Fast, Reliable Sliding & Patio Doors Across Woodside
Our Custom Windows & Doors in Woodside service handles sliding and patio door replacement that runs $2,800 to $9,500 for a standard 6-foot unit, and $12,000 to $35,000 for panoramic multi-slide systems on the larger estate homes. Most jobs take one to two days once the unit is on site, though fire-code compliance and structural repairs can extend that. If you’re off Whiskey Hill Road or Mountain Home Road, call (888) 635-0804 and we’ll schedule a time to walk your door openings, check the sills, and give you a written line-item quote before any work starts.
We know Woodside’s housing stock and we know the WUI Chapter 7A requirements that come with it. Our Sliding & Patio Doors team works on these wooded hillside homes year-round, so we arrive already understanding what redwood duff does to a sill pan and what the town’s design-review board will ask for when you pull a permit.
Why TruePane Windows & Doors Is Woodside’s Preferred Sliding & Patio Doors Company
We’re not the cheapest bid in Woodside, and we don’t try to be. We’re the company homeowners call after a national installer put in an off-the-shelf slider that failed the fire inspection, or after fogged glass on a 1970s patio door sat unrepaired for five years because nobody wanted to touch the rot behind it.
Dale Kessler started TruePane in 2008 after growing up around glazing work, and the rule he keeps on the whiteboard still governs every job: if the pane is not true, the job is not done. Our technicians are background-checked and uniformed, they measure every opening twice, and they quote manufacturer lines side by side on paper so you see exactly what you’re paying for. We register both warranty layers in writing before the truck leaves your driveway because a warranty that isn’t registered doesn’t protect anyone.
Woodside homeowners call us specifically because we already know the local code path. The Very High Fire Hazard Severity Zone designation is not a surprise to us. We spec Chapter 7A-compliant units from the first quote, not after a failed inspection puts your project on hold.
When you call, a live person answers, 24 hours a day, seven days a week. No phone tree. No call center halfway across the country. (888) 635-0804.
Our Sliding & Patio Doors Services in Woodside
Every door we install in Woodside gets matched to the home and the lot. Heavily canopied properties need different track systems than open ridge lines. Older ranch homes need different frame profiles than the newer estates off Mountain Home Road. Here’s what we handle most often:
Patio Sliding Doors
Door Installation - Woodside projects for standard 6-foot and 8-foot patio sliders are the most common replacement we do, and they’re also where we find the most hidden damage. On a 1960s ranch home off Mountain Home Road, we pulled a failed Milgard slider and found the sill framing behind it rotted clean through from years of redwood duff packed into the track. Our crew sistered in new pressure-treated framing, flashed the opening with butyl tape lapped over the WUI-rated pan, and reset a heavy-duty unit with tempered glazing, then re-trimmed to match the original redwood profile the town’s design review required. That’s the difference between swapping a door and doing the job right.

Panoramic Sliding Systems
The view out the back of a Woodside estate is usually why the house was built there in the first place, and our Window Installation - Woodside team knows how to protect it. Panoramic multi-slide systems from ES Windows or CWS open up a wall of glass without the post-and-beam clutter of older patio door layouts. These are heavy units, typically 3 to 5 panels, and they require precise roller alignment and a dead-level sill to operate properly a decade from now. We set them on reinforced substrate with proper drainage, and we negotiate the Chapter 7A glazing requirements so the openable area ratio passes inspection without sacrificing the view.

Heavy-Duty Sliding Doors
Woodside’s custom homes often have oversized openings that stock doors can’t fill. Heavy-duty sliding doors with reinforced frames and commercial-grade rollers handle the weight of large glass panels without sagging or binding. On lots where oak leaf debris and redwood duff pack into the track year-round, we spec sill pans with positive drainage and recommend stainless or anodized track covers that shed debris instead of trapping it. If your current slider binds in July but not January, that’s thermal movement in the frame, and it’s usually a fix we can complete the same visit.

Pocket & Barn Doors
Pocket doors and barn-style sliders work well in Woodside homes, especially where hallway space is tight or where an interior door opens onto a patio. The catch is that pocket door hardware is buried in the wall, so a cheap roller fails quietly and turns a smooth door into a wrestling match. We use ball-bearing hangers rated for the door weight, and on exterior-facing pockets we pay extra attention to the jamb seals because marine fog finds every gap and feeds condensation into the cavity. If the door is going to separate conditioned space from an unheated mudroom or garage, we’ll talk through the seal package before we quote.

