Get your free estimateFast, Reliable Door Installation Across Novato
Door installation in Novato usually costs between $900 and $4,800 depending on what we find behind the old unit, and most jobs wrap up in a single day once permits clear. Novato’s housing stock runs heavily toward 1960s-1980s tract homes where the original hollow-core entry doors and aluminum sliders have served decades past their useful life. When we pull those units, what’s behind them often tells a bigger story than what’s visible from the driveway. Call (831) 480-4124 to schedule a walkthrough, and we’ll give you a written price before anything gets touched.
Why Lightwell Windows San Francisco Is Novato’s Preferred Door Installation Company
We’ve worked enough Novato jobs to know the patterns here before we even park the truck. In the Ignacio, San Marin, and Pleasant Valley neighborhoods, certain door failures repeat themselves decade after decade. That local repetition means we arrive expecting specific problems, not discovering them.
Homeowners around Novato tend to mention the same things after we finish: the crew showed up when they said they would, drop cloths went down before tools did, and the final number matched the written estimate. That’s the C.A.R.E. standard our technicians follow on every visit. Clean up like it’s our own home. Ask before moving anything. Respect your time. Explain the price before work starts.
Keith Yamada leads our team, and he has built the operation around a simple rule: write the price down, then honor it. Part of the Cedarwell network since 2010, we carry the 365-Day Done Right Promise on every install. If the finished work is not right, we make it right. No debate, no countdown.

Storm Door Installation in Novato
Storm Door Installation in Novato is a practical upgrade for the entry doors that get hammered by wind-driven rain off San Pablo Bay and morning fog from the Petaluma River corridor. A properly installed storm door adds a layer that protects your main entry door’s finish from UV and moisture, and it buys older doors several more years before full replacement makes sense. In Novato, most storm door installations run $700 to $2,100 including the door, hardware, and labor.
Protection for the Main Entry Door
We see south-facing Novato entry doors with finish damage that could have been prevented with a storm door in place. The outer layer takes the sun and rain, not your primary door. That is particularly relevant for homes along Novato Boulevard where afternoon sun is direct for much of the year.
Pet and Kid-Friendly Considerations
Many Novato families want a storm door with a retractable screen so kids and dogs can come and go without letting the house fill with pollen during dry summer months. We carry hardware options that hold up to dogs pushing through, and we install with pet-safe sealants wherever there is a choice. Nap time matters, so we keep power tools limited to agreed-upon hours.
Sliding Glass Door Installation in Novato
Sliding Glass Door Installation in Novato is one of our most common calls, especially from 1970s homes in Ignacio where the original aluminum patio doors bind against worn tracks and leak during winter storms. Replacing a patio slider in Novato typically runs $1,800 to $4,800. That range accounts for what we find once the old frame comes out, which in this part of Marin often includes rotted jamb material and failed waterproofing that must be addressed before the new unit goes in.
When the Opening Needs Reframing
An older slider opening rarely has the structural integrity of the day it was cut. In Novato’s 1960s-1980s construction, we frequently find undersized headers or sill damage once the old aluminum frame is pulled. We write an allowance into the contract for the likely reframing, then photograph and document anything unexpected before we do it, and only proceed with your written approval.
What the New Door Should Do for the Room
The right sliding glass door changes how a Novato home breathes. Dual-pane glass reduces the winter condensation that forms on single-pane sliders when cool nights meet warm indoor air from furnaces. Look for a door with quality weatherstripping that seals against the North Bay’s wet-season wind, and ask us about low-E coatings that cut heat gain on west-facing rooms in the summer.
Trusted Brands We Service in Novato
We carry and service doors from Therma-Tru, Mr-Glass, and ViewLux, along with five other manufacturer brands in the Lightwell lineup. For Novato customers that means something practical: we can pull from local stock and factory relationships rather than waiting on a single supplier’s timeline. If the 1970s slider in your Ignacio home needs a specific replacement threshold, the part is ordered with the door, not after.
Common Door Installation Problems We See in Novato Homes
- Aluminum sliding patio doors in 1970s Ignacio homes bind and leak during winter storms. The original frames corrode over time, and the tracks drift out of alignment. What starts as a hard pull turns into water on the living room floor by February.
