Door installation in San Rafael runs $1,200 to $4,800 for most entry doors, $900 to $3,200 for storm doors, and $2,800 to $7,500 for sliding glass doors, installed.

We’re Westlight Windows & Doors, and we’ve been doing this since 2009 as an independently owned and operated Kingswell location. Call (903) 354-7134 and a real person answers, 24 hours a day. We’ll give you a written price before any work starts.
What makes San Rafael different from every other Marin city we serve? The fire-hazard overlays in the hills, the tight lots with shared drives, and the old wood-frame doors downtown that have been fighting bay wind and winter rain for eighty years. We know these streets. We know what the Marin County building department will flag before you even open the permit application. That’s the value of hiring a team that actually works here, not one that drives up from the flatlands and learns your lot on the day of install.
Why Westlight Windows & Doors Is San Rafael’s Preferred Door Installation Company
We show up in the window we gave. That sentence sounds simple, but if you’ve been burned by a contractor before, you know it’s the whole game. Every San Rafael job gets a written arrival window before we ever park a truck. When we say Tuesday between 8 and 10, that’s when we’re there. If something changes, a live person calls you, not a text from a bot.
Our San Rafael customers come back to us for the second door, the third window, the sliding glass door after the entry door. Why? Because Owen Satterfield runs this location the same way he has since 2009: say the price before the work, leave the place cleaner than we found it, put the guarantee in writing, and come back if it fails. That’s the Kingswell Way, and it’s printed on every quote we hand out.
We carry eight manufacturer lines, so when a Dominican homeowner needs an impact-rated entry door for a fire-zone parcel, we’re not trying to force a standard slab into the opening. We spec what the opening and the overlay require. Therma-Tru for the Canal bungalows, PGT or CGI for hill homes facing wind and ember exposure, ViewLux for a tight backyard slider that needs every inch of glass. The right product, matched to the job, not the other way around.
Every technician who walks onto your San Rafael property is background-checked and uniformed. You’ll know their name before they ring the bell. When the job’s done, we hand you a written guarantee that covers the work for 365 days. If it’s not done right, we make it right. No charge, no negotiating.
Storm Door Installation in San Rafael
Storm door installation in San Rafael is the most cost-effective way to protect an older entry door from the valley’s punchy afternoon heat and the winter rain that funnels down from the hills. We install custom-fit storm doors starting around $900 for a basic aluminum unit, up to $3,200 for a full-view glass storm door with a retractable screen. A storm door works double duty here: it shields the primary door from solar heat gain that climbs 15 to 20 degrees above Sausalito on a July afternoon, and it adds a second weather seal against the northerly bay winds that push rain into door sills all winter.
Protecting Original Entry Doors
A lot of Terra Linda ranch homes still have their original 1950s and 60s entry doors. They’re solid, but the finish is tired and the weatherstripping is dead. A storm door buys those doors another decade without a full replacement. We measure to the opening, not the old door, so the reveal and clearance come out right every time.
Fire-Zone Considerations
In the Dominican and Sun Valley hills, a storm door counts as part of the exterior assembly. If your parcel falls in a CAL FIRE designated Very High Fire Hazard Severity Zone, the storm door frame and glass spec may need to meet ember-resistant standards. We handle that paperwork and spec the right unit so the permit doesn’t stall. Come back to us if it does, and we’ll fix it at no charge under the 365-Day Done Right Promise.
Sliding Glass Door Installation in San Rafael
Sliding glass door installation in San Rafael turns a dark back wall into light and access, and on a tight hillside lot, that matters more than almost anywhere else in Marin. We install sliders starting at $2,800 for a basic two-panel unit, up to $7,500 for a multi-slide or French-style slider with low-e glass. West light, the late-afternoon sun that pours through a good window, is the whole point. A properly installed slider catches every last hour of it.
Small Backyard Solutions
Hillside homes in Sun Valley often have a back wall that opens onto a ten-foot patio and then a slope. A swinging door eats four feet of that patio. A slider uses none. We spec ViewLux sliders for these tight spaces regularly because the narrow stiles put maximum glass in the opening without demanding a structural header rework.
Threshold and Drainage Work
Any slider in San Rafael’s valley floor needs a proper sill pan and drainage. Winter storms drive rain sideways into north-facing exposures on the Canal and downtown streets. We pull the old sill, inspect for rot in the subfloor, and flash the new pan before the door ever goes in. If the rough opening shows water damage, we stop and show you before we proceed. That’s the Kingswell Guarantee in action: a written price for the work we can see, and a straight conversation about anything we find once the old door is out.
