When it isn’t the sealant
Honesty saves time and money. New sealant won’t cure:
- Masonry that has broken away beside the joint
- Misted or failed double-glazed units
- Materials that need asbestos testing before work
If in doubt, call 01277 525 020 or email drawings and photos and we will say what we think.
What we seal
- External wall and movement joints
- Balcony and threshold joints
- Shopfronts below residential blocks

- Window and door perimeters on blocks
- Communal entrances and stairwells
Mastic sealing in Langton Green, done properly
Blocks are lived in, so access and disruption have to be thought through. The sequence, the areas and the dates are settled with you so you can let residents know what is happening. Entrances and stairwells are kept in use while we work. Site teams most often ask us about movement joints with sealant missing and leaks at window and door perimeters, across communal entrances and stairwells, balcony and threshold joints and window and door perimeters on blocks. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Langton Green is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Converted and older buildings in and around Langton Green often put modern windows into old walls. The mastic there needs to suit both surfaces.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Frames, entrances and external joints in Langton Green
Langton Green is about 29 miles from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres. The South East is one of the drier parts of the UK. Outside work still depends on dry joints, while the elevations that take the most sun tend to show hardened mastic first.
Buildings close to stations like Tunbridge Wells station, 2.1 miles to the east of Langton Green, are often flats over shops, with frame mastic to keep sound. Schools and community buildings such as Langton Green Primary School need frame and external mastic kept sound like any building.
Langton Green is about 2 miles west of Royal Tunbridge Wells, in Kent. Across the TN3 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Langton Green is one of 931 places we cover in Kent for mastic joints. Sites around Brighton have their own page, about 26 miles away.

What the job involves on each surface
Communal areas
Joints at low level in communal areas take knocks from bins, bikes and buggies, so they often need renewing sooner.
Tenement and older buildings
Older buildings, including Scotland’s sandstone tenements, have their own joint details. We look at the substrate before choosing a sealant.
Signs you need mastic sealing in Langton Green
Sunlight and weather break mastic down over time. It stiffens, stops stretching and cracks, especially on south and west faces.
Any of the following is a good reason to get the joints checked over:
- Damaged joints in communal entrances and corridors
- Open joints in brickwork or panels
- Complaints coming in block by block
- The same joint failures repeated across a portfolio
Student accommodation around universities such as Canterbury Christ Church University - Salomons, 1.8 miles to the north-east of Langton Green, is usually managed block by block, which suits a planned mastic programme.
What to look for in a quote
- Is the sealant right for the movement and the substrate?
- Whether primer will be used where the manufacturer specifies it
- How the existing material will be dealt with
- How they’ll work around occupants
Should maintenance staff do it?
Putting right a botched joint often costs more than sealing it well at the start, 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 brings efficiency, a consistent finish and a 12-month guarantee.
Langton Green: questions and answers
Does your area include sites such as Speldhurst Business Park, near Langton Green?
Yes. Our area takes in Langton Green and its surroundings, with estates and business parks such as Speldhurst Business Park included. To start, just call the office on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Is Langton Green too far out for you?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can people stay in the building while you reseal?
Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so it can be arranged.
Will you come and look before quoting?
That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
What will the job cost?
Every job gets its own fixed quote. For yours, ring 01277 525 020 or email drawings and photos with a description of the work.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Looking after the joints
A few simple habits keep the new joints working:
- Group repairs into a planned programme
- List the paperwork your organisation requires when you send details
- Log resealing dates block by block
- Reduce knocks to communal area joints
Ask residents or tenants to report draughts or leaks round windows early. Early reports catch failures before damage spreads.
The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing.
