How much have building materials gone up in 2026?
Overall construction input prices are up 10.5% over the past year (July 2026). Below is the 12-month change for the materials behind common home projects, straight from the U.S. Bureau of Labor Statistics Producer Price Index — the same numbers contractors watch when they set quotes.
| Material | Used for | 12-month change |
|---|---|---|
| Steel mill products | beams, rebar, fasteners | ▲ +31.9% |
| Iron & steel | structural steel | ▲ +17.6% |
| Inputs to construction industries | overall construction inputs | ▲ +10.5% |
| Lumber & wood products | framing, decking, trim | ▲ +10.1% |
| Nonferrous metals | copper wire & pipe, aluminum, flashing | ▲ +6.2% |
| Heating equipment | furnaces, boilers, HVAC | ▲ +3.9% |
| Concrete ingredients | foundations, driveways, patios | ▲ +3.7% |
| Plastic construction products | PVC pipe, vinyl siding, fittings | ▲ +3.6% |
| Construction machinery & equipment | installation equipment | ▲ +2.7% |
| Paints & coatings | interior & exterior painting | ▲ +0.6% |
| Gypsum products | drywall | ▼ -0.4% |
What this means for your project: when a material spikes, quotes for projects that lean on it move first. Steel-heavy work (structural, fencing, roofing fasteners) and anything copper tracks these indexes closely; lumber-driven jobs (framing, decks) follow the wood line. A flat or falling material isn't a discount — labor is usually the bigger half of a bill (see construction labor cost by state).
Method & source
Figures are the year-over-year change in the Producer Price Index (commodity data, not seasonally adjusted) published by the U.S. Bureau of Labor Statistics, for July 2026. We track the commodity indexes that map to home-project materials and automatically exclude any series with a one-month discontinuity (a BLS recoding artifact) so the trend stays honest. The PPI measures prices producers receive, which lead retail and contractor pricing. See our full methodology. Data pulled 2026-09-01.
