I had a dry-fit retaining wall that was sagging alarmingly, so I contacted DiMarco. Jim asked for…read morephotos, he couldn't make an accurate appraisal so he stopped by within a day or two. He gave me a plan on what he would do, and I could tell he knew his stuff by virtue of remedying causal factors for the leaning, including improper drainage. I also had him look at a 1957 original kitchen exhaust blower that was now a dead end and fall hazard, wanting it taken down -- which I couldn't do safely on my own -- and a frustrating area where water would come into my office when it rained hard with a lot of wind. Jim said all the right things, and I was very happy with his quote. He communicated well via email about when he could come. He and his crew showed up and did a fantastic job. They bricked in the gap where the exhaust came out, properly insulating and sealing as they did so, and painstakingly addressed the likely factors in the water intrusion. I would hire him again in a heartbeat. I wish I had had him work on my chimney a couple of years ago instead of a certain other company who overcharged me and reneged on a necessary service they had promised but carefully not included in the contract. He would have done a better job and charged me less.
