What’s Happening With Lumber Prices in Eastern Washington Right Now
If you’ve got a deck, fence, shed, or framing project on the calendar this September, here’s the honest, no-fluff rundown of what we’re seeing at our Airway Heights, Colville, and Kettle Falls yards. Framing lumber has been steady for the past several weeks — grade-to-grade variation exists, but no wild swings up or down. That’s good news if you’re framing a shed or outbuilding right now.
Sheet goods are actually trending in your favor. OSB and plywood have softened slightly week over week, which means if your project calls for sheathing, subfloor, or shed wall panels, you’re catching a reasonably good window to buy.
Pressure-treated lumber is the exception, and it’s worth paying attention to. PT boards — especially ground-contact 2x6s — are firming up faster than the rest of the category, running roughly 3% higher year-over-year. Treatment chemical costs and tighter regional supply are the main drivers, and that trend doesn’t look like it’s reversing before winter.
A Snapshot of Current In-Store Pricing Trends
Here’s a quick category-by-category look at what we’re tracking across our stores. Keep in mind pricing moves weekly, so treat this as a directional guide rather than a locked-in quote — always check with your local Builders Supply team before you finalize a materials list.
2x4x8 Framing Lumber: Steady, with only minor variation by grade.
2x6x8 Framing Lumber: Holding flat compared to early summer pricing.
7/16″ OSB Sheathing: Trending down slightly, week over week.
1/2″ Plywood (CDX): Softening — a genuinely good buying window right now.
Pressure-Treated 2×6 (Ground Contact): Trending upward, the fastest-moving category in the store.
If you’re comparing prices between a national chain’s website and what’s actually sitting on the rack in Airway Heights or Colville, know that online “regional averages” rarely match real-time, in-stock pricing at a local yard. That gap matters more this month than usual, especially on PT lumber.
Why This Is a Smart Window for Deck and Shed Projects
If pressure-treated lumber is anywhere on your materials list — deck framing, fence posts, raised garden beds — the smart move is locking in pricing sooner rather than later. Framing lumber and sheet goods being flat-to-soft gives you breathing room on the structural side, but PT climbing steadily means waiting until October or November could cost you noticeably more per board foot.
This matters even more if you’re in Stevens County, around Kettle Falls or Colville, where the outdoor building season wraps up earlier than it does in the Spokane metro area. A late-fall cold snap can shut down a deck or fence project fast, so getting your quote locked and materials ordered now — while framing costs are stable — helps you avoid scrambling for lumber in a shortened window.
Practical Steps to Take This Week
Get a full materials list before you buy anything. Our staff at all three Eastern Washington locations can estimate board footage for decks, fences, and sheds so you’re not guessing — or paying for a return trip mid-project.
Buy your pressure-treated lumber now. With PT trending upward and showing no signs of softening, ordering this week protects you against further increases before the season ends.
Take advantage of soft sheet goods pricing. If your project includes subfloor, sheathing, or shed panels, this is a good week to buy rather than wait.
Ask about a price hold. We’re offering short-term price holds on pressure-treated lumber quotes right now, so you can plan your project with a firm number instead of a moving target.
Compare local versus big-box pricing carefully. National averages posted online often don’t reflect what’s actually in stock at your nearest yard. A quick call to your local Builders Supply location will usually get you a more accurate number than a website estimate.
Local Service That Actually Knows the Material
We’ve been serving builders, contractors, and homeowners across Eastern Washington since 1979, and the biggest advantage of shopping local isn’t just price — it’s talking to people who actually understand the material. Our team can walk you through grade differences, waste factor estimates, and the difference between ground-contact and above-ground treatment ratings before you ever load a board.
Before you buy, it’s worth asking a few questions: Is this pressure-treated lumber rated for ground contact or above-ground use? How much waste factor should you build into your estimate? Is your local yard carrying enough in-stock inventory for your whole project, or will part of it need to be special-ordered? We answer these questions every day, and we’d rather get it right with you the first time than have you back mid-project short on material.
