What We Can Clear for You in Chertsey

ASL clears and cleans drainage systems from 100mm and 150mm drains through to larger pipework, culverts and piped ditches. Our work includes outside drains and gullies, manholes and inspection chambers, soakaways and surface-water systems, as well as ground-floor blocked toilets and kitchen wastes, across Chertsey and the surrounding areas including Addlestone, Ottershaw, Lyne, Thorpe and Laleham. For commercial premises, clearing the immediate blockage can also be the start of planned cleaning and maintenance, so busy sites are not simply left until something fails.

Toilets

Backing up because of an outside drain blockage, not internal plumbing.

Ground-floor sinks

Draining slowly or overflowing due to blocked external pipes.

Manholes & chambers

Inspection chambers in the garden or driveway that have surcharged.

Downpipes & gullies

Rainwater downpipes and gully outlets that won't clear.

Soakaways

Systems that aren't draining water away as they should.

Commercial drainage

Foul and surface water systems for businesses of any size.

Why Do Drains Get Blocked?

Chertsey sits on Thames terrace gravels close to the floodplain, with clay lying underneath. That combination means the ground holds a lot of water after prolonged rain, and drains that cope fine in a dry summer can start struggling once the water table climbs in winter. Period cottages near the historic centre, along with newer estates further out, mean pipework here varies a lot in age and condition, and the older sections are particularly prone to root ingress from mature garden trees. The M25 has also brought plenty of commercial and light industrial development over the years, and ASL’s out on those sites just as often as on residential streets.

Kitchen habits

Fat, grease and food waste hardening inside the pipe.

Bathroom items

Wet wipes and sanitary products, even 'flushable' ones.

Nature

Tree roots, silt and leaves finding their way in.

Wear & tear

Scale build-up, cracks or old pipe materials failing.

Build issues

Renovation debris or pipes laid at the wrong gradient.

How We Fix It, Our 5-Step Process

  1. Call and rapid response Describe the issue, and an engineer is dispatched to your Chertsey address, normally the same day, subject to availability.
  2. On-site diagnosis The engineer identifies what's causing the blockage before choosing the most effective method, using a CCTV look-see where the cause isn't obvious.
  3. Clearing the blockage High-pressure jetting, rodding or mechanical drain milling, chosen to suit the pipe and the problem.
  4. Confirming the fix Once your drain is flowing freely we show you the evidence, and where appropriate carry out a complimentary 10-minute CCTV look-see to check nothing more serious is hiding further down the line.
  5. Reporting and next steps If additional work such as no-dig lining or a localised repair is genuinely needed, we explain the options clearly and provide a free, no-obligation estimate.

Chertsey Case Study

Recent Drainage Work In Chertsey

We were called to a property in Chertsey where the downstairs shower and washbasins gurgled whenever the toilet was flushed, with water starting to stand in the shower. Our engineer Darren traced the problem to a blockage and cleared it using rods, with sanitary products recorded as the cause. Once cleared, the drainage was flowing again and no further work was recommended. Read the full case study on our Chertsey case study page.

Having found ASL Limited on multiple recommendation sites I can see why - they have been a pleasure to deal with from start to finish! To assist with investigative works we had Mark and Alex out initially and then Ryan and Max out for further work - both teams were an absolute pleasure to have at our house: polite, punctual and most importantly they were experts in their field. ASL rightly have an excellent reputation as I would not go anywhere else if I need any future help!

We had a blocked drain. Darren attended and confirmed that the blockage was beyond our boundary therefore not our responsibility. Thames water attended and refused to accept it was their issue. Darren returned and promptly cleared the drain for us. He was polite efficient skilled and hard working. We strongly recommend ASL for drainage work.

What a great service! Booked in when I needed it, turned up exactly on time, investigated and sorted the problem and I now have free flowing drains! Then, to cap it all, they wouldn't take my money and said 'we'll invoice you later'. Now that's how to inspire trust! Would I use ASL again? I'm hoping I won't need to but I'll be recommending them everywhere I can!

An outstanding company. Professional, responsive, honest and knowledgeable. A private treatment plant that continually malfunctioned (electrics installed inside the tank. What genius thought that was a good idea?!) has been completely upgraded by ASL. Trenches dug, bespoke risers made on site, new electrics installed, the lot - all done with care and expertise. I cannot recommend them enough. Every single one of their staff are a credit to them.

FAQs

How quickly can you get to me in Chertsey?

Same-day attendance is normally available, subject to engineer availability and workload. Once an engineer is on site, most blockages are cleared within 30 to 45 minutes.

How much does it cost to unblock a drain?

It varies with the type of blockage and the equipment involved, but you'll always get a free quote before agreeing to anything.

Who's responsible for the drain, me or the water company?

In Chertsey, Thames Water generally covers the public sewer network. Anything within your own property boundary is down to you. If you're not sure which applies, ASL can help work it out.

Do you offer emergency callouts at weekends?

Yes. Weekend callouts are covered across Chertsey for anything that genuinely can't wait.

What's this complimentary CCTV look-see, and is it the same as a full survey?

Every blocked drain callout in Chertsey includes a complimentary 10-minute CCTV look-see as standard, so you can see roughly where the problem lies. A full CCTV drainage survey, with a detailed written report, is available separately for more complex jobs.

Can you fix a drain without digging up my garden?

Frequently. No-dig repairs and lining solve most problems without touching the garden, but it depends on what the survey reveals.
