Planning an outdoor project
Outdoor jobs split into builds and ground work. Decks and fences are estimated from their size and material (and a deck wants staining to last). Beds and lawns are about volume and coverage — mulch and topsoil by the cubic yard, grass seed by the area. Rounding it out, drip irrigation, French drains, and excavation help you water, drain, and prep the site.
Which calculator do I need?
- Deck and deck stain — boards and screws for the surface, then the stain to protect it.
- Fence calculator — posts and panels for a fence of any length.
- Mulch & soil and topsoil — cubic yards and bags for beds, lawns, and leveling.
- Grass seed calculator — pounds of seed (or sod) for a new lawn or overseeding.
- Fertilizer calculator — pounds and bags of lawn fertilizer from the bag's N-P-K number, at a safe nitrogen rate.
- Drip irrigation, soaker/sprinkler, French drain, and excavation — water, drain, and prep the site.
- Pool volume calculator — gallons your pool holds, plus the weekly chlorine and shock that volume needs.
Builds, beds, and ground work
Outdoor projects fall into three buckets. Builds (decks, fences) are estimated from size and material — and a wood deck needs staining every 1–3 years to last. Beds and lawns are about volume and coverage: mulch and topsoil by the cubic yard (where bulk delivery beats bags past about a yard), grass seed by a rate per 1,000 sq ft. And ground work — irrigation, drainage, and excavation — keeps the site watered, dry, and level. Heavy materials like soil and gravel are sold by weight, so confirm tons-per-yard with your supplier.
