Very pleased with the customer service from Todd and Mark. They were very respectful of my time and my home. Offered explanation for everything they checked and didn't mind my questions. Both very pleasant and personable individuals.

We met Derek on inspection day. He was very knowledgeable. Every question we asked was answered with patience. Any questions we got after inspection he was always there to answer. Groundworks was open for suggestions we had and able to explain why it can be done and why not. They were very flexible and easy to work with. Thank you
