Photos, a specification or a quick description of the joints is enough to start a fixed quote.
When it isn’t the sealant
Being straight saves everyone time. New sealant won’t cure:
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Joints damaged after sign-off by following trades
- Deciding which fire-stopping product a penetration needs
Not sure which it is? You can speak to us on 01277 525 020 or email us and we will tell you honestly.
What we seal
- Brick and block movement joints
- Sanitary and kitchen joints
- Internal decorators’ caulk

Construction mastic in Scrabster
We work to the specification and the programme rather than whatever product is to hand. 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. We work on cladding and panel joints, internal decorators’ caulk and brick and block movement joints, and the usual reasons a site gets in touch are window and door perimeters that won’t pass inspection and a long mastic snag list close to completion. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Scrabster, that means joint design, primers and backing rod as standard.
Outside mastic in Scotland needs a dry, frost-clear joint, and in a place like Scrabster that means watching the forecast. A little flexibility in the programme lets external joints go in on suitable days.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Keeping the joints sound
To get the most from the new sealant:
- Record the products used in the O&M file
- Release areas for mastic once other trades have finished in them
- Keep scrapers and abrasive pads off new beads
- Brief following trades on areas that have been sealed
Tell the builders’ clean team which areas have new sealant. Blades and abrasive pads are the commonest cause of damage at the final clean, so stick to soft cloths and gentle cleaners near sealant.
Snag items left to the last week put handover at risk. A planned close-out through each area as it completes keeps the list short.
Contractors’ notes for Scrabster
With the shore within about 1 mile, Scrabster counts as a coastal location. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, so we check the specified product suits the exposure before the first bead. In Scrabster, as across Scotland, building warrants are issued by the local authority verifier under the Scottish regulations. Our job is to seal to that specification.
On a healthcare site such as Dunbar Hospital (1.9 miles south of Scrabster), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. School extensions, at buildings such as Thurso High School, normally run to the summer holidays, mastic included.
Scrabster is about 2 miles north-west of Thurso, in Highland. We cover Scrabster and the rest of Highland, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Scrabster is one of 256 places in Highland on our list.
Work on mastic packages is covered throughout KW14, for business premises of every kind. For a building on Clett Terrace, St Clair Avenue and Holborn Place or nearby, send details and we will quote for mastic packages. Close to Scrabster, our area also takes in Thurso (2 miles south-east), Glengolly (3 miles south), Janetstown (3 miles south), Forss (3 miles west) and Murkle (4 miles east). Where a site is remote or on an island, we plan travel and materials carefully, so include the location in your enquiry.

On site: what to expect
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. For a building near Scrabster, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.
- First we look at the scope on site or from drawings.
- A fixed quote sets out scope, products and phasing.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- Sealing follows the programme as areas are released.
- Problems we find, such as oversized gaps, are raised right away.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
Before we start on site
- Send any specification or drawings in advance
- Let building users know which areas are affected
- Arrange parking or a loading space
Getting a fixed quote
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

Different surfaces, different methods
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.
Kitchens and utility areas
On commercial kitchen fit-outs, hygienic sealants are often specified. We follow the specification and seal to a smooth, cleanable finish.

Scrabster: questions and answers
Can you work on a hospital site such as Dunbar Hospital?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is Scrabster too far out for you?
No. Small places get the same service as large ones. We cover the whole of Scotland. Good photos up front let us bring everything on the first visit.
What happens if the weather stops external sealing?
External sealant needs a dry joint and a temperature within the product’s range. Damp, frost or condensation on frames can stop work.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Are you insured?
Yes. We’re fully insured, and the certificate can go with your quote.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Can you send site paperwork?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.
Site staff or a sealant specialist?
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.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
