Our goal is to earn respect through integrity and a superior product. Beauty of wood windows fade as they start to warp, discolor, finishes blister and peel and shrinkage means leaky windows, Swelling means windows that cannot be opened or closed. That's when your windows start to cost you a lot of money and time. Eventually you will replace wood windows because they are beyond repair. Aluminum corrodes and transfers heat and cold. Poor and recycled PVC's can warp and discolor.
