Last year, I met with several contractors to build a slate walkway for me. Most refused to even quote on the job, as they said they couldn't source the slate for me. Jorge, on the other hand, was willing to make the effort to find the slate and did a phenomenal job building the walkway. He and his team are true craftsman.
The reason I want to give them an 11/10, though, is due to their efforts this year. The first year after a job, without the homeowner reminding them, they visit each job and reset any loose stones under warranty. Also, for a fee, they hand scrub, dry and seal the walkway.
Unfortunately, the slate had a rare reaction to the sealant and a white film occurred. Jorge, without any prompting,came back 4 different times to use special (and I'm sure more expensive) cleaner and sealant to correct the pathway. He refused to charge me any more money for his materials or the significant number of man hours he invested in the project.
You just don't find that pride of workmanship anymore and I would highly recommend them.
