The hiring playbook

How to choose a deck builder in North Plains

Four checks, in order, turn a long list of contractors into a short list you can trust. Work through them before you sign anything.

Step 01

Verify the license is active

Every builder on DeckMath links straight to the official Washington license record. Confirm the number is active and matches the legal business name before you discuss anything else.

Step 02

Confirm insurance and bonding

Ask for current general-liability and workers'-comp certificates. Washington licensing requires a bond, but it is the insurance that protects your property and the crew on your job.

Step 03

Read reviews and call references

Look past the star average — ask past clients about the timeline, the daily clean-up, and how change-orders were priced. Drive by a finished deck from the last year if you can.

Step 04

Get the full scope in writing

A detailed contract — scope, materials named by brand, payment schedule, and firm start/finish dates — protects both sides. Never pay the full amount before work begins.

Washington deck permits, code & climate

Permits

WA permits $250-400. Seattle moss + rain notes.

Frost depth

Footings must reach below the 18″ frost line. A pro sizes piers to that depth — verify it with the ledger & framing guides.

Code baseline

Washington builds to the IRC 2021 deck provisions — guard height, joist span, and footing size all get inspected. Every DeckMath calculator bakes these limits in.

Before you sign

8 questions to ask before you hire

Print this list and bring it to every quote. The answers reveal who runs a real, insured, code-aware operation — and who doesn't.

  • Is your Washington contractor license active, and which class does it cover?
  • Do you carry general-liability and workers'-compensation insurance?
  • Will you pull the deck permit, or is that my responsibility?
  • Which composite or wood brands do you install, and why those?
  • How do you flash the ledger board and size footings for our frost depth?
  • Can you share two or three references from decks you built this past year?
  • What is your written labor warranty, separate from the material warranty?
  • What is the payment schedule, and what milestone triggers each payment?
