Areas we cover in Gloucestershire

OneFlow Drainage provides drain unblocking services across the entire county of Gloucestershire. Our coverage includes all six districts:

Gloucester

As the county's only city, Gloucester keeps our engineers busy year-round. We regularly attend properties across the city centre, Quedgeley, Hucclecote, Longlevens, and Barnwood. The city's rich history, from Roman origins to Victorian industrial expansion, means drainage systems of every era.

The historic Gloucester Docks area and the medieval streets around the cathedral present particular challenges, with centuries-old drainage that's been modified and extended many times. We're experienced with the complex layouts typical of this historic city.

Cheltenham

The elegant Regency spa town of Cheltenham requires careful handling. We attend properties across the town centre, Montpellier, Pittville, Charlton Kings, and Leckhampton. The town's Georgian and Victorian heritage means many properties have drainage systems over a century old.

Cheltenham's tree-lined streets are beautiful but create drainage challenges. Root ingress from mature trees is one of the most common issues we deal with in the town.

Stroud District

The Stroud valleys, where five valleys meet at the market town of Stroud, present unique drainage challenges. The steep terrain means gravity drainage systems that can be affected by ground movement, and the area's industrial heritage includes many converted mill buildings with complex drainage.

We cover Stroud town centre, Nailsworth, Dursley, Stonehouse, and the many villages scattered across the valleys including Painswick, Minchinhampton, and Chalford.

Tewkesbury Borough

Tewkesbury, at the confluence of the Rivers Severn and Avon, is famously prone to flooding. This affects drainage systems too, with high water tables and flood events putting strain on infrastructure.

We cover Tewkesbury town, Bishop's Cleeve, Winchcombe, and the surrounding villages. Our engineers understand the specific challenges of drainage in flood-prone areas.

Cotswold District

The Cotswold district covers the eastern part of the county, including the famous honey-stone villages that attract visitors from around the world. We serve Cirencester (the "Capital of the Cotswolds"), Stow-on-the-Wold, Moreton-in-Marsh, Bourton-on-the-Water, Northleach, and Tetbury.

Properties here often have centuries-old drainage, and the area's popularity means many buildings have been converted and extended over the years, creating complex drainage layouts.

Forest of Dean

The Forest of Dean, to the west of the Severn, has a distinct character. Towns like Coleford, Lydney, Cinderford, and Newent serve communities that often rely on private drainage systems rather than mains sewerage.

The area's industrial heritage, including historic mining, affects ground conditions and drainage. Our engineers understand the specific challenges of working in the Forest.

Common drain blockages in Gloucestershire

Understanding what causes drain blockages helps you prevent them. Here are the most common issues we deal with across Gloucestershire:

Fat, oil, and grease blockages

The number one cause of kitchen drain blockages in Gloucestershire homes. When fat goes down your plughole, it might be liquid, but it solidifies as it cools in your pipes. Over time, this builds up into solid masses that completely block your drains.

Gloucestershire's thriving food scene, from Cheltenham's restaurants to the gastro pubs scattered across the Cotswolds, contributes to the problem. Commercial fat deposits in the public sewer network can cause blockages that back up into private drainage systems.

Prevention tip: Never pour cooking fat down the drain. Let it cool and solidify, then scrape it into your food waste bin.

Wet wipes and sanitary products

Despite what the packaging says, most wet wipes don't break down properly in drainage systems. They catch on rough patches inside pipes, accumulate with other debris, and create stubborn blockages that are difficult to shift.

We remove tonnes of wet wipes from Gloucestershire drains every year. Even products labelled "flushable" can cause problems, particularly in older drainage systems.

Prevention tip: Only flush the three Ps: pee, poo, and paper. Everything else goes in the bin.

Tree root ingress

Gloucestershire is a well-treed county, from the ancient Forest of Dean to the mature gardens of Cheltenham's grand villas. Those trees need water, and when their roots detect moisture escaping from drain joints, they grow towards it. Over time, they can penetrate drainage pipes, causing blockages and structural damage.

This is particularly common in Cheltenham's leafy suburbs, the established villages of the Cotswolds, and anywhere with mature trees near drainage runs.

