About our construction mastic in Wasbister
The specification and the programme set the job. If a product is named, that’s what goes in; any alternative we suggest is put to you before anything changes. Joint widths, backing, primers and tooling follow the manufacturer’s guidance, so the joints perform as the designer intended. We work on sanitary and kitchen joints, floor and skirting junctions and window and door perimeters, and what we’re called in for most is existing joints on a refurb that need cutting out and resealing and bath and shower joints scraped during the final clean. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Wasbister it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Construction around smaller Scottish places like Wasbister is often one-off schemes: a school, a health centre, a hotel extension or a few houses. Exposed elevations in Scotland put facade and perimeter joints to work from day one, so the sealant choice matters.
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 are clear about what is covered before work starts.

Should maintenance staff do it?
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

What we’re called out for in Wasbister
Shrinkage and settlement in the first months put new joints under strain. Plaster, screeds, timber and blockwork all shrink as they lose moisture and internal caulk in a moving joint is usually the first to crack. Choosing the right product for each joint reduces that.
Things that typically lead to an enquiry:
- Old sealant on a refurbishment that needs stripping before new work
- Sealant knocked or painted over by other trades
- Cracks opening in caulked internal joints
- Perimeter gaps outside the sealant’s range
Older buildings in the area around Wasbister, such as Skaill House, which lies north-west of Wasbister, need care when sealed: the product has to suit soft or historic materials.

Common questions from Wasbister clients
Can you work around term dates at a campus such as Heriot-Watt University - Orkney Campus?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Will you travel to Wasbister on the island?
Yes, Wasbister is within the area we cover. We cover the whole of Scotland. We group island work where we can and plan around the crossings.
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 on a small fit-out and several weeks on a large multi-storey package. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
Do you install fire-rated sealant as part of a package?
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested details. Fire-stopping design and sign-off sit with the designer and building control.
Can you clear a mastic snag list before handover?
Yes. Damaged, missed or untidy joints are stripped and done again properly, working to your handover date.
Will you stick to the specified products?
The specification decides the product. Product standards such as BS EN 15651 are often named in specifications.
On site: what to expect
Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. For work around Wasbister, we aim for one trip, which is why we ask for photographs and a full list first. Outside work also needs a suitable weather window.

- We agree with the site team which areas come first.
- Each area is sealed when it’s released.

Advice
Looking after the joints
For the best life from the joints:
- Ask cleaners to use soft cloths around fresh sealant
- Get the mastic subcontractor involved early in the programme
- Record the products used in the O&M file
- Stick to the specified sealant rather than a generic substitute
A new structure shifts as it loses construction moisture. Flexible sealants in the right joints handle normal movement while rigid fillers and caulk can crack where movement is larger. If that happens, let us know.
In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Leaks behind showers and basins damage finishes and floors, and the repair falls into the defects period. Getting the product and preparation right first time avoids that.
How the job changes by surface
Bathrooms, en suites and washrooms
In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Each joint is prepared, sealed and finished with a neat tooled line.
External facade and movement joints
Many facade substrates need a primer before sealing. We prime where the manufacturer specifies and work only when conditions suit.
Building and refurbishing in Wasbister
Wasbister lies within about 1 mile of the sea. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, so we check the specified product suits the exposure before the first bead. Projects in Wasbister follow Scotland’s building regulations, with the local authority acting as verifier. We seal to the specification that sits behind the warrant.
Building work at universities like Heriot-Watt University - Orkney Campus (to the south-west of Wasbister) is often timed for the summer, mastic included.

When it isn’t the sealant
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Designing joint widths or choosing the specification (that sits with the designer)
- Frame gaps too wide for sealant, which the installer needs to correct
- Deciding which fire-stopping product a penetration needs
If in doubt, ring 01277 525 020 or email the details over and we will say what we think before you book.
