The answer to 'difference between patio installation' is that patios and decks are two distinct outdoor living spaces with their own unique features, benefits, costs, and use cases. Patios are typically constructed with concrete, pavers, or natural stone and are built directly on the ground, while decks are elevated wooden or composite structures built above the ground.
Patios are generally less expensive to install than decks, as they don't require the same level of structural support. They are also lower maintenance and can be a good option for homeowners on a tighter budget. Decks, on the other hand, offer more customization options and can provide a higher-end, elevated outdoor living space. They are typically better suited for sloped or uneven terrain, and can be designed to integrate with the home's architecture.
