    We recently hired Haus Construction Group to renovate the kitchen and bathroom in our condo unit, and we are extremely pleased with the results. The entire process was smooth and efficient, and the quality of work was exceptional. The Kitchen designer (Andre) did an outstanding job with the kitchen renovation. From the initial design phase to the final installation, their attention to detail was evident. The new layout and the quality of the materials used exceeded our expectations. The bathroom renovation was also a great success. The team demonstrated attention to space utilization and the overall aesthetic of the bathroom were impressive. Throughout the project, Mark and his team maintained communication. They were always responsive to our questions and concerns, which made the entire process stress-free. Mark was particularly aware of the condo building regulations, which ensured a seamless renovation process without any issues with the building management. The team's professionalism and respect for our property were noteworthy. They completed the project within the agreed-upon timeline and budget, and any minor issues that arose were promptly addressed. In conclusion, we are highly satisfied with the work done by Haus Construction Group. We would not hesitate to recommend them to others looking for a reliable and skilled contractor for condo renovations.

    Flew back from Christmas holiday and got in at 2 am on Jan 30th with my little kids to discover my furnace had apparently given up just a couple of hours earlier. I called Or at 7:30 am ( I thought it would be a tough week to find people who can help). Or answered immediately and showed up within 2 hours. He diagnosed the issue within 20 minutes and managed a quick but likely temp fix. Got me a quote on the replacement part before noon, picked it up and showed back up around 5:30pm to install it and let us carry on as if it had never happened. Not cheap - but nothing is these days so I find it hard to make a judgement on value - especially when it come to having heat during the cold weather. But I can still spot prompt and polite service when I see it and this was that. Will definitely be calling again for service as needed.

    • Best of the Best 2025
    • Best of Awards 2025

    Aeroseal Tech specializing in Aeroseal Technology and other ways to improve Air Quality, Air Volume and Velocity for residential and commercial buildings. We take on jobs ranging from simple to complicated and perform all work with the utmost attention to detail and customer service. This way we are able to achieve the best results for our customers which we guarantee for 10 years! Aeroseal Duct Sealing is a patented breakthrough technology that tackles leaks from the inside out. Aeroseal software allows the technician to accurately measure the duct leakage in residential homes and commercial buildings. The Aeroseal process puts escaping air under pressure and causes polymer particles to stick first to the edges of a leak, then to each other until the leak is closed. The technology was developed within the Indoor Environment Program at Lawrence Berkeley National Laboratory, whose IAQ scientists tested it. The research was funded by US Environmental protection agency, US dept. of Energy, Electric Power Research Institute and California Institute of Energy and Environment. The University of California was granted initial patents in 1996 and 1999, and Aeroseal holds an exclusive license to the technology.

    Install or replace gas systems and pipes-
    My mother's stove gas line was disconnected somehow, and carbon dioxide alarm chimed away. Enbridge came and did an assessment, and told us that there was a gas leak. This was very concerning, we had have a certified gas technician come and fix the gas line to the gas stove. Hossein contacted me immediately after posting the job on Homestar, he arrived first thing in the morning to correct the situation. There were some challenges to make the connections, because the line was in the ground, and required breaking the tiles. The work took 2 hours in total, he clean up and asked if we had any further questions. He is a profession service person, and I would highly recommended, he provided high quality workmanship and I am a satisfied customer.