Trusted Brands We Service in San Rafael
We install doors from Therma-Tru, PGT, CGI, and ViewLux, and we keep common replacement parts and weatherstripping for these brands stocked in our Bay Area warehouse. That means when a San Rafael customer needs a threshold or a hinge or a latch matched to an existing door, we’re not waiting a week on a parts shipment. For impact-rated entry doors in the hills, we quote PGT and CGI assemblies that meet Marin County’s ember-resistance requirements without overbuilding the opening. For the Canal’s wood-frame bungalows, we like Therma-Tru fiberglass slabs that never rot and never need paint. The brand follows the need, not the other way around.
Common Door Installation Problems We See in San Rafael Homes
- Rotted wood-frame jambs in the Canal and downtown. Homes from the 1920s through the 1940s have original fir jambs that funnel winter rain and bay wind straight into the rough opening. By the time we’re called, the bottom six inches are often gone and the door no longer swings true. We repair the jamb, flash it, and seal it before the new slab goes in.
- Fire-overlay permits stalling a simple door swap. In the Dominican, Sun Valley, and East San Rafael hills, a like-for-like door replacement can trigger the CAL FIRE Very High Fire Hazard Severity Zone review. If the assembly isn’t ember-resistant or the rough opening wasn’t structurally checked, the county won’t sign off. We document the opening and spec compliant assemblies on every hillside quote.
- Street staging conflicts on narrow lots. A lot of San Rafael homes have no driveway, or a driveway shared with a neighbor. We stage materials on the sidewalk, keep one parking spot, and hand-carry everything through a side gate. It keeps the neighbors onside and the site cleaner than we found it.
- Single-pane aluminum sliders failing from heat load. Terra Linda’s 1950s and 60s tract homes still carry original single-pane sliders in a surprising number of cases. The valley heat cooks those frames and the insulated glass seals fail early. We’ve pulled sliders out of Terra Linda homes where the frame was so warped the panel wouldn’t glide without lifting the whole slab.
Pricing for Door Installation in San Rafael, CA
A standard entry door replacement in San Rafael runs $1,200 to $4,800 installed, depending on the slab, the jamb condition, and whether your parcel sits in a fire-overlay zone. Storm doors run $900 to $3,200. Sliding glass doors run $2,800 to $7,500. The fire-zone review itself doesn’t add much to the labor line, but an ember-resistant, non-combustible assembly costs more than a standard door. A rotted jamb adds $200 to $500 in repair work before the door goes in. Every quote we write includes all of this in writing before work starts. No revised invoices at the door. Call (903) 354-7134 for a free estimate.

FAQs About Door Installation in San Rafael
Yes, in most cases. Parcels within the CAL FIRE designated Very High Fire Hazard Severity Zone are subject to Marin County building department review for ember-resistant assemblies and non-combustible frame materials. A like-for-like door replacement that would sail through a permit in the flatlands can require a structural check of the rough opening and a compliant assembly in the hills. We handle the documentation and spec on every hillside quote so the permit doesn’t stall. Call (903) 354-7134 to talk through your specific parcel.
It affects staging and access more than the door itself. Homes with no driveway or a shared drive mean our crew stages materials on the sidewalk and hand-carries everything through a side gate. We keep one parking spot and never block a neighbor’s access. That’s factored into the quote as a staging line item, typically $150 to $300 depending on distance from truck to opening. We show you the written price before work starts.
Yes, and we do it regularly in Sun Valley and the Dominican hills. A slider is usually the best choice on a tight backyard because it doesn’t swing into the usable patio space. We quote ViewLux sliders for narrow stiles and maximum glass, and we handle the header and rough-opening work that a hillside retrofit sometimes requires. The Kingswell Guarantee covers the full installation in writing, including a free return visit if anything fails within the guarantee period.
The Canal sits low and sheltered, but the winter storms that funnel through the valley drive rain straight into north-facing door sills. Add 80 to 100-year-old wood-frame jambs and the bottom of the jamb rots out faster than doors in Larkspur or Kentfield. We repair the jamb before installing the new door, flash the sill, and seal the threshold so water doesn’t find the same path twice. A Therma-Tru fiberglass slab eliminates the rot problem entirely.
No, there’s no formal neighbor notice required for a door installation in San Rafael. But on a tight lot with a shared driveway, we knock on the door next door before we start if our staging will affect their access. It’s common courtesy and it prevents problems before they start. We’ll tell you during the estimate if your lot’s access will touch a neighbor’s property and how we’ll handle it.
If you’re ready to get a written price for your door installation in San Rafael, call (903) 354-7134. A real person answers, day or night. We’ll schedule your free estimate, show up in the window we gave, and hand you a written quote before any work begins. No door-step surprises, no revised invoices, no disappearing contractor. That’s the Kingswell Way.
