Hardie vs. LP SmartSide: The Ultimate Siding Showdown for the Inland Northwest

Choosing the right siding in the Inland Northwest isn’t just about “curb appeal.” Between our sub-zero winters, heavy snow loads, and the dry heat of July, your home’s exterior takes a beating.

At M&P Quality Construction, we specialize in the two industry leaders: James Hardie (Fiber Cement) and LP SmartSide (Engineered Wood). But which one is right for your Spokane home? Let’s break it down.


1. James Hardie: The Fire-Resistant Powerhouse

James Hardie is the gold standard for fiber cement siding. It’s made from a mix of cement, sand, and cellulose fibers.

  • Why it wins: It’s non-combustible. In areas prone to wildfires or even just for peace of mind, Hardie offers superior fire protection. It also won’t rot, warp, or be eaten by termites.
  • The Look: It provides a classic, heavy feel that mimics wood perfectly but lasts decades.
  • The “Spokane Factor”: It handles the “freeze-thaw” cycle incredibly well because it doesn’t expand or contract as much as vinyl or natural wood.

2. LP SmartSide: The Impact-Resistant Contender

LP SmartSide is engineered wood treated with specialized waxes and zinc borate to resist moisture and pests.

  • Why it wins: Durability against impact. Whether it’s a stray baseball or a heavy hailstorm, LP SmartSide is incredibly tough. It’s also lighter and comes in longer 16-foot planks, which means fewer seams on your house.
  • The Look: It has a deep, realistic wood grain texture that many homeowners prefer for a “warm” Pacific Northwest aesthetic.
  • The “Spokane Factor”: Because it’s more flexible than fiber cement, it’s less likely to crack during the extreme temperature shifts we see in the Spokane Valley.
