A concrete patio budget should identify the size, slab design, site preparation, finish and work included in the quote. Current local proposals are more useful than an undated national average. New installation, replacement and a decorative treatment over an existing slab are different projects.
Measure the area and describe the design
For a rectangle, multiply length by width. A patio 12 feet by 16 feet has an area of 192 square feet. Divide an irregular outline into measurable sections or have the contractor confirm the dimensions.
Area alone does not determine the concrete quantity. Thickness changes volume: for arithmetic only, 192 square feet at 4 inches thick is 64 cubic feet, or about 2.37 cubic yards before any allowance. Four inches here is an example, not a structural recommendation. The appropriate design depends on the site, intended loading and local requirements.
Record the desired finish, edges, steps and access. Agree on the actual design before using a unit price to compare contractors.
Separate the work into quote components
Ask about excavation, grading, base preparation, forms, concrete, reinforcement where specified, placement, finishing, joints and curing. Clarify drainage and how the patio relates to the building and surrounding levels.
Also identify access constraints, delivery or short-load charges, protection of nearby areas, cleanup and restoration. Removal of an old slab should be a visible component; see our separate concrete-removal budgeting guide.
Use a clearly defined price example
If an illustrative quote offered installation at $15 per square foot for 192 square feet, that component would be $2,880. If separately quoted removal and disposal were $600, the example total would be $3,480 before any other excluded items. These assumed figures demonstrate arithmetic, not a current market range.
Before adding extras, check what the unit price already includes. A lower advertised price that excludes preparation and finishing cannot be compared directly with a complete installation total.
Compare finishes on the same underlying slab
Plain, colored, stained and stamped work can involve different materials and labor. Ask whether a decorative price includes a new slab or only treatment of an existing one. Confirm appearance expectations and how samples relate to the finished surface.
Consider traction, drainage, cleaning and future maintenance as well as color. More thickness or a more expensive finish alone does not guarantee a problem-free patio. Design, preparation, installation and curing all matter.
Check existing-slab suitability before resurfacing
An overlay or surface treatment is not a universal repair for movement or structural damage. Have the cause of cracks or unevenness assessed before comparing cosmetic work with replacement. Otherwise, the cheaper initial option may not address the problem.
If sealing is part of the proposal, identify the product and whether it is included now or offered later. Our patio-sealing cost guide explains that separate estimate. Manufacturer guidance, such as QUIKRETE’s sealer specifications, applies to the exact product and surface.
Request comparable written proposals
Give each contractor the same measured scope. Record quote dates, exclusions, allowances, payment terms and how changes are approved. Check local approval requirements and the contractor’s relevant credentials before proceeding.
