New siding is one of the larger investments you’ll make in your home, and it stays on the house for decades — so it’s worth taking the time to choose well. Two of the most common options we install are James Hardie fiber cement and CertainTeed vinyl. Both are good products from respected manufacturers. The right one for you comes down to your home, your budget, and what you care about most. Here’s an honest comparison to help you decide.
What fiber cement siding is (James Hardie)
Fiber cement is a blend of cement, sand, and cellulose fibers pressed into rigid boards. James Hardie is the best-known name in the category, and we’re a certified installer. It’s heavy and solid, holds paint well, won’t melt or warp in heat, and stands up to wind and impact. It’s also non-combustible, which some homeowners value.
What vinyl siding is (CertainTeed)
Vinyl is a PVC-based panel, and CertainTeed is a well-regarded brand we’re certified to install. It’s lighter, more budget-friendly, and its color runs through the whole panel rather than sitting on the surface as paint — so scratches are far less noticeable. Modern vinyl has come a long way in both looks and durability.
How they hold up in New England weather
Our freeze-thaw cycles, wind, and moisture are hard on any exterior. Fiber cement is dimensionally stable and shrugs off temperature swings, though proper installation and paint and caulk upkeep matter. Quality vinyl handles cold and moisture well and never needs painting, but lower-grade vinyl can grow brittle over many hard winters — one reason the product grade and the install both matter.
Appearance
Fiber cement can be painted any color and convincingly mimics wood grain, which is why it’s popular on historic and higher-end homes. Vinyl offers a wide range of factory colors and profiles at a lower price point. Both look great when installed cleanly; the right look is genuinely personal.
Maintenance
Vinyl is close to no-maintenance beyond the occasional wash. Fiber cement asks a little more over the years — repainting eventually, and keeping caulk lines sound — in exchange for its longevity and finish.
Cost
Fiber cement generally costs more, both for the material and the labor, since it’s heavier and more involved to install. Vinyl is the more affordable route. Neither is truly “cheap” when it’s done right, and we’d rather be upfront about that than surprise you later.
Installation matters more than the brand on the box
Here’s the part homeowners don’t always hear: even the best siding will fail early if the moisture barrier, flashing, and fastening aren’t done correctly. Water management behind the siding is what protects your walls. Being certified to install both James Hardie and CertainTeed means we’re trained in each system’s details — and we treat that layer you never see as seriously as the one you do.
