"Good value and good communication. Marco was able to start our re-decking project early due to weather conditions. He was very flexible with respect to keeping costs low, but refused to sacrifice quality. Late on a Friday he ran out of full length boards, and even though Iâ d approved allowing him to piece boards together, he decided to go back and get more wood since he didnâ t think weâ d be satisfied with the end result. He did this even though he knew it would delay the start of his weekend. Weâ re very pleased with the end result! Weâ ve recommended him to a number of people in the homeowners association."

"I found them to be extremely professional! They did amazing work and fit right in with my budget! They kept me in the loop prior to any change or additional recommendationsb I had to be at work while they completed my deck! They emailed me when they were done and they waited until my son took a picture so I could approve the project! I would definitely use them again !"

"Haven Landscape did a great job. After they completed the project you would have never known that a trench and drains were installed in the yard. Everything was restored perfectly. They identified the problem and resolved the issue."

Deck Maintenance questions, answered by experts

A deck doesn’t have to be perfectly level. Many pros even recommend a gentle slope to ensure proper drainage and increase longevity. The ideal gentle slope is about 1/8 to 1/4 inch per foot away from the property, leading water away from the home to prevent pooling and reduce the risk of damage. It also minimizes rot, mold, and other moisture-related problems. 

In many areas, a floating deck that isn’t connected to your home and stays under 200 square feet and below 30 inches in height may not need a permit. These freestanding structures are often considered low-risk, which can simplify the building process. However, building codes vary greatly based on location. Before investing in any home improvement project, check with your local permitting office for deck-building guidelines.

Yes, you can attach a deck to a mobile home, but it’s important that the work be done correctly to avoid the potential for major damage to your home. Many building codes require that any additions to mobile homes—including decks—be either freestanding or have their own support structures. Getting permits may require submitting the home's original floor plan, the proposed floor plan, framing details, and more. 

Materials for a second-story deck must be weather- and rot-resistant, though the specific choices will largely be determined by your budget and style preference. Pressure-treated wood is on the lower end of the price scale, but it can be customized and stained the way you like it. Composite, on the other hand, is pricier for installation and has fewer options for customization, but you’ll save money and time in the long run because it requires little maintenance.

To flatten a cupped deck board, start by ensuring it’s dry. Then, try flipping the board over so the cupped side faces down and reattach it. If that’s not possible, you can use screws to pull it tighter to the joists or plane the edges slightly to reduce the cup. It’s best to replace severely cupped boards.
