How we handle mastic sealing in Clachan Shannda
We diagnose before we prescribe: what has failed, what caused it and whether new sealant will actually solve it. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in, with backing rod setting the depth where it’s needed. Most enquiries involve failed external movement joints and a mix of products and colours from past repairs, across balcony and threshold joints, communal entrances and stairwells and window and door perimeters on blocks. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Clachan Shannda is the same: the right product in a properly prepared joint.
Around Clachan Shannda, outside mastic waits for dry weather and the right temperature. Programmes allow for the weather.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Keeping the joints sound
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Plan resealing building by building rather than complaint by complaint
- Encourage occupiers to report problems at frames
- Share your contractor requirements early
- Protect low-level joints in entrances
If a joint we sealed fails within 12 months, tell us and we’ll look at it. Beyond that, routine checks spot the next round of repairs.
One failed perimeter usually means others on the same building are close, so it pays to look at the whole elevation. Doing them together saves going back again and again.
Doing it in-house
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
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.
Signs you need mastic sealing in Clachan Shannda
Frames, panels and masonry expand and contract through the year, and the sealant takes up that movement. A joint that was too narrow, too thin or the wrong product can’t cope and fails early.
Common reasons buildings call us in:
- Old repairs sealed over failed mastic
- The same joint failures repeated across a portfolio
- Cracked, hardened mastic round windows on a block
- Open joints in brickwork or panels
Around Clachan Shannda, a planned programme renews failed mastic across a building or estate in one go.
Questions to ask before you book
- Their public liability cover
- What site paperwork they can supply
- What the guarantee covers, and for how long
- Can the work be phased to keep areas open?
Your questions answered
Our building in Clachan Shannda 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. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Can you quote for mastic across several buildings in and around Clachan Shannda?
Yes, we quote for single buildings and for programmes across several blocks. Residents are given notice through you, and the work moves building by building.
Do you supply RAMS and insurance details?
We are CHAS accredited, a Constructionline member and carry public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
What if the old mastic contains asbestos?
Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and the quote will be based on it.
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.
Does weather matter for sealant work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
For managing agents and facilities managers
As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
