How we handle mastic sealing in Blackness
On a residential block, the work happens around people’s lives. Dates, areas and the order of work are agreed with you in advance, giving you what you need to notify residents. Communal entrances and stairs stay usable while we work. We work on external wall and movement joints, shopfronts below residential blocks and communal kitchens and washrooms, and the usual reasons a site gets in touch are failed external movement joints and communal area joints that look neglected. A single leaking joint is often how a building in Blackness first comes to us: we look at the rest while we’re there and tell you what we find.
Owners and agents with buildings around smaller places such as Blackness tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, give us a call on 01277 525 020 or email us and we will come back to it.

Keeping the joints sound
Problems stay small when the joints are checked regularly. Specifically:
- Check the asbestos register before any old mastic is disturbed
- Keep a record of when each building was resealed
- Group repairs into a planned programme
- Ask residents or tenants to report leaks and draughts early
Where a paintable product was specified, it can be painted after curing. Silicone typically can’t be painted, so keep decorators off it.
Failed mastic often goes unnoticed until heavy rain finds it. Resealing when cracking first shows avoids water damage and the complaints that come with it.
Quoting for work in Blackness
There’s no standard rate for sealant work, because every site is different. What we take into account:
- Travel to remote or island sites
- Phasing around occupants
- The product specified
- Whether old sealant has to be cut out first
The product called for affects the cost, and so does the preparation. Access, phasing and site requirements come into it too.
Details that help us quote
A good diagnosis starts with the right details. Tell us:
- The site address and postcode
- Any dates the work must fit around
- Photos of the joints, close up and from further back
- How the joints are reached, and at what height
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to call the office on 01277 525 020 or email us with what you know.
Common questions from Blackness clients
Can work in a care setting near Blackness go ahead while residents are there?
Yes. We work around residents’ routines, a room or two at a time. Any site rules, from signing in to infection control, are agreed before we start.
We manage a building near Pevensey & Westham station. Can you help?
Yes. Blocks of any size are within what we do. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
What about access for upper-floor joints?
It depends on the building. We agree access with you at quote stage so there are no surprises.
Do you check for asbestos in old sealant?
Some mastics in pre-2000 buildings contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.
Will you just go over the old sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
How long does a typical visit take?
It depends on the scope, though a typical visit usually takes a few days for most blocks, with larger programmes scheduled building by building. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it.
What sealant work can’t fix
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:
- Glazing that needs replacing
- Masonry that has broken away beside the joint
- Roof leaks, gutters or failed flashings that aren’t sealant joints
If in doubt, phone 01277 525 020 or send details through our quote form and we will say what we think before you book.

Planned maintenance
Adding mastic to planned maintenance avoids reactive repairs and spreads the work.
Mastic sealing around Blackness: points for this area
With the shore within about 3 miles, Blackness counts as a coastal location. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do. The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building normally need attention first.
Property owners at sites such as Langsett Industrial Estate, 0.6 miles to the south-east of Blackness, can have mastic renewed between lettings. For a school such as Stone Cross School, perimeter mastic on windows and doors is a holiday job.
Blackness is about 2 miles north of Eastbourne, in East Sussex. We cover commercial sites throughout Blackness, for single jobs and planned programmes alike. Blackness is one of 308 places we cover in East Sussex for mastic joints. Brighton is covered too, some 18 miles away.
