Mastic sealing in South Ealing, done properly
Older blocks and commercial buildings can have mastic that contains asbestos. Before we disturb it, we ask to see the asbestos register or survey and if it’s suspected, work stops until it’s tested. Removing asbestos-containing material isn’t something we do. We work on external wall and movement joints, communal kitchens and washrooms and shopfronts below residential blocks, and the usual reasons a site gets in touch are window mastic that has split and shrunk and open joints in brickwork or panels. Looking for mastic applicators who cover South Ealing? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
For managing agents in South Ealing, resident access, notice periods and the building’s rules shape the job. Work is planned with the agent so residents get notice and access is arranged in advance.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Common questions from South Ealing clients
Can you cope with the access rules in a London building?
Yes, most London buildings have access rules of some kind, and we plan around them. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly.
Is Phoenix Trading Estate, near South Ealing, within your area?
Yes, sites like Phoenix Trading Estate are within our area, along with the rest of South Ealing. To start, just ring 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Can you send RAMS and CSCS details before starting?
Our credentials include CHAS, Constructionline and public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Can you quote from photos?
It depends on the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.
How do you choose the sealant?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
How many days will you need on site?
That varies with the scale of the job, though a typical visit usually takes a few days for most blocks, with larger programmes scheduled building by building. For bigger or phased jobs, we’ll set out a timescale with the quote.

Why act early in South Ealing
Mixed repairs by different contractors leave a patchwork of products and colours. Resealing a whole building gives a consistent finish. In South Ealing, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
Pricing mastic joints depends on quantities, condition and access, plus any specification you’re working to. Call for a quote.

Maintenance after handover
Cleaning and maintenance staff play a part too. Share these points with them:
- Plan resealing building by building rather than complaint by complaint
- Check the asbestos register before any old mastic is disturbed
- Prioritise elevations facing the weather
- Log resealing dates block by block
Ask residents or tenants to report draughts or leaks round windows early. A quick report keeps a small repair small.
One failed perimeter normally means others on the same building are close so a single failure is a sign to check the rest. Doing them together saves going back again and again.
Surface by surface
External movement joints
Movement joints are cleaned out, backed with rod and resealed with a sealant of the right movement class.
Commercial and mixed-use buildings
Where retail and residential share a building the programme has to suit everyone. Tell us your site hours and access windows and we’ll plan around them.
What we can’t put right
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Frames that are rotten, warped or broken
- Substrate edges that need repairing first
- Asbestos-containing sealant, which we don’t remove
If you are not sure, just speak to us on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.

For owners and agents in South Ealing
In London, mastic work on a block goes through the managing agent or landlord, with notice to residents. We fit the programme to your notice periods.
Blocks of flats and mixed-use buildings often cluster around stations such as Brentford station (0.9 miles south of South Ealing) and their window and balcony mastic tends to age at the same rate across a building. Churches, halls and community buildings such as St Mary's Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Student accommodation around universities such as The University of West London, under half a mile north of South Ealing, is normally managed block by block, which suits a planned mastic programme.

Should maintenance staff do it?
Site maintenance staff can often handle a short internal joint. 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.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
