Southwark Gutter Sealing
Our applicators work in Southwark on sealing leaking gutter joints, end caps, fascias, soffits and roofline trims. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Open joints in fascias and soffits
- End caps that drip every time it rains
- Old sealant on roofline trims that has split
Why act early in Southwark
Sealing over a dirty, wet joint is a quick fix that rarely lasts but it tends to peel off. Cleaning out and drying the joint first is what makes it last. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Southwark, the repair is bigger than a sealant job.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and send you a clear quote before any work starts.
What you get with us
- One-year guarantee on every job
- Colour picked to suit the job
- 180+ five-star Google reviews
- Any old sealant cut out fully, not covered over

Gutter sealing in Southwark, done properly
A drip at a gutter joint is easy to ignore, but each shower sends water to the same place. Sealing it is quick if the gutter is otherwise in good order. If you have open joints in fascias and soffits and drips from gutter joints and end caps, we can put it right.
Newer London blocks are built with movement joints in brick and render, and with cladding joints sealed with mastic. Period houses have different weak points, such as gutter joints, trims and the line where an extension meets the old wall, and both kinds of building are found across London.
A 12-month guarantee comes as standard, so you are covered after we have gone.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
How the visit works
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the work takes an hour or two for a few joints, longer for a full run for a typical job. In Southwark, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- We find where the water is coming from and check the gutter is sound.

Advice
Outside joints around Southwark
Historic houses like Mansion House (about 0.9 miles north) are a reminder that the area around Southwark has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. 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.
Letting a property close to Elephant & Castle station? Then a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside. For an older house near a landmark such as Borough Welsh Congregational Chapel, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Questions from Southwark
Do you cover Southwark for gutter sealing?
Yes, Southwark is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or drop us an email and tell us what needs doing.
Do you work for landlords with property near Elephant & Castle station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear price.
Is sealing fascia joints something you do?
Yes. Our work is the joints and we’ll let you know if a board has failed.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Will the old sealant be removed?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
How long will you be here?
A typical job takes an hour or two for a few joints, longer for a full run, including the preparation. We will confirm how long when we quote.
What we are called out for in Southwark
Sealant on fascias and trims weathers like any outdoor joint. It hardens, shrinks and splits after some years.
Signs it’s time to call us include:
- Cracked sealant along roofline trims
- Water running down the wall below the gutter
- Damp on an inside wall under a dripping gutter
- Dripping gutter ends
Managing a site like Charles Dickens Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.
