DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

Why it’s worth doing now in Sandwick
You do not need a new bathroom because the sealant looks bad. Replacing the joint is usually all it takes, as long as the fittings themselves are sound. If we find a deeper problem, you’ll hear it from us. Around Sandwick, water from a failed joint in an older stone home can soak into timber and plaster.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

Do you work for hotels and guest houses in Sandwick?
Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.

What should I tell you?
Let us know what needs doing and where, with pictures by email if possible. We will ask anything else we need to know.
Is it OK to put new sealant on top of the old bead?
No, and it’s one of the main reasons reseals fail. The old joint is stripped, cleaned and resealed from scratch.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we’re using.

Bathroom resealing in Sandwick: local notes
Sandwick is within about 1 mile of the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, which wears sealant and grout out faster than in a quiet home. Private landlords in Scotland must be registered and meet the Repairing Standard, which includes keeping fixtures and fittings in reasonable repair. Failed sealant around a bath or shower is worth sorting between tenancies.
In and around Sandwick, as anywhere, good bathroom resealing starts with a clean, dry, properly prepared joint. If you live in an older home near Stornoway High Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them.
Sandwick is about 1 mile south-east of Stornoway, in Na h-Eileanan Siar. We carry out bathroom resealing for homes and businesses in Sandwick, as part of our work across Na h-Eileanan Siar. Our area takes in 87 places across Na h-Eileanan Siar, large and small.

Surface by surface
Shower trays & enclosures
There are normally two jobs in a shower: the tray-to-wall joint and the enclosure joints. Both take water every day, so both are resealed with anti-fungal sanitary silicone.
Kitchen worktops & upstands
The joint between worktop and wall takes splashes, crumbs and cleaning sprays. We seal them in a colour that suits the worktop.
What we do, step by step
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take around two hours for one bath or shower, longer for a whole bathroom. Around Sandwick, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- First the area is protected and every bit of old sealant removed, including the film left on the tiles.
- The joint is cleaned, degreased and treated for mould.
- Once it’s dry, any bath is filled so the bead is laid with it at its heaviest.
- A single bead of anti-fungal sanitary silicone is applied and tooled smooth.
- Finally we tidy up and explain the cure time before we leave.
Preparing for the visit
- Mention any tricky access
- Keep children and pets away from the work area
- For indoor joints, keep the area dry beforehand if you can

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Let new sealant cure fully before it gets wet
- Never pick at the silicone with a blade
- Look for lifting corners and small gaps now and then
- Run the extractor fan during and after every shower
Give the silicone time to cure before it gets wet, which is generally around 24 hours. After that, a quick wipe after showering helps keep it clean.
Mould that starts as a few spots spreads through the bead. Once it’s deep in the silicone, cleaning usually will not remove it, and nearby grout often goes the same way. Replacing the sealant early keeps the job small.
