Working with Dueck Builders was beyond any expectation we could have had. Our project was the addition of a 12-foot extension to the entire back wall of a 1950s constructed home that resulted in a complete refitting and modernization of the interior. We couldn’t be happier with the result. Our first contact was with co-owner Josh just before Christmas of 2022 and our process got underway immediately.

The most exciting part of that first phase was Josh’s conversion of our graph paper design drawings into his sophisticated CAD system – in no time flat we had 2- and 3-dimensional official designs plus a huge bonus – the opportunity to tour our design in virtual reality! The virtual tour helped us pinpoint a few design problems to address. What fun, though, to walk through our new house that had only existed in our dreams up to that point. When spring 2023 finally allowed excavation to begin, it was a whirlwind of on-site consultations, product decisions and construction, until a short 6 months later, Dueck Builders’ job was done (in fact, under budget) and we moved in.

We cannot praise the Dueck Builder team enough. The management skill and integrity of owners, Cal and Josh, to have brought together an incomparable team – project manager, Mike, who responded immediately to texts, was on site virtually daily and on top of all construction ‘hiccups’; office administrator, Scout, who among much else cheerfully scoured the city to find unique fixtures (and even lent a hand to hoist beams when needed); and Dueck Builders’ highly skilled independent contractors who listened to us and made the small changes we wanted. Special thanks to wizard carpenter, Peter, electrician, Kevin, and heating/ventilation expert, Keith, plus the others we didn’t get to know personally but whose high quality work is everywhere in our new home.

Dueck Builders was exceptional to work with in every aspect from start to finish with our extensive basement renovation. We are so grateful for everything: consistent clear communication, outstanding work, respectful atmosphere, efficient process, clean worksite, clear budget reporting, and especially Cal’s kindness, expertise, guidance and commitment. We love our new living space! We are so grateful to Cal Dueck and his entire team for all of their dedication to our renovation. If renovating or building in the future, I will be calling Cal Dueck.

Dueck Builders are people you can trust. From start to finish Cal deeply cared about every aspect of our project. This team of skilled professionals were reliable, customer focused and a real pleasure to work with. Through exceptional work and a sincere willingness to listen, we worked through the challenges of transforming our original 1950s kitchen into a beautiful functional space for all to enjoy. Thank you!!!


Dear Cal, Your team is really excellent! I thank you so very much. I am very happy, if I may say so. My home is the nicest in Wildwood Park. I shall always ask you if there is more to be done. Warm regards, also to your family.


Thank you for your sincerity and civility in this whole process. I have found it to be a joy to talk with you this whole process. You are a fair businessman and kind person. I have only good things to say about Dueck Builders. Kind regards.


Our dream home is an unconventional, energy efficient design, the building of which required expertise across a number of areas and a willingness to think outside the box. From our first exploratory meeting with Cal we could sense that he would be a great fit based on his breadth of knowledge and experience. Cal was also very willing to bring in outside expertise for specific issues with which he was not overly familiar, which was crucial for the success of the build. Our initial positive impression was validated over the course of about a year, during which Dueck Builders helped us go from incomplete designs to our finished home. Very few issues arose during the build thanks to meticulous planning by Cal and his team. Any issues that did arise (which always occur with new projects) were dealt with to our complete satisfaction in a timely manner. All of the staff were very approachable with regards to questions or concerns, and were very knowledgeable in their craft. Each member of the Dueck Builders team proved to be a skilled craftsman with a keen work ethic, who takes pride in a job well done. We are very satisfied with Dueck Builders and would highly recommend them. In fact we’ve already recommended them to our parents! Thanks Cal, Josh, Payman, Eric, and Peter for building our dream home.

Pam and Dave

I was very happy with the work (foundation work) and will recommend you and Dan to others who require any work. Thanks again.


Our experience with having Dueck Builders build our new house was extremely positive. From our first consultation with Cal, we knew this was the right builder for our ICF house. The team handled the build professional throughout, and had a customer service standard second to none, even when tested by our last minute changes during rough-in stage!

Both my wife and myself would not think twice when asked if we had a good experience – they took so much of the stress out of the process and we can’t recommend them highly enough! Thank you Cal, Robert, Josh, and Crew.

Sincerely, Jeff Coram

Our experience with Dueck Builders was extremely positive. They constructed a unique addition to our home, which we are 100% satisfied with. We were able to work with Dueck Builders in conjunction with our designer, with many of the project design details and building components selected based on alternatives presented by the people on the Dueck Home team. We like the transparency of working with a cost plus contract, and felt that we were in control of where our money was spent. We recommend Cal Dueck and his team for their high level of integrity, knowledge & workmanship.

My husband and I are very happy with the quality, professionalism and workmanship provided by Dueck Builders. Everyone involved with Dueck Builders was easy to work with, patient in answering questions and arranging for tasks to be done, very knowledgeable and experienced, and quick to work out any issues along the way. We contracted Dueck Builders to completely renovate our kitchen over two years ago, which included adding a two-piece washroom, and we’re still so thrilled with the results!

