We know Tiburon’s housing stock well. Our crews work along Tiburon Boulevard, through the Old Tiburon flats, and up into the hillside neighborhoods above Paradise Drive. We’ve measured rough openings in 1920s bungalows and 1960s split-levels alike. That matters because Tiburon homes rarely accept a stock window without some adjustment. The estimate you get from us reflects what our crew actually sees, not what a catalog assumes.
Why Meridian Windows & Doors Is Tiburon’s Preferred Window Replacement Company
Meridian Windows & Doors operates as part of the Garrison Partners family, and every job in Tiburon runs to The Garrison Standard: a written price before work starts, background-checked technicians in uniform, and a 365-Day Done Right Promise in writing. If something fails within that year, we return at no charge. That guarantee applies to labor and installation on every window we replace in Tiburon.
Tiburon homeowners deal with specific conditions: salt air off Richardson Bay, fog that lingers on west-facing exposures, and wind that finds every gap in an older frame. We stock and install products from ViewLux, PGT, and CGI because those lines hold up to coastal moisture and meet the thermal demands of Marin County’s Title 24 energy code. Our team answers the phone live around the clock, so when you call about a window project on a Tuesday evening, you talk to a person who can schedule the estimate, not a voicemail.
Elliot Vance leads our window replacement work. He insists that every estimate includes a line-by-line scope, the permit path, and a realistic calendar. No vague allowances, no “we’ll figure it out on site.” The price goes on paper, and it does not move at the door.
Window Repair in Tiburon
Window repair in Tiburon most often means replacing failed insulated glass units, rebuilding sashes that have swollen or rotted from bay moisture, or re-flashing a frame that’s letting wind-driven rain into the wall. A fogged double-hung in a hillside home off Tiburon Boulevard is usually a seal failure, and the fix is a new glass unit sized to the existing sash, not a full replacement. Simple glass replacement in Tiburon runs $350 – $850 per unit depending on size and coating. Sash repair or re-flashing work runs $600 – $1,400 per window based on access and how much rot has to be cut out.
Insulated Glass Unit Replacement
When the seal between two panes fails, condensation builds inside the glass and the view gets hazy. In Tiburon, where views are a large part of why people buy a home, a failed unit has to go. We measure the existing sash, order a matching low-E unit (a thin coating that reflects heat while letting light through), and swap it without disturbing the frame.
Sash and Frame Reseal
Older wood windows near the water take a beating. We remove the sash, repair what’s salvageable, and reseal the perimeter so air and water stay outside. For windows that are too far gone, we’ll tell you straight and quote a replacement instead.
Window Replacement Company in Tiburon
A window replacement company in Tiburon has to handle more than swapping glass. Older hillside homes here have non-standard rough openings that are often out of square by half an inch or more. Stock replacements don’t fit, and forcing them in leaves gaps that become air leaks. Full-frame replacement in Tiburon runs $1,800 – $2,800 per opening for most homes, while insert replacements run $900 – $1,600. The spread reflects frame condition, glass package, and whether the opening needs carpentry work before the new unit goes in.
Full Frame Replacement
We pull the entire old window down to the rough opening, correct the framing, flash the sill and jambs, and set a new unit that’s sealed properly for Tiburon’s wind and rain. This is the right call when frames are rotted, out of square, or no longer meet WUI (Wildland-Urban Interface) requirements for the area.

Insert Replacement
When the original frame is solid and square, an insert fits inside it. It’s less invasive and costs less. On many 1960s and 1970s Tiburon homes, the aluminum frames are sturdy enough to accept an insert with new glazing that improves comfort and cuts noise from the 101 corridor.
Trusted Brands We Service in Tiburon
Meridian Windows & Doors is authorized to install and service products from PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. For Tiburon homeowners, the brands that matter most are PGT and CGI, both of which build impact and WUI-compliant units suited to Marin County’s fire-zone requirements, plus ViewLux for larger glass packages on view-facing elevations. Because we draw from eight manufacturer lines, the window we spec is the one that fits the opening and the exposure, not the one that happens to be sitting in inventory. Parts and replacement units for these brands arrive quickly, and our local crews handle the install without shipping the work to a distant subcontractor.
