We deliver dependable, professional drainage services to both homes and businesses. Whether you are facing an urgent blockage, a recurring drainage problem, or need a full inspection of your underground system, we provide expert support with rapid response times and lasting solutions.
Our experienced drainage engineers are trusted for their fast service, quality workmanship, and attention to detail. We’re available 24 hours a day to resolve any drainage issue with minimal disruption to your property or routine.

If you’re experiencing blocked drains, unpleasant odours, recurring pipe issues, or surface water problems in Dorchester, our specialist drainage engineers are here to help. We provide reliable, efficient drainage services for homeowners, landlords, rural properties, and commercial premises across Dorchester and nearby Dorset villages.
Using modern equipment and proven repair techniques, we resolve drainage problems quickly and provide long-term protection for your property.
Blocked drains can cause internal flooding and significant disruption. We provide rapid-response drain clearance across Dorchester, resolving blocked toilets and bathrooms, kitchen sink and waste pipe blockages, overflowing inspection chambers, external rainwater and surface drains, and commercial drainage systems. Our engineers use professional mechanical tools and high-pressure water jetting to restore flow efficiently.
Persistent or unexplained drainage issues often require a detailed inspection. Our CCTV drain surveys allow us to examine pipework internally and detect cracks and fractures, tree root ingress, collapsed or displaced sections, silt and debris build-up, and age-related pipe deterioration. We provide a clear diagnosis and recommend cost-effective repair options.
For stubborn blockages and heavy deposits, our industrial jetting systems thoroughly clean pipe interiors. This service is particularly beneficial for older properties in Dorchester where scale build-up and debris accumulation can restrict flow.
If structural damage is identified, we offer both excavation repairs and trenchless relining solutions. Drain relining strengthens pipes internally without large-scale digging, making it ideal for driveways, gardens, and listed properties. Where necessary, we carry out targeted excavations with minimal disruption and professional reinstatement.
Our drainage services extend across:
We also serve surrounding rural properties and villages throughout the Dorset area.

“Had an overflowing blocked drain at the side of my house – rang around a few drain companies in Bristol that couldn’t come out on the day, rang Trent’s and they arrived within a few hours to clear it. Really friendly guys turned up and didn’t charge the earth either! Highly recommended.”
”Would definitely recommend Trent’s and use them again. I had a blocked drain with an access problem. They were recommended to me after Dyno Rod and another firm couldn’t resolve the problem. Very helpful from the start. Really responsive, quick and good communication throughout.”

We understand the drainage challenges linked to Dorset’s older housing stock, rural properties with septic systems, and clay-based soils.
Many properties in Dorchester experience:
Addressing these issues early reduces the risk of structural damage and costly repairs.

Get answers to common questions about our drainage services and expert advices
The cost of clearing blocked drains in Dorchester varies depending on the severity and location of the blockage. At Trent’s Drains, we offer transparent pricing with no hidden call-out fees. Most standard drain unblocking jobs range from £80-£150. We provide free quotes and will always discuss costs before starting any work. Emergency callouts are available 24/7 at competitive rates.
We understand that drainage emergencies can happen at any time, which is why we operate 24/7 across Dorchester. Our goal is to respond to emergency callouts within 60-90 minutes in most cases. We keep our team on standby throughout the day and night, ensuring you’re never left dealing with flooding, severe blockages, or drainage failures on your own. Our rapid response is available across Poundbury, Fordington, Charminster, Maiden Newton, and all surrounding areas.
Blocked drains are commonly caused by a buildup of grease, fat, and oil poured down kitchen sinks, hair and soap scum in bathroom drains, wet wipes and sanitary products flushed down toilets, and tree roots infiltrating older drainage systems. In Dorchester, we also see issues from aging pipework in certain areas. Other causes include collapsed pipes, improper pipe installation, or foreign objects accidentally flushed or washed down drains. Regular maintenance and careful disposal of waste materials can help prevent most blockages.
Yes, we strongly recommend regular preventative maintenance to keep your drains flowing freely and avoid costly emergency repairs. Our maintenance services include scheduled drain cleaning, high-pressure water jetting to remove buildup, CCTV drain surveys to identify potential issues before they become serious, and root removal treatments. For homes and businesses in Dorchester, we can set up annual or bi-annual maintenance plans tailored to your property’s needs. Prevention is always more cost-effective than dealing with emergency blockages.
A CCTV drain survey involves inserting a specialist waterproof camera into your drainage system to inspect the interior condition of pipes. The high-definition footage allows us to identify blockages, cracks, root intrusions, collapsed sections, and other issues without excavation. You might need a CCTV survey if you’re experiencing recurring blockages, buying or selling a property in Dorchester, planning an extension or renovation, or simply want to check the health of older drainage systems. Many Dorchester properties have aging pipework that benefits from regular inspection.
Absolutely. All our drainage engineers are fully qualified, trained, and experienced in all aspects of drainage work. We carry comprehensive public liability insurance and employers’ liability insurance, giving you complete peace of mind when we work on your Dorchester property. Our team regularly undergoes training to stay current with the latest drainage technologies and best practices. We’re also registered waste carriers, meaning we can legally and safely dispose of any waste removed from your drains in compliance with environmental regulations.
Yes, in many cases we can repair damaged drains using trenchless (no-dig) technology. This includes patch lining, which creates a new pipe within the existing damaged section, and drain relining, where we insert a resin-coated liner into the pipe that hardens to create a durable new pipe interior. These techniques save significant time and money compared to traditional excavation, minimize disruption to your Dorchester property, and are ideal for drains beneath driveways, gardens, or buildings. We’ll assess your specific situation with a CCTV survey and recommend the most suitable repair method.
Yes, we stand behind the quality of our work with comprehensive guarantees. Our standard drainage repairs come with a 12-month workmanship guarantee, while drain relining and patch lining typically carry extended guarantees of up to 10 years depending on the specific work carried out. All guarantees are provided in writing, and we’ll clearly explain what’s covered before we begin any work at your Dorchester property. Our commitment to quality means we get the job done right the first time.
We accept a wide range of payment methods to make things convenient for our Dorchester customers. We accept all major credit and debit cards (Visa, Mastercard, American Express), bank transfers, and cash payments. For larger projects, we can also arrange payment plans to spread the cost. Payment is typically due upon completion of the work, and we’ll provide a detailed invoice showing exactly what work was carried out. We never ask for large upfront payments, and there are no hidden charges—our quotes are transparent and comprehensive.
