"Tim was prompt, professional & listened to my questions and answered my questions patiently. His knowledge of materials and costs helped me get this project done well & in my spending plan too. My decks are now in great shape, look better than they have for some time, since Dominion’s very skilled crew replaced worn decking and stained the deck and railings. Our family can really enjoy this special part of our home for years to come now!"

"Very satisfied with Pro Line construction from start to finish.Tony came to measure and do a full and detailed presentation on what the new roof would entail. They are platinum installers for Owens Corning - which means they receive extra training for the latest materials in the business. Unfortunately , because of the fickleness of weather they couldn?t come as quickly as hoped. However , once they came they were amazing. I had 7 men ripping off my two layer roof and garage roof - and they looked like Santa?s helpers. The dumpster filled and materials were stacked all over the lawn and they never stopped working. The project manager stopped by several times a day and got on the roof to monitor progress. By the end of the second day the job was done. They didn?t leave until 7 pm and after blowing clean my deck and lawn. It was spotless. Awesome job well done"

"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."

Deck Repair FAQs, answered by experts

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.

Choices include wood, composite, and hardwoods, each with unique benefits.

Deck repairs cost around $800 to $3,500 . However, your cost depends on the type and severity of the repair, as well as the type of decking material you have. Other factors, like location and labor costs, impact the price, too. Boards and railings are the priciest parts of a deck to repair, while loose stairs are less expensive to fix.

Composite decking requires a solid foundation, substructure, or subframe to ensure stability. This base is typically composed of posts, beams, joists, and footings. The frame's joists can be built from various materials like composite, plastic, timber, or metal, as long as the base can support the deck's weight without shifting. A professional deck builder might recommend installing the frame on a solid concrete base for added durability. The final design and materials for the substructure will depend on your budget, the type of deck, and environmental conditions.

A quality, well-maintained PVC decking can last 30 to 50 years. It’s known for being one of the most durable types of decking materials, with composite decking having a 25- to 30-year average lifespan and some softwood deckings only lasting 10 to 15 years. Luxury hardwood decks like Ipe may last longer than PVC decking, but they can cost more and require more maintenance.
