"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

It depends on the type of wood. The average cost to build a deck out of pressure-treated lumber is $15 to $25 per square foot, but more affordable varieties such as bamboo and cedar cost less at around $3 to $10 per square foot. However, when comparing the cost of vinyl decking versus wood decking, it’s important to also consider ongoing maintenance costs. For example, most woods require regular sealing to keep them protected against weather and rot.

For a 12x20-foot (240-square-foot) deck, you can expect to pay between $7,200 and $14,400. This cost is based on a general price of $30 to $60 per square foot. The final price will depend on factors such as the decking material, design complexity, deck type, location, and local labor costs. Keep in mind that add-ons will increase the total; for example, adding an under-deck drainage system to a deck of this size could cost an additional $7,700.

Yes, adding railing to a deck is a great way to improve safety and your home’s aesthetic appeal. Railings can be constructed from wood, metal, or composite, and there are plenty of choices regarding design and style. Always consult local building codes before starting any building project—there are often requirements regarding spacing and height that can differ slightly from place to place.

For the best results, stay off of your deck for at least 48 hours after sealing it. Giving the sealant at least two full days to cure ensures it can fully penetrate the wood, giving you the most protection from sun and weather damage later on. Walking on the deck too soon can prevent it from properly curing and cause your deck to weather prematurely.

Rot loves moisture, so deck rot typically impacts the parts of a board that stay wet. This includes the underside of boards, in addition to support posts and joists. However, any part of a board can rot, given the right conditions.
