Made from cement, wood fiber (cellulose), sand and other components, fiber cement siding can be manufactured to have the realistic appearance of wood, stucco or masonry. Promoted as environmentally friendly because it requires fewer trees, fiber cement siding won't burn, never rots, extends the life of a paint job and usually is warranted for 50 years. This is a relatively new product that's gained in popularity in recent years. Its main drawback is that it's heavy to lift, needs specialized cutting tools and installation is often a dusty process.
Typical costs:
Fiber cement siding comes in a range of styles and grades of quality. Construction industry estimates for having it installed range from $4.50-$9 a square foot, or $5,600-$11,250 for 1,250 exterior square feet. However, a nationwide survey by RemodelingOnline.com pegs the average cost for an upscale project replacing 1,250 square feet of existing siding with high-quality fiber cement around $13,000-$14,000, or $10 -$11 a square foot.
Do-it-yourself materials (including goggles and dust masks) run about $1,200-$2,000 for 1,250 square feet, plus $200-$500 for specialized cutting tools (either power shears, which create very little dust, or a dust-collecting circular saw with a fiber cement blade)."
What should be included:
A high-temperature pressurized-steam curing process used during the manufacturing of fiber cement siding makes this product exceptionally strong and stable. However, fiber cement siding is more difficult to cut than real or engineered wood. Installers must use special equipment to cut it, and must wear masks and goggles as protection against harmful dust. Plus, fiber cement siding weighs about 1.5 times as much as wood siding. If installed correctly, fiber cement siding is more durable than wood, vinyl and aluminum, and the only maintenance required is occasional power-washing. However, incorrect installation can cause moisture problems, including mold and rot in the sheathing or structural supports. The Portland Cement Association provides an overview.
Before getting quotes or buying materials, check with the local planning department to see if there are any local regulations governing types of siding, especially if the neighborhood is in a historic district or overseen by a homeowners association.
Additional costs:
If a home's existing exterior walls haven't been properly maintained, there could be water or weather damage requiring additional carpentry or other repair costs. The amount will depend on the extent of the damage.
Discounts:
Find nearby neighbors who also want fiber cement siding installed, and negotiate a reduced price for multiple projects in the same area. Price estimates may be lower during the off-season, when contractors are often looking for work.
Shopping for fiber cement siding:
Major manufacturers include James Hardie, Certainteed, Cemplank and Nichiha. Contractor referrals are available from the manufacturers. It's important to choose someone with experience installing fiber cement siding.
Get several estimates, making sure what is (and isn't) in each quote; understand whether all prep and clean-up work is included. Request and check references. Ask to see a completed project; joints should be neat and evenly caulked. Ask about the contractor's length and type of experience. Be sure the contractor is properly bonded, insured and licensed in your state. Check for any complaints with the Better Business Bureau.
Purchased all materials, rental of scaffolding and paid labor on hourly basis. Had stucco removed and replaced with Hardie Plank siding and MiraTec trim boards. Siding contractors estimates ranged from $20k and up.
Purchased all materials. Removed all metal siding, osb over cedar siding, house wrapped, retrimmed, and hardie from 42" up. House is 100 years old. Hardie imitates cedar 5" lap beautifully! Did ourselves. Couldn't be happier!!
Price includes siding for 1300 sq ft house with a 5 3/4 inch reveal. Plus James Hardee 4 inch trim boards. 2 fiber cement mitre saw blades for cutting the trim, a fiber cement electric shears, hot dipped galvanized nails and a set of lap siding brackets to hold the siding in place during nailing. Don't use a nail gun--they damage the siding. Use a hammer. Don't buy the cheap fiber cement siding--it may not be as pliable as say, James Hardee, and it may be subject to cracking and pre-drilling as with slate. James Hardee is pliable enough where you do not need to predrill in most spots (except butt joints), nor will break easily if it bends. And at $10 per board you don't want to waste any.
