"They did an excellent job. They initially misquoted the price on the low side but the president said they would go ahead and honor that price. They were very responsive to anything needed before and after the job was done. They stand behind their work and in my opinion are an exceptional company. I would highly recommend them and I would definitely use them again."

Siding FAQs, answered by experts

To calculate how much siding you need for exterior walls, first measure the height and width of the rectangular walls. For the triangular gable walls, measure the width and then the height from the ground to the tallest gable point.

  • For the rectangular walls, the calculation is: length x height

  • For the triangular gable walls, the calculation is: (length x height) / 2

Once you add these up, include an additional 10% to account for any wastage.

Caulking should be re-applied roughly every five years. It's natural for a home to settle and separate caulking from joints, so it's a good idea to assess the home every two years. A consistent siding maintenance schedule will help you see if the caulking is needed and address any potential issues before they occur.

Vinyl, brick veneer, stucco, steel, stone veneer, and composite siding are popular alternatives to wood siding. Which siding material is best for your home boils down to your budget, aesthetics, lifestyle, and climate. For example, stone veneer offers a timeless charm and is low maintenance but may have too high of a price tag. Meanwhile, some homeowners love vinyl siding for its low cost, while others dislike it for its appearance and shorter life span.

The clapboard exposure, also called the reveal, refers to the amount of clapboard visible in the siding. Clapboards always overlap slightly, but some overlap more than others. The exposure is the vertical measurement of the board that remains visible as the clapboard is installed.

When repairing clapboard siding, it’s important that you match the exposure of your current clapboards. You may want to take a measurement of the specific exposure on your siding for reference in repairs.

There should be small gaps between your roof and the walls of your home, and other buildings. These small gaps let building materials shift, expand, and contract with weather and other outside forces, and they prevent moisture from wicking down walls from roofing and gutter systems. Without these strategic gaps, your home’s exterior and its finishes can sustain water damage, decay, peel, delaminate, and crack. However, there is a fine line between a smart gap and a problematic gap—all  gaps should be small, intentional, and covered or filled in with foam insulation to prevent pests from using them as access points.
