Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.

Questions from Up Somborne
Is Up Somborne in your area for gutter sealing?
Yes. We work across London and the South East, and Up Somborne is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we’ll send you a clear quote.
Will you come out to Up Somborne?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you seal gaps in fascias and soffits?
Yes, often alongside gutter joints. The gaps are cleaned and sealed neatly.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Can a leaking gutter joint be sealed?
Yes, as long as the gutter itself is in good order. We clean and dry the joint before sealing so the seal holds.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
How long will you be here?
A typical job takes a few hours, depending on the number of joints and the access. We’ll confirm how long when we quote.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours, depending on the number of joints and the access.

Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Check the gutters during heavy rain
- Get leaks sealed before the wet months
- Clear leaves and moss from the gutters
- Keep ladders off the guttering
Make sure downpipes aren’t blocked, so water can get away. Blockages push water back along the gutter.
Leaking gutter joints get worse over time. Water keeps hitting the same part of the wall and that can cause damp inside.
Why it’s worth doing now in Up Somborne
Sealing over a dirty, wet joint is a quick fix that rarely lasts, but it soon lets go. Cleaning out and drying the joint first is what makes it last. Older cottages and farmhouses around Up Somborne can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: 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 explain what it covers.

Up Somborne buildings and the weather
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to All Saints Church include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. In and around Up Somborne, as anywhere, good gutter sealing starts with a clean, dry, properly prepared joint.
