Keeping the joints sound
To get the most from the new sealant:
- Put any product change through the designer first
- Ask installers to correct oversized gaps first
- Ask cleaners to use soft cloths around fresh sealant
- Don’t schedule sealing before decorators and flooring are done
After we’ve sealed an area, it helps to keep other trades from damaging the joints. New beads should be left to cure before cleaning or decorating nearby; we confirm the time for each product.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Sealant stretched over an oversized gap won’t last, so the installer needs to correct it first. We flag them as soon as we see them.
How we handle construction mastic in Unthank
Mastic tends to be one of the final packages before handover. We work as a mastic subcontractor to main contractors and developers on schemes in Unthank. If you’re dealing with early adhesion failures on new external joints and failed sealant in an existing building being refurbished, we can help. A single leaking joint is often how a building in Unthank 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.
Construction around smaller Scottish places like Unthank is often one-off schemes: a school, a health centre, a hotel extension or a few houses. The mastic still needs to suit exposed elevations and Scottish weather.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

What else we do in Unthank
General trades versus a specialist
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
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.
Questions we are asked in Unthank
Do you cover business parks and estates near Unthank, such as Brechin Business Park?
Yes. We cover Unthank and the area around it, including industrial estates, business parks and retail parks such as Brechin Business Park. Photos and a short description are enough for a first look.
Is Unthank too small for you to travel to?
Not at all. Unthank is within our area. We work across every Scottish council area. We plan jobs in smaller places so return trips are kept to a minimum.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
What will the job cost?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.
Can you work while the building is occupied?
Normally, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
Are you CHAS accredited?
We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. Public liability insurance of five million pounds is in place too.
Owners, agents and contractors
Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.
Building owners and managing agents use us on everything from one building to a spread of sites around Unthank. One quote can cover more than one site, so there’s one set of paperwork to deal with.
Different surfaces, different methods
Window and door perimeters
Internal perimeters are usually sealed with a paintable product where decorating follows. The specification decides which with colours matched to the frame where needed.
External facade and movement joints
External movement joints often need primer, depending on the substrate. Primer goes on where the sealant maker calls for it and work only when conditions suit.
Construction mastic in Unthank: the local picture
Unthank is on Scotland’s drier eastern side. Winter mornings can still bring frost and condensation on steel and glass. External dates keep a little give. Projects in Unthank follow Scotland’s building regulations, with the local authority acting as verifier. We seal to the specification that sits behind the warrant.
Hospital estates such as Stracathro Hospital (to the north-east of Unthank) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. For contractors at a school such as Brechin High School, sealing has to be finished before term starts. Hotels like Northern Hotel (0.6 miles south of Unthank) rarely close for long, so refurbishment mastic is phased floor by floor.

What we can’t put right
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:
- Damage to finishes by other trades after we have sealed
- Specifying the product where the designer hasn’t
- Deciding which fire-stopping product a penetration needs
If you are not sure, just call the office on 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.

- Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.
