AfterFast, Reliable Door Installation Across Novato
Door installation in Novato runs $1,200 – $4,800 for a standard exterior door swap, and $2,800 – $8,500 for a French door or slider replacement, depending on whether the opening needs reframing, reflashing, or drainage correction.

Call (562) 478-8017 and we’ll explain what your specific door opening needs.
Why Lightwell Windows & Doors Is Novato’s Preferred Door Installation Company
Keith Yamada leads Lightwell Windows & Doors, part of the Cedarwell network since 2010, and the way we run a Novato job reflects what homeowners here actually deal with: bay-salt corrosion on aluminum sliders, patio slabs that pitch toward the house, and county-versus-city permit questions that most door companies wave off. We don’t. Every Novato install gets a written price before we touch the opening. Our technicians are background-checked and uniformed, and they follow the C.A.R.E. values on site: Clean up like it’s our own home, Ask before moving anything, Respect your family’s time and quiet hours, and Explain the price before the work starts.
Novato homeowners call us after other crews left sawdust under the kitchen table or handed them an invoice that didn’t match the estimate. That’s what the 365-Day Done Right Promise is for: if the finished door isn’t right, we come back and make it right. No debate, no countdown. And when you call with a question at 9pm about a door that won’t latch, a live person answers. Not a phone tree.
Exterior Door Installation in Novato
Exterior Door Installation in Novato means more than swapping a slab in a jamb. Our Door Installation team starts by checking what’s behind the existing casing: whether the rough opening has proper flashing, whether the threshold sits above or below finished grade, and whether the door faces the afternoon heat that pours into Novato’s valley in July and August. Most Novato exterior door replacements run $1,200 – $3,400 for a standard steel or fiberglass unit, with the higher end covering rotted jamb repair or a custom-size opening common in Hamilton Landing’s converted military structures.
Threshold and Drainage Correction
Novato Valley lots from the 1960s and 1970s were often poured with patios that slope flat or slightly toward the house. A replacement door set on that old threshold will weep water under the sill during winter storms. We re-grade or add a raised sill so drainage moves away from the jamb, and we re-flash the rough opening before the new door goes in.
Steel-Frame and Non-Standard Openings
Hamilton Landing holds a distinct pocket of former Hamilton Air Force Base structures with steel-frame door surrounds and military-spec dimensions that don’t match off-the-shelf units. We measure, order, and trim to those specific openings rather than forcing a standard door into a non-standard hole.
French Door Installation in Novato
French Door Installation in Novato is one of the most common upgrades we do for ranch homes with shaded rear yards and older sliding glass doors that have corroded shut or fogged between panes. A French door set for a standard 60- or 72-inch opening typically runs $2,800 – $5,600 in Novato, with the top of that range covering an active door plus fixed sidelite configuration or a custom finish. Homeowners choose French doors when they want the patio access to open wide for evening air, without fighting a steel track that’s been rusted by San Pablo Bay salt for 40 years.
Replacing a Failed Slider With a French Door
When a Novato slider has seized on its rollers, you don’t just replace the door; you often have to demolish the old track out of the wall. That labor is real and it’s specific to homes in Ignacio and lower Hamilton where delta breezes carry salt moisture off the bay and weld aluminum tracks solid. We quote that removal time upfront so you’re not surprised.
Insulated Glass and Solar Gain
A west-facing French door on a Novato summer afternoon will heat a living room fast. We order insulated glass units with low-E coatings through our supplier network, including Therma-Tru and ViewLux, so the door handles the sun without cooking the space behind it. Pet-safe sealants at the sill and threshold are standard on our French door installs.
Trusted Brands We Service in Novato
Novato homeowners get a squarely honest recommendation because Lightwell carries eight manufacturer lines and no single vendor bias. For interior French doors and exterior entry units, we regularly install Therma-Tru and ViewLux. For coastal-adjacent properties in Ignacio and Hamilton where salt corrosion is relentless, we recommend PGT and CGI units engineered with corrosion-resistant hardware and impact-rated glass. Because we stock common replacement parts and weatherstripping for these brands locally, a follow-up adjustment in Novato usually happens in days, not weeks. We’re not Novato residents guessing at what Novato needs; we service the city every week.
Common Door Installation Problems We See in Novato Homes
- Thresholds below grade: Concrete patios on Novato Valley slabs were often poured flush or sloping toward the house, so the replacement door sits lower than the surrounding grade and water runs in during winter rains. We raise the sill or cut a drainage channel before installing.
- Bay-salt corrosion on aluminum sliders: Ignacio and Hamilton get delta breeze salt that welds aluminum tracks and rollers solid. These doors have to be demolished out rather than lifted off, which adds non-standard removal labor we quote up front.
- County permit gaps on acreage: A door swap on a city-limit house usually needs no permit, but a detached shop or ADU door on unincorporated Marin County acreage does. We check the parcel’s jurisdiction before we quote so you don’t get flagged at resale.
- Well and septic setback conflicts: On Novato acreage, a new door opening within a well or septic system’s required separation distance has to be scoped against Marin County health department rules. We run that check before a single jamb goes in.
Pricing for Door Installation in Novato, CA
Here’s what Novato homeowners can expect to pay, in real numbers. A standard exterior entry door replacement runs $1,200 – $3,400, depending on whether the jamb is rotted and whether we’re pulling a permit.

FAQs About Door Installation in Novato
No permit is needed for most single-family exterior door replacements inside Novato city limits, because you’re swapping a door in an existing opening. On unincorporated Marin County acreage, a detached shop, outbuilding, or ADU door does need a county permit, especially if the opening touches a well or septic setback. We check your parcel’s jurisdiction before quoting. Call (562) 478-8017 and we’ll tell you which path applies to your address.
The rot is usually from water, not the door itself. Novato Valley slabs often have patios poured flat or sloping toward the house, so every winter storm drives water under the threshold and into the wood jamb and subfloor. Add spring and fall rain to a door that already sits below grade, and the bottom rail and jamb legs rot within a few seasons. We fix the drainage first, then install the new door so water never pools at the opening again. Call (562) 478-8017 to schedule a look at the threshold.
In most cases, yes. Hamilton Landing has some converted military-era structures with steel-frame surrounds and non-standard openings, but we measure and order to those exact dimensions rather than cutting a bigger hole. If the existing frame is corroded past saving, we remove it surgically and rebuild the rough opening with the same wall-plane alignment. The wall stays intact. Call (562) 478-8017 and we’ll tell you what your specific opening will take.
We correct the drainage before we set the new door. That means either raising the sill on a new pan flashing, regrading a small section of patio, or cutting a shallow drainage channel so runoff moves away from the jamb. On open Novato lots with visible grade slope, we also check that the surrounding soil isn’t directing water back toward the slab. The correction is quoted as line-item labor before the door goes in, not as a surprise after. Call (562) 478-8017 for a free estimate on the whole fix.
Yes, and the effect is real because Novato sits in an inland valley that runs 10 – 15°F hotter than coastal Marin towns. A new insulated exterior door with proper weatherstripping stops the direct solar gain through an old aluminum frame, and an insulated glass French door with low-E coating reduces afternoon heat transfer on south- and west-facing openings. The energy savings are highest on those sun-exposed sides, which is where most Novato doors fail first. Call (562) 478-8017 and we’ll price the door for your most exposed elevation.
