How Much Does Siding Cost in Idaho? (2026 Guide)
For a typical Treasure Valley home in 2026, vinyl siding is the most affordable option installed, LP SmartSide sits in the middle, and James Hardie fiber cement is the premium choice, often costing two to three times what vinyl does. The final number depends on the size of the home and the condition of what is under the old siding. Large two story homes, full trim and wrap work, and rot repair push any quote higher.
Why the three materials price so differently
Vinyl is the lightest material and the fastest install. LP SmartSide is engineered wood, heavier and more labor intensive, with a look closer to real wood. James Hardie is cement based, the most durable against Idaho sun and wind, and the most labor intensive to install correctly. Material is only part of the spread; the labor hours per square foot roughly double from vinyl to Hardie.
What drives your specific quote
The square footage of wall area, the number of stories, how much trim, soffit, and fascia work is included, what condition the sheathing is in underneath, and whether the old siding comes off or gets covered. An honest quote itemizes those pieces. Our full comparison of LP SmartSide vs James Hardie vs vinyl covers how the materials themselves stack up.
A note on who installs it
Siding warranties depend on correct installation, and manufacturers void them over bad flashing and clearance details. Dodd Roofing and Exteriors was voted Idaho's Best Siding Contractor, and we install all three systems across the valley. See our siding page for the products we carry.
