Gutter sealing in Selmeston, done properly
Gutter and fascia replacement isn’t our trade, and nor is roofing. What sealant does is close joints and it cannot mend broken brackets, split sections or blocked downpipes. If you are dealing with earlier gutter repairs that have peeled off and failed sealant on a garage door frame, we can put it right, whatever the surface.
Around Selmeston, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Questions from Selmeston
Will you come out to Selmeston?
Yes, Selmeston is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you do gutter sealing in Selmeston?
Yes. Our work covers London and the South East, and Selmeston is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we will give you a clear price.
How long should I leave it?
Cure times vary by product and the conditions. We tell you how long to leave it before we go.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access.
Where is Mr Mastic based?
Our base is Crawley. We work across South East England, London and Scotland.
How much does gutter sealing cost in Selmeston?
It depends on the job, so we quote each one individually. To get one, ring 0345 464 0079 or email us and let us know what needs doing and where.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Can you fit new guttering?
No. We seal leaking joints and trims. A gutter installer or roofer deals with replacement.
Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
What happens if it’s left?
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. Older cottages and farmhouses around Selmeston can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
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.

What gutter sealing looks like in Selmeston
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Charleston Farmhouse (about 1.2 miles west) nearby, there’s older building stock in the area around Selmeston as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
If you live in an older home near The Parish Church of St Mary, an extension built onto an older house moves differently, and the joint between them takes the strain. Letting a property close to Berwick (Sussex) station? Then a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

What’s near Selmeston
Typical jobs here are in homes near The Barley Mow pub and the streets around them. For rail, the closest station is Berwick (Sussex) station, about 1 mile east. A little further out are Drusillas Museum (1.8 miles south-east) and Chailey Heritage Marine Hospital (5.3 miles south-west). Not far away are Firle Beacon.
DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We cut it out and start again.
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. All the old material has to come out first.
What happens on the day
You do not need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the job takes anything from an hour or two to a few hours in most cases. For a village or hamlet like Selmeston, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at where the water is coming from and check the gutter is not broken or sagging.
- Old sealant and dirt are removed from the joint.
- The area is dried so the sealant can bond.
- We seal the joint with a sealant made for gutters and outdoor use.
- We look along the gutter and clear debris around the joints.
How to prepare
- Let us know about stairs, lifts or work at height
- Mention any leaks or damp you’ve noticed
- Let us know about earlier repairs to the joints
