"Wonderful product and the insulation is working well."

"I am extremely satisfied with the quality of the work Raven Insulation performed in the process of spraying foam insulation in my 40 foot shipping container. They met and exceeded my expectations throughout the entire project. As a matter of fact, I have another insulation project planned in the near future in which I will definitely be utilizing Raven Insulation as the contractor."

"Went above and beyond to install the insulation."

"Needed to get my new shop insulated and called 4 States, their work was fast and efficient! The changes that the insulation made were huge!"

"John and Glen were very professional, they were prompt on taking care of my needs and the price was the lowest anywhere but didnâ t take away from the quality. Thanks for making my home warmer in the winter and cooler in the summer."

"Very experienced, if anyone needs spray foam done, please hire this company."

"I hired these guys to insulate my garage attic. They asked for a few photos and measurements, quoted a reasonable price, and scheduled the job right away. Friendly, professional, and hard working. I give them my highest recommendation!"

"The crew showed up every morning on time. They patched/drywalled and textured numerous small areas. The texturing was so good, that it is almost impossible to detect where the repairs where made. They also framed, drywalled and textured the kitchen area for recessed lighting installation. They repaired an area where there was a shower leak. They replaced the drywall and textured an area where a closet had been removed. On every part of the project, they exhibited superior workmanship. And at the end of every day, they cleaned up after themselves. Hire them again? Definitely yes!
