R-Value Insulators LLC (RVI) - Rhinelander, Wisconsin

Excellent experience, the scope of work was much broader than quoted. The job was done once it was "done right", even though that meant plumbing, hvac, electrical, and even concrete work. The price was very fair and I will be using RVI again if I need any insulation work performed.

As a builder, I strive to construct homes to a high standard of quality. In my opinion, this mentality goes deeper than what can be physically seen upon completion.
I've used RVI for all my projects, and their knowledge and workmanship is second to none. I know this to be true, because blower door tests do not lie.
I've never had a client complain about low energy costs or being comfortable.
You have one chance to do it right; give these guys a call.
Would highly recommend

The presence of Sam and his crew during insulation was a pure delight. The job they did on every part of our building was excellent. Now that we live here we are amazed at how quiet it is in our place even during storms. It's a new build so cannot compare costs to before RVI but heating costs compared to previous older home are much less. So thankful and blessed to have worked with RVI.

RVI is an industry leader in advanced insulation technology, including the caulking and bath ventilation. Sam is an owner of the company and helps develop new insulation technologies, such as using tyvek on basement walls that go against concrete and bath fans specially designed to go on soffits so no holes were needed in my steel roof.

The state inspector was highly impressed with RVI's job when he did his insulation inspection.

RVI was half the price of another firm that wanted to spray foam my entire house. Putting spray foam on the bottom of my roof deck would not only have been much more expensive, but it would not be as good of a solution do to different thermal expansion rates of wood and foam.

I highly recommend the RVI team. I am very happy I found an insulation contractor in northern Wisconsin with high quality and great value.
