I’m a local Realtor and reached out to Preet at Western Insulation on very short notice after a home inspection raised some concerns about the attic for my buyer clients. We were working with a very tight subject removal deadline and needed someone who could get to the property quickly and give us a professional opinion. Preet was fantastic. He made the time to come out, walked us through what he was seeing, put our minds at ease about the bigger concerns, and had a clear written quote back to us incredibly quickly. He was knowledgeable, professional and genuinely helpful when we were under a time crunch. As a Realtor, having reliable tradespeople I can confidently send to my clients is incredibly important. I would absolutely recommend Preet and Western Insulation and will be keeping his contact information for future clients.

Do you have an infested attic? I had raccoons, birds, rats, squirrels and mice in my attic over the years, and was concerned about hazardous infestation. My Surrey neighbour had their insulation topped up, and recommended Western Insulation Ltd. The owner Preet Sangha and his hard-working staff were respectful and professional at all times. Preet took the time to review options, and patiently answered all my questions. Rather than a top-up, I opted to remove the infested insulation completely. First sheets were laid down to protect flooring, stairs, etc. The hazardous infested insulation was removed, new batting was installed around the skylights and spacers were installed to enable circulation. Then 16” of new insulation was blown-in. The crew even cleaned up and vacuumed before leaving The difference in attic temperature was immediate. It felt warmer. The new insulation would ensure that it’s warmer in the winter, cooler in summer, reduce heat loss by 25% and cut energy bills by 20–30%. I like that it’s durable, eco-friendly, and built to last 25+ years. And, I received a $900 home renovation rebate. Western Insulation Ltd. deserves their A+ rating by the Better Business Bureau. It’s a great company!

I highly recommend Preet and his team to anyone looking for professional attic insulation and ventilation work. The team did a fantastic job blowing in additional insulation throughout my attic and installing baffles to improve airflow and ventilation. The workmanship exceeded my expectations. The team was thorough, paid attention to detail, and left everything clean and tidy when they finished.

Preet and his crew were very professional. They were in and out in no time at all and made sure they cleaned up after themselves. I would highly recommend them.

Frequently Asked Questions

Proper ventilation is critical to roof insulation performance. We carefully calculate the required ventilation based on your attic’s square footage and ensure balanced intake (soffit) and exhaust (ridge or roof) ventilation. This prevents moisture buildup while maintaining the insulation’s thermal performance.
Yes, we offer specialized solutions for cathedral and vaulted ceilings, including high-performance rigid foam insulation, spray foam applications, or creating ventilated channels to combine effective insulation with proper airflow. The specific approach depends on your roof construction and access possibilities.
For homes in our climate zone, we typically recommend R-40 to R-50 for attic spaces and R-30 to R-38 for cathedral ceilings to optimize energy efficiency and meet or exceed building code requirements. The exact recommendation will be based on your specific home conditions.
Yes, comprehensive roof insulation combined with proper ventilation significantly reduces the risk of ice dams by maintaining a consistent roof temperature and preventing the freeze-thaw cycles that lead to ice dam formation. Our approach addresses both insulation and air sealing to maximize effectiveness.
Most residential roof insulation projects can be completed within 1-2 days, depending on the size and complexity of your roof system. More complex projects or those requiring extensive preparation may take longer. Our team provides a detailed timeline during your assessment.
