About our gutter sealing in Foxbury
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. If you have cracked sealant along roofline trims and open joints in fascias and soffits, we can help.
Working on the outside of a London home means planning access: shared paths, upper floors and parking. In Foxbury, joints up high may need ladders or other access, which is worth talking through when you book.
All our work comes with our one-year guarantee, wherever you are in Greater London.

Gutter sealing in Foxbury: local notes
In terraces and conversions, gutters and walls are often shared with the neighbours, so check who is responsible for the outside before booking. Historic houses like Eltham Palace (about 2.6 miles north-west) are a reminder that the area around Foxbury has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
If you let a flat or house near Sidcup station, a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside. Schools such as Chislehurst School for Girls are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. If you live in an older home near Christ Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
What affects the quote in Foxbury
We quote each job individually. This is what makes a difference:
- Access and height
- How much there is to do
- Which sealant suits the joint
- Mould in or behind the old joints
The cost depends on the amount of work, how much old material has to come out and access to the work. You will have a clear quote before any work starts.
Helping us quote
There’s no need for technical detail. Just tell us:
- Where the property is
- A few pictures by email, if you can
- How we’d reach the joints
- Whether it has been sealed before
For a quote, call 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. You’ll have a clear quote before any work starts.

What we do, step by step
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours, depending on the number of joints and the access. In a London area like Foxbury, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- First we agree which joints need sealing.
- Each joint is cleaned and any old sealant removed.
- The joints are dried.
- The sealant is applied and finished.
- The joints are checked once sealed.
Getting ready for the visit
- Tell us if parking is tricky
- Move anything stored near the joints
- Where the joints are inside, avoid wetting them before we arrive

Advice
What happens if it’s left?
Sealing over a dirty, wet joint is a quick fix that rarely lasts but it tends to peel off. Proper preparation is the difference. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in Foxbury.
What you pay reflects the work, not guesswork. That is why we ask about the job first and agree the price before starting.

How to look after the new joints
After the cure time, these simple habits help:
- Rest ladders on the wall, not the gutter
- Check fascia and soffit joints for gaps
- Clean out the gutters once or twice a year
- Sort out a dripping joint early
If a gutter starts to sag, get the brackets looked at. Movement will pull the joints open again.
A leaking stop end is best sealed before the wet months. A winter of drips can lead to damp patches inside.
How the job changes by surface
Gutter joints
A gutter joint has to cope with movement and standing water. A dedicated gutter sealant suits them.
Roofline trims
Trims along the roofline are often finished with sealant. Split sealant lets water in.
Common questions in Foxbury
Do you work for landlords with property near Sidcup station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
Is Foxbury in your area for gutter sealing?
Yes. Our work covers London and the South East, and Foxbury is part of that. You can phone 0345 464 0079 or send us an email and let us know what needs doing, and we will give you a clear price.
Can new sealant go over the old?
No, it won’t last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Is it possible to stop a gutter joint dripping with sealant?
Yes, as long as the gutter itself is in good order. We clean and dry the joint before sealing so the sealant bonds.
What should I tell you?
A short description and the location, plus photos if you have them. We will ask anything else we need to know.
How long does the job take?
It depends on the size of the job, but as a guide it takes a few hours, depending on the number of joints and the access. We will tell you when we quote.
What guarantee comes with the job?
There’s a 12-month guarantee on every job, gutter and fascia work included.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all.
