44.4 innormal precipitation a year
Rainfall and moisture load in O'Fallon
O'Fallon averages 44.4 inches of precipitation a year, with May the wettest month at 5.1 inches.
Fiber cement's cement-and-cellulose composition is engineered specifically for sustained moisture exposure like O'Fallon sees, unlike a wood-based product left unprotected.
13.5 inches of snow most winters adds its own freeze-thaw cycling on top of the rain.

Fiber cement contractors near O'Fallon, ranked by their Google rating
Review count works like a multiplier here: a 5.0 from a dozen reviewers can still rank under a 4.7 built on a few hundred. That math has nothing to do with licensing, so look up the contractor's license or registration number with the state before you commit.

Fiber cement questions worth asking before you sign

- How will the crew control silica dust when cutting, and what equipment are they using outdoors versus indoors?
- If this home is in a fire hazard zone, is the specific product and assembly rated for it, not just the base material?
- What does the substrate warranty cover, separately from any paint or finish warranty?
- Is this formulation built for {city}'s climate zone, or a generic nationwide version?
