- NMNaomi ManahanAug 20, 20265.0Nothing but great things to say about Josh, Tory and Dewayne. They installed insulation in our 90 year-old home with zero complaints and lots of creativity to get the insulation in all the nooks and crannies possible. Would gladly hire them again.
- TCTC CEHAug 3, 20261.0Contacted the company twice because they installed my gutters on my house before. Never heard back from company. After contacting the third time was informed they don’t do home owners installations anymore. Thanks for wasting my time. Probably best stay away from this company.
- DBdonna boyerJul 30, 20265.0GTG repaired the gutters on my house and installed attic insulation. Job was done promptly and to all my specifications. Tony, Dewayne and Joshua worked in this terrible heat and did a fabulous job. Kudos to them for their work ethic. I am very pleased with the work done by GTG.
- MCMary CallahanJul 6, 20265.0Larry, Key, and Josh braved my attic on a Columbia July day to remove very old insulation, seal, & blow in new. Larry & Key also replaced subfloor insulation. The team was hardworking, experienced, diligent, & respectful of the property, me, & each other. I highly recommend GTG.
- JPJennifer PetersonApr 5, 20265.0Josh was great to work with, I reached out for insulation removal and installation and within a week, he came by, got me a quote quickly and scheduled the work on a day convenient to me. Gabriel and Josue were on time, very professional, and did a great job. I couldn’t be happier with my experience and would work with them again.
