DanMar Construction LLC

A recent DanMar Construction customer hired it to replace a sewer drain line beneath a concrete basement floor, and said Mark and his crew cut through the concrete, removed the old pipe, put in a new one, backfilled and poured fresh concrete over the repair, then cleaned the work area. That customer added that Mark answered all their questions throughout the job. The company describes itself as a North Haven remodeling contractor serving all of Connecticut and says it has more than 15 years of experience. In 2025, a customer said Mark and his crew put an addition in their basement, kept the site neat and clean, and were easy to reach by text or phone. That 2025 customer also said the price was reasonable. It holds 4 stars from 4 Google ratings, and its BBB grade is A+. Connecticut lists its home improvement contractor registration, HIC.0629206, as active, held by DanMar Construction LLC.
