"Zach did everything I hoped for on his visit. He arrived on time and completed the work exactly as I had hoped and on time. In fact the final solution was even better than I had expected. He is knowledgeable, tidy and pleasant to deal with. I heartily endorse his work and recommend him to others. I also provide this without his prompting too!"
