Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Clear leaves and moss from the gutters
- Keep ladders off the guttering
- Look along the fascias for open joints
- Don’t leave a sagging gutter
Keep the gutters clear of leaves and moss so water doesn’t sit on the joints. Standing water strains every seal.
Early sealing limits how much water hits the wall. We’ll let you know if the gutter needs more than sealant.
When something else is needed
In fairness, there are a few things sealant will not fix:
- Gutters that have dropped or pulled away
- Blocked downpipes
- Guttering that needs replacing
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think.

Common problems we fix in Kingston Blount
Gutter joints depend on seals that wear out. Sun and cold make the gutter expand and contract and that movement opens up tired joints.
People generally contact us when they notice one of these:
- Garage door frames letting rain in
- Water running down the wall below the gutter
- Leaking gutter joints and stop ends
- Cracked sealant along roofline trims
Homes close to Church of the Nativity of the Blessed Virgin Mary include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.

What else we do in Kingston Blount
Walls and rooflines in Kingston Blount
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Adwell House (about 2.6 miles west) nearby, there’s older building stock in the area around Kingston Blount as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Letting a property close to Princes Risborough station? Then a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside. If you look after a building such as Aston Rowant Church of England Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Advice
Work for landlords, hotels and businesses
Landlords and letting agents in Kingston Blount can book us as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Why act early in Kingston Blount
A new garage door isn’t needed for a leaking frame. Resealing the frame joint is often enough, if the frame itself is sound. Older cottages and farmhouses around Kingston Blount can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll go through it with you.
