Great!
Jorge and Emmanuel were very professional and did a great job cleaning out all of my old insulation. They had my attic cleaned in no time at all. I would highly recommend them.
Great Job. Fast and efficient! Arrived when they said. Very tidy and respectful. I had several inches of cellulose over fiberglass bats. They were able to vacuum both types of insulation with their innovative system. I will be calling them back when it's time to replace the insulation!
Provide great consultation on attic insulation. Good communication for scheduling and work progress. Pricing very good. Very satisfied with HiProvac service
I had a mess in my attic after reroofing ... insulation mixed with wood shingles. Hi-Provac was quick to respond with an estimate for removal and reinsulation that was very competitive. They showed up on time and completed the work as promised. I was amazed at how clean the process was. I was expecting to clean up behind the work but that wasn't necessary. Their folks were highly professional and friendly. If you need insulation removal and or new insulation, I highly recommend Hi-Provac.
We Just had Hi-Provac come out and insulate our 4 square house in SE Portland - Attic space and walls . Very happy with their work . Very professional and communication about what was to be done was great . I would highly recommend them . Good clean up too.
