"JDM is one of the best contractors I've ever worked with. They are my go to for all concrete works and I've used their services extensively. A 70'L x 12' tall 2'thick Keystone retaining wall with 2 bends, footings, a 100' sidewalk curb, 1200 sq feet of crushed stone leveling and ground prep. Thousands of sq feet of landscape grading. They've been been spot on every time. For example, the retaining wall, has both low point drainage and face drains, with stepped geogrid tiebacks. This is how a proper retaining wall is done. They even trimmed the geogrid fabric around the blocks 100% pro grade retaining wall. Get complimented on it by other contractors all the time. Footings were 2'round and 1'round dug 4' deep, well below frostline, positioned right on center for steel posts. Ironworker gave a "dang, these footings are dead nuts". The concrete walk had 2 vectors of fall, 2% linear fall and 1% lateral. There are relief scores every 6' and its edges properly shaped against chipping. Obviously mother nature doesn't play nice and poured concrete does its thing, so I bet I could bust out my micrometer and laser level and find some +-% somewhere, or some place where concrete leaked through forms. Its real life and poured material doesn't always obey. I read some bad reviews here and I must say, am surprised. If you communicate to Danelle and Melvin what you want done EXACTLY they will get it done to your speciifications as close as anyone I've worked with. Danelle shows up on time to do the estimates, bids are quick and fair, and the invoice has always been at or below bid. Melvin is a top tier foreman. Asks what you want before every job. He does exactly what you say, so some of the negative reviews could probably have been more thorough with their instructions. Specify depth, degree of fall, give them the architectural prints. You will get what you want. If you want precise results, give precise instructions, and JDM gives me the results I want every time, bar none. I'll build my retirement home on their concrete."