- Hollow-core entry doors from the 1980s fail at the bottom rail. Years of moisture wicking from fog and rain cause swelling at the base, then rot. The door might look fine at eye level and be unsalvageable at the threshold.
- Single-pane wood sashes in pre-war bungalows lose their glazing putty and weatherstripping. Novato’s cool, wet winters push condensation between the panes, and the gaps around the edges let cold air move through the room.
- Failed waterproofing hides behind old door frames. When we pull an original 1970s aluminum slider in Novato, the jamb is often compromised behind a lip of trim. The door looked fine from the outside. The framing did not.

FAQs About Door Installation in Novato
The most common is a structural upgrade to the header and a new requirement for safety glazing if the door sits near a stair or within 24 inches of the floor edge. Novato’s permit process will also typically require the new door to meet current energy code for the climate zone. First sentence of every answer is direct: expect at minimum a glazing and header inspection, and plan for the city to ask for current U-factor ratings. Call (831) 480-4124 for an exact scope on your specific opening, and we’ll tell you what the permit office in Novato will want before we file.
In our experience with Ignacio’s 1970s aluminum sliders, repair is almost never worth the money once the track is corroded and the frame has shifted. The cost to realign and rebuild an aging aluminum slider runs close enough to a quality replacement that the new door is the better financial decision. Call (831) 480-4124 and we will inspect it in person, then give you both numbers in writing.
Yes. Storm doors pair well with pre-war bungalows because they protect the original entry door, which is often worth preserving on that style of home rather than replacing. The job typically includes careful fitting to avoid damaging the existing wood jamb, which on older Novato bungalows is often old-growth Douglas fir. Call (831) 480-4124 for a free estimate, and we will tell you what condition your original jamb is in before any work starts.
Because Novato’s older homes frequently hide failed waterproofing and undersized framing behind the old door, and the contractor did not write an allowance for that into the original number. We handle it differently: the contract includes a written allowance for the likely reframing and flashing work, and we price any additional surprise in writing before touching it. You decide, not us.
A storm door mounts on the outside of your existing front or back entry door and protects it from weather. A sliding glass door replaces a patio opening and is the primary barrier between your living room and the yard. For Novato homes with older entry doors, a storm door often extends the life of the original unit; a slider is a full replacement when the old patio door has failed entirely. Call (831) 480-4124 and tell us which opening is giving you trouble, and we will help you decide which job makes sense.
How We Handle What Opening Up a Novato Wall Uncovers
Novato’s combination of 1960s-1980s tract homes with original aluminum sliding doors and the city’s location in the fog-influenced North Bay means door installation often requires addressing failed waterproofing and undersized framing exposed once walls are open, work that triggers code upgrades under Novato’s local building permits. A simple slider replacement can quietly become a framing, flashing, and inspection job. Our job is to make sure that does not happen after the fact.
We start with an inspection before quoting. That means checking the door from both sides, asking about water intrusion during past winters, and assessing what the rough opening likely looks like behind the trim. Then we write the contract with an allowance for the reframing and waterproofing work we expect to find. If we find something else once the wall is open, we stop, photograph it, and put the new scope and price in writing for your approval. Nothing gets touched until you say yes.
We know what Novato’s permit office expects when framing changes. We know the local building inspector’s focus on glazing safety, header size, and moisture barrier flashing. The job gets done in a way that passes inspection, and the paperwork reflects what was actually installed. That matters when you sell the house.
In the older Ignacio neighborhood, our crew replaced a 1970s aluminum sliding patio door that bound and leaked during winter storms with a Therma-Tru sliding glass door. When we pulled the old unit, we found the original jamb had significant rot from failed waterproofing, so we reframed the opening and installed new flashing before setting the door. That work was already written into the contract as an allowance, so the homeowner approved the extra cost before we touched it.
A light well is what brings daylight deep into a building. That is what a well-installed door should do for your Novato home. Call (831) 480-4124 for a free estimate, and you will get a written price before work starts, a crew that treats your floors and your family’s time with respect, and a 365-Day Done Right Promise on the finished work.
