dense residential blocks, stronger security on ground-floor units, and far better thermal performance than early aluminum. We install impact windows and sliding glass doors from manufacturers we trust, and we handle the structural review that comes with heavier laminated glass in older wood-frame openings. Impact window installation in Koreatown typically runs $8,000-$25,000 for a standard multi-unit scope.

Custom Windows & Doors
Some of the Spanish Colonial Revival buildings in Koreatown have arched window openings, radius corners, and original wood details you don’t find in tract housing. We do custom window and door fabrication for these buildings, built to match existing sightlines and preserve the character of the structure while meeting current code. That’s work that requires a shop that knows the neighborhood’s building stock, not a national outfit that sells one size in three colors.

Trusted Brands We Service in Koreatown
We don’t install mystery brands off the back of a van. Barrett & Sons carries Andersen and Marvin windows because those are companies whose warranties hold up and whose materials you can look up yourself. On hardscape-adjacent door threshold and patio door work, we’ve also specified Belgard and Techo-Bloc pavers when the entry needs a decent landing or step detail. We keep common replacement parts and hardware on hand for faster turnaround in Koreatown, and when a specialty component needs to be ordered, we tell you the lead time before you sign anything.
Common Windows & Doors Problems We See in Koreatown Homes
- Rotted, undersized headers in pre-1978 wood-frame openings. We open the wall to replace a window and find the header is a 2×4 laid flat, or it’s rotted from decades of stucco cracking and water intrusion. If we put a heavier window in that opening without reinforcing the header, the opening sags and the window binds within a year. We fix the framing and write it into the change order before any glass goes in.
- Failed waterproofing at window flanges on party-wall buildings. Koreatown’s dense blocks mean many buildings share walls. A window replacement on a shared wall often exposes the neighbor’s framing and failed tar paper. Without a pre-scope inspection and a written allowance for waterproofing repairs, you inherit someone else’s leak. We scope these openings before we quote so there are no surprises.
- Dry rot from stucco cracks, even though the area doesn’t get much rain. Koreatown sits about 7 miles inland, in the hotter, drier air that the marine layer rarely reaches. That accelerates UV degradation on stucco cladding, and once stucco cracks, irrigation and occasional winter rain get behind the finish and rot the framing around window and door openings. We replace the rotted wood and the tar paper, not just the window.
- Ground-floor carport penetrations that were never properly flashed. The open ground-floor carports that define soft-story buildings in Koreatown create door and window penetrations in structural walls. Many of these were never flashed correctly when the building went up in the 1930s through 1960s, and the frames fail within a season if the original tar paper isn’t replaced. We inspect these areas as standard practice on any ground-floor replacement.
Pricing for Windows & Doors in Koreatown, CA
Line-item pricing is the only way to quote this work honestly. Here’s what we’re seeing in Koreatown as of this writing:
| Scope | Typical Koreatown Range |
|---|---|
| Impact Window Installation | $8,000-$25,000 |
| Window Replacement | $4,500-$15,000 |
These ranges assume a wood-frame apartment building or older single-family home typical of Koreatown. What moves the number is the condition of the framing behind the stucco, whether the building falls under the soft-story retrofit ordinance, and how many openings are involved. We give free estimates, and every estimate is a written, line-item scope. If something changes once the wall is open, you get a written change order before any additional work happens. That’s the only way we work. Call (877) 610-1318 and we’ll come out and put numbers on paper.

FAQs - Windows & Doors in Koreatown
Yes, in many cases they do. If your building falls under Ordinance 183893 and you’re replacing windows or doors on the open ground floor, the city may require structural upgrades like steel moment frames or plywood shear panels as part of the permitted scope. We scope for this before we pull the permit, and we write the structural allowance into the contract so you know what you’re facing. Call (877) 610-1318 and we’ll tell you exactly what applies to your building.
We sequence the work. On a 1950s walk-up near Wilshire and Western, our crew replaced a set of rotting, undersized windows in a fully occupied building. Once the walls were open, we found the original mudsill connections were just unbolted nails, and the city’s retrofit deadline meant we had to sequence our window rough-in around a steel moment-frame installation without displacing anyone. We wrote the added reinforcement into a change order, got the owner’s written approval, and passed the framing inspection before drywall went back up. Occupied-building work is our norm in Koreatown. Call (877) 610-1318 to talk through your building’s schedule.
A typical window replacement in a Koreatown wood-frame apartment unit runs $4,500-$15,000 depending on the number of openings, the condition of the surrounding framing, and whether the building triggers structural retrofit requirements. Impact-rated windows push toward the higher end. We provide a written line-item estimate before any work starts, so you know exactly what’s in the number. Call (877) 610-1318 for a free estimate.
The rot comes from stucco cracks, not rain. Koreatown sits in a hotter, drier air mass about 7 miles inland, and the UV exposure accelerates stucco degradation on the area’s older apartment stock. Once the stucco cracks, irrigation water from planter beds and whatever rain does fall gets behind the finish and sits against the wood framing. We replace the rotted wood and the failed tar paper when we do the window, not just the glass. Call (877) 610-1318 and we’ll inspect your openings before you commit to anything.
Yes, we can, but the work requires custom sizing and careful detailing to match the building’s character. Spanish Colonial Revival buildings in Koreatown often have arched or radius openings and original wood trim details. We fabricate custom impact windows and doors to fit those openings and match the existing sightlines, and we handle the structural review that heavier laminated glass requires in older wood-frame construction. Call (877) 610-1318 for a free estimate and we’ll walk you through the options for your building.
