Deck and patio area FAQs
Useful context before your next step.
Does this include coping?
The tool reports pool perimeter so you can discuss coping quantities, but the cost estimate applies only to the deck area rate you enter.
What if the deck width changes around the pool?
Split the design into rectangles and add those areas as extra patio, or use the result only as an early allowance before a measured plan is prepared.
