"We had an exterior door to our garage that would not close/latch properly and therefore presented a security risk. I called multiple companies for quotes and explained we'd like to try repairing the door first, but are open to replacing it if necessary. Multiple other companies told us there was no other option but to replace the door. Robert's company was the last one on our list to gather a quote from. He came by the very next day after I called, immediately found core problem with the door (simple loose screws in the hinges) and fixed then and there. The fix was so simple, he didn't even charge us. I so appreciate that Robert wasn't trying to scam us into a bigger more expensive project of replacing the entire door. He is honest and quickly finds the root of the problem. We will be hiring Robert's company exclusively moving forward for our various projects around the house. Feeling so lucky to have found him! Thanks so much, Robert!"

"George Krinninger & Sons deserves your business. They were phenomenal and I would use them again if I ever needed to have a door installed. When we were looking to have our front and back doors replaced, we went to Menards to look at doors. While we were there, a sales associate recommended we reach out to one of their preferred contractors, George Krinninger & Sons, to assist us with replacing the doors. We did and it was the best decision. We worked with Mike and he was incredible. He was very knowledgeable, responsive, and walked us through the whole process. He even went out of his way to go with us to the store to help us pick out the right doors. When it came time for the installation, he showed up right on time, was incredibly professional, and a pleasure to chat with. When the project was done, he left the work area spotless and walked us through any features the doors/locks had. The quality of his work and the experience we had with George Krinning & Sons really speaks for itself. We highly recommend you use them."

"Great! The roofing crew was punctual, professional and neat. If not for the new roof we wouldn't even know they were at our home leaving it clean and everything back in it's place."