It is my pleasure to know Dueck Builders and the great care they take in building their homes. I appreciate the opportunity that has been mine to market some of the houses they have built. I have been impressed and appreciate the purpose of their builds, their endeavor to build each house not only energy efficient but also with materials that make it a healthy house. It is impressive to me that past customers are invited and encouraged to come to the open houses to see the new builds. I always thought builders preferred past customers to stay away so they would not talk about the problems with their own experience with the builder. Dueck Builders builds with integrity and conscientiousness to insure clients will be happy and not only satisfied but pleased with their experience.

We hired Dueck Builders for our renovations last year and have been happy that we did. Our project added a new kitchen, mudroom and bathroom to our home. We love our new space and have had many compliments. Cal and his crew helped make the process of having renovations done a bit easier. The project went smoothly, in a timely manner, and stayed close to budget. The work done was quality work and built to last many years. Cal was always there when we had questions. We highly recommend Dueck Builders.

Sue & Dana

We are enjoying our house – it’s a great place to hang out, have friends over, cook – just a nice family space. We’ve had lots of parties and have got lots of comments on the high quality of your work. We always make sure to give Dueck Builders due credit!

Bryan and Cheryl

As our family was maturing and we had regular visits from out of town family, we recognized the need to develop our basement into a more livable space. Our basement renovation involved a complete demolition back to the concrete walls and floor, and rebuild. The laundry room was moved to a new location with new millwork, refurbished the three piece bathroom, new bedroom with enlarged window for natural light and egress, and a recreation room with an enlarged window, built-in entertainment unit, bookcase and gas fireplace.

We hired Dueck Builders to complete the demolition and construction based on their reputation for fine work. The Dueck Builders staff and contracted sub-trades were very respectful and considerate of our home and family schedule. They understood our budget and made great recommendations to help us achieve our vision within the money available. The workmanship is outstanding, and we continue to get compliments from friends and family who visit.

We would not have the same satisfaction and quality without the work of Dueck Builders, and would not hesitate to recommend their work. Thanks to Dueck Builders, our project was a great success!

Regards, Brad and Wendy Janzen

I’ve owned my Dueck Builders house for almost 4 years now and have been very happy with it. It is solidly built and very comfortable. Cal has been great to deal with and is always available if I have any questions about my home, even after all this time. When I had a minor problem with the eavestroughs, he personally came over to fix it, even though the problem was caused by the installation company.


Dueck Builders built our home and we absolutely love it. Cal and his team were great to work with and their commitment to sustainable building really means a lot to us.


I’m very happy with my energy efficient home built by Dueck Builders. From the planning stage to completion Cal and Anna Dueck were friendly, professional and courteous, guiding me through all the steps required. The end result has far exceeded my expectations for energy efficiency, quality and detail.

Thank you Cal and Anna for not only building me a house but a Home to be enjoyed for many years.


We just thought we would take a moment to put into words our thanks and appreciation for all your involvement in the building of our house. From your patience and understanding during the lengthy design and permit stages, to the constant communication and great attention to detail during the construction phase, we couldn’t have asked for a more enjoyable builder to work with. Even the tradespeople you brought in were always a pleasure to deal with. On several occasions, tradespeople we talked to had very good things to say about you. One said, “I like Cal , he builds soild houses. He’s not just in it to make a buck.” Another told us that if he were having a house built, he would definitely use Dueck Builders. We have not hesitated recommending you to any family or friends who are looking to build a house.

Dueck Builders has built us a wonderful tailor-made family home we never intend to leave! The ability to use energy efficient materials and choose exactly the finishes we wanted, such as ICF walls, geothermal heat, cork and reclaimed wood flooring and under floor heating, made us choose Dueck Builders and they did not disappoint. The decision to built a home is one of the biggest we have ever made and we are grateful to Cal and his team for their professional, creative and caring service. The whole experience was very enjoyable and we would not hesitate to recommend Dueck Builders to build the house of your dreams.

November 2010 marks our second complete year in our ICF built home. When we had the energy efficiency test done we scored an amazing 81%, the highest the technician had seen in his 15 years of testing. Our energy savings have been +65% from what we paid in the original house we tore down. Our utility cost for 1 1/2 storey no basement (3500.00 per year) is reduced to under (1000.00 per year) for full 2 storey with basement. I think that is amazing! Well worth the extra cost of materials. That’s more than 2 months in mortgage payments per year. Over 20 years… well, you do the math! This was also accomplished by converting from gas to total Hydro, and LED lighting throughout the house, thus reducing the carbon footprint of our daily living.

The quality is exceptional, and the building process took almost half the time to complete, compared to that of conventional building practices. From house raising old home and ground breaking to moving in took little better than 6 months.

We would like to take this opportunity to thank Cal Dueck, Dueck Builders and all those involved for building our home.
