Dennert garage door co. offers excellent service and if a customer has any questions they will be glad to answer them. If a customer hears a noise they are not comfortable with, they will send out their sales rep at no charge to advise customer if a service call is needed or just some routine lubrication. They give a 10% discount on some items for cash or check and a 7% discount on some items for credit card. I believe thats what the previous reviewer made a mistake on. Its Illegal to charge extra 3% for c.card and they dont. The previous reviewer just got less of a discount with a c.card. They are a ""make the customer happy "" kind of company and will follow up any problems that may occur until that goal is reached.
