- The old material and how stubborn it is
- Mould in or behind the old joints
- How many areas need sealing
- Which sealant suits the joint
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.

Gutter sealing in Keymer, done properly
We work across Keymer on leaking gutter joints and roofline trims. Single-storey and low gutters are simple to reach, and for higher work, tell us about access and we will confirm what’s needed. We work on garage door frames, uPVC fascias and gutter joints, and people most often call us about wet patches on the wall under a gutter joint and end caps that drip every time it rains.
Around Keymer, garages, outbuildings and extensions all add to the joints on the outside of a home. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.
Big or small, it’s backed by our 12-month guarantee in Keymer and across West Sussex.

Surface by surface
Gutter end caps
Drips from a stop end run down the brickwork. It’s a quick reseal.
uPVC fascias
Gaps in fascias spoil the roofline. Sealing them closes the gap.
Common problems we fix in Keymer
End caps get knocked or pushed by water. Once the seal behind them fails, they drip and runs down the wall.
If you can see any of these, it’s time to have the joints looked at:
- Damp on an inside wall under a dripping gutter
- Failed sealant on a garage door frame
- Earlier gutter repairs that have peeled off
- Old sealant on roofline trims that has split
If you look after a building such as The Windmills Junior School, its movement joints, gutters and trims need looking after like any other building’s.

Why it’s worth doing now in Keymer
Water from a leaking joint hits the same spot every time. Left, it can stain walls and lead to damp so early sealing is worthwhile. In an older home around Keymer, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Why book with us
- Sanitary silicone with an anti-fungal additive in wet areas
- White, clear, grey or another colour, product permitting
- Old sealant always removed completely
- Homes, businesses and hotels

Common questions in Keymer
Do you cover Keymer for gutter sealing?
Yes. Our work covers London and the South East, and Keymer is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing, and we will give you a clear price.
I let a flat near Hassocks station. Can you help?
Yes, we work for letting agents and landlords. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses and we’re fully insured.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Do you remove the old sealant?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Do you work on high-level gutters?
That depends on the building. Let us know the height and the ground below when you phone 0345 464 0079 or email us.
How long does the job take?
Typically it takes a few hours, depending on the number of joints and the access. Bigger jobs take longer.

Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Outside joints around Keymer
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as St Cosmas and St Damian Church, an extension built onto an older house moves differently, and the joint between them takes the strain. Letting a property close to Hassocks station? Then a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.

Aftercare tips
So the new joints stay in good condition:
- Clear leaves and moss from the gutters
- Check that water runs out of the downpipes
- Watch for drips in a downpour
- Glance at the soffit joints now and then
If a gutter starts to sag, get the brackets looked at. Movement will pull the joints open again.
Rain getting in round a garage door frame can damage what’s stored inside. Resealing the frame is a quick job.
What we do, step by step
You don’t need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the work takes a few hours, depending on the number of joints and the access for a typical job. For a job in Keymer, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First we agree which joints need sealing.
- We clean out each joint.
- We make sure everything is dry.
- The sealant is applied and finished.
- The joints are checked once sealed.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
