Very happy with the new roof put on by Grieff's. The work was done in a timely manner and while putting on the new roof they found 2 issues that we were not aware of and fixed them for us. Testimonial written by Steven McGregor on this site.

Grieff's work is outstanding. Our windows look beautiful. Staff is so courteous and honest. The work was done in a very good time frame and they made sure I was satisfied.

On 3/12/2024 Jeremy Missel had this to say:
I recently had an exterior house fire and I hired Grieff's to replace the burnt siding and to replace a sliding patio door with french doors. They did a phenomenal job and were finished in one day. The owner made a couple trips to my house to be sure the measurements for the new door were spot on. Keep in mind that a contractor that does great work is usually super busy for this reason, everyone wants their quality of work. Be patient with your project as far as the wait time. Excellent quality is hard to come by and that is why Grieff's is really busy all year round. Grieff's is worth the wait and their prices were very reasonable. I would highly recommend Grieff's to everyone I know. I wouldn't call anyone else for my exterior home projects from this point on. Great company and I highly recommend Grieff's Exteriors!

We are so pleased with the installation of our windows, the guys were great!!! They were very professional and cleaned everything up before they left. We have already decided to have them installed our new gutters. I will continue to use Grieff's for all the services they provide. Testimonial written by Joe and Mary Dunham on this site.
