Construction mastic near Stromness
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Different surfaces, different methods
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.
Fire-rated sealant where specified
Not every penetration suits a sealant. Other products are used for some services and gaps so we will flag where the detail needs something different. Tell us what records you need and we will confirm with the quote.
About our construction mastic in Stromness
Perimeter sealing outside needs a dry joint and the right temperature. Each sealant has a temperature range, and damp, frost or condensation on frames stops work so it helps to sequence elevations with some flexibility. Internal sealing often fills those days. We work on internal decorators’ caulk, floor and skirting junctions and window and door perimeters, and the usual reasons a site gets in touch are perimeter gaps outside the sealant’s range and old sealant on a refurbishment that needs stripping before new work. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Stromness is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Outside mastic in Scotland needs a dry, frost-clear joint, and in a place like Stromness that means watching the forecast. A little flexibility in the programme lets external joints go in on suitable days.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

When to call us in Stromness
Frames installed with uneven gaps make perimeter sealing harder. Every product has limits on how wide a joint it can bridge and gaps beyond it need packing or adjusting by the frame installer. We flag them early rather than filling them with sealant that won’t last.
Typical triggers for a call:
- Frame gaps too wide for sealant alone
- Early adhesion failures on new external joints
- Bath and shower joints scraped during the final clean
- Snag items on joints that need redoing before handover
For contractors on a campus like Heriot-Watt University - Orkney Campus, which lies north of Stromness, facade and perimeter sealing has to fit around students and term dates.
What your quote should include
- Whether old or failed sealant will be cut out, not overlaid
- Can the work be phased to keep areas open?
- Their approach to joint depth and backing
- Their pre-qualification and accreditations
Sites and facades in and around Stromness
Stromness lies within about 1 mile of the sea. Coastal exposure means perimeter and cladding joints work harder than on an inland job, and the sealant, primer and backing need choosing with that in mind. For an island location such as Stromness, work is planned around ferry crossings and the weather. Everything for the package travels with us, so drawings and quantities matter.
Projects at schools like stromness primary school work to term dates, so mastic is programmed tightly. For a contractor at a hotel such as Royal Hotel (under half a mile east of Stromness), the mastic often has to be finished before a reopening date.

How the quote is worked out
These are the things that shape the price:
- Access and working height
- Removal of failed or old sealant
- Phasing around occupants
- Site requirements such as inductions and permits
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
What to include in your enquiry
It doesn’t need to be a full survey. These details are enough to start:
- The postcode of the building
- Any specification or named product
- A wide shot and a close-up of the area
- Your programme or deadline
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

Advice
Your questions answered
Can you take on a job in Stromness, on the island?
Yes. Islands are part of our area, Stromness included. We group island work where we can and plan around the crossings.
Will you plan work around the academic year at somewhere like Heriot-Watt University - Orkney Campus?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
When can you be on site?
Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
Is colour matching possible?
That depends on the product specified. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.
What does a mastic package normally include?
It depends on the specification, but most packages include frame perimeters, sanitary and kitchen joints, caulking where specified and a snagging pass.
Do your applicators hold CSCS cards?
We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. We’re also fully insured, with five million pounds of public liability cover.
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.
After the work
Your facilities or cleaning team can help the joints last. Share these points with them:
- Keep product details for future maintenance
- Don’t schedule sealing before decorators and flooring are done
- Ask for joint and product checks before the package is urgent
- Brief following trades on areas that have been sealed
Expect some settlement in the first months. The right product in each joint copes with that. We can advise if a joint needs a different product.
In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Water gets behind trays, vanity tops and panels. Proper preparation, with the right silicone first time, keeps it off the defects list.
Site staff or a sealant specialist?
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
