High quality service. Spoke with Russell on the phone, he was super helpful and took his time explaining to me and my family all the aspects of the job. The team was quick and worked efficiently. Would highly recommend!

There are not enough words to convey the awful experience we received from this business, particularly the owner Brian. My mother hired Guardian as a gift to me and my fiance on our first home, just a week before our first baby was due. The work was scheduled to be done on a Thursday & Friday (baby due the following week). She notified me the morning of, super excited for this to be done. Brian's crew came on Thursday and put the holes in the home for insulation to be blown on Friday. First off, they found walls with insulation and did not say anything at first until questioned to remove this from the price. Second, they left a huge debris mess in our yard. They did not come back on Friday due to an "unforeseeable issue" the team had. Well... Saturday they came back and did not finish (Saturday was also a day we had other contractors coming, which is why we scheduled the work to be done Friday). Sunday they finally finished which ended up being the same day we went into labor. SO much more went on that would take up pages to explain. Needless to say, the worst part of this experience was the HORRIBLE ethics and professionalism from the owner Brian. He was extremely rude and expressed that the customer should be open to flexibility even when they schedule works to be done. He questioned his customers and was counterintuitive every step of the way and only cared about getting paid for a job BEFORE it was done and when it WASNT done when agreed to.

As a non-expert in the insulation business (since I don't understand R values) I asked the owner to list on the quote the depth of the insulation when the job was done. He did so, but when the job was done it was well below (up to 2-3 inches) that in most areas. It took an hour of arguing with the owner on the phone (mostly with him blaming me for the discrepancy) to get him to live up to the contract which is why he's getting 3 stars and not 5. The workers were great and did a clean job, but the owner struggles with customer service. I wouldn't do business with him again or recommend him to friends.

I had the blown in insulation done on my home and I can't believe how effective and how much I am saving on my electric bill. They had the best price and they matched the paint on the outside walls so well you can't see anything was done!
