Fast, Reliable Window Installation Across Inverness
Our Window Replacement in Inverness runs $650 – $1,850 per opening for most replacement work, with full-home projects on the Point Reyes Peninsula typically landing between $9,000 and $24,000 depending on unit count, glass spec, and framing condition. We’re Meridian Windows & Doors, part of the Garrison Partners family, and we’ve built our Inverness window practice around one hard fact: this coastal climate punishes the wrong window in about three seasons. Our crew specs low-E insulated glass units with salt-air-rated hardware as standard, writes the price down before work starts, and backs every install with a written 365-Day Done Right Promise. Call (817) 686-2228 and we’ll scope your job properly.

Why Meridian Windows & Doors Is Inverness’s Preferred Window Installation Company
Inverness homeowners sit between two weather systems: fog off Tomales Bay and wind-driven rain straight off the Pacific. We’ve pulled permits in this jurisdiction and we know what the county building department checks on glazing and fire-hardening work. That means the job gets specified correctly the first time, not corrected after a failed inspection. Every technician who walks onto your property is background-checked, uniformed, and held to The Garrison Standard, the operating code our crews have followed since 2009.
Prices go on paper before any work starts. That’s not a policy, it’s how Meridian runs every job. The quote you approve is the price you pay. If something fails within 365 days, the crew comes back at no charge, no labor-exclusion fine print. Our phones are answered by a live person, 24 hours a day, every day. You call, a person picks up. That’s the whole system.
Elliot Vance leads our operation with one rule: do what the written quote says, show up when scheduled, and leave the site cleaner than we found it. We’re not the cheapest bid in Inverness, and we don’t pretend to be. We’re the crew that returns your phone call and stands behind the work in writing.
Window Contractor in Inverness
A window contractor in Inverness handles the full replacement or new-installation scope: removing old sashes and frames, verifying rough openings, re-flashing to current drainage-plane standards, shimming and squaring, installing the new units, insulating the jamb cavity, trimming, caulking, and hauling away the debris. On Point Reyes Peninsula homes, the contractor also has to think about WUI (wildland-urban interface) code compliance, because Inverness sits in a Very High Fire Hazard Severity Zone. That changes glazing choices, flashing detail, and sometimes the permit path. Most single-window replacements in Inverness run $650 – $1,400 installed; a full-frame replacement with rot repair at the jamb lands between $1,200 and $1,850 per opening.
Permit and Code Review
Inverness window work generally requires a permit through Marin County, and replacing windows on an older home can trigger WUI review under California Building Code Chapter 7A. We handle the permit application, pull the documentation together, and coordinate the inspection. The inspector checks glazing type, framing, and fire-rated assembly details. When you hire us, that process is on our side of the table.
What “Done Right” Means on This Coast
Salt air rusts standard window hardware on Tomales Bay-facing homes within two to three winters. We spec frames and hardware rated for coastal exposure, use stainless or coated fasteners, and detail the flashing so wind-driven rain can’t migrate behind the new unit. A meridian is a fixed line you measure everything against. That’s what the name means and how we run every install.

Window Installers in Inverness
Window installers in Inverness are the ones doing the physical work: cutting out old units, setting new ones, flashing, insulating, trimming, and sealing. A good installer crew in this climate knows that fog and salt air mean you don’t skip the corner seals, you don’t reuse rotted framing, and you don’t caulk over drainage paths. On a standard double-hung replacement in Inverness, installed pricing runs $700 – $1,300. Bay and bow units, which require structural support and heavier flashing, run $2,800 – $6,500 installed, and garden windows typically land between $1,700 and $3,400.
Older Homes, Rotted Jambs
Most Inverness housing stock dates to the 1940s – 1970s: redwood-sided cottages and ranch homes built with single-pane wood double-hung windows. After decades of fog and wind off Tomales Bay, the jamb wood swells, rots, and loses its grip on the sash. We don’t set a new window into a rotted opening. We cut out the bad wood, sister in new framing where needed, and only then flash and install. That’s the difference between a window that seals for 20 years and one that leaks again next wet season.
Cleanup and Site Respect
The Garrison Code gets passed to every Meridian crew member: no debris left on site, drop cloths down inside the home, the driveway swept at the end of the day. Inverness lots are tight, the driveways often unpaved and mud-heavy half the year. We plan for that. When the work is done, the old window glass, sashes, and trim go with us. You don’t drag a load to the transfer station.

