Block-wide mastic in Foxbury
Foxbury has 16 care or nursing homes no more than 2 miles away. Care home owners need frame and external mastic kept sound without unsettling residents. London blocks come with residents to inform, access to agree and often a concierge or estate office to work with. We plan around the notices and access you arrange.
For owners of several units at places like Crayfields Business Park, which lies south-east of Foxbury, 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 Sidcup station (to the north-east of Foxbury) and their window and balcony mastic tends to age at the same rate across a building. Owners of student blocks near University of Greenwich Avery Hill Campus, 1.9 miles north of Foxbury, can schedule frame and external mastic for the summer vacation.
Foxbury is about 1 mile east of Chislehurst, in Greater London. Commercial clients in Foxbury use us for work on mastic joints. Foxbury is one of 764 places in Greater London on our list. London is covered too, around 10 miles from Foxbury.

Mastic sealing in Foxbury
Across Foxbury and the rest of Greater London, we work the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Addresses, photographs of typical joints and a rough idea of quantities let us give a quick quote or we can visit. If you have brittle perimeter mastic across a building and a mix of products and colours from past repairs, we can put it right. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Foxbury it comes down to the same thing: the right product in a properly prepared joint.
For managing agents in Foxbury, 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.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

Our process
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. All of Greater London is in the ULEZ, and kerbside space in Foxbury can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- First we look at the mastic on each building and note what needs replacing.
- We send a fixed quote that sets out the joints, the products and the programme.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Getting the site ready
- Clear stock, furniture or equipment away from the joints
- Send any specification or drawings in advance
- Tell us what induction or permit system the site runs

Using the same products throughout keeps the estate consistent.
External movement joints
External movement joints take up expansion and contraction. Failed sealant in a movement joint lets water in.
Quoting for work in Foxbury
A fixed quote reflects the actual work. It takes account of:
- Site requirements such as inductions and permits
- Any access equipment needed
- Specialist products, such as fire-rated or hygienic sealants
- How much existing material needs removing
A quote for mastic joints depends on quantities, condition and access, plus any specification you’re working to. Call for a quote.
Sending details for a quote
However big the job, the same details help:
- Access details, including height
- The product your specification calls for
- The postcode of the building
- Asbestos survey details if the building is older
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, ring 01277 525 020 or send details through our quote form.
Should maintenance staff do it?
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: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
Common questions from Foxbury clients
Can you quote for a block close to Sidcup 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 cope with the access rules in a London building?
Yes. Inductions, permits and timed loading are routine for us in London. The building manager’s rules go straight into our method. The ULEZ covers the whole of Greater London, which we allow for
What about access for upper-floor joints?
It depends on the building. We agree access with you at quote stage so there are no surprises.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Do you guarantee the mastic work?
Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.
Do you work with property factors and landlords?
We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work and work can be quoted per building or as a whole.
How soon can the area be used again?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
