AfterFast, Reliable Windows & Doors Across Half Moon Bay
Window and door replacement in Half Moon Bay isn’t the same job it is over the hill in San Mateo or Redwood City. The salt air, the fog that sits on your house for weeks at a time, and the Coastal Commission’s review process all shape what needs to happen when you pull an old frame out of a 1956 ranch off Highway 92. We’ve been doing exactly that work since 1998, and Tom Barrett’s sons run the crews you’ll see on your job. Call (877) 610-1318 for a free estimate, and we’ll walk you through what your specific house actually needs before any number goes on paper.
Why Barrett & Sons Construction Is Half Moon Bay’s Preferred Windows & Doors Company
Tom Barrett publishes his name, his address, and his license number. Look us up before you sign anything. That’s the first thing that separates us from the out-of-area outfits who quote one price over the phone and show up with a different one after the wall is open. Our crew members are background-checked and uniformed on every visit, and they carry the Barrett & Sons name because they’ve earned it over years, not a seasonal hiring push.
Half Moon Bay homeowners call us because we answer the phone. Not a voicemail box, not an out-of-state call center. A live person, 24/7. When you’ve got fog drip pooling at a rotted sill plate and the old window is already out, you need someone who picks up. We also know the Coastal Commission’s San Francisco District office process cold, which matters more in 94019 than any marketing brochure will tell you.
Every job gets permits pulled and inspections signed when eligible, and every price change arrives as a written change order before work proceeds. An allowance that isn’t on paper is a surprise waiting for a date. We don’t do surprises.
Our Windows & Doors Services in Half Moon Bay
Our Windows & Doors team handles the full scope of exterior opening work across Half Moon Bay. Here’s what that looks like on the ground.
Window Replacement
Most Half Moon Bay homes we open up fall into one of three camps: early-1900s cottages in Old Town, mid-century ranch homes along the Highway 92 corridor, or newer coastal builds near Miramar. The older the house, the higher the odds we find rot in the sill plate or sheathing once the old window comes out. We scope for that up front, write a remediation allowance into the contract, and if we find something worse, you get a written change order before we touch the opening. No one in Half Moon Bay should be surprised by structural framing costs on window day.
Door Installation
Entry doors, French doors, and side lights all face the same salt-laden wind off the Pacific. We use stainless or hot-dipped galvanized fasteners as a baseline on exterior door work here, not as an upgrade. The fog belt along the coastal cypress keeps rooflines and foundation perimeters wet even when it hasn’t rained in weeks, so flashing details get the same attention as the door itself. A door that seals but rots around the jamb in four years isn’t a door job done right.
Impact Windows & Doors
Half Moon Bay sits in a high-wind coastal zone, and while impact ratings aren’t mandatory for every home the way they might be in Florida or the Gulf, many homeowners here choose them for storm season and insurance reasons. Impact windows and doors in Half Moon Bay typically run $8,000 to $25,000 depending on opening count and glass pack. The Coastal Commission reviews most exterior changes on these jobs, so we file early and build the permit timeline into the schedule from day one.
Custom Windows & Doors
Older Half Moon Bay homes rarely have standard rough openings. The cottage on Kelly Avenue that’s been added onto three times since 1948 doesn’t fit a stock Andersen double-hung. We template every opening, order custom-sized units, and work with the Coastal Commission’s setback and visual review requirements when a custom window changes exterior dimensions or glass area. You get windows that fit the house, not a house that gets modified to fit a window off the rack.

Trusted Brands We Service in Half Moon Bay
We install Andersen and Marvin windows and doors because they’re brands you can look up, not mystery units off a van. For homes in the Miramar and Princeton-by-the-Sea areas where salt exposure is worst, we often recommend stainless hardware packages and factory-applied coastal finishes from those manufacturers. We don’t stock parts for brands we don’t trust, and we don’t expect Half Moon Bay homeowners to trust a name we wouldn’t put on our own houses.
Common Windows & Doors Problems We See in Half Moon Bay Homes
- Salt-air rot in sill plates and sheathing. We open a lot of 1950s-70s ranches off Highway 92 where the framing around windows and doors has been quietly wicking moisture for decades. The old window works fine; the wood holding it doesn’t. We find it, price it, and get written approval before we fix it.
- Coastal Development Permit tripwires. A window swap that changes glass area or exterior dimensions can trigger full Coastal Commission review on top of city permits. Out-of-area GCs miss this and the project freezes mid-construction. We file first, not after the opening is cut.
- Corroded flashing and fasteners. Thirty years of salt-laden fog eats through standard galvanized flashing. When we pull an old door or window on the ocean side of a Miramar home, we routinely find fasteners that snap rather than turn. Stainless or hot-dipped hardware is the baseline on our jobs here.
- Fog-driven condensation and water damage around wall openings. The marine layer keeps humidity high even in summer. Poorly flashed windows from 1960s construction wick that moisture into the wall cavity. By the time you see paint bubbling inside, the sheathing behind it is usually gone.

FAQs - Windows & Doors in Half Moon Bay
Yes, in many cases. Nearly every developed area of Half Moon Bay falls within the California Coastal Commission’s coastal zone. If your window replacement changes exterior dimensions, glass area, or certain frame materials, you’ll need a Coastal Development Permit from the Commission’s San Francisco District office on top of the standard city permit. An interior-only like-for-like swap may qualify as exempt, but we review the specifics before you commit to any scope. Call (877) 610-1318 and we’ll tell you what your address actually triggers.
Because decades of salt-laden fog and marine-layer moisture have been working on the framing behind the old unit. Half Moon Bay’s persistent humidity keeps wood damp year-round, and salt accelerates the breakdown. Homes from the 1950s-70s along Highway 92 are the most common place we find sill plates that have lost their structural integrity. We budget for this up front with a written remediation allowance.
Not entirely, but it can be planned for. We write allowances for hidden structural repair into every Half Moon Bay window contract because we know from experience what’s behind these walls. When we find something beyond the allowance, you get a written change order with pricing before we do the extra work. What you don’t get is a surprise invoice at the end. The permit timeline we also build in from day one, so a Coastal Commission review doesn’t stall the job mid-opening.
No, Half Moon Bay building code doesn’t mandate impact-rated windows the way some hurricane zones do. But many coastal homeowners here choose them anyway for storm season protection and potential insurance benefits. If you’re in an exposed area near Miramar or Princeton-by-the-Sea, we can walk you through whether impact glazing is worth the cost on your specific house.
We file the Coastal Development Permit application with the San Francisco District office before we open the wall. The application includes your site plan, elevations, and details on the proposed window or door changes. We handle the submittal, the revisions, and the timeline so the permit decision arrives before the old unit is scheduled to come out. You don’t chase paperwork. Call (877) 610-1318 for an exact quote on your project, estimates are free.
