Originally, as you can see by our review below) we were very happy with the installation of our…read moreJames Hardie board. Unfortunately we found out the hard way that Grennan Construction does not stand behind their work. During the installation they made a human error and did not caulk and apply flashing correctly which led to a leak to our dining and living room ceilings causing over $2,000 worth of damage. We have made close to 20 texts or phone calls to Fred, his employees or his office in an attempt to have them come out access, and effectively stop the leak. They told us it was fixed once, we had the inside of our home professionally repaired and painted only to have the leak return shortly afterwards. Go Elsewhere!! Was referred to Grennan Construction by a trusted source and they didn't disappoint. The crew was very polite and conscientious from beginning to end. The Hardie board installation looked good from day one and continues to look great. You should definitely use Grennan Construction if you the job well done at a fair price and on schedule.

So, we needed the gutters cleaned at our office here in Troy and it was my job to find someone to…read moredo this task. Between the pandemic and staff changes, we had no clue the last time the gutters had been cleaned. Some of them were even coming off the roof! Plus, with all the rain we've had, the gutters were literally taking a beating this summer and needed attention. After getting several estimates, C&G gave us an awesome quote and came out in person to check out our building. While it's not a tremendously huge building in comparison to some others in the area, it was still going to be a lot of work due to the amount of debris that we had going on there. Two really nice guys showed up and not only did the entire building in two hours, but tacked back up the gutters that were falling off the side of the building as well. They also cleaned up their mess and hauled it away from all the stuff that got blown out. They also showed us other repairs that may need to get done in the future to keep the roof and building in good shape. Overall, these guys do really good work at a very fair price. We will use them again and they were super efficient and professional. Thank you C&G, you guys rock! Our building looks beautiful again!
