I was very impressed from the first contact. I was concerned about a leaking window and potentially mould in my baby's room. Although he was booked for weeks, Jon made arrangements to come and do and estimate and I was impressed with it. It was concise and detailed. Then when I said I wanted to proceed he made arrangements to come over and get it done quickly, rearranging a couple of jobs because of my mould concern. He and his team member showed up on time, were very pleasant and did a super job. No mould thank goodness. Windows are now safe and leak free and he undid sloppy work of my exterior painter. I contacted two references and both raved about him. I now have my best friend hoping to have him do work for her. I was extremely satisfied and am having him do some more work in the next 6 months.
