About our remedial sealant in Hoy
Some sealant jobs are not a simple reseal, because someone has already had a go. New sealant over old, smeared beads, unsuitable products and hidden mould all need stripping out before the joint can be done properly. Typical jobs include black mould underneath the bead and floor or wall movement joints that have failed, across mouldy bath & shower sealant, expansion joints and failed movement joints.
For a place like Hoy, the job is the same as anywhere: everything old is cut out, the joints are cleaned and dried, and new sealant or grout goes in. The journey and access are simply planned in advance.
Every job comes with a 12-month guarantee, wherever you are in the Orkney Islands.

Hoy questions
Will you come out to Hoy?
Yes, we do. We work across all of Scotland, islands included, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you do remedial sealant in Hoy?
Yes, Hoy 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 quote.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
Where are you based?
We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.

Allow a few hours, depending on how many layers have to come out. We’ll give you a timescale when we quote.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us and we are fully insured.
When it isn’t the sealant
Some problems need a builder, plumber or other trade rather than us:
- A tray or worktop that needs refixing first
- A tray or bath that’s cracked
- Water damage behind tiles that needs a tiler
If in doubt, email us at info@mrmastic.co.uk and we will say what we think before booking.
What we seal
- Expansion joints

How the job changes by surface
Mouldy bath & shower sealant
Where mould keeps coming back, ventilation is generally part of the cause. Along with resealing, we’ll mention if the room needs better ventilation.
Movement & expansion joints
A sealant stuck to the back of the joint cannot stretch. Backing stops that, letting the sealant flex between the two faces.
Hoy homes and their sealant
Hoy is within about 1 mile of the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, 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. But mould still grows into sealant and grout in a room that does not dry out.
In and around Hoy, as anywhere, good remedial sealant starts with a clean, dry, properly prepared joint.
Hoy is about 14 miles west of Kirkwall, in the Orkney Islands. Hoy gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. Hoy is one of 51 towns and villages in the Orkney Islands we cover.
Work in KW16 works the same way as everywhere else we cover. You will find Hoy on the B9049, which makes it straightforward to reach with everything needed for remedial sealant. We also cover Stromness (4 miles north), Cairston (5 miles north), Clestrain (5 miles north-east), Midland (5 miles east) and Clouston (6 miles north-east). Island and remote addresses take a little more planning, so tell us where you are when you ask for a quote.
Landmarks near Hoy
Well-known places in the area include Stromness Museum (3.3 miles north). For a walk, there’s Round Hill and South Dam.
What affects the quote in Hoy
There’s no set price list. What we look at:
- How many rooms, windows or areas are involved
- How much old sealant there is and how hard it is to remove
- When we can work, for business premises
- Whether the work is at height
Combining jobs into one visit is generally more efficient than separate visits. We will give you a clear quote for the lot.

- How we’d reach the joints

We do not publish a price list. Instead, your job gets its own clear quote. To arrange one, email us at info@mrmastic.co.uk.
Other services in Hoy
What we are called out for in Hoy
Silicone only bonds to surfaces that are clean and dry. Residue, moisture or dust left in the joint weaken the bond, and the joint starts to come away early.
It’s worth asking for a quote if you see:
- Mould trapped under a layer of silicone
- Torn expansion joints
- A second bead peeling off the first
- Kitchen joints letting water behind the worktop
For jobs in and around Hoy, choosing the right material for each joint is as important as a tidy finish.
Questions to ask before booking
- How much experience the applicator has
- The length of the guarantee
- Whether you can choose the colour
- What the quote includes, VAT included or not
Aftercare tips
Good habits help new joints last longer. A few tips:
- Never seal over old silicone
- Never fill a movement joint with mortar or grout
- Deal with small splits early
- Check trays and worktops don’t move
Keep the room ventilated: use the extractor or open a window after showering.
A failing joint rarely gets better on its own. Each use pushes more water behind the bead, into whatever is behind or below. Early action keeps it to a sealant job.
