The answer to 'how often to patio installation' is that the frequency of patio installation can vary depending on the material, usage, and local climate. Generally, a well-constructed patio can last 15-25 years with proper maintenance. Concrete patios may need to be resurfaced or replaced every 10-15 years, while natural stone or pavers can last 20-30 years with regular cleaning and sealing.
It's important to keep an eye on your patio for signs of wear and tear, such as cracks, uneven surfaces, or discoloration. Addressing any issues promptly can help extend the life of your patio and prevent more costly repairs down the line. If you're unsure about the condition of your patio, it's best to consult a professional landscaper or patio installation expert for an assessment.
