Yes. Estates, retail parks and business parks around Barking, Lyon Business Park among them, are all within reach. To start, just call the office on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

How do you choose the sealant?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Can you send RAMS and CSCS details before starting?
We are CHAS accredited, a Constructionline member and carry public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

Advice
Blocks and managed buildings in Barking
Seven care or nursing homes sit less than 2 miles from Barking. Care home owners need frame and external mastic kept sound without unsettling residents. In London, mastic work on a block goes through the managing agent or landlord, with notice to residents. Our programme follows the access you agree with residents.
For owners of several units at places like Lyon Business Park, less than half a mile south of Barking, one programme can deal with frame and external mastic across the lot. Blocks of flats and mixed-use buildings often cluster around stations such as Barking station, 0.8 miles to the north-west of Barking, and their window and balcony mastic tends to age at the same rate across a building. If your remit includes a building such as Eastbury Primary School, frame and door mastic can be programmed for the holidays.
Barking is about 9 miles east of London, in Greater London. If you’re looking for mastic sealing in Barking, we can help. 764 places across Greater London fall within our area, Barking among them. For work in that direction, see our London page (9 miles or so).

General trades versus a specialist
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Aftercare for building managers
A few simple habits keep the new joints working:
- Share your contractor requirements early
- Check sealant joints during planned building inspections
- Keep a record of when each building was resealed
- Have the asbestos survey to hand for older buildings
Add mastic joints to your cyclical inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away, and note the building and elevation.
Planned resealing is easier to budget than emergency repairs. We can quote buildings in priority order so spending is spread.
What sealant work can’t fix
Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:
- Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
- Misted or failed double-glazed units
- Failed window or door frames, which need a window contractor
If in doubt, phone 01277 525 020 or use the quote form and we will say what we think.

Different surfaces, different methods
Tenement and older buildings
Traditional buildings have joints that need a careful approach. The material either side of the joint shapes the product choice.
Commercial and mixed-use buildings
Where retail and residential share a building, so phasing has to suit both. Tell us your site hours and access windows and we will plan around them.
Building owners, agents and FMs in Barking
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Barking can sit alongside others in a wider programme across Greater London.
