How we handle gutter sealing in Great Kingshill
Many dripping gutters are just a failed joint or end cap. We clean out the joint, dry it and reseal it with a sealant made for guttering. If the gutter itself has failed, we say so. We are often asked to deal with open joints in fascias and soffits and trim joints where the sealant has failed, on soffit joints, gutter joints and garage door frames.
In a village or hamlet like Great Kingshill, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
What gutter sealing looks like in Great Kingshill
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Hughenden Manor (about 2.1 miles south-west) nearby, there’s older building stock in the area around Great Kingshill as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
For landlords with property near Great Missenden station, leaking gutter joints on a rental are best caught before they stain the walls. If you look after a building such as Great Kingshill Church of England Combined School, larger buildings have long runs of movement joint that eventually need resealing.

Common problems we fix in Great Kingshill
Sealant on fascias and trims weathers like any outdoor joint. It hardens, shrinks and splits over time.
These are the problems we are asked about most:
- Rain getting in around a garage door
- Damp patches inside below a leaking gutter
- Old gutter sealant that has let go
- Gaps along fascia and soffit joints
For an older house near a landmark such as Church of the Good Shepherd, the joints between older walls, newer extensions and the roofline need a sealant that can move.

What we do, step by step
When we arrive, we start by going over the job with you, so you know exactly what we’re doing. We protect the surfaces around the joints before we start. The work usually takes a few hours, depending on the number of joints and the access. Somewhere like Great Kingshill needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by tracing the leak and checking the gutter itself is sound.
- The joint or trim is cleaned out and old sealant removed.
- The area is dried so the sealant can bond.
- An exterior or gutter sealant is applied to the joint.
- We check the run and clear any debris we find while we’re there.
Getting ready for the visit
- Keep pets and children clear of the area while we work

How the job changes by surface
Gutter end caps
We seal end caps from the inside where we can reach, after cleaning and drying.
uPVC fascias
Our work is the joints, not new fascias. Damaged boards need replacing by an installer.
Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Get a dropping gutter looked at quickly
- Glance at the soffit joints now and then
- Check that water runs out of the downpipes
- Keep ladders off the guttering
Give the sealant the cure time we tell you before poking or cleaning near it.
Once roofline sealant splits, water can get behind it. Resealing early protects the boards and the wall below.
