Best siding pros near Belmond, IA

Mildew grows into porous wood, making it more difficult to remove than regular dirt (and more destructive). We suggest using a dedicated mildew and mold fungicide to remove mildew, which is found in any local home improvement store. Apply a dose of the fungicide to the siding and leave to work according to the instructions, usually for an hour or two. Then wash it thoroughly away and scrub the spot again. Repeat the process if necessary. If nothing is removing the mildew stains, you should plan on removing those clapboard planks in time, as their damage could cause future problems.

Siding underlayment varies based on the type of material, but most siding is installed on top of a vapor barrier, a moisture-resistant house wrap, sheathing made from plywood or oriented strand board (OSB), and a layer of insulation sheeting. Having the correct underlayment is a critical part of properly installing siding and will protect your home from water intrusion, structural damage, and energy loss.

The lifespan of siding ranges from 20 to over 100 years, depending heavily on the material, climate, quality of installation, and maintenance.

• Vinyl, Wood, and Aluminum: Typically last 20 to 40 years. Engineered wood may need replacement after just 20 years.

• Fiber Cement: Lasts around 50 years.

• Brick and Stone: These are the most durable, lasting for a century or more with proper care.

The longevity of any siding can be shortened if it's not properly maintained or if damage is not repaired promptly. Regular cleaning is vital. It's time for a replacement when you see widespread damage, signs of water intrusion, or a spike in energy costs.

How long siding takes to install depends on various factors, but averages seven to 14 days for a 1500 to 2000 square foot home. You may have a longer installation timeline if your house is large or architecturally complex, if you have underlying damage beneath the existing siding, or if the weather delays the installation process.
