Window Replacement in Anacortes, WA

Wind and salt air off the water reach most of Fidalgo Island, and that exposure shapes how windows age in Anacortes as much as rain does. Census data puts the median home here at 1989, which means a large share of houses still have their original windows, now decades into their service life. We install new vinyl windows from the Preservation 9000 line, each one custom-made to the measured opening, with hardware chosen for a marine setting.

Windows in Anacortes homes today

Anacortes has 8,801 homes, and their windows split clearly by decade. Census data shows the largest group, 31%, was built from 1980 to 1999. Those houses typically got first-generation vinyl windows, and after decades of service the seals between panes are the usual weak point.

Another 30% of homes went up in 2000 or later. Many of them have builder-grade windows that were chosen for price when the house was built and are now reaching the point where owners start replacing them room by room.

Older homes make up the rest. About 24% date from 1950 to 1979, an era of aluminum frames and early vinyl, and 16% were built before 1950. Houses from before 1950 often still have single-pane glass in wood sashes, and their painted trim may contain lead, which changes how old units are removed.

Most of this housing is single-family. Detached houses account for 77% of homes and attached homes for 12%, so most window projects here involve a full house of openings on several walls rather than a single unit. That makes it worth planning the whole house at once, even if you replace in stages.

Heating costs, comfort and efficiency in Anacortes

Natural gas is the main heating fuel in Anacortes, but a sizable minority of homes depend on electric heat: 27%, according to Census data. Propane heats another 2% and wood 1%, and no homes here report heating with oil.

For the electric, propane and wood-heated homes, efficient windows pay back faster, because every unit of heat that leaks through old glass is expensive to replace. If your home has baseboard heaters or an electric furnace, the windows are one of the most direct ways to cut that loss. Gas-heated homes still gain comfort near the glass and fewer cold spots, even if the cost difference is smaller.

Comfort matters here beyond the utility bill. On an island with steady marine wind, tired weatherstripping and worn seals around old sashes let outside air in on the windward side of the house. A new unit, measured and set into the opening with fresh seals, closes those gaps.

PSE supplies electricity in Anacortes. We don’t quote rebate programs because they change, so check with PSE for current programs before you choose windows. During the consultation we can give you the window sizes and styles you would need to ask about.

Choosing replacement windows for Anacortes

We install Preservation 9000 vinyl replacement windows, and Builders Service Company is the only company in Washington that provides them. Each is custom-made to your openings. Here is how we usually match them to Anacortes homes:

  • Hardware for the marine air. Salt air corrodes exposed metal over time, so on waterfront and wind-exposed lots we pair the vinyl frames with corrosion-resistant hardware and fasteners.
  • Views on the water side. Large fixed picture windows and bay or bow units suit walls that face the water, while operable casements on either side bring in a breeze when you want one.
  • Fresh air where moisture builds. Awning, hopper and casement windows open wide in kitchens and bathrooms and can be placed high on the wall for privacy.
  • Specialty styles for higher-value homes. The median home value in Anacortes is about $695,000, roughly 48% above the Skagit County median, and owners here more often choose premium options such as garden windows, bay and bow units and custom shapes.

Seventy percent of Anacortes homes are owner-occupied, so most of the people we work with plan to live with these windows for a long time and choose accordingly.

Signs your windows need replacing

In an Anacortes home from the 1980s or 1990s, the clearest sign is a hazy or foggy look between the panes that won’t wipe off. That means the seal has failed and the insulating gap between the glass is no longer doing its job. Sashes that stick, rattle in the wind or won’t latch are another sign.

Older aluminum frames from the 1950s through 1970s tend to collect condensation on the inside on cold mornings, and the water can stain sills and wall finishes below. On pre-1950 houses, look for soft or rotting wood at the sills and lower sash, and drafts around the frame.

Near the water, also check the hardware. Cranks, locks and hinges that have pitted or seized from salt air are a common reason to replace the whole unit rather than repair it.

Anacortes window replacement FAQ

Does PSE offer rebates on replacement windows in Anacortes?

PSE is the electric utility in Anacortes, so it is the right place to ask, but its program list changes and we can't promise any rebate. Check with PSE for current programs before you order, especially if your home is one of the 27% heated with electricity. We can then size and quote Preservation 9000 windows for every opening during a free in-home consultation.

What should I replace first in a 1980s or 1990s Anacortes home?

Start with the windows whose seals have failed: units that look foggy or hazy between the panes, plus any sash that sticks or no longer locks tight. Homes from those decades usually have first-generation vinyl windows, and they rarely fail all at once. We check each opening during the consultation so you can see which windows need attention now and plan the rest of the house in phases.

Do salt air and wind off the water change which windows I should buy?

They change the hardware more than the window type. Anacortes has lower rainfall than much of western Washington, but marine wind and salt air are constant on Fidalgo Island, and they wear on exposed metal. On homes with waterfront exposure we install Preservation 9000 vinyl windows with corrosion-resistant hardware and fasteners, and we look at which walls face the water before choosing operating styles.

Can you replace windows on an Anacortes house built before 1950?

Yes. About 16% of homes in Anacortes predate 1950, and many still have single-pane or early windows set in wood frames. Old paint on those frames may contain lead, so we treat it with care during removal. Double-hung Preservation 9000 windows keep the traditional up-and-down look, and each unit is custom-made to the measured opening rather than forced into a stock size.

Can I finance new windows or get a discount?

Yes. Financing is available, and you can review the current options on our [financing page](/financing) or go over them during the consultation. We also offer discounts for seniors, active military, veterans and first responders. We also offer a lifetime warranty, and our Washington contractor license number is BUILDSC027JN if you want to look us up before we visit.

  • Builders Service Co. installed vinyl windows in our home many years ago, and vinyl siding a couple years ago. Both times were an excellent experience given the size and complexity of the jobs. Inconvenience was minimal and the results were exemplary.
