"I had an outdoor playground set. Adrian was professional and hard-working. Great communication and he brought all the required tools and equipment. He showed up first thing in the morning on a short notice and it was all done before the end of the day. The assembly looks great and I know the kids will love it!"

"We hired I Construction to replace 26 year old decks (4). Danny (owner) and his crew did a wonderful job. His crew was on time each day and cleaned up at the end of each day. Danny came to check on the job every day and sometimes more than once. He also "mucked in" when necessary. Definitely an ethical company to work with."

"Jessy and his team are hard-working, trustworthy, and extremely knowledgeable. They did so many different projects. Cleaning out the attic: re-routing the wires, installing bathroom fan vents, replacing filthy insulation, installing light. Installing a French drain in a horseshoe pattern going all around the house and out to the street (tested with heavy rain and it works GREAT). Mounted mirrors, medicine cabinets, shelving and it was always level. Repaired the leaking pipes under my house and hooked up water to the refrigerator ice maker. I got price estimates for some of these projects from people like â Attic Specialistsâ and the price from others was double."

Deck Repair FAQs, answered by experts

The proper and most comfortable height for a deck stair riser, also called a step, is between four and seven inches. A height of seven inches is often considered ideal for a strain-free step that minimizes the risk of trips and falls. While it is possible to have risers up to 12 inches, this height can be challenging for children, pets, or individuals with mobility issues. For optimal safety and comfort, pair a seven-inch riser with a tread depth (or run) of at least 10 to 12 inches. Always check your local building codes, as they may have specific requirements that differ from these general recommendations.

Typically, most residential wooden decks are designed to support approximately 40 pounds per square foot, including the deck’s weight and any items placed on it. While this is fine for typical use, it is usually not enough to hold the weight of a hot tub filled with water and people. To safely support a hot tub, your wood deck will likely require reinforcement. Therefore, it’s best to have a contractor or a structural engineer assess it before hot tub installation.

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.

You do not have to dig footers for a deck as long as it meets local code and holds up to weather in your area. If you live somewhere that experiences high winds and earthquakes, you may need to dig for your deck posts. Deck blocks, post anchors with base plates, and helical pile systems are the three no-dig deck post options you can choose from if local code permits.

Deck skirting shouldn’t touch the ground, especially if you have a wood deck, which is vulnerable to moisture. Ideally, you should leave at least 3/4 of an inch of space between the deck skirting and the ground for more ventilation. Pros also recommend that you incorporate about 1 square foot of space for ventilation for the underside of the deck to every 150 square feet of decking. Proper ventilation prevents mold growth and rot that can damage your deck.
