    I am very pleased with your staff, they all seemed trustworthy, know what they are doing, friendly, and above all, your price is reasonable. I have already recommend a few pals to your Company.

    Had a wonderful experience with this company. Excellent communication. Staff was great to work with. Special thanks to Dan and his crew who stayed late into the evening to finish the job. Would definitely recommend these guys!

    From quote to completion of the job, very professional. Brendan and Keegan were polite and friendly. Explained exactly what they were going to do (which was as per the quote I had received from Mike the Sales Manager). Excellent work; I would recommend GNI to anyone who wants a worry-free job to be done in their home.
