"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

Deck boards should be spaced no more than three-eighths of an inch apart. This is enough space to allow water and small debris to pass through without collecting on the surface, but not enough to create a tripping hazard. Certain materials, like pressure-treated wood, shrink over time, so they may need less space at installation.

Be careful when choosing a product to help you remove ice from your wood deck. Never use sand, gravel, or salt, since these items can damage and scratch the wood. Instead, look for chemical de-icers that are marked as safe for wood decks or use hot water to melt snow and ice.

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.

Local building codes don’t specify the number of steps a deck can have before a railing is required, mainly because stair height varies widely. Most areas require decks 30 inches or higher to have a railing. While not exact, that roughly equates to four to seven steps.

If you want to make a deck cleaner from products already in your home, there are various options. The most common is to use a gentle blend of 1 gallon of warm water and 2 tablespoons of ammonia-free dish soap. You can also mix water with distilled vinegar. Sprinkling on some baking soda can help to remove mold and mildew. You can add oxygen bleach (but never damaging chlorine bleach) to the water and ammonia-free dish soap solution for something a bit stronger.
