Advice
Facade sealing in Castletown
Installing framed glazing systems isn’t part of our work. We handle the sealant joints that surround those elements: perimeter joints where frames meet the structure, panel joints and window perimeters with products suited to facade or glazing perimeter joints. If you’re dealing with cold air coming in at window perimeters and discoloured or dirty facade joints, we can put it right, on shopfront frames, coping and flashing joints and perimeter joints where frames meet the structure alike. Whoever orders the work in Castletown, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Outside mastic in Scotland needs a dry, frost-clear joint, and in a place like Castletown that means watching the forecast. We build some give into the plan and agree it with the site manager.
A 12-month guarantee applies to all our work. Should something we installed fail, call the office on 01277 525 020 or email a schedule or drawings and we’ll come back to it.

Sites and facades in and around Castletown
Castletown sits close to the coast, within about 1 mile. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, and the sealant, primer and backing need choosing with that in mind. 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 to the west of Castletown, perimeter and facade sealing is planned around patients and deliveries.
Castletown is about 5 miles east of Thurso, in Highland. We cover Castletown and the rest of Highland, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Across Highland, 256 places are covered, including Castletown.
Commercial sites across KW14 are covered. We cover commercial and managed buildings on Calder Square, Main Street and Traill Street and the roads nearby. We also cover 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, so the full address helps from the start.
Near you in Castletown
Nearby you will also find Thurso Castle (4.4 miles west) and Dunbar Hospital (5.5 miles west). For a walk, there’s St John's Loch.
Quoting for work in Castletown
What shapes the price:
- Induction, permit and paperwork requirements
- Any access equipment needed
- Removal of failed or old sealant
- Quantities, in metres or numbers
The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.
What to include in your enquiry
A good diagnosis starts with the right details. Let us know:
- Whether the building will be occupied during the work
- A wide shot and a close-up of the area
- Access details, including height
- Asbestos survey details if the building is older
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, speak to us on 01277 525 020 or send photos by email.
Why it’s worth doing now in Castletown
Every shower drives water through a split perimeter bead. Behind the frame, that can mean damp plaster, stained ceilings, corroded fixings and damaged insulation. Resealing early costs far less than repairing what the water reaches. Around smaller places like Castletown, halls, stores and seasonal buildings may not be checked often, giving water time to get in. Early resealing prevents it.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Common questions from Castletown clients
Is Castletown off your patch?
No. Small places get the same service as large ones. We work across every Scottish council area. Good photos up front let us bring everything on the first visit.
Can you work on a hospital site such as Dunbar Hospital?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit before quoting.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
Do we need an asbestos check before resealing?
It’s worth checking in any building from before 2000. The duty to manage asbestos sits with the dutyholder, so ask for it before we start. If asbestos is suspected, work stops until it is tested.
Does the weather affect the work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Common problems we fix in Castletown
Three-sided adhesion is a classic installation fault. With no backing, the sealant is restrained and tears as the joint moves.
These are often picked up first by site or facilities staff:
- Failed seals around shopfront and entrance frames
- Damp patches beside frames after rain
- Sealant pulling away from frames or panels
- Draughts around frames and panels
Work at a hotel such as Castletown Hotel (to the west of Castletown) tends to be programmed around bookings, mastic included.

- Is the sealant right for the movement and the substrate?
- How long is the guarantee, and what does it include?
- Whether old or failed sealant will be cut out, not overlaid
What we can’t put right
We check first that sealant really is the fix. It won’t put right:
- Cracked or spalling substrates that need repair before sealing
- Movement beyond what any sealant can handle
- Replacing glass or failed glazing units
If you’re not sure, just speak to us on 01277 525 020 or email us and we will give you a straight answer before you book.
