About our gutter sealing in World's End
We work across World's End on leaking gutter joints and roofline trims. Single-storey and low gutters are simple to reach and if it’s higher up, let us know and we will confirm what access is needed. If you are dealing with gaps along fascia and soffit joints and earlier gutter repairs that have peeled off, we can help.
London’s terraces and conversions often share walls, gutters and downpipes with their neighbours, so a leaking gutter joint or failed wall joint can affect more than one home. In a converted house in World's End, it’s worth checking who is responsible for the outside before booking.
You’re covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

Leave it or put it right?
Sealant will not clear a blocked downpipe. We look at what’s really happening and point you to the right trade if needed. 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.
Doing several joints on one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

How the job changes by surface
Soffit joints
Soffits sit under the eaves, where joints can open up. They’re sealed to tidy the line.
Gutter joints
A gutter joint has to cope with movement and standing water. A dedicated gutter sealant suits them.
What affects the cost of gutter sealing
Jobs vary more than people expect. What affects the quote:
- How much old sealant there is and how hard it is to remove
- The number and length of the joints
- Whether there’s mould to deal with
- How many rooms, windows or areas are involved
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before any work starts.
What we need to know
To make quoting easier, please include:
- The problem you’ve noticed
- Roughly how big the job is
- Whether it’s a home or a business
- Pictures of the joints, sent by email
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
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.
How the visit works
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take anything from an hour or two to a few hours. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- We look at the gutters, fascias and trims and agree the joints to seal.
- We clean out each joint.
- We make sure everything is dry.
- We apply exterior or gutter sealant and finish it neatly.
- We check our work before we leave.
How to prepare
- For business premises, tell us about site rules or sign-in
- Keep pets and children clear of the area while we work
- Tell us about any water getting in

World's End buildings and the weather
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 terraces and conversions, gutters and walls are often shared with the neighbours, so check who is responsible for the outside before booking.
If you look after a building such as Ashburnham Community School, its movement joints, gutters and trims need looking after like any other building’s. Rented homes near Imperial Wharf station change hands often, and leaking gutter joints on a rental are best caught before they stain the walls. As a London address, World's End can be tricky for parking: let us know about parking bays, permits or a driveway.

Your questions about gutter sealing in World's End
Is parking an issue for gutter sealing in World's End?
Parking in World's End, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Can you do gutter sealing in World's End?
Yes. We work across London and the South East, and World's End is part of that. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear quote.
How long does the job take?
As a guide, most jobs take a few hours, depending on the number of joints and the access. Bigger jobs take longer.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do you work on high-level gutters?
Single-storey work is the most straightforward. We’ll confirm the access for higher gutters once we know more.
Is sealant enough for a gutter that has dropped?
Sealant will not hold a sagging gutter. A gutter installer needs to refix it.

Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
