Isbister Remedial Sealant
Specialist remedial sealant for Isbister: the right sealant, proper preparation and a neat finish. Call for a quick quote.
- Products that weren’t meant for the joint
- Movement joints that have split or pulled away
- A shower that leaks however often it’s resealed
Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
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.
Remedial sealant for homes and businesses in Isbister
If a joint has been resealed and is leaking again, it’s worth a proper look. Send pictures when you email us at info@mrmastic.co.uk, and say how long ago it was last done. Common call-outs are for caulk or the wrong sealant used in a wet area and dark patches showing through the sealant, across botched or over-sealed joints, leaking tray & enclosure joints and failed movement joints.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses. Where a building moves, cracked grout and split sealant are normally the first signs.
Every job comes with our one-year guarantee, wherever you are in the Orkney Islands.

Leave it or put it right?
It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and the residue left behind stops the next bead bonding. Careful removal is most of a remedial job. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Why book with us
- Domestic, commercial and hotel work
- Old sealant always removed completely
- Colour agreed with you before we start
- ARBOMaster approved applicator
When to call us in Isbister
A lot of failed joints have been sealed over rather than replaced. New silicone can’t stick to the old bead, so the top layer lifts and water and mould collect between the two.
Common reasons people contact us include:
- Smears and lumps from a botched reseal
- Worktop sealant that has shrunk and split
- Sealant peeling off a dusty or damp surface
- A second bead peeling off the first
Around Isbister, as everywhere, remedial sealant is only as good as the preparation behind it.
Questions to ask before booking
- Is the old sealant removed completely?
- Whether they’re fully insured
- Is VAT in the price?

Remedial sealant in Isbister: local notes
Isbister 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.
Whether the job is in Isbister itself or nearby, the right material for each joint matters as much as a neat finish.
Isbister is about 6 miles north-west of Kirkwall, in the Orkney Islands. From the centre of Isbister to the outskirts, remedial sealant is available for homes and businesses alike. Our area takes in 51 places across the Orkney Islands, from the larger towns to small villages.

Honest limits
New sealant can’t fix everything, and we’ll tell you before work begins. Sealant will not put right:
- A cracked shower tray or bath (that needs repair or replacing)
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- Water damage behind tiles that needs a tiler

Isbister questions
Is Isbister in your area for remedial sealant?
Yes, Isbister is within the area we cover. Our work covers the whole of Scotland. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing, and we’ll give you a clear price.
Is there a guarantee on remedial sealant in Isbister?
All our work, in Isbister and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Do you fix expansion and movement joints?

Can I add another job to the visit?
Yes. More than one area can go on one quote.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
What should I tell you?
A short description and the location. We’ll ask anything else we need to know.
Do you work for letting agents?
Yes, often. We can quote for several properties at once, and between tenancies is a good time for the work.
Where do you work from?
We work from Crawley. Our applicators cover Isbister.
How to look after the new joints
To keep the joints looking good and working properly:
- Deal with small splits early
- Check ceilings under showers for marks
- Get the cause of a repeat leak found before resealing
- Don’t add new sealant on top of old
Ventilation keeps mould away from the new bead: use the extractor or open a window after showering.
Leaks through failed sealant grow over time. Every shower or downpour sends more water through, into floors, walls or ceilings. Early action keeps it to a sealant job.
