Mastic sealing in Elsted Marsh, done properly
Different joints need different sealants. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, and MS polymer sealants stick well to many substrates and often take paint. We’ll confirm the colours available for the specified product. We work on shopfronts below residential blocks, communal kitchens and washrooms and external wall and movement joints, and the failures we are asked to look at most are open joints in brickwork or panels and brittle perimeter mastic across a building. Most enquiries from Elsted Marsh start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
In and around smaller places like Elsted Marsh, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Looking after the joints
Problems stay small when the joints are checked regularly. In particular:
- Prioritise elevations facing the weather
- Encourage occupiers to report problems at frames
- Check sealant joints during planned building inspections
- Have the asbestos survey to hand for older buildings
Log the date and extent of the resealing for each block. It helps plan the next round and gives you a history.
Mastic fails gradually, then all at once in a wet spell. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.

Planned mastic for Elsted Marsh portfolios
Elsted Marsh lies roughly 47 miles out from central London. Managed blocks of flats are a big part of commuter-belt property, and window and balcony mastic on them tends to age at the same rate. The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, while the elevations that take the most sun tend to show hardened mastic first.
Historic properties like Cowdray House (to the east of Elsted Marsh) show the age of some local stock, where frame mastic must suit soft brick or stone. If you are responsible for a building such as St George's Church, frame and door mastic needs the same attention as any other property.

- Leaks through the frame itself rather than the perimeter
- Materials that need asbestos testing before work
- Misted or failed double-glazed units

When to call us in Elsted Marsh
UV and rain age external sealant. The surface chalks, the body stiffens and cracks appear, especially on south and west faces.
If one of these sounds familiar, it’s time for a closer look:
- A mix of products and colours from past repairs
- Window mastic that has split and shrunk
- Complaints coming in block by block
- Estate-wide sealant that is simply worn out
For owners of several units at places like Midhurst Business Centre, 2.6 miles east of Elsted Marsh, one programme can deal with frame and external mastic across the lot.
Before you book anyone
- Will failed sealant be removed rather than covered?
- Their pre-qualification and accreditations
- What site paperwork they can supply
- How long is the guarantee, and what does it include?
Why act early in Elsted Marsh
Failed perimeter mastic lets cold air in around frames, and they often blame the windows. Resealing the perimeters is often the simpler fix when the frames themselves are sound. Halls, stores and units around places like Elsted Marsh may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
