AfterFast, Reliable Windows & Doors Across Redwood City
Window and door replacement in Redwood City runs anywhere from $4,500 for a basic retrofit to $25,000 or more for full impact-rated systems, and the ground under your house has a lot to say about the final number. We’re Barrett & Sons Construction, and we’ve been replacing windows and hanging doors across the Peninsula long enough to know that a 1960s ranch near Roosevelt and a 1980s townhome in Redwood Shores are two completely different jobs. If you’re seeing fogged glass, sticking sliders, or drafts you can feel from across the room, call (877) 610-1318 and we’ll come take a look. The estimate is free, and we’ll tell you straight what needs doing and what can wait.
Why Barrett & Sons Construction Is Redwood City’s Preferred Windows & Doors Company
Tom Barrett has had his name on the truck since 1998, and his sons run the crews that work in Redwood City. That matters to homeowners here because the Windows & Doors trade on the Peninsula is full of outfits that quote one number on the phone and hand you a different one after the trim comes off. We don’t do that. Every scope item, every allowance, every price change arrives as a written change order before work proceeds, not after. If it’s not in writing, it doesn’t exist.
Our Redwood City customers call the same local number and reach a live person, 24 hours a day, seven days a week. Not a voicemail box, not an out-of-state call center. Tom publishes his name, his address, and his license number, and he expects you to look them up. Ask anyone on your street, or check the license yourself. We stand behind every install with the 90-Day Done Right Promise, written on the contract: if it isn’t done right, Tom comes back and makes it right, one call.
Much of our work in Redwood City comes from referrals. The neighbor who watched us replace a full wall of windows on Redwood Shores Parkway tells the neighbor on Brewster Avenue. That’s how it should work. We pull permits on every eligible job because the permit inspector works for you, not for us, and that’s exactly why we like him.
Our Windows & Doors Services in Redwood City
Window Replacement
Most of the flatland homes in Redwood City’s 94063 and 94061 ZIP codes were built in the 1940s through 1960s. Original wood sash windows are usually past saving, and the aluminum replacements from the 1980s are often corroded at the corners. A typical full-house window replacement in Redwood City runs $4,500 to $15,000. We replace with Andersen and Marvin units when the budget allows, and we verify the rough openings before we order anything.
Door Installation
Entry doors in Redwood City take abuse from sun and, in the Shores, salt air. We install pre-hung exterior doors, storm doors, and interior passage doors, and we check the existing framing for square before the new door goes in. A door hung in a settled opening will bind within a year. We’d rather correct the opening now than come back and do it over.
Sliding & Patio Doors
Sliding patio doors in Redwood Shores townhomes fail in specific, predictable ways. The bay mud under 94065 settles unevenly, the slab twists, and the slider binds on the high side. Weatherstripping shreds within a season. We level the track, replace worn rollers, and when the frame is out of plane beyond adjustment, we rebuild the rough opening before installing the new door. No amount of silicone fixes a slab that has moved.
Impact Windows & Doors
Bay-facing properties in Redwood Shores get persistent salt-laden wind off the water. Impact-rated windows and doors, $8,000 to $25,000 depending on count and size, resist wind-driven debris and protect against the corrosion that eats standard aluminum frames from the weep holes inward. These are not a legal requirement in Redwood City the way they are in South Florida, but for shorefront homeowners they are the difference between a ten-year window and a forty-year window.

Common Windows & Doors Problems We See in Redwood City Homes
- Salt-corroded flashing and anchors on bay-facing windows in Redwood Shores. Weephole corrosion lets water behind stucco returns, and by the time you see the stain on the interior drywall, the rough framing behind it has been rotting for years. We cut back the stucco, replace the damaged framing, and reflash with proper sill pans before the new window goes in.
- Settling slabs in 94065 that twist door frames out of square. Sliders bind, French doors won’t latch, and weatherstripping wears out in a single season. This is a foundation problem presenting as a door problem. We diagnose it correctly before you spend money on a door that won’t fix it.
- Undersized headers found when enlarging window openings in 1940s and 1960s ranch homes. Those post-war houses on the flatlands were built fast, and the headers over original windows are often barely adequate for the original opening. Enlarge the opening and you have to upgrade the header. We plan for that from the first inspection, so the permit and the price account for it.
- Fogged double-pane units in original aluminum frames. The seals fail, condensation forms between the panes, and the glass gets a permanent film you can’t clean. Replacement glass alone doesn’t fix a corroded frame. We replace the whole unit when the frame is compromised.
