"As the owner/manager of Greenstone Construction, Rich Lee took over the basement development project after the planning and design stage. He did his best to meet the project budget, timeline and outcomes. The result was a beautifully finished basement for which many compliments have been received from family and friends." - RPaolo


"Greenstone Construction was very knowledgeable about sustainable construction solutions.
We decided to build our home using integrated concrete forms (ICF). 
Despite this being a non-standard technique, Greenstone was able to delivery the project on time and within budget.
We especially appreciated Rich's communication; he communicates clearly, provides transparent progress reporting, and is available at very flexible hours.
All deficiencies at completion of the project were dealt with in a satisfactory manner, and Rich was willing to personally step in to fix things."
