Only Available if Part of Larger Exterior Painting Project. If your wooden door is exposed to the sun/elements, it is important to have the door inspected regularly for signs of the varnish beginning to crack. We will clean the door and sand the varnish in those failing areas. We then add stain to the distressed areas and re-varnish the door. This process is inexpensive compared to the cost of stripping the finish and starting over. Ongoing maintenance is ongoing for stained finishes.
