Cornerstone Construction Service handled our full kitchen remodel after a leak from our upstairs neighbors the project ran from mid june through november with most of the work done by early september there were a few design mistakes some delays with materials and moments where oversight could’ve been better but that’s kind of expected with a big remodel
halfway through we also decided to upgrade our bathroom with a new vanity mirror and countertop and honestly that small upgrade made the bathroom look great they were also very respectful since we were living in the apartment during the whole project which we really appreciated
there were setbacks along the way but the team was upfront about everything and fixed issues when we pointed them out in the end we’re really happy with how everything turned out and wouldn’t hesitate to hire Cornerstone Construction Service
