Every building, whether a home or commercial property, relies on gutters to safely move rainwater away from the roof and foundation. When those gutters get clogged with leaves, moss, or dirt, the entire system stops working properly. The result? Water damage, damp walls, and costly repairs that could have been avoided.
That’s why professional gutter cleaning is so important. But many people still ask: what does gutter cleaning include? In this article, we’ll go through the process step by step so you know exactly what to expect and why it matters for the long-term health of your property.
Why Gutter Cleaning Matters
Gutters are designed to channel rainwater away from walls, windows, and foundations. When they’re blocked, water spills over the sides, seeps into walls, and can even cause cracks in the foundation. Inside the home, this may lead to dampness, mold growth, or peeling paint.
Regular gutter cleaning prevents these issues and extends the life of your guttering system. It’s not just about appearances; it’s about protecting your property from expensive water damage.
Step 1: Inspection of Gutters and Downpipes
The first step in any professional service is a detailed inspection. Before cleaning begins, the technician checks the condition of the gutters and downpipes.
- Looking for sagging sections or broken brackets
- Identifying cracks, rust, or holes that may cause leaks
- Checking where water is likely to pool or overflow
This initial step ensures that any issues are spotted early and addressed before they become bigger problems.
Step 2: Removing Leaves, Moss, and Debris
Over time, gutters collect a surprising amount of material. Autumn leaves, spring blossoms, roof moss, bird nests, and even rubbish carried by the wind can clog the system.
Professionals use safe methods and the right tools to remove this build-up. Depending on the property, they may use ladders, scoops, or high-reach vacuums to clear everything out. The goal is to restore full flow without damaging the gutters.

Step 3: Flushing the Gutters
After the main debris is removed, gutters are flushed with water. This step washes away fine dirt, grit, and moss fragments that are too small to pick out by hand.
Flushing also doubles as a test. By watching the flow of water, technicians can see if there are hidden blockages or leaks. It’s an important part of making sure the system is truly clear from end to end.
Step 4: Checking for Leaks and Repairs
While flushing, the team looks for signs of leaks. Water escaping from joints, dripping from cracks, or rust spots are all common issues.
Small problems, such as loose seals, can often be fixed during the visit. Larger damage may require replacement parts or more detailed repair work. Either way, spotting these issues during cleaning prevents surprises later when heavy rain arrives.
Step 5: Clearing and Testing the Downpipes
Downpipes are just as important as gutters. They carry rainwater down to the drains or soakaway system. If they’re blocked, water has nowhere to go and will overflow from the roofline.
Technicians run water through the downpipes to make sure everything is flowing as it should. If a blockage is found, they may use pressure flushing or rods to clear it. This step ensures the system works from top to bottom.
Step 6: Tidying Up After the Job
Professional gutter cleaning should always leave your property tidy. Once the gutters and downpipes are clear, the team removes any debris that has fallen on the roof, paths, or garden.
Collected waste is bagged and taken away for disposal. This means homeowners don’t have to deal with piles of leaves or moss left behind after the job is done.

How Often Should Gutters Be Cleaned?
The ideal frequency depends on your location and surroundings. In London and Surrey, where many properties are close to trees, twice a year is usually recommended.
- Spring cleaning removes debris that built up over winter.
- Autumn cleaning clears falling leaves before winter storms.
If your property is surrounded by trees or prone to moss growth, you may need more frequent visits. Regular maintenance helps prevent sudden blockages during heavy rain.
DIY or Professional Cleaning – What’s Best?
Many homeowners consider cleaning their gutters themselves. While this can work for small, easy-to-reach properties, there are important differences between DIY and professional cleaning.
DIY Gutter Cleaning Limitations:
- Hard to reach high roofs safely
- Lack of proper equipment for flushing or testing
- Easy to miss small cracks or early signs of damage
Professional Gutter Cleaning Advantages:
- Safe working at height with ladders and safety gear
- Thorough cleaning of both gutters and downpipes
- Ability to spot and fix minor problems immediately
- Faster and more efficient results
Hiring professionals saves time and reduces risks, especially for larger or taller properties.
Extra Services Often Included
Alongside cleaning, many companies provide additional services to keep gutter systems in good condition. These may include:
- Resealing joints and minor repairs
- Installing gutter guards to reduce blockages
- Emergency call-outs during heavy rain
- Maintenance plans for year-round protection
These extras provide long-term value and reduce the chances of sudden, costly repairs.
