Construction mastic in Charleston, done properly
We work to the specification and the programme. Where the specification names a product, we use it. Joint widths, backing, primers and tooling follow the manufacturer’s guidance, so the joints perform as the designer intended. Site teams most often ask us about perimeter gaps outside the sealant’s range and external joints sealed in damp or cold conditions that are now failing, on internal decorators’ caulk, sanitary and kitchen joints and floor and skirting junctions. A specialist sealant contractor works differently from a general builder: in Charleston, that means joint design, primers and backing rod as standard.
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.
Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Why act early in Charleston
Refurbishments sometimes budget for new windows when the frames are sound and only the seal has failed. If the frame is in good order, cutting out and resealing the perimeter can be all it needs and that’s a far smaller job. If the frame is life-expired, we will tell you. In a Scottish city, access often needs scaffold, permits or factor approval, so it makes sense to renew every failing joint while it’s in place.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Honest limits
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be one of these:
- Frame gaps too wide for sealant, which the installer needs to correct
- Damage to finishes by other trades after we’ve sealed
- Faulty frames rather than failed sealant
If in doubt, call the office on 01277 525 020 or email us and we will say what we think before you book.
Surfaces we seal
- Floor and skirting junctions

Keeping the joints sound
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Keep scrapers and abrasive pads off new beads
- Check frame gaps are within the sealant’s range before sealing
- Allow flexibility for external sealing in damp or cold weather
- Put any product change through the designer first
At handover, keep the product details with the O&M information. That helps the building owner maintain the joints later and avoids guesswork when joints are renewed. Tell us what records you need and we’ll confirm with the quote.
External joints sealed in poor weather are a common cause of early failure. Holding off until conditions suit avoids callbacks so external sequencing builds in some flexibility.
Site staff or a sealant 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.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
FAQs: Charleston
How is mastic work on a tenement’s shared parts in Charleston usually organised?
Normally the owners agree it together, and a property factor often handles the arrangements. One quote can cover a close or the whole block.
Could you schedule work at a campus like University of Dundee for the vacation?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we will confirm them alongside the quote.
When can the area be used after sealing?
We will confirm how long the chosen product needs to cure.
Do you guarantee new-build sealant work?
Our workmanship carries a 12-month guarantee from sign-off. The guarantee covers our work, not later damage by other trades.
Do you work in Charleston?
Yes. We cover Charleston, and the simplest way to start is to ring 01277 525 020 or send details through our quote form.
Do you do fire-rated sealing on new builds?
Where it’s specified, yes, working to the specification and the manufacturer’s installation guidance. We will flag if the detail needs a different product.
What joints do you seal on a new build?
The scope comes from the specification and drawings, but frames, sanitary, kitchens, caulk where specified and snagging are typical.
Construction mastic around Charleston: what changes locally
With the shore within about 2 miles, Charleston 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, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. There are several hotels within about 2 miles of Charleston. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
New wings at hospitals like Ninewells Hospital, 0.7 miles south of Charleston, bring long runs of window and panel joints to seal. Projects at colleges like Dundee and Angus College - Kingsway Campus, 2.4 miles east of Charleston, tend to run to term dates, so the mastic is planned tightly. When units on a site such as Wester Gourdie Industrial Estate, less than half a mile west of Charleston, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
