Sign 1: Water Overflowing From the Sides During Rain
When it rains, water should run down the inside of the gutter and away through the downpipe. If water is spilling over the sides and running down the walls of your home, the gutter is blocked. Leaves, moss, sludge, or a combination of all three is backing water up. This water runs down your brickwork and soaks into the cavity walls. If ignored, this causes damp inside your home that spreads quickly.
Sign 2: Damp Patches on Internal Walls
You've noticed a dark patch inside your bedroom or living room — usually near the top of the wall, or in a corner where the gutter runs. That's water that's entered through the roof or down from blocked gutters, migrating through the brickwork and coming out inside. Once damp is visible inside, it's been present for weeks. Act immediately.
Sign 3: Paint Peeling on Fascia Boards
Your fascia boards are the boards that run along the edge of your roof where the gutter attaches. If the paint is bubbling, peeling, or the wood looks soft or discoloured, water is running down behind the gutter — usually because the gutter is overflowing. The wood soaks up water, swells, and the paint cracks. A replacement fascia board costs hundreds of pounds. A gutter clean costs a fraction of that.
Sign 4: Plants Growing From Inside Your Gutters
If you can see moss, weeds, or even small plants growing inside your gutters, the gutter hasn't been cleaned in years. This means the gutter is clogged with organic matter — decomposed leaves, bird droppings, moss — with enough depth for plants to root. These plants block drainage completely. We use a SkyVac ground-level vacuum system to clear these completely, with no ladders required.
Sign 5: Rust, Staining, or Streaks Down the Brickwork
Black or rust-coloured streaks running down your external walls mean water is pouring out of the gutters and carrying sludge with it. In Chelmsford and Basildon where many homes have render, this staining looks terrible and indicates water damage is happening behind the scenes. The acidic run-off from decomposing organic matter also accelerates weathering of the mortar between bricks. Once pointing fails, water gets into the cavity.
Sign 6: Birds Nesting in Your Gutters
If birds are making nests in your gutters, it's because the gutter has enough depth of sludge and debris to build safely. A bird nest completely blocks water flow. The mess inside and under the gutter becomes severe. Bird droppings are acidic and accelerate corrosion and mortar failure. Once birds have nested, they return every year. You need the gutter cleared, and often a mesh fitted to prevent re-nesting.
Sign 7: You Haven't Had Gutters Cleaned in Over a Year
Even if you can't see obvious problems, if it's been more than twelve months since your gutters were professionally cleaned, they need attention. Most properties in Essex need gutter cleaning annually. Autumn is the worst season — leaves fall, gutters clog, and by winter you've got water damage in progress. A preventative clean is far cheaper than fixing damp and structural damage later.
How We Clean Gutters: SkyVac From the Ground
We use a SkyVac ground-level vacuum system. No ladders, no risk, no mess falling in your garden. The SkyVac removes debris from the gutter using suction, then we flush the gutters with water to clear any remaining sediment. We run a full flow test down every downpipe to confirm it's clear — not just the gutter itself. If the downpipe is blocked lower down, we find it and clear it. We don't leave until the whole system is flowing properly.
FAQ: How Often Should Gutters Be Cleaned?
Once a year is the minimum for most Essex homes. If you have large trees overhanging your roof, twice a year is better — once in late summer and once after leaves have fallen in autumn. After we've cleaned your gutters, we can advise on the right maintenance schedule for your property and the surrounding trees.
