That 2016 customer also said Craig Cooper built a commercial recording studio for them. In a 2016 review, a customer said Craig and his company had built 2 custom homes for them over the past 12 years, ranging from 3800 square feet to upwards of 7800 square feet. A 2016 customer wrote that Craig and his team built their new house in 2015 and that it was done on time and under budget. In a 2016 review, a customer described a fully executed build that began with help choosing a lot and reviewing home designs.

In 2016, a customer wrote that Craig rebuilt their house room by room and that the work was done on time. In 2016, a reviewer writing as architects said they had worked with Rainbow Construction for more than 25 years.
As architects we have worked with Rainbow Construction for 25+ years. They do top notch work and we would recommend them to professionals and homeowners alike.
The greatest compliment a business can receive is when a client returns, ready to hire that business for their next project. Over twenty years I have utilized Rainbow Construction for five major projects and will rehire this company for my next project when it arises. Enough said.
Simply the Best! We have lived in our home for 36 years and have completed several renovations. Never have we dealt with such a talented group of craftsmen led by the most organized and honest professional we have ever worked with. Had we not hired Rainbow for our latest project the outcome would have been much different. They worked around any obstacle that came their way and the finish work is incredible. We will never work with any other company from here forward.
Rainbow Construction is by far the best building contractor Cumberland county by ! I have used Craig and his company to build 2 custom built homes for me over the past 12 years ranging in size from 3800 square feet to upwards of 7800 square feet. His competitive pricing and excellent subs make the building process exciting and fun. Craig's knowledge and understanding complements his skillful craftsmanship and desire to please the client. I would not hesitate one second to use Rainbow construction for your next building project. Foundation to finish trim and flooring you will be pleased with the quality and work ethic on your project.
