Gutter cleaning in Windsor, Berkshire and South West London, with moss, leaves and silt cleared by hand by roofers who check the roof while they are up there. Book a free inspection and you get photos of what we find and a fixed written quote.
Your gutters collect every drop that runs off the roof. When they are blocked, that water has to go somewhere, and it goes over the front edge and down the wall. That is how a twenty-minute clear-out turns into damp patches inside, rotten fascia boards, stained brickwork and water pooling against the foundations.
Homes near trees fill fastest. Leaves in autumn, pine needles all year round, moss washing down off the tiles and silt from the roof all build up in the gutter and set into a mat that blocks the outlets.
The signs your gutters need clearing:
Clearing the gutter is the easy part. Making sure the water then leaves the building is what you are paying for.
Moss, leaves and silt scooped out by hand, not blasted down the downpipes to block them further down.
Outlets and swan necks cleared so water drops straight into the downpipe.
Each downpipe checked through to the gully at ground level, so the water is actually leaving the building.
Joints, brackets, falls and the roof edge checked, with photos of any faults so you know exactly what you have.
A gutter vac on a pole clears the gutter. It does not see the slipped tile above it, the moss holding water against the bottom courses, the cracked mortar on the verge or the fascia board going soft behind the bracket. We do, because we are roofers and we are looking at the whole roof edge from the ladder.
So you get more than a clean gutter. If a joint is leaking, a bracket has snapped or a run has lost its fall so water sits in the middle, we photograph it and tell you. If moss on the roof is what keeps filling the gutters, we tell you that too. Small faults found at the gutter line are the cheapest roof repairs there are.
And if your gutters are cracked, brittle or undersized for the roof, clearing them again will not fix the overflow. That is a repair or a new run, covered on our gutter repair and replacement page.
Once a year after the leaves have dropped is right for most homes, before the winter rain arrives. Homes under trees, and especially under pines, need it more often, because needles fall all year and pack down hard.
Gutter clearing is priced on the size of the house, the length of the gutter runs and the access, and you get a fixed written price before we start. Any repairs we find are priced separately and only done with your go-ahead. Our roof repair cost guide puts a fascia or gutter repair at £100 to £350 for 2026.
If you are booking other roof work, clearing the gutters at the same time costs very little extra because the access is already there. On our Fleet re-roof, a house surrounded by mature pines, the gutters and drive were left clean at handover as part of the job.
This Fleet house sits among mature Scots pines and birch. With the tiles off, years of pine needles and debris had packed down into the eaves, where water sits longest. The roof was rebuilt and the site, gutters and drive were left clean at handover.
Tell us about the house and any overflowing you have seen, and we will give you a fixed written price for clearing the gutters and checking the downpipes. Prefer to talk first? Call us any time.
