Amazing work by Jason on patio. He gave a very competitive quote and the work was done in 2 days. Fixed irregularities, nails, sanding and two coats of paint. Will def refer him to my friends and family.

Jason and his coworker were very diligent to fix our furnace chimney that was rotted and in jeopardy of falling down. The flat roofing was also replaced and they noticed that siding and flashing was missing had to be added. These probably were reasons for leak in room below. The only reasons why I only gave 4 stars is because even though it looks so much better and stable than before. It hadn’t been tested with rain yet to see if it will leak. As much as the they were precise in their work (measuring, leveling, adding extra flashing, and tar) some parts were not aesthetically pleasing. Unfortunately I am a person of detail, a little smudge of tar drives me nuts. BOTTOM LINE I WOULD REFER THEM TO OTHERS AND WOULD REHIRE THEM!

John did an excellent job on my front porch re- grouting / gutter cleaning project. After the job was done, I noticed some areas not up to the mark in terms of appearance/finishing. He came right back the next day and completed it to our satisfaction.
