I highly recommend Platinum Plumbers. Last week we had a blocked sewer at our place in Frenchs Forest and found after clearing the line we had cracked clay sewer pipes under over our drive way (where tree roots were getting in). Not good! I first thought we would have to pull up the driveway, but the guys at Platinum had a solution to prevent this. After taking time to clearly explain what the "reline" is to me and my husband, they returned the next day and they used this fantastic equipment to reline the old clay pipes to prevent any digging and still making the old pipes new with a 20 year guarantee. Very impressive service start to finish.
