    Install or replace ventilation system-
    Nick and Mike cleared up a code violation on my dryer's exhaust pipe. They responded quickly and did the job right, reinstalling the proper venting pipe to get things up to code. They even anchored a loose gas pipe that I didn't realize was a problem. It was very good work overall and I will call them again should any other similar issues arise.

    The experience we had was absolutely terrible! We DO NOT recommend this company. We've spent over $50,000 and still have an incomplete kitchen. We told Dan at Caledon Renovations, from the very beginning, that we needed the renovation completed as quickly as possible to sell and relocate for work. Dan told us that he could complete the work in 4 weeks. On June 3rd, 2024, demolition began on our whole main floor. Once demolition was complete, no one showed up for 2 weeks. We were constantly told there were issues sourcing product, finally, when he showed up with the floor tile, it was not what we had picked but decided to continue anyway to speed up the renovation. It is now August 7th and it still not done. There were several quality issues that were addressed several times and Dan offered to come back to fix these issues for a 3rd time - we declined. The final straw was when we had a subcontractor show up at our house demanding money or he would place a lean on our house. After speaking to this gentleman, we found out that Dan had not paid him and said it was because we owed money - we were paid up to date. When we told Dan we do not want to work with him because of the trouble he has caused, he offered a refund of $1200 for upper kitchen cabinet doors. Even though we were not satisfied with the refund amount, we agreed. We told him to pick up his sign from our home and give us the refund. That was 6 days ago and we've heard nothing from him. We now have to hire another contractor to finish the renovation which is going to cost us more money and time.

    Install or replace ventilation system-
    I had Fluxair come and run ducting from my kitchen stove to the exterior wall, a bigger project than I was comfortable DIYing. They ran about 20 feet of ducting through my old and unknown ceiling without any issues and got everything hooked up and running perfectly on schedule and on budget (project was delayed due to some robins deciding to build a nest right next to the projected exhaust, so had to hold off a few weeks). Will absolutely be keeping them on speed dial for any future HVAC/ducting issues or jobs.
