So far, everything has gone perfectly. From the moment we met Paul, we knew he was the right person for the job. He took painstaking measurements of everything that needed to be done and then discussed our options and presented us with an estimate. The work was done below the estimated price and it was done perfectly.

Environmental Systems Design, LLC, finished a basement for our house in Fort Collins. The end product is wonderful and Jerry refers to it as his “Man Cave”. The design was perfect, the assistance in selecting lights/carpets/cabinets/etc. was great, and Paul Zopff was always courteous, patient and a true professional.
