"Robert and his crew were great! They were very thorough and professional in completing my deck repair. They offered insight while completing the job to enhance the final appearance. Robert extended his time and completed tasks not included in the original contract without additional compensation. Everyone was very personal, polite and cooperative. I would very highly recommend New - Gen Construction for any deck related projects."

"Mandi and his assistant did a great job on our deck. He replaced the flooring, support post, and other elements that needed repair. He then sealed and stained, two coats each. All work was completed in 3 days! Mandi's professionalism and expert craftsmanship were evident in the final product. We especially appreciated how Mandi discussed details and consulted us about our preferences when changes to the original plan were needed. I highly recommend hiring Mandi."

"Excellent job. The team was meticulous in preparing the deck prior to stain application. They took extra care in removing years worth of debris between planks (and painted over). Also, an excellent job in power washing the house and front walkway. They were courteous and professional."

"I hired Trinium Home Improvement for a deck repair. Mike was highly professional during the whole process, keeping us informed with all the details. The job was done within 3 days, they cleaned after themselves and our deck looks as good as new. I would highly recommend them and would definitely hire them again."

"We had water damage in a room when we were out of town. I hired Joseph and Sons to do the repairs because the pricing was fair. He showed up on time, communicated well and was easy to work with. Angelo worked with me on getting information to my insurance company and found solutions to some ongoing issues we found as the demo started. He also did exterior waterproofing repairs to ensure future water issues would not happen. I had a few extra small requests and he did not nickel and dime us. His workers were very professional and cleaned up at the end of each day. We are very happy with the work and will use on future project."

"They scheduled a 30 minute window for coming to provide an estimate in the afternoon and showed up on time. Our roof repair needs were small, though on second story, steep roof next to the driveway-so something we could not do. First bid from another business had indicated it was a 2 man job and provided a bid. Top Quality HR provided a bid and since there were two of them here and we had some extra shingles, they offered to complete the work on the spot. They fixed the area where shingles were missing and found and tightened up another area that was obviously loosening. In addition, they cleaned the pine needles out of our gutter. We were happy with our experience."

Deck Repair FAQs, answered by experts

Yes, an elevated deck can increase a home's resale value. Homeowners can expect a 65% return on investment from the cost of a second-story deck installation. For example, if you spend $5,000 to install a second-story deck, that deck will add $3,250 to the value of your home.

While the terms deck and porch are often used interchangeably, they are two distinct structures. A porch is a covered structure, usually attached to the front of a home, that offers protection from the elements. In contrast, a deck is an open, uncovered platform, often attached to the back or side of a home. Because porches have a roof, they typically require less maintenance than decks, but both features need regular cleaning and repairs to stay in good condition.

Homeowners should build their floating decks at least 18 inches off the ground. Having it at this height will allow for better airflow underneath and help prevent moisture-related problems like warping or rot. That being said, local guidelines for deck heights may vary depending on where you live.

Yes, deck pier blocks can be used as an alternative to traditional deck footings, particularly for small or low-to-the-ground decks. Unlike poured concrete and buried post footings, deck blocks don’t require digging or pouring. However, their use is regulated by local building codes, and they may not be permitted in areas prone to high winds, earthquakes, or hurricanes. Always consult your local building codes before choosing them for your deck project.

The best base materials for a ground-level or floating deck are typically gravel and crushed stone (also known as landscaping rocks). These options are inexpensive, provide excellent drainage, prevent weeds, and help minimize moisture buildup, which reduces shifting and rotting. For added stability and to evenly distribute the weight, you can use concrete deck blocks or pavers. While more expensive, concrete blocks and pavers offer a sturdier base than gravel or crushed stone alone.
