We have used Dima to install a whole house filter a few years ago and they did a high quality job, the filter still works and we have no issues. When we have discovered a leak in our finished basement kitchen, we naturally called Dima to fix it. John (the principal) came in with his helper (his son) very quickly. It took him one minute to determine what needs to be done, he quoted me the price which was fair and half an hour later - everything was done, and the work came with 90 days warranty. Very pleasant people - small family business, who do honest and high quality work. Happy to see so many good reviews - businesses like that should be rewarded.
