Wood, stucco, and older aluminum siding take a real beating along the Santa Cruz coastline. Constant fog moisture, salt air, and UV exposure cause cracking, fading, warping, and — eventually — water intrusion that damages the structure underneath.
Beyond the cosmetic toll, failing siding is one of the biggest sources of drafts and moisture problems in older homes, driving up energy bills and creating conditions for mold and rot in your walls.
At Airtight Siding & Windows, we’ve been replacing siding across Santa Cruz County for over 30 years. We install CertainTeed Celect and CraneBoard solid-core vinyl — two of the most durable products available, both engineered specifically for coastal climates.

added insulation value with CraneBoard
We install the full range of CertainTeed Celect and CraneBoard profiles, available in dozens of fade-resistant colors and textures — including options that closely mimic the look of wood and fiber cement.

Wide vertical panels with narrow battens covering the seams. A striking, modern-farmhouse look that pairs well with contemporary and coastal architectural styles. Best for: modern farmhouse style

A decorative groove near the top of each panel creates subtle shadow lines and added depth — a popular upgrade for homes wanting more visual texture. Best for: added architectural depth

The classic horizontal overlapping board look. Versatile, timeless, and the most popular choice for ranch and craftsman-style homes across Santa Cruz County. Best for: classic & craftsman homes

A cellular PVC siding system that eliminates the buckling and warping common with hollow-back vinyl. Premium feel, true-to-color finish, and a 75-year limited warranty. Best for: premium, low-maintenance

Solid EPS foam-core construction adds insulation value (up to R-4) and a heavier, more substantial feel that closely resembles wood or fiber cement. Best for: insulation & solid feel

Clean, contemporary, rustic or traditional, there’s a horizontal siding to express whatever your personal style and home's aesthetic is.
We’ve refined this process over 30 years and hundreds of siding installations across Santa Cruz County. No shortcuts, no subcontractors—our own crew handles every step.
We will come to your home to assess your existing siding, discuss your goals, and provide an exact written estimate.
Our crew removes the existing siding and inspects the sheathing and framing underneath for any moisture damage before installing new materials.
New siding is installed to manufacturer specifications, with all trim, corners, and flashing details finished cleanly. Most single-story homes are done in three to five days.
New siding and trim can result in a remarkable transformation and improve the curb appeal of your home. It’s quick and cost-effective too! We can handle everything from removing and replacing the old siding quickly and cost-effectively to improving your property’s curb appeal and value. In Monterey, and Santa Cruz counties, the leading choice for having new siding installed on your home is Airtight Windows and Siding.
Centrally located at 3621 Soquel Drive in Soquel, we proudly serve homeowners throughout Santa Cruz and Monterey Counties with no hidden travel fees.

As a certified CertainTeed Celect and CraneBoard installer, every project we complete is backed by full manufacturer warranties — not a generic contractor guarantee.
CertainTeed Celect carries a 75-year limited warranty with a transferable provision for subsequent homeowners. CraneBoard’s solid-core construction is backed by its own long-term performance warranty against cracking, fading, and impact damage.
Both products are engineered for coastal durability — resisting salt air, moisture, and UV without painting, caulking, or sealing. Our own workmanship guarantee covers the installation itself, so you’re protected from every angle.
Vinyl never rots, swells, or warps from moisture — unlike wood siding exposed to coastal fog.
Color is built into the panel, not applied on top — no scraping, priming, or repainting, ever.
Engineered to withstand the salt, humidity, and UV exposure of Santa Cruz's coastal climate.
CertainTeed Celect's limited warranty is transferable to future homeowners — a real selling point.
CraneBoard's solid foam core adds up to R-4 insulation value — lowering heating and cooling costs.
Airtight's own installation guarantee covers labor and fitting for every siding project we complete.
The clearest signs are drafts around the frame, condensation between the panes, difficulty opening or closing, or noticeably higher energy bills. If your windows are more than 20 years old, even if they look fine, the seals and insulating gas may have degraded enough to affect your home’s efficiency. We offer free in-home consultations where we’ll walk you through exactly what we’re seeing and give you an honest recommendation.
We’re a certified installer of Anlin Windows and Doors — one of the most respected window manufacturers in California. Anlin products carry a lifetime manufacturer warranty, which covers both parts and labor. We carry the full Anlin line including the Del Mar, Catalina, Panoramic, and Coronado series, covering everything from standard single-hung windows to custom bay and bow configurations.
We install the full range: single-hung, double-hung, double slider, single slider, casement, awning, picture, bay and bow, garden, and geometric windows. Whether you need a pocket replacement (new window in the existing frame), a full frame replacement, or windows for new construction, we handle all three installation methods.
Most residential window replacement projects are completed in one to two days depending on the number of windows and any additional exterior work required. We had a customer in Santa Cruz whose nine-window replacement was finished in just one and a half days. Our team manages every detail from arrival to cleanup so there’s minimal disruption to your day.
Window replacement cost depends on several factors: window size, glass type (single, double, or triple pane), frame material, style, grid pattern, color, and the number of windows being replaced. Full-frame replacements or windows requiring exterior siding work will affect the total as well. We provide free, no-pressure in-home estimates tailored to your home’s specific needs and your budget. Call us at (831) 462-9695 or request a quote online to get started.
It covers bigger things, like curb appeal, resale value, mood and self-expression. When it comes to how your siding presents itself, color is crucial. So we pay a lot of attention to what’s trending and what works.
We serve Santa Cruz, Capitola, Aptos, Soquel, Scotts Valley, Watsonville,
and all surrounding communities.
