Mastic sealing in Brasted
In buildings from before 2000, some old mastics contain asbestos. Before we disturb it, we ask to see the asbestos register or survey, and work stops for testing if there’s any doubt. Removing asbestos-containing material isn’t something we do. If you have estate-wide sealant that is simply worn out and old repairs sealed over failed mastic, we can put it right, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Brasted it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Rural conversions near places like Brasted often set modern frames into older stone, flint or brick. Perimeter mastic there has to grip an uneven face and suit the building’s character.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

How the quote is worked out
Each job is priced on its own details. The main factors are:
- Whether old sealant has to be cut out first
- Specialist products, such as fire-rated or hygienic sealants
- Working within restricted access windows
- The size and state of each joint
The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
Before you send an enquiry
We can often quote from photos and a few details. It helps to include:
- Drawings or a marked-up plan, if available
- Anything awkward about access or site hours
- The product your specification calls for
- Asbestos survey details if the building is older
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.
Our process
We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Smaller jobs around Brasted can be grouped with others nearby. You’ll have a fixed quote before work starts.
- First we look at the mastic on each building and note what needs replacing.
- A fixed quote follows, split by block or building if that suits you.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Before we start on site
- Tell us which areas need to stay in use
- Let building users know which areas are affected
- Have the specification and drawings to hand
Getting a fixed quote
Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.
Advice
How the job changes by surface
Tenement and older buildings
Some old mastics in pre-2000 buildings contain asbestos, so we check the asbestos register or survey first. Suspect material is tested before work continues.
Communal areas
Low-level communal joints get damaged more than most and tend to fail first.
Why deal with it now?
A bead run over old mastic can look like a repair. It doesn’t bond and normally fails within a short time. Cutting out and resealing properly does it once. Converted and older buildings near places like Brasted tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
There’s no price list, because the scope varies so much from one building to the next. Call for a quote.
Why us?
- Failed material removed, not covered up
- Colour options checked against the specified product

Questions about Brasted
Do you work for managing agents with blocks near Dunton Green station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.
Is Brasted too far out for you?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
When can the area be used after sealing?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.
Who decides which product is used?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Can you plan resealing across several buildings?
We can. We survey and price each building, then work through them in order starting wherever is most urgent.
How long does a job like this take?
It depends on the scope, though a typical visit typically takes one or more days per building, depending on the joint lengths and the access. For bigger or phased jobs, we will set out a timescale with the quote.
What guarantee do you give on resealing?
A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.

Block-wide mastic in Brasted
The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first. Brasted is about 18 miles from central London. Managed blocks of flats are a big part of commuter-belt property.
Site managers at schools like Combe Bank School can fit frame mastic into the summer works. Blocks of flats and mixed-use buildings often cluster around stations such as Dunton Green station (to the north-east of Brasted) and their window and balcony mastic tends to age at the same rate across a building.
Brasted is about 3 miles west of Sevenoaks, in Kent. Businesses, contractors and managing agents in Brasted can call on us for mastic joints. 931 places across Kent fall within our area, including Brasted. There’s a separate page for London, roughly 18 miles from Brasted.

Well-known places in the area include Sevenoaks Museum (3.8 miles east) and Tandridge Priory (3.8 miles south-west). Green spaces nearby include Betsom's Hill and Dryhill Nature Reserve.
Looking after the joints
Cleaning and maintenance staff play a part too. Share these points with them:
- Keep a record of when each building was resealed
- Plan resealing building by building rather than complaint by complaint
- Have the asbestos survey to hand for older buildings
- Keep bins and bikes away from communal door frames
Encourage occupiers to report water or draughts at frames. A quick report keeps a small repair small.
Budgets are easier to plan when sealant is part of planned maintenance. We can quote buildings in priority order so spending is spread.
What we are called out for in Brasted
Buildings move with temperature and moisture, and every joint has to stretch and squeeze with them. If the joint or the product wasn’t suited to the movement, it splits long before it should.
What tends to prompt an enquiry:
- Patchy repairs in mismatched sealant
- Repeated reactive repairs to the same buildings
- Damaged joints in communal entrances and corridors
- Window mastic that has split and shrunk
Landlords with units on estates such as Salters Heath Business Centre, 2.4 miles to the east of Brasted, can bring frame, door and external mastic across several units into one programme.
Questions to ask before you book
- How the joint faces will be prepared and primed
- How they handle RAMS and site documents
- The named product and why it was chosen
- Will CSCS-carded applicators be on site?
