Wow talk about the poster child for clean and dry gutters. This stuff is the cats meow. Thanks so much for putting the increased heat cables in {VersaScreen IceBlaster Pro}, they worked fantastic. The rest of the house is hung like Doctor Zavargo house in Russia but not the back - all the gutters are snow and ice less.

Hi Greg, just wanted to follow up with you regarding the work you did at my Brookfield ranch house last summer . As you recall we had significant ice dam issues over the front door of the house when we bought it. The dam was 5-6 feet back on the roof and I estimate 15-18 inches deep at its peak. We also had Ice dam issues over our sun room addition. Over the summer you suggested cutting in a ridge vent and then add your roof heating system and gutter guards. (I also added blown cellulose insulation.) We all agreed this was the best approach and we began to install.

Over last winter we had zero ice dam issues over the front door or sun room. We could actually see the snow melting down the valleys and could hear the rain gutters dripping with melted snow . We are believers that by adding your valley and rain gutter heating system we had an ice dam free winter.

Please feel free to use us as a reference for those who have questions.

Hello Greg, Just a quick follow up.The system is working flawlessly !! Rear gutter always clear. Front gutter currently with ice dam. I took some pictures and I'm not sure if you need any more testimonies but I am willing.

Greg, Just made payment online. Your guys do exceptional work! Thank you for your personal customer service, I am sure you are aware how lucky you are to have such an outstanding team. The electrician treated my home like it was his and cleaned up after himself, almost like my dad/brother was doing the work for me. Great job!!!

GSB Services is outstanding. In the middle of the 2012/13 winter, my ice dams were removed and the heater technology installed that finally, after 15 years, ended the dams. I am currently in discussions to add additional heater sections for other areas of my house. Professional and courteous, and I can recommend GSB Services unconditionally to anyone who wants roof heaters that work wonderfully.

"I had GSB install the Ice Blaster Pro system in the rear upper gutter in my home. I had terrible problems with ice dams in this area in the past. Now the gutter is clear and I have zero issues with ice dams in this area. I have enclosed picutures taken the same day of the rear gutter and the front gutter in which I did NOT install the system. Clear ice damming in the front. The system works as promised and the entire experience was very professional with excellent work performed along with great communication. I would highly recommend this system for any homeowners who are experiencing ice damming problems."