Prevention tip: If you have large trees near your property, consider a CCTV drain survey every few years to catch root intrusion early.

Limestone and mineral buildup

The Cotswolds are famous for their limestone geology, and this affects drainage too. Hard water in the area can cause mineral deposits to build up inside pipes over time, gradually reducing their capacity and eventually contributing to blockages.

This is particularly common in older properties with original clay or cast iron drainage.

Collapsed or damaged pipes

Gloucestershire has properties ranging from brand new to several centuries old. Older properties often have clay or cast iron drainage pipes that deteriorate over time. Ground movement, tree roots, heavy vehicle traffic, and simple age can cause pipes to crack, collapse, or become misaligned.

The county's varied geology, from Cotswold limestone to Severn valley clay, creates different ground conditions that affect drainage systems in different ways.

When a pipe collapses, debris accumulates at the collapse point, creating a blockage. The solution isn't just clearing the blockage but repairing or replacing the damaged section.

Foreign objects

Children's toys, mobile phones, jewellery, excessive toilet paper, and countless other items end up in drains. Sometimes it's accidental, sometimes it's curiosity (parents of toddlers, you know what we mean), and sometimes we never do find out how a full-size action figure got into an outside drain.

Whatever's causing your blockage, we have the equipment and expertise to remove it and get your drains flowing freely again.

Our drain unblocking methods

Different blockages require different approaches. We arrive equipped to deal with whatever we find:

High-pressure water jetting

Our primary tool for most blockages. High-pressure water jetting uses specialised nozzles to blast water at pressures up to 4,000 PSI through your drains. This breaks up blockages, scours the pipe walls clean, and flushes debris through to the main sewer.

Jetting is highly effective against fat and grease buildups, accumulated debris, and light root intrusion. It's also the best way to clean drains preventatively, removing buildup before it becomes a full blockage.

Mechanical drain cleaning

For blockages that won't shift with water alone, we use mechanical cleaning equipment. Rotating cutting heads can break through solid blockages, cut through root masses, and clear compacted debris.

We match the cutting head to the pipe size and blockage type, ensuring effective cleaning without damaging your drainage system.

CCTV drain surveys

When we need to see exactly what's happening inside your drains, we deploy our CCTV survey equipment. Waterproof cameras travel through your drainage system, sending back real-time footage that shows us the blockage location, its cause, and the overall condition of your pipes.

CCTV surveys are essential for diagnosing complex blockages, locating collapsed pipes, and planning repair work. We provide you with the footage and a detailed report of our findings.

Manual rodding

Sometimes the traditional approach is the best one. Manual drain rods are effective for clearing straightforward blockages in accessible drain runs. They're quick to deploy and often all that's needed for simple blockages close to access points.

Drain unblocking for Gloucestershire businesses

Commercial drain blockages can disrupt your operations, drive away customers, and create health and safety issues. We provide rapid commercial drain unblocking services to businesses across Gloucestershire.

Hotels and hospitality

Gloucestershire's tourism industry is a major part of the local economy. Hotels, guest houses, and holiday cottages across the Cotswolds rely on functioning drainage, and a blockage during peak season can be disastrous for both operations and reputation.

From Cheltenham's grand hotels to rural B&Bs in the Forest of Dean, we provide rapid response to keep hospitality businesses running smoothly.

Restaurants and food service

Gloucestershire's food scene has grown significantly, with award-winning restaurants and traditional pubs across the county. Kitchen drains face heavy demands and are prone to fat and grease blockages.

We keep commercial kitchens draining properly, with both emergency callouts and scheduled maintenance to prevent problems before they happen.

Retail and commercial premises

Blocked toilets in retail premises create customer complaints and can force you to close facilities. We respond quickly to commercial blockages across Gloucestershire's shopping centres, high streets, and business parks.

Educational institutions

Gloucestershire is home to the University of Gloucestershire and numerous schools and colleges. These institutions need reliable drainage, and we work with facilities teams across the county to keep educational buildings functioning properly.

