9/10

Nice Team, they are fast and professional. Mine was a small project compared with what they use to do. I had some issue after a year but was fixed soon. I would recommend Duralock for your projects.

I contact GNI for a quote. Some days after, Mr Armstrong came and made the measurements and the day after I received the quote. After pay the deposit, the crew came and replaced my old insulation for the new one. I consider the job was well done. Fast and easy to pay by Credit Card. I received the Invoice by e-mail. No issues at all. I fully reccomend GNI
