Windows & Doors Services in Lomita, CA
Windows and doors in Lomita work harder than they do in most South Bay cities. The same harbor air that rolls over the Palos Verdes hills lands on your window tracks and door hardware, and after enough seasons, the evidence is in the pitting, the fogged glass, the door that needs a hip check to latch. TruePane Windows & Doors serves the 90717 ZIP with window installation, door installation, window replacement, impact windows, and custom work. We know what this climate does to a 1960s ranch house, and we price the work honestly. Call (888) 635-0804 and a person answers. That’s how we’ve always run the phone.

Why Lomita Homeowners Choose TruePane Windows & Doors
Our crews have worked in Lomita long enough to know the houses on the tabletop streets around Eshelman Avenue and the bungalow grid near Fleming Middle School were built in an era when a single-pane aluminum window was considered plenty. Homeowners in Lomita don’t call us because they saw an ad. They call because a neighbor off Woodward Avenue had their sliding door replaced and the job went clean: the crew was uniformed, background-checked, and measured every opening twice before a quote was written.
Dale Kessler founded TruePane in 2008 on a rule that still hangs in the shop: if the pane is not true, the job is not done. We register both manufacturer warranty layers in writing before the truck leaves your driveway, and everything we install is covered by the Done Right Promise. If it is not done right, we make it right. No paperwork fights, no fine print. Homeowners off Palos Verdes Drive North and in the small commercial streets near Lomita Boulevard deal with us the same way, because a square deal should not depend on your street address.
Windows & Doors Services We Offer in Lomita
Window Installation
New-construction and retrofit window installation across Lomita, sized for the original rough openings common to post-WWII tract homes. We install Andersen, Pella, and Marvin lines with the paperwork registered before we leave, and the install is held to The Keystone Standard.
Learn more about our Window Installation in Lomita.

Door Installation
Entry doors, interior doors, and pre-hung units installed square and sealed. In Lomita, where original door frames have settled for 60-plus years along Narbonne Avenue and Pine Boulevard, we expect to re-shim and re-seal.

Window Replacement
Full-frame and insert replacement for the aluminum single-panes that dominate Lomita housing stock. We quote manufacturer lines side by side on paper so you can see exactly what you’re buying, including CGI and ES Windows for coastal exposure.

Impact Windows & Doors
Impact-rated glazing and reinforced frames, tested for the wind and debris conditions that matter this close to the harbor. We’re an authorized installer for PGT and CWS impact lines, and both warranty layers get registered in writing.

Energy-Efficient Windows
Low-E, dual-pane, argon-filled, and Title 24-compliant options for Lomita homes undergoing renovation. Original 1950s fenestration almost never meets current California energy code, and we can get you there without a permit fight.

Sliding & Patio Doors
Aluminum and vinyl sliders, including multi-slide patio doors for the ranch homes that open onto small backyards from Cypress Street to 255th. We replace the rollers, the track, or the entire unit, and in Lomita the honest answer is usually the entire unit.

Glass Railing Systems
Tempered glass railings for decks, balconies, and staircases, installed to code with no corner-cutting. A clean sightline for the views that make the hill streets above Lomita Field worth the price.

Custom Windows & Doors
Non-standard sizes, unusual geometries, and matched millwork for the homes where nothing off the shelf fits. We measure, fabricate, and install custom work with the same Done Right Promise behind it.

