What sealant work can’t fix
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. It won’t fix:
- Glazing units that are cracked or misted
- Frame gaps too wide for sealant, which the installer needs to correct
- Designing joint widths or choosing the specification (that sits with the designer)
If in doubt, call the office on 01277 525 020 or email a schedule or drawings and we will say what we think.
Surfaces we seal
- Window and door perimeters
- Brick and block movement joints
- Sanitary and kitchen joints
- Floor and skirting junctions
- Cladding and panel joints
- Internal decorators’ caulk
How we handle construction mastic in Charlestown
Since 2005 we’ve worked alongside main contractors, developers and fit-out firms. Quantities come off the drawings, the sequence is agreed with the site manager and the work follows the trades. For construction mastic on a scheme in Charlestown, send drawings through our quote form, or phone or email us to talk it through. If you have perimeter gaps outside the sealant’s range and mastic snags holding up handover, we can help, on floor and skirting junctions, sanitary and kitchen joints and brick and block movement joints alike. Most enquiries from Charlestown start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
For a site around Charlestown, we plan the mastic in as few trips as the programme allows. Clear drawings, a programme and photos let us bring the right sealants, primers and backing rod first time.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Advice
What the job involves on each surface
Snagging before handover
Snagging is often the final mastic stage. We can work through the snag list area by area, cutting out damaged joints and resealing them properly.
Window and door perimeters
A frame gap that’s too wide can’t just be filled with sealant. Gaps outside the product’s range are raised with the site team.
How the quote is worked out
Quotes vary with the job. It mainly depends on:
- Induction, permit and paperwork requirements
- Distance, for remote addresses
- Access and working height
- The total length or number of joints
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
What we need to price the job
For an accurate fixed quote, we need to understand the site. Useful things to include:
- The postcode of the building
- Any specification or named product
- Asbestos survey details if the building is older
- How the joints are reached, and at what height
Let us know the site, the scope and your timescale, and we will put a fixed quote together. The easiest way is to ring 01277 525 020 or email us.
Questions about Charlestown
Does the sea air around Charlestown change the choice of sealant?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Is Carse Industrial Estate, near Charlestown, within your area?
Yes. Estates, retail parks and business parks around Charlestown, Carse Industrial Estate among them, are all within reach. To start, just phone 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.
Is colour matching possible?
That depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
Does weather affect external mastic work?
Weather matters for external sealing: the joint needs to be dry and within the product’s temperature range. We plan external elevations with that in mind.
Does weather matter for sealant work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Can you come in just for snagging?
Yes. Damaged, missed or untidy joints are stripped and done again properly.
How much does the work cost?
There isn’t a price list, as every site differs. With photos or drawings, we can give you a fixed quote.
When to call us in Charlestown
Dust is the enemy of adhesion on a construction site. Plaster dust, release agents, protective film residue and damp all stop sealant bonding.
It’s worth sending us details if you spot any of the following:
- Window and door perimeters that won’t pass inspection
- Inconsistent sealant finishes from plot to plot
- New external sealant already peeling away
- Sealant knocked or painted over by other trades
Building work at universities like University of the Highlands and Islands, 2.4 miles south-east of Charlestown, is often timed for the summer, mastic included.

Contractors’ notes for Charlestown
Charlestown lies within about 1 mile 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. In Charlestown, as across Scotland, building warrants are issued by the local authority verifier under the Scottish regulations. The mastic package follows the approved specification.
For a contractor working at a hospital such as New Craigs Hospital, 2.3 miles south of Charlestown, perimeter and facade sealing is planned around patients and deliveries. Hotels like North Kessock Hotel (to the east of Charlestown) rarely close for long, so refurbishment mastic is phased floor by floor.
