Windows in Oak Harbor, WA

Windows for Oak Harbor homes, from Builders Service Company.

With a median build year of 1990, many homes here still have their original windows, and a lot of those are first-generation vinyl units with failing seals. The sign is fog or moisture between the two panes of glass. It may clear in nice weather, but it will not get better with time. If one window from the original set is fogging, the others installed at the same time are likely to follow, so replacing the full set is often the cleaner fix.

We install Preservation 9000 vinyl replacement windows, and we are the exclusive provider of Preservation 9000 windows in Washington. Styles include double-hung, slider, casement, awning, hopper, picture, garden, bay and bow, plus custom shapes. A few matches we often make:

  • Casement, awning or hopper windows for kitchen and bath ventilation
  • A garden window over the kitchen sink, with room for potted plants
  • Picture windows, bay or bow windows where you want to frame a view
  • Sliders or casements on upper floors under tight eaves

Heating fuel matters too. Census data shows 52% of Oak Harbor homes heat with electricity and 44% with gas. Drafty windows make either system work harder, and the payback from efficient windows is larger where heating is costly, as it is with electric heat. Electricity here comes from PSE, so check with PSE for current programs before you buy.

Oak Harbor windows FAQ

Why are the windows in my 1990s Oak Harbor home fogging?

Fog between the panes usually means the seal has failed, which is common in first-generation vinyl windows. With a median build year of 1990, many local homes still have them. The fog may clear in nice weather but will not get better with time, and other windows from the same set are likely to follow. Replacement is the fix.

Are there rebates for replacement windows in Oak Harbor?

Electricity here comes from PSE, so check with PSE for current programs before you buy. With 52% of Oak Harbor homes heated by electricity, the payback from efficient windows can be larger. We install Preservation 9000 vinyl replacement windows and are the exclusive provider of Preservation 9000 windows in Washington, and financing is available.

  • John and the team were wonderful, and the work they did on our fascias, windows, and gutters looks great. I would highly recommend them.

  • I’m very happy with the work! The team who came to do the siding was awesome, and it was great working with Mason and Mr. Kim. The siding looks fantastic, and I’m pleased to share that it held up perfectly to the 35mph winds we had last night. I highly recommend them!
