Cornering the Market with Quality Workmanship

Mark and his son Jordan are consummate professionals. We have recommended Cornerstone to many friends and all have been delighted. Cornerstone has designed and delivered three major renovations and a bathroom to our 1920s house. Every reno had its design and construction challenges but all were dealt with. Mark reconfigured existing spaces in the master bedroom and in our kitchen/den area with creativity and practicality. It is rare that a contractor is also the designer, but Mark can do it all. Designs were shown to us up to the level of detail as to where plants might go! Sloping ceilings and floors were no problem as Cornerstone has worked with houses both old and newer. Cornerst...

Fantastic work, time and time again! From minor household repair to major renovations, we have been very happy with Cornerstone Construction. They don’t cut corners and they have a great eye for detail. They provide excellent consultations and will patiently explore all options with you. They are also very friendly and respectful, causing minimal disruption when working. It’s always a joy to work with them and I don’t think we’d ever go with any other Contractor!

Mark McLean and his team at Cornerstone completed an outstanding renovation of our home. We could not have been more delighted and fortunate to have connected with him. From the very beginning, we were impressed with Mark's professionalism, his mastery and attention to detail, as well as his understanding of the full scope of our ideas. He was particularly organized, keeping to his original timeline. His diligence and courtesy involving us in each step of the renovation was appreciated, as we always knew what was was coming next. Importantly, Mark kept to our original budget. On top of everything, Mark brought to us his cheerful nature and rich sense of humour making our entire experienc...

Outstanding - highest possible recommendation. We have worked with Cornerstone Construction for over 17 years - Mark and his crew have renovated our entire house. The work included a kitchen addition. Our house dates to 1910 and retains many of its original features. The attention to detail, including period detail, has been exceptional in every project. The quality of the workmanship is impeccable from design to execution. Estimated times to completion have been entirely reliable. Working with Mark has been an absolutely wonderful experience.

We have hired Cornerstone Construction for two projects: the first was the renovation of our study, including carpentry which Mark designed (bookshelves, drawers and cupboards), lighting and new windows; the most recent project was the complete renovation of our master bathroom. Expert planning is one of the keys to Cornerstone Construction’s success. Mark gave us plenty of notice about when the projects were to begin. Both projects began and finished on time, within budget, with the highest craftsmanship, and in a very professional and expert manner. We were thrilled with the results. Mark and his team were wonderful to work with. Mark collaborated easily with the designer we hired f...

Mark and his team did an outstanding job on our renovations. We have used them for two renovations and plan to have them back to renovate our future retirement home. They are quiet, courteous and professional. Mark has extensive knowledge of all aspects of home renovations and the quality of his work is top notch. Our family never doubted that we were in good hands, as from the beginning it was apparent that the Cornerstone Construction team provided superior service. Deadlines were always met, and there was no question of meeting the budget because Mark had a meticulous eye for detail, pre-ordering and delivering everything before the project began. Completing our renovations was a stress f...

If you want it super cheap and don't care about shoddy standards and poor materials, this company is not for you. If you are willing to pay a very fair price for excellent design and execution, and total reliability both during and after the work, choose Cornerstone. We have trusted this company with all of our annual repairs and with major renovations since 2004. We are 100% comfortable giving them the run of the house while we are away.

Cornerstone has done two major renos for us and will do our next one. We would never consider hiring anyone else. They are so professional and wonderful to have around that we miss them when they’re done. Each time they worked for us they stayed on the budget and timeline we agreed to and produced excellent work. We have a beautiful and comfortable home thanks to them.

Cornerstone has done two extensive renovations for us, about a year apart. First, they entirely remodelled our kitchen, laundry, and mudroom. This included walls coming down, all new cabinetry, new (and relocated) sink and oven, built-in appliances, the full deal! The next year they created a new master suite, walk-through closet (converting an old smaller bedroom), and two bathrooms, replacing the entire flooring for the second story at the same time. They replaced all of the windows in the house at the same time. Mark's designs are creative and focused on useful beauty. After both jobs we felt as though we had so much more useful storage space, and more useable space in general. And we lov...
