Construction mastic near Grantshouse
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Cost factors for mastic packages
The price varies from site to site. It mainly depends on:
- The product specified
- The site’s rules and procedures
- Phasing around occupants
- Removal of failed or old sealant
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
What to include in your enquiry
Whether it’s one area or a whole building, these details speed things up:
- How the joints are reached, and at what height
- Whether the building will be occupied during the work
- A wide shot and a close-up of the area
- Specification clauses that apply

About our construction mastic in Grantshouse
A typical mastic package covers more than window perimeters: frame perimeters inside and out, caulking to trims and boards where the specification calls for it, sanitary silicone, kitchens, and the final snag list. Splitting those between trades often leaves gaps in responsibility. We work on internal decorators’ caulk, brick and block movement joints and sanitary and kitchen joints, and the usual reasons a site gets in touch are oversized or tapered gaps around new frames and snag items on joints that need redoing before handover. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Grantshouse is the same: the right product in a properly prepared joint.
External sealing around Grantshouse depends on dry faces and the right temperature. We build some give into the plan and agree it with the site manager.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Signs you need construction mastic in Grantshouse
On a live site, contamination is the biggest threat to a new joint. Dust, film adhesive, damp and grease on the joint faces prevent a proper bond.
What tends to prompt an enquiry:
- New external sealant already peeling away
- Failed sealant in an existing building being refurbished
- Internal caulk splitting as the building dries out
- Frame gaps too wide for sealant alone
Window perimeters and facade joints around Grantshouse need correct width, depth and backing rod as much as a neat finish.
What to look for in a quote
- Are they CHAS accredited or on Constructionline?
- How long is the guarantee, and what does it include?
- Will RAMS and insurance details be available?
- Can the work be phased to keep areas open?
Questions about Grantshouse
Is Grantshouse too far out for you?
Not at all: smaller places are covered as well as towns. We work across every Scottish council area. Good photos up front let us bring everything on the first visit.
Can you keep pace with our programme in Grantshouse?
Yes. The mastic is planned around your key stages. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
What joints do you seal on a new build?
External and internal frame perimeters, caulking where it’s specified, sanitary silicone, kitchen joints and snagging before handover. The scope follows your specification.
Which sealant will you use?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Can you quote from photos?
That depends on the size and complexity of the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.
Can staff carry on working while you are here?
In most cases, yes. We phase the work so most of the building stays in use.

Scotland has its own building regulations, and in Grantshouse warrants come from the local authority verifier. The mastic follows the specification that goes with the warrant.

After the work
Once the work is signed off, these steps help:
- Flag uneven or tapered frame gaps early
- Protect sealed areas from following trades
- Share drawings and the specification as soon as possible
- Allow flexibility for external sealing in damp or cold weather
Record which products went where in the handover file. That helps the building owner maintain the joints later and avoids guesswork when joints are renewed. We can confirm the handover information you need when we quote.
One unsealed frame can let water into finished internal areas. On a new building that means remedial work after decorating and possibly a delayed handover. Checking perimeters before internal finishes go on avoids it.
How the job changes by surface
Bathrooms, en suites and washrooms
Across a block of flats or a hotel, sanitary sealing is repeated in every room. One applicator team gives the same finish everywhere.
Internal decorators’ caulk
Acrylic caulk fills internal gaps around trims, boards and frames ahead of decorating. It’s for gaps that stay still and get painted while moving joints need a flexible sealant.
Site staff or a sealant specialist?
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
