Mark Peters came to look over the work we wanted - to tear down our old garage, leaving the slab in place, and haul away the contents - and Mike Evers followed up by email with an estimate and contract. It turned out that we were responsible for pulling permits, because Mark-One is a demolition company, not a contractor. So that put the job off for almost a year, while we got around to dealing with utilities and city to get the permit. (It didn't take a year to get the permit - it took a year for us to get around to having the electricity disconnected and scheduling an inspection by National Grid!) Mike was very helpful via email as we worked that part out, and very patient and professional. A year later, when we finally got around to getting the permit, Mark-One still had all our info and the original contract, which had to be changed a little, then the schedule was set, and a crew showed up with a backhoe and a dumpster. We also wanted some pavers that we had been storing in the garage to be moved to behind a shed, which they contracted to do also. I was home when the garage went down - a thrilling sight, which the crew also apparently enjoyed. I left for work shortly after that, and came back home to a perfectly cleaned-up site, dumpster gone, every splinter, nail and shard of glass picked up, garbage gone, slab swept, and all our pavers neatly stacked behind the shed. We paid $700 down by credit card, and the remainder on completion. All in all, a good experience. We've used them since, also.
