- Damp patches inside below a leaking gutter
- Fascia boards with gaps between them
- Old gutter sealant that has let go
How we handle gutter sealing in Duncton
Gutter and fascia replacement isn’t our trade, and nor is roofing. What sealant does is close joints and it can’t mend broken brackets, split sections or blocked downpipes. If you’re dealing with dripping gutter ends and fascia boards with gaps between them, we can help, whatever the surface.
Around Duncton, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.
We stand behind the work with a one-year guarantee, so you are covered after we have gone.

How the job changes by surface
Garage door frames
Garage door frames let rain in when their sealant fails. It’s removed and renewed.
Roofline trims
Sealing roofline trims is joint work only. Roofing problems need a roofer.
Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
What happens if it’s left?
You do not need new fascias just because the joints have opened. A neat seal closes the gaps if the boards are sound. Around Duncton, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

Gutter sealing in Duncton: local notes
Historic houses like Bignor Roman Villa (about 2.4 miles south-east) are a reminder that the area around Duncton 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.
Schools such as Duncton CofE Junior School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes an hour or two for a few joints, longer for a full run.

When to call us in Duncton
When a gutter sags, its joints open. Resealing a sagging joint will not last, so the gutter needs refixing first.
Look out for these signs:
- End caps that drip every time it rains
- Failed sealant on a garage door frame
- Streaks down the brickwork from a leaking joint
- Trim joints where the sealant has failed
In the older streets around Church of Holy Trinity, an extension built onto an older house moves differently, and the joint between them takes the strain.
What your quote should include
- What the quote includes, VAT included or not
- How the surfaces are prepared before sealing
- Whether all the old sealant comes out first
- Who does the work, and how experienced they are
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Watch for drips in a downpour
- Look along the fascias for open joints
- Look for streaks or damp on the wall below gutters
- Keep the gutters clear of debris
Keep the gutters clear of leaves and moss, so water drains away past the joints. Standing water strains every seal.
A leaking garage frame lets water reach stored items. A reseal sorts it.
When something else is needed
To be straight with you, some problems need a different trade:
- Problems with the roof covering
- Gutters that have dropped or pulled away
- Fascias that need replacing
