The process
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours, depending on the number of joints and the access and we leave things clean and tidy. Somewhere like Derringstone needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by tracing the leak and checking the gutter itself is sound.
- The joint or trim is cleaned out and old sealant removed.
- 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
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property

Gutter sealing for homes and businesses in Derringstone
We don’t replace gutters, fascias or roofs. What sealant does is close joints; it won’t fix a broken bracket, a cracked section or a blocked downpipe. We work on soffit joints, gutter joints and gutter end caps, and people most often call us about fascia boards with gaps between them and old sealant on roofline trims that has split.
Outside joints can only be sealed when they’re dry, so work in Derringstone is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
Your job is guaranteed for a year, as with all our work.

What affects the cost of gutter sealing
Some jobs are bigger than they look, and some smaller. The main factors:
- How much old sealant there is and how hard it is to remove
- How easy the joints are to reach
- The product the joint needs
- Whether there’s mould to deal with
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and agree the price before starting.

Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us, and we’re fully insured.
Is it OK to seal over old sealant?
No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Will the old sealant be removed?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Is sealant enough for a gutter that has dropped?
No. If the gutter sags, the joints keep opening so it needs refixing before sealing.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme.
Why deal with it now?
A dripping stop end can soak the wall right through the wet months. Resealing it is a quick job before the damage spreads. Around Derringstone, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, phone 0345 464 0079 or email us and we will give you an honest view and a quote.

What gutter sealing looks like in Derringstone
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 Goodnestone Park (about 4.2 miles north-east) are a reminder that the area around Derringstone 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.
If you let a flat or house near Snowdown station, leaking gutter joints on a rental are best caught before they stain the walls. For site and facilities teams at buildings such as Barham Church of England Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For an older house near a landmark such as Church of St John the Baptist, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Aftercare tips
To keep the joints looking good and working properly:
- Keep an eye out for wet patches below a joint
- Keep ladders off the guttering
- Don’t leave a sagging gutter
- Make sure downpipes aren’t blocked
Have a look at the gutter during a downpour. Drips are easiest to spot while it’s raining.
A leaking stop end is best sealed before the wet months. A winter of drips can lead to damp patches.
