7 Signs Your Gutters Need Cleaning

Your gutters need cleaning if water spills over the edge in rain, the run sags, plants grow in it or stains appear on the wall below. You can check most of these signs from the ground, because they show from outside. A few minutes during a downpour tells you more than any ladder inspection.

Below are seven signs, from the easiest to spot to the most serious. If you see more than one, book a clean soon. Early action keeps repairs small, since damage spreads.

1. Water pours over the edge in rain

This is the clearest sign. In heavy rain, a clear gutter carries water to the downpipe. However, a blocked one fills and spills over the front.

Stand outside and watch during a storm. You may see a curtain of water falling from one section. That spot is usually where the blockage sits, because water spills at the low point.

2. Plants and moss grow in the channel

Leaves and soil break down into a thin compost. Seeds then take root, so you may see grass, weeds or even small saplings. Moss is equally common, although it is easier to miss.

Plants are a sign that debris has been there for months. Therefore, treat them as urgent. Their roots can push into joints and lift the gutter. Our guide to moss and leaves in gutters explains how to deal with them.

3. The gutter sags or pulls away

A full gutter is heavy, since wet debris weighs far more than it looks. Brackets bend and the run drops in the middle. Water then pools in the dip, which adds more weight.

If a section leans away from the fascia, the fixings may have failed. That needs a repair, because a clean cannot refit a bracket. Read our comparison of gutter repair and replacement to see what to expect.

4. Stains and streaks on the wall

Look at the brickwork beneath the gutter. Green or black streaks mean water has run down the wall again and again, while dark patches near the eaves point the same way. Dark patches near the eaves point the same way.

Damp is the real worry here, because it spreads inside. Blocked gutters and defective downpipes are a common cause of water getting into walls. Our post on what happens if you do not clean gutters follows the damage step by step.

5. Dripping or pooling in the wrong places

Water should leave the system at the downpipe. If it drips from the middle of a run, a joint or the channel itself is leaking. Debris often sits directly above these leaks.

Check the ground as well. For instance, pools at the foot of a wall suggest water is not reaching the drain. In that case, the downpipe may be blocked too.

6. Birds, wasps or small animals nest in the gutter

Gutters full of leaf litter make a warm, sheltered home. For example, birds often nest in the corners of a run. A nest adds to the blockage and can hold water.

Take care here, since nesting season matters. If you find a nest in use, wait until the young have gone before clearing it. Plan your clean for later in the season.

7. It has been a year or more

Sometimes the sign is the calendar. Most homes need a clean once or twice a year, because debris builds steadily. Our guide on how often you should clean your gutters sets out the rhythm. If you cannot remember the last time, it is probably overdue.

Heavy leaf fall can bring the date forward, especially if you have trees close to the house. Check the gutters after autumn storms, since they may look fine one month and fail the next.

What to do when you spot a sign

Start with the gutters, since clearing the debris fixes most overflow problems. You can do it yourself if you work safely, although our guide to DIY and professional gutter cleaning shows the risks of ladders.

If the gutter still leaks after a clean, you may need a repair. Look at our gutter cleaning service for the first step. Our gutter repair service covers leaks and loose fixings.

Examples from local towns

Homes with mature trees show these signs earlier, because they gather more debris. Our teams doing gutter cleaning in Kenilworth often see leaf-packed runs by November. Our Rugby gutter cleaners see the same pattern on larger gardens.

Wherever you live, the signs are the same. Act early because small fixes cost less. For guide prices, see our pricing page.

How urgent is each sign?

Not every sign needs a call today. Treat water pouring over the edge, a sagging run or damp indoors as urgent. These can cause damage within weeks, so act soon.

Plants, moss and light staining are warnings. They tell you the gutter is overdue, although they rarely cause harm in a few days. Book a clean before the next wet season, and read our guide to preparing gutters for winter to plan the timing.

If you are unsure, a short check helps. A professional can tell you whether the gutter needs a clean, a repair or nothing at all. That advice is free with our quote, so you lose nothing by asking. We would rather tell you the gutters are fine than sell you a clean you do not need, because trust brings repeat customers.

Keep a note of what you see and when. Photos taken from the ground show change over time, for example a stain that grows after each storm. That record helps us give a more accurate quote, since we can see how fast the problem develops.

Book a clean before the next storm

You do not need to wait for the damage to show, because a routine clean removes the debris before it causes trouble. We confirm a fixed price before any work starts.
