What Our Customers Are Saying
Our house was damaged during a storm when a tree fell on our roof. We called Klausmair for a quote and they came immediately and walked us through the process and set our minds at ease. The work began on time and finished on time. Very happy with the results and would recommend them to anyone.
I had my roof done by Klausmair, from the very beginning with the sales Manager Kevin, everything went smoothly, and Kevin was always there if I had a question, while I waited for my roof. A few weeks later my roof was on. When they were done they left my place all clean. I was very happy with this company and their expertise, I would recommend Klausmair Construction!
