The answer to 'when to paver' is that the best time to install pavers is in the spring or fall when the weather is mild and the ground is not too hot or cold. This allows the pavers to be installed properly and settle into the ground without being affected by extreme temperatures.
Pavers can be installed year-round, but the spring and fall seasons are ideal for several reasons. The ground is easier to work with, the weather is comfortable for the installation crew, and the pavers have time to properly settle before experiencing the harsh conditions of winter or the heat of summer.
