Questions to ask before you sign
Matt's list for this job.
- Is this an insert replacement or a full-frame replacement, and why is that right for these openings?An insert keeps portions of the old frame, so their condition is central to whether that approach makes sense.
- Can you spell out the window models, glass, opening styles, and finishes on both sides?Glass, opening style, and trim choices can make similarly sized windows very different purchases.
- How much glass area or clear opening will change, and have you checked emergency escape requirements where your code requires them?A smaller usable opening can affect both daylight and an escape route, even if the outside frame fits.
- How will you flash the sill and connect the window to the wall water barrier?Sill flashing gives water a route out when it gets past the outer seal.
- What happens if you find rot, and who handles trim repair, insulation, patching, and paint?Rot repair and restoring the surrounding trim can add work beyond setting the new window.
- Who is responsible for final measurements, permitting, applicable lead-safe practices, and protecting the rooms during installation?Final measurements affect the order, while dust containment and lead-safe work affect the household during removal.
- What is the lead time, and who handles glass failures, leaks, and labor under the warranties?Glass coverage may leave removal and reinstallation labor for you to pay.
Also worth asking
- How will you protect the property and leave it clean at the end of each day?Flower beds, walkways, and household access deserve protection throughout demolition.
- Who is accountable for crew supervision, required permits, and getting a leak repaired after the job?A leaking installation needs a named contact who can arrange a repair without sending you between companies.

How wide is the range in Seattle?
The middle half of window replacement permits in Seattle runs from $7,780 to $16,020, and a tenth of permits sit below $6,370 while a tenth sit above $25,650. A quote outside the middle half is not wrong on its own, but it should come with a reason you can see in the scope, so compare it line by line.
