From enquiry to sign-off
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. For a building near Carndu, directions, keys and a contact on the day are worth sorting early. That goes into the plan alongside the quote.
- We price from the drawings, specification and programme you send.
- 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.
- Snags are cleared before handover and completed areas carry our 12-month guarantee.
Before we start on site
- Share the asbestos register for older buildings
- Tell us what induction or permit system the site runs
- Point out any areas we must not close

Construction around smaller Scottish places like Carndu is often one-off schemes: a school, a health centre, a hotel extension or a few houses. The mastic still needs to suit exposed elevations and Scottish weather.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Site staff or a sealant specialist?
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Signs you need construction mastic in Carndu
Value-engineered products sometimes end up in the wrong joints. A general-purpose silicone on a facade or a caulk in a wet area won’t perform like the specified product. We use what’s specified, and any substitute goes to you for acceptance.
Most enquiries start with one or more of the following:
- Frame gaps too wide for sealant alone
- Sanitary sealant damaged by following trades
- Window and door perimeters that won’t pass inspection
- Caulk cracking where joints are moving more than expected
When units on a site such as Ardelve Industrial Estate (to the south-west of Carndu) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
Comparing quotes
- How long is the guarantee, and what does it include?
- Whether primer will be used where the manufacturer specifies it
- Whether their applicators hold CSCS cards
- Will failed sealant be removed rather than covered?
What we can’t put right
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Oversized gaps that need packing or adjustment by others
- Deciding which fire-stopping product a penetration needs
- Joint design decisions that belong to the architect or engineer
If in doubt, speak to us on 01277 525 020 or email drawings and photos and we’ll say what we think.
Joints and surfaces we work on
- Floor and skirting junctions

Aftercare for building managers
Keep the joints in good shape with a few simple steps:
- Brief the final clean team to avoid blades near sealant
- Note which sealant went where at handover
- Check frame gaps are within the sealant’s range before sealing
- Use the product the specification names
Once an area is sealed, protect it from following trades. Fresh sealant needs its cure time before it’s cleaned, painted near or knocked, and that time depends on the product, temperature and joint depth.
External joints sealed in poor weather are a common cause of early failure. Holding off until conditions suit avoids callbacks so external sequencing builds in some flexibility.
Construction mastic in Carndu: the local picture
Carndu lies within about 1 mile of the sea. 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 Carndu follow Scotland’s building regulations, with the local authority acting as verifier. The mastic follows the specification that goes with the warrant.
Hotels like Dornie Hotel (to the south-west of Carndu) rarely close for long, so refurbishment mastic is phased floor by floor.
Carndu is in Highland. Any commercial site in Carndu is covered, whether it’s a single job or part of a planned programme. Our Highland coverage takes in 256 places, from busy centres to rural villages.

Questions we’re asked in Carndu
Is Carndu too far out for you?
No. Small places get the same service as large ones. We work across every Scottish council area. We plan jobs in smaller places so return trips are kept to a minimum.
Can you work at a site such as Ardelve Industrial Estate, by Carndu?
Yes. Our area takes in Carndu and its surroundings, with estates and business parks such as Ardelve Industrial Estate included. Photos and a short description are enough for a first look.
Can you quote from photos?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Can fire-rated sealing at service penetrations be included?
We install fire-rated sealant where it is the specified product, working to the specification and the manufacturer’s installation guidance. If the detail calls for collars, wraps or batts instead, we’ll tell you.
How many days will you need on site?
It depends on the scope, though a typical visit usually takes whatever the programme allows, since the work follows the trades as areas are released. For bigger or phased jobs, we’ll set out a timescale with the quote.
Do you use the sealant named in the specification?
Specification first, then the maker’s instructions. Preparation, backing and depth follow the product guidance.
