What we are called out for in Wishanger Common
In communal areas, joints take knocks from bins, bikes, buggies and deliveries, and low-level joints get damaged. Cleaning products add to the wear.
Most enquiries start with one or more of the following:
- Cracked, hardened mastic round windows on a block
- Draughts at frames across a block
- Damp patches beside frames
- Open joints in brickwork or panels
If you manage student housing near a university such as University for the Creative Arts, which lies north of Wishanger Common, the summer turnaround is the time for mastic.

Mastic sealing for commercial buildings in Wishanger Common
Different joints need different sealants. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, while hybrid polymer sealants grip many materials and are often paintable, and colours are confirmed for whichever product is used. The enquiries we see most involve damaged joints in communal entrances and corridors and complaints coming in block by block, on communal entrances and stairwells, communal kitchens and washrooms and balcony and threshold joints.

Common questions from Wishanger Common clients
Do you work for managing agents with blocks near Bentley (Hampshire) station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Photos of each elevation help us quote accurately.
Will you price a mastic programme across our Wishanger Common portfolio?
Yes. Portfolio-wide programmes are a regular request. Residents are given notice through you, and the work moves building by building.
Can people stay in the building while you reseal?
Residents and tenants carry on as normal. We flag any areas that need internal access well before the dates so you can arrange it with occupiers.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Is mastic sealing guaranteed?
Our workmanship carries a 12-month guarantee, backed by public liability insurance.
Do you cover Wishanger Common?
Yes. Sites across Wishanger Common are covered, with one number for every area we cover.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
How the job changes by surface
Planned maintenance
We can work into your cyclical maintenance plan, building by building.
Communal areas
We keep entrances and stairs open throughout. Work is planned in sections.
General trades versus a specialist
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
Mastic sealing in Wishanger Common: the local picture
Rainfall across the South East, Wishanger Common included, is lower than in many parts of the UK. Outside work still depends on dry joints, and south- and west-facing elevations, which take the most sun and rain, often age first. Wishanger Common is about 39 miles from central London. Managed blocks of flats are a big part of commuter-belt property.
Trustees of buildings like St John the Evangelist can bring frame and external mastic into a planned maintenance list. Blocks of flats and mixed-use buildings often cluster around stations such as Bentley (Hampshire) station (to the north-west of Wishanger Common) and their window and balcony mastic tends to age at the same rate across a building.

What we can’t put right
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:
- Leaks through the frame itself rather than the perimeter
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Glazing that needs replacing

Aftercare for building managers
A few simple habits keep the new joints working:
- Look at the sunniest and most exposed elevations first
- Check the asbestos register before any old mastic is disturbed
- Protect low-level joints in entrances
- Avoid piecemeal callouts where you can
Include sealant in planned building inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away and record where they are.
Water getting in round frames can damage plaster, decoration and the frames themselves. Resealing early keeps the job small.
