Mastic sealing in West Kingsdown
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
General trades versus a specialist
Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
Mastic sealing for commercial buildings in West Kingsdown
Owners and agents typically inherit a building’s mastic rather than choose it and it slowly wears out: it sits round windows and doors, along external joints and through communal areas. Once it cracks, hardens or comes away, draughts and water find a way in, and occupiers start reporting it. We work on shopfronts below residential blocks, balcony and threshold joints and communal kitchens and washrooms, and the usual reasons a site gets in touch are no planned programme for sealant and failed external movement joints. A specialist sealant contractor works differently from a general builder: on jobs in West Kingsdown, preparation and product choice get the time they need.
Older buildings and conversions around places like West Kingsdown mix old masonry with newer frames. Perimeter joints need a sealant that suits both frame and masonry.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

West Kingsdown is about 19 miles from central London. Managed blocks of flats are a big part of commuter-belt property, and window and balcony mastic on them tends to age at the same rate. West Kingsdown is in the South East, one of the UK’s drier regions. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building normally need attention first.

Honest limits
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:

- Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
If in doubt, speak to us on 01277 525 020 or send photos by email and we will say what we think.

How a job runs

- Each block or building is walked and the failed joints recorded with the likely cause.
- You get a fixed quote, priced per building where that helps your budgeting.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Failed mastic is removed and the faces taken back to sound, dry material.

Different surfaces, different methods
External movement joints
The joint width has to suit the movement and the sealant’s capability with the width-to-depth ratio set as the manufacturer advises.
Tenement and older buildings
Some old mastics in pre-2000 buildings contain asbestos, so we check the asbestos register or survey first. If it’s suspected, work stops until it’s tested.
