Block-wide mastic in Thong
The sea is no more than about 3 miles from Thong. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do; plan inspections around that. Thong is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.
Schools and community buildings such as Riverview Infant School need frame and external mastic kept sound like any building. Older buildings near Thong, from historic houses such as Cobham College, 1.5 miles to the south of Thong, to more modest stock, need compatible products when frames are resealed. Buildings close to stations like Sole Street station (to the south-west of Thong) are often flats over shops, with frame mastic to keep sound.

Mastic sealing for commercial buildings in Thong
Treatment starts with a proper look: what has failed, what caused it and whether new sealant will actually solve it. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed, with backing rod setting the depth where it’s needed. Site teams most often ask us about the same joint failures repeated across a portfolio and repeated reactive repairs to the same buildings, on communal kitchens and washrooms, external wall and movement joints and shopfronts below residential blocks. For commercial sealant work in Thong, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
For owners with a single building near Thong, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Surface by surface
Window and door perimeters on blocks
On most blocks, the frame-to-wall joint is where failure shows first. We remove the failed mastic, prepare the faces, add backing rod if the joint is deep and reseal.
Commercial and mixed-use buildings
Tenants in commercial buildings need to keep trading, so we plan around them.
Work for main contractors and building owners
If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
Questions about Thong
Will you take on a block within reach of Sole Street station?
Yes, and several blocks can go on one quote. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
Is Thong too small for you to travel to?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photos 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.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
How long do sealant joints last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Can you plan resealing across several buildings?
Yes. 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?
We plan the time on site around your programme and access. You will have an expected duration with the quote.
Aftercare for building managers
Your facilities or cleaning team can help the joints last. Share these points with them:
- Share your contractor requirements early
- Prioritise elevations facing the weather
- Check sealant joints during planned building inspections
- Plan resealing building by building rather than complaint by complaint
If a joint we sealed fails within 12 months, tell us and we’ll look at it. Beyond that, routine checks spot the next round of repairs.
Budgets are easier to plan when sealant is part of planned maintenance. We can quote buildings in priority order and work down the list.
What sealant work can’t fix
We check first that sealant really is the fix. It won’t put right:
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Masonry that has broken away beside the joint
- Water coming in from the roof or rainwater goods
If in doubt, call 01277 525 020 or use the quote form and we will say what we think before you book.

When to bring in a specialist
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear.
