Your questions answered
Can work at a site such as Dumfries & Galloway College - Stranraer Campus fit around teaching?
Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Our building in Stranraer is near the coast: does that change the sealant?
It can. Coastal exposure works external joints harder than inland weather. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Is it okay to overlay old mastic?
No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the faces are cleaned before resealing. Nothing else gives a bond that lasts.
Do you take on multi-site work?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
Will your applicators have CSCS cards?
Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Facade sealing in Stranraer, done properly
Some clients need every window on a block resealed; others need a few leaking frames sorted. The approach doesn’t change with the size: old sealant out, faces cleaned, depth set and a new bead tooled in. Each job carries our 12-month guarantee. Site teams most often ask us about hard, chalky sealant that no longer flexes and perimeter sealant that has split or peeled away, on cladding panel joints, coping and flashing joints and shopfront frames. A single leaking joint is often how a building in Stranraer first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Scottish towns such as Stranraer see new housing, schools and health centres alongside work on older stone and harled buildings. Harled, rendered, brick and clad elevations each need a different approach to the perimeter and facade joints.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

On site: what to expect
Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before the next one starts. For a unit on an estate in Stranraer, tell us about yard access and site rules. Central premises can need a little more planning for parking.
- We plan access and the order of elevations with the client.
- We only seal when joints are dry and within the product’s temperature range.
- We remove the old bead and check the edges are sound.
- Joints are cleaned, primed if required and fitted with backing rod.
- Facade-grade sealant goes in and is tooled to a tidy concave profile.
- Once signed off, the work carries our 12-month guarantee.
Getting the site ready
- Share the asbestos register for older buildings
- Tell us which areas need to stay in use
- Explain the parking and delivery arrangements

Related advice
Should maintenance staff do it?
Putting right a botched joint often costs more than sealing it well at the start, 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.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Do you need facade sealing in Stranraer?
Sometimes the substrate is the problem: crumbling render, spalling concrete or flaking paint take the sealant with them. When the joint edges need repair first, we say so.
Things that normally lead to an enquiry:
- Facade joints cracked through the middle
- Perimeter joints where frames meet the structure
- Discoloured or dirty facade joints
- Water coming in around window frames
Projects at colleges like Dumfries & Galloway College - Stranraer Campus (to the south-east of Stranraer) tend to run to term dates, so the mastic is planned tightly.
What your quote should include
- Whether old or failed sealant will be cut out, not overlaid
- Which product they’ll use, and why it suits the joint
- Who will actually carry out the work
- What the guarantee covers, and for how long
Facades, frames and programmes in Stranraer
With the shore within about 1 mile, Stranraer counts as a coastal location. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, and the sealant, primer and backing need choosing with that in mind. Stranraer is on Scotland’s wetter western side. We keep internal mastic in hand so wet days aren’t lost.
For contractors refurbishing units at places like Castle Kennedy Industrial Estate, 0.9 miles south-east of Stranraer, the mastic covers cladding panels, roller-door and window perimeters. Work at a hotel such as The George Hotel (to the east of Stranraer) tends to be programmed around bookings, mastic included.

Different surfaces, different methods
Window and door perimeters
Aluminium, PVC-U and timber frames each have their own preparation needs. Primer goes on where the manufacturer specifies it for that substrate.
Precast concrete panels
Joints between precast panels carry real movement. A sealant of the right movement class goes in over backing rod with primer where the product requires it.
