  • Aeroseal Tech Inc.
    Rating: 5 out of 5
    Plumber in Thornhill, Ontario
    • 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.

    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.

    Put up lighting-
    Mike did an outstanding job replacing my ugly dome lights in the basement and some other areas with sleek recessed gimbal lighting and now they light it up so evenly and has elevated the look of our home. He even helped me out a lot by installing a switch, an extra light and removing some light fixtures for which he didn’t charge me. Very honest and with great pricing as well, I’m super happy I made the right choice hiring Gargano Electric 😊

    I had the pleasure of working with Jonathan and Jason to restore my client's unit after it was left in terrible condition by a previous tenant. The tenant had caused significant damage, including broken doors, a damaged sliding door, and extensive harm to the bathroom, along with scuff marks and wall damage throughout the unit. Jonathan and Jason were incredibly efficient and professional in addressing all the issues. They replaced the doors, repaired the sliding door, repainted the entire space, and performed thorough patchwork on the walls. Their communication was excellent throughout the entire processalways clear, upfront, and timely. They kept me informed of the progress and were transparent about the costs, which I really appreciated. The quality of their work was outstanding, and they completed everything on schedule. Im very impressed with their professionalism and craftsmanship, and I highly recommend them to anyone looking for reliable, skilled professionals!
