"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!"

"Just a terrific experience. Hired him to do driveway, and ended up having him paint my house, stain my deck and did other misc. things that needed to be done to list house for sale. Every aspect of the job exceeded my expectations. Would highly recommend him - prices were substantially better than other quotes received. A++++ all the way."

"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 FAQs, answered by experts

Expect to spend around $10,000 to $11,000 to replace a 20-by-20-foot deck. Using high-end materials like composite or exotic hardwoods can drive up the cost, as can custom features and design elements. You can also expect to pay more than average if your deck replacement requires a site evaluation or if you need the work done during the busy season.

Spindles on a deck may also be called balusters or pickets. While not as important to the structural support of the deck as the rail posts, they play a critical role in ensuring the deck is safe to use by closing in large gaps in the railing. For this reason, balusters must be no more than 4 inches away from one another.

A wood deck requires annual cleaning and regular inspections for loose or broken boards, nails, and screws. It should be refinished by applying a stain or sealer every two to three years to protect the wood from water damage, rot, mildew, and sun fading. The exact frequency can depend on the climate and the deck's exposure to sun and moisture. If your deck is painted, it will need repainting approximately every 10 years. Signs that your deck needs refinishing include faded, splintering, or warping boards.

Pressure-treated decking may be worth it if you want a natural, insect- and rot-resistant decking material that will last for decades with proper maintenance. As such, it’s a much better option than untreated pine. Alternative wood decking materials like cedar and redwood tend to be less durable and more expensive. Some homeowners prefer composite decking, which is a low-maintenance alternative to wood but is also more costly.

Yes, adding a composite deck, such as one made from Trex, can significantly increase your home's value. It is a valuable home renovation for recouping costs, with some estimates for return on investment (ROI) ranging between 60% and 70%. More recently, Remodeling's 2024 Cost vs. Value Report suggests a deck addition has an ROI of 82.9%, with an average resale value of nearly $14,600. A new deck makes your yard more functional, enhances the landscape's aesthetic, and can entice prospective buyers. The investment may have a higher return if the deck adds usable square footage to the property.
