"Excellent job. John (the owner) was very responsive and always available. John was able to meet all of our wants and needs. Accommodated a color change after a room was completed with no problem. I have to say I was very impressed with the work, and will have John back next spring to paint the exterior of our home and our deck."

"This review is late but needs to be stated. I have never been treated as well as Jeff and Dave treated us. They were fair, fast, and went above and beyond. The deck was amazing and the office looks like a King’s court. Thank you guys for the service, the craftsmanship, and the friendship. Highly recommend J&D Chris"

Deck Maintenance FAQs, answered by experts

Most building codes require that spindles or balusters on deck and stair railings be spaced no more than four inches apart. This safety standard, often called the '4-inch sphere rule,' is designed to prevent small children or pets from slipping through the railing. A good way to visualize this is that a 4-inch sphere should not be able to pass between two spindles. For the same safety reason, the space between the bottom rail and the deck floor 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 crucial to check your local building codes to ensure compliance before starting your project.

Constant exposure to inclement weather conditions can damage your deck, causing it to fade, warp, or crack over time. Regular maintenance keeps it looking and performing its best. That means giving it a good cleaning and applying a quality sealant or wood treatment to help defend against moisture, sun damage, and everyday wear.

Building a deck without a permit could lead to fines for both the homeowner and the contractor. The exact penalties will depend on your state and municipal building laws. You might also be required to remove the deck and apply for a permit before you can build another. While it might be tempting to skip the permit to save a few bucks, it’ll cost you much more if you’re caught.

When deciding if you should use 2x6 or 2x8 deck joists, consider the size of the deck, joist spacing, and materials. Larger decks, larger-spaced joists, and weaker wood all require more support, meaning they need larger joists. For example, 2x8 redwood joists spaced 16 inches apart can only safely span up to 10 feet and 7 inches. On the other hand, 2x10 southern pine joists spaced 12 inches apart can be as big as 16 feet and 2 inches. If you aren’t sure what size joist is best for your project, speak with your deck builder.

A deck that isn’t attached to a house is called a floating or freestanding deck. These standalone decks are built near ground level, so they usually don’t need deck stairs. Some don’t even require permits. Generally speaking, building a floating deck is faster and more DIY-friendly than constructing one that’s connected to your home.
