What the job involves on each surface
Snagging before handover
The last pass before handover is where mastic snags are cleared. Snags are cleared room by room.
Kitchens and utility areas
Commercial kitchens often need hygienic or food-safe sealants. Joints are sealed smooth so they’re easy to clean.
How we handle construction mastic in Lewiston
External mastic depends on the weather in a way most internal trades don’t. Cold or damp mornings, frost and condensation on frames can all hold external sealing up so it helps to sequence elevations with some flexibility. Internal areas can typically carry on while the outside waits. Most enquiries involve failed sealant in an existing building being refurbished and sealant knocked or painted over by other trades, across floor and skirting junctions, brick and block movement joints and sanitary and kitchen joints. Most enquiries from Lewiston start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Sites near smaller places like Lewiston can mean longer travel, so the mastic is planned with as few trips as the job allows. Clear drawings, a programme and photographs let us bring the right sealants, primers and backing rod first time.
Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

New build and refits around Lewiston
In Lewiston, as across Scotland, building warrants are issued by the local authority verifier under the Scottish regulations. The mastic follows the specification that goes with the warrant. There are several hotels within about 2 miles of Lewiston. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
Historic houses such as Boleskine House, 4.4 miles to the south of Lewiston, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. School extensions, at buildings such as Glen Urquhart High School, normally run to the summer holidays, mastic included. For a contractor at a hotel such as Benleva Hotel, under half a mile to the north-east of Lewiston, the mastic often has to be finished before a reopening date.
Lewiston is about 13 miles south-west of Inverness, in Highland. Lewiston sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. Our Highland coverage takes in 256 places, from busy centres to rural villages.

When something else is needed
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Faulty frames rather than failed sealant
- Rework caused by others damaging completed areas
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)

What else we do in Lewiston
Diagnose, treat, sign off
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes whatever the programme allows, since the work follows the trades as areas are released, and we clear our waste as we work. Travel to smaller Scottish places like Lewiston is planned so the job is finished in one visit where possible, which is why we ask for photos and a full list first. 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.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- Work follows the programme, area by area, as rooms and elevations become ready.
- Every joint is prepared, set to depth and sealed with the specified product.
- Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.
Before we start on site
- Send any specification or drawings in advance
- Send your site hours and access windows
- Point out any areas we must not close

FAQs: Lewiston
Which documents can you supply for work in Lewiston?
RAMS, insurance certificate, CSCS details: list what the site needs and we will confirm it with the quote. We are CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.
Is a smaller place like Lewiston outside your area?
No. Small places get the same service as large ones. Our area covers all of Scotland, cities, towns and islands alike. Where we can, we group nearby jobs to make the most of each trip.
Can you come in just for snagging?
Yes. We can work through a mastic snag list area by area before handover.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
What if there’s asbestos in the old mastic?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
How much does the work cost?
We don’t publish prices, as every site differs. Send photographs or drawings and we will price it at a fixed figure.
Are you CHAS accredited?
We are CHAS accredited and a Constructionline member, and our applicators hold CSCS cards. Public liability insurance is in place.
Looking after the joints
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Note which sealant went where at handover
- Check frame gaps are within the sealant’s range before sealing
- Bring the mastic contractor in after the last trades are through
- Put any product change through the designer first
After we’ve sealed an area, it helps to keep other trades from damaging the joints. New beads should be left to cure before cleaning or decorating nearby, and that time depends on the product, temperature and joint depth.
Sealing outside when the joint is damp or too cold leads to poor adhesion. Waiting for a dry joint and the right temperature is better than redoing work so external sequencing builds in some flexibility.
