Window Replacement in Mount Vernon, WA

Mount Vernon’s housing doesn’t come from a single building boom. Census data puts the city’s median year built at 1989, and its 13,623 homes divide roughly into thirds: older houses from before 1980, homes from 1980 to 1999, and homes built since 2000. That spread means the window you want to replace could be single-pane glass, a 1990s vinyl window showing its age, or a builder-grade window from a newer subdivision. We install Preservation 9000 vinyl replacement windows in Mt. Vernon, and a good plan starts with knowing which of those you have.

Windows in Mount Vernon homes today

Each era of housing in Mount Vernon tends to bring its own window problem.

• Before 1950 (12% of homes): original windows in these houses are often single-pane. Painted sills and trim may also contain lead paint.
• 1950 to 1979 (27%): aluminum frames and early vinyl were the norm. Where they are still in place, they are some of the oldest working windows in town.
• 1980 to 1999 (30%): this is first-generation vinyl. Many of these windows are now well past their best years.
• 2000 and later (32%, the largest group): builder-grade windows that came with the house when it was new and are now reaching the age where they need a closer look.

The type of building matters as well. Census data shows 61% of Mount Vernon homes are detached houses, 13% are attached homes such as townhouses, and 6% are mobile homes. We replace windows in all three, and every opening gets measured on its own, because older houses and later additions rarely share the same sizes.

Many Mt. Vernon homeowners call us about wood window replacement in older houses, picture window replacement, or a new bay window where a flat window used to be.

Heating costs, comfort and efficiency in Mount Vernon

Gas is the most common heating fuel in Mount Vernon, used in 51% of homes according to Census data. Electricity is close behind at 46%, and another 2% heat with propane. That near-even split is the main reason window payback varies so much from one house to the next on the same street.

Efficient windows pay back more where heating costs more, and electric and propane heat both fall on that side. If your furnace runs on gas, comfort may be the bigger gain. If your home heats with electricity, the case for replacing drafty, older windows gets stronger.

Double-pane glass helps hold the indoor temperature steady in both winter and summer, so less of the heat you pay for escapes through the glass. Rooms near large windows feel more even, and the heat doesn’t have to work as hard to keep up.

PSE is the electric utility for Mount Vernon. Programs change, so check with PSE for current programs before you order new windows. We can help you list the windows, sizes and styles you plan to replace so that conversation is easy.

Choosing replacement windows for Mount Vernon

Every window we install is a Preservation 9000 vinyl replacement window, and we are the exclusive provider of Preservation 9000 windows in Washington. Choosing well comes down to matching the window to your house and how you use each room.

• Start with first-generation vinyl. With 30% of homes built from 1980 to 1999, a whole-house replacement in one of those homes often makes more sense than repairing windows one at a time.
• Pick styles room by room. On second floors and under shallow eaves, a slider or casement is easier to live with. A casement, awning or hopper window works well where a kitchen or bathroom needs fresh air. For a living room, a picture window, or a bay or bow window, gives you more glass.
• Plan for the long term. Census data shows 60% of Mount Vernon homes are owner-occupied, and owners who plan to stay often replace all their windows at once so the styles and colors match.
• Weigh value against your home. The median home value of about $470,000 sits right at the Skagit County median, so most homeowners here look for windows that last and suit the house. Vinyl fits that well.

Garden windows and custom shapes are options too.

Signs your windows need replacing

In Mount Vernon, the signs usually depend on the age of the house.

• Fog or haze between the panes. This points to a failed seal, the most common problem in early vinyl and older builder-grade units.
• Water pooling on the glass in winter. Heavy condensation on old glass or aluminum frames means cold glass and a damp room.
• Soft or dark wood sills. Long wet winters work into wood sills and sashes in pre-1950 houses, and rot spreads under the paint.
• Drafts when the Skagit Valley wind picks up. You can feel air at the frame or hear the sash rattle.
• Sashes that stick or latches that no longer lock. Older frames weaken over time, and a window that won’t close tight won’t seal either.
