Contractors for interlocking pavers should have a solid distribution network available to find the right pavers for your job. You don't want to work with a contractor who only has one supplier since your paving job will then hinge on that supplier's stock levels. Instead, you should work with contractors who have a diverse range of potential suppliers to choose from. It's also important to work with contractors who have access to their own brick cutting tools. Having a saw on-hand that can make clean cuts is important since no two patios are the same dimensions. If you only need another six inches and the paver is one foot, then you need to be able to cut that down to size. This is also why eco-friendly pavers can be a great option for most people. Regular pavers require specialized power saws to prevent chipping. Newer eco-friendly pavers can be made out of composite materials that are easier on your feet and much easier to cut. This means that the contractor doesn't need to use such a highly specialized tool. When the contractor's costs are lower, then that means that your costs are going to be lower as well.
