Construction mastic in Portskerra, done properly
On a new build, the mastic package is one of the last trades through each area. We work as a mastic subcontractor to main contractors and developers on schemes in Portskerra, following the trades through the building as rooms and elevations become ready. If you have existing joints on a refurb that need cutting out and resealing and caulk cracking where joints are moving more than expected, we can put it right, whatever the surface. One point of contact handles commercial sealant work in Portskerra from the first photographs to the final walk-round, for single jobs and planned programmes alike.
Outside mastic in Scotland needs a dry, frost-clear joint, and in a place like Portskerra that means watching the forecast. A little flexibility in the programme lets external joints go in on suitable days.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Leave it or put it right?
A quick bead over a damaged joint can get an area past inspection, but it won’t last. Sealant can’t grip a contaminated or existing bead. Damaged joints are removed and resealed from clean faces. For buildings near Portskerra, dealing with all the failing joints at once saves return trips. Send photos and we will quote for everything together.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.

Aftercare for building managers
For the best life from the joints:
- Share drawings and the specification as soon as possible
- Keep scrapers and abrasive pads off new beads
- Use the product the specification names
- Protect sealed areas from following trades
Tell the builders’ clean team which areas have new sealant. Blades and abrasive pads are the commonest cause of damage at the final clean so keep them off the joints.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Sealant stretched over an oversized gap won’t last. We flag them as soon as we see them.
Our process
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes a few days on a modest refurbishment and longer on multi-plot or multi-storey schemes, and our waste is bagged and taken away as we go. For work around Portskerra, we aim for one trip, so photographs, sizes and a full list matter. Outside work also needs a suitable weather window.
- Drawings, the sealant specification and your programme come to us for pricing.
- We return a fixed quote that ties the mastic package to your programme.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- We seal each plot or floor as it’s released to us.
- Each joint is prepared, backed to depth and sealed in the product the specification names.
- We close out snagging and hand over with a 12-month guarantee.
Before we start on site
- Send any specification or drawings in advance
- Point out parking and an unloading spot
- For older buildings, check the asbestos register before work

Advice
Questions about Portskerra
Can you keep pace with our programme in Portskerra?
Yes. The mastic is planned around your key stages. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Our building in Portskerra is near the coast: does that change the sealant?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also give us a call on 01277 525 020 or use the quote form. Include photos or drawings if you have them.
Is colour matching possible?
That depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Do you need to see the site first?
It depends on the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.
When can you be on site?
Give us your site hours and any access windows in your enquiry, and we’ll plan around them. You can reach the office between 8am and 5pm, Monday to Friday.
What sealant work can’t fix
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Rework caused by others damaging completed areas
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Defective windows, doors or glazing units (the supplier or installer’s job)
If in doubt, speak to us on 01277 525 020 or email a schedule or drawings and we will say what we think before you book.
Surfaces we seal
- Sanitary and kitchen joints
- Brick and block movement joints
- Window and door perimeters
- Cladding and panel joints
- Floor and skirting junctions
- Internal decorators’ caulk
How the job changes by surface
Snagging before handover
Snags normally come from damage by following trades, missed joints or poor earlier work. Snagging can be included or priced separately.
Fire-rated sealant where specified
Not every penetration suits a sealant. Other products are used for some services and gaps so we will flag where the detail needs something different. Record requirements are agreed with the quote.
Mastic packages on Portskerra sites
Portskerra is within about 1 mile of the coast. 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. Projects in Portskerra follow Scotland’s building regulations, with the local authority acting as verifier. The mastic package follows the approved specification.
On any site in or around Portskerra, the mastic follows the specification and the programme. For a contractor at a hotel such as Melvich Hotel, which lies south of Portskerra, the mastic often has to be finished before a reopening date.

How the quote is worked out
We price every job individually. The main factors are:
- Location, for remote and island sites
- Quantities, in metres or numbers
- Working within restricted access windows
- Removal of failed or old sealant
The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
Before you send an enquiry
Good information means a firmer quote. Helpful details to send:
- The type of building and who uses it
- When you need the work done
- How the joints are reached, and at what height
- Where the site is, with the postcode
Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.
