Mastic sealing for commercial buildings in Upperton
We diagnose before we prescribe: what has failed, what caused it and whether new sealant will actually solve it. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in, with backing rod setting the depth where it’s needed. If you have window mastic that has split and shrunk and worn sealant at communal door frames, we can help. For commercial sealant work in Upperton, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
For landlords and associations with stock in and around Upperton, grouping buildings into one visit saves travel. Send the addresses and photographs and we will quote for all of them together.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

For managing agents and facilities managers
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first.
Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
When it isn’t the sealant
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Broken glass or failed sealed units
- Masonry that has broken away beside the joint
- Leaks through the frame itself rather than the perimeter
If you’re not sure, just ring 01277 525 020 or send photos by email and we will give you a straight answer.
Surfaces we seal
- Window and door perimeters on blocks
- Communal kitchens and washrooms
- External wall and movement joints
- Shopfronts below residential blocks
- Balcony and threshold joints
- Communal entrances and stairwells

What we are called out for in Upperton
In communal areas, joints take knocks from bins, bikes, buggies and deliveries, and low-level joints get damaged. Regular cleaning wears them further.
Look out for the following:
- No planned programme for sealant
- Movement joints with sealant missing
- Mastic failing across several blocks on an estate
- Old repairs sealed over failed mastic
Site managers at schools like St Thomas A Becket Catholic Primary School can fit frame mastic into the summer works.

On site: what to expect
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work normally takes a day or two for a single block, longer for an estate programme. What matters most for a job in Upperton is a clear list of what needs doing. You’ll then get a fixed price for the work.
- First comes a look at the joints and, for older buildings, the asbestos records.
- A fixed quote covers the joints, products and order of work.
- Failed mastic is removed completely.
- Joint faces are cleaned, backed and resealed.
- Buildings are completed in turn.
Before we start on site

Advice
Maintenance after handover
Cleaning and maintenance staff play a part too. Pass these on to them:
- Track which buildings were done and when
- Encourage occupiers to report problems at frames
- Mention RAMS, insurance or CSCS requirements up front
- Look at the sunniest and most exposed elevations first
Our workmanship is covered for 12 months, so report any failure in that time. Beyond that, routine checks spot the next round of repairs.
The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing and the job grows.
Planned mastic for Upperton portfolios
Upperton is within about 1 mile of the coast. On buildings near the shore, the side facing the weather typically needs its mastic renewed first, so it’s worth inspecting those sides more often. The South East is one of the drier parts of the UK. Outside mastic still needs a dry joint and the right temperature, while the elevations that take the most sun tend to show hardened mastic first.
Buildings close to stations like Eastbourne station, less than half a mile to the south-east of Upperton, are often flats over shops, with frame mastic to keep sound. Trustees of buildings like Church of St Mary can bring frame and external mastic into a planned maintenance list.

Upperton: questions and answers
Is Upperton off your patch?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Our building in Upperton is near the coast: does that change the sealant?
It can. Coastal exposure works external joints harder than inland weather. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Can you plan resealing across several buildings?
Block-wide and estate programmes are common. The quote can be split however suits your budgeting.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
Do you check for asbestos in old sealant?
Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.
Different surfaces, different methods
Planned maintenance
We can work into your cyclical maintenance plan on a timetable you set.
Tenement and older buildings
Traditional buildings have joints that need a careful approach. The material either side of the joint shapes the product choice.
