What we do

We fix problems with drains at hundreds of residential properties in London every month. Our work also includes commercial properties, such as offices, restaurants, schools, hotels and retail. As one of London’s largest drainage contractors, we’re experienced at resolving the problems that homes and businesses face in keeping their drain network clear, free-flowing and problem free.

Knowledge sharing and diagnosing

All our experts are reliable and professional. They’ll share their knowledge with you on-site so that you know exactly what’s going on at all times. This means you’re never in the dark, and you can make informed decisions for the best results. 

Our ability to diagnose and solve drain problems comes from 15 years of professional experience, and we’ve seen it all. For prevention tips, investigations and problem solving, our team is ready.  

Preventative maintenance 

Because we know the problems that commercial properties can face on a daily basis, we offer preventative maintenance contracts. Regular checks and cleaning will keep your drains working properly and help reduce the risk of blockages. How often you need them cleaning will depend on your property; get in touch with us today to discuss how we can help.

Surveying and mapping

Using high quality camera equipment, we can perform full mapping of drainage systems. This will highlight any problem areas and repairs that need attention. Mapping will provide a detailed plan of the network, including depth, location, and direction of the pipes. 

You’ll also be able to see the condition of existing pipes. All of this is vital information when planning and carrying out construction work on any property. 

We offer pre-purchase surveys for prospective home-buyers. CCTV cameras will show the condition of the property’s drains and pinpoint any potential issues. Repair costs can mount up and that isn’t ideal when you’ve just moved in. Remove the uncertainty with a drain survey. 


Internal drainage issues pose many inconveniences. As a fully accredited drainage contractor, all our tradespeople are equipped with the best machinery to tackle blockages in sinks, showers, toilets and baths. From toilet augers to drain rods, our experts have the right equipment to clear your drains of stubborn debris.

For those external problems, some more heavy duty equipment is required. Our engineers have rods, high pressure water jets and high velocity coring equipment which can tackle hardened cement, solidified construction adhesives, and more. 

Some of our accreditations

We’re fully trade accredited. Aspect is registered with the National Association of Drainage Contractors (NADC). When you book an Aspect drainage specialist you can count on getting the professional expertise you’re looking for.
