Fast, Reliable Custom Windows & Doors Across Seaside
Custom window and door work in Seaside usually means one of two things: replacing corroded aluminum jalousies in a 1950s Fort Ord duplex, or shaping a window to fit a view of Monterey Bay that a standard size was never built for. Both jobs demand the same thing from an installer: marine-grade materials specified from the start, and a crew that knows what fifty years of salt fog does to a frame. We do both. TruePane Windows & Doors serves the 93955 ZIP with custom design, full-system replacement, and in-home estimates. Call (888) 635-0804 to schedule yours.
Why TruePane Windows & Doors Is Seaside’s Preferred Custom Windows & Doors Company
We have spent years working inside Seaside’s particular housing stock: the 1940s tract homes off Hilby Avenue, the duplex rows near Noche Buena Street, the older rentals around Fremont Boulevard that still have their original louvered glass. That local repetition teaches a contractor things that a drive-in crew from Salinas or San Jose will miss. It teaches you, for example, that a jalousie in Seaside does not get weathersealed, it gets replaced, because the salt air has already eaten the frame the slats sit in. It teaches you that wood sills on the west-facing side of a house need marine-grade flashing tape, not whatever was on the truck.
Customers in Seaside tell us the same thing in different ways. They want a company that answers the phone when the fog rolls in and the door that worked in October decides June is its month to bind. They want a live person, not a callback form. That is how we have run things since 2008 across the broader community, led by second-generation glazier Dale Kessler, and it is how we run jobs in Seaside today. Our estimate is free. Our pricing is written down before we start the work, not revised after.
Our Custom Windows & Doors Services in Seaside
Custom Shape Windows
Seaside has more than its share of half-rounds, trapezoids, angle-tops, and picture windows that were framed to catch a specific slice of light off the bay. When one of those fails after decades of salt exposure, there is no off-the-shelf replacement. We cut and build custom units that match the original rough opening, then set them in marine-grade frames that will not repeat the old failure. A custom shape window in Seaside typically runs $900 to $2,600 installed, depending on glass size, frame material, and whether we are reframing an opening that has rotted.

Architectural Grilles & SDLs
Grilles and simulated divided lites change the whole character of a window, and on Seaside’s older homes, they are often the cheapest way to bring a replacement window visually back in line with the original 1950s or 1960s design. We install SDLs inside the glass cavity and true divided lites where the home calls for them. In a tract house off San Pablo Avenue, a simple colonial grille pattern can cost $150 to $450 per window. In a custom home facing the water, a true divided lite set can run $600 to $1,400 per unit. The workmanship is warrantied either way.

Oversized Glass Panels
Seaside’s fog layer sits low and heavy for much of the year, but when it lifts, the view from the higher streets near the old Fort Ord boundary is worth building around. Oversized glass panels let homeowners capture that without a grid of mullions breaking the sightline. We install large-format units up to the structural limits of the wall they sit in, using reinforced framing and laminated glass where wind load from the bay requires it. An oversized fixed panel in Seaside generally starts around $1,800 and can run past $6,000 for floor-to-ceiling tempered glass with a marine-grade frame.

Commercial Storefront Glazing & Curtain Wall Systems
Seaside’s commercial corridors, Fremont Boulevard and Del Monte Boulevard among them, include storefronts that date to the same mid-century period as the housing. Salt air does not discriminate between a picture window and a storefront. We replace failed storefront glazing, rebuild aluminum entries, and spec curtain wall systems with the same coastal-grade fasteners and seals we use on residential work. For a small storefront in Seaside, a storefront glazing replacement typically costs $3,500 to $12,000 depending on lineal footage and whether the framing itself can be salvaged. A full curtain wall system runs higher, often $150 to $300 per linear foot of glazing installed, and we provide a written line-item quote before any work begins.

