Getting new siding on your home is a significant investment. But here is something many homeowners do not realise until it is too late: the quality of the product you choose matters far less than the quality of the installation behind it. Two homes can receive the exact same brand of vinyl siding. One can last forty years with no issues. The other can begin buckling, cracking, and allowing moisture infiltration within a few years. The difference almost always comes down to whether vinyl siding installation quality standards were followed from start to finish.
