    Due to exhaust‑fan connection problems and ventilation issues in my attic, I recently had to address mold remediation and insulation replacement to prevent future ice dams on the roof. David and his team were efficient, and highly professional throughout the entire process. During the estimate, David took the time to clearly explain how the work would be carried out. As the hatch to the attic was inside the walk-in closet in the master bedroom, his team contained the closet and master bedroom. A machine was put inside the room to remove any contaminated air to outside the window. He walked me through the procedure again before the job began. After the work was completed, he reviewed every item on the quote with me, using detailed before‑and‑after photos. On top of that, his team fixed an exhaust‑fan connection issue in the attic—beyond the original scope—at no extra charge. For a project that required three people over two days, the cost was very reasonable. Excellent workmanship and outstanding service. I have no hesitation in recommending David and his team.

    We just had our attic insulation topped up as part of the Greener Homes rebate program. Celluloseman were recommended to us and we are so happy that they were! The crew that came were friendly, explained the process, were thorough, and were very neat by tidying up afterwards. We will definitely recommend Celluloseman to our friends and family who ask. I already feel a difference!

    Out of about 5 quotes, Celluloseman came first, but they were also recommended by someone. David came first to have a look at the attic as it needed to be re-insulated based on the inspection report. He explained what exactly needs to be done and showed the issues with pictures that he took. After I booked the appointment, he came with his team and they did a phenomenal job. Highly recommended!!

    David and his team did attic insulation in our house few months ago. They did a really excellent job! Very professional, quick, and accurate, at a reasonable price! They added A LOT of fiberglass, so the second floor became much warmer. I strongly recommend this company to everyone who needs to do attic insulation. I wish all the contractors were like them!

    David and crew are a top notch company with their exceptional experience from start to finish. We were very impressed with how clean and organized their service is plus their attention to detail in explaining the process of the mould remediation using Abatement Technologies chemicals and air filtration units. David and Daniel took the time to explain which insulation would be best for our home. We are very satisfied and happy clients. We highly recommend The Celluloseman to anyone looking for such services. Thanks Again!
