When winter arrives in Salisbury, colder temperatures and increased rainfall can place extra pressure on household drainage systems. For many local homeowners, blocked drains and surface flooding only become noticeable after damage has already occurred. The good news is that taking a few preventative steps now can help protect your home, avoid costly repairs, and ensure your drains keep flowing freely throughout the season.
This guide provides a clear, practical winter drain maintenance checklist, designed specifically for Salisbury properties — including older homes, rural cottages, and newer estates experiencing seasonal drainage strain.
Why Winter Causes More Drain Problems
During winter, the combination of heavy rain, falling leaves, soil movement, and freezing water significantly increases the risk of blockages. Common issues include:
- Leaf buildup restricting flow in gutters and drains
- Tree root intrusion into older clay and pitch fibre pipes
- Collapsed drain sections weakened by frost and heavy ground pressure
- Grease and fat deposits from holiday cooking solidifying in pipes
- Soakaways struggling to disperse water in saturated ground
Being proactive now reduces emergency callouts later — often saving hundreds of pounds in repairs.
🧰 Your Winter Drain Maintenance Checklist
1. Clear Gutters and Downpipes
Blocked gutters cause water to overflow and seep into walls or foundations. Ensure:
- Leaves and moss are removed
- Downpipes flow freely
- Water is not pooling around the property
This is particularly important for listed properties and period homes in Salisbury, where drainage design is often more sensitive.
2. Inspect External Drains and Gully Pots
Many blockages start at gully drains where kitchen and roof water enters the system.
Check for:
- Silt, sludge, or standing water
- Food fats and grease buildup
- Cracked or misaligned gully traps
If water drains slowly, action is required.
3. Remove Fat, Oil, and Grease Blockages
Winter and holiday cooking may lead to FOG buildup inside pipes.
Avoid:
- Pouring oil down the sink
- Rinsing greasy pans directly
Instead:
- Wipe pans with tissue before washing
- Use a drain-friendly enzyme treatment
Even better: book a periodic drain flush or jetting service.
4. Look for Warning Signs of Root Intrusion
Garden trees continue to grow underground in winter.
Roots seek water — and drains are a perfect source.
Signs include:
- Frequent slow draining sinks
- Gurgling sounds
- Recurring blockages
- Sewage smells indoors or outdoors
Root ingress can quickly become an emergency if ignored.
5. Check Your Soakaway’s Performance
Salisbury’s rural villages and older homes often rely on soakaway systems.
Check for:
- Standing surface water after rainfall
- Water backing up into drains
- Waterlogged lawns (especially clay-heavy areas)
If your soakaway is struggling now, winter will worsen it.
6. Book a CCTV Drain Survey Before Frost
A CCTV drain survey detects hidden cracks, collapsed sections, blockages, and root intrusions.
It prevents emergencies by identifying problems early.
👉 If your property is over 20 years old, this is highly recommended.
📍 Why This Matters for Salisbury
Salisbury and surrounding areas such as Wilton, Amesbury, Downton, and Fordingbridge experience:
- High water tables
- Clay-heavy soils
- High rainfall across November–March
This means drains face more stress compared to other regions.
Regular winter checks significantly reduce risk.

Winter Maintenance FAQs
How can I tell if my drain is blocked?
Slow draining sinks, gurgling pipes, or sewage smells are common signs. If more than one drain is affected, the issue is likely in the main system.
Do I really need a CCTV drain survey?
Yes — especially for older properties, or if you have repeated blockages. It identifies issues before they become emergencies.
What if my soakaway is failing?
We assess whether it can be rejuvenated or whether a modern replacement is required, based on ground conditions and drainage capacity.
Are winter drain repairs more expensive?
Not necessarily. Emergency callouts are what drive costs up. Preventative maintenance is far more affordable.
