Fast, Reliable Window Installation Across Seaside
Window installation in Seaside, CA runs between $600 and $1,800 per opening for most 1940s-1970s tract homes and duplexes, with full jalousie-to-casement replacements on Fort Ord-era housing typically landing between $900 and $1,400 per unit. That price reflects something specific about this city: the salt air off Monterey Bay has been eating aluminum window frames here for fifty years, and half the work our crews do in the 93955 ZIP starts because the original hardware has failed, not because a homeowner wanted an upgrade. We know Seaside’s housing stock down to the street level, and we quote jobs here with an eye toward what the marine fog will do to a window twenty years from now. Call (888) 635-0804 for a free estimate.
Key Takeaways:
- Full Window Installation in Seaside typically costs $600-$1,800 per opening, depending on frame material and condition of the rough opening
- Jalousie windows in Fort Ord-era tract homes are the single most common replacement call in Seaside
- Salt fog from Monterey Bay corrodes aluminum frames and kills dual-pane seals faster here than anywhere else in the county
- Vinyl, fiberglass, and marine-grade aluminum are the only frame materials we specify for Seaside’s coastal exposure
Why TruePane Windows & Doors Is Seaside’s Preferred Window Installation Company
TruePane has spent years working the Monterey Bay coastal edge, and the work we do in Seaside is not the same work we’d do ten miles inland. The fog is thicker here, the salt is heavier, and the housing stock is older than what you’ll find in most of the surrounding cities. Our technicians know that a 1955 duplex off Broadway Avenue has different framing, different flashing conditions, and different failure patterns than a 1980s single-family over near Del Monte Heights. That matters when you’re deciding whether to repair or replace, and it matters more when you’re deciding what to replace with.
We’re led by Dale Kessler, a second-generation glazier who founded TruePane in 2008 because he was tired of watching homeowners get quoted windows that were wrong for their climate and then told “that’s standard practice” when the seal failed in year six. Dale’s rule is the one that names the company: if the pane is not true, the job is not done. Our crews in Seaside measure every opening twice, quote manufacturer lines side by side on paper, and register both warranty layers before the truck leaves the driveway.
Homeowners in Seaside want to know we’ll still answer the phone in ten years. We answer it now, 24 hours a day, 7 days a week, with a live person. Not a voicemail tree. Not a regional call center. A real person who can talk about your specific house and your specific windows.
Our Window Installation Services in Seaside
Casement Windows
Casement windows are our workhorse replacement for Seaside’s Fort Ord-era stock. We install casements with stainless steel operators and fusion-welded vinyl or marine-grade aluminum frames because those are the only configurations that hold a seal against Monterey Bay’s salt fog for more than a decade. In the 93955 ZIP, a casement replacement for an original jalousie or single-pane aluminum unit typically runs $900-$1,500 per window, including flashing and sill capping. Most Seaside jobs are done in one visit.

Sliding Windows
Sliding windows replace the old aluminum sliders and jalousie banks we see constantly along Noche Buena Street, Hilby Avenue, and the duplex blocks near General Jim Moore Boulevard. The original sliders in those 1950s and 1960s tract homes have tracks that are now so corroded the sashes bind mid-travel. We install new sliders with marine-grade stainless rollers and interlocking meeting rails that actually seal. Expect $600-$1,200 per window for a standard replacement in Seaside, more if the old frame has rotted the rough opening.

Fixed & Picture Windows
Fixed picture windows are common on the front elevations of Seaside’s mid-century homes, often paired with jalousie side units. The big fixed panes are where fogged dual-pane units are most visible: south- and west-facing picture windows in this marine environment lose their argon fill within five to ten years, clouding the glass and killing the insulation value. We replace those units with dual-pane low-E glass, argon fill, and a properly taped and flashed rough opening. Typical pricing in Seaside runs $500-$1,000 for a standard-size fixed window replacement.
Sliding windows and fixed picture units together make up the bulk of our full-system retrofits on Seaside’s tract houses and duplexes. We also install awning, bay and bow, and garden windows throughout the city, but if you’re on a Fort Ord-era property, the casement and slider work is where our local experience earns its keep.

