Remedial sealant & repairs in Gulberwick, Shetland Islands
Removing failed, mouldy or leaking sealant and putting it right for Gulberwick, backed by a 12-month guarantee. Call for a quick quote.
- Kitchen joints letting water behind the worktop
- Sealant applied over old sealant that has lifted
- Decorators’ caulk around a bath or shower
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Use a soft cloth, not a scourer, on silicone
- Keep the room well ventilated
- Never seal over old silicone
- Do not wait for a small gap to become a leak
Do not let anyone seal over it later. Over-sealing is how many remedial jobs start.
Warning signs: sealant lifting at the ends, a second bead visible on top of the first, black mould under the silicone, or stains below a bathroom. Each one is worth getting looked at.
About our remedial sealant in Gulberwick
Removing failed sealant is the hardest part of the job. Every layer is cut out, the residue cleaned off and the joint degreased, without scratching tiles, trays or frames. New sealant only bonds to a clean, dry joint. We work on botched or over-sealed joints, leaking tray & enclosure joints and failed movement joints, and people most often call us about over-sealed joints coming away and smears and lumps from a botched reseal.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses. Older buildings can move a little, and that shows first in cracked grout and split sealant.
Your job is guaranteed for a year, as with all our work.

Remedial sealant in Gulberwick: local notes
Gulberwick 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, and sealant and grout that work that hard wear out sooner. Private landlords in Scotland must be registered and 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.
If you live in an older home near Gulberwick Mission Church, walls and floors in older homes can move, and sealant and grout show it first. In and around Gulberwick, as anywhere, good remedial sealant starts with a clean, dry, properly prepared joint.

Leave it or put it right?
Leaks that are left keep doing damage out of sight: soaked floorboards, ceiling stains below and blown plaster. By comparison, sorting the joint is quick. Around Gulberwick, water from a failed joint in an older stone home can soak into timber and plaster.
Combining jobs into one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

Gulberwick questions
Is Gulberwick in your area for remedial sealant?
Yes. Our work covers the whole of Scotland, and Gulberwick is part of that. You can send an email to info@mrmastic.co.uk and let us know what needs doing, and we will give you a clear price.
Is there a guarantee on remedial sealant in Gulberwick?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Can you remove sealant that’s been put over old sealant?
Yes. Each layer is cut out and the residue cleaned off, then the joint is resealed once.
Will the old sealant be removed?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we are using and why.
What does remedial sealant cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we’ll talk you through it.
Can you remove old sealant without damaging the bath?
Yes. We take our time over removal, particularly on softer surfaces like acrylic.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Work for landlords, hotels and businesses
We also work for property managers and facilities teams in Gulberwick and across the Shetland Islands. We can quote a run of properties together, and we’re fully insured.
If you manage several properties in or around Gulberwick, several properties can be quoted together. Send us the addresses and the work at each, and photos by email help.
What sealant work can’t fix
It helps to know what we can’t do too:
- Plumbing leaks behind walls or under trays
- A tray or bath that is cracked
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think before booking.
Where we work in Gulberwick
- Shrunken worktop sealant
- Expansion joints
- Leaking tray & enclosure joints
- Failed movement joints
- Botched or over-sealed joints
- Mouldy bath & shower sealant
How it works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a typical bath or shower, longer where several layers have been applied, and the area is left clean. Outside jobs in Gulberwick need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- New sealant goes in once the joint is dry, and is tooled smooth.
- You get the cure time and our view on why the joint failed.
Before we arrive
- Try not to wet indoor joints just before the visit
- Clear the area around the work
- Mention any sign-in or site rules at work premises
