I knew I had an insulation problem, but I honestly didn't know who to call. I went on Google and found Sean's company had 5-star reviews, so I made the choice and I'm glad I did. If you guys need someone who is honest and cares about your issues, don't hesitate to hire Sean. He also made sure to message me back and check in to make sure everything was okay.

I had an amazing experience with Bowmanville based The Same Guys Insulation and highly recommend them to anyone in the Durham Region looking for reliable and honest attic insulation services. Sean and his crew were kind, helpful and incredibly considerate throughout the process. Sean provided multiple tiers of options and offered genuinely helpful advice during a difficult situation involving a deceased family member’s home. His transparency and care really stood out. The crew removed the old materials, re-insulated the attic side walls, topped up the attic insulation and handled soffit ventilation and weatherstripping. They worked efficiently, communicated clearly and treated the home with real respect despite it being an unusual attic. If you are in Bowmanville or the Durham Region and need attic insulation, wall insulation or ventilation improvements, The Same Guys Insulation is the team to call. Exceptional service, fair pricing and genuinely good people. Highly recommend.Posted on Benjamin LundriganTrustindex verifies that the original source of the review is Google.
