Gutter sealing in Bellingham
Many dripping gutters are just a failed joint or end cap. We clean out the joint, dry it and reseal it using a gutter sealant. If the gutter itself has failed, we say so. If you have earlier gutter repairs that have peeled off and trim joints where the sealant has failed, we can help, on gutter joints, soffit joints and gutter end caps alike.
London’s terraces and conversions often share walls, gutters and downpipes with their neighbours, so one failed joint can cause damp for more than one household. For a flat in Bellingham, check the lease for who looks after the outside.
Every job comes with a one-year guarantee, wherever you are in Greater London.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll quote.
Landlords and agents in Bellingham can book us as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
What happens if it’s left?
A bead squeezed onto a wet joint might hold for a while but it tends to peel off. Proper preparation is the difference. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

What happens on the day
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from an hour or two to a few hours and we leave things clean and tidy. In Bellingham, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- First we trace the drip and check the gutter isn’t damaged.
- The old sealant and dirt are cleaned out of the joint.
- We dry the joint so the new sealant can bond.
- We seal the joint with a sealant made for gutters.
- We check the run and clear debris near the joints.
Getting ready for the visit
- Mention if the joints have been sealed before
- Mention any leaks or damp you’ve noticed
- Try not to wet indoor joints just before the visit

Related advice
Gutter sealing in Bellingham: local notes
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. In terraces and conversions, gutters and walls are often shared with the neighbours, so it’s worth agreeing who is responsible before work starts.
Bellingham is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. Schools such as Elfrida Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you live in an older home near St Dunstan, an extension built onto an older house moves differently, and the joint between them takes the strain.

What about gutters on a second or third storey?
Single-storey work is the most straightforward. For anything higher, we will confirm what access is needed before we book.
Is it OK to seal over old sealant?
No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
Will you clear out my gutters?
We clean the joints we are sealing and any debris nearby is cleared. Cleaning the whole run is a different job.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep downpipes clear
- Look at the gutters while it’s raining
- Glance at the soffit joints now and then
- Do not leave a sagging gutter
If a gutter starts to sag, get the brackets looked at. If it drops, the joints will open.
A drip from a gutter joint will not stop on its own. Water keeps hitting the same part of the wall, which can lead to staining and damp.
What sealant work can’t fix
To be straight with you, some problems need a different trade:
- Problems with the roof covering
- Brackets that have snapped or loosened
- Cracked, split or warped gutter sections
If you are not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer.
