Surface by surface
Facade and cladding joints
Facade joints move every day as panels warm and cool. They need a sealant with the right movement capability, laid at the right depth. Access, such as scaffold already up, is agreed before the price is fixed.
Fire-rated seals where specified
Fire-rated sealant is only one type of fire-stopping product. Other products, such as collars, wraps and batts, are specified for different services, so we will flag it if the detail needs a different product.
Commercial mastic work in Unthank
Commercial occupiers rarely want a floor out of action for sealant work. Tell us your site hours and access windows and we will plan around them; phased work can also be planned so areas stay in use. That applies whether the building is an office, a shop, a hotel, a college or a care home. We work on window and door perimeters, floor and threshold joints and washrooms and tea points, and what we are called in for most is earlier reseals applied straight onto the failed bead and greasy, split joints in a kitchen or tea point. Most enquiries from Unthank start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Occupied buildings in Unthank need the work phased: we agree the order with you and hand back each area with its cure time.
For a job around Unthank, the Scottish weather is part of the planning: outside joints need dry, frost-clear surfaces, so we agree a window with some give in it. Internal joints can be done whatever the day brings.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Shops, offices and hotels in and around Unthank
The east of Scotland, where Unthank is, gets less rain than the west. Winter frost and damp frames still stop outside sealing on some days. Outside work is booked with that in mind
A hotel such as Northern Hotel (to the south of Unthank) shows how much sealant a hospitality building has on show, from bathroom joints to the bar.

General trades versus a specialist
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Common questions from Unthank clients
Does your area include sites such as Brechin Business Park, near Unthank?
Yes, sites like Brechin Business Park are within our area, along with the rest of Unthank. To start, just call 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Can you supply sealant in our brand colour for a site in Unthank?
Yes, we can normally get close to most finishes from the product’s colour range. Available colours for the product are confirmed with the quote.
How soon can the area be used again?
We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.
How many days will you need on site?
It depends on the scope, though a typical visit normally takes a few hours for one area, or a planned series of visits across a bigger building. Larger or phased jobs take longer, and we will give you a timescale with the quote.
What site paperwork can you provide?
We confirm documents at quote stage: RAMS, an insurance certificate and CSCS details are the usual requests. Every applicator holds a CSCS card.
Is it OK to apply fresh sealant over existing beads?
Every failed bead is cut out completely. Laying new silicone on old gives it nothing to grip.
Which sealant will you use?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Why deal with it now?
On many buildings the mastic was done by whichever trade was on site. Choosing the product, setting the depth and preparing the faces are what a specialist brings. It shows over the following seasons rather than at handover. Exposed buildings in Scotland take a lot of weather, so it’s worth renewing joints around Unthank before they leak.
A quote for sealant joints depends on how many there are, their condition and the access, plus any specification you’re working to. Ask us for a fixed quote.

After the work
Once the work is signed off, these steps help:
- Keep barriers up until the new sealant has cured
- Note dates and locations of sealant work for future planning
- Report cracked or peeling sealant early
- Make sure contractors see the asbestos survey before cutting out old mastic
Let your cleaning contractor know what’s new. Scourers, blades and harsh products shorten a bead’s life.
An open joint in a food area or toilet collects dirt and moisture that cleaning can’t reach. Environmental health officers look at how cleanable surfaces are, so sound, smooth joints matter.
What we’re called out for in Unthank
A split down the middle of the bead tells a different story. That usually means the joint stretched further than the product could cope with because the bead was too thin, the joint over-stretched or the movement class wrong. Replacing it like for like rarely holds.
Look out for the following:
- A top-up bead over failed sealant, now lifting
- Movement joints packed with grit and debris
- Black mould through washroom sealant that won’t clean off
- Greasy, split joints in a kitchen or tea point
For tenants and agents on sites such as Brechin Business Park, 1.2 miles to the south-west of Unthank, office fit-outs, reception joints and window perimeters are the usual sealant work.