For homeowners across Inverness, that discipline is the reason they call us first and refer us to neighbors.
Trusted Brands We Service in Inverness
We’re authorized to install and replace products from eight manufacturer lines, and for Inverness work we lean on three in particular: CGI for impact-rated coastal builds, CWS for heavy-duty aluminum frames that hold up to salt air, and ES Windows for clean sightlines in modern renovations. We stock the common replacement parts for these lines locally for Inverness customers, which cuts lead times on warranty callbacks and hardware swaps. If a hinge or crank fails within the guarantee window, we don’t wait three weeks on a freight shipment. We fix it.
Common Window Installation Problems We See in Inverness Homes
- Swollen sashes that won’t close or lock. Years of fog and rain off Tomales Bay swell the wood and bind the sash. If the jamb is rotted, the fix is frame-and-jamb replacement, not forcing the sash shut.
- Corroded locks, hinges, and cranks. Standard inland hardware rusts fast in salt air. Casement and awning windows on western exposures corrode fastest. We replace with salt-air-rated or stainless hardware and order it from the start.
- Wind-driven water behind the new unit. Skipping proper flashing and drainage-plane detailing on redwood-sided homes lets rain run behind the window and rot the jamb. The leak often doesn’t show until the next wet season. We detail every opening to California code and then check that work twice.
- WUI compliance problems at inspection. Inverness sits in a Very High Fire Hazard Severity Zone, and Marin County inspectors check for Chapter 7A-compliant glazing and framing assemblies. Inland-grade windows sometimes fail that review. We spec fire-resistant glazing from the beginning so the inspection passes on the first trip.
On a call in Inverness Park, we replaced a bank of failing single-pane wood double-hung windows on a 1940s redwood cottage. The sashes had swollen so badly they wouldn’t close, and the jamb had dry rot from years of fog and wind-driven rain off Tomales Bay. We installed new low-E insulated glass unit double-hung windows with rot-resistant frames, re-flashed the rough openings, and the homeowner noticed the interior fogging and cold drafts stopped immediately.

FAQs About Window Installation in Inverness
Yes, most window replacement work in unincorporated Marin County, including Inverness, requires a Marin County building permit, and many projects trigger WUI review because Inverness sits in a Very High Fire Hazard Severity Zone. We pull the permit, prepare the documentation, and coordinate the inspection. Call (817) 686-2228 if you want us to check your specific address against current code requirements.
Low-E insulated glass units in corrosion-resistant frames, usually vinyl, fiberglass, or factory-coated aluminum, handle Inverness conditions best. Salt-air-rated hardware is non-negotiable. For west-facing exposures in Inverness Park or along Sir Francis Drake Boulevard, impact-rated CGI or CWS units add storm and fire-hardening value. We spec the window for the exposure, not for what happens to be in stock.
A single standard replacement typically takes 45 – 90 minutes once the crew is on site. A full home of 8 – 12 windows runs 2 – 3 days, plus time for permit approval and inspection, which Marin County can schedule one to three weeks out. We give you the calendar in writing before the first day of work. Call (817) 686-2228 for a project-specific timeline.
Hidden rot at the jamb or rough opening adds framing repair time, and that’s the most common change on Inverness’s older redwood homes. The second common one is WUI glazing upgrades if the original quote didn’t include fire-rated glass. We surface these before the crew starts wherever possible, and any change is written down and approved by you before additional work happens. Nothing moves at the door without your sign-off.
Possibly. Many California carriers offer mitigation discounts for fire-rated or impact-rated glazing in WUI zones, and Inverness is squarely in one. We can provide the product documentation and installation records your insurer will ask for. Ask your agent about Chapter 7A-compliant window and glazing discounts, then call us at (817) 686-2228 with their requirements and we’ll spec to match.
