Quirky corners and challenging floors were what one customer remembered in an August 2022 Google review of Knollstone. They said Greg brought ideas and experience to those awkward spots, understood their priorities, and worked with a team they praised for care and skill. They were pleased with the finished space. Knollstone Contracting is based in Concord. Its BBB profile names Greg Baier as owner and lists construction services, kitchen remodeling and hardwood-floor contracting. Google showed a 5-star average from four ratings in August 2026. In March 2021, New Hampshire Business Review described an early-pandemic drop in business followed by a quick rebound.
“several days after Knollstone Contracting of Bow finished the installation of the new wooden decking on the ski jump.”
“"Do you need this addition now, or can you get away with it in like two years from now?," the owner of Knollstone Contracting has told clients in recent weeks.”

We had some quirky corners and challenging floors, and Greg had the ideas, the experience, and the know-how to manage those spots. We couldn't be more pleased with the result! Greg and the Knollstone Team will work hard to make sure that what you've envisioned becomes your new space.
