If I could give Aaron (the owner) more than 5 stars I absolutely would! Impeccable service from start to finish. I found out about AGF through a friend & when approaching them I was impressed by the quotation given to us for the amount of work that we needed doing, thought maybe it was too good to be true at first, but it wasn’t - we certainly bagged a bargain! High standard finish to our property for a fraction of the price my neighbour paid for hers, she even commented that ours look much better than hers do, bonus! Aaron was professional throughout and is a lovely & down to earth person. We asked if we were due a roof replacement due to a leak we had, he was honest and told us we already have a good quality roof that just needs a small repair, I’m sure many tradesman would have jumped at that opportunity to overcharge us for something we didn’t need, but he didn’t do that & was honest in his advice throughout & carried out the work to a high standard. I was impressed that as the owner that Aaron does the main bulk of the work himself, in my experience the owners tend to leave the grafting to the employees but he gets stuck right in there and is definitely a perfectionist with his work. He’s informative to his clients and answers questions (and I had many questions), he’s pleasant and friendly and even had the approval of our 4 year old who never talks to anyone! The work was completed in a timely manner, to a perfect standard, for a great price. He even did extra for me like using leftover cement to stick back a step on the front garden that had come loose, plus other small jobs. Absolutely lovely guy who goes above and beyond for his customers, and I’d certainly recommend him to anyone. Will definitely be calling him back for anymore work we need doing. If you’re looking for a builder and in 2 minds about how to choose - choose this one, you won’t be disappointed! Thanks Aaron!
