Mastic sealing in Southerness, done properly
Older blocks and commercial buildings can have mastic that contains asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. We don’t remove asbestos-containing materials. If you’re dealing with brittle perimeter mastic across a building and water getting in round frames after rain, we can help, whatever the surface. A specialist sealant contractor works differently from a general builder: in Southerness, that means joint design, primers and backing rod as standard.
For buildings around Southerness, we group the work to keep travel and visits down. Send addresses and photographs for a quote covering the batch.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Diagnose, treat, sign off
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Jobs near Southerness are often grouped with others in the same area, to make the most of each trip. Tell us how flexible your dates are.

Common problems we fix in Southerness
Occasionally the substrate fails, not the sealant for instance where render or brick edges crumble. If the edges are unsound, we say so before quoting the sealing.
These are often picked up first by site or facilities staff:
- Complaints coming in block by block
- Brittle perimeter mastic across a building
- Mastic failing across several blocks on an estate
- Patchy repairs in mismatched sealant
Around Southerness, a planned programme renews failed mastic across a building or estate in one go.

FAQs: Southerness
Is Southerness off your patch?
Not at all: smaller places are covered as well as towns. We cover the whole of Scotland. We plan jobs in smaller places so return trips are kept to a minimum.
Do you take on block-wide or estate-wide mastic work in Southerness?
Yes. Planned programmes across a building, block or estate are a core part of this service. Send the addresses and photographs and we’ll give a fixed quote.
What about access for upper-floor joints?
We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned, and we’ll tell you how we’d approach it.
Can you take on resealing for a block portfolio?
We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work, and we quote building by building or as a programme.
Does the weather affect the work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
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 supply RAMS and insurance details?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We hold CHAS accreditation and Constructionline membership.
After the work
A few simple habits keep the new joints working:
- Make mastic part of routine maintenance checks
- Ask residents or tenants to report leaks and draughts early
- List the paperwork your organisation requires when you send details
- Plan resealing building by building rather than complaint by complaint
Log the date and extent of the resealing for each block. That makes future programmes easier to plan and gives you a history.
The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing.
Leave it or put it right?
Mixed repairs by different contractors leave a patchwork of products and colours. A block-wide reseal gives one product, one colour and one guarantee and one 12-month guarantee. For buildings near Southerness, dealing with all the failing joints at once saves return trips. Photos of each area help us quote the whole job.
The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.

Mastic sealing around Southerness: how the place shapes the job
Southerness lies within about 1 mile of the sea. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do. The east of Scotland, where Southerness is, gets less rain than the west. Frost and condensation on winter mornings can still delay outside mastic. We plan block programmes with some give for it
Near Southerness, we review each elevation first so the quote covers what actually needs doing.
