Grennan Construction

Grennan construction responded to my request for service immediately. They assigned a manager for my job. He came to our home several times to ensure the project goals, expectations and our needs were being met. Work was done quickly and clean up was fantastic. Highly recommend

Very happy with Grennan construction some people we knew had them work on their house , new siding etc, i asked if they liked the work they did and they were very happy , I contacted them to do some updates to my home , primarily siding (Hardiplank) , very happy with the craftsmanship, they worked very hard and completed the job quicker than anticipated, I am having them do some siding around an additional window and I’m confident they will do an equally excellent job

Since I added extra insulation to my attic, I noticed a significant decrease in my utilities. Great to do business with .

We live in the UP of Michigan and was having issues with finder Neg a company that knew how to figure out hardie siding, and all aspects of it. I found this company online and within a few hrs I had a phone call and text and was able to figure out everything we needed and how to do it with the help from these guys. They went above and beyond to help us and told us to call or text them with any questions we have during our process. I would recommend them hands down. Great company!!!
