Windows & Doors Services in Half Moon Bay, CA
If your windows are fogged between the panes, your wood sashes stick every summer, or your patio door grinds on salt-caked track, you already know Half Moon Bay treats a window differently than any inland town. The marine air out here doesn’t just shorten lifespan. It changes how a window has to be specified, installed, and warranted if it’s going to last. TruePane Windows & Doors serves Half Moon Bay homeowners with window and door work built around those conditions. Call (888) 635-0804 and you’ll get a live person, not a tree of voicemail prompts. Most estimates are set within a few days, and we schedule around coastside traffic like people who actually drive Highway 1 every day.

Why Half Moon Bay Homeowners Choose TruePane Windows & Doors
Half Moon Bay residents tend to ask better questions than most. By the time a homeowner here calls us, they’ve usually watched a neighbor’s “bargain” window job fail early, or they’ve scraped corroded hardware off a door themselves. That’s the customer we built TruePane for. Dale Kessler founded this company in 2008 out of a second-generation glazier’s workshop, on a simple rule: if the pane is not true, the job is not done. Every job carries the Done Right Promise and The Keystone Standard, which means both manufacturer warranty layers are registered in writing before the truck leaves your driveway. Durations are stated on paper. No fine print that covers neither.
We’ve set windows throughout the coastal cottages near Miramar Beach and the newer developments east of Highway 1. Our technicians are background-checked and uniformed. They measure every opening twice. They put side-by-side quotes on paper from manufacturers like PGT, CGI, and ES Windows so you see exactly what you’re buying, not a verbal estimate you have to trust. And a live person answers the phone 24 hours a day. If something goes wrong in year two, you won’t be chasing a voicemail box.
Windows & Doors Services We Offer in Half Moon Bay
Window Installation
New construction or retrofit, Half Moon Bay needs window units that can handle wind load and salt exposure without failing at the hardware. We install marine-spec frames and stainless or anodized hardware as a baseline on west-facing elevations, because that’s what the coast demands. Learn more about our Window Installation in Half Moon Bay.

Door Installation
A door on the ocean side of Half Moon Bay takes a beating every day. We install entry doors, hinged and sliding, with weatherstripping and threshold systems that don’t bind when fog moisture swells the jamb. Learn more about our Door Installation in Half Moon Bay.

Window Replacement
If your original single-pane wood windows are pitted, fogged, or rotting at the sill, replacement is often less money long-term than chasing repairs. We quote full-frame and insert options from Andersen, Pella, Marvin, and Milgard so the comparison is in writing. Learn more about our Window Replacement in Half Moon Bay.

Impact Windows & Doors
High-wind exposure along the bluffs and near Pillar Point puts real stress on frames and glass. Impact Windows & Doors in Half Moon Bay from PGT and CGI carry design pressure ratings that standard windows don’t, and we install them to manufacturer spec so the rating holds.

Energy-Efficient Windows
Half Moon Bay doesn’t get inland heat, but the persistent summer marine layer still drives heating costs and interior moisture. Energy-Efficient Windows in Half Moon Bay with Low-E glass and proper glazing reduce condensation on cool foggy mornings and keep indoor temperatures stable year-round.

Sliding & Patio Doors
Salt and airborne sand collect in door tracks and rollers. We install Sliding & Patio Doors in Half Moon Bay with marine-grade rollers and tracks, then set the adjustment so the door glides instead of grinding.

Glass Railing Systems
Coastside decks and bluff-side homes often call for glass railing that doesn’t block the view. We install Glass Railing Systems in Half Moon Bay with tempered glass and stainless standoffs rated for continuous salt-air exposure, not interior hardware that pits in two years.

Custom Windows & Doors
Older bungalows in Half Moon Bay rarely have standard rough openings. We order and install fully custom window and door units sized to the actual opening, which usually saves you the cost of reframing.

Why Half Moon Bay’s Climate & Housing Affect Windows & Doors
Half Moon Bay sits directly on the open Pacific. There’s no significant geographic buffer, no inland heat to burn off the fog. What that means for your windows and doors is not abstract. Salt-laden marine air deposits on hardware and tracks year-round. The near-daily fog keeps wood sills damp enough to feed rot. Prevailing northwest onshore winds push moisture against west-facing frames for months at a time. On properties near the bluffs and Miramar Beach, builder-grade powder-coated aluminum window frames routinely show visible oxidation and pitting within three to five years. That’s not a failure your contractor can wax over. It’s a material problem, and it’s why we default to fiberglass or marine-anodized aluminum on that side of town, plus stainless or anodized hardware as a standard specification, not an upcharge conversation.
The housing stock makes it worse in specific ways. Older beach cottages from the mid-20th century still carry original single-pane wood windows. Those sashes swell and stick seasonally as the humidity cycles. Glazing seals fail. Sills rot. Meanwhile, the newer developments built east of Highway 1 in the 1980s and 1990s used aluminum frames that are now at the end of their service life. Either way, when TruePane works in Half Moon Bay, we’re not installing a generic window and hoping. We’re matching the unit to the elevation, the exposure, and the home’s specific moisture behavior.
Pricing for Windows & Doors in Half Moon Bay
Honest numbers, because you asked and because nobody gives you straight answers in this market. Entry-level vinyl window replacement runs roughly $500 to $850 per window installed.

FAQs About Windows & Doors in Half Moon Bay
Window replacement in Half Moon Bay typically runs $500 to $1,400 per window installed, with premium lines reaching $2,200 or more, and impact-rated glass running 30 to 50 percent above standard glass. Every quote we write is fixed and line-item, with warranty durations stated in writing. Call (888) 635-0804 for an exact number on your windows. Estimates are free.
Fogged glass means the seal on your insulated glass unit has failed, and in Half Moon Bay the constant marine humidity accelerates that failure. Once the seal is broken, moisture collects between the panes and the unit loses its insulating value. The fix is replacement of the glass unit or the entire sash, not a surface repair. We can order the correct spec from the manufacturer and have it set fast.
It depends on your elevation and your tolerance for risk. Homes near the bluffs, Pillar Point, and directly exposed ocean-facing elevations see the highest wind loads. Impact-rated windows from PGT or CGI carry design pressure ratings that standard units don’t meet. We’ll quote both options side by side with the pressure ratings stated, and let you decide with real numbers in front of you.
No. On our fixed-price quotes, the number we hand you is the number you pay. If we find unforeseen damage after opening a wall or removing an old unit, we stop and show you what we found before we do any additional work. No change orders appear out of nowhere. Call (888) 635-0804 and we’ll put that in writing on your quote.
Most standard window replacements are completed in one to two days once the units arrive from the manufacturer. Custom or impact-rated orders take longer because the units are built to spec, not pulled from warehouse stock. We’ll give you a written timeline on the estimate, and we’ll be there when we say.

What Half Moon Bay Customers Say
"Whole-house window replacement at 71 years old is not something you want to do twice. Dale walked the house himself for the quote. Crew was the same three men all four days, and the foreman knew every window by room."
- Pat and Ray L."Eleven windows replaced in two days. The crew chief, Marcus, showed me the level on every single frame before they caulked it. My wife noticed the street noise was gone before I did."
- Ronald P."A casement crank had stripped and the sash was swollen shut. The technician, Ray, fixed the crank on the spot and only then talked about replacement for the three windows that were genuinely done. That is why the whole street uses them now."
- Eleanor G.
