Blocked Drain Clearing
Our fixed-price drain unblocking service starts at 80, with no additional charges or VAT. We use high-pressure water jetting and modern techniques to clear blockages efficiently. With over 16 years of experience, our team quickly resolves domestic and commercial drainage issues across Somerset.
Septic Tank Repairs
We repair and maintain septic tanks with expertise in soakaway issues, root intrusions, and grease build-up. Our solutions include comprehensive assessments and cost-effective repairs. Available across Somerset, we address both domestic and commercial septic tank requirements with professional reliability.
Sewage Treatment Plants
We install Environment Agency approved sewage treatment plants built to BS EN 12566-3 standards. Our UK-manufactured systems include 25-year structural guarantees and come with comprehensive installation support. Ideal for properties requiring compliant wastewater management solutions across rural Somerset.
Camera Surveys
Using advanced camera equipment, we inspect drainage systems to identify blockages, collapses, and structural issues. This non-invasive technique provides accurate diagnostics for targeted repairs. Available as a standalone service or free with repeat drain unblocking cases.
Emergency Callouts
Our 24-hour emergency service responds to urgent drainage issues across Somerset. While standard unblocking costs 80, emergency pricing varies by location and time. We prioritise rapid attendance while maintaining transparent pricing and professional service delivery standards.
