I contacted Great Barriers Security and Privacy for a quote on a screen door, and once they had viewed my request, Shay booked an appointment to come out and do a measure and quote. Other operators did not even bother to suggest a measure, and just provided a standard quote for a non-standard door. Shay’s professionalism left me in no doubt that this was the company that I would be using, and I am looking forward to the finished product

I can't appraise Shay enough for his amazing help with our automatic gates. Saved me! When we had a automatic gate malfunction Asked another gate repairs company to help us out, they said that we need a new system! $5000 or more! Shay not only fixed our gates but also showed me how to fix the problem. We manage a gated community and Shay helped us within hours, several times! Your a great help Shay, thank you! Regards Cass, city view villas!

Great barriers security supplied us with a quote for replacement and installation of all our screen doors to our home with the new security steel mesh doors. We went ahead with the job, and were very happy with the service. Not only has it added security to our home, but i have found they are much more cleaner than the old mesh ones, and so easy to clean by just simply wiping them down. Their prices are very competitive, and we would highly recommend their services to anyone.
