About our mastic sealing in Denstroude
Most buildings come with mastic joints nobody has looked at since handover, and it ages quietly: window perimeters, door frames, external joints and communal junctions all rely on it. Once it cracks, hardens or comes away, draughts and water find a way in, and occupiers start reporting it. If you are dealing with draughts at frames across a block and the same joint failures repeated across a portfolio, we can put it right, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Denstroude is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In and around smaller places like Denstroude, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Common problems we fix in Denstroude
Sunlight and weather break mastic down over time. It stiffens, stops stretching and cracks, especially on south and west faces.
Clients typically get in touch after noticing something like this:
- Leaks at window and door perimeters
- A mix of products and colours from past repairs
- Brittle perimeter mastic across a building
- Draughts at frames across a block
If you look after a block within reach of Whitstable station (3 miles north of Denstroude), frame and balcony mastic can be renewed on one programme.

Advice
Work for main contractors and building owners
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.
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.

What sealant work can’t fix
Before quoting, we check that sealant is the right answer. It won’t put right:
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Substrate edges that need repairing first
- Leaks through the frame itself rather than the perimeter
Not sure which it is? You can call 01277 525 020 or use the quote form and we’ll tell you honestly.

Questions about Denstroude
Our building in Denstroude is near the coast: does that change the sealant?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We check the specified product suits the exposure and pay close attention to preparation.
Do you cover business parks and estates near Denstroude, such as John Roberts Business Park?
Yes. Estates, retail parks and business parks around Denstroude, John Roberts Business Park among them, are all within reach. To start, just phone 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.
Will you come and look before quoting?
Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we will arrange a visit.
How soon can the area be used again?
We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
What will the job cost?
We don’t publish prices, as every site differs. Send photographs or drawings and we’ll price it at a fixed figure.
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.
Does the weather affect the work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Site staff or a sealant specialist?
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
