Drywall Estimating Softwarefor Seattle Contractors
If you're bidding drywall in Seattle, the gap between a job that nets margin and one that doesn't usually comes down to not accounting for ceiling height variations. Drop a plan set in, walk away for 8 minutes, come back to a priced bid you can defend.
What's actually being bid around Puget Sound
500+ drywall contractors 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 drywall contractors 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
High-Rise jobs in Puget Sound tend to share details — once you've priced one, the AI learns your pricing assemblies and applies them to the next.
Green Building work
For green building work specifically, the gotcha is usually Missing bulkheads and soffits. Flag it at takeoff.

Pulling permits in Washington: the license you actually need
Washington won't let you sign a drywall contract without a Contractor Registration, issued by the Washington State Department of Labor and Industries (L&I). 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 drywall contractors 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 sheets for complex room layouts?
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.