Property management

If you manage multiple properties across Gloucestershire, you need a reliable drainage contractor you can call whenever tenants report problems. We work with property managers and letting agents across the county, providing consistent service whether the call is for a flat in Gloucester or a cottage in Bourton-on-the-Water.

Emergency drain unblocking in Gloucestershire

Some blockages can't wait until morning. Sewage backing up through your toilet, drains overflowing into your garden, or water flooding your kitchen floor all require immediate attention.

Our 24/7 emergency service means you're never left waiting with a drainage crisis. Call us any time, day or night, and we'll dispatch an engineer immediately.

What counts as a drainage emergency?

You should call our emergency line if you're experiencing:

• Sewage backing up into your property
• Drains overflowing and flooding outdoor areas
• Complete blockage of your only toilet
• Foul smells from drains inside your property
• Multiple fixtures affected (suggesting a main drain blockage)
• Any drainage issue creating a health hazard

What to do while you wait

If you've called us for an emergency and you're waiting for our engineer to arrive:

1. Stop using water - Don't flush toilets, run taps, or use appliances that drain water. Every bit of water you add makes the problem worse.
2. Protect your property - If water is escaping, move valuable items out of the way. Put down towels or use a wet vacuum if you have one.
3. Ventilate the area - If there are foul smells, open windows and doors to improve ventilation. Avoid spending extended time in affected areas.
4. Don't try chemical drain cleaners - These are rarely effective on serious blockages and can be dangerous for our engineers to work around.
5. Locate your outside drain - If you can safely identify and access your outside drain, this helps our engineer get started faster when they arrive.

Preventing drain blockages

The best blockage is one that never happens. Here's how to keep your Gloucestershire property's drains flowing freely:

In the kitchen

• Never pour fat or oil down the drain - Let it cool and dispose of it in your food waste bin
• Scrape plates thoroughly - Food debris should go in the bin, not down the sink
• Use sink strainers - Catch food particles before they enter your drains
• Run hot water after washing up - This helps flush grease through the system
• Clean your waste disposal regularly - If you have one, keep it clean and avoid overloading it

In the bathroom

• Only flush the three Ps - Pee, poo, and (toilet) paper. Nothing else.
• Use drain covers - Catch hair before it enters your drains
• Clean pop-up stoppers regularly - Hair and soap scum accumulate on these
• Avoid excessive bath products - Some can contribute to buildup in pipes

Outside

• Keep drain covers clear - Remove leaves, debris, and any obstructions
• Don't plant trees too close to drains - Roots can travel considerable distances to find water
• Know where your drains are - Don't build over them or block access
• Consider periodic maintenance - Annual jetting can prevent buildup becoming blockages

For listed and historic properties

• Understand your drainage layout - Older properties often have complex, modified systems
• Consider regular inspections - Catch deterioration before it causes problems
• Work with specialists - Historic drainage often needs careful handling
• Keep records - Document any work done for future reference

• Full property survey with report: From £245
• Commercial surveys: Priced based on system size

Drain repairs in Gloucestershire

When clearing a blockage isn't enough, we provide full drain repair services across Gloucestershire. Our repair capabilities include:

Patch lining

For localised damage like cracks, small holes, or joint failures, patch lining provides a repair without excavation. We install a resin-impregnated patch that bonds to the inside of the pipe, sealing the damage and restoring structural integrity.

Drain relining

When a longer section of pipe is damaged, drain relining (also called cured-in-place pipe or CIPP) creates a new pipe within the old one. A flexible liner saturated with resin is pulled through the damaged pipe, inflated against the pipe walls, and cured in place. The result is a seamless, jointless new pipe without the need for excavation.

This is particularly valuable in the Cotswolds, where excavation through historic courtyards or gardens can be disruptive and expensive.

Excavation and replacement

Some damage requires traditional excavation and pipe replacement. If a pipe has completely collapsed, been severely displaced, or is beyond repair, we'll excavate, remove the damaged section, and install new pipework.

We always explore no-dig options first, but when excavation is necessary, we do it properly. We handle everything from small domestic repairs to major drain reconstruction projects.

