4 months old and finish is peeling off…

Would Not Recommend

This door was extremely beautiful but the finish is peeling off and once it gets started it just continues to peel. Unfortunately the quality does not reflect the price. Hopefully Lowe’s will replace this door. We will be calling.

Damaged door

Would Not Recommend

The door was pretty, but it was damaged and scratched. It was returned on Thursday, and no credit to my account as of the following Sunday. The debit is immediate. The credit back, not so much. Not happy.

Nice door but factory needs better quality control

Would Recommend

Door looks nice, seems sturdy/durable. The seals are pretty tight and, once leveled and secured, there is no detectable draft. Definitely good value for the money. Unfortunately, the door arrived with the threshold installed improperly. It had to be removed and reattached before the door could be installed. This is clearly a quality-control issue from the factory. Unfortunately, due to packaging, this issue went unnoticed until demolition was completed and there was no option to return for repla...
