Leave it or put it right?
Water from a leaking joint hits the same spot every time. Over time that can stain brickwork, mark render and encourage damp so early sealing is worthwhile. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
The cost depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.

Gutter sealing for homes and businesses in Anerley
Our work covers gutter joints and end caps as well as fascias and soffits, along with roofline trims and garage door frames. It’s all about the joints rather than new guttering. Typical jobs include water dripping where gutter sections meet and garage door frames letting rain in, on gutter end caps, gutter joints and soffit joints.
Modern London flats rely on sealed movement joints and cladding joints. 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 with the work, just as it does everywhere we cover.

Should I try it myself first?
If you’ve already had a go yourself, that is fine. We cut it out and start again.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Anerley buildings and the weather
The South East is one of 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 Kingswood House (about 1.3 miles north-west) are a reminder that the area around Anerley 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.
For landlords with property near Anerley station, leaking gutter joints on a rental are best caught before they stain the walls. For site and facilities teams at buildings such as James Dixon Primary School, its movement joints, gutters and trims need looking after like any other building’s.

The process
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take anything from an hour or two to a few hours. In a London area like Anerley, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- First, we find the drip and check the gutter is not cracked or sagging.
- Old sealant and dirt are removed from the joint.
- The area is dried so the sealant can bond.
- An exterior or gutter sealant is applied to the joint.
- We check the run and clear any debris we find while we’re there.
How to prepare
- Mention any tricky access
- Tell us if parking is tricky
- Where the joints are inside, avoid wetting them before we arrive

Related advice
What the job involves on each surface
Gutter end caps
A leaking end cap sends water straight down the wall. It’s a quick reseal.
Roofline trims
We seal the trims, not the roof. A roofer deals with the roof itself.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Watch the wall under the gutters for staining
- Check the gutters during heavy rain
- Clear leaves and moss from the gutters
- Glance at the soffit joints now and then
Give the sealant the cure time we tell you before poking or cleaning near it.
If an end cap is dripping, deal with it before winter. Water down the wall all winter can cause damp inside.
For landlords and businesses
Hotels need rooms back in use, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
We also work for property managers and facilities teams. Several sites can go on one quote, and we’re fully insured for the work.

When to call us in Anerley
Gutter joints rely on seals that age. Temperature changes make gutters move and that movement opens up tired joints.
Keep an eye out for any of the following:
- Stop ends leaking at the end of a run
- Old gutter sealant that has let go
- Damp on an inside wall under a dripping gutter
- Drips from gutter joints and end caps
In the older streets around St Paul's, older walls, gutters and the joints where extensions meet them need a flexible sealant.

- Who does the work, and how experienced they are
- What happens if the job turns out different

Common questions in Anerley
Is parking an issue for gutter sealing in Anerley?
Parking in Anerley, 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 Anerley?
Yes, Anerley is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear price.
Can you do several jobs on one visit?
Yes. More than one area can be quoted together.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Can sealant stop a sagging gutter leaking?
It will not last. The joint will pull apart so the gutter has to be refixed first.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.

It depends on the job, so we quote each one individually. To get one, phone 0345 464 0079 or send us an email with a short description of the job.
Do you work on high-level gutters?
Single-storey work is the most straightforward. We will confirm the access for higher gutters once we know more.
