Site staff or a sealant specialist?
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
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.
Mastic sealing for commercial buildings in Clouston
Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. A planned, building-by-building programme often works better than reacting to each complaint and we quote and schedule each building in turn. We work on shopfronts below residential blocks, communal kitchens and washrooms and window and door perimeters on blocks, and what we’re called in for most is brittle perimeter mastic across a building and worn sealant at communal door frames. A single leaking joint is often how a building in Clouston first comes to us: we look at the rest while we are there and tell you what we find.
For buildings around Clouston, we group the work to keep travel and visits down. A list of addresses and photographs lets us quote for them together.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What the job involves on each surface
Tenement and older buildings
Older mastic can contain asbestos and the register is checked before anything is disturbed. If it’s suspected, work stops until it’s tested.
External movement joints
External movement joints take up expansion and contraction. Failed sealant in a movement joint lets water in.
On site: what to expect
On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, with the work itself typically taking a day or two for a single block, longer for an estate programme. Jobs near Clouston are often grouped with others in the same area, to make the most of each trip. Tell us how flexible your dates are.
- We inspect each building and record the joints that have failed.
- You get a fixed quote, per block or for the whole programme.
- Dates and areas are agreed so occupiers can be told.

What happens if it’s left?
Open external joints let water into walls and around frames. That can lead to damp, staining and damage to finishes, which is harder to deal with than resealing. In Scotland, wind-driven rain finds a failed joint quickly, and for a smaller place like Clouston, a repair visit takes planning, so it’s better to act early.
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

Signs you need mastic sealing in Clouston
Sunlight and weather break mastic down over time. The surface chalks, the body stiffens and cracks appear most of all on the sunniest and most exposed elevations.
If one of these sounds familiar, it’s time for a closer look:
- A mix of products and colours from past repairs
- Damaged joints in communal entrances and corridors
- Mastic failing across several blocks on an estate
- Movement joints with sealant missing
Trustees of buildings like Stenness Church can bring frame and external mastic into a planned maintenance list.
What to look for in a quote
- Their plan for phasing and protecting the area
- Proof of insurance
- Is the sealant right for the movement and the substrate?
- What the guarantee covers, and for how long
Looking after the joints
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Encourage occupiers to report problems at frames
- Share your contractor requirements early
- Look at the sunniest and most exposed elevations first
- Share the asbestos register when you send details
Ask residents or tenants to report draughts or leaks round windows early. Early reports catch failures before damage spreads.
One failed perimeter typically means others on the same building are close so a single failure is a sign to check the rest. Doing them together saves going back again and again.
Blocks and managed buildings in Clouston
Clouston sits close to the coast, within about 1 mile. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints, so it’s worth inspecting those sides more often. Clouston is on Scotland’s drier eastern side. External mastic still needs a dry joint and the right temperature, and winter mornings can be frosty. We plan block programmes with some give for it

FAQs: Clouston
Can being near the sea in Clouston affect the sealant we need?
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 one quote cover a number of our buildings near Clouston?
Yes. Portfolio-wide programmes are a regular request. We can phase the programme to suit your budgets and notice periods.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
What if the old mastic contains asbestos?
We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.
Do you work in Clouston?
Yes. We cover Clouston, and the simplest way to start is to phone 01277 525 020 or email drawings and photos.
Which sealant will you use?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
How many days will you need on site?
We plan the time on site around your programme and access. You’ll have an expected duration with the quote.
