Professional installers typically recommend caulking between siding boards, but it depends on the material. With Hardie board and fiber cement siding, manufacturers don't recommend adding caulk because it can trap moisture in the joints or discourage flexibility in fluctuating temperatures. Consult your local siding contractor about caulking best practices before adding any to your home’s exterior.
Dents, rust, loose panels, and weather-related damage are common problems requiring repair.
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.
You cannot install clapboard siding on a bare, unprepared surface. Clapboard siding requires a clean, sturdy base made from plywood or similar materials, sometimes called backerboard. Then, it needs an underlayment or sheathing, a moisture membrane to help protect the exterior wall.
Note that sometimes clapboard siding is caulked as it’s installed for additional protection. We don’t suggest this: Caulking the siding can trap moisture inside the clapboards and lead to moisture damage over time. The siding needs some space to “breathe,” especially in rainy weather.
Yes, you can install siding over stucco, but it's crucial to ensure the stucco is in good condition first. Before proceeding, inspect the stucco for any signs of damage, leaks, or mold growth. If you discover water damage, mold, or have ongoing leak issues, it's recommended to remove the stucco completely. This step prevents future problems like mold and pest infestations and allows a professional to repair or replace any damaged sheathing underneath. If the stucco is sound, the installation process involves attaching furring strips to the wall's framing directly through the stucco. The new siding is then installed onto these furring strips. A professional may also need to adjust window and door openings to prevent them from being recessed behind the new siding, which can cause aesthetic issues and create potential leak points.
