We had a great experience with West County Insulation! They got the job done in a couple days, worked quickly (even in the heat), answered all calls and emails promptly. This is the first home we have built so we had a lot of questions. They were able to give us direction and comfort in the services they offered. We have worked with many contractors on building our home, and they have been the best to work with.

This company was amazing. They were quick to respond, came out for an estimate, had a great approach, explained everything that was needed to improve our insulation, and were amazingly professional. They were prompt and communicated well. They did the job efficiently and left without a trace. Wonderfully professional!

Dealing with West County Insulation has been very easy. They are very professional and their response time has been great. When Sean came out, he not only told me the symptoms for what was wrong with my attic, but what was causing them. I now feel comfortable giving the my business because I know the root issues will be addressed. 10/10 recommend.
