Fast, Reliable Windows & Doors Across Lomita
Window and door work in Lomita comes down to one word: salt. The marine layer off the Pacific rolls in most nights, sits over the city until late morning, and slowly eats anything steel, zinc-coated, or cheaply sealed. We’re Barrett & Sons Construction, and when we quote a window replacement in Lomita, we quote the coastal-spec version of the job because we’ve seen what the inland-spec version looks like after eight years here. Call (877) 610-1318 and we’ll walk your house, look at your existing frames and flashing, and give you a written line-item estimate for free.
Why Barrett & Sons Construction Is Lomita’s Preferred Windows & Doors Company
We’ve been doing Windows & Doors work in the South Bay long enough to know that Lomita is different from Torrance, and not just because city hall runs on its own calendar. Homes here were built in the 1940s through 1960s, mostly stucco bungalows and ranch-style houses on modest lots. The original windows were almost always single-glazed wood sash or early aluminum frame. The original patio doors were aluminum sliders with steel tracks. None of that was designed for the salt air that settles over Lomita every morning.
Tom Barrett founded this company in 1998, and he still answers his own phone. The crews that come to your house carry the Barrett & Sons name with them, and they’re background-checked and uniformed every visit. We don’t dispatch strangers. We pull permits on every eligible job because Lomita has its own building department with its own inspection calendar, and we’d rather schedule around city hall’s actual availability than pretend the process doesn’t exist. Every price change arrives as a written change order before a nail moves. And every job is backed by our 90-Day Done Right Promise: if it’s not done right, Tom comes back, one call.
Our Windows & Doors Services in Lomita
Window Replacement
Most Lomita homes still have their original 1940s-1960s wood sash or early aluminum frames. The wood units stick because the marine layer keeps the wood damp through late morning, then the west-facing units bake dry in afternoon sun. The aluminum frames pit and corrode around the weep holes from the salt air, and the glass seals fail within seven to ten years. We replace both with materials spec’d for coastal exposure. A typical window replacement in Lomita runs $4500-$15000 depending on count, frame material, and whether we have to reframe oversized openings. The cheap quote you’ll get from a big-box installer won’t include the stainless hardware and sealed joints this city actually needs.

Door Installation
Exterior doors in Lomita fail at the threshold and the hinges. Salt-laden condensation sits against the jamb, the wood rots where the weatherstripping meets the bottom plate, and the door won’t latch by year eight. We install doors with marine-grade hardware, stainless hinges, and thresholds bedded in polyurethane caulk. A new front or rear door in Lomita typically runs between the cost of the slab, the frame, and the hardware, and we’ll walk you through every line item before we order anything.

Impact Windows & Doors
Lomita sits close enough to the coast to get wind-driven salt spray but far enough inland that homeowners sometimes forget the exposure is real. Impact windows and doors do two things here: they hold up to wind and debris, and they’re built with heavier frames and better seals that stand up to the salt better than builder-grade units. A full impact window installation in Lomita runs $8000-$25000. We’ll give you the exact number in writing before you sign anything.

Sliding & Patio Doors
This is the one thing that keeps a Lomita homeowner up at night. The old aluminum sliders have steel tracks that rust through, rollers that grind on wind-blown ocean sand, and jambs that rot where the salt holds condensation against the wood. A customer near Eshelman Avenue and 255th Street had a 1952 bungalow with a patio door so corroded the track had rusted completely through. We reframed the opening with a load-bearing beam to fix a half-inch of header settlement, then set a marine-grade anodized aluminum door with stainless rollers and copper flashing. That change added $1,200 to the scope, and it was the right decision. A custom marine-grade sliding or patio door in Lomita runs $5000-$18000.

