Practical guides on deck cost, materials, permits, and timing — written for homeowners and pros.
Every article here is written to sit next to a calculator: the post explains the decision, the tool puts your own numbers on it. If you are pricing a new deck, start with the deck cost calculator and the deck cost by state tables, then read about timing and permits below. If you are choosing a surface, compare the wood and composite cost calculators, which include upkeep over 25 years. Planning to build it yourself? The DIY deck cost calculator shows what the saving really is once tools and the permit are counted.

Where to start
Pricing a deck
Start with how much a deck costs for the national ranges and the line items that push a quote up: footings, stairs, railings, demolition and the permit. If your deck is the common 12 × 16 ft size, the 12x16 deck cost article works one example through by material. Where you live matters too, so check deck cost per square foot by region before you compare a quote with a figure you read online.
Choosing the decking
Composite vs wood compares the upfront price with sealing, staining and board replacement over the life of the deck. Trex vs TimberTech goes one level down, to capped composite against PVC, once you have already decided against wood.
Planning the build
Read the deck permit guide before you draw anything, because height, attachment to the house and footing depth decide whether you need one and what the inspector checks. DIY vs hiring a contractor weighs the labor saving against tools, time and mistakes, and the best time to build a deck covers how the season affects contractor availability, lead times and working conditions.
