Drainage & Blockages
Root Ingress Investigation (Domestic)
Tree root ingress can crush, crack or choke pipework, leading to slow draining, recurring blockages, odours and even overflows. A root ingress investigation identifies where the roots are getting in, clears the obstruction using non-excavation methods where possible, and confirms the drain is flowing properly again.
More information
What a root ingress investigation covers
This service is designed to quickly pinpoint and resolve root-related drainage issues, with clear next steps if repairs are needed.
- Assess symptoms and likely affected runs (internal and external waste where accessible)
- Locate the blockage and identify whether roots are the cause
- Clear the obstruction using appropriate non-excavation methods
- Check flow has been restored and the blockage has not immediately re-formed
- Explain findings in plain English and advise on prevention or repair options
When this service is the right fit
Book a root ingress investigation if you are dealing with:
- Slow draining sinks, baths, showers or WCs that keeps coming back
- Gurgling, bad smells, or wastewater backing up
- Outside gullies overflowing during normal use
- A known nearby tree or shrubs close to the drainage line
- A recent blockage clearance that did not last
What happens during the visit
The aim is to find the cause, clear it safely, and confirm the drain is working.
- We ask a few questions about the symptoms, frequency and any recent works
- We inspect access points and isolate the most likely section of pipework
- We clear the blockage using the least disruptive method suitable for the pipe and blockage type
- If helpful, we may recommend further inspection (for example CCTV) to confirm pipe condition and entry points
After the investigation
Root ingress often indicates an underlying defect, so the next step depends on what we find.
- If flow is restored, we outline what to watch for and how to reduce repeat issues
- If roots have entered through a crack or displaced joint, we explain repair options and urgency
- Where appropriate, we can recommend longer-term fixes to reduce recurrence, rather than repeated clear-outs
Frequently Asked Questions
How do I know if roots are causing my drain blockage?
Recurring blockages, slow drainage and bad odours can all point to root ingress, especially if there are trees or shrubs nearby. The investigation confirms whether roots are present and where they are entering.
Is this service non-excavation?
The investigation and clearance are carried out using non-excavation methods wherever possible. If we find the pipe is damaged, we will explain any repair options before any digging is considered.
Will clearing the roots stop the problem coming back?
Clearing restores flow, but roots can return if there is a crack, open joint or damaged section of pipe. If we suspect an entry point, we will advise on repair or protection to reduce repeat blockages.
How long does a root ingress investigation take?
Timing depends on access, the severity of the blockage and how far along the line it is. Most domestic investigations are completed in a single visit, but complex issues may need further inspection.
What should I do before you arrive?
If possible, avoid using affected fixtures to reduce the risk of overflow. Clear access to any inspection covers or areas around the suspected drain run, and note when the issue started and how often it occurs.
