"Our roof replacement with Ocean Seven Builders went better than we expected. Ron was easy to talk to and always got back to us quickly when we had questions. The workers were friendly and worked fast without cutting corners. Everything was done in a reasonable time, and the house was left clean afterward. We’re happy with how the new roof turned out!"

Siding questions, answered by experts

Stucco is considered a type of cladding because it includes a built-in ventilation layer, a weatherproof membrane beneath that, and, often, a layer of insulation to improve building efficiency. The multiple layers of stucco—the scratch coat, the brown coat, and the finish coat—also create a more complex building membrane, so it’s more accurate to call it cladding. However, homeowners and contractors alike refer to stucco as siding.

Look and feel for signs of damage after a hail storm. On vinyl siding, there will likely be cracks or holes. If you have steel or aluminum siding, look for dents and cracked or chipped paint. For wood and fiber cement boards, dents are the most common sign of hail damage.

Vinyl can withstand many different cleaning methods, but there are two things you need to be wary of. First, particularly harsh chemicals will damage your vinyl siding and reduce its lifespan. Second, be careful about pressure washing your vinyl siding. Vinyl can resist powerful washing damage more than softer siding like wood, but high levels of pressure can still crack it. Use the lowest level of pressure for power washing vinyl, or hire a siding professional to do it.

Some homeowners use caulk on the edges of clapboard siding to help seal it. However, this method invites new problems. With so many gaps sealed, clapboard siding is often unable to drain properly and moisture from rain or other sources can build up inside. This can lead to rot and other issues over time. When repairing clapboards, it’s best to avoid caulking the final product. The exception is trim around windows and doors, which should be caulked to avoid moisture problems.

The necessary frequency of mold cleaning in your home will depend on several factors, including the climate, the presence of moisture sources, and the type of siding. It's generally recommended to inspect your siding regularly and clean any mold growth as soon as it appears to prevent it from spreading or causing damage. If you’re not sure how often you should clean mold off siding, you can always contact a siding contractor near you to consult on what maintenance schedule will work best for your home.