Trusted Brands We Service in Seaside
We are an authorized installer for more than a dozen manufacturer lines, and in Seaside we most often spec PGT, CGI, and ES Windows for coastal exposure. PGT and CGI build impact-rated products that hold up against the bay’s wind-driven moisture, and ES Windows makes a marine-grade aluminum line we trust for custom shapes and oversized panels. We register both manufacturer warranty layers in writing before the truck leaves the driveway. That is the Custom Windows & Doors standard we apply to every job, in Seaside or anywhere else we work, and it is backed by our Done Right Promise.
Common Custom Windows & Doors Problems We See in Seaside Homes
- Corroded aluminum jalousie frames. The single most common replacement call in the 93955 ZIP. Salt-laden fog eats the frame channels until the louvers seize and the glass rattles loose. These windows cannot be meaningfully weathersealed; the frame is the failure point, not the seal.
- Rotted wood sills and door jambs. Homes built in the 1940s through 1970s off Broadway Avenue and Noche Buena Street predate modern flashing tape and sill pans. Four decades of fog-wetted wood is not a repair job; it is a tear-out and rebuild.
- Failed seals on dual-pane insulated glass. Inland, a dual-pane unit might go fifteen or twenty years before the argon leaks out. On Fremont Boulevard, three blocks from the fog line, a non-marine-grade IGU can fog out in five. We see it constantly.
- Doors that bind in summer, leak in winter. The mild temperature swing in Seaside hides a moisture cycle that swells wood and corrodes steel hinges. A door that only misbehaves seasonally is usually a frame or threshold issue that a standard change-out will not fix.
Pricing for Custom Windows & Doors in Seaside, CA
A full custom window replacement in Seaside typically runs $900 to $2,600 per window for a standard sized custom unit in vinyl or aluminum. Custom shape windows run higher, $1,200 to $3,800, because of the fabrication and reframing work. Architectural grilles and SDLs add $150 to $1,400 per window depending on whether you choose interior, interior-and-exterior, or true divided lites. Oversized glass panels start around $1,800 and run past $6,000 for laminated, tempered, or impact-rated glass. The biggest variable in Seaside is frame material: marine-grade aluminum or fiberglass costs 20 to 40 percent more than standard vinyl up front, but it is the difference between a window that lasts and one that repeats the original failure. Every estimate from us is a written line-item quote, and estimates are free. Call (888) 635-0804 to schedule one.
Key Takeaways for Seaside Homeowners:
- Jalousie windows in the 93955 ZIP are almost always replaced, not repaired. The aluminum frame itself is the failure point after 50 to 80 years of salt fog.
- Marine-grade frame materials and stainless/hot-dip hardware cost more up front but are the difference between a ten-year window and a thirty-year one in Seaside’s climate.
- Free written line-item estimates. No change orders, no surprise line items on the bill.
- A live person answers the phone 24 hours a day, 7 days a week. Call (888) 635-0804.

FAQs - Custom Windows & Doors in Seaside
Jalousie windows are common because they were standard on the post-WWII tract homes and duplexes built to house Fort Ord military families, and Seaside has an unusually high concentration of that housing stock. A jalousie cannot be meaningfully weathersealed against coastal fog, because the louvered glass slats ride in exposed aluminum channels that corrode and open gaps; replacing the seal does nothing when the frame itself has lost its shape. The practical fix is full-unit replacement with a modern double-hung or casement window. We recently replaced a bank of original aluminum jalousies on a 1950s duplex off Noche Buena Street near the former Fort Ord. The frames had corroded so badly the sash would not close, and the louvered slats rattled with every gust off Monterey Bay. We reframed the rough openings and installed fusion-welded vinyl double-hungs with low-E glass and argon fill. For a Seaside jalousie replacement, expect to pay $1,200 to $2,800 per window depending on size and frame material. Call (888) 635-0804 for an exact quote.
Salt air corrodes aluminum and steel fasteners fastest, rots wood sills where moisture sits constantly, and is hardest on uncoated aluminum frames. Marine-grade aluminum with a proper anodized or powder-coated finish holds up far better, which is why we spec it frequently in Seaside. Vinyl handles the moisture well and is the most cost-effective choice for standard replacement windows. Fiberglass outperforms both in coastal conditions but carries a higher material cost. The common thread is hardware: we specify stainless or hot-dip galvanized screws, hinges, and brackets on every Seaside job, because standard zinc hardware rusts within a few years in this climate. Cheap inland-spec hardware is false economy; you pay again within a decade. Call (888) 635-0804 and we will show you the difference on a written quote.
Yes. Seaside’s temperatures rarely climb above 68 degrees or drop near freezing, so the heating and cooling savings from new windows are modest compared to inland climates. The real driver here is hardware failure and moisture damage: corroded frames, fogged seals, rotted sills, and doors that no longer close. Homeowners in the 93955 ZIP replace windows because the old ones have failed, not because the utility bill is high. That means the material spec should prioritize longevity and coastal performance over insulation rating alone. Call (888) 635-0804 and we will price the job on the actual failure, not a marketing pitch.
A marine-grade spec includes stainless or hot-dip galvanized hardware throughout, a frame material rated for salt exposure (marine-grade aluminum, fiberglass, or fusion-welded vinyl), and sealants and flashing tape designed for constant humidity and salt-laden air. The glass package may include a low-E coating but the more important upgrade is the edge seal and spacer system, which is what fails first in coastal conditions. This spec typically adds 20 to 40 percent to the material cost of a window compared to a standard inland spec. It is the difference between a window that lasts ten years in Seaside and one that lasts thirty. We will show you both options on a written quote, side by side, so you decide with your eyes open. Call (888) 635-0804 for pricing on your specific openings.
Yes, oversized glass panels can be safely installed in Seaside, but they require structural framing and laminated or tempered glass rated for the bay’s wind load. A large fixed panel facing open water is not a standard window with a bigger hole in the wall; it is a structural component. We design the opening reinforcement, specify the glass thickness and lamination to meet local wind requirements, and install with marine-grade hardware and sealants. In Seaside, an oversized glass panel typically starts around $1,800 and can exceed $6,000 for floor-to-ceiling tempered glass with a reinforced marine-grade frame. The installation is covered by our Done Right Promise and both manufacturer warranty layers registered in writing. Call (888) 635-0804 to schedule a free estimate for your specific wall and view.
