Gutter sealing in Strettington
Many dripping gutters are just a failed joint or end cap. The joint is cleaned, dried and resealed with a sealant made for guttering. If the gutter itself has failed, we say so. We’re often asked to deal with stop ends leaking at the end of a run and failed sealant on a garage door frame, across soffit joints, roofline trims and garage door frames.
External sealant needs dry, clean surfaces, so work around Strettington is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
Whatever the size of the job, you get the same 12-month guarantee in Strettington and across West Sussex.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Common problems we fix in Strettington
Overflowing gutters can look like leaking joints. A blocked downpipe makes water back up so we check the cause first.
Look out for any of the following:
- Failed sealant on a garage door frame
- End caps that drip every time it rains
- Streaks down the brickwork from a leaking joint
- Trim joints where the sealant has failed
If you let a flat or house near Chichester station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.
What your quote should include
- How the joint is cleaned and prepared
- Whether you can choose the colour
- The length of the guarantee
- When the joint can take water or movement
How it works
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the work takes an hour or two for a few joints, longer for a full run in most cases. Somewhere as small as Strettington, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we agree which joints need sealing.
- We clean out each joint.
- We make sure everything is dry.
- We apply exterior or gutter sealant and finish it neatly.
- The joints are checked once sealed.
How to prepare
- Clear items away from the joints we’re working on
- Let us know about earlier repairs to the joints
- For indoor joints, keep the area dry beforehand if you can

Strettington buildings and the weather
Historic houses like Goodwood House (about 0.9 miles north-west) are a reminder that the area around Strettington 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you live in an older home near St Andrew's Church, older walls, gutters and the joints where extensions meet them need a flexible sealant. For site and facilities teams at buildings such as Boxgrove CofE Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Will you come out to Strettington?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
How long should I leave it?
Different products cure at different speeds, so please follow the time we give you when we finish.
Do you remove the old sealant?

When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Roof leaks, slipped tiles or failed flashing (a roofer’s job)
- Rotten or damaged fascia boards
- Downpipes that are blocked or broken
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think before booking.
Surfaces we seal
- uPVC fascias
- Gutter end caps

- Garage door frames
- Roofline trims
- Gutter joints
How to look after the new joints
A little care helps the new joints last. We recommend:
- Look at the gutters while it’s raining
- Sort out a dripping joint early
- Keep the gutters clear of debris
- Have sagging gutters refixed early
If a gutter starts to sag, get the brackets looked at. Movement will pull the joints open again.
A drip from a gutter joint won’t stop on its own. The same spot gets soaked every time it rains and that can cause damp inside.
What affects the quote in Strettington
We do not publish a price list, because no two jobs are the same. The quote depends on:
- The amount of work
- The product the joint needs
- How many rooms, windows or areas are involved
- The old material and how stubborn it is
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, ring 0345 464 0079 or send us an email and we will give you an honest view and a quote.
Helping us quote
Photos help, but a description is a good start. Please mention:
- Access, such as stairs, a lift or height
- A few pictures by email, if you can
- How many joints, rooms or windows are involved
- The address or postcode of the job
It all starts with a short chat. Describe the problem, the location and the size of the job. When it suits you, call 0345 464 0079 or send us an email.
Leave it or put it right?
Leaving a leaking end cap can send water down the wall all winter. Resealing it is a quick job before the damage spreads. Where a wall is exposed, as many are in small places like Strettington, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and agree the price before starting.
