When Drafts, Fog, and Sticking Frames Make Your Home Feel Uncomfortable

You notice condensation between the panes, air leaking around the sash, frames that bind when you try to open them. Maybe one window never quite closes flush, or the seal has failed and turned every view into a foggy blur.

The longer you leave it, the harder your heating system works. Bills creep higher. The draft you feel standing near the glass makes every winter morning colder than it should be.

Windows That Work Better and Look Better for Decades

PNW Prestige Exteriors specializes in window installations and repairs that deliver lasting comfort and beauty for Sammamish homes. Our team focuses on every detail, from proper flashing and sill prep to choosing the right glazing and weatherstripping for your home.

We work with vinyl, fiberglass, and composite frames, handle both single-pane upgrades and full-frame replacements, and repair failed seals, sticking sashes, and rotted casing. Each installation is squared, leveled, and sealed to prevent drafts and water intrusion that show up months later.

Family-owned and built on punctual service and honest pricing, we stand behind every window we install. Your Sammamish home deserves windows that perform through every season and add real value for years to come.

Honest Reviews from Real Homeowners

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.

Frequently Asked Questions

How do I know if a window needs replacing or just repair?

Cracked glass, broken hardware, or minor seal issues usually call for repair. When frames are rotting, seals are failing across multiple panes, or drafts are driving up your bills, replacement saves more in the long run.

Absolutely. We bring samples of frame profiles, grid patterns, and colors to your home so you can see exactly how the new windows will blend with your siding, trim, and architecture before any work begins.

Most single-room projects finish in a day. Whole-house replacements typically take two to three days depending on the number of openings and any trim work required. Weather can add a day if conditions are unsafe.

The crew protects floors with drop cloths, removes old units, preps each opening, installs the new windows, insulates around the frames, and cleans up debris before they leave. You can use your rooms the same evening.

Yes. Frame repairs cover rot, sill damage, and structural issues around the opening. Glass replacement handles cracked or fogged panes, failed seals, and broken hardware without tearing out the entire unit if the frame is still sound.
