Adding a manufactured stone veneer to your home can go a long way toward improving its curb appeal and possibly its overall value as well. If you are trying to sell your house, a custom stone veneer can give it an upscale look that will set it apart from your neighbors. In order to keep costs down some homeowners have decided to tackle the project on their own instead of hiring an expert for the installation. The process is not too difficult and even inexperienced people can install it if they pay close attention to detail. However do it yourselfers often make the mistake of forgetting to seal their work.
