We are very pleased with the expertise and hard work of DeMarr Construction to install and connect our exterior water line from a private well to the Fairfax Water main.
L.J.Brendan explained the process and provided a detailed drawing of the impacted area and tasks to complete the work. He coordinated with our community association and Fairfax county permitting. The installation crew completed the job on time, filled the trench, and covered the area with grass seed and hay.
We especially appreciate the clear communications throughout the process and highly recommend DeMarr plumbing.
