KEVIN & Karen

Cranston, Calgary

“We have just finished our fourth home renovation over the last 10+ years with Martin and Channel Custom Builders. As has been the case with every home renovation we could not be happier! The renovations have included basement upgrading, a complete exterior renovation with all new widows, stone tile and cedar pergola, multiple bathroom redesigns and the latest a stunning kitchen and butlers suite development.

Ever project has been completed on time, at or under budget and most importantly with no issues of any kind! Spencer has been involved in the last two projects and the scheduling calendar he provides is quite simply one of the best project management information detail I have ever seen. Along with the outstanding execution of the project, their design knowledge is so good that we rarely suggest any changes or additions.

Karen and I highly recommend Channel and as we would not consider using anyone else, we are currently doing a renovation in our daughters condo!”

Rosemont, Calgary

“This is the second time that we’ve the pleasure to work with Channel Builders. Martin and his team are fantastic. The projects we have done, including the most recent indoor gas fireplace project, was managed with a professional prebuild plan, budget, and timeline that you would only expect on larger full renovation or new build. All little details and costs were covered with no surprises.

In both projects we changed scope and it was clearly laid out how the decision would impact cost and schedule and we both agreed to the change order. The job site was maintained tidy throughout the project including consideration for securing areas and accommodation for our pet and children.

You hear and see many horror stories on the trades skipping a couple steps but not here, Channel’s partnership with top trades will leave you with a finished project that you are proud to show off. It is all the little details that give us a great deal of confidence in using Channel Custom Builders and highly recommending them to others.”

Ashley & Bryan

Varsity, Calgary

“Channel Custom Builders exceeded our expectations on our carport conversion project. We entrusted them to manage the major project of converting our carport into a new entryway and bedroom. All details of the project were thought of and time-lined prior to the project even commencing. We were impressed with Martin & Spencer's attention to detail, noticing items that needed repair that we wouldn't have even noted. We also appreciated that the site was inspected daily and kept as neat as possible. The trades they brought in were highly skilled and courteous. The management of this project by Channel Custom Builders made it possible to live in our home during the renovation with minimal disruption. We would not hesitate to recommend Channel Custom Builders for any renovation project."

Elizabeth & Nick

“Channel managed our extensive Renovation professionally and enthusiastically. Particularly impressive was their effective management of unanticipated challenges. Their ability to deal with unforeseen conditions set Channel apart from their competition. We will trust Channel with our next Renovation!”

Mike & Mallory

Lakeview, Calgary

"We have just recently finished a guest bathroom renovation with Spencer and Channel Custom Builders and not only did he make our dream bathroom become a reality, but it was also completed within the exact timeline we were provided with and on budget! This is all any home owner could ask for when hiring a contractor."

"This is not our first renovation with Channel Custom Builders either! We knew exactly what type of high-quality, timely and positive experience we would have with Spencer because we had employed his father, Martin, to be our contractor for our entire main floor and other areas of our home renovations. You name it, walls were demolished, beams put in, all new hardwood floors, a complete new kitchen, electrical, tiling and after all was said and done we could not have been more happy! Every time someone walks into our completely renovated home, their expression is always "WOW" and that is due to the professionalism and determination that Channel Custom Builders showed us in helping us achieve our dream home! We are forever grateful!"

Brent & Susan

Riverbend, Calgary

"Channel Custom Builders just completed a full renovation of our ensuite bathroom and a partial, but still significant renovation of our main bathroom. After 25 years, new life, as well as a beautiful new look now exists in both. We could not be more pleased with the end result of the professional work carried out in both rooms. The project was extremely well managed by Channel Custom Builders (owned and managed by Martin Kathrens) from start to finish and the construction schedule was adhered to without any delays. The degree of detailed inspection during the entire duration of each and every stage of construction was extremely thorough, thus ensuring a high quality of workmanship by all trades involved"

"As the home owners, my wife and I were always kept informed of what was happening with respect to construction plans and the few minor resolvable issues that arose. All parties involved were always receptive to any questions or concerns that came about and the lines of communication were always open"

"Along with extending our sincere thanks and appreciation to Martin Kathrens, we would also like to congratulate and extend the same thanks and appreciation to Spencer Kathrens for his excellent project management handling of our renovation. To both we say "A job extremely well done". It is without hesitation that we look forward to having Channel Custom Builders handle any other major home renovation projects we may incur in the future and would highly recommend them to others looking to renovate"

Nancy & Andy

Scenic Acres, Calgary

"We had our master bathroom completely remodeled by Channel. They were recommended to us by satisfied friends and we were completely satisfied as well. We found Channel very thorough and importantly, respectful of our space. The trades were on time, reliable and we felt comfortable with them in our house. Channel always did what they said they were going to do. They arrived daily and managed all their trades well. Clean up was never an issue. We were kept informed and given a timetable of what was happening when. Any questions were answered in a timely and thorough manner. We are thrilled with the results."

Ken & Jane


“Knowing we were planning some renovation work, a friend suggested we call Martin at Channel Custom Builders. Martin's creative, thoughtful and cost-conscious approach helped to take all the pain out of the renovation process. Channel's trades were pleasant and efficient, and our project was completed on-time and on-budget. We absolutely love our new bathroom and laundry area, and are already looking forward to working with Channel again on a long-desired wine room!”

Raj & Vidya

Connaught, Calgary

“We did our very first renovation a few years ago and I was constantly told as I was going through the process of choosing a general contractor that there will always be significant delays in the timelines proposed and the budget would always over exceed. I was pleasantly surprised when Martin and Co not only completed the renovation in a timely fashion, as well as within budget. Throughout the process, Martin was very helpful with his experienced advice on not only the technical aspects of the renovation, but also the aesthetic aspects. Even today, as I hear my friends talk about their renovation nightmares, I am amazed at how stress less mine was.”

Natalie & Mark

“We are extremely satisfied with the extensive Renovation done on our home. The work was completed on-time and on-budget, as laid out by Channel Custom Builders. Our every expectation was met or exceeded, and we really love and enjoy our fabulous Renovation!”

"We were so pleased with the results of Channel’s complete interior remodel of our home that we are working with them again on an exterior/addition project!

Susan & Scott

Edgemont, Calgary

“With Martin’s help, the interior of our 25 year old Home was almost completely demolished and rebuilt. Everything was done to a very high standard, small changes were accommodated throughout the process and work was completed within our timeframe (5 months). We are thrilled with our “new” Home, and I would enthusiastically recommend Channel to anyone considering Renovations!”

Mary Jo & Paul

“We are very pleased with the results of our Kitchen Renovation. Trades and services arrived when scheduled. The few problems we encountered were dealt with promptly and to our satisfaction. Changes by us were accommodated on-the-fly, with minimal impact on the timeline. The award-winning result is functional and elegant!”

Carolyn & Herb

"I have known Channel Custom Builders, and more importantly Martin Kathrens, for over 10 years. During that time Martin has presented himself as a master contractor. He has the experience and knowledge to ensure the overall success of any project. His relationship with his clients though is what sets him apart. He is easy going and really cares about the needs and wants of his clients. I have recommended Channel any time I am asked for a contractor reference."
