Why Plumbing Renovation In Streatham Requires A Different Approach
Many homes in Streatham date back to the Victorian or Edwardian era. While the architecture is timeless, the plumbing systems often aren’t. Old galvanised steel pipes, lead supply lines, and poorly adapted upgrades are common.
A successful plumbing renovation in Streatham starts with understanding what’s already there and what needs replacing, upgrading, or re-routing to meet modern standards.
Assess The Existing Pipework Before You Start
Before any cosmetic work begins, we always recommend a complete plumbing inspection.
Common Issues In Older Streatham Homes
- Corroded metal pipes are restricting the flow
- Hidden leaks beneath floors
- Mixed pipe materials from past alterations
- Poor water pressure due to ageing supply lines
Catching these early prevents significant disruption later. During renovations, access is easier making it the ideal time to upgrade old pipework rather than patch it.
This approach aligns with our plumbing repairs and general maintenance services, which often support renovation projects across South London.
Plan For Modern Water Pressure And Demand
Older plumbing systems weren’t designed for today’s bathrooms, power showers, or multiple appliances operating simultaneously.
If you’re adding:
- An extra bathroom
- A rainfall shower
- A dishwasher or washing machine
You’ll likely need to address water pressure. During a plumbing renovation in Streatham, this may involve upgrading pipe sizes, installing pressure-boosting solutions, or improving distribution throughout the home.
This is where our water pressure services are often built directly into renovation work, rather than treated as an afterthought.
Replace Outdated Hot Water Systems
Many older Streatham properties still rely on legacy hot-water systems that struggle to meet modern usage.
Options Worth Considering
- Upgrading to an unvented hot water cylinder
- Replacing old immersion heaters
- Installing secondary circulation for faster hot water delivery
Modern systems are more efficient, safer, and better suited to renovated homes. Planning this during your plumbing renovation prevents the need to reopen walls later.
Our team regularly supports renovations by upgrading hot water systems and installing unvented hot water cylinders, ensuring systems are future-ready.
Don’t Overlook Drainage And Waste Pipes
Drainage is often ignored until there’s a problem. In older homes, waste pipes may be undersized, poorly vented, or damaged by decades of use.
During a plumbing renovation in Streatham, it’s smart to:
- Check the fall and alignment of waste pipes
- Upgrade old cast-iron or clay sections
- Ensure new bathrooms are properly vented
This reduces the risk of blockages, odours, and long-term maintenance issues.
Be Careful With Saniflo And Macerator Systems
Basement bathrooms and loft conversions sometimes rely on macerator systems. While useful, they must be installed correctly and maintained properly.
In renovation projects, we often review:
- Whether a Saniflo is necessary
- Pipe routing and discharge points
- Noise and vibration control
If you’re considering this option, professional guidance is essential. Our experience with Saniflo repairs and installations helps homeowners avoid common mistakes.
Update Stopcocks, Valves, And Isolation Points
One minor but crucial renovation tip: make sure you can isolate water easily.
Older homes often have:
- Seized stopcocks
- Hidden isolation valves
- No individual shut-offs for appliances
During a plumbing renovation in Streatham, upgrading these components will make future maintenance far simpler and reduce the risk of emergencies.

Renovating an older home isn’t just about fitting new pipes; it’s about respecting the structure while upgrading safely.

-
Can old pipework affect water pressure?
Yes. Narrowed or corroded pipes are a common cause of low pressure in older Streatham homes.
-
Is planning permission needed for plumbing changes?
Usually not for internal plumbing, but listed buildings or significant alterations may require approval; always check first.

When is the best time to upgrade plumbing?
During renovation, when floors and walls are already open. It’s cheaper and far less disruptive.
