Paul Praturlon in Mississauga

We have been dealing with Hanna and Oris for a long time. They are subcontracted thru us to do all type of work. The most recent was to replace an old automatic transfer switch in a high rise condo. Our customer was impressed with their professionalism and promptness. Once the job was completed the work site was cleaned and our customer was very happy. I would highly recommend them for any job big or small.
