Outdoor calculators gather the tools for projects in the yard: patios, walkways, driveways, raised garden beds, deck footings and garden walls. Outdoor work mixes trades, a patio might be poured concrete or pavers, a garden wall might be block or brick, so this page groups the existing calculators by the project they serve rather than by material. Each linked tool gives a quantity and, where prices apply, a Low, Typical and High cost range.

Patio choices
A patio is the most common outdoor project priced on this site, and it has two main routes. A poured slab goes down quickly and usually costs less per square foot. A paver patio takes longer but flexes with the soil, can be repaired by lifting a few units and avoids control joints. Running the same footprint through the slab calculator and the paver, base and sand calculators shows both material orders side by side.
Groundwork comes first
Almost every outdoor project starts below the surface. Concrete slabs and pavers both need a compacted gravel base, deck posts need piers below the frost line, and garden walls need a footing or a level gravel pad. Soil that stays wet or soft calls for more base or drainage, and every dig starts with a call to 811 so buried gas, power and water lines get marked.
Drainage and slope
Water decides how long an outdoor surface lasts. Patios, walkways and slabs next to a house need a gentle fall away from the foundation so rain runs off rather than toward the basement, and that slope gets built into the base before any concrete or pavers go down. Low spots in a yard, downspouts that empty onto a patio and soil that stays soggy after rain all point to drainage work that should come first.
Driveways and walkways also need somewhere for water to go at their edges. A surface that ends against a raised lawn traps water at the joint, while a slight edge drop or a gravel strip lets it drain. Garden walls that hold back soil need drainage behind them too, usually gravel and a perforated pipe, or the trapped water pushes on the wall every wet season.
Weather and timing
Outdoor work runs on the weather. Concrete should not be poured on frozen ground or left to freeze while curing, and very hot, windy days dry a surface too fast. Polymeric joint sand needs a dry window before and after activation, and mortar sets poorly in cold weather without protection. Planning the order of work around a dry forecast saves rework.
Permits and property lines
Driveways that meet the street, walls over a set height, decks attached to a house and structures near a property line often need a permit or a survey. Many homeowner associations add their own rules about materials and colors. Checking with the local building department before ordering avoids paying for materials that cannot be used.

Each material has its own hub with more detail: the concrete calculators, the paver calculators and the masonry calculators. Cost guides such as the sidewalk replacement cost guide the paver sealing cost guide and the retaining wall cost guide cover the hired side of outdoor work, and the methodology page explains how all cost ranges are set.
