Fast, Reliable Window Replacement Across Avalon
Window replacement in Avalon, CA costs between $850 and $2,400 per window for most homes, with full-frame projects on Catalina Island typically running $14,000 to $32,000 for a whole house. The island’s barge-dependent supply chain and salt-heavy marine air mean you need a crew that actually understands Avalon logistics, not a mainland team that treats this like any other job. We’ve been coordinating deliveries, permits, and installations here long enough to know that the right window for a hillside home near the Casino is not the same as the right window for a condo in Long Beach. Call (682) 281-2168 to get a written quote before any work starts.
Why Juniper Windows & Doors Is Avalon’s Preferred Window Replacement Company
Avalon homeowners keep calling us back because we plan around the island’s realities, not in spite of them. Every project gets a written price locked before materials are ordered, which matters when a barge schedule slips and you need to know where you stand. Our Window Replacement team has worked on dozens of Catalina Island homes, from beach cottages on Crescent Avenue to hillside properties above Descanso Beach, and we’ve seen what the marine air does to cheap fasteners and standard seals.
Sean Mackey leads every project personally. He’s the one who reviews your quote line by line, confirms hardware specs for salt exposure, and makes sure the crew that shows up in Avalon is background-checked and uniformed. The Relay Visibility Guarantee applies here as much as anywhere: you get a live arrival time you can track, before-and-after photos, and a digital invoice you can pay from a link. No phone tag, no mystery timeline. If anything isn’t done right, the 365-Day Done Right Promise covers it, parts and labor, in writing.
We coordinate scheduling and logistics from our Los Angeles office, but the crews that work in Avalon are island-familiar and plan for ferry and barge timing from day one. That local coordination is the difference between a project that finishes on schedule and one that stalls waiting on a missed delivery.
Window Glass Replacement in Avalon
Window glass replacement in Avalon typically runs $380 to $850 per pane, and it’s the fastest fix when the frame is still solid but the glass itself is fogged, cracked, or salt-etched from years of Catalina’s marine air. We replace the insulated glass unit rather than the entire frame, which keeps costs down and preserves your existing trim. For Avalon homes, we recommend glass with a low-E coating and a warm-edge spacer, because the island’s constant humidity accelerates seal failure on standard double-pane units.
Fogged and Salt-Etched Panes
If your window looks hazy no matter how much you clean it, the seal has failed and moisture is trapped between the panes. On Catalina, we see this earlier than on the mainland, usually within 8 to 12 years, because salt humidity attacks the sealant. Glass replacement restores the view and the insulating performance without a full tear-out.
Impact-Rated Glass Upgrades
Some Avalon homeowners choose to upgrade to impact-rated glass during a glass replacement, especially for windows facing the ocean or the canyon winds. PGT and CGI both make laminated glass units that hold together if struck by wind-borne debris. Glass replacement is a good moment to make that switch, since the frame work is already happening.
Window Sash Replacement in Avalon
Window sash replacement in Avalon generally costs $520 to $1,100 per window, and it’s the right call when the moving parts of the window wear out but the surrounding frame is still square and watertight. The sash is the part that holds the glass and slides or swings within the frame. On Catalina, salt corrosion eats at sash hardware faster than anywhere in LA County, so we frequently replace sashes on windows that are structurally fine but impossible to open or close.
Stuck or Corroded Sashes
We see Avalon homeowners fighting windows that won’t budge because the balance system has seized or the hinges have pitted. A sash replacement swaps in new hardware and a new sash, sized to the existing frame. It’s faster than a full replacement and costs roughly half as much.
When to Choose Full Frame Instead
If the jamb is swollen from moisture or the rough opening has rot, a sash replacement won’t fix it. In those cases, we recommend a full frame replacement, which removes the entire window down to the studs and lets us address any hidden damage from years of ocean exposure. We’ll tell you honestly which path makes sense after we inspect the opening.
Trusted Brands We Service in Avalon
We stock and service windows from CGI, ES Windows, and ECO Window Systems for Avalon customers, because these brands build hardware and coatings that stand up to marine environments better than most. CGI’s impact-rated line is a favorite for ocean-facing properties, ES Windows offers clean sightlines and strong thermal performance for hillside homes, and ECO Window Systems has cost-effective options that still handle salt exposure when properly spec’d. Because we plan material deliveries around barge schedules, we order Avalon projects with the right lead time, which means fewer stalled jobs waiting on a freight slot. You’re never stuck with whatever the local hardware store has on the shelf.
Common Window Replacement Problems We See in Avalon Homes
- Barge delays stalling the job. Materials ordered without lead time for island transport sit on a mainland dock while your project waits. We order early and coordinate delivery windows with the freight schedule, which is why our Avalon timelines hold up more often than not.
- Salt corrosion on standard fasteners and seals. Mainland-grade screws, hinges, and sealants break down in three to five years here. We spec marine-grade fasteners and high-quality sealant on every Avalon job, even if the customer didn’t ask for it, because we’d rather not come back for a callback that was preventable.
- Swollen or pitted frames from years of humidity. Homes near the water absorb moisture into the wood and composite frames. Trying to install a new sash into a compromised frame leads to drafts and poor operation within months.
- Reusing old jamb liners to save money. We’ve seen homeowners try to cut costs by keeping the old jamb and just replacing the sash. On Catalina, that’s usually a mistake, because the liner is often the first thing to fail. We’ll tell you when it’s safe and when it isn’t.
Pricing for Window Replacement in Avalon, CA
Here’s what we see on Avalon projects right now. A single window glass replacement runs $380 to $850. A sash replacement runs $520 to $1,100 per window. Full-frame replacement runs $850 to $2,400 per window, or roughly $14,000 to $32,000 for a whole home depending on size, framing condition, and glass package. Impact-rated glass from CGI or PGT adds 20 to 35 percent, and marine-grade hardware is a small line item that pays for itself in longevity.

FAQs About Window Replacement in Avalon
Most Avalon window replacement projects take 1 to 2 weeks from start to finish once materials land on the island. The biggest variable is barge scheduling, which can add 5 to 10 business days if materials weren’t ordered with enough lead time. We order early and give you a realistic calendar before work begins, not after. Call (682) 281-2168 to get a timeline specific to your project.
Yes, window replacement in Avalon requires a permit from the City of Avalon, and full-frame replacements also trigger a structural inspection. We pull permits and coordinate inspections on your behalf, and every job is inspected and passed before we consider it done. The permit cost is included in your written quote, so it won’t surprise you later.
For Avalon, we recommend CGI for impact-rated ocean-facing windows, ES Windows for thermal performance with clean sightlines, and ECO Window Systems for budget-conscious projects that still need corrosion-resistant hardware. All three offer finishes and components that stand up to salt air better than standard mainland products. We’ll spec the right line for your specific exposure, since a hillside home above Descanso Beach has different needs than a unit on Crescent Avenue.
Salt air corrodes standard fasteners, hinges, and sealants within three to five years on Catalina, causing air leaks, water intrusion, and hardware failure. We use marine-grade hardware and high-quality sealant on every Avalon job, and we recommend low-E coated glass with warm-edge spacers to resist seal failure in the island’s constant humidity. It’s a small investment that prevents callbacks.
Yes, because Avalon’s summer sun hits hillside homes hard, and old or failed windows let a lot of that heat transfer inside. Low-E coated glass and a proper installation reduce solar heat gain, which means your cooling system runs less. In a 1970s hillside home we replaced near the Avalon Casino, the homeowner reported the house stayed noticeably cooler after we swapped fogged double-hungs for PGT impact-rated units with laminated glass and low-E coating.
