We could not have asked for a better company to take on our kitchen renovation. Dana was professional, thorough, met timelines, and was all around a great person to work with. We will be calling Greener Building for all of our future projects.

Dana helped me out tons when I was put in a tough spot. He came in to fix what another much less qualified contractor had done. He’s so easy to work with and is extremely knowledgeable. He was willing to work with the budget we had and got it done when he said he would for the price he said would. I work with contractors all the time and this was the best experience I’ve had with one in a very long time. Highly recommended.

What Greener building did to my bathroom can only be described as magic! It was a complete transformation from a dated monstrosity to a modern masterpiece. The process was painless as well. They facilitated every step of the renovation and kept costs down which of coarse makes me a happy camper. I’d trust them with any reno and will be using them again.

“I have been involved in Insulating Concrete Form (ICF) construction for over twenty years including installation, design, manufacturing and training.  For the last 5 years I have worked on numerous ICF projects with Dana Rolles. The projects included renovations, party walls, foundations and complete ICF homes, including my own. Dana Rolles demonstrated accurate forecasting regarding timelines and budgeting and professional service. Having a technical knowledge of ICF construction is critical to a project’s success and I would recommend Dana Rolles at Greener Building for your next project big or small.

In addition to ICF projects I have retained Dana Rolles services for numerous other construction projects including drywall, finishing millwork and roofing to name a few  and have been very satisfied with the results.”

“Dana Rolles and his team at Greener Building have been exceptional construction partners for several of our restaurant group’s projects.  We have relied on them for a number of years now for both large and small designs.  Without fail, they have proven to be efficient, timely and cost conscientious without compromising the quality of their work.  Their workmanship and knowledge in this industry are among the best and receives my full recommendation.”

Devin Morrison, Director of Operations at Teatro Group

Calgary, Alberta

“Dana Rolles from Greener Building has done a number of projects at our 1969 Calgary house which needed some work.  His range of skills and practical, cost effective recommendations are very impressive.   He was able to provide accurate, professional quotes for us to review before we committed to each set of projects.


He revamped/repaired some external pillars, walkways, repaired fences and decking, insulated our garage with EPS insulation and set up a ski waxing area in the garage.   He also did some landscaping projects around the base of our mature evergreens.  The neighbours sure noticed how attractive that was as he got many of them asking for him to help them out. I would recommend Dana for your home renovations.

I have also had experience with Dana working as the Lead on several Advantage ICF job sites.   He understands the system very well and has become one of the most experienced ICF installers in Alberta.”

"I’ve worked with Dana since his first day of ICF construction, he is a extremely hard worker with a strong work ethic and desire to learn more and further the simplicity ICF construction.

We have worked directly with Dana in testing certain ICF products and Various scaffolding designs for P&W construction. I have relied on Dana for Honest feedback and valued his opinion in making ICF construction a smoother process for everyone.

Through the years i’ve seen Dana go from a project manager with Hamilton homes, now a successful business Owner at Greener Building, im look forward to working with Dana and Greener building on future projects."
