Leave it or put it right?
Replacing guttering is a much bigger job than sealing joints. If the gutter is sound and the drip is a joint a reseal is all it needs. If it’s broken or sagging, a gutter installer needs to look. Older cottages and farmhouses around Withermarsh Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

What gutter sealing looks like in Withermarsh Green
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Castle House (about 4.3 miles south-east) are a reminder that the area around Withermarsh Green has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
In and around Withermarsh Green, as anywhere, good gutter sealing starts with a clean, dry, properly prepared joint.

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Look for streaks or damp on the wall below gutters
- Check the gutters during heavy rain
- Don’t lean ladders against the gutter itself
- Sort out a dripping joint early
While checking gutters, glance at the fascia joints too. A small split is quicker to put right.
Leaking gutter joints get worse over time. The same spot gets soaked every time it rains, which can lead to staining and damp.
Do you need gutter sealing in Withermarsh Green?
End caps get knocked or pushed by water. If the seal fails, water escapes at the end.
Look out for these signs:
- Damp on an inside wall under a dripping gutter
- Earlier gutter repairs that have peeled off
- Leaking gutter joints and stop ends
- Cracked sealant along roofline trims
Historic houses such as Castle House, about 4.3 miles south-east, show how far back building around Withermarsh Green goes, and older homes nearby need a sealant that suits their walls.
Questions to ask before booking
- What insurance they hold
- How long the guarantee is
- What happens if they find a problem under the old sealant
- When the joint can take water or movement
Surface by surface
Soffit joints
We choose a sealant colour that suits the soffit, where one is available.
Gutter end caps
Stop ends hold back water at the end of a run. When their seal fails, they drip.
What we cannot put right