Trusted Brands We Service in Seaside
We’re an authorized installer for more than a dozen manufacturer lines, and we service what we install. For Seaside’s salt-air conditions, we consistently specify Milgard, PGT, CGI, and ES Windows, because those are the frames and glass packages built to hold up on the Monterey Bay edge. If you’re in Seaside and you have a failed Andersen or Pella unit, we service those too. What we don’t do is sell you a window that looks good for two years and puffs the seal in year four. New or replacement, every unit we install in the 93955 ZIP goes in with flashing tape at the jambs, marine-grade sill capping where the old aluminum or wood has failed, and both warranty layers registered in writing before we leave.
Common Window Installation Problems We See in Seaside Homes
- Jalousie windows that cannot be weathersealed. The louvered glass-slat units in Seaside’s 1940s-1970s Fort Ord tract housing leak air and moisture 24 hours a day. There is no retrofit seal that works; the only fix is full replacement with a proper operable window like a casement or slider.
- Corroded original aluminum frames. Single-pane aluminum windows on near-original rental stock have spent fifty to eighty years in marine air. The sash channels and weep holes clog with oxide, trapping water against wood sills that were never flashed to modern standard.
- Failed dual-pane seals from fog and marine moisture. Units on south- and west-facing elevations in Seaside lose their argon fill within five to ten years. The window fogs, the glass looks milky, and the insulation value drops to nearly zero.
- Rotten wood sills and jambs from chronic condensation. Seaside’s near-constant humidity means interior moisture and exterior fog meet at the sill. Original wood trim on these older homes rots from both sides, and the rough opening needs real repair before a new window can be set correctly.
Pricing for Window Installation in Seaside, CA
Window installation in Seaside runs from about $600 for a standard fixed window replacement up to $1,800 or more for a large casement or a custom bay unit on a Fort Ord-era home with a rotted rough opening. The price difference between a vinyl casement and a marine-grade aluminum casement is real, typically $200-$400 per window, but on the Monterey Bay edge the cheaper spec often costs more within a decade when the operators corrode or the frame channels clog with salt oxide. We quote both options side by side, on paper, with line-item pricing and no surprise line items on the bill. Call (888) 635-0804 to schedule your free estimate. Standing offer for seniors and veterans: 5% off every job, permanently.

FAQs - Window Installation in Seaside
Jalousie windows are common in Seaside because the city’s housing stock was built in the 1940s-1970s to house Fort Ord military families, and jalousie units were cheap, fast, and suited to the mild climate at the time. They fail in Seaside because the louvered glass slats cannot be sealed against Monterey Bay’s salt fog; air and moisture move through them around the clock, the aluminum frames pit and corrode, and the crank mechanisms seize. Full replacement is the only lasting fix. Call (888) 635-0804 for a quote on replacing yours.
Yes. Seaside sits in the thickest part of the Monterey Bay marine fog belt, and salt air settles on window frames nightly. Aluminum frames that last thirty years in Salinas will show visible pitting and oxide clogging within a decade in the 93955 ZIP. The operators, the weep holes, the sash tracks: everything aluminum corrodes faster here. The fix is a material change: fusion-welded vinyl, fiberglass, or marine-grade aluminum with stainless hardware.
Fog between the panes is a failed insulated glass unit. The argon fill has leaked out, moisture has replaced it, and the window has lost nearly all of its insulation value. In Seaside’s marine fog, this happens on south- and west-facing elevations within five to ten years of installation on lower-quality units. It will not dry out, and it will not get better. Replacement of the glass unit or the full window is the proper fix. We can quote both options.
For Seaside’s salt fog, we specify fusion-welded vinyl with stainless hardware, or marine-grade aluminum with the same stainless operators. Wood frames, even well-painted, absorb moisture from both the fog outside and the condensation inside, and they rot at the sills faster here than they do inland. Cheap aluminum is the worst choice: it pits, oxidizes, and binds within a decade on the Monterey Bay edge.
Because much of Seaside’s Fort Ord-era housing stock has been held as low-turnover rental property since the base closed in 1994. Owners have deferred window and door upgrades for decades; the units still rent, so there’s little pressure to replace. What that means for a homeowner buying one of these properties now is that the windows are likely original or near-original, with all the corrosion and seal failure that implies. Our crews have done dozens of full-system replacements on exactly these houses. Call (888) 635-0804 and we can walk you through what you’re looking at.
If you’re in Seaside and you’re tired of fogged glass, stuck operators, or windows that rattle with every fog line off the bay, call TruePane at (888) 635-0804 for a free estimate. We’ll measure, quote the right window for this climate, and put it in writing before we touch a single fastener.
