Fast, Reliable Windows & Doors Across Los Alamitos
When a window seal fails or a door frame starts sagging in Los Alamitos, you’re usually dealing with a house built between the late 1940s and mid-1970s. Most of these tract homes on slab foundations have original aluminum frames that leak conditioned air and rattle when military planes climb out of JFTB Los Alamitos. Window replacement in Los Alamitos typically runs $4,500 to $15,000 for a full home, and impact window installation starts around $8,000 depending on how many openings you have. We know this housing stock because our crews work these streets every week, from 90720 to 90721. Call (877) 610-1318 and Tom or one of his sons will come out, measure every opening, and give you a written line-item quote before anything moves.
We’re Barrett & Sons Construction, and our Windows & Doors team has spent nearly three decades replacing and installing windows and doors in Orange County’s older post-war neighborhoods. Los Alamitos is different from Cypress or Seal Beach. The homes are smaller, the setbacks are tighter, and the marine layer keeps sill plates damp longer than most people realize. You need someone who knows what’s behind the stucco before they cut into it.
Why Barrett & Sons Construction Is Los Alamitos’s Preferred Windows & Doors Company
Tom Barrett founded this company in 1998 and put his name on the truck. His sons run the crews now. When you call about windows and doors in Los Alamitos, you’re not getting a call center in another state. A live person answers 24 hours a day, and the person who shows up to measure is the same person who works on your house.
We publish our license number, our address, and Tom’s name. Before you sign anything, look us up. That transparency is rare in this trade, and Los Alamitos homeowners who’ve dealt with national outfits that quote one number on the phone and deliver another at the door tend to appreciate it. Every change order on your Los Alamitos job arrives in writing before work starts. Not after.
Our crews are background-checked, uniformed, and carry the Barrett & Sons name on every visit. We pull permits on every eligible job because the permit inspector works for you, not for us. We like it that way.
Our Windows & Doors Services in Los Alamitos
Window Installation
Los Alamitos Kitchen Remodeling aside, new window installation on a 1958 rancher in Los Alamitos usually means retrofitting existing openings rather than cutting new ones. That’s typical for 90720 and 90721 homes. We measure, order, and install Andersen and Marvin frames, then flash and seal everything to handle morning marine-layer moisture that lingers on west-facing walls. You’ll see the difference on your energy bill within a full season.

Door Installation
Front doors in these tract homes tend to be narrow by modern standards. We regularly widen rough openings, reframe the header, and hang a properly sized door that doesn’t scrape or bind when the slab settles. Los Alamitos sits on soft coastal-plain soils, so we account for slight foundation movement rather than pretending it doesn’t exist. Exterior door installation typically runs $2,000 to $6,500 here depending on size and material.

Window Replacement
Most Los Alamitos homes built between 1950 and 1975 still have single-pane aluminum windows. In summer, those frames conduct heat into the house. In winter, they fog up from the marine layer. Full window replacement in Los Alamitos runs $4,500 to $15,000 for an average single-story home. We’ll give you the exact number in writing before you commit to anything.

Impact Windows & Doors
You don’t have to live in Florida to want impact-rated glass. Los Alamitos sits in a seismic zone, and older single-pane windows are a hazard in an earthquake. Impact window installation in Los Alamitos runs $8,000 to $25,000 depending on the number of openings. These units also cut down noise from JFTB air operations and Cerritos Avenue traffic during rush hour. We’ll show you samples and explain the ratings before you decide.

Sliding & Patio Doors
Mid-century Los Alamitos homes often have original aluminum sliders that have been sticking for twenty years. We replace the track, the rollers, and the frame when needed, or install a new multi-slide unit if the old one is beyond saving. Patio door replacement in this area typically runs $2,500 to $7,000. We also install glass railing systems for raised patios and balconies on Home Additions & ADU in Los Alamitos.

Custom Windows & Doors
Some Los Alamitos homeowners want a specific look: arched tops, divided lites, or custom heights for a dining room bump-out. We handle built-to-order windows and doors, including impact sliding glass doors and hurricane-rated units. If you’re planning an addition or ADU on one of these compact lots, we can match the new openings to your existing architecture. You’re also welcome to ask us about Fence Installation in Los Alamitos, since a lot of window and door projects turn into perimeter work once the house is opened up.

Trusted Brands We Service in Los Alamitos
We install Andersen and Marvin windows and doors because those are brands you can look up, not mystery units off a van. We also work with Techo-Bloc and Cambridge Pavers when a project includes a patio or entry landing that ties into the door installation. Our crews stock common hardware, weatherstripping, and track components for Los Alamitos homes, so a rotted sill or broken latch doesn’t have to wait a week for parts. If your project includes a walkway or entry pad replacement, ask about our Driveway & Pavers in Los Alamitos work too.
Common Windows & Doors Problems We See in Los Alamitos Homes
- Rotted sill plates from persistent marine-layer moisture. West-facing walls in 90720 stay damp longer than inland areas. We replace the sill and flash the opening correctly so it doesn’t happen again in five years.
- Original aluminum sliders that no longer lock or seal. Many of these are fifty to seventy years old. The latch mechanisms are discontinued, and the tracks are worn past repair. Replacement is usually the only honest fix.
- Foundation movement causing doors to bind. The soft alluvial soils under Los Alamitos settle unevenly. A door that rubs at the top corner in summer may swing fine in winter. We shim and rehang doors with settlement in mind.
- Single-pane windows that rattle during JFTB air operations. Military aircraft departing KSLI produce low-frequency noise that standard windows don’t block. Impact-rated glass and proper weatherstripping make a real difference.

Many window and door replacements that don’t change the rough opening can be done without a permit, but we pull one whenever the scope triggers it: new openings, widened rough openings, structural headers, or impact-rated installations. We’d rather have the inspector sign off than leave you with unpermitted work that causes problems when you sell.
Window and door pricing in Los Alamitos is generally in line with the rest of northwestern Orange County. You might pay slightly more for impact-rated glass and seismic detailing than you would in a city without JFTB air traffic overhead, but the labor and material costs are comparable. We’ll show you the exact numbers for your house, not a vague range.
