Framing lumber has become steadily more expensive across New York and New Jersey for the past two quarters. There was no single major price increase or announcement. Instead, suppliers raised prices in a series of smaller steps. Taken together, those increases have significantly changed the cost of framing a wall.
The data below comes from supplier invoices processed by CostCrunch in the first eight months of 2026. These are prices that contractors actually paid on active construction jobs, not advertised prices, estimates, or forecasts.
Key Takeaways
- Framing lumber has increased by roughly one-third since March. The most commonly purchased 2x4 increased from $5.90 to $7.90 per board, a 34% increase in five months.
- The increase affects more than one type of lumber. Every framing product in the data increased between 21% and 42%, covering multiple board sizes and types of wood.
- Prices can vary significantly even on the same day. One 2x4 had a 21.5% spread, ranging from $6.50 to $7.90, in a single day.
- Prices have not yet shown a clear reversal. August was the most expensive month in the data, while the largest individual increase, 42%, occurred in July.
- Construction budgets based on spring prices are now roughly one-third too low for framing lumber. A project priced using March lumber costs but built using August prices would absorb a substantial increase that was not reflected in the original budget.
Prices Increased in Steps
The increase did not happen smoothly over time. Instead, lumber prices tended to remain at one level for several weeks before jumping to a higher level and remaining there.
That pattern can make the increase difficult to notice when looking at individual invoices. But when the invoices are viewed together over several months, the trend becomes clear.

The Standard 2x4
The most common 2x4 in our data is a 10-foot board. Its price per board changed as follows:
- March through early June: $5.90
- June: approximately $6.50
- Later June: approximately $6.90
- July onward: approximately $7.90
The result is a move from $5.90 to $7.90 per board, or 34%.
Importantly, the old and new prices did not always replace each other immediately. For example, $6.50 lumber was still being billed on July 1, the same day that $7.90 lumber first appeared. This means contractors were sometimes paying different prices for essentially the same type of material depending on the specific order.
August is only measured through August 18, but it is already the most expensive month in the data.
Why Monthly Averages Can Be Misleading
May is a good example of why simply looking at the average price for a month can hide what is happening.
The average price in May decreased, but this did not represent a broader decline in lumber prices. Instead, one unusually large order was billed at a significantly lower price, pulling the monthly average down.
In other words, the volume and timing of individual purchases can have a major effect on the reported average price. Looking at individual transactions and price levels provides a better picture of the underlying trend.
The Increase Is Broad-Based
If only one type of lumber had become more expensive, the increase could be explained by a problem specific to that product.
That is not what the data shows.
Prices increased across different board sizes and types of wood. The increases observed include:
| Product | Period Compared | Price per Foot | Increase |
|---|---|---|---|
| #3 2x4, 16 ft Green Hem Fir | Jun 21 – Jul 15 | $0.41 → $0.58 | 42% |
| 2x8, 12 ft Green Hem Fir | Jun 8 – Jun 22 | $1.41 → $1.70 | 21% |
| 2x10, 12 ft Green Douglas Fir | Apr 21 – Jul 15 | $1.75 → $2.19 | 25% |
The important point is that the increases are not limited to one particular board or one particular type of wood.
Green lumber also increased significantly. That matters because contractors cannot necessarily avoid the increase simply by switching from a less expensive green product to another grade. Green lumber has a higher moisture content and changes as it dries, so it is also not a direct substitute for kiln-dried material.
Price Variation Is Becoming a Problem Too
The increase in the average price is only part of the issue.
The bigger challenge for contractors and estimators may be that the price of the same material can vary significantly depending on when and how it is purchased.
For example, on one day in July, one 2x4 had a 21.5% spread, ranging from $6.50 to $7.90. The difference between the lowest and highest price was $1.40 per board.
That creates a problem for construction budgeting.
If lumber had one stable market price, an estimator could use that number when preparing a project budget. But when prices vary substantially between individual orders, a single "market price" becomes less useful.
Board Lengths Also Have Different Prices
Even different lengths of the same lumber can have different costs per foot.
During the week of July 8–13, the following prices were recorded for kiln-dried Douglas Fir 2x4s:
Source: CostCrunch spend data. Billed July 8 to July 13, 2026.
The 10-foot board cost 13% more per foot than both the 8-foot and 16-foot boards.
Three weeks later, however, the 8-foot board had increased by 15%, eliminating that advantage.
This means there is no single length that can always be assumed to be the cheapest on a per-foot basis. The economics can change from one order to the next.
What This Means for Construction Budgets
The data points to two separate risks for contractors.
First, the overall price of lumber has increased substantially. A contractor who priced a project using March lumber costs could now be paying roughly one-third more for the same basic framing material.
Second, the exact price is difficult to predict. Lumber prices can differ between orders, board lengths, and purchase dates. This makes it harder to simply add a fixed percentage to an old estimate and assume the resulting number will be accurate.
For projects where framing lumber represents a significant portion of material costs, this can directly reduce the contractor's expected profit.
A project that was profitable when it was bid in March can become substantially less profitable if construction does not begin until July or August and the lumber budget is not updated.
Bottom Line
The data does not show one sudden lumber-price spike. It shows something potentially more important for contractors: a sustained upward reset in the cost of framing lumber, combined with unusually large differences between individual purchases.
Since March, the standard 2x4 has increased by 34%, while other framing products have increased by 21% to 42%.
For contractors, builders, and estimators, the practical takeaway is straightforward: spring lumber prices should not be assumed to represent current costs. Budgets need to account not only for higher average prices, but also for the possibility that the actual price paid on a specific order can vary significantly from the expected market price.
