We had a great experience with Keystone! We first hired Eric, owner and structural engineer, to give recommendations for taking out a few load bearing walls and beam specifications during a remodel project. We later hired his team fix some foundation issues we were having in our basement (wall bracing, french drain, waterproofing, epoxy, etc) as well as to install two egress windows. Eric, Ronnie, and his team were great, very responsive, and easy to schedule with. We have been very happy with all the work they’ve done!
