Better Insulation
Brighter Rooms
Quieter Indoors
Condensation trapped between panes. Frames that stick when you try to open them. Cold air seeping through cracks no matter how high you turn the heat. You live with it for months, hoping the problem stays small.
But worn seals and failing frames only get worse. Energy bills climb. Moisture collects. And the longer you wait, the more those simple repairs turn into full replacements you didn’t budget for.
PNW Prestige Exteriors handles window installations and repairs for Shoreline homeowners who expect durability, clarity, and real energy savings. We install frames that resist rain, seal out drafts, and stand up to daily wear without gaps or leaks.
Our crew works with vinyl, fiberglass, and composite materials, applying proper flashing, shim alignment, and weatherstripping on every job. We repair failed seals, replace cracked glass, adjust sticking sashes, and upgrade single-pane units to double or triple pane systems.
We keep job sites clean, answer questions in plain language, and finish on schedule. When the work is done, your home feels quieter, warmer, and brighter.
Energy-efficient installations and expert repairs that restore clarity, seal out drafts, and improve comfort year-round.
Secure, weather-tight entries that operate smoothly and make every arrival feel like you’re stepping into a well-built home.
Durable cladding that stands up to rain, protects against moisture intrusion, and keeps your exterior looking sharp for years.
Precise trim work that completes the look, resists rot, and frames your home with clean lines that hold up through changing seasons.
No more drafts in winter or hot spots in summer when your windows seal tight and insulate properly.
Energy-efficient glass and frames reduce heating and cooling costs without changing how you use your home.
Modern double-pane construction cuts outside noise so traffic and weather stay where they belong.
The installers arrived on time, measured every opening twice, and replaced all six windows in less than a day. No mess left behind, and the difference in temperature control was noticeable that same evening. They even adjusted one frame that had settled slightly over the years.

We needed one door and two window replacements after a leak damaged the frames. The crew walked us through material choices without pushing the most expensive option, finished the work in two visits, and made sure everything sealed properly before they left.

Every seal and barrier keeps moisture out where frames meet siding.
Frames stay plumb and level so sashes operate smoothly year after year.
Argon-filled panes reduce heat loss and lower monthly energy costs reliably.
Debris is contained and removed daily so your home stays orderly throughout the project.
Locks and cranks are tested and calibrated before final walkthrough.
Vinyl and fiberglass resist warping in rain and sun better than painted wood.
Homeowners across the greater Seattle region count on our window installation and repair expertise. We know how Pacific Northwest weather affects frames, seals, and glass, and every installation is designed to handle rain, wind, and temperature swings year after year.
If you see foggy glass, persistent drafts, or difficulty opening the sash, replacement usually makes more sense. Small hardware fixes and weatherstripping updates are quick repairs we handle on site.
Vinyl and fiberglass frames hold up well against frequent rain and temperature swings. Both resist moisture damage and require minimal upkeep compared to wood or composite options that expand over time.
Most single-window replacements take two to four hours from removal to final caulking. Larger projects with multiple openings typically wrap up in one to two full days depending on access.
When the seal between panes fails, moisture enters and the insulating gas escapes. At that point replacement of the entire insulated glass unit is the only lasting fix for clarity and efficiency.
Yes. We install both exterior trim around the opening and interior casing to finish the reveal. Matching profiles to your existing molding keeps the look consistent throughout the house.
