"This was the first time we had our deck power washed and stained by Rob. It hasn't looked this good since it was built. He also replaced some broken lattice work and everything he did was in a very skillful manner. We've already asked Rob to do other jobs for us around the house. We highly recommend him."

"Hector and Moises were excellent! Hector came with one other of their crew and assembled my permanent gazebo. I have stone pavers and they were very careful in cutting them and digging Deep enough to establish a good anchor. They even installed railings for my back stoop. I would highly recommend them! Clean... affordable and professional."

"Every person Iâ ve come into contact with at Sebonac has been friendly and professional. For me personally, one of the most important things, and what Iâ ve had problems with in other companies, is communication. These guys pick up the phone when I call, and if they canâ t they immediately call back. Iâ ve worked with a lot of different companies through the years and their prices are fair and just overall I really like their attitude when it comes to problem solving or working through any issues I have. There good people and do good work."

Deck Maintenance FAQs, answered by experts

Composite decking requires a solid foundation, substructure, or subframe to ensure stability. This base is typically composed of posts, beams, joists, and footings. The frame's joists can be built from various materials like composite, plastic, timber, or metal, as long as the base can support the deck's weight without shifting. A professional deck builder might recommend installing the frame on a solid concrete base for added durability. The final design and materials for the substructure will depend on your budget, the type of deck, and environmental conditions.

Yes, pressure washing a wood deck can be a good idea as it effectively lifts ingrained dirt, mold, and mildew, improving the deck's appearance and longevity. However, it must be done carefully, as it's easy to damage the wood, especially softwoods. To pressure wash safely, use a lower pressure setting and a wide, 40-degree fan pattern nozzle (often white). Keep the nozzle at least a foot away from the wood surface and maintain constant motion, avoiding hovering in one spot to prevent gouging.

There are several methods for attaching stair stringers to a deck. The best way is to bolt the stringers to the deck joists using three carriage bolts in a triangular pattern. This method offers the sturdiest fit for stairs that won’t budge. Alternatively, attach the stringers to the deck rims using lag bolts or to the posts using adjustable slope hangers.

Cutting the boards directly is one of the fastest ways to remove deck boards with hidden fasteners. Mark two parallel lines that are one-third of the total measurement on both ends and cut out the centerpiece. Then, remove the end of the board that doesn’t have a fastener. Finally, pry open the fastened side and pull it up to pop out the screw or access the fastener. This also allows you to salvage portions of boards for other projects.

Composite decking requires a solid foundation or substructure for support. This base is typically a frame composed of posts, beams, joists, and footings. The frame can be built from various materials, such as composite, plastic, timber, or metal, depending on your budget, deck type, and environmental conditions. For maximum stability, a professional deck builder may recommend installing this frame on top of a solid concrete base. It is best to discuss the most suitable substructure design and materials for your specific project with a professional.
