"They did an excellent job from the quote to the finished work. I couldn't be home for either the initial inspection/quote or the actual work. This was not a problem as they handled all my questions and provided both the quote and invoice via Angie's chat on this site. The actual work, after a couple days for the mortar to dry, is totally indistinguishable from the 25 year old adjacent bricks and mortar. The color and style matching of the 4 replacement bricks was perfect. Without knowledge of what it looked like before, there is nothing to tell you that anything was ever done to the brick facade. They even replaced a section of caulking where the replaced bricks met the wood frame. As with everything else the color matching of the caulking was perfect. The cleanup was excellent, they left nothing for me to do."

"Quick and easy."

"Bob, the owner, was a great listener and made sure that he understood my problem before proposing a solution. He has the latest technology and could clearly identify where I was losing heat and knew exactly what needed to be done to resolve my issues. He wanted me to look in the attic so that I could observe that the work was done as he committed. He was very conscious about prepping my home, my carpet and protecting his work areas so that no dirt came into my house while he was bringing his equipment in and out. He was also a very good communicator and did the work in a timely manner."

"Mark was exceptional. We reworked the scope of work several times to fit my budget and evolving needs as we decided to change our entire plan for the basement. The work he did was exceptional. I would definitely hire him again."