Screen Door Installation
A good sliding screen door on a Woodside home has to handle two things: bugs in spring and wind-driven debris the rest of the year. We build and install replacement screen doors with frames matched to your existing slider or patio door, and we use pet-resistant mesh where dogs and kids are part of the household. Frames are available in wood-look finishes that keep the town’s design-review office happy.

Trusted Brands We Service in Woodside
We’re an authorized installer for more than a dozen manufacturer lines, and for this area we lean on the ones that hold up to marine fog and woodside debris: ES Windows and CWS for panoramic and multi-slide systems, CGI for impact-rated and WUI-compliant units, and ECO Window Systems for energy-efficient replacements on older ranch homes. We keep common slider rollers, seals, and track components in local stock so a repair doesn’t wait on a parts shipment from two states away. When we quote, we put the manufacturer line, the warranty term, and the glazing package side by side on paper so you can compare what you’re actually buying.
Common Sliding & Patio Doors Problems We See in Woodside Homes
These are the patterns we see most often in Woodside, and they rarely show up on a national website’s list of generic door problems because this town’s conditions are specific.
- Sill rot from debris-packed tracks. On the heavily canopied lots off Whiskey Hill Road, redwood duff and oak leaves pack into the track, trap standing moisture, and rot the sill framing behind the door unit before the glass or hardware ever fails. By the time the door binds, the structural damage underneath is already done.
- Fogged glass from marine fog and seal failure. Woodside gets measurably more ambient moisture than flatland neighbors like Redwood City, and that fog works its way into every minor seal breach in an older dual-pane unit. A straight glass-pack replacement is a frequent fix here, and it’s usually half the price of a full new door.
- Chapter 7A non-compliance. Off-the-shelf sliding doors without fire-rated glass or ember-resistant frames fail Woodside’s WUI inspection outright. We’ve had homeowners show us quotes from companies that don’t know the requirement, and the reorder alone sets the project back six to eight weeks. We spec it right the first time.
- Frames that no longer match.
The strict rural-character design review in Woodside means your replacement door has to match the existing architectural profile. If the original was redwood-clad or custom-milled, a stock vinyl or aluminum unit won’t pass. Custom wood-clad and fiberglass units are often the only viable option, which is why we carry those lines and quote them accurately.

FAQs: Sliding & Patio Doors in Woodside
Yes. Woodside sits squarely within California’s Very High Fire Hazard Severity Zone, so virtually every window and door replacement on these wooded hillside estates must comply with WUI Chapter 7A fire-resistance provisions, which means multi-pane tempered or fire-rated glass, ember-resistant frames, and restricted openable area ratios. Our Sliding & Patio Doors team specifies Chapter 7A-compliant units from the first quote. If you’ve seen a quote from another company that didn’t mention this, ask them about it before you sign. Call (888) 635-0804 for a code-correct quote.
The redwood duff and oak leaf debris that pack into the track create standing moisture against the sill, and that moisture sits there through the wet winters and the foggy summers, rotting the framing behind the door long before the glass or hardware fails. It’s the single most common hidden repair we uncover on older Woodside ranch homes, and it’s why we check sill substrate before quoting any slider replacement. Call (888) 635-0804 and we’ll inspect yours for free.
In most cases you can replace the glass pack without replacing the entire door, and the cost runs $750 to $1,800. In Woodside’s marine fog, seal failure is common on dual-pane units from the 1980s through early 2000s, and a new glass pack restores the insulation and clears the view. The frame and hardware stay in place. If the frame itself is rotted or warped, then a full replacement makes more sense. Call (888) 635-0804 and we’ll tell you which route your door actually needs.
Our Sliding & Patio Doors in Woodside team works with custom wood-clad and fiberglass units that are milled to match the existing architectural profile your home already has, including redwood and clear cedar profiles common on 1940s through 1970s ranch and rustic estates. When a design-review board wants the new door to look like it was always there, we’ve handled that approval path more times than we can count. Call (888) 635-0804 and we’ll bring color samples and profile options to your door.
We handle them with an inspection first, allowances written into the contract, and any surprise priced and approved in writing before we touch it. We’ve been through enough of these older Woodside homes to know that outdated wiring, undersized framing, and failed waterproofing hide behind the walls, and we don’t want you to find out about a $3,000 sill repair on the day of install. When we pull a door and find something, we take photos, show you what we found, and get your signed approval before work continues. That’s how we’ve always done it. Call (888) 635-0804 to get starting.
