Sigma Windows and Doors

In April of 2016 I hired the team at Sigma Windows & Doors again to purchase and install on May 2 and 3rd - 5 fire rated doors. Stan and Mike always arrive on time, work efficiently, clean up while working and behave professionally and respectfully to me, a female homeowner. Some of the work was difficult but they did it with great results. They were also very calm and polite when dealing with difficult neighbours. I would highly recommend them. I will be using them again should the need arise.
