Blocked drains are one of the most common household emergencies in Portsmouth. Whether it's a kitchen sink that won't drain, a gurgling toilet, or water pooling outside, the companies listed above can help.
Drain problems in Portsmouth are often caused by the same issues seen across the Gosport, Fareham, Havant, Bishops Waltham area: fat and grease build-up, tree root ingress, and ageing clay pipework. A professional can diagnose and clear most blockages within the hour.
If your drain keeps blocking in the same spot, it may be worth asking about a CCTV drain survey. Several of the companies serving Portsmouth offer this as an add-on, typically costing £100-£200.