Neighborhoods We Serve in Lomita
We work the whole 1.9 square miles of Lomita. Typical response time is one to three business days for estimates, and most repair and replacement work is completed in a single visit.
- Lomita Pines - the bungalow streets east of Lomita Boulevard with a high concentration of original 1950s window packages.
- Old Town Lomita - commercial storefronts and the older residential pockets off Narbonne Avenue.
- The area around Fleming Middle School - tight ranch homes with single-pane sliders facing the afternoon marine layer.
- The hill streets above Lomita Park - larger view lots where glass railing and impact-glass jobs are more common.
- West Lomita near the 110/405 corridor - homes closest to the port air path, where aluminum frames fail fastest.
Why Lomita’s Climate & Housing Affect Windows & Doors
Lomita sits just inland of the San Pedro and Wilmington harbor district. That is not a scenic detail. It means the marine layer carries salt-laden air off one of the busiest ports on earth, and it settles on every aluminum window frame and door track in the 90717 ZIP. Diesel particulate from port truck traffic mixes with that salt into a gritty paste that builds up in the tracks of original 1960s sliding doors. Our technicians know that pattern on sight: the rollers wear into flat spots, the track scratches, and the door starts to fight you. By the time a homeowner notices the drag, the repair usually costs as much as full-frame replacement, and the replacement will outlast the repair by decades.
Lomita’s housing stock compounds the problem. The city built out between 1945 and 1970 as a working-class bedroom community, and many of those ranch homes and California bungalows still carry their original single-pane aluminum windows. Those windows were never designed to last 55 to 70 years, and at this point they are past the point where any repair makes sense and far from current California Title 24 energy standards. When a homeowner off Pine Street does a permitted renovation, the original fenestration almost always must go. We quote the replacement the same way we quote the repair: with the numbers on paper, not promises in the air.
Pricing for Windows & Doors in Lomita
Honest numbers matter, so here is the range. Window replacement in Lomita typically runs $450-$1,100 per window for standard dual-pane retrofit work, depending on size and frame condition.

Impact-rated windows add 20-40% over standard dual-pane. Energy-efficient Low-E glass adds $70-$160 per window. We offer a $50 discount on any repair over $250, maintenance visits at $89, and a standing 5% discount for seniors and veterans. Every quote is a written line-item quote.

FAQs About Windows & Doors in Lomita
Window replacement in Lomita typically costs $450 to $1,100 per window for standard dual-pane retrofits, with full-frame work on original 1950s openings running $900 to $2,200 per opening. Impact glass adds 20 to 40 percent. The only way to know your exact number is a measurement, which is free. Call (888) 635-0804 to schedule one and get a written line-item quote.
If you live on the west side of Lomita near the 110/405 corridor or on an exposed hill street above Lomita Park, impact-rated glass from CGI or PGT is a reasonable investment. Lomita is far enough from the coast that wind-driven debris risk is lower than in San Pedro or Wilmington, but the harbor air still accelerates seal failure on standard dual-pane glass. We quote both impact and non-impact lines side by side so you can see the price difference and decide with real numbers. Call (888) 635-0804 for both numbers on your opening.
Salt-laden harbor air mixed with diesel soot from the Port of Los Angeles builds up in door tracks and destroys the rollers on original 1960s aluminum sliders within a few years of any repair. In Lomita, that means full-frame replacement is almost always the right call over repairing rollers or track. We can replace the whole unit in one visit and register the warranty before we leave. Call (888) 635-0804 and we’ll quote the replacement, not a patch job.
No, not with us. We write the quote on paper, line by line, and the price you sign is the price you pay. The only exception is if we open a wall and find structural damage that no one could have seen from the outside, and in that case we stop work, show you the problem, and get your written approval before any additional cost. No change orders by surprise, no extra line items at the end.
Yes. Any replacement that changes the opening size or requires Title 24 energy compliance gets permitted through the City of Lomita, and we pull the permit, coordinate the inspection, and stay until it passes. For straightforward insert replacements that match the existing opening, a permit may not be required, and we’ll tell you honestly which situation you’re in before you sign anything. Call (888) 635-0804 to talk through your specific project.

What Lomita Customers Say
"Our bay window had rotted at the sill and two other outfits wanted to talk us into a flat picture window instead. TruePane rebuilt the opening and matched the original look. Neighbors have knocked on the door about it."
- Gene A."Two entry doors. Showed up when they said, second day was a half day like they said, and the painter they recommended confirmed the frames were dead plumb. The financing was explained in actual dollars, not a brochure."
- Janet R."Impact windows on the whole house. They handled the permit, the inspection, and gave me a folder with every approval number for the insurance company. My windstorm premium dropped enough to notice."
- Bill T.
