will attract each other through the thickness of your finger!

Copper Doors: A Beautiful Alternative
A beautiful and distinctive part of what we offer, our copper-clad doors will transform the entrance to your home. With copper on all exposed exterior surfaces, and your choice of pre-finished hard wood on the inside, copper doors give presence and add prestige to any home. We can custom press your choice of pattern into the copper, and we offer a wide variety of door styles and sizes to best suit your needs.
Copper has been used in architecture for thousands of years and has stood the test of time. It can weather harsh elements, and its natural beauty will only improve with age as it acquires a patina and adjusts to the environmental conditions.Copper is the perfect partner for wood, as it is a natural fungicide. It is actually used in many wood preservatives.
Copper doors are rapidly gaining popularity among high-end builders as they add to the perceived value of your home, and are a benefit when it comes to re-sale.
