We strongly encourage you to allow us to make purchases for you for a number of reasons. Unlike buying on the internet, we have good buying power and good relationships with our vendors who provide excellent support for superior products and materials when needed. Also, we aren’t able to offer a warranty for our labor or the product when we are unfamiliar with the manufacturer or workmanship. Note: Tradesmen and Subcontractors will not provide a warranty for products you buy, for the same reasons.