Why Gloucestershire properties develop drainage problems

Understanding why drains block helps you prevent problems. Here's what makes Gloucestershire properties susceptible to drainage issues:

Age and variety of housing stock

Gloucestershire's housing ranges from medieval Cotswold cottages to brand-new developments. This means drainage systems of every age and type, each with their own vulnerabilities:

• Historic Cotswold properties often have drainage that's been modified many times over centuries, with complex layouts that can be difficult to trace.
• Georgian and Victorian properties, common in Cheltenham and Gloucester, often have clay pipes with lime mortar joints that deteriorate over time.
• Post-war properties may have concrete or pitch fibre pipes. Pitch fibre in particular is prone to deformation and collapse.
• Modern properties typically have robust uPVC systems, but poor installation can still cause problems.

Geological factors

Gloucestershire's geology varies significantly across the county:

• Cotswold limestone creates hard water that can cause mineral buildup in pipes
• Severn valley clay can cause ground movement affecting pipe alignment
• Forest of Dean has varied geology including areas affected by historic mining

Flood risk areas

Parts of Gloucestershire, particularly around Tewkesbury and the Severn valley, are prone to flooding. Flood events put stress on drainage systems, and high water tables can affect drainage performance year-round.

Tourism and seasonal pressure

The Cotswolds' popularity as a tourist destination puts seasonal pressure on drainage systems, particularly in popular villages. Holiday lets and hospitality businesses see intensive use during peak periods.

Rural drainage challenges

Much of Gloucestershire is rural, with properties relying on private drainage systems, septic tanks, and long runs of pipework. These systems require more maintenance than urban drains connected to mains sewerage.

Frequently asked questions

How quickly can you get to me?

For most areas of Gloucestershire, we can reach you within 60 minutes. Gloucester, Cheltenham, and Stroud typically see response times of 30-45 minutes. More rural areas of the Cotswolds and Forest of Dean may take slightly longer, up to 90 minutes in some locations.

Do you charge a callout fee?

No. We don't charge for turning up. You only pay for the work we actually do.

Can you unblock drains at night?

Yes. We operate a genuine 24/7 service. Whether you call at 2pm or 2am, we'll have an engineer on the way.

What if you can't clear the blockage?

It's rare, but occasionally we encounter blockages that can't be cleared (usually due to collapsed pipes). In these cases, you don't pay for unsuccessful work. We'll explain what we've found, provide a CCTV survey of the problem, and quote for the repair work needed.

Do I need to be home?

For inside blockages, yes. For outside drains that are accessible without entering your property, we can sometimes attend while you're out, though we prefer to show you what we've found and explain the work.

How do I know if the blockage is my responsibility?

Generally, drains within your property boundary are your responsibility. The public sewer (usually under the road or shared between multiple properties) is the water company's responsibility. In Gloucestershire, this is Severn Trent Water. If you're unsure, we can help you determine where the problem lies.

Can you help with drains that smell but aren't blocked?

Yes. Drain smells often indicate partial blockages, dried-out traps, or ventilation problems. We can diagnose and resolve most smell issues.

Do you do CCTV surveys without unblocking work?

Absolutely. We provide standalone CCTV surveys for homebuyers, property sellers, landlords, and anyone who wants to know the condition of their drains.

What areas of Gloucestershire do you cover?

All of it. We serve every part of Gloucestershire, from Tewkesbury in the north to Dursley in the south, from the Forest of Dean in the west to Moreton-in-Marsh in the east, and everywhere in between.

Are you insured?

Yes. We carry full public liability insurance and employer's liability insurance. We're happy to provide certificates on request.

Do you offer guarantees?

We provide a 30-day guarantee on all unblocking work. If the same blockage returns within 30 days, we'll clear it again at no charge.

Can you deal with shared drains?

Yes. Shared drains serving multiple properties can be complicated, but we deal with them regularly. We can help you identify who's responsible for what and coordinate with neighbours if needed.

Do you work with listed buildings?

Yes. We understand the sensitivities of working on listed properties and can provide appropriate solutions that respect historic fabric while solving drainage problems.
