About our remedial sealant in Upper Sanday
Removing failed sealant is the hardest part of the job. We cut out every layer, clear the residue and degrease the surfaces, without scratching tiles, trays or frames. New sealant only bonds to a clean, dry joint. We work on leaking tray & enclosure joints, failed movement joints and botched or over-sealed joints, and common reasons people get in touch are smears and lumps from a botched reseal and products that weren’t meant for the joint.
Being further from a city does not change the work: everything old is cut out, the joints are cleaned and dried, and new sealant or grout goes in. We just plan the journey and access beforehand.
Your job is guaranteed for a year, as with all our work.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
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.
Why deal with it now?
Adding more sealant is the usual quick fix, and it rarely works. It cannot bond to what’s underneath, so the leak carries on and there’s now more to remove. In an older home around Upper Sanday, damp from a failed joint can get into timber and plaster.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, send an email to info@mrmastic.co.uk for an honest opinion and a quote.

Do you need remedial sealant in Upper Sanday?
Some joints fail because water is reaching them from behind. A leaking valve, a failed waste or cracked grout feeds water behind the bead, so the silicone goes mouldy or lets go.
Most people get in touch after spotting one of these:
- Decorators’ caulk around a bath or shower
- Gaps opening along the back of the worktop
- Sealant peeling off a dusty or damp surface
- Thick, messy sealant smeared over tiles
In and around Upper Sanday, as anywhere, good remedial sealant starts with a clean, dry, properly prepared joint.

The process
On the day, we look over the joints with you first, so you know exactly what we are doing. We protect the surfaces around the joints before any work begins. The work normally takes a few hours for a typical bath or shower, longer where several layers have been applied. Outside jobs in Upper Sanday 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 isn’t affected.
- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- The joint is degreased and checked for movement and leaks.
- New sealant goes in once the joint is dry, and is tooled smooth.
- We give you the cure time and explain what caused the failure.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- On commercial sites, let us know about site rules
- Mention any leaks or damp you’ve noticed

Advice
Questions from Upper Sanday
Is Upper Sanday within the area you cover?
Yes. Upper Sanday is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland, including the islands, where work is planned around ferry crossings. Let us know about access, parking and anything unusual about getting there when you book.
Is there a guarantee on remedial sealant in Upper Sanday?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Can old silicone be taken off without scratching the tiles?
Yes. We cut and lift the old sealant with tools suited to the surface, then clean off the residue. We point out any damage that is already there.
Where is Mr Mastic based?
We are a Crawley-based firm. We work across South East England, London and Scotland.
Can landlords and businesses book you?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels across the Orkney Islands.
Can you fix a reseal that hasn’t worked?
Yes. Repeat leaks normally come from over-sealing, movement or water getting in elsewhere, so we find that first.
Will there be a smell?
Possibly a little. It fades as the sealant cures.
Can you take off two layers of silicone?
Yes. Stripping layered sealant takes longer than a normal reseal, but it’s the only way the new joint will last.
What affects the quote in Upper Sanday
The quote reflects the job in front of us. We look at:
- Which sealant suits the joint
- Whether old sealant or filler has to be cut out
- The number of rooms or windows
- When we can work, for business premises
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
What to tell us for a quote
You don’t need to know the technical terms. Just tell us:
- Whether it’s a home or a business
- Access, such as stairs, a lift or height
- How many joints, rooms or windows are involved
- What’s wrong with the joints now
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, send an email to info@mrmastic.co.uk.
How to look after the new joints
Good habits help new joints last longer. Our tips:
- Keep an eye on the ceiling below the bathroom
- Have loose fittings fixed before resealing
- Get the cause of a repeat leak found before resealing
- Don’t wait for a small gap to become a leak
Give the new sealant its full cure time: normally around 24 hours, or as long as we advise.
Do not keep resealing the same joint. Have someone find out why, or the next bead will go the same way.
Bathrooms and kitchens in Upper Sanday
Upper Sanday 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. Scotland’s water is generally soft, so sealant and grout see less limescale than in much of England. Mould is another matter: a bathroom that stays damp still turns sealant and grout black.
Whether the job is in Upper Sanday itself or nearby, the right material for each joint matters as much as a neat finish.
