ABOUT MSJ
Drainage and property maintenance, run out of Streatham.
Who we are
Five accreditations. One freephone. 15 areas covered.
MSJ Drain Clearance Ltd is a drainage and property-maintenance company based at 258 Amesbury Avenue, Streatham · SW2 3BL. We cover Central London through to Crawley and Bromley — 15 core areas across the South.
We hold five trade accreditations — Constructionline Gold, CHAS, Environment Agency, SafeContractor, and UKATA. The same standards we bring to a commercial site are the standards we bring to a kitchen-sink callout.
Our work splits roughly half-and-half between domestic emergencies — blocked drains, burst pipes, sewage backups — and commercial groundworks where the accreditations matter most. Whichever way you find us, you get the same answer: a real engineer on the phone, on-site fast, and a written quote before anyone lifts a tool.
Accredited to commercial-contractor standards





What the badges mean
Five accreditations, explained.

Constructionline Gold Member
The highest tier of Constructionline's pre-qualification scheme — covers financial standing, insurances, health & safety, environmental management, anti-bribery and quality. Required by most local authorities and main contractors before they'll consider you for a job.

CHAS Accredited Contractor
The Contractors Health and Safety Assessment Scheme — independently verifies our health and safety policies, training, and incident records. Widely demanded for any work on commercial premises or council property.

Environment Agency Registered Waste Carrier
Anyone moving waste off your property has to be registered. We are — which means construction spoil, drainage material, and excavated soil are handled lawfully end-to-end.

SafeContractor Approved
Independent health and safety audit from Alcumus. Renewed annually. Recognised by most facilities-management procurement teams.

UKATA Asbestos Awareness Trained
UK Asbestos Training Association certification. Required for any trade working on properties built before 2000. Annual refresher training, certificates on request.
