What the Neighbors Say

I highly recommend Cory and his team. They cleaned and repaired my crawlspace in bitterly cold conditions and did the job quickly and efficiently. C&C’s estimates came in below those of competitive bids and Cory was fastidious about checking and double-checking the quality of work and communicating quickly and effectively with me. Before C&C’s work my crawlspace was odiferous with dead rodents, insulation that was no longer satisfactory and duct work that had long been forgotten and was not working optimally. No more funky smells coming from that dark space now.

Lauren Kramer

We used the Insulation Company to put in new insulation in our attics and crawl space. They also did some additional crawl space repairs. Cory and his team are amazing!!! Throughout the entire process communication was excellent and the work done was perfect. Everyone went above and beyond. I highly recommend the Insulation Company!

Erica Baldridge

Fast, reasonably priced, and high quality work. Cory was very informative throughout the process and I appreciated their flexibility with scheduling. Highly recommended!

Genevieve Boushey

Couldn’t be happier! This is the best business of any kind I’ve worked with in Bellingham OR Seattle. They were friendly, polite, prompt, conscientious, and professional. Thanks for the excellent service!

Katie A., Blaine, WA

All of the services provided and work completed were of top quality. The Insulation Company was very responsive to our need for the work to be done on a tight timeline in anticipation of a property sale. We are extremely satisfied with the work and would certainly hire them again in the future and recommend them to others.

Victor N., Bellingham, WA

Christian and his team moved quickly to get to our house and give us an estimate, which was a very reasonable price for the work that we needed. The Insulation Company did a great job communicating with us throughout the process and were quick to answer any questions that we had about the work, cost, product used, etc. They also use a very clear, professional software to notify us of upcoming service reminders and balances which has been really helpful for tracking purposes.

We totally recommend The Insulation Company to anyone else in the area that’s looking for a top-notch service provider.
