How the job changes by surface
External movement joints
Movement joints are cleaned out, backed with rod and resealed with a sealant of the right movement class.
Window and door perimeters on blocks
Window and door perimeters are where most mastic failure shows. Old perimeter mastic is removed, the joint prepared and new sealant tooled in.
Mastic sealing in Mowshurst, done properly
Treatment starts with a proper look: what has failed, what caused it and whether new sealant will actually solve it. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in, with backing rod setting the depth where it’s needed. The enquiries we see most involve patchy repairs in mismatched sealant and occupiers reporting cold air round windows, on balcony and threshold joints, window and door perimeters on blocks and communal entrances and stairwells. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Mowshurst, that means joint design, primers and backing rod as standard.
Owners and agents with buildings around smaller places such as Mowshurst tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.
Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

What else we do in Mowshurst
Should maintenance staff do it?
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Mastic sealing around Mowshurst: points for this area
Mowshurst lies roughly 21 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations, and window and balcony mastic on them tends to age at the same rate. Mowshurst is in the South East, one of the UK’s drier regions. Outside work still depends on dry joints, and south- and west-facing elevations, which take the most sun and rain, often age first.
Older community buildings, Church of St Peter and St Paul among them, often have frames of mixed ages whose mastic varies. Schools and community buildings such as Edenbridge Primary School need frame and external mastic kept sound like any building.
Mowshurst is about 7 miles north-east of East Grinstead, in Kent. Across the TN8 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Our Kent coverage takes in 931 places. For work in that direction, see our London page, about 21 miles away.

Questions we’re asked in Mowshurst
Do you work for managing agents with blocks near Edenbridge station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.
Is a smaller place like Mowshurst outside your area?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.
Can you take on resealing for a block portfolio?
Yes, that’s exactly who this service is for. Buildings are scheduled in turn with dates agreed in advance.
How long before the joints can be used?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
How long do sealant joints last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Can people stay in the building while you reseal?
Occupiers stay in the building throughout. If any flats or units need access, we will tell you in advance so it can be arranged.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Why deal with it now?
Sealing over failed mastic looks tidy for a while. It won’t grip the old sealant and soon comes away. Full removal and proper preparation is what lasts. Around Mowshurst, it’s better to renew all the failing joints at once. Send photos of each area and we will quote for the lot.

After the work
Keep the joints in good shape with a few simple steps:
- Check the asbestos register before any old mastic is disturbed
- Start inspections with the most exposed faces
- Log resealing dates block by block
- Make it easy for occupiers to report draughts
Keep records of when each building was resealed. It helps plan the next round and shows what was done.
One failed perimeter usually means others on the same building are close so a single failure is a sign to check the rest. A planned reseal saves repeated visits.
When to call us in Mowshurst
In communal areas, joints take knocks from bins, bikes, buggies and deliveries, and low-level joints get damaged. Regular cleaning wears them further.
Typical triggers for a call:
- Movement joints with sealant missing
- Water getting in round frames after rain
- Patchy repairs in mismatched sealant
- Mastic failing across several blocks on an estate
Older buildings near Mowshurst, from historic houses such as Hever Castle, 2.3 miles south-east of Mowshurst, to more modest stock, need compatible products when frames are resealed.
