Common questions from Diuranais clients
Will you fit the mastic around our build programme in Diuranais?
Yes. Send the programme and drawings, and we will plan the mastic to suit the stages. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Is Diuranais off your patch?
No. Places such as Diuranais are covered as much as the big towns. We work across every Scottish council area. Good photographs up front let us bring everything on the first visit.
How do you choose the sealant?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Do you take on small jobs?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
Can staff carry on working while you are here?
Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.
How do we ask for a quote?
You can use the quote form on this site; alternatively, ring 01277 525 020 or use the quote form. Photos, drawings or a joint schedule help us quote quickly.
Do you guarantee new-build sealant work?
Each package is signed off with a 12-month workmanship guarantee. Damage by others after we have finished isn’t covered.
Construction mastic for commercial buildings in Diuranais
The programme rarely stands still, so the mastic package has to flex with it. We agree a sequence at the start and adjust it as the site manager releases areas. Sealing too early only means coming back once others have damaged it. If you are dealing with bath and shower joints scraped during the final clean and missed perimeter joints on a new elevation, we can put it right. Searching for sealant specialists in Diuranais? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Construction around smaller Scottish places like Diuranais is often one-off schemes: a school, a health centre, a hotel extension or a few houses. The mastic still needs to suit exposed elevations and Scottish weather.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

Leave it or put it right?
Leaving mastic to whichever trade is fitting the element can look cheaper on paper. The result tends to be uneven finishes and arguments about who should seal what. One mastic subcontractor for the lot keeps it simple and a consistent finish. In Scotland, wind-driven rain finds a failed joint quickly, so it’s worth renewing joints around Diuranais before they leak.
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

When to call us in Diuranais
Most mastic snags on new buildings come from sequencing rather than product. If sealant goes in before the last trades are through, it gets knocked, painted over or contaminated.
Site and facilities staff are often the first to spot these:
- Mastic snags holding up handover
- Frame gaps too wide for sealant alone
- Early adhesion failures on new external joints
- Failed sealant in an existing building being refurbished
For a contractor at a hotel such as Smoo Cave Hotel, 1.2 miles east of Diuranais, the mastic often has to be finished before a reopening date.
Questions to ask before you book
- Health and safety accreditation such as CHAS
- The terms of the workmanship guarantee
- How joint depth will be controlled
- Whether primer will be used where the manufacturer specifies it
What we can’t put right
We check first that sealant really is the fix. It won’t put right:
- Deciding which fire-stopping product a penetration needs
- Rework caused by others damaging completed areas
- Oversized gaps that need packing or adjustment by others
If in doubt, speak to us on 01277 525 020 or send photos by email and we’ll say what we think before you book.
What we seal
- Floor and skirting junctions
- Cladding and panel joints
- Window and door perimeters
- Internal decorators’ caulk
- Sanitary and kitchen joints
- Brick and block movement joints
Looking after the joints
After handover, these steps help:
- Check frame gaps are within the sealant’s range before sealing
- Allow flexibility for external sealing in damp or cold weather
- Don’t schedule sealing before decorators and flooring are done
- Keep product details for future maintenance
Our 12-month guarantee covers the workmanship from sign-off. Damage by others isn’t a workmanship fault.
One unsealed frame can let water into finished internal areas. That typically means redoing finishes in a completed area and possibly a delayed handover. A check of every frame before decorators start is worth the time.
How the job changes by surface
Internal decorators’ caulk
Where the specification calls for it, acrylic decorators’ caulk goes on non-moving internal gaps before painting. It’s paintable and suits gaps that don’t move while moving joints need a flexible sealant.
Snagging before handover
Damaged, missed or untidy joints make up most snag lists. We price snagging as part of the package or as a separate visit, depending on what suits the programme.
Construction mastic around Diuranais: what changes locally
Diuranais lies within about 1 mile of the sea. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Diuranais is on Scotland’s wetter western side. We keep internal mastic in hand so wet days aren’t lost.
Sites around Diuranais get mastic sealed to the drawings and the programme, nothing improvised.
