Remedial sealant & repairs in Blackhill, Orkney Islands
Remedial sealant across Blackhill and nearby, with old sealant always removed completely and a one-year guarantee.
- Leaks that keep coming back after resealing
- Gaps opening along the back of the worktop
- Floor or wall movement joints that have failed
Surface by surface
Worktops & kitchens
Kitchen joints often have grease and cleaning residue deep in them, so cleaning takes longer than in a bathroom before resealing.
Leaking trays & enclosures
A cracked tray, failed valve or leaking waste needs a different fix. We say so rather than reseal.
Remedial sealant for homes and businesses in Blackhill
A movement joint stops working when its sealant splits or sets hard. We cut out the failed sealant and set the depth with backing, then a flexible sealant matched to the movement goes in. We work on botched or over-sealed joints, mouldy bath & shower sealant and expansion joints, and common reasons people get in touch are products that weren’t meant for the joint and beads that never stuck properly.
In and around a place like Blackhill, homes range from older stone-built properties to newer houses. Where a building moves, cracked grout and split sealant are normally the first signs.
A one-year guarantee comes as standard.

How the visit works
All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours, depending on how many layers have to come out. Outdoor work around Blackhill depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- First we work out whether the problem is the sealant, movement or a leak.
- Each layer is cut out and the residue cleaned off.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you’re told about anything else we found.
Before we arrive
- Mention if the joints have been sealed before
- Tell us about any water getting in
- Tell us about access, such as stairs, a lift or high-level joints

Remedial sealant around Blackhill
Blackhill is close to 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. Island jobs need planning around ferries and the weather, so give us as much notice as you can.
In and around Blackhill, as anywhere, good remedial sealant starts with a clean, dry, properly prepared joint. Whether the job is in Blackhill itself or nearby, the right material for each joint matters as much as a neat finish.

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Do not point over movement joints
- Run the fan after every shower
- Find out why the sealant failed first
- Have loose fittings fixed before resealing
Ventilation keeps mould away from the new bead: use the extractor or open a window after showering.
A split movement joint lets rain into walls and floors, and the longer it’s left, the more the joint edges break down. A joint with sound edges is far easier to reseal.

Questions from Blackhill
Can you do remedial sealant in Blackhill?
Yes. We work across all of Scotland, and Blackhill is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear price.
Do you cover smaller places like Blackhill?
Yes, smaller places are covered as well as towns. Our work covers the whole 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.
Which products do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Can you fix a reseal that hasn’t worked?
Yes. Repeat leaks normally come from over-sealing, movement or water getting in elsewhere, and we deal with the cause first.
Can tenants book the work?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Are you fully insured?
Yes, we’re fully insured for every job we do.
Do you guarantee remedial jobs?
Yes. Our 12-month guarantee covers the work, and we are fully insured.
What sealant work can’t fix
It helps to know what we cannot do:
- Plumbing leaks behind walls or under trays
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- Movement from fittings that aren’t supported
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think before booking.
What we seal
- Failed movement joints
- Mouldy bath & shower sealant
- Botched or over-sealed joints
- Shrunken worktop sealant
- Expansion joints
- Leaking tray & enclosure joints
DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
