About our bathroom resealing in Haroldswick
Kitchens need the same care as bathrooms. The joint between worktop and wall, the edge of the sink and the bottom of the splashback get wet every single day, and water behind a laminate worktop can make it swell. Kitchen joints get a sealant suited to kitchens, colour-matched where it shows. We work on shower trays & enclosures, sinks & splashbacks and basins & vanity units, and common reasons people get in touch are new sealant laid over old sealant that is now lifting and splits where the tray meets the wall.
Bathrooms in smaller places like Haroldswick work just as hard as those in the cities. Limescale is less of a problem with Scotland’s generally soft water, but mould still takes hold in damp sealant and grout.
Each job carries a 12-month guarantee, large or small.

Signs you need bathroom resealing in Haroldswick
Not every tube in the shop is meant for a shower. Decorators’ caulk and all-purpose sealants aren’t made for constant wetting, so they crack, discolour or grow mould quickly. A bathroom joint needs anti-fungal sanitary silicone.
Keep an eye out for these signs:
- New sealant laid over old sealant that is now lifting
- Gaps between the worktop and the wall
- Splits where the tray meets the wall
- Black spots spreading through the bead
If you live in an older home near St John's Church, walls and floors in older homes can move, and sealant and grout show it first.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Surface by surface
Kitchen worktops & upstands
Upstands and back edges are cut out, cleaned of grease and resealed, because cooking grease stops sealant bonding. The extra cleaning is what makes the bead last.
Baths
Baths move more than any other fitting, so we fill it with water before sealing. The joint is then laid with the bath at its lowest point and isn’t stretched when it’s used.
Bathrooms and kitchens in Haroldswick
Haroldswick is close to the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, and sealant and grout that work that hard wear out sooner. In Scotland, private landlords have to meet the Repairing Standard, which covers keeping fixtures and fittings in a reasonable state of repair. Failed sealant around a bath or shower is worth sorting between tenancies.
In and around Haroldswick, as anywhere, good bathroom resealing starts with a clean, dry, properly prepared joint.

Your questions about bathroom resealing in Haroldswick
What guarantee comes with bathroom resealing in Haroldswick?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Is Haroldswick within the area you cover?
Yes, we do. Our work covers the whole of Scotland, islands included, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply send an email to info@mrmastic.co.uk.
Do you do kitchens as well as bathrooms?
Yes, often alongside a bathroom. Next to the sink we use a food-safe product where it’s needed.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Can new silicone go straight over the old?
No, never. Sealing over the top looks fine for a few weeks, then lifts, because silicone does not bond to silicone. Every trace of the old bead is removed first.
How long does a bath or shower reseal take?
It depends on how many joints there are and how much old sealant has to come out. For most single baths or showers, allow a couple of hours.
How the visit works
When we arrive, we look over the joints with you first, so you know exactly what we’re doing. We protect the surfaces around the joints before any work begins. The work usually takes two to three hours for a typical bath, depending on how much old sealant there is. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- Protection goes down around the bath, shower or worktop.
- Old sealant is sliced away and the residue removed.
- We treat any mould and let the joint dry properly.
- Any bath is filled with water, then we lay a bead of anti-fungal silicone in white, clear or a matching colour.
- The joint is finished neatly and we explain when it can get wet.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Tell us about any water getting in
- Tell us about any previous sealing or DIY attempts

How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Never pick at the silicone with a blade
- Wipe the sealant dry after showering
- Stick to a soft cloth and a mild cleaner
- Run the extractor fan during and after every shower
Mould needs damp, so keep the room aired. Run the extractor fan during and after a shower, so the bead dries out between uses.
Each shower pushes a little more water through a failed joint. Over time that water reaches floors, walls and ceilings. Resealing early stops it.
What affects the cost of bathroom resealing
There’s no set price list. What we look at:
- The old material and how stubborn it is
- Access and height
- Whether there’s mould to deal with
- The size of the job
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
What to tell us for a quote
Photos help, but a description is a good start. Try to tell us:
- The address or postcode of the job
- Roughly how big the job is
- A few pictures by email, if you can
- Access, such as stairs, a lift or height
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. When it suits you, drop us a line at info@mrmastic.co.uk.
