External Drain Gully Repair

What external drain gully repair covers

External gullies take a lot of wear from weather, ground movement and everyday debris. This service focuses on stopping leaks and restoring safe drainage outside the main property footprint.

• Inspection of the gully pot, grate, trap and connecting pipework
• Diagnosis of leaks, cracked fittings, movement and failed seals
• Resealing joints and renewing surrounding mortar or bedding as required
• Replacement of damaged gullies, grates or fittings where repair is not viable
• Clearance of local debris around the gully and flow checks after repair
• Practical advice to help prevent repeat issues (leaf build-up, silt, frost exposure)

When this service is the right fit

External drain gully repair is most useful when you notice:

• Persistent odours outdoors, especially after rain
• Pooling water near a gully or slow draining at the grating
• Damp patches on adjacent walls or wet ground around the gully
• Loose, rocking or sunken gully grates
• Visible cracks or gaps where pipework meets the gully

How the work is carried out

The work normally starts with an on-site assessment to confirm whether the issue is the gully itself, the seals, or the connecting drain. The gully is then opened, checked and repaired or replaced using suitable fittings for the existing drainage.

Where needed, small sections around the gully may be lifted to access pipe connections and rebuild a stable, watertight surround. The repair is finished with testing for leaks and flow, and the area is left clean and safe.

Aftercare and preventing repeat problems

Once repaired, keeping the gully clear of leaves and silt helps maintain good flow and reduces blockages. If the gully is exposed or connected to outside pipework, you may also be advised on simple weather protection to reduce frost-related damage. If there are wider drainage concerns, you will be told what the next sensible step is before any further work is agreed.
