I have given 5 star rating to Connor and his work team . Removal of unwanted flags done over a period of weeks which suited my needs . Very happy. Second agreed job to commence soon on replacing broken flags on driveway ,plus power washing . Connor has kept in touch regularly with me . Hasn't always been able to come when planned due to other circumstances. However I accept this as part of life etc . Connor always thinks of the customer's needs and given a good deal on price for work . Highly recommend.
