External mastic in Warninglid: local notes
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Tyes Place (about 1.8 miles north-east) nearby, there’s older building stock in the area around Warninglid as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.

About our external mastic in Warninglid
For buildings in Warninglid, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. If you have movement joints with cracked, split or missing sealant and panel joints letting water in, we can help, on brickwork movement joints, façade panels and joints between brick and frames alike.
Outside joints can only be sealed when they’re dry, so work in Warninglid is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
All our work is covered by our 12-month guarantee, wherever you are in West Sussex.

Do you need external mastic in Warninglid?
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.
Any of these means the joints need attention:
- Failed seals between different materials
- Joints where the bead has come unstuck
- Brick movement joints where the sealant has split
- Joints pointed up with cement by mistake
Rented homes near Balcombe station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Honest limits
It helps to know what we cannot do:

- Render that is blown, hollow or coming away

Your questions about external mastic in Warninglid

Will the new joint stand out?
The sealant colour is picked to suit the wall so the joint blends in. Exterior sealants come in a good range of colours.
Is there any odour?
There can be a smell while the sealant cures. Ventilation helps.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Why deal with it now?
A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and does not last, so it pays to do it properly once. Around Warninglid, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, call 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.