Pricing for Windows & Doors in Redwood City, CA
Window and door pricing in Redwood City tracks the age and condition of the house, not just the size of the window. A simple vinyl retrofit into a square opening costs far less than an impact-rated replacement in a house where the slab has settled an inch. Here’s where the market lands:
| Service | Typical Range in Redwood City |
|---|---|
| Window Replacement | $4,500-$15,000 |
| Impact Window Installation | $8,000-$25,000 |
Those ranges cover a typical Redwood City home. Bay-facing homes in the Shores trend toward the upper end because of the corrosion work and framing corrections. Call (877) 610-1318 and we’ll give you a written, line-item quote before any money changes hands. The estimate is free, and the price on the quote is the price you pay unless a written change order says otherwise.
How Redwood Shores Geology Affects Window and Door Work
Redwood City is split between two worlds, geologically speaking. The flatland neighborhoods east of El Camino Real sit on natural Peninsula soil, the same stable ground you’d find in San Carlos or Menlo Park. Redwood Shores, ZIP 94065, sits on filled bay mud, and everything built there since the 1970s is sitting on compressible material that continues to settle. This is not a subtle detail. Slabs poured in the 1980s on the original fill have frequently gone out of plane by an inch or more. A window contractor who doesn’t check for that before ordering frames will install new windows into twisted openings, and the homeowner will be fighting sashes, locks, and condensation for as long as they own the house.
Before we order a single frame for a Redwood Shores job, we check the slab. If the floor has settled unevenly, new windows and doors can’t sit square until the subfloor is corrected. That conversation happens before the quote is final, not after the old windows are out. This split geology changes what a window and door contractor must inspect and plan for across Redwood City, and it’s the first thing we look at on any job east of the freeway versus west of the water.
Trusted Brands We Service in Redwood City
We carry Andersen and Marvin windows because we’ve seen how they hold up in Redwood City’s sun and, in the Shores, salt air. For door thresholds and waterproofing membranes we use Schluter and GAF products, which hold up under bayfront conditions better than the alternatives. We keep common components in stock for these brands, so a replacement part doesn’t strand a Redwood City homeowner for weeks waiting on a distributor. If you know the brand you want, tell us and we’ll quote it. If you don’t, we’ll tell you what holds up in your neighborhood.
A Job We Ran in Redwood Shores
We recently replaced a full set of aluminum windows and a sliding patio door in a 1970s Redwood Shores townhome near Marine Parkway. The original frames had corroded where salt air worked into the weep holes, and once we pulled the trim, the rough openings were no longer square. The slab had settled almost an inch on the bay-side corner. We sistered the framing, scribed the new sill pans to the high side, and got inspection sign-off before we ever hung the new Andersen 100-series units. That’s what a Redwood Shores window job actually looks like when someone checks the ground before they check the glass.

FAQs - Windows & Doors in Redwood City
Yes, if the house sits on the original bay-mud fill. Slabs in 94065 have settled unevenly in many cases, and new frames installed into out-of-plane openings will bind and leak. We check the slab before quoting any Redwood Shores window job. If the settlement is minor, we can often shim and flash around it. If it’s structural, that gets corrected first. Call (877) 610-1318 and we’ll tell you which category your house falls into.
In most cases, yes. Retrofit replacement windows slide into the existing frame after the old sashes and tracks are removed, leaving the surrounding stucco intact. The exception is when the original frame has water damage or corrosion behind the stucco return, which requires cutting back the stucco to repair the framing. We inspect for that before we quote. Call (877) 610-1318 and we’ll take a look for free.
Differential settlement of the slab under bay mud fill. The slab drops unevenly, the door frame twists out of square, and the rollers bind on the low side. Replacing the rollers helps temporarily, but the door will bind again unless the opening is corrected. We level what we can and rebuild the rough opening when we can’t. Call (877) 610-1318 for a diagnosis.
Yes, and you should want one. Enlarging a window opening means modifying the exterior wall, which brings the work under Redwood City’s building code, and on older ranch homes it usually means upgrading the header over the new opening. We pull permits on every eligible job, and the permit inspector works for you, not for us. Anyone who tells you permits are optional is telling you something about themselves. Call (877) 610-1318 and we’ll handle it correctly.
Salt-laden air off the Bay works into the weep holes and corrodes the aluminum frame from the inside out. Condensation forms where the warm interior air meets the cold metal, and the corrosion accelerates. Once the frame starts to go, the glass seal usually follows. Impact-rated replacement windows with proper thermal breaks stop the cycle. Call (877) 610-1318 for a quote on replacements that will actually hold up on the water side.
