Why Juniper Windows & Doors Is Inverness’s Preferred Window Installation Company
We’ve replaced windows on Sir Francis Drake Boulevard, in the Seadrift lagoon area, and up the winding roads off Pierce Point Road where the morning fog sits against the glass for hours. That local repetition matters. When we measure an opening in Inverness, we already know the jamb is probably swollen from decades of marine moisture, the original flashing was likely installed before people understood wind-driven rain here, and the trim profile matters to you more than a sales brochure would ever suggest.
Sean Mackey leads our crews, and the standard we hold on every Inverness job is simple: written price first, photo proof during, and a full year of coverage after. If something isn’t right, we fix it. 365 days, parts and labor, in writing. That’s the 365-Day Done Right Promise, and it applies to every unit we install in the Point Reyes area.
Booking works the way people in Inverness actually live now. You call, a person answers, we schedule, and you get a live arrival time you can track from your phone. The Relay Visibility Guarantee is the name for it. No four-hour windows, no “the tech is running late” text if there’s no tech coming at all. Before-and-after photos get sent to you, and the final invoice is digital.
Window Contractor in Inverness
A window contractor in Inverness handles more than setting glass into a frame. We scope the opening, check for hidden rot in the rough framing, spec the right glass package for coastal exposure, coordinate the Marin County permit when the opening changes size, and pull the permit ourselves. Homeowners in Inverness call us when a double-hung has seized from salt corrosion, when a sliding door track has warped from years of marine moisture, or when they’re ready to replace every opening on a bluffside home before the next winter storm cycle.
Typical window contractor scoping and installation work in Inverness runs $1,200 to $3,800 depending on unit count, frame condition, and access. If the rough opening needs resetting, add $400 to $900 per opening.
Coastal Frame Assessment
Older Point Reyes-area homes were remodeled in stages, and rough openings rarely match the nominal window size stamped on the old unit’s label. We measure the actual opening, not the old window. Skipping that step is the most expensive mistake we see in Inverness.
Marine-Grade Hardware Specification
Standard fasteners and hinges fail within a few years in salt fog. We specify stainless hardware and corrosion-resistant flashing on every exterior-facing component, and we write it into the line-item quote so there’s no surprise upcharge later.
Window Installers in Inverness
Window installers in Inverness do the hands-on work: removing the old sash and frame, resetting or repairing the rough opening, installing the new unit, sealing and flashing the exterior, and trimming the interior to match what was there. Inverness homeowners call us when a window has failed and they want the replacement done cleanly, without a sales pitch and without the original trim profile getting butchered in the process.
Installation labor in Inverness typically runs $450 to $900 per opening. The glass and frame package is separate and usually lands between $450 and $2,500 per unit depending on style and glass spec.
Rough Opening Reset
We reset the rough opening when the existing framing is out of square or water-damaged. That’s the step most quotes skip, and it’s the step that determines whether your new window operates smoothly or binds at the latch in year two. We price it in writing before work starts.
Exterior Sealing and Flashing
Interior trim work alone won’t keep Inverness weather out. We flash and seal the exterior face of every opening, because wind-driven rain on the Point Reyes peninsula finds every gap within a season or two if the detail isn’t done right.
Trusted Brands We Service in Inverness
We install and service windows from CGI, CWS, and ES Windows. Each is a product line we know well enough to spec correctly for Inverness conditions. CGI’s laminated impact-rated glass makes sense on a bluffside home where wind-borne debris is a seasonal reality. CWS offers clean sightlines that fit the mid-century ranches around the Seadrift area. ES Windows handles the oversized fixed and picture units that Inverness homeowners like for bay views. We stock common replacement hardware locally and can turn most parts orders around faster than a big-box special order.
Common Window Installation Problems We See in Inverness Homes
- Sizing off nominal dimensions: Older Point Reyes-area homes have been remodeled in stages, and the actual rough opening rarely matches the old window’s label. We measure the opening, not the sticker, and catch this before the unit is ordered.
- Salt-fog hardware corrosion: Standard hinges, fasteners, and balances corrode within a few years on the Inverness ridge. We specify stainless hardware on every exterior-facing component, because replacing it twice is more expensive than spec’ing it once.
- Missing exterior flashing details: Interior trim work isn’t enough when wind-driven rain hits Sir Francis Drake Boulevard homes from the west. The exterior weather-sealing and flashing detail is what keeps the rough opening dry, and it’s where budget installs fail first.
- Swollen jambs from persistent fog: Salt-laden fog sits on Inverness windows for hours each morning. Older wood jambs absorb that moisture and swell, which seizes sashes. We see it most often on double-hungs from the 1980s and 1990s.
On a Sir Francis Drake Boulevard bluffside home, our crew replaced a failed double-hung whose jamb had swollen from salt-laden fog and whose sash hardware had seized. We reset the rough opening, installed a laminated-glass unit with a stainless-steel hinge set, and the homeowner gained a clear, weather-tight opening without altering the original trim profile. That’s the standard we bring to every Inverness job.

FAQs About Window Installation in Inverness
Yes, when the rough opening changes size or structural framing is altered, Marin County requires a building permit, and the work must pass a final inspection. We pull the permit ourselves, coordinate the inspection, and include the fee in your written quote. If we’re swapping an insert into an existing opening with no structural change, a permit is typically not required. Call (682) 281-2168 and we’ll tell you which path applies to your specific windows.
Most Inverness window installations take 6 to 10 weeks from signed quote to final inspection. The glass and frame order runs 3 to 6 weeks depending on the product line and whether you need laminated or impact-rated glass. Installation itself is usually 1 to 3 days for most homes in the Seadrift or Sir Francis Drake Boulevard area. Our written quote includes the timeline, so you know the calendar before anything gets ordered.
Access, glass spec, and frame condition drive most of the cost beyond the window unit itself. Bluffside homes on Sir Francis Drake Boulevard often need scaffolding or ladder work, which adds labor. Coastal exposure usually means laminated glass and stainless hardware, which adds material cost. And older Point Reyes-area homes frequently need rough opening resets, because decades of marine moisture have compromised the framing. Our quotes break all of this out line by line.
Hidden rot in the rough framing is the most common change-order trigger. When we remove the old window and find the sill plate or studs are water-damaged, that framing has to be repaired before the new unit goes in, and that’s additional work. We photograph everything and send you images before any extra work proceeds. Our written quote also states exactly what would trigger a change order, so you know in advance what’s covered and what isn’t. Call (682) 281-2168 for a quote that spells this out.
Yes. Inverness sits inside the coastal wildland-urban interface of Point Reyes, so window swaps here are driven by fire-resistant construction details and salt-air corrosion more than by cooling-season heat gain. That means laminated glass for impact and fire resistance, stainless hardware for salt corrosion, and exterior flashing detailed for wind-driven rain. It’s not regional marketing. It’s the difference between a window that lasts 30 years and one that fails in six. We spec every unit to those conditions and write it into the quote.
If you’re ready to get a real number for your Inverness windows, call (682) 281-2168. We’ll scope the job over the phone, send a written line-item quote, and you’ll know exactly what it costs before anything gets ordered. Free estimates, no pressure, no vague math.
