The sunshine might be welcome, but hot weather can cause hidden problems for your drainage system — especially in older homes.
There tends to be a spike in callouts during the hotter weather regarding bad smells and drain issues, and here’s why:
🔥 Why hot weather causes drain issues:
Dried-out pipe joints: Extreme heat can cause expansion, leading to gaps or minor leaks.
Strong smells: Warm temperatures and hot weather accelerate the breakdown of waste, making odours worse.
Tree roots: Roots search for moisture and can crack into your pipes during dry spells.
✅ What you can do to help your drains:
Flush infrequently used drains (like guest bathrooms)
Don’t pour cooking fats or oils down the sink – they harden fast in the heat
Book a drain check if you notice bad smells, slow draining, or gurgling noises
Our engineers are working across Kent, South London and other surrounding areas to help homeowners and businesses keep things flowing smoothly this summer.
