Slaugham Gutter Sealing

- Wet patches on the wall under a gutter joint
Surface by surface
Roofline trims
Trims along the roofline are often finished with sealant. When it splits, water can get behind.
uPVC fascias
We seal fascia joints, not replace the boards. Damaged boards need replacing by an installer.
About our gutter sealing in Slaugham
Garage door frames let rain in when the sealant around them fails. We cut out the old sealant and reseal the frame with an exterior sealant. Common call-outs are for cracked sealant along roofline trims and old gutter sealant that has let go, across roofline trims, soffit joints and uPVC fascias.
External sealant needs dry, clean surfaces, so work around Slaugham is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
Whatever the size of the job, it’s backed by our 12-month guarantee in Slaugham and across West Sussex.

Outside joints around Slaugham
With historic houses such as Tyes Place (about 1.8 miles east) nearby, there’s older building stock in the area around Slaugham as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around St Mary's Church, the joints between older walls, newer extensions and the roofline need a sealant that can move. If you let a flat or house near Balcombe station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

Why deal with it now?
Replacing guttering is a much bigger job than sealing joints. If the gutter is sound and the drip is a joint, resealing is the sensible fix. If it’s broken or sagging, a gutter installer needs to look. Around Slaugham, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint normally makes the job bigger, not smaller. If you’re unsure, ring 0345 464 0079 or email us for an honest opinion and a quote.

Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Do not leave a sagging gutter
- Keep downpipes clear
- Check fascia and soffit joints for gaps
- Deal with a drip before winter
Have a look at the gutter during a downpour. It’s the easiest time to see a leak.
Early sealing limits how much water hits the wall. If we find a bigger problem, we will tell you.
How it works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. It generally takes anything from an hour or two to a few hours. In a small place like Slaugham, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we find the drip and check the gutter isn’t cracked or sagging.
- We clean out the joint and take out the old sealant.
- The joint is dried, because sealant won’t bond to a wet surface.
- We seal the joint with a sealant made for gutters and outdoor use.
- The run is checked and any debris near the joints is cleared.
Getting ready for the visit
- Keep children and pets away from the work area
- Move anything stored near the joints
- Let us know about earlier repairs to the joints

Advice
Do you need gutter sealing in Slaugham?
Sealant laid on a wet or dirty joint fails early. Rushed repairs often don’t last long for this reason.
Most people get in touch after spotting one of these:
- Open joints in fascias and soffits
- Failed sealant on a garage door frame
- End caps that drip every time it rains
- Old sealant on roofline trims that has split
For site and facilities teams at buildings such as Warninglid Primary School, larger buildings have long runs of movement joint that eventually need resealing.
What to look for in a quote
- Whether all the old sealant comes out first
- Which colour the sealant will be
- Whether the sealant suits the joint
- How long the guarantee is

Common questions in Slaugham
Is Slaugham in your area for gutter sealing?
Yes, Slaugham is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing.
Is Slaugham within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you clean gutters?
We clean the joints we are sealing and clear debris we find nearby. Cleaning the whole run is a different job.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Is sealing fascia joints something you do?
Yes. We seal open joints along fascias and soffits in a colour to suit.
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 you work on high-level gutters?
Low-level work is easiest. We’ll confirm the access for higher gutters before we book.
Where is Mr Mastic based?
