Home›Gutter, Fascia & Soffit Cleaning›Knaphill
Green film, black tiger stripes and years of grime can make a well-kept house look neglected. We wash the outside of your gutters, fascias and soffits so the whole roofline of your Knaphill home looks bright and fresh again.
White uPVC is supposed to look crisp, but on a lot of houses it slowly turns grey, green or streaky. That discolouration sits on the outside of the gutters, along the fascia boards they are fixed to and on the soffits underneath the eaves. Our fascia and soffit cleaning in Knaphill washes all three, removing algae, black streaks, cobwebs and traffic grime so the roofline matches the rest of a well-kept home.
We use a gentle cleaning solution suitable for uPVC, worked in with soft brushes and then rinsed thoroughly with clean water. Wherever possible the whole job is done from the ground on high-reach poles, so there is no need for ladders against your windows or flower beds. Brown, black and grey plastics come up just as well as white, and painted timber can be washed gently too. Many customers pair this with having the inside of the gutters cleared on the same visit, which makes sense because both use the same access and it leaves the entire roofline sorted in one go.

The same trees that give Knaphill its leafy character are the main reason rooflines discolour here. Pine, oak and birch drip sap and pollen, and they shade the eaves for much of the day. Shaded, slightly damp surfaces are exactly what green algae needs, so the northern and tree-facing sides of houses tend to turn green first. Houses close to Horsell Common or with woodland at the end of the garden often show it within a couple of years of a wash.
Black tiger stripes are a slightly different problem. They form when rain carrying dirt and atmospheric grime spills over the front edge of the gutter and runs down the face in the same lines time after time. Gutters that overflow because they are full of needles make the stripes much worse. On busier routes such as the main road through the village, a fine layer of traffic film builds up on fascias and soffits as well, dulling white plastic to a flat grey.
The age of a Knaphill house changes the picture again. Many of the 1980s and 1990s homes around Knaphill and neighbouring Goldsworth Park have deep white soffits and wide fascias that show every mark, while modern houses often use dark grey uPVC where algae shows up as a chalky green bloom. The moist air along the Basingstoke Canal helps algae cling on, so south-facing walls stay cleaner than those facing the water. We wash rooflines throughout the GU21 area around Knaphill.
Careful, low-impact cleaning that respects your plastics and your garden.
From your photos or on arrival we check the colour and condition of the gutters, fascias and soffits and note heavy staining, so the right solution strength is used on each elevation.
A gentle, uPVC-safe solution is applied to loosen algae, grime and streaks, and left for a short time to work into the surface rather than relying on force.
Soft brushes on high-reach poles work over the gutter faces, fascia boards and soffit undersides, paying particular attention to stubborn tiger stripes along the front edge.
Everything is rinsed with clean water so no residue is left to attract new dirt, then we check the finish from the ground and clean up around the house.

A full roofline wash takes in more than just the gutters, and we like to be clear about the scope before we arrive. As standard we clean:
We are cleaning the outside surfaces here, so if the gutters themselves are full of debris it is worth having them cleared on the same day. That stops dirty water overflowing and re-staining the fresh fascias the next time it rains, undoing the work within weeks.
We price each property individually, based on what we can see in your photos. The main considerations are:
Send photos showing each side of the house and we will reply with a clear, fixed price, normally the same day and with no obligation at all.
Nearly always. Tiger stripes are a bonded layer of grime rather than a stain in the plastic, and the right cleaning solution with soft brushing lifts the vast majority. Very old, weathered uPVC can occasionally keep a faint shadow, which we will mention beforehand if we spot it.
It is almost always shade and moisture. Sides facing north, overhung by pines or oaks, or looking towards the canal stay damp for longer, and algae grows much faster there. The sunny side dries out quickly, so it tends to stay cleaner.
No. High pressure can force water behind soffit boards and into vents, and it can damage older plastics. We use a gentle cleaning solution, soft brushes and a low-pressure rinse, which cleans thoroughly without putting your roofline at risk. It is slower, but far safer.
Yes, and it is the combination we recommend. Clearing the debris first stops dirty water spilling over the front edge, then washing the outside leaves the whole roofline looking fresh. Doing both together also saves arranging two separate visits. One visit, one tidy-up.
That depends on shade and tree cover. Open, sunny houses can stay bright for a few years, whereas homes under pines or beside woodland around Knaphill may start to green up sooner. Keeping the gutters clear so they do not overflow helps the finish last longer.
We use a gentle solution designed for uPVC and rinse thoroughly with water afterwards. We take care around plants and ponds, and it is sensible to keep pets indoors while we are working and until the surfaces have been rinsed.
