Construction mastic in Castletown, done properly
Refurbishment work needs a slightly different approach from new build. Old beads come out completely, as fresh silicone can’t grip old. New and existing joints then get the same preparation. The enquiries we see most involve external joints sealed in damp or cold conditions that are now failing and oversized or tapered gaps around new frames, on sanitary and kitchen joints, cladding and panel joints and floor and skirting junctions. Searching for sealant specialists in Castletown? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Construction around smaller Scottish places like Castletown 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.
A 12-month guarantee applies to all our work. Should something we installed fail, give us a call on 01277 525 020 or email the details over and we will come back to it.

What sets the cost
The price varies from site to site. It mainly depends on:
- Any access equipment needed
- Specialist products, such as fire-rated or hygienic sealants
- Joint width, depth and condition
- Travel to remote or island sites
What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.
Before you send an enquiry
We can often quote from photographs and a few details. It helps to include:
- Photos of the joints, close up and from further back
- Your programme or deadline
- Whether an asbestos survey exists
- Specification clauses that apply
Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. If you have questions first, call 01277 525 020 or send details through our quote form.
Building owners, agents and FMs in Castletown
CHAS accredited and a Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.
Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so the building keeps working while we do.
Leave it or put it right?
Getting the mastic contractor involved early pays off. We can check joint widths, flag frames with gaps that won’t seal and confirm products against the specification. Leave it late and they turn up on the snag list. Exposed buildings in Scotland take a lot of weather, so it’s worth renewing joints around Castletown before they leak.
There’s no price list, since every building and every scope is different. Call for a quote and we will price your job on its own details.
Why appoint us
- One contact handling all your sites
- Coloured sealants to suit the setting, where available
- Constructionline member for supplier checks
- Products installed to the manufacturer’s instructions

Construction mastic around Castletown: how the place shapes the job
Castletown 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. Building work in Castletown comes under the Building (Scotland) Regulations 2004 and their technical handbooks, with warrants from the local authority verifier. We seal to the specification that sits behind the warrant.
For a contractor working at a hospital such as Dunbar Hospital, 5.5 miles west of Castletown, perimeter and facade sealing is planned around patients and deliveries. For a contractor at a hotel such as Castletown Hotel, less than half a mile west of Castletown, the mastic often has to be finished before a reopening date.
Castletown is about 5 miles east of Thurso, in Highland. We send applicators to Castletown for mastic packages, handled exactly as we handle every other area. Across Highland, 256 places are covered, Castletown among them.
If you need construction mastic in KW14, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. We cover commercial and managed buildings on Calder Square, Main Street and Traill Street and the roads nearby. Just outside Castletown, we also work in Murkle (2 miles west), Dunnet (3 miles north-east), Brough (4 miles north), Bower (4 miles south-east) and Thurso (5 miles west). Where a site is remote or on an island, travel and materials need planning ahead.

Castletown: questions and answers
Can you take on a job at a hospital such as Dunbar Hospital?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Is Castletown off your patch?
No. Small places get the same service as large ones. Every Scottish council area is within our area. Good photographs up front let us bring everything on the first visit.
What’s the quickest route to a quote?
There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
What if there’s asbestos in the old mastic?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
Can you quote from photographs?
That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs typically get a visit.
Can one quote cover more than one building?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
Should maintenance staff do it?
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
