About our mastic sealing in Clachan Seil
Managing agents and housing associations normally need paperwork before anyone starts. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member, with public liability insurance. We work on balcony and threshold joints, communal kitchens and washrooms and external wall and movement joints, and the usual reasons a site gets in touch are movement joints with sealant missing and worn sealant at communal door frames. Whoever orders the work in Clachan Seil, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.
Travel to smaller places like Clachan Seil is planned so several buildings can be done on one trip. Send addresses and photos for a quote covering the batch.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

How a job runs

For work around Clachan Seil, we aim for one trip, which is why we ask for photos and a full list first. External joints need a dry spell as well.

Doing it in-house
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Some joints are best left to specialists: 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.
Common questions from Clachan Seil clients
Does a coastal location like Clachan Seil affect which sealant is used?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We check the specified product suits the exposure and pay close attention to preparation.
Will you price a mastic programme across our Clachan Seil portfolio?
Yes, we quote for single buildings and for programmes across several blocks. We can phase the programme to suit your budgets and notice periods.
Is Clachan Seil in your area?
Yes. We cover Clachan Seil, and the simplest way to start is to ring 01277 525 020 or use the quote form.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
Is asbestos a concern with old mastic?
We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.
Can people stay in the building while you reseal?
Occupiers stay in the building throughout. If any flats or units need access, we will tell you in advance so it can be arranged.
Do you guarantee the mastic work?
Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.
After the work
Regular inspection catches problems early. In particular:
- List the paperwork your organisation requires when you send details
- Include mastic in your cyclical inspections
- Plan resealing building by building rather than complaint by complaint
- Prioritise elevations facing the weather
If a joint we sealed fails within 12 months, tell us and we will look at it. Beyond that, routine checks spot the next round of repairs.
Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.
What sealant work can’t fix
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
- Glazing that needs replacing
- Failed window or door frames, which need a window contractor
If in doubt, speak to us on 01277 525 020 or email a schedule or drawings and we will say what we think.
What we seal
- Balcony and threshold joints
- Communal kitchens and washrooms
- External wall and movement joints
- Shopfronts below residential blocks
- Communal entrances and stairwells
- Window and door perimeters on blocks
Mastic sealing around Clachan Seil: points for this area
Clachan Seil sits close to the coast, within about 1 mile. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first, so it’s worth inspecting those sides more often. Being in the west of Scotland, Clachan Seil gets more rain than eastern areas. The most exposed elevations need checking most often. Programmes allow for wet days.
Around Clachan Seil, a planned programme renews failed mastic across a building or estate in one go. Near Clachan Seil, we review each elevation first so the quote covers what actually needs doing.

Leave it or put it right?

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
