Some drainage problems can't be fixed with clearing or cleaning. When drains are collapsed, severely damaged, or beyond economical repair, replacement becomes necessary. While it's not what any property owner wants to hear, modern drain replacement techniques are far less disruptive than you might imagine.
At Plumbers 365, we specialise in drain replacement across Bournemouth using the latest methods to minimise disruption to your property. Whether you need a complete drainage system replacement or just a section of damaged pipe replaced, we provide expert solutions with clear pricing and professional workmanship.
When drainage pipes collapse completely, they create a blockage that can't be cleared with jetting or rodding. Collapse is common in:
Older drainage materials have limited lifespans:
Small cracks can sometimes be repaired, but extensive cracking means the pipe structure is compromised. Continued use will lead to leaks, contamination, and eventual collapse.
Tree and shrub roots that have extensively infiltrated drainage pipes can sometimes be cut back, but when they've caused structural damage, replacement is often the only permanent solution.
If drains are leaking sewage into surrounding soil despite repairs, replacement ensures your property is safe and sanitary.
When you're constantly dealing with blockages caused by structural problems rather than user error, replacement provides a permanent solution.
Sometimes building regulations require drain replacement or re-routing when you're extending your property or undertaking major renovations.
Sections of drain that have shifted and created misaligned joints where waste accumulates often need replacing for effective long-term drainage.

For minor blockages, you might be able to clear them yourself using a plunger. Here's how to try:
The conventional method involves:
For some situations, drain lining offers an alternative to excavation:
We'll assess whether lining is suitable for your situation or if replacement is necessary.
Often, only sections of your drainage system are damaged. We can replace just the affected areas rather than the entire system, saving costs and minimising disruption.
We start with a comprehensive CCTV drain survey (if you haven't had one recently) to identify exactly what's damaged, where it's located, and the extent of replacement needed.
Our experienced team carefully excavates to expose damaged drains, minimising disruption to surrounding areas. We use appropriate machinery for the scale of work, from small excavators for garden access to hand digging where necessary.
We provide a clear, fixed-price quote covering:
Before work begins, we protect your property:
Old damaged pipes are removed and properly disposed of. New drainage pipes (typically high-quality PVC meeting current building regulations) are precisely installed with correct gradients for effective drainage.
New drains are connected to your existing system and thoroughly tested. We run water through the system and conduct pressure tests to ensure perfect function.
We handle any necessary permissions or building control notifications. We'll also arrange for you to be present during key stages if you wish.
Trenches are backfilled with appropriate materials, properly compacted to prevent future subsidence. We then reinstate surfaces:
We conduct a final CCTV survey of the replaced section to verify everything is installed correctly and functioning perfectly.

Bournemouth's beautiful Victorian and Edwardian homes often have original clay drainage systems that are over 100 years old. While remarkably durable, these eventually reach the end of their serviceable life. We specialise in sympathetic drainage replacement for period properties, working carefully to preserve garden features and original landscaping.
Homes built in the 1950s-1970s often have pitch fibre drains that are now deteriorating. We've replaced hundreds of pitch fibre drainage systems across Bournemouth, upgrading them to modern PVC that will last for decades.
Even newer homes occasionally need drain replacement due to poor original installation, ground movement, or accidental damage during building work.
Restaurants, shops, and business premises in Bournemouth's town center and seafront areas can't afford prolonged drainage disruption. We plan commercial drain replacement to minimise business interruption, often working outside business hours.
Bournemouth's coastal location can subject drainage systems to ground movement and high water tables. We account for local conditions when designing replacement drainage systems.
For minor blockages, you might be able to clear them yourself using a plunger. Here's how to try:
Pricing varies significantly based on several factors:
Typical Cost Ranges:
Prices are indicative as the cost depends on:
Remember that drain replacement is an investment in your property. Properly installed modern drainage systems last 50+ years and can add value to your home.
We understand that having drains replaced is disruptive. Here's how we minimise the impact:
We plan work carefully and provide realistic timeframes. Most sectional drain replacements complete in 2-4 days, including reinstatement.
We keep you informed every step of the way, explaining what's happening and what to expect next.
We protect your property with covers, barriers, and careful working practices.
If needed, we can arrange temporary drainage during replacement work so your toilets and sinks remain usable.
We maintain a clean, safe work area and remove waste daily rather than allowing accumulation.
We take pride in leaving your property looking as good as (or better than) before, with professional surface reinstatement matching existing materials.
For commercial properties or situations where access is limited, we can work evenings or weekends to minimise disruption.
For some pipe conditions, no-dig lining creates a new pipe within the old one without excavation. We'll assess whether this is viable for your drains.
Small localised damage might be repairable with patch lining or point repairs rather than replacing entire sections.
Often only sections of your drainage system need replacing. We replace exactly what's necessary, not the entire system.
We'll always recommend the most cost-effective solution for your specific situation, explaining options clearly so you can make informed decisions.

No, when performed by experienced professionals. Our engineers know how to rod drains effectively without causing damage. We adjust our technique based on your pipe material and condition.
No, we only excavate where necessary to access damaged drains. Modern techniques and equipment allow us to minimise excavation. We'll show you exactly what areas will be affected before work begins.
Usually yes, though there may be periods when facilities can't be used while we're making connections. For longer projects, we can arrange temporary drainage solutions. We'll discuss this during planning.
If drains run beneath hard surfaces, we'll carefully excavate and then professionally reinstate the surface using matching materials. While we can't guarantee exact matching for weathered patios or driveways, we get as close as possible.
Yes, we manage all necessary building control notifications and inspections as part of our service.
We typically install PVC drainage pipes which are durable, long-lasting, and meet current building regulations. For specific situations, we might recommend other appropriate materials.
