Windows & Doors Estimating Softwarefor Seattle Contractors
If you're bidding windows & doors in Seattle, the gap between a job that nets margin and one that doesn't usually comes down to missing window types or sizes. Drop a plan set in, walk away for 10 minutes, come back to a priced bid you can defend.
What's actually being bid around Puget Sound
500+ window & door installers chasing work in Seattle, growth tracking 10% year-over-year. Average ticket sits around $115,000, labor rates run 35% above the US benchmark, and tech work is what most window & door installers are quoting on this week.
Tech work
Plan sets we see most: tech. Recurring scope items get pre-counted, so you spend the time on the unusual stuff instead of re-counting outlets.
High-Rise work

Green Building work
For green building work specifically, the gotcha is usually Forgetting interior trim. Flag it at takeoff.

Subbing under a licensed GC is one workaround, but on direct-to-owner jobs the homeowner can void the contract if you don't hold the card.

Stuff Seattle window & door installers ask before they sign up
Does this respect WA code, or do I have to re-cut every quantity?
The takeoff doesn't pull a permit for you — that's still on whoever holds the Contractor Registration — but the assemblies match what WA inspectors look for.
How do you handle counting and sizing all openings?
The model reads the plan once, counts symbols against your assembly library, and surfaces the count for review. You override anything that looks off before it hits the quote. For tech work in Seattle, the typical correction is one or two assemblies — not redoing the whole thing.
What about site conditions?
Build the local condition into your assembly defaults once, and it carries forward to every Seattle bid afterward.
