The cost of new vinyl siding will depend on the size of the project, the quality of the vinyl siding, and the quality of the installation. Low-quality vinyl siding without insulation will cost less than a longer-lasting high-quality siding. In addition, poor installation will shorten the lifespan of your newly installed siding. The good news is that replacing your home’s siding with high-quality vinyl siding by a reputable siding contractor will offer a high return on investment and the potential for great curb appeal.
