Signs Your Gutters Need Cleaning
Your gutters play a big role in protecting your home from water damage but it’s easy to forget about them. If they become blocked or start overflowing, you could end up with damp walls, stained brickwork, or even problems with your foundations.
So how do you know when it’s time to clean your gutters? Here are the most common signs to look out for.
🌧️ 1. Water Overflowing When It Rains
The most obvious sign your gutters need cleaning is water spilling over the edge during rainfall. Instead of flowing through the system and down the pipe, it backs up and pours out in the wrong place.
This can cause:
Damp patches on your walls
Water pooling near your home’s foundation
Damage to your roof or fascia boards

2. Sagging Gutters
Blocked gutters often become too heavy. Leaves, moss, and trapped water can weigh them down, causing the gutters to sag or pull away from the wall.
Sagging gutters are not only unsightly, they also stop water from draining properly. Over time, this can lead to bigger problems, including rotting the fascia boards and leaks.
If you’re seeing these issues, it’s probably time to book a professional gutter cleaning service to avoid damage and damp.
🌿 3. Plants or Moss Growing in the Gutter
If you can see weeds, moss, or even grass growing in your gutters, they’re long overdue for a clean. Seeds from nearby trees can settle in the debris and take root, turning your gutters into mini gardens.
This is a clear sign that water isn’t flowing the way it should.
💡 Annual maintenance can prevent this from happening
🧱 4. Stains or Peeling Paint on Exterior Walls
When gutters overflow, water often runs down your exterior walls. Over time, this leaves behind green streaks, dirty marks, or peeling paint.
You might also notice damp patches forming near the top of the wall. Left untreated or all the way down the wall which has moss growing where the bricks are, this could affect the inside of your property too.
5. Damp or Musty Smells Indoors
Sometimes the signs of blocked gutters show up inside your home. Water from overflowing gutters can seep into the roofline or walls, especially around the fascia and soffits.
This can lead to:
Musty smells in upstairs rooms
Mould growth on ceilings or walls
Bubbling or peeling paint indoors

👂 6. Dripping or Gurgling Sounds
If you hear strange dripping or gurgling noises from your guttering even when the rain has stopped, it could mean water is struggling to get through a blockage.
This is a subtle but early warning sign.
✅ Final Check: Time to Clean?
Here’s a quick checklist:
✅ Water overflowing?
✅ Gutters sagging?
✅ Plants or moss in the gutter?
✅ Stains or peeling paint on the wall?
✅ Damp smells or mould indoors?

If you’ve ticked one or more, your gutters need attention. Regular cleaning, just once a year for most homes can prevent bigger issues and save you money in the long run.
