"JR Insulation is a great company!! They did everything from start to finish as promised, on time, polite, clean, and on budget. I can't recommend them enough. They also fixed a problem that I created in my own ignorance for free just to make me even happier. I told them it wasn't necessary but they insisted. JR's pricing was the absolute best for everything they did. Not the lowest bid but the lowest price to value, which in my opinion is the lowest bid. I would use they again, in fact, I would not use any other company for insulation or dry wall. Brian"

"They installed new insulation for us in an un-insulated attic space. They were well-priced, on-time, and very easy to work with. Workers all wore protective equipment and were both professional and friendly."

Customers say: True professional

"They did a very thorough crawl space clean up and detailed and well secured installation of the vapor barrier . They were honest, and efficient with positive energy. The issues are with communications from the office. They could be more professional, timely and thorough."

"When I bought my house it was discovered that rats had nested in my crawl space. The rats were long gone but the smell wasn't. Dillon and his crew came out and gave me a reasonable quote. They set up a fan to get the smell out until they could start the work. They went above and beyond cleaning out the old stuff, repaired vents that were coming apart and arranged to get new insulation installed. Super friendly and easy to work with."
