They subcontract other contractors to perform various jobs. I hired them to do masonry work at my house. Even though I had a VERY negative experience with these guys I do have to admit that the actual job performed was ok. The problem was with the job that was not completed. I have to admit that since they did an ok job with foundation around my house I paid them upfront for the entire job that also included completing masonry work on my basement stairs. I took their promise that they will come back and finish the job which i would say was 25% of their entire project. Stupid of me - I know! A month worth of unreturned phone calls by either S & T Coombe or their subcontractor ("K.M.C Contractor"). When calls were answered, I had to deal with listening how busy they are, how flexible I have to be and even after I extended myself fully to accommodate their schedule, they would not come back and finish the job (additional money was even offered just to have them finish it, but of course their other "big projects" are more important. Chasing them down completely ruined any good work that they did. Disrespectful, unprofessional folks with no concept of "customer service". Would not recommend at all!
