A custom stone veneer is a great way to add a little style to your home. It can make your house look like it was built entirely from stone but at a fraction of the cost of natural stone. To save a little money, homeowners with a do it yourself frame of mind have attempted to install their own custom stone veneer. As long as you’re careful, it is possible but you have to be sure and take extra precautions around your windows. If they are not sealed properly then you can leave yourself open to leaks and future water damage.
