How the job changes by surface
Washrooms and toilets
Washroom joints take water, cleaning chemicals and constant use. Old sealant comes out and a sanitary silicone with anti-mould additives goes in, with phased work so some facilities stay open.
Shop fronts and retail fit-outs
Shop fits put sealant right in front of clients. Joints around counters, displays and shopfront frames have to look tidy as well as seal, frequently colour-matched to the fit-out. Colour options are confirmed with the quote.

- Next comes a diagnosis and a fixed quote.
- We plan around your site hours and access windows, phasing the work where areas have to stay in use.
- Failed sealant is cut out and each joint cleaned back to sound, dry faces.
- We fit backing to the right depth, prime where specified and lay the new bead.

Frontages, fit-outs and joints in Rhu
Rhu lies within about 1 mile of the sea. Exposed frontages near the sea are hard on sealant, so the product has to suit the weather as well as the look. We choose a product rated for the exposure, then confirm the colours available for it. Several hotels sit less than 2 miles from Rhu. A hotel refurbishment is full of joints that guests will see, and a matched colour keeps them discreet, and the work can be phased so the rest of the hotel keeps trading.
Premises within reach of Helensburgh Upper station (1.9 miles east of Rhu) often have busy frontages where joints are seen by everyone passing.

Common problems we fix in Rhu
The wrong sealant in the wrong place is a common cause of early failure. Painters’ acrylic in a moving joint, vinegar-smelling silicone on metal or natural stone, or a high-modulus product where a low-modulus one was needed will all fail early. Guidance such as BS 6213 exists to steer sealant selection for exactly this reason, and many specifications refer to it.
Clients normally get in touch after noticing something like this:
- Mouldy silicone around WCs, urinals and vanity tops
- Water staining near frames, panels or ceilings
- Expansion joints with the sealant torn out
- Weathered facade sealant that no longer flexes
Refits at hotels like Rosslea Hall Hotel, less than half a mile to the south-west of Rhu, bring joints at vanity tops, bars and reception desks that guests see every day.

Keeping the joints sound
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Have extract fans checked so wet areas dry out
- Don’t let cleaning or traffic back on before the cure time is up
- Check the asbestos register before anyone disturbs old sealant in an older building
- Add sealant to the planned maintenance inspection list
Put sealant on the planned maintenance checklist. Regular checks pick up small failures before they become leaks, especially on exposed elevations and in washrooms. Should something look amiss, you can ring 01277 525 020 or email drawings and photos and send a picture.
Sealant rarely fails all at once across a building. The first failures are often a warning about the rest. We can assess the lot and suggest what to do now and later.
Questions we are asked in Rhu
Can being near the sea in Rhu affect the sealant we need?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Will our hotel in Rhu need to close for the work?
In most cases no closure is needed: we work room by room or floor by floor. The plan is built around your bookings.
How long before the joints can be used?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
Do you seal on top of existing sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Are you CHAS accredited?
Yes. We are CHAS accredited and a Constructionline member.
How many days will you need on site?
That varies with the scale of the job, but the work normally takes anything from part of a day on a short run of joints to several weeks on a large phased package. Larger or phased jobs take longer, and we will give you a timescale with the quote.
When is resealing likely to be due?
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.

Other services in Rhu
For managing agents and facilities managers
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
Why act early in Rhu
Sealant is often treated as an afterthought by the trade that fitted the element. A specialist applicator takes care of product choice, joint depth and preparation, the three things that decide how long a joint lasts. It shows over the following seasons rather than at handover. Renewing every failing joint on one visit is the sensible approach for a place like Rhu. Photos of each area help us quote the whole job.
The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.
