How much does window replacement cost?

Cost depends on the number of windows, the frame material, and the glass package you choose. After we measure your openings and talk through your goals, we give you a clear, itemized written estimate — free and with no obligation.

How long does window installation take?

Most window replacement projects are completed within a few days, depending on how many windows are involved and the condition of the openings. We confirm a firm timeline before we start.

Should I replace all my windows at once?

Not necessarily. Doing them all at once is usually the most cost-effective and gives the most consistent look, but we're happy to phase the work if that fits your budget better. We'll walk you through the trade-offs during your consultation.

Will new windows lower my energy bills?

They can. Modern Low-E, double- or triple-pane windows installed with a properly flashed and sealed opening cut drafts and heat loss — which usually means a more comfortable home and lower heating costs.

#1 Window Installer in King and Snohomish County

Warmer, quieter, drier — windows installed to last.

A window is only as good as the install behind it. We've seen beautiful windows leak within two winters because the opening was never flashed correctly. We pan-flash every opening, foam-seal the perimeter, and return the trim properly so your new windows perform exactly the way the energy rating promises. Mr. Elk Exteriors is a window replacement contractor serving Seattle and the Eastside.

How We Do It

Our professional process

1
Measure & glass package
We measure each opening and walk you through frame materials and Low-E glass packages — balancing comfort, noise reduction, and budget for your specific exposure.
2
Careful removal
We remove old units cleanly and inspect the rough opening for rot or prior water damage. Anything we find gets documented before we proceed.
3
Pan-flash & set
Every opening gets a sloped sill pan and proper flashing so any water that gets behind the trim drains out, not into your wall. The window is set level, plumb, and shimmed correctly.
4
Seal & insulate
We low-expansion foam-seal the perimeter for an airtight, draft-free fit — no fiberglass stuffed in the gap and called done.
5
Trim & finish
Exterior trim returns and interior casing are installed and caulked to match your home, then we clean up every scrap of old glass and frame.

What's included

Full-frame and retrofit replacements
Vinyl, fiberglass, and clad-wood frames
Double- and triple-pane Low-E glass packages
Egress-compliant bedroom windows
Custom trim and casing to match your home's style
