Had IWI help insulate a small work from home shed project. Ended up being cheaper than doing it myself and their crew, from estimate to installation, was friendly, efficient, and communicative. Would highly recommend.

Come in from the east! Docks suck to get into! You have to deal with a ditch drop off as your turning. There is two dock doors but one is blocked with the garbage bin.
Had a 9 am appointment and didn’t get to dock until 10 am! Guy didn’t touch my truck until 10:30 am! All the rest of intermountain places are quick to unload! There is parking available overnight along side the road.

I would NOT recommend this company! They left all doors on our home (new construction) open and I do mean open not just unlocked. They knew to lock since there was a code to gain entrance. I called furious since this could have resulted in the already installed electrical and HVAC equipment being stolen. The manager pretty much treated my call as insignificant and tried to shine me on. Then told me it's ok becasue a different person would be installing the ceiling insulation. Are you fricken kidding me. I was told the installer was mad because the builder wouldn't cut a hole in the floor to make the install easier. That is hearsay since I didn't hear it myself, but I would not recommend anyone use a company that treats the customer and their property like this. We all know how much property crime happens on new construction. Just the electrical and HVAC cost was about $50k and the manager acted like it was nothing. Well that's a lot of money to me and if that's the kind of work and workers they have I stay stay away from this company. To make it even worse the lack of care the manager displayed took my anger to a higher level. My thought is let me come to your house and leave every door open (and I do mean every door - sliders, front door, garage door) and see how you react. This company has no regard for their customers property. DO NOT USE!!!
