Drafty, single-pane, or poorly sealed windows are one of the largest sources of energy loss in a home. The U.S. Department of Energy estimates that heat gain and loss through windows accounts for 25–30% of residential heating and cooling costs.
For homes along the Santa Cruz coastline, there’s an added challenge: salt air, fog moisture, and UV exposure accelerate the deterioration of wood frames, aluminum frames, and low-grade vinyl — causing them to warp, corrode, and seal-fail well ahead of schedule.
At Airtight Siding & Windows, we’ve been solving exactly this problem for over 30 years. We install Anlin vinyl windows — engineered specifically for California’s coastal climate — with a proven installation process and a warranty that actually means something.

To view the replacement windows we carry, all you have to do is visit our showroom in Soquel, CA. We install the full range of Anlin window styles. Every type is available in multiple grid patterns, hardware finishes, and glass packages — including OceanGuard Low-E for coastal properties.

One or two sashes glide horizontally on a track. Ideal for wide openings or rooms where a swinging sash would be impractical — kitchens, basements, and walkouts. Best for: kitchens, ground floor

Fixed windows that don't open, offering the maximum unobstructed glass area and the clearest possible views. Often combined with casements or double-hungs for ventilation. Best for: ocean views, focal walls

Hinged at the top and open outward from the bottom. Awning windows allow ventilation even during light rain — well-suited to Santa Cruz's mild, wet winters. Best for: bathrooms, winter ventilation

Both sashes slide up and down independently, making cleaning easy from inside the home. The most popular choice for Santa Cruz residential homes. Best for: bedrooms, living rooms

Hinged on the side and cranked open outward. Casements create an airtight seal when closed and maximize ventilation — excellent for capturing coastal breezes. Best for: coastal views, ventilation

Three or more windows joined at angles to project outward from the home, creating additional interior space . Ideal for dining rooms and living rooms. Best for: architectural character

Anlin’s True Lifetime Warranty is one of the most comprehensive window warranties 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 the covered components. It also transfers fully to a subsequent homeowner, which makes Anlin windows a genuine selling point when you put your home on the market.
Our own workmanship guarantee covers the installation itself. If there’s ever a problem with how a window was installed, we make it right — no questions asked.
Lifetime coverage against warping, cracking, or structural defects in the frame profile.
If the insulated glass unit fails or fogs between panes, Anlin replaces it at no cost.
Locks, handles, hinges, and cranks are all covered for the life of the original owner.
Fully transferable to the next homeowner — a documented advantage at point of sale.
Coastal-rated Low-E glass with lifetime coverage against fade, delamination, and seal failure.
Airtight's own installation guarantee covers labor and fitting for every window we install.
Buying new windows involves more decisions than most homeowners expect. Should you choose wood, fiberglass, or vinyl? What style of operation works best for each room — double-hung, casement, sliding? And which matters more for your home: long-term durability or maximum energy efficiency?
Because new windows are a significant investment, it’s important to keep your home’s overall style in mind from the start. Knowing your design direction — whether you’re updating your home’s look or preserving its original architectural character — helps narrow down the right window materials and styles, so every choice supports the home you’re trying to create.
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.
