Mastic sealing for commercial buildings in Broad Green
In buildings from before 2000, some old mastics contain 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. If you have damp patches beside frames and a mix of products and colours from past repairs, we can help, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, in Broad Green it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
For managing agents in Broad Green, resident access, notice periods and the building’s rules shape the job. We work to the agent’s notice and access plan, so residents know what’s happening.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Frames, entrances and external joints in Broad Green
Broad Green has five care or nursing homes no more than 2 miles away. Frame mastic on care buildings is best renewed elevation by elevation, with the manager deciding timings. For a London block, the agent or landlord usually handles notices to residents and access to flats. Our programme follows the access you agree with residents.
Landlords with units on estates such as Pilton Industrial Estate, 0.7 miles south of Broad Green, can bring frame, door and external mastic across several units into one programme. If your remit includes a building such as Elmwood Infant School, frame and door mastic can be programmed for the holidays.
Broad Green is about 6 miles south of Stockwell, in Greater London. Commercial clients in Broad Green can call on us for mastic joints. Broad Green is one of 764 places in Greater London on our list for mastic joints. Our London page has more on work in that area.
If you need mastic sealing in CR0, CR7 and CR90, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. If your site is on York Road, Nova Road and Lion Road or close by, we can quote for mastic joints. Just outside Broad Green, we also work in Old Town (1 mile south), Beddington (2 miles south-west), Waddon (2 miles south), Bandonhill (2 miles south-west) and Wallington (2 miles south-west). Bigger towns within reach include London (8 miles north), City of Westminster (9 miles north), Marylebone (9 miles north), Kensington (9 miles north-west), St Pancras (10 miles north) and Shoreditch (10 miles north).
Around Broad Green
We work on buildings around Harris Invictus Academy Croydon, The Half Moon pub and Waddon Ponds and the streets around them. The nearest railway station is West Croydon station, roughly 0.6 miles south. A little further out are Centrale Croydon (0.8 miles south) and Croydon University Hospital (less than half a mile north-west). Not far away are Duppas Hill and Biggin Wood.
What we are called out for in Broad Green
Topping up old mastic is a common shortcut. New sealant won’t grip failed sealant, so these repairs rarely last.
Typical triggers for a call:
- Occupiers reporting cold air round windows
- Leaks at window and door perimeters
- Damaged joints in communal entrances and corridors
- Open joints in brickwork or panels
Churches, halls and community buildings such as Church of St Saviour are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.
Questions to ask before you book
- Whether old or failed sealant will be cut out, not overlaid
- Their approach to joint depth and backing
- The terms of the workmanship guarantee
- Health and safety accreditation such as CHAS
When something else is needed
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Asbestos-containing sealant, which we don’t remove
- Failed window or door frames, which need a window contractor
- Broken glass or failed sealed units
Not sure which it is? You can ring 01277 525 020 or send photos by email and we will tell you honestly before you book.
Where we work in Broad Green
- Window and door perimeters on blocks
- External wall and movement joints

- Communal entrances and stairwells
Broad Green: questions and answers
Can you cope with the access rules in a London building?
Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry. We allow for the ULEZ, which covers every borough
Can you work at a site such as Pilton Industrial Estate, by Broad Green?
Yes, sites like Pilton Industrial Estate are within our area, along with the rest of Broad Green. Send details of the unit and the work through our quote form for a quick quote.
What about access for upper-floor joints?
Access is discussed and agreed before the quote is fixed. Tell us the number of storeys and whether scaffold or other access is planned and we will confirm the approach in the quote.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Is asbestos a concern with old mastic?
We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.
Can you quote from photos?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day.
Commercial clients in Broad Green
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
We work for building owners and managing agents on everything from one building to a spread of sites around Broad Green. Several sites can go on one quote, which keeps the paperwork simple.

After the work
Keep the joints in good shape with a few simple steps:
- Make it easy for occupiers to report draughts
- Check the asbestos register before any old mastic is disturbed
- Share your contractor requirements early
- Avoid piecemeal callouts where you can
Keep bins, bikes and deliveries away from low-level joints where you can. Damage at low level is the most common reason communal joints fail early.
Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings so spending is spread.
Different surfaces, different methods
Estate-wide resealing programmes
Using the same products throughout keeps the estate consistent.
Tenement and older buildings
Stone needs a neutral-cure product, so we pick a grade that won’t mark it.
