Whether carpet or hardwood, All Star Flooring provides an option for an underlayment pad. An underlayment sits between the structure of the subfloor and the material you will be using. This provides absorption for roughness or imperfections of the subflooring. It also provides the material extra support. It can be used for commercial or residential work. Any underlayment and subfloor can be tricky to install and could cause failure of the flooring material if not done properly. There are different types of pads used based on the material you'll want installed, so speak with an All Star specialist so they can better assist your needs.
