Commercial Drainage in London and Hertfordshire
Drain 365 is a commercial drainage company serving businesses, landlords and facilities teams across London, Hertfordshire and Bedfordshire. Since 1998 we have kept kitchens trading, washrooms open and car parks dry with a mix of planned maintenance and rapid emergency response, 24 hours a day, 365 days a year.
Whether you manage a single restaurant or a portfolio of offices, our engineers deliver the full range of commercial drainage services, including:
Planned Drain Maintenance for Commercial Premises
Most commercial drainage emergencies are not sudden. They are slow build-ups of grease, scale, silt or debris that finally tip over under pressure, usually at the worst possible moment. A planned maintenance programme catches these problems early, during a scheduled visit, rather than at 3am with a flooded kitchen.
A Drain 365 maintenance contract is built around your site. We agree a visit frequency based on how hard your drains work, carry out high-pressure jetting and descaling where needed, inspect the system with a camera, and leave you with a written report and photographs after every visit. If anything needs repairing, you get a clear quote before any work starts, never a surprise on the invoice.
For most sites this means fewer call-outs, lower annual spend and a drainage system you no longer have to think about. Read our guide on how often commercial properties should have a drain survey, see our commercial drain maintenance service, or call 0800 699 0922 to discuss a programme for your premises.
