About our construction mastic in Tarbert
Mastic follows everyone else, which means it absorbs every delay upstream. The sequence is set with the site team and updated as plots or floors are handed over. That keeps the work right first time and saves rework. The enquiries we see most involve bath and shower joints scraped during the final clean and internal caulk splitting as the building dries out, on floor and skirting junctions, internal decorators’ caulk and sanitary and kitchen joints. Searching for sealant specialists in Tarbert? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
In smaller places such as Tarbert, building work tends to be single schemes rather than big developments. The mastic still needs to suit exposed elevations and Scottish weather.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Cost factors for mastic packages
Your fixed quote is built from the real scope. It takes account of:
- Site requirements such as inductions and permits
- How much there is to seal
- Access and working height
- Specialist products, such as fire-rated or hygienic sealants
What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.
Details that help us quote
A few photographs plus some basic facts will normally do. It helps to include:
- The type of building and who uses it
- Approximate linear metres or a joint schedule
- Where the site is, with the postcode
- How the joints are reached, and at what height
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.
When something else is needed
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Damage to finishes by other trades after we’ve sealed
- Glazing units that are cracked or misted
- Approving fire stopping as compliant
Not sure which it is? You can call 01277 525 020 or use the quote form and we’ll tell you honestly before you book.

Questions we’re asked in Tarbert
Our building in Tarbert is near the coast: does that change the sealant?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Will you fit the mastic around our build programme in Tarbert?
Yes, we work to the programme and the sequence the site sets. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Can the sealant be colour-matched?
That depends on the product. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.
Is any job too small?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Can you come in just for snagging?
Yes. Share the list and photographs, and a fixed quote follows.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Does the weather affect the work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
When to call us in Tarbert
Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A general-purpose silicone on a facade or a caulk in a wet area won’t perform like the specified product. We stick to the specified product, or put any alternative to you first.
Any of the following is a good reason to get the joints checked over:
- External joints sealed in damp or cold conditions that are now failing
- Window and door perimeters that won’t pass inspection
- Frame gaps too wide for sealant alone
- Caulk cracking where joints are moving more than expected
For a contractor at a hotel such as Hotel Hebrides, less than half a mile to the south-east of Tarbert, the mastic often has to be finished before a reopening date.
What to look for in a quote
- How joint depth will be controlled
- Health and safety accreditation such as CHAS
- Can the work be phased to keep areas open?

Facades, frames and programmes in Tarbert
With the shore within about 1 mile, Tarbert 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, so we check the specified product suits the exposure before the first bead. Building work in Tarbert comes under the Building (Scotland) Regulations 2004 and their technical handbooks, with warrants from the local authority verifier. Our job is to seal to that specification.
Sites around Tarbert get mastic sealed to the drawings and the programme, nothing improvised.

On site: what to expect
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. For work around Tarbert, we aim for one trip, which is why we ask for photographs and a full list first. External joints need a dry spell as well.
- Drawings, specification and programme come to us.
- We take off quantities and return a fixed quote.
- We agree with the site team which areas come first.
- Each area is sealed when it’s released.
- Joints are prepared, backed and sealed to the specification.
- Snags are cleared and the package signed off with our 12-month guarantee.
Getting the site ready
- Send asbestos survey details if the building is pre-2000

Advice
After the work
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Brief following trades on areas that have been sealed
- Record the products used in the O&M file
- Use the product the specification names
- Ask for joint and product checks before the package is urgent
Any damage after we’ve finished should go on the snag list right away. We can return to clear snags before handover as agreed in the quote.
In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Leaks behind showers and basins damage finishes and floors, leaving the remedial work to the contractor. Proper preparation, with the right silicone first time, keeps it off the defects list.
