Why Replace Your Patio Door

Your patio door does more than open and close

A patio door is one of the largest single openings in your home’s exterior — which means it’s also one of the largest opportunities for drafts, water intrusion, and energy loss when it’s old, warped, or poorly sealed.

Along the Santa Cruz coast, aluminum-framed sliders from decades past are especially prone to corrosion, sticking tracks, and seal failure from constant salt air and fog moisture. Beyond comfort, a worn-out patio door is also a security weak point.

At Airtight Siding & Windows, we install Anlin sliding glass and French doors — the same trusted brand we use for windows, with the same True Lifetime Warranty. Most replacements are completed in a single day, with no compromise on California’s safety glazing requirements.

Anlin Malibu Patio Doors

We install the full range of Anlin patio doors, available in multiple panel configurations, hardware finishes, and glass packages — including OceanGuard Low-E for coastal properties.

Sliding Patio Doors

Sliding patio doors are made up of panels of glass that slide open horizontally.

One or two panels glide horizontally on a track, offering the widest unobstructed glass view and the smallest footprint when open. The most popular patio door style.

Best for: limited floor clearance

Swinging French Doors

French patio doors also called double doors or hinged doors, swing in or out. 

Two hinged panels swing inward or outward for a traditional, architectural look. Creates a wide walkthrough opening into a backyard or patio area,  — ideal for craftsman, colonial, and farmhouse-style homes.

Best for: traditional architecture

True Lifetime Warranty

The same lifetime protection as our windows

Anlin patio doors carry the same True Lifetime Warranty as their windows — one of the most comprehensive in the industry — and as a certified Anlin installer, our customers receive the full benefit of it.

The warranty covers the original purchaser for life, with no prorations and no hidden exclusions on covered components. It’s also fully transferable to a subsequent homeowner, which makes Anlin doors a genuine selling point when you put your home on the market.

Our own workmanship guarantee covers the installation itself — including leveling, sealing, and smooth operation. If anything is wrong with how a door was installed, we make it right.

Vinyl Frame

Lifetime coverage against warping, cracking, or structural defects in the frame profile.

Glass Seal

If the insulated glass unit fails or fogs between panes, Anlin replaces it at no cost.

Hardware & Rollers

Locks, handles, rollers, and tracks are all covered for the life of the original owner.

Transferable

Fully transferable to the next homeowner — a documented advantage at point of sale.

OceanGuard Glass

Replacement Patio Door Options: Where to Start?

Upgrading your patio doors improves security, energy efficiency, and curb appeal. From smooth-gliding sliding doors to timeless swinging French doors, we have a style to fit every architectural look. How to choose your perfect match:

Frequently Asked Questions

What's the difference between a sliding patio door and a French door — which is better for my home?

It comes down to your space and your style. Sliding patio doors move horizontally so they never swing into your indoor or outdoor space — ideal if your patio or living room doesn’t have room for a door arc. French doors (also called swinging or hinged doors) open outward or inward and create a more dramatic, architectural entrance to your backyard. Both options are available in the Anlin Malibu line we install, so the decision is really about what fits your floor plan and the aesthetic you’re going for. We’ll help you figure it out during your free consultation.

What patio door brands do you carry in Santa Cruz?

We’re the exclusive regional dealer for Anlin Windows and Doors in this area. The Anlin Malibu patio door line is engineered as a direct companion to Anlin’s window series — same energy-saving technology, same quality construction, same lifetime manufacturer warranty (the most comprehensive in the industry). That means your doors and windows are backed by the same warranty program, which simplifies things significantly for homeowners.

Will a new patio door actually lower my energy bills?

Yes, and noticeably so. Older patio doors — especially aluminum-framed sliders from the 80s and 90s — are notorious for drafts, condensation, and heat loss. Anlin Malibu doors are built with the same energy-efficient glass and framing technology as their windows, which means better thermal performance, reduced air infiltration, and lower heating and cooling costs. Many of our Santa Cruz County customers replace their patio doors specifically because of drafts and immediately feel the difference.

Do you install pet doors in patio doors?

Yes, pet door inserts can be incorporated into patio door installations. This is something we can discuss during your free consultation — we’ll go through the options that work with the door configuration you’re choosing and make sure it’s both functional and properly sealed.

How much does patio door replacement cost in Santa Cruz?

Patio door replacement cost depends on the door type (sliding vs. French), size of the opening, glass specifications, hardware selection, and whether any surrounding exterior work is needed (such as siding repair or new trim). We provide free, detailed in-home estimates so you know exactly what you’re getting and what it costs before any commitment is made.
