"I had siding replaced and very displeased with the entire process. The crew did a poor job for what I paid and have already had to be back out here 3 times in a month to fix their mistakes. Crew cheif never checked the work to determine if the quality was up to the company standard. The crew left the property a mess with my belongings scattered around the yard. They had leftover pieces scattered as well. The craftsmanship and quality was aubpar for the price. No care for the property. Damaged driveway, roof, windows, and garden bed. Chalking already cracking. Large gaps in the siding. Siding already buckeling. Seams not together. Asked to speak to a manager or supervisor multiple times and still no response. I was promised certain tasks at point of sale that company will not follow up on. Over all this company treats their customers as money and gets in and out with little oversight or quality check. I am very displeased with the product I got for the money I paid. Will never recommend."

Siding questions, answered by experts

The most significant benefit to mixing siding styles is the visual appeal and intrigue you can create. Multiple colors or textures will make your home stand out, boosting curb appeal and home value. Mixing siding styles also lets you take advantage of the high resale value of stone without having to pay the high cost of covering your entire home with it. Coupling stone and vinyl means pairing affordability and value. Plus, you’ll often only have to pay for a partial siding replacement when it comes time to replace one of the materials.

The living space of a home doesn’t correlate directly with how many square feet of siding you’ll need, but on average, a 2,000-square-foot home will need 1,700 square feet of siding or 17 squares of siding. Your siding measurements will vary depending on the layout of your home, the number of stories, the size of your doors and windows, and even your roof style.

Wood clapboard siding needs frequent sealing to keep it in top condition—likely every two to three years. A sealant helps protect it from both moisture and sunlight damage. Your weather and climate will affect how often you need to seal the siding, but the pros recommend sealing it every couple of years. More durable woods in milder climates may not need to be sealed quite as often.

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.

Yes, you can shou sugi ban existing siding, but it might pose a hazard to wooden structures, shouldn’t involve treated wood, and must be done by a siding professional. You can not char wood on a house without first removing the boards, so it’s a more complicated replacement project than other siding types.
