About our mastic sealing in Kingston
Across Kingston and the rest of Kent, we work the same way: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. Addresses, photographs of typical joints and a rough idea of quantities let us give a quick quote or we can visit. Site teams most often ask us about communal area joints that look neglected and repeated reactive repairs to the same buildings, on balcony and threshold joints, communal kitchens and washrooms and shopfronts below residential blocks. A specialist sealant contractor works differently from a general builder: in Kingston, that means joint design, primers and backing rod as standard.
For buildings around smaller places like Kingston, we group work so one trip covers it. Photos of each elevation help us quote accurately.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Mastic sealing in Kingston: the local picture
At about 57 miles from central London, Kingston is within reach of the capital. Within reach of London, blocks run by agents and associations are common around stations; their frame mastic often ages block-wide. The South East is one of the drier parts of the UK. External mastic still waits for dry faces and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.
For agents with blocks near Adisham station, 2.7 miles north-east of Kingston, a block-wide mastic programme deals with frames, balconies and entrances in one go. Churches, halls and community buildings such as Church of St Giles are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.
Kingston is about 5 miles south-east of Canterbury, in Kent. Our applicators travel to Kingston for work on mastic joints. Kingston is one of 931 places we cover in Kent. Sites around London have their own page, about 57 miles away.

Our process
We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. For work around Kingston, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.
- We inspect the joints, building by building, and record what has failed and why.
- A fixed quote follows, split by block or building if that suits you.
- 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.
- Each building is checked on completion and the work carries our 12-month guarantee.

When it isn’t the sealant
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Leaks through the frame itself rather than the perimeter
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
If in doubt, call 01277 525 020 or email drawings and photos and we’ll say what we think before you book.
Surfaces we seal
- Shopfronts below residential blocks
- Balcony and threshold joints
- Communal kitchens and washrooms
- Window and door perimeters on blocks
- External wall and movement joints
- Communal entrances and stairwells
Surface by surface
Communal areas
Communal areas stay in use while we work. We work in sections so access is never blocked.
External movement joints
Failed sealant is removed, backing rod inserted to control depth and the joint resealed with a grade whose movement class fits.
Questions about Kingston
Do you work for managing agents with blocks near Adisham station?
Yes. Blocks of any size are within what we do. Send the address, photographs of the elevations and your access arrangements, and we’ll give a fixed quote.
Is Kingston off your patch?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Who decides which product is used?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Does the weather affect the work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Is mastic sealing guaranteed?
There is a 12-month guarantee on our workmanship and we hold public liability insurance.
Do you work with property factors and landlords?
Yes. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords, and we quote building by building or as a programme.
Site staff or a sealant specialist?
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Looking after the joints
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- List the paperwork your organisation requires when you send details
- Keep a record of when each building was resealed
- Check sealant joints during planned building inspections
- Start inspections with the most exposed faces
Keep records of when each building was resealed. It helps plan the next round and shows what was done.
Leaks at window perimeters spoil finishes and can affect frames. Resealing early keeps the job small.
Common problems we fix in Kingston
Sunlight and weather break mastic down over time. It stiffens, stops stretching and cracks, especially on south and west faces.
What tends to prompt an enquiry:
- Open joints in brickwork or panels
- The same joint failures repeated across a portfolio
- Worn sealant at communal door frames
- Occupiers reporting cold air round windows
Student accommodation around universities such as University for the Creative Arts, 4.6 miles north-west of Kingston, is usually managed block by block, which suits a planned mastic programme.
