"I had a bad spot in my deck where some of the boards started to rot and these fine men helped me fix it before someone fell through. They showed up when they said they would and got the job done without any problem. They were nice and I will be hiring them again to help me fix some other problems I have!"

Deck Repair FAQs, answered by experts

The problems with composite decking include a high rate of expansion and contraction from temperature swings. This characteristic can cause boards to split, delaminate, or peel. In addition, significant movement can cause shrinking, warping, twisting, and bending. For this reason, you should minimize moisture and ensure proper airflow below your deck.

Yes, and in some cases, frozen ground may improve the digging process for footings due to sturdier conditions. It’s easier than working in muddy conditions, which are more common in the spring. Contractors may use machinery that makes this step a breeze, so harder ground shouldn’t affect the building process.

Composite decking requires a solid foundation or substructure for support. This base is typically a frame composed of posts, beams, joists, and footings. The frame can be built from various materials, such as composite, plastic, timber, or metal, depending on your budget, deck type, and environmental conditions. For maximum stability, a professional deck builder may recommend installing this frame on top of a solid concrete base. It is best to discuss the most suitable substructure design and materials for your specific project with a professional.

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.

While eco-friendly decking, also called composite decking, is a win for the environment because it consists of recycled materials, it has trade-offs. These sustainable options often come with steeper price tags, lack natural wood's warm look, and can become uncomfortably hot under full sun. Some composite materials can also become slick when wet, posing a potential hazard.
