Services
Plumbing
Our comprehensive plumbing services cover installations, repairs, and maintenance for residential and commercial properties. From leak detection to full system upgrades, our Gas Safe engineers use advanced diagnostic tools to ensure leak-free, efficient systems. We specialise in both traditional and modern plumbing solutions, providing durable installations that comply with current building regulations while minimising disruption to your property.
Boiler installations
We offer boiler replacements and installations with manufacturer-backed guarantees. Our engineers assess your property's heating requirements to recommend the most energy-efficient models. All installations include system flushing and magnetic filter fitting to extend boiler lifespan. We handle gas connections, flue positioning, and electrical integration, ensuring safe, compliant operation while maintaining eligibility for extended manufacturer warranties.
Drainage
Our drainage specialists tackle everything from minor clogs to major pipe failures. Using CCTV inspection technology and high-pressure jetting equipment, we identify and resolve blockages caused by tree roots, grease build-up, or collapsed pipework. Emergency drainage services restore functionality quickly, while preventative maintenance plans help commercial clients avoid costly disruptions through regular system assessments and cleaning.
Emergency call-out
Available 365 days a year, our emergency service addresses critical plumbing issues like burst pipes, heating failures, and severe leaks. We prioritise same-day attendance for heating emergencies during cold weather, with engineers carrying essential spare parts to resolve common faults immediately. Our rapid response team maintains full diagnostic equipment to assess and repair issues efficiently, minimising property damage and restoring essential services.
Powerflushing
This specialist service removes sludge and scale from central heating systems using high-velocity water flow. We recommend powerflushing for systems with cold radiators, noisy boilers, or reduced efficiency. The process restores optimal circulation, extends component lifespan, and maintains boiler warranty validity. Our engineers include system inhibitor treatment post-flush to prevent future corrosion, ensuring long-term heating efficiency.
