The cost to build a deck around a pool typically ranges from $3,000 to $12,000, depending on the size, material, and whether you tackle the build yourself. Most people pay an average of $5,000 for their pool deck project. Hiring a pro to build a pool will cost you more for labor, but it will be worth it to ensure a safe and secure installation.

What goes under your floating deck depends on your preferences. Some homeowners put landscaping fabric underneath their decks to prevent weeds from popping up through the boards. Others choose to build a floating deck over grass or gravel. However, it’s best not to set your deck directly on the ground. Instead, set your deck on blocks to keep it elevated enough to prevent moisture from rotting the wood.

Finding a reputable deck builder should start with speaking with a local company and asking for samples of past work and references. You can review the company’s workmanship and speak with past customers to learn what the customer service was like throughout the process. It’s also a good idea to read online reviews and check the Better Business Bureau (BBB) website to see if the company has a history of customer complaints. If you can get a referral from a family member or friend, that’s another great option.

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.
