The process of getting a new front door was absolutely painless. Sales person came over, i picked the door, paid half. When the door came in, Fran called and scheduled. Installed yeaterday and paid 2nd half. Presto! New front doors. Love them.

Called them and emailed them over 6 times to confirm an appointment for estimates on the house. First, they suggested a date that I agreed with to only get an excuse as to why it wasn't booked. Second, they reconfirmed a date and missed it. Third, called again (on the day of appointment) to ask about the estimate and they said they'd check in on it; I did not receive a call back. Called.emailed. I don't know what's going on. Inquired about replacing the entire 2600 sq/ft house with sunroom and they're MIA. If you're busy, I'd get it.

Being trying to get a warranty repair for a few months. They have yet to return a call as promised. I can't even see giving them one star at the time.

I contracted with Mueller Co to enclose my 12 /20 screened porch on January of 2018 for the cost of 47,000.00. The work finally began in early May and as of February 8, 2019 the porch enclosure is only 2/3 of the way complete! Every excuse for delays have been told to me. They are missing in action for weeks at a time with no communication! This company is poorly managed, disorganized, and how they are still in business just amazes me. Stay as far away from this company as possible!

Muhler really stepped up to the plate when I needed a replacement door for a Sunroom that they had installed over 15 years ago. Because the Sunroom was a Temo product and they no longer did business with Temo, I called Temo directly only to be told that it would cost me over $1000 to have a door shipped to me and then I would have to hire someone. to install it. Well, I contacted Muhler and Jennifer was amazing!

She called Temo, had a discussion with their management and suddenly my door was ordered under warranty to be shipped to Muhler, after which Muhler would do the install. It took several calls to Temo and 2 months to get the process completed, but Jennifer was persistent and I now have a new door that closes properly. The installers, George and Chris were right on time, totally professional, considerate and efficient.

Not only did they uninstall the old door, install the new door (making adjustments to make sure that it was a solid fit), they also rehung the window treatment and re-affixed the security alarm. *****Stars to the Muhler team, Jennifer, George and Chris!
