Frequently Asked Questions

Free Patio Cost Calculator FAQs

What material should I choose for my patio?

Stamped concrete is the most budget-friendly; pavers are the most popular middle-ground; flagstone and travertine are premium natural-stone options with the highest cost per square foot.

What drives patio cost the most?

Base depth and site access are the biggest cost drivers — a proper compacted gravel base is what keeps a patio from heaving and cracking over time.

How big is a typical patio?

A common starting size is around 300 sq ft, which at $35/sq ft starts around $10,500 installed, though every yard is different.

Do I need a permit for a patio?

It depends on your county and whether the patio is attached to the house — use our free Permit & HOA Checker tool for county-specific guidance.
