AfterFast, Reliable Windows & Doors Across Costa Mesa
If you own a home in Costa Mesa built between the 1950s and 1970s, there’s a good chance your windows and doors have outlived their useful life, and the marine-layer humidity that rolls through town from May through August hasn’t done the frames any favors. Barrett & Sons Construction handles window and door replacement across Costa Mesa from start to finish: permits pulled, written change orders only, and no surprise line items at the end. We’re the outfit where Tom Barrett’s name is on the truck and his sons run the crews, and you can reach a live person at (877) 610-1318 whenever you need us.
Why Barrett & Sons Construction Is Costa Mesa’s Preferred Windows & Doors Company
We’ve spent years working inside Costa Mesa’s Eastside tract homes, and it’s taught us what a real window or door project looks like long before the first nail moves. Those 1950s and 1960s wood-frame ranches are honest houses with good bones, but their window openings, door headers, and flashing details were built to a code that no longer applies, and Costa Mesa’s coastal humidity has been working against them for 60 years. We know which Eastside blocks lean toward original single-pane sliders and which canyon-adjacent properties need impact-rated glass, and that local knowledge translates into quotes that hold up once the walls are open.
Tom Barrett founded this company in 1998, and the people showing up to your Costa Mesa home are his sons and their background-checked crews, not a rotating cast of subcontractors. Every scope change, allowance, and price adjustment arrives as a written change order before we pick up a tool. The permit inspector works for you, not for us, and that’s why we like having them involved. If a window replacement in your Eastside home uncovers a sagging header or rotted framing behind the stucco, we don’t bury it in a surprise invoice. We document it, put it in writing, and you decide before we spend another dollar.
Call (877) 610-1318 and the person who answers is someone who knows Costa Mesa permitting, not a call center reading a script. The 90-Day Done Right Promise is written on every contract: if it isn’t done right, one call brings Tom back to make it right.
Our Windows & Doors Services in Costa Mesa
Most Costa Mesa homes we work on fall into one of a few repair or replacement categories, and the scope usually expands once we get eyes on the framing behind the old window or door. Here’s how we approach the jobs we see the most across the 92626, 92627, and 92628 zip codes:
Window Replacement
Window replacement in Costa Mesa typically runs $4,500 to $15,000 depending on the number of openings and whether we’re matching existing stucco openings on an Eastside ranch or re-framing entirely. The older the house, the more likely the original window headers are undersized by current code, and a permit pulls that into the open. We spec dual-pane glass, pressure-treated lumber for new frames where rot is found, and flashing details that hold up to Costa Mesa’s morning marine layer. The work doesn’t get done twice because of overlooked waterproofing.
Door Installation
A new front door in Costa Mesa isn’t just a panel swap. The original 1960s framing around many Eastside entryways has settled, and the threshold flashing was often installed directly against raw lumber with no membrane. We re-frame where needed, level the rough opening, and install doors that seal against the humidity and stay square. Sliders and French doors get special attention because that’s where we see the most water intrusion months after a job should have been done right.
Impact Windows & Doors
Impact window installation in Costa Mesa runs $8,000 to $25,000 depending on the opening sizes and the product line, and it’s not just about storm safety. Impact-rated glass also handles the heat gain and glare from Costa Mesa’s long, sunny days, and it carries a sound-dampening benefit on busy streets east of Newport Boulevard. We install Simonton and PGT impact lines and verify every opening against current code before the permit application goes in.
Sliding & Patio Doors
Sliding and patio door replacement in Costa Mesa typically lands between $3,000 and $7,500, with variance driven by whether we’re swapping a standard 6-foot slider or re-framing a wall for wider glass. On Eastside lots where the original ranchers were built with tiny patio sliders, we often widen the opening to capture backyard light without shrinking the usable wall space. The key detail is the pan flashing at the base. Skip it in Costa Mesa and the first winter rain finds its way inside.

Trusted Brands We Service in Costa Mesa
We install and service premium window and door lines you can look up by name: Simonton, Ply Gem, and PGT are the most common products we put into Costa Mesa homes. There’s a reason we don’t show up with mystery brands off the back of a van. When a PGT impact window fails under warranty or a Simonton slider needs a new roller assembly, we can get parts ordered and the job scheduled without telling you your best option is a full replacement. If you already have Andersen or Marvin products, our Windows & Doors team handles those service calls as well.
Common Windows & Doors Problems We See in Costa Mesa Homes
Costa Mesa’s climate and housing stock create a predictable set of failure points, and most of them are behind the wall where you can’t see them until the opening is exposed. Here’s what we regularly find:
- Marine-layer rot at window and door sills. The May-through-August morning humidity in Costa Mesa moves through unventilated crawl spaces and soaks into unpainted end grain. Original 1950s frames often crumble at the sill before the glass shows any signs of failure.