Common Window Replacement Problems We See in Tiburon Homes
- Out-of-square rough openings in pre-1980 construction. Homes on the hillsides above Paradise Drive and in the Old Tiburon flats often have framing that has settled or was never square to begin with. Stock windows won’t seat correctly, so we measure every opening individually before ordering anything.
- WUI and Title 24 compliance gaps. Tiburon sits in Marin County’s wildland-urban interface, which means replacement windows and exterior doors must meet specific glazing and frame requirements. If the scope misses this, the permit stalls and the glazing has to be re-spec’d.
- Salt air and coastal moisture damage. Houses within a mile of Richardson Bay absorb salt-laden air, which corrodes aluminum frames and rots wood sashes faster than inland homes. We see deteriorated sill pans, failed corner seals, and rusted hardware that needs full replacement rather than a quick fix.
- Hillside access for material and ladder work. Some lots on the steeper streets drop away from the road, leaving no flat staging area. Window deliveries and old-unit removal on those sites require hand-carrying, scaffolding, or in rare cases a crane. That labor appears as a line item, quoted before you sign.
Pricing for Window Replacement in Tiburon, CA
Most single-window replacements in Tiburon run $900 – $2,800 installed, with an average around $1,600. Insert replacements on standard openings run $900 – $1,600, and full-frame work runs $1,800 – $2,800. Larger picture windows on view-facing walls can reach $4,000 – $6,000 because of glass size, laminated interlayers, and the additional labor to set them. What changes the number: opening size, whether the frame is salvageable, WUI glazing requirements, and site access on hillside lots. We deliver a written line-item quote before any work starts, and that price does not move unless you change the scope.

FAQs About Window Replacement in Tiburon
Yes. Tiburon requires a building permit for window replacement when the opening size changes, when the work involves a full-frame replacement, or when the home sits in a designated WUI zone with mandatory glazing requirements. Like-for-like insert replacements sometimes qualify for an over-the-counter permit through Marin County, but we confirm the exact path before we quote so there are no surprises after the contract is signed. Call (817) 686-2228 and we’ll walk you through what applies to your address.
A standard insert replacement for 8 – 12 windows takes 2 – 4 working days once materials arrive. Full-frame work runs 1 – 2 days longer because of the framing and flashing work at each opening. Custom-sized units for out-of-square openings add 2 – 4 weeks of lead time before installation begins. We give you a start date and a finish date in the written quote, and we hold to both.
Opening size is the first driver, then the glass package. WUI-compliant glazing with laminated interlayers costs more than standard insulated glass but is required in many Tiburon neighborhoods. Frame material matters, as does whether the rough opening needs carpentry to square it up. Hillside access adds labor when old windows have to be hand-carried down stairs or a ladder can’t sit level. We show you every line item before you approve the job. Call (817) 686-2228 to get a price broken down the same way.
Potentially, yes, especially on west-facing elevations that get hammered by afternoon sun. Modern low-E glass reflects a significant portion of solar heat, which keeps rooms cooler without closing blinds. One project we completed off Tiburon Boulevard involved west-facing sliders that turned the living room into an oven by 3 p.m. After we installed low-E insulated units, the homeowner said the room stayed noticeably cooler through the afternoon. The energy savings depend on your existing windows, but replacing single-pane or failed double-pane glass usually helps.
Three things, and all of them can be caught during the estimate if the contractor actually opens the window and measures the rough opening: hidden rot in the framing, an opening that’s out of square by more than expected, and WUI requirements that force a glazing upgrade. That’s why we measure every opening, check the permit path, and inspect the site access before we write your quote. We don’t play the lowball-then-change-order game. The price we put in writing is the price you pay unless you decide to change the scope. Call (817) 686-2228 to schedule the free estimate and see the numbers for your specific windows.
