Sealant on show in Gelston’s commercial buildings
Being in the east of Scotland, Gelston gets less rain than the west coast. Cold snaps still affect when external joints can be sealed. In winter, outside joints are timed for when surfaces are dry and within the product’s range
Where a joint is on show in Gelston, we’ll check which shades the product offers before work starts.

Commercial sealant contractors for commercial buildings in Gelston
Commercial occupiers rarely want a floor out of action for sealant work. Work is scheduled around the site hours and access windows you give us. It’s the same approach in offices, retail units, hotels, schools and healthcare buildings. If you have water staining near frames, panels or ceilings and movement joints packed with grit and debris, we can put it right, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, in Gelston it comes down to the same thing: the right product in a properly prepared joint.
The most common commercial job in Gelston is resealing joints that have simply reached the end of their life: split, chalky or peeling, with leaks or mould starting behind it.
For work in and around Gelston, we’d rather do everything on one trip, so it helps to have photographs and a full list first. Several jobs nearby can also be put together.
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.

When to call us in Gelston
No sealant joint is permanent. Its life comes down to movement, UV and weather, how it’s cleaned, how much traffic passes it and what was used in the first place. In commercial buildings those factors tend to act together.
Typical triggers for a call:
- Shrunken sealant along kitchen worktops and splashbacks
- Black mould through washroom sealant that won’t clean off
- A top-up bead over failed sealant, now lifting
- Expansion joints with the sealant torn out
For any commercial premises in Gelston, a lasting joint depends on full removal of the old sealant and clean, dry faces.
Before you book anyone
- How they handle RAMS and site documents
- Their approach to joint depth and backing
- Whether primer will be used where the manufacturer specifies it
- What level of public liability insurance do they hold?
Why deal with it now?
Spot repairs have their place. If the rest of the bead is the same age and product, though, it’s usually close behind, and a second visit means paying for access and set-up again. We can price both options so you can decide on the facts. In Scotland, wind-driven rain finds a failed joint quickly, so it’s worth renewing joints around Gelston before they leak.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
Why appoint us
- 12-month guarantee on workmanship
- Colour options checked against the specified product
- RAL and finish matching where the product range allows
- CHAS accredited

Aftercare for building managers
To get the most from the new sealant:
- Keep washroom and kitchen extraction working
- Act on the first lifting edges rather than waiting
- Brief cleaning contractors to avoid scourers and blades on sealant
- Check joints after other trades have worked nearby
In washrooms and kitchens, extraction makes a real difference to sealant life. Fans that are broken or switched off leave joints damp for longer, which is how mould gets back in. It’s worth having fans checked while the sealant is fresh.
Sealant rarely fails all at once across a building. A few splits this year normally mean more next year. We will tell you which sealant joints need doing first and which can wait.
Common questions from Gelston clients
Is Gelston too far out for you?
No. Small places get the same service as large ones. Our area covers all of Scotland, cities, towns and islands alike. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
What documents will you need to give us for a job in Gelston?
RAMS, insurance certificate, CSCS details: list what the site needs and we’ll confirm it with the quote. We’re CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators, as many construction sites ask for.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
What guarantee do you give on resealing?
Our workmanship on each job is backed by a 12-month guarantee. We are fully insured for public liability as well.
Is the old sealant taken out first?
Removal comes first, every time. Then the joint is cleaned, primed where the maker specifies, backed to depth and resealed.
On site: what to expect
On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work typically takes a few hours for one area, or a planned series of visits across a bigger building. For work around Gelston, we aim for one trip, which is why we ask for photos and a full list first. Outside work also needs a suitable weather window.
- You send photographs, drawings or a list of the joints and areas involved, or we arrange a site visit.
- The failure is diagnosed and a fixed quote issued for the work agreed.
- Site hours, access windows and the order of areas are agreed before we start.
- The failed bead is removed and the joint faces cleaned until they’re sound and dry.
- We fit backing to the right depth, prime where specified and lay the new bead.
- Finished joints are checked with you and handed over with our 12-month guarantee.
What we need from you
- Tell us your opening times and when work is allowed
- Let building users know which areas are affected
- Make sure the joints can be reached

Different surfaces, different methods
Shop fronts and retail fit-outs
Retail work typically has to fit around trading. We plan around the access windows the store gives us, working in sections where that helps.
Washrooms and toilets
Around WCs, urinals, vanity tops, IPS panels and cubicles, sealant is wet most of the day. We cut out mouldy or split beads and reseal in anti-mould sanitary silicone, with phased work so some facilities stay open.
Commercial clients in Gelston
Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so the building keeps working while we do.
As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
