Maintenance after handover
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Plan resealing building by building rather than complaint by complaint
- Reduce knocks to communal area joints
- Have the asbestos survey to hand for older buildings
- Track which buildings were done and when
Include sealant in planned building inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away, and note the building and elevation.
Left open, joint edges in render, brick or frames can deteriorate. Once that happens, repairs come before resealing and the job grows.
Mastic sealing in Shepherd's Bush, done properly
For over 20 years we have resealed joints for owners, agents and landlords. Every applicator holds a CSCS card and we hold public liability insurance. Resealed mastic joints in Shepherd's Bush carry our 12-month guarantee. The enquiries we see most involve no planned programme for sealant and damaged joints in communal entrances and corridors, across communal entrances and stairwells, communal kitchens and washrooms and balcony and threshold joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Shepherd's Bush, that means joint design, primers and backing rod as standard.
London has a large stock of purpose-built blocks, mansion flats and converted buildings managed by agents and housing associations. Window and door perimeters, balcony joints and communal areas all have mastic that ages together across a building, which is why block-wide programmes make sense.
Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

If you look after a block within reach of Shepherds Bush station, which lies north-east of Shepherd's Bush, frame and balcony mastic can be renewed on one programme. Site managers at schools like Addison Primary School can fit frame mastic into the summer works.

- The quote is fixed and split as suits you.
- We agree the programme and dates with you.

Advice
When to bring in a specialist
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Signs you need mastic sealing in Shepherd's Bush
We often find joints filled solid with no backing rod so the mastic is bonded on three sides. It can’t stretch properly and it tears.
It’s worth sending us details if you spot any of the following:
- No planned programme for sealant
- Water getting in round frames after rain
- Draught complaints from residents or tenants
- Cracked, hardened mastic round windows on a block
Older community buildings, Shepherd's Bush Tabernacle among them, often have frames of mixed ages whose mastic varies.
Before you book anyone
- Whether primer will be used where the manufacturer specifies it
- Health and safety accreditation such as CHAS
- Whether their applicators hold CSCS cards
- Their approach to joint depth and backing

Shepherd's Bush: questions and answers
Is Berghem Mews Business Village, near Shepherd's Bush, within your area?
Yes. Our area takes in Shepherd's Bush and its surroundings, with estates and business parks such as Berghem Mews Business Village included. A few photos and the unit address let us price the work.
Can you quote for a block close to Shepherds Bush station?
Yes. Blocks of any size are within what we do. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Can weather delay the job?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
How do you handle work on occupied blocks?
Occupiers stay in the building throughout. If any flats or units need access, we will tell you in advance so you can arrange it with occupiers.
Who decides which product is used?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
