There are many signs that show your drainage may need a patch repair. One of these signs is a strong, horrible smell coming from your sewage system. Another sign is that your drainage system may be slower than normal as the pipes may be cracked or degrading. Additionally, you could notice backed-up sewers, which are caused by collapsed drains or signs of rodents or mould patches in your home. The best way to identify and fix this problem is by doing a CCTV drain survey, which we can offer as a service.
