About our bathroom resealing in Gunnista
A reseal only lasts if the joint is properly prepared. Every bit of old silicone comes out, down to the thin film left on the tiles, then the joint is cleaned, degreased and treated for mould. New silicone goes on only when the joint is fully dry. We’re often asked to deal with leaking joints on a shower screen and damp behind the bath or under the tray, across kitchen worktops & upstands, baths and basins & vanity units.
For a place like Gunnista, the job is the same as anywhere: old material out, joints cleaned and dried, and a fresh, even finish. The journey and access are simply planned in advance.
Each job carries a 12-month guarantee, whatever its size.

What bathroom resealing looks like in Gunnista
Gunnista is within about 1 mile of 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. Scottish Water supplies are generally soft, so limescale is less of a problem than in hard-water areas. But mould still grows into sealant and grout in a room that doesn’t dry out.
In the older streets around St Ola's Church and burial-ground, older homes can move a little, which is hard on rigid grout and tired sealant.
Gunnista is in the Shetland Islands. Our applicators cover bathroom resealing for homes and businesses in Gunnista and the surrounding area, as part of our work across the Shetland Islands. Our the Shetland Islands coverage runs to 63 places, and Gunnista is one of them.

Aftercare tips
Good habits help new joints last longer. A few tips:
- Wipe up water along the back of the worktop
- Keep the fan on for a while after bathing
- Avoid abrasive pads on the sealant
- Squeegee the walls and tray after use
Keep water off the new bead until it has cured, following the cure time we give you. After that, a quick wipe after showering helps keep it clean.
A split bead lets water through every time the bath or shower is used. Left alone, it soaks into the floor, the wall behind the tiles or the ceiling below. Resealing early stops it.
Surface by surface
Shower trays & enclosures
Shower trays are sealed to the wall, and enclosures are sealed to the tray and tiles. Both get soaked every time the shower runs, so both are resealed with anti-fungal sanitary silicone.
Kitchen worktops & upstands
Laminate worktops swell if water gets into the core. A sound joint along the back edge stops that, as long as the worktop itself is firmly fixed.

Common questions in Gunnista
Is Gunnista in your area for bathroom resealing?
Yes, Gunnista is within the area we cover. Our work covers the whole of Scotland. You can email us at info@mrmastic.co.uk and tell us what needs doing, and we’ll give you a clear price.

How much does bathroom resealing cost in Gunnista?
Every job is different, so each one gets its own quote. For a quick quote, send an email to info@mrmastic.co.uk and tell us what needs doing and where.
Is there any odour?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Can mouldy silicone be sorted out?
Yes. Mould inside the bead rarely cleans out for good, so we cut it out, treat the joint and reseal with anti-fungal silicone.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
What do you need from me for a quote?
The location, the problem and the rough size of the job. Photos by email help too.
Can you just seal over the old silicone?
No, never. Sealing over the top looks fine for a few weeks, then lifts. We remove the old bead completely before resealing.
What we’re called out for in Gunnista
Sealant laid on a damp, dusty or greasy joint never bonds properly. Soap residue, oils and leftover silicone film all get in the way, and a joint that looked fine soon begins to come away.
Any of these means the joints need attention:
- Water getting behind the bath panel
- Water escaping at the shower enclosure
- Shrunken sealant along the back of a worktop
- A bead that has pulled away from the tiles
Schools such as Anderson High School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.

DIY versus a professional finish
If you do try it yourself, take your time over the 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.
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.
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
How we quote for bathroom resealing
The price is agreed before any work begins. It’s based on:
- Whether there’s mould to deal with
- How much old sealant there is and how hard it is to remove
- Access and height
- The number and length of the joints
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What we need to know
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- How we’d reach the joints
- A few photos by email, if you can
- Whether it’s a home or a business
- Where the job is, and your postcode
Asking for a quote is easy: let us know the job and the location. A few photos by email make the job easier to understand, and we will take it from there.
What happens on the day
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes half a day or less for one room, longer when the kitchen is included. Outside jobs in Gunnista need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- We cover the area around the joints we’re working on.
- We cut away the old sealant and clean off what’s left.
- We treat any mould and let the joint dry properly.
- Baths are filled first, then anti-fungal sanitary silicone is applied in a colour to suit.
- We finish the joint, clear up and tell you how long to leave it before it gets wet.
Preparing for the visit
- Clear items away from the joints we’re working on
- Mention any leaks or damp you’ve noticed
- Where the joints are inside, avoid wetting them before we arrive
