Jo and his team at Insulation Co. did a great job! From the start, I could tell I was in good hands: - I called and left a message with my address and issue (mold in the attic due to a detached stove vent). - Less than an hour later Jo called back. He'd looked up my property on the publicly available city records, so was able to put together an accurate estimate based on my home's sqr ft. - Then Jo walked me through the steps, the equipment, and the timeline. He followed up soon after via email with all the info we'd discussed, plus links to YouTube videos with additional information about the process. He included a line-itemed estimate/contract with clear terms. - On the agreed date, his team showed up on time. They were courteous and efficient, and finished the project later that afternoon. The project lead had taken photos throughout the process and walked me through the work they had completed. They did a great job cleaning up too. Cannot recommend enough!

Insulation Co was quick and thorough. We needed a job done quicker than most. They remiediated our entire crawlspace and replaced our ducts. They made sure to get us on their schedule immediately. Jo even went out of his way to be available to me while he was out of town. They finished everything in less than a day for each job with excellent precision and kind workers. They were also reasonably priced! I would highly recommend them to everyone.

They were very knowledgeable about their service. I had a crawl space cleaned out and insulated. They were very easy to work with, very promt and efficient, and got the job finished. I felt that they were easy to trust and the cost was reasonable for the work done. All of my questions were answered in detail without hesitation. I would highly recommend this company.

After looking for a escapee cat, I discovered the insulation in the crawl space was, like, awful. I phoned Joe, who answered instead of the dread voicemail and we were able to work out an estimate over the phone with the magic of tech. When the day came, the two installers were as good as anyone could be, no mess, no fuss, competent, friendly as well as leaving the outside of the house looking like nobody had been there. They shared pictures of the work which looked over the top, saving me the trouble of crawling under and having a look. I'm really glad it worked out and will highly recommend anyone looking for attic or crawl space insulation to Joe at Insulation Co.

Highly recommend Insulation Co, probably the most efficient process I've experienced as it relates to any sort of sub-contracting for home renovation/repair work. Almost immediately after our initial inquiry, we received both an email and phone call from Jo to let us know we'd be receiving a quote and to also confirm availability. Rather than having to wait for someone to come out and view our attic in person, he was able to provide a reasonable price based on public information records for our property and schedule an appointment in the very near future. On the day of the procedure, his crew showed up on time, got to work quickly, and was finished within the time frame they'd estimated. Upon invoicing, we had multiple payment options and were able to quickly put a close to the project. We'll absolutely be reaching back out to them for future work, thanks Jo and team!

They cleaned a rat infested crawl space. Impeccable work and a very nice door manufactured for the crawl space. Also did some foam insulation as a courtesy. Very easy to work with and professional
