"Torsten, the owner was great! He diagnosed our problem areas and gave us recommended solutions. He worked within our budget and even broke it up into bite size pieces. This way we were able to make some fixes to our insulation, then if that wasn't good enough, he could keep doing more until our house had a good climate. We may not even need to do the rest of the insulation work (which might run several thousand dollars) because Torsen made such good suggestions on less expensive alternatives ... and then did the work so well.
His son was the actual installer of the spray foam in our basement. He was professional, kind, and highly attentive to details. Absolutely delighted with him.
After the work was done, PK Wadsworth (the heating company that recommended we improve our insulation and recommended Pure Seal) inspected the work of Torsten and his family. They were pleased but found one small area that Torsten missed. It was trivial, but both PK Wadsworth and Pure Seal are perfectionists. So they called Pure Seal back and asked them to add some more insulation under the stairs. Pure Seal came right out, looked at the problem area (and even identified a second small area that they missed ... and I would have never even noticed these small imperfections !)
Torsten fixed everything pronto. It was all done perfectly.
I do not give a great review lightly. But please trust me and hire Pure Seal !!! Just tell Torsten your budget ... and feed him some cupcakes ... he will try to find the least expensive way to fix your problems. He knows what he is doing ! He is very honest and won't over sell you ! He is also kind, and hard working. His whole company is great !
I wish every contractor was this good !

"The attic insulation and other tasks were done in less than an hour. All indoor work was completed. Outdoor work was deferred due to cold weather. Work was performed as promised. After paying the bill, Jerry called back right away and informed us of an over payment. He had a check in the mail the next day.

"We purchased the Angie's list deal of $250 for $600 of blown-in insulation. Sean was responsive and came to the house to check it out. We wanted to address a lot of cold air inflow was coming from an attic space on the 2nd floor of our home. They ended up adding some insulation and vapor barriers in the attic space, and we also paid another $200 to add some insulation in our basement where Sean thought there was a need. Overall very professional and helpful looking at lots of spaces across our house to opine on what would be most beneficial to us. We have noticed a big difference on the 2nd floor - it's a lot warmer up there."

"We received an estimate soon after we contacted Jim at North Coast Insulation and Ventilation.. The estimate was detailed and covered all the work required. The work was completed efficiently and professionally on the day it was scheduled. We have noticed a big difference in our heating efficiency and would recommend this company highly. We did not get a second estimate so have nothing to compare pricing but feel it was well worth the money that we spent.

"Thinking I had an insulation issue because icicles were forming on on gutter, I got estimates from 3 companies. Ray Sabin, PM at NRG stated that my issue was the gutter not insulation. Ray is an honest vendor that will not sell you unnecessary services and products."

"The company was very supportive and accommodating. They took their time during the initial visit to review our attic before supplying a competitive quote which we accepted. They stuck by the quote during the completion of the job even though part of the attic required some additional insulation. Both Jose and Sergio were extremely thorough and professional. I will definitely recommend them to others without hesitation."

"My wife and I attended a presentation by James Manfield, the owner of GreenForce. We were impressed with company product and Jame's punctuality, professionalism and honesty. We decided to hire his company to add insulation to attic of my in-laws house. The installers came on time and over 9 hours managed to complete 95% of the job. The installers were polite, professional and clean. The subsequent installers came next day and completed the job. We are very pleased with James and the service provided by his company. As FYI, we had similar radiant barrier installed by another company in our own house in 2012 and we were pleased with the reduction in heating and cooling cost."
