How we handle facade sealing in St Marys
Facade sealants sit in the sun, rain and frost every day. Life depends on movement, weathering, product choice and the quality of the original work. When it fails, the whole bead is cut away and the joint rebuilt. If you’re dealing with hard, chalky sealant that no longer flexes and water coming in around window frames, we can put it right, on cladding panel joints, window and door perimeters and perimeter joints where frames meet the structure alike.

City-centre sites in Scotland usually mean booked deliveries, tight storage and shared access. We work to the programme and the site rules, with CSCS-carded applicators.
We stand by our work with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

What sets the cost
The price varies from site to site. It mainly depends on:
- Backing rod, priming and other preparation
- Quantities, in metres or numbers
- Specialist products, such as fire-rated or hygienic sealants
- Location, for remote and island sites
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.
Before you send an enquiry
Whether it’s one area or a whole building, the same details help:
- Any specification or named product
- Whether the building will be occupied during the work
- Whether an asbestos survey exists
- Clear photos of the problem areas
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.
Doing it in-house
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
When to call us in St Marys
A frequent fault is a bead stuck to the joint’s rear face as well as its sides. Without rod or bond-breaker tape, the bead is held back.
Site and facilities staff are often the first to spot these:
- Cold air coming in at window perimeters
- Discoloured or dirty facade joints
- Failed seals around shopfront and entrance frames
- Cladding panel joints that have opened up
For contractors on a campus like University of Abertay Dundee, which lies south-east of St Marys, facade and perimeter sealing has to fit around students and term dates.

Facade sealing in St Marys: the local picture
St Marys lies within about 3 miles of the sea. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, so joint design, primers and product choice deserve extra care. Scotland has its own building regulations, and in St Marys warrants come from the local authority verifier. Our job is to seal to that specification.
School extensions, at buildings such as Lawside Academy, usually run to the summer holidays, mastic included. Recladding or extending a unit at a site like Dryburgh Industrial Estate, 0.6 miles south of St Marys, brings panel joints and frame perimeters into the programme.
St Marys is about 2 miles north-west of Dundee, in Dundee. Businesses, contractors and managing agents in St Marys can call on us for facade joints. 28 places across Dundee fall within our area, St Marys among them.

Your questions answered
Would you work within a site like Kings Cross Hospital?
Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.
Could you schedule work at a campus like University of Abertay Dundee for the vacation?
Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
How do you choose the sealant?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
How is access to upper-level joints handled?
That varies with the building and the access on offer. Share what access exists or is planned when you send details.
Which sealant do you use on facades?
The product follows the joint’s movement, the surfaces and the specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing, and we work to what is specified.
Do we need an asbestos check before resealing?
In older non-domestic buildings, old sealant can contain asbestos. The dutyholder’s asbestos register should be checked first, and if anything is suspected, we stop until it’s tested. Removal of asbestos isn’t something we do.
Are you fully insured?
Yes. We’re fully insured, including public liability cover.

What the job involves on each surface
Perimeter joints at frames and structure
Perimeter joints at frames often show their age first. We cut them out, prepare both faces and reseal to the specification with a product suited to glazing perimeters.
Precast concrete panels
Precast panel joints have to absorb thermal and structural movement. We use a sealant with the right movement capability, set over backing rod.
