"Stuart Riensche and his crew did an excellent job and were a pleasure to work with. I would highly, highly recommend this company to anyone. He runs a tight ship. We were soo impressed with the quality of work! Great attention to detail. Such a beautiful job and done on time, on budget without any negative suprises. Can't say enough good things about these guys. And their pricing was very competitive. Stuart got back to us quickly and once we accepted the bid, he scheduled us. The project start date was a couple of months out, and they started right on schedule. Our home hadn't been painted in 15 years ago and was starting to look like it needed to be done again. My husband had used a sprayer and only put on a single coat at the time. When they pressure washed our house, quite a bit of loose paint came off, down to the bare wood. That meant that the primer paint layer that was needed was more extensive than they had planned. They did a great job making sure the bare wood was all primed, and then painted 2 coats of top quality paint. All the lines are crisp and so professional. We realized after they started that we also wanted to have the deck painted, and they were able to do that too, at a very good price. Stuart and his team met and greatly exceeded our expectations! Really great company."

"I’ve used Evergreen for a few projects mostly outside. They do a super job of managing their work site, being on time and within budget. Our deck stain job, one cedar & one Ipe, turned out beautiful and they gave me great advice on keeping them in good shape. I also used them for refinishing 45 year old wood floors. We had no idea how much they needed Nate from Evergreens’ touch. The floors turned out beautiful and significantly increased the resale value of our home. It took an extra coat of stain and finish but it was worth the effort. He communicated profess to me each day so when I arrived back at the house there were no surprises except how great the floors look! As usual, Nate and the guys exceeded our expectations."

Deck Maintenance FAQs, answered by experts

Most building codes require that railing spindles (also known as balusters) on decks or stairs be spaced no more than four inches apart. This safety standard is often called the '4-inch sphere rule,' which means a sphere with a 4-inch diameter should not be able to pass through the opening between balusters. This rule is in place to prevent small children and pets from slipping through the railing. For the same reason, the space between the bottom rail and the deck or floor surface should also be no more than four inches. As a general guideline, professionals often install three balusters per foot of railing. However, since specific requirements can vary by location, it is essential to check your local building codes to ensure compliance before starting your project.

You can use a few different tactics to prevent your deck gate from sagging. Aside from using strong, rot-resistant woods, introducing a diagonal element—such as a tension rod or solid piece of wood to act as a brace—across the gate will offer better support. You can also use rigid joists to prevent the gate from sagging.

Typically, most residential wooden decks are designed to support approximately 40 pounds per square foot, including the deck’s weight and any items placed on it. While this is fine for typical use, it is usually not enough to hold the weight of a hot tub filled with water and people. To safely support a hot tub, your wood deck will likely require reinforcement. Therefore, it’s best to have a contractor or a structural engineer assess it before hot tub installation.

Deck skirting shouldn’t touch the ground, especially if you have a wood deck, which is vulnerable to moisture. Ideally, you should leave at least 3/4 of an inch of space between the deck skirting and the ground for more ventilation. Pros also recommend that you incorporate about 1 square foot of space for ventilation for the underside of the deck to every 150 square feet of decking. Proper ventilation prevents mold growth and rot that can damage your deck.

Although composite decking is extremely durable, it’s also susceptible to extreme heat. Prolonged exposure to sunlight can cause fading, warping, and cracking. Composite also retains heat more than wood, which makes it dangerous to walk on in the summer. You can help prevent heat damage by only building with composite in shaded areas or using rugs to cover the hottest spots.
