Mastic sealing for Scrabster sites
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Maintenance after handover
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Share your contractor requirements early
- Log resealing dates block by block
- Start inspections with the most exposed faces
- Have the asbestos survey to hand for older buildings
Encourage occupiers to report water or draughts at frames. Early reports catch failures before damage spreads.
Mastic fails gradually, then all at once in a wet spell. Resealing when cracking first shows avoids water damage and saves internal repairs.
Mastic sealing for commercial buildings in Scrabster
Managing agents and housing associations usually need paperwork before anyone starts. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We’re a Constructionline member and CHAS accredited, and we carry public liability insurance. If you have mastic failing across several blocks on an estate and failed external movement joints, we can help, on external wall and movement joints, communal kitchens and washrooms and shopfronts below residential blocks alike. Whether you call it commercial sealant work, mastic application or joint sealing, in Scrabster it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In smaller Scottish places like Scrabster, managed property is mostly small blocks, sheltered housing, hotels and community buildings. Exposed walls take Scottish weather hard, and frame mastic shows it first.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Site staff or a sealant specialist?
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Mastic sealing in Scrabster: the local picture
Scrabster 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, and they deserve more regular inspection. Scrabster is on Scotland’s drier eastern side. Cold mornings still limit when outside mastic can go on.
If you look after a block within reach of Thurso station, which lies south-east of Scrabster, frame and balcony mastic can be renewed on one programme. If your remit includes a building such as Thurso High School, frame and door mastic can be programmed for the holidays.
Scrabster is about 2 miles north-west of Thurso, in Highland. We cover commercial sites throughout Scrabster, whether it’s a single job or part of a planned programme. Our Highland coverage takes in 256 places.
Anyone looking for mastic sealing in KW14 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. For a building on Clett Terrace, St Clair Avenue and Holborn Place or nearby, send details and we’ll quote for mastic joints. Close to Scrabster, our area also takes in Thurso (2 miles south-east), Glengolly (3 miles south), Janetstown (3 miles south), Forss (3 miles west) and Murkle (4 miles east). Remote and island addresses take more planning, from travel and ferries to the weather, so give the site location in your enquiry.

Honest limits
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Masonry that has broken away beside the joint
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Broken glass or failed sealed units
If in doubt, call 01277 525 020 or email the details over and we’ll say what we think before you book.

Different surfaces, different methods
Window and door perimeters on blocks
We normally work through a block’s windows in a planned order. Access is agreed with you before the quote is fixed.
Planned maintenance
Planned resealing replaces emergency callouts and keeps budgets predictable.
Our process
Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Where we can, we combine work around Scrabster with other jobs nearby, to make the most of each trip. Let us know if your dates have any give.
- First we look at the mastic on each building and note what needs replacing.
- We send a fixed quote that sets out the joints, the products and the programme.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Old sealant is stripped and each face prepared back to firm material.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Before we start on site
- Have the specification and drawings to hand
- Agree which areas must stay open
- Flag any permit to work we’ll need

Your questions answered
Can being near the sea in Scrabster affect the sealant we need?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Will you take on a block within reach of Thurso station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Photos of each elevation help us quote accurately.
Do you do block-wide mastic programmes?
Yes. We survey and price each building, then work through them in order, and the programme can start with the worst.
Is mastic sealing guaranteed?
A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.
What paperwork can you provide?
Our credentials include CHAS, Constructionline and public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
Do you seal on top of existing sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
