How to Use the Patio Cost Estimator

All outdoor patios must slope away from the house at a minimum of 1/8 inch per foot (1% grade) to prevent water pooling against the foundation. For areas near windows, doors, or basement walls, 1/4 inch per foot (2%) is recommended.
Patio Material Cost Guide (2026)
Plain poured concrete is the most affordable solid surface at $6–$12 per square foot installed. It is low maintenance and durable, but plain concrete looks utilitarian without any decorative treatment. Stamped concrete ($12–$22/sq ft) replicates the appearance of stone, brick, or tile at a fraction of the cost — beautiful when freshly installed, but it requires sealing every 2–3 years to maintain colour and prevent cracking. Concrete pavers ($10–$20/sq ft) offer the same aesthetics as stamped concrete with a key advantage: individual damaged pavers can be replaced without disturbing the rest of the surface. Natural flagstone ($20–$45/sq ft) is the most attractive and highest-value option — each piece is unique, and it adds significant perceived value to outdoor spaces.
Base Preparation Matters
The base determines how long any patio surface lasts. For pavers and flagstone, the standard base is 4–6 inches of compacted crushed stone followed by 1 inch of bedding sand. Skipping or shortening the base causes settling, heaving, and cracking within 3–5 years. For concrete slabs, the base is typically 4 inches of compacted gravel plus rebar or wire mesh reinforcement. Heavy-clay soils need more base depth — often 8 inches — because clay expands dramatically when wet and contracts when dry, causing movement that cracks rigid surfaces.
FAQs
What is the most durable patio material?
Natural stone (granite, bluestone, slate, quartzite) is the most durable patio surface — it does not fade, crack easily, or require sealing (in most cases) and can last 100+ years with minimal maintenance. Concrete pavers come second in durability; individual units can be replaced if they crack, and the overall surface outlasts poured concrete slabs. Poured concrete is durable but susceptible to cracking from frost heave and tree roots. Stamped concrete is the least durable of the common hard surfaces because the surface sealer deteriorates and must be reapplied regularly.
Can I install a patio myself?
Pea gravel and simple concrete paver patios are accessible DIY projects for someone comfortable with physical work. The main challenges are: accurately levelling and sloping the base, keeping paver lines straight, and proper edge restraint installation. Stamped concrete, natural stone, and complex patterns are not DIY-friendly — they require specialized tools and skills. Pouring a concrete slab is a large physical undertaking for DIY that also requires proper formwork and finishing skills. Most homeowners hire for concrete slabs and natural stone; many DIY concrete paver patios successfully.
