About our mastic sealing in Port Mholair
In buildings from before 2000, some old mastics contain asbestos. Before we disturb it, we ask to see the asbestos register or survey and if it’s suspected, work stops until it’s tested. We don’t remove asbestos-containing materials. We work on communal kitchens and washrooms, communal entrances and stairwells and shopfronts below residential blocks, and the usual reasons a site gets in touch are window mastic that has split and shrunk and the same joint failures repeated across a portfolio. For commercial sealant work in Port Mholair, you deal with one contact from quote to sign-off, whether it’s one building or several.
Around Port Mholair, outside mastic waits for dry weather and the right temperature. We agree a window with some flexibility.
A 12-month guarantee applies to all our work in Na h-Eileanan Siar. If an installation problem shows up, speak to us on 01277 525 020 or send details through our quote form and we will arrange a return visit.

Owners, agents and contractors
Building owners and managing agents use us on sealant work across single buildings or whole portfolios. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Port Mholair can sit alongside others in a wider programme across Na h-Eileanan Siar.
Leave it or put it right?
Replacing mastic before water gets in is a planned job. After water has got in, there may be damp, damaged plaster or decoration to put right too and occupiers notice. Exposed buildings in Scotland take a lot of weather, and for a smaller place like Port Mholair, a repair visit takes planning, so it’s better to act early.
What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote when you are ready.

- The product specified
- Travel to remote or island sites
- Site requirements such as inductions and permits
- Any access equipment needed
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.

Mastic sealing around Port Mholair: what changes locally
Port Mholair is within about 1 mile of the coast. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do, and they deserve more regular inspection. Port Mholair is in the west of Scotland, the wetter side of the country. Exposed elevations on blocks take a soaking and their mastic shows it. Outside mastic goes on in dry spells, with some flexibility in the programme.
Around Port Mholair, a planned programme renews failed mastic across a building or estate in one go. Site managers at schools like Aird Primary School can fit frame mastic into the summer works.

Your questions answered
Can you quote for mastic across several buildings in and around Port Mholair?
Yes. Planned programmes across a building, block or estate are a core part of this service. We can phase the programme to suit your budgets and notice periods.
Can you take on a job in Port Mholair, on the island?
Yes. Our area covers all of Scotland, cities, towns and islands alike, and that includes island locations such as Port Mholair. Ferry times and the weather set the plan, so we ask for photographs and a full list first.
How long does a typical visit take?
That varies with the scale of the job, though a typical visit usually takes a day or two for a single block, longer for an estate programme. For bigger or phased jobs, we will set out a timescale with the quote.
Can you seal joints high up on a block?
It depends on the building. How upper joints are reached is agreed before work is booked so there are no surprises.
How do you handle work on occupied blocks?
The work is planned around occupiers. We agree the programme so you can notify occupiers, and entrances stay in use.
Do you guarantee the mastic work?
There is a 12-month guarantee on our workmanship and we hold public liability insurance.
Which sealant will you use?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Advice
Keeping the joints sound
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Check sealant joints during planned building inspections
- Avoid piecemeal callouts where you can
- Make it easy for occupiers to report draughts
- Share your contractor requirements early
Ask residents or tenants to report draughts or leaks round windows early. A quick report keeps a small repair small.
Left open, joint edges in render, brick or frames can deteriorate. Once that happens, repairs come before resealing and the job grows.
When to bring in a specialist
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
