How we handle construction mastic in Tarbet
Refurbishment work needs a slightly different approach from new build. Old beads come out completely, as fresh silicone can’t grip old and the asbestos survey is checked first on older stock. New and existing joints then get the same preparation. Most enquiries involve sanitary sealant damaged by following trades and caulk cracking where joints are moving more than expected, across internal decorators’ caulk, cladding and panel joints and sanitary and kitchen joints. A single leaking joint is often how a building in Tarbet first comes to us: we look at the rest while we’re there and tell you what we find.
External sealing around Tarbet depends on dry faces and the right temperature. We build some give into the plan and agree it with the site manager.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Different surfaces, different methods
Window and door perimeters
Frames sealed into the opening keep rain out of the reveal. We use the specified perimeter sealant, normally a low-modulus neutral-cure silicone.
Kitchens and utility areas
Kitchen joints are sealed after fitting and before final clean. A kitchen-suitable sealant is used, food-safe where food contact is possible.
Your questions answered
Will you fit the mastic around our build programme in Tarbet?
Yes. Send the programme and drawings, and we’ll plan the mastic to suit the stages. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Can being near the sea in Tarbet affect the sealant we need?
It can. Coastal exposure works external joints harder than inland weather. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
How many days will you need on site?
That varies with the scale of the job, though a typical visit normally takes a few days on a modest refurbishment and longer on multi-plot or multi-storey schemes. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Do you do internal caulk as well as external mastic?
The scope comes from the specification and drawings, but most packages include frame perimeters, sanitary and kitchen joints, caulking where specified and a snagging pass.
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.
What guarantee comes with a mastic package?
It carries a 12-month guarantee on our workmanship. We are also fully insured for public liability.
From enquiry to sign-off
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Where we can, we combine work around Tarbet with other jobs nearby. Tell us how flexible your dates are.
- First we look at the scope on site or from drawings.
- You receive a fixed quote covering scope, products and sequence.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- We seal plot by plot or floor by floor in line with the programme.
- Problems we find, such as oversized gaps, are raised right away.
- Final snagging is completed and the 12-month guarantee applies.
What we need from you
- Explain the parking and delivery arrangements
- Point out any areas we must not close
- Clear stock, furniture or equipment away from the joints

Advice
What we can’t put right
Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:
- Frames fitted out of tolerance
- 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)
Not sure which it is? You can phone 01277 525 020 or email us and we’ll tell you honestly.
Surfaces we seal
- Window and door perimeters
- Floor and skirting junctions
- Cladding and panel joints
- Internal decorators’ caulk
- Sanitary and kitchen joints
- Brick and block movement joints
Why deal with it now?
Getting the mastic contractor involved early pays off. Early involvement means gaps, products and access are sorted before the programme bites. Leave it late and they turn up on the snag list. Around smaller places like Tarbet, halls, stores and seasonal buildings may not be checked often, giving water time to get in. Resealing early avoids that.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

Common problems we fix in Tarbet
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.
What tends to prompt an enquiry:
- Missed perimeter joints on a new elevation
- Existing joints on a refurb that need cutting out and resealing
- Snag items on joints that need redoing before handover
- Inconsistent sealant finishes from plot to plot
For contractors building in or near Tarbet, we seal to the drawings, the specification and the programme.

Construction mastic in Tarbet: the local picture
Tarbet is within about 2 miles of the coast. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, so we check the specified product suits the exposure before the first bead. Scotland has its own building regulations, and in Tarbet warrants come from the local authority verifier. Our job is to seal to that specification.
Work at a hotel such as Tarbet Hotel (to the east of Tarbet) tends to be programmed around bookings, mastic included.
