How we handle gutter sealing in Keston
We work across Keston on leaking gutter joints and roofline trims. Low-level work is straightforward and if it’s higher up, let us know and we’ll confirm what access is needed. We work on uPVC fascias, gutter joints and soffit joints, and common reasons people get in touch are cracked sealant along roofline trims and gaps along fascia and soffit joints.
In London terraces and converted houses, gutters and walls are often shared with the house next door, so one failed joint can cause damp for more than one household. In a converted house in Keston, it’s worth checking who is responsible for the outside before booking.
You get a one-year guarantee, the same in Keston as everywhere else we work.

The process
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes anything from an hour or two to a few hours, depending on the size of the job. In Keston, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- We look at the gutters, fascias and trims and agree the joints to seal.
- We clean out each joint.
- The joints are dried.
- We apply exterior or gutter sealant and finish it neatly.
- The joints are checked once sealed.
How to prepare
- Mention any leaks or damp you’ve noticed

Can I do it myself?
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Gutter sealing in Keston: local notes
With historic houses such as Down House (about 2.2 miles south-east) nearby, there’s older building stock in the area around Keston as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around Keston Parish Church, an extension built onto an older house moves differently, and the joint between them takes the strain. For landlords with property near Hayes (Kent) station, a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside. As a London address, Keston can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Make sure downpipes aren’t blocked
- Do not leave a sagging gutter
- Get leaks sealed before the wet months
- Watch the wall under the gutters for staining
A sagging gutter needs its brackets checked. If it drops, the joints will open.
A drip from a gutter joint will not stop on its own. The same spot gets soaked every time it rains, which can lead to staining and damp.
Surface by surface
Gutter end caps
Stop ends hold back water at the end of a run. A failed seal makes them leak.
Gutter joints
Gutter joints move and sit in water. A dedicated gutter sealant suits them.
Why act early in Keston
If the problem is a blocked downpipe, sealing will not help. We look at what’s really happening and tell you if something else is needed. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Keston, the repair is bigger than a sealant job.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
