Curtis Kapple: Mud and Numbers

By James Florence, Diamond Certified Resource Reporter

EL VERANO — Every kid likes to play with mud, but for Curtis Kapple, this took on a whole different meaning. “My father was a drywall contractor and started teaching me the trade when I was about five years old,” he explains. “By the time I was 10, I was mudding and taping, and by age 14, I was doing finish work. I spent all my weekends and summers throughout high school working full-time.”

After high school, Curtis went to college and studied accounting, but the idea of spending his workdays at a desk didn’t appeal to him, so after graduating, he returned to the trade he knew. “I stuck with drywall for a couple of reasons,” he explains. “Number one, I already had experience, so I could start back up as a journeyman and make a nice income. Number two, I couldn’t sit still when I was that age, so being cooped up in a cubicle all day just wasn’t going to happen.”

Even though he never became an accountant, Curtis’ college education nonetheless gave him an advantage in his professional livelihood. “A lot of drywall contractors are really good at drywall, but they struggle when it comes to the numbers and paperwork,” he says. “My experience with accounting really helped me in that regard because it gave me an edge over my competitors.”

Today, as owner of Kapple Drywall, Curtis says he enjoys the varied and fast-paced nature of his work. “I like the fact that we’re on different jobsites all the time. Usually, we’re in and out within two or three weeks, so we get to see a lot of different homes and meet a lot of different people, which keeps things interesting.”

Born and raised in Marin County, Curtis resides today in Sonoma County, where he appreciates the ample opportunities to demonstrate his professional proficiency. “I like that there are a lot of high-end homes in this area because it provides us with a lot of work,” he says. “Not only is the money good, but the customers are looking for quality, so it really gives us a chance to shine at what we do.”

Outside of work, Curtis engages in a number of active hobbies and pastimes. “I go to the gym regularly and I’m an avid golfer—I actually have a single digit handicap,” he says. “I also love to go fishing and crabbing in my boat. In just the last couple of weeks, I’ve been steelhead fishing in the Russian River and sturgeon fishing in the bay.” Another of Curtis’ favorite pastimes is working with his hands. “I love doing projects, whether it’s working on my house or on one of my boats. It’s like my therapy.”

In his life and career, Curtis espouses the importance of professional integrity. “Everyone makes mistakes, but it’s how you handle your mistakes that determines what kind of person you are,” he asserts. “You don’t walk away from your mistakes—you take care of them. As long as you do that, customers will hire you, because they know that, no matter what, you’re going to make things right.”

When asked the first thing he’d do if he were to retire tomorrow, Curtis says he’d devote more time to the activities he currently enjoys. “I’d still go to the gym, golf and go fishing. I’d also probably do some more traveling.”

Frequently Asked Questions
FAQs for Local Drywall Contractors

Q: Why choose a Diamond Certified drywall contractor?
A: Diamond Certified helps you choose a drywall contractor with confidence by offering a list of top rated local companies that have passed the country’s most in-depth rating process. Only drywall contractors rated Highest in Quality and Helpful Expertise® earn the prestigious Diamond Certified award. Most companies can’t pass the ratings. American Ratings Corporation also monitors every Diamond Certified company with ongoing research and ratings. And your purchase is backed by the Diamond Certified Performance Guarantee, so you’ll feel confident choosing a Diamond Certified drywall contractor.

Q: How can I be sure that I am hiring a good drywall contractor?
A: Choosing a Diamond Certified drywall contractor will help ensure that you are getting a contractor you can trust. This is the best way to hire a good drywall contractor and avoid any scams. If you are unable to hire a Diamond Certified drywall contractor in your area, then look for a local drywall contractor that has worked for someone you know. Be sure to call references of the drywall contractor you are considering. Also, check with any organizations the drywall contractor is a member of, as well as local consumer reporting agencies and the CSLB to see if the contractor has any complaints against their record.

Q: What does the backing on drywall do to prevent fire?
A: Backing on drywall is constructed in such a way that it should remain stable for an hour or longer in the unfortunate event of a fire. Checking for backing is part of the inspection process and must be applied in order to pass on certain drywall areas. Backing adds strength to drywall. When a fire hose is spraying water on the drywall, the drywall should be able to keep its structural integrity for sixty seconds of direct spray.

Q: When my drywall is being installed, will there be dust?
A: Yes, dust from drywall can be very heavy. Your contractor will do everything possible to protect your home from the dust but, unfortunately, dust is a part of drywall installation. You will want to keep your air conditioner and heater turned off while the drywall is being installed. Your drywall contractor may bring in fans to help with the ventilation during the drywall process.

Q: Is hanging drywall a difficult job?
A: Hanging drywall is the most physically demanding part of installing drywall. The drywall installation requires patience and it is very demanding work. Besides hanging the drywall, there is the application of tape and mud. You want a drywall contractor that can do the difficult work but also has an artistic eye to do a great job.

Q: Do you need to use greenboard in the bathroom?
A: Yes, greenboard is necessary in any room that has regular use of water such as the bathroom and laundry areas. Greenboard is moisture resistant. Greenboard doesn’t work in areas like showers or bathtub walls. For those areas, you need something that is waterproof not just water resistant.

Q: Is sheetrock fire resistant?
A: Yes, sheetrock or drywall is fire resistant. However, it is not fireproof. There are different levels of fire resistance with sheetrock. Your drywall contractor can recommend the best type of drywall fire resistance for your project.

Q: Can I get an estimate on drywall repair over the phone?
A: Yes, you can probably get an estimate over the phone. However, you will more than likely be given a minimum charge which may not be accurate. Every job is unique and the only way to get a true estimate is for the professional drywall contractor to see your drywall project area and measure it.

Q: Should I use sheetrock or drywall?
A: Actually, sheetrock and drywall are the same thing. They may also go by the names of gypsum board or wallboard. They are all used for drywall projects and they are made of the same material.
