Construction mastic for Roberton sites
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
On site: what to expect
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes a day or two on a small fit-out and several weeks on a large multi-storey package, and our waste is bagged and taken away as we go. Travel to smaller Scottish places like Roberton is planned so the job is finished in one visit where possible, so photos, sizes and a full list matter. Outside work also needs a suitable weather window.
- First we take quantities off the drawings and read through the specification.
- A fixed quote sets out the scope, the products and the sequence.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- Areas are sealed plot by plot or floor by floor as the trades hand them over.
- Joints are cleaned, primed where the maker requires it, backed and sealed to the specification.
- We close out snagging and hand over with a 12-month guarantee.
Preparing the site
- Tell us what induction or permit system the site runs
- Share the asbestos register for older buildings
- Let building users know which areas are affected

About our construction mastic in Roberton
Getting a subcontractor through site induction should be simple. We are a Constructionline member and CHAS accredited, and every applicator holds a CSCS card, and we are fully insured. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We work on brick and block movement joints, window and door perimeters and internal decorators’ caulk, and the failures we’re asked to look at most are cracks opening in caulked internal joints and failed sealant in an existing building being refurbished. Most enquiries from Roberton start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
External sealing around Roberton depends on dry faces and the right temperature. We build some give into the plan and agree it with the site manager.
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.

Roberton: questions and answers
Will you fit the mastic around our build programme in Roberton?
Yes, we work to the programme and the sequence the site sets. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Is Roberton too small for you to travel to?
No. Small places get the same service as large ones. Every Scottish council area is within our area. Good photos up front let us bring everything on the first visit.
Can the sealant be colour-matched?
It depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
Can staff carry on working while you are here?
Usually, yes. Phased work can be planned so areas stay in use.
Can you come in just for snagging?
Yes. We clear snags by redoing joints rather than patching them to suit the programme.
Will you just go over the old sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Do you install fire-rated sealant as part of a package?
We install fire-rated sealant where it is the specified product. If the detail calls for collars, wraps or batts instead, we’ll tell you.
What else we do in Roberton
What we can’t put right
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Damage to finishes by other trades after we’ve sealed
- Faulty frames rather than failed sealant
- Specifying the product where the designer hasn’t
Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we will tell you honestly before you book.
What we seal
- Cladding and panel joints
- Internal decorators’ caulk
- Sanitary and kitchen joints
- Brick and block movement joints
- Floor and skirting junctions
- Window and door perimeters
What we are called out for in Roberton
Most mastic snags on new buildings come from sequencing rather than product. If sealant goes in before the last trades are through, it gets knocked, painted over or contaminated, so they end up back on the snag list.
Look out for the following:
- Frame perimeters left unsealed or poorly sealed
- External joints sealed in damp or cold conditions that are now failing
- Oversized or tapered gaps around new frames
- Snag items on joints that need redoing before handover
On any site in or around Roberton, the mastic follows the specification and the programme.
What to look for in a quote
- Who will actually carry out the work
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- How the joint faces will be prepared and primed
- Their plan for phasing and protecting the area
How the quote is worked out
Quotes vary with the job. Expect it to depend on:
- The product specified
- The total length or number of joints
- How much existing material needs removing
- Location, for remote and island sites
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Before you send an enquiry
The more we know, the firmer the quote. When you get in touch, include:
- What the building is and how it’s used
- The product your specification calls for
- How the joints are reached, and at what height
- When you need the work done
A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or call the office on 01277 525 020 or send photos by email if you’d rather talk the job through.
How the job changes by surface
Internal decorators’ caulk
Where the specification calls for it, acrylic decorators’ caulk goes on non-moving internal gaps before painting. It’s paintable and suits gaps that don’t move, and we use a flexible sealant where there’s movement.
External facade and movement joints
Movement joints in the facade are sealed with a product suited to the expected movement. We set the depth with backing rod to avoid three-sided adhesion.
Work for main contractors and building owners
We work for building owners and managing agents on everything from one building to a spread of sites. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Roberton can form part of a wider programme.