- Undersized 1960s headers over window and door openings. Once a permit is pulled, the inspector checks the header against current code. We’ve opened Eastside walls and found headers sagging 3/4 inch, which means replacement with an engineered beam before we can set the new window.
- Failed waterproofing membrane behind stucco. A lot of Costa Mesa’s original stucco work went directly over felt paper with no drainage plane. When we pull an old window, we often find no waterproofing at all, and the new flashing has to be built from scratch.
- Improper flashing on ADU and garage-conversion windows and doors. Costa Mesa’s ADU-permitting pipeline has driven a wave of two-story ADUs and garage conversions on Eastside lots where setbacks are tight, and rushed flashing where new window and door frames meet existing stucco leads to water intrusion that shows up months after sign-off.
Pricing for Windows & Doors in Costa Mesa, CA
Honest pricing for window and door work in Costa Mesa breaks down into line items you can verify before signing. The ranges below reflect what we actually charge across the city’s housing stock, from Eastside originals to newer homes west of the 405:
| Project | Typical Costa Mesa Range |
|---|---|
| Window Replacement | $4,500 - $15,000 |
| Impact Window Installation | $8,000 - $25,000 |
| Sliding & Patio Doors | $3,000 - $7,500 |
What moves a quote within those ranges is mostly what we find after the opening is exposed: undersized headers, rotted king studs, failed waterproofing. That’s why we write allowances into the contract before we start. If an allowance isn’t on paper, it’s a surprise waiting for a date. Call (877) 610-1318 for a written line-item estimate, and we’ll walk the openings with you before we quote anything. Estimates are free, and there’s no trip charge inside Orange County.

FAQs - Windows & Doors in Costa Mesa
Opening an exterior wall on a 1950s or 1960s Costa Mesa home triggers current building code for the structural work we touch, and the two most common upgrades are header replacement and waterproofing. If the original header is undersized for the span, the inspector requires an engineered beam, and if the original stucco has no drainage membrane, we need to build one before closing the wall. We write these possibilities into the contract as allowances so the quote moves in writing, not at the end of the job. Call (877) 610-1318 and we’ll walk through what your specific openings will likely require.
Costa Mesa sits close enough to the Pacific that marine-layer humidity cycles through most mornings from May through August, and those wet, cool cycles soak into exposed end grain and unventilated crawl spaces in a way that Anaheim or Orange never sees. Add 60 years of that exposure to original single-pane frames, and the sill rots before the glass ever fails. We pull rotted framing and replace it with pressure-treated lumber, and we check the crawl space ventilation on every job.
Impact windows don’t change setback rules in Costa Mesa, but they can change the design conversation. On Eastside lots where the ADU sits tight against the property line, large openings need glazing that meets current safety and energy code, and impact-rated products often satisfy both while letting in more light than a smaller standard window. We spec PGT and Simonton impact lines on two-story ADU designs where maximum glass matters and the inspection requires documented ratings.
Expect the quote to include a written allowance for header replacement, not a vague line that says “as needed.” We know from working Eastside ranches that a header under today’s code often requires an engineered beam, and the allowance should cover the beam, re-framing, and the inspection. Any adjustment gets written as a change order before we spend it. Call (877) 610-1318 for an exact quote after we see the opening.
We show the inspector the failed waterproofing, we document it, and we build the new flashing and drainage plane to current code before the wall is closed. That means the inspection passes with the work visible, not hidden behind stucco. Costa Mesa’s Building Division is used to seeing failed waterproofing on Eastside homes; it doesn’t stall the job, it just gets done correctly and signed off. We pull permits and pass inspections on every eligible Costa Mesa window and door job.
One More Thing About Eastside Homes
Costa Mesa’s Eastside, the 92627 zip code, is its own animal when it comes to window and door work. Rows of 1950s and 1960s wood-frame tract homes sit on modest 5,000 to 7,500 square foot lots just across the line from Newport Beach, and the city’s ADU-permitting pipeline is pushing two-story ADUs and garage conversions at a pace you won’t find in neighboring beach cities. That means window and door specs are repeatedly tied to setback-driven design: how much glass you can fit on a wall five feet from the lot line, what impact and energy codes apply, and whether the original header can carry a wider opening. It’s a very Costa Mesa problem. We solve it with pre-open inspections, written allowances, and products like PGT impact windows that meet the documentation the city wants to see. A couple of years back, on a 1950s ranch off Newport Boulevard, our crew opened a wall to replace a rotted single-pane window and found the original galvanized supply lines degrading, a load-bearing header sagging 3/4 inch, and no waterproofing membrane behind the stucco at all. We documented everything, wrote the code-triggered upgrades into the change order, replaced the window with a dual-pane unit framed with pressure-treated lumber, and sign-off passed that same week. That’s the Costa Mesa job we’ve done many times over.
