Drainage Refurbishment & Upgrades

If your drainage system is ageing, repeatedly blocking, or no longer fit for purpose, a full replacement isn't always the first or best option. With the right inspection and targeted works, refurbishment and upgrades can restore performance, reduce emergency call-outs, and extend the life of your system, with far less disruption than excavation.

ICE Drainage delivers professional drain refurbishment and upgrade works across London and the Home Counties, supporting hospitality venues, facilities managers, contractors, and property teams.

What do we mean by refurbishment and upgrades?

Drainage refurbishment and upgrades are planned works designed to improve how your system performs, without necessarily replacing everything. Depending on what we find, this can include targeted repairs to damaged sections, replacing defective gullies, channels, or access points, improving falls and flow routes where practical, lining or patching to seal defects and prevent water getting in, upgrading pipework or connections during a wider refurbishment project, and improving drainage around high-risk areas such as kitchens, plant rooms, and loading bays.

The goal is simple: reduce failures, improve flow, and minimise disruption.

When should you consider drainage refurbishment?

Refurbishment and upgrades are often the right move when you're experiencing repeat blockages in the same areas, a CCTV survey has shown defects such as cracks, displaced joints, or deformation, root ingress keeps returning, pipework is heavily scaled or corroded and flow is restricted, you've had internal flooding or manhole surcharging, or you're planning a building refit and want to upgrade drainage at the same time.

If you're not sure whether you need refurbishment or just maintenance, we can advise based on symptoms and inspection results.

Common problems refurbishment and upgrades can solve

Planned drainage improvements can resolve or reduce persistent slow drainage and repeat call-outs, localised collapses or damaged sections, root ingress through weak joints, poor access from missing or poorly positioned rodding eyes and manholes, defective gullies and channels causing surface flooding, and high-risk areas where grease or sludge builds up quickly.

For commercial sites, the biggest win is often reducing downtime and emergency incidents.

Our refurbishment and upgrade process

We keep it structured and evidence-led.

1) Site assessment and history

We gather details on recurring issues, operational constraints, and access.

2) CCTV inspection and diagnosis

We recommend using CCTV to identify defects and entry points for roots, areas of restriction from scale, corrosion, or build-up, the pipe material and condition, and where repairs or upgrades will have the biggest impact.

3) Clear recommendations and scope

We provide a practical plan with options, prioritising what will deliver the best performance improvement.

4) Planned works and delivery

We carry out the agreed refurbishment or upgrades with a focus on safety, quality, and minimal disruption.

5) Verification and next steps

Where appropriate, we confirm performance and advise on maintenance to protect the investment.

Refurbishment and upgrades for commercial and hospitality sites

Commercial drainage needs to work reliably, especially in hospitality, where downtime can hit service and revenue. We commonly support hotels, pubs, bars, and restaurants, commercial kitchens and food sites, schools, colleges, and public buildings, retail units and shopping centres, managed estates and multi-site portfolios, and facilities management teams and contractors.

We'll plan work around operational requirements wherever possible.

Upgrade opportunities during refits and refurbishment projects

If you're already refurbishing a site, it's often the best time to address drainage issues. Common upgrade opportunities include replacing or improving kitchen drainage routes, upgrading gullies, channels, and floor drains, improving access points for future maintenance, addressing historic defects discovered during a strip-out, and building in a planned maintenance approach after the refit.

If you're a contractor or facilities team managing a programme of works, we can coordinate around your schedule.

Refurbishment versus maintenance

Maintenance is regular cleaning and unblocking to keep systems flowing, such as jetting, grease removal, and planned cleans. Refurbishment and upgrades are about fixing defects and improving system design or access to reduce failures long-term.

In many cases, the best outcome is refurbishment combined with a sensible maintenance plan afterwards.

What to do next

If you're considering refurbishment or upgrades, list the areas where issues keep occurring, gather any previous CCTV reports or job history, consider operational constraints such as service hours, access, and shutdown windows, arrange a CCTV inspection if you don't have a recent one, and contact ICE Drainage to discuss your options.
