How we handle gutter sealing in Stansted
A drip at a gutter joint is easy to ignore, but the water lands on the same spot every time it rains. Resealing it is a small job while the gutter is still sound. If you’re dealing with stop ends leaking at the end of a run and cracked sealant along roofline trims, we can help.
In a village or hamlet like Stansted, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
Every job is covered by a one-year guarantee, wherever you are in Kent.

What we do, step by step
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes an hour or two for a few joints, longer for a full run and we leave things clean and tidy. Somewhere like Stansted needs a little journey planning: let us know about lanes, gates and parking. 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.
- Old sealant and dirt are removed from the joint.
- The area is dried so the sealant can bond.
- An exterior or gutter sealant is applied to the joint.
- The run is checked and any debris near the joints is cleared.

Gutter sealing in Stansted: local notes
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Lullingstone Castle (about 4.7 miles west) are a reminder that the area around Stansted has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
In the older streets around Church of St Mary, older walls, gutters and the joints where extensions meet them need a flexible sealant. For landlords with property near Borough Green & Wrotham station, a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.

Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Why it’s worth doing now in Stansted
