DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
The biggest DIY mistake is sealing over old sealant. 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.
About our gutter sealing in The Wrythe
Open fascia and soffit joints spoil the roofline and can let weather in. We seal them in a colour to suit where one is available. We work on uPVC fascias, garage door frames and soffit joints, and the jobs we see most are wet patches on the wall under a gutter joint and stop ends leaking at the end of a run.
Outside work in London starts with access: side passages, upper floors and where to park. For a home in The Wrythe, tell us how high the joints are and how to reach the back of the building.
You’re covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Look for streaks or damp on the wall below gutters
- Don’t leave a sagging gutter
- Rest ladders on the wall, not the gutter
- Get leaks sealed before the wet months
Check the joints after heavy rain now and then. It’s the easiest time to see a leak.
If an end cap is dripping, deal with it before winter. A winter of drips can lead to damp patches inside.

What happens on the day
Before we leave, we go over the finished joints with you. The work normally takes an hour or two for a few joints, longer for a full run, depending on the size of the job. 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.
- First, we find the drip and check the gutter is not cracked or sagging.
- We clean out the joint and take out the old sealant.
- The area is dried so the sealant can bond.
- An exterior or gutter sealant is applied to the joint.
- The run is checked and any debris near the joints is cleared.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we are working on
- Mention if the joints have been sealed before

When to call us in The Wrythe
When a gutter sags, its joints open. Sealing won’t hold if the gutter keeps dropping, so the gutter needs refixing first.
People generally contact us after spotting one of these:
- Leaking gutter joints and stop ends
- Dripping gutter ends
- Damp patches inside below a leaking gutter
- Earlier gutter repairs that have peeled off
In the older streets around Bishop Andrewes Church, an extension built onto an older house moves differently, and the joint between them takes the strain.
What to look for in a quote
- Whether the sealant suits the joint
- How the joint is cleaned and prepared
- Are they insured?
- How the colour is chosen
Gutter sealing in The Wrythe: local notes
Historic houses like Nonsuch Mansion (about 2.9 miles west) are a reminder that the area around The Wrythe 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. 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.
Managing a site like Victor Seymour Infants' School? Then larger buildings have long runs of movement joint that eventually need resealing. The Wrythe is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
