Although the doors we had installed are very nice and good quality, the arrogance and unprofessionalism of our salesaman overshadowed the experience for us. He was very defensive when asked specific questions about pricing and became sarcastic when I asked if I could get extra keys.......his response,""Well, you can go up to Home Depot and have some extra keys made"". Not a nice guy......like I said, good quality doors but customer service skills and professionalism are lacking. The doors have a lifetime guarantee but I wonder what it will be like to actually get something fixed if needed. Never again for MasterSeal!
