"Johnston General Contracting did very fine work on power washing and sealing my deck. The deck looks great. While he was late on the first day of the job the second day he was right on time. I would recommend this company. The only negative would be that the price seemed on the expensive side."

"The whole company impressed me very much did exactly what I wanted much faster than I expected. Very kind and personable, perfectly power washed and stained a pergola, picnic benches, table, swing, and two other decks. Also replaced railings and floorboards all for a very reasonable price. Very highly recommended!"

"I had a front and back porch project underway, when my guy cancelled and recommended Jeremiah to take over. Not only did he price it better, but he finished in under a week what I thought would take months. True, hard working company that will give you the best service, whenever. Great crew!"

Deck Maintenance questions, answered by experts

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.

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.

Yes, but ensuring the deck has a solid foundation with adequate footings is critical before building, as the weight of a sunroom will put significant pressure on the structure below. Even if your deck is properly constructed, it may not be able to handle the extra weight. While some basic, lightweight, prefabricated sunrooms can sit on a deck with a strong existing foundation without additional supports, in many cases, the foundation and joists will need reinforcement. It is always best to have a structural engineer perform an inspection to evaluate the deck's quality and structural integrity. A professional can help you decide if reinforcement is sufficient or if it's better to tear down the deck and start over.

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.

The overhang, or nosing, of deck steps is another area that will be covered in building code requirements. The noses on your deck steps should have a minimum overhang of ¾ inch. For safety, usability, and code compliance, the nosing of deck steps should not extend past 1¼ inches.