Trusted Brands We Service in Lomita
We install materials you can look up, not mystery brands off a van. On windows and doors in Lomita, we work most often with Andersen and Marvin, and we specify them because their marine-grade finishes hold up to this city’s salt air better than the box-store lines. We also carry GAF for any roof-to-wall flashing work tied to window and door openings, because the intersection between the roof and the wall is where most coastal leaks start. If you have another brand in mind, tell us on the call. We’ll give you an honest read on whether it’s built for Lomita or built for a dry inland zip code.
Common Windows & Doors Problems We See in Lomita Homes
- Aluminum frame pitting and glass seal failure. The weep holes on 1960s-era aluminum windows corrode from the salt air, the sashes bind, and the double-pane seals fail. We see this on nearly every original aluminum window in zip code 90717.
- Wood sash warping from daily moisture swings. The marine layer holds moisture against wood windows all morning, then the afternoon sun hits the west-facing walls. Repeat that cycle a few thousand times and the sashes won’t open or close right.
- Patio door tracks packed with sand and salt. The wind off the coast carries fine sand and salt grit that grinds rollers down, chews the vinyl weatherstripping, and leaves the door unable to latch. If your patio door sticks every morning and loosens by noon, you’re not imagining it. That’s the Lomita marine layer doing exactly what it does.
- Rotted jambs from condensation against wood. The salt in Lomita’s air holds condensation against any unpainted or underspecified wood surface. We routinely replace patio door jambs that look fine on the surface and are hollow behind the trim.
Pricing for Windows & Doors in Lomita, CA
The coastal-spec version of a window or door job in Lomita always costs more than the inland-spec version. That’s not markup, it’s materials. Stainless steel fasteners instead of zinc, copper flashing instead of generic aluminum, polyurethane caulk instead of acrylic, and marine-grade finishes on frames and hardware. The cheap spec will fail within a decade here and you’ll pay for the job twice. A real Lomita price looks like this:
| Service | Typical Price Range in Lomita, CA |
|---|---|
| Window Replacement | $4,500 - $15,000 |
| Impact Window Installation | $8,000 - $25,000 |
| Sliding & Patio Doors (custom, marine-grade) | $5,000 - $18,000 |
These are our honest ranges for Lomita’s market, not a national average. Your exact price depends on how many openings, the frame condition, whether we have to reframe any settled headers, and what kind of existing flashing is in the wall. We’ll give you a written line-item quote with every scope item and allowance on paper before we ask for a signature. Call (877) 610-1318 to schedule your free estimate.

FAQs - Windows & Doors in Lomita
Lomita operates its own independent building department separate from LA County, and the plan check and inspection calendar runs on a smaller staff and a slower turnaround than what Torrance or Harbor City contractors are used to. That means a window replacement that could sail through Torrance in a week might sit in Lomita’s queue for over a month. We schedule our Lomita jobs around city hall’s actual availability, not the homeowner’s guess, and we build that time into our schedule up front so you’re not surprised mid-project. Call (877) 610-1318 for an honest timeline based on the current Lomita permit calendar.
You need them. The salt-laden air that settles over Lomita every night corrodes zinc-coated and plain steel fasteners faster than almost any other climate in LA County. A vinyl window installed with zinc screws will look fine on closing day and start showing fastener rust at the corner joints within five to seven years. We specify stainless steel on every coastal-spec job because we’ve pulled the old windows out of enough Lomita walls to know what non-stainless looks like after a decade.
Expect to pay 15-25% more for the coastal-spec version of the job. That covers stainless steel fasteners, copper flashing instead of aluminum, polyurethane caulk instead of acrylic, and marine-grade finishes on frames and hardware that survive the salt. The inland-spec version saves money on day one and guarantees a replacement bill within ten years. We’d rather quote you the honest number once. Call (877) 610-1318 and we’ll show you both specs side by side in writing so you can decide with your eyes open.
If the frame is pitted and corroding around the weep holes, replacing the glass buys you a year or two before the sashes bind again. The salt in Lomita corrodes the aluminum itself, not just the seals. The glass replacement route works when the frame is structurally sound and the weep holes are clear. If your frame has visible pitting, chalky oxidation, or sashes that already bind, you’ll spend money twice by glass-swapping now and replacing the whole window in a few years. We’ll tell you which situation you’re in after we look at it, and the estimate is free.
Yes. The marine layer holds moisture against the track and jamb every night and into the morning, which swells the wood just enough to bind the door. The afternoon sun dries it out and the door loosens back up. It’s a daily cycle unique to coastal cities like Lomita, and over time it grinds salt and sand into the rollers and weatherstripping until the door won’t latch at all. That’s a fixable problem now, but it gets more expensive every year you leave it. Call (877) 610-1318 and we’ll come look at it, free.
