We've purchased doors and windows from McDaniels on several occasions throught the years. We have never been disappointed! They will assist in selecting the proper door and help with insuring the fit is correct. We have never really had any problems with the products that they sell. From other's that have had a product fail them, McDaniel's stand behind the products and deal with the manufacturers themselves. You are not left to deal with the warranty yourself! How's that for service?! I highly recommend this company!
