I've used K&M installations (Kris and Larry) twice now.
We had purchased a new cooktop, and K&M was recommended to perform the installation. It was a fairly straightforward job, but they did need to make some countertop modifications. They weren't at all bothered to do the extra labor, and it was a nominal $20 to get the tools and cut the counter. They were meticulous and ensured everything was properly centered. They were friendly, professional, and not bothered my large (and very nosey) dog at all.
Fast forward ~3 weeks when we realized that the new cooktop was a game changer and decided to replace our oven too. We again looked to K&M for the installation and they performed the same great service. While they were here, I sprung a request to 'reinstall' my dishwasher for me (it was NOT done right when we bought it elsewhere, it honestly drove me crazy 2-4 times a day) and they had the time and were very happy to be able to fix this huge pain for me.
5 stars, 2 thumbs up. Awesome company.
