The lad was so helpful, did an excellent job was on time, and I was extremely surprised at the amount I was quoted when job was completed. I was quoted a rediculous price by another Company $7900. Pays to shop around and I found G A Perry who I shall continue to use in future. Thankyou.. Valda Gainford

Had an issue with a Gas Leak, called three 24hr Emergency repairers and the only one to answer the call was GA Perry. From the outset, they were professional and had a tech arrive within 2 hours as promised. After explaining my situation to the tech, he troubleshooted all possible areas of the issue. He had the issue resolved within 30 minutes, could not be happier with the service, 5 stars. Highly recommend.
