Widewall Remedial Sealant
We cover Widewall for removing failed, mouldy or leaking sealant and putting it right. Old material cut out, joints cleaned and sealed neatly.
- Gaps opening along the back of the worktop
- Repeat leaks from the same joint
- Mould trapped under a layer of silicone
Remedial sealant in Widewall
If a joint has been resealed and is leaking again, it’s worth a proper look. Send photos when you email us at info@mrmastic.co.uk, along with when it was last resealed. We work on expansion joints, shrunken worktop sealant and leaking tray & enclosure joints, and common reasons people get in touch are mould trapped under a layer of silicone and wide, uneven beads that look worse than the old ones.
For a place like Widewall, 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. We just plan the journey and access beforehand.
Big or small, it’s backed by our 12-month guarantee.

Remedial sealant around Widewall
Widewall is close to the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, and sealant and grout that work that hard wear out sooner. Work on the islands has to be planned around ferry crossings and the weather, so the more notice, the better.
Whether the job is in Widewall itself or nearby, the right material for each joint matters as much as a neat finish.
Widewall is about 12 miles south of Kirkwall, in the Orkney Islands. Across the KW17 area, our applicators can take on remedial sealant. Our area takes in 51 places across the Orkney Islands, from the larger towns to small villages.
All of KW17 is covered for remedial sealant, from the main roads to the quietest streets. With the B9042 close by, Widewall is easy for our applicators to reach for remedial sealant. We also cover the places around Widewall: St Margaret's Hope (2 miles north-east), Grimness (3 miles north-east), Burray Village (4 miles north-east), St Mary's (7 miles north) and Lyness (8 miles west). If you are somewhere remote, the job takes a little more planning.

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Keep the room well ventilated
- Never seal over old silicone
- Clean sealant with mild products only
- Find out why the sealant failed first
Keep an eye on the joint at first, particularly where the original failure was caused by movement. Should anything change, send an email to info@mrmastic.co.uk.
Movement joints that have split let water into the structure, and the longer it’s left, the more the joint edges break down. Resealing while the edges are sound is simpler.
What affects the cost of remedial sealant
There’s no set price list, because no two jobs are the same. What we look at:
- Any working-time requirements on site
- How much there is to do
- The product the joint needs
- Whether there’s mould to deal with
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.
Asking for a quote
To help us quote quickly, let us know:
- What’s wrong with the joints now
- Access, such as stairs, a lift or height
- Photos by email, if that is easy
- How many joints, rooms or windows are involved
Asking for a quote is easy: tell us what needs doing and where and its rough size. A few photos by email make the job easier to understand.
Common problems we fix in Widewall
Silicone only bonds to surfaces that are clean and dry. Soap film, dust, damp or old residue stop it gripping, so it starts lifting sooner than it should.
People usually contact us after spotting one of these:
- A second bead peeling off the first
- Smears and lumps from a botched reseal
- Decorators’ caulk around a bath or shower
- Floor or wall movement joints that have failed
In and around Widewall, as anywhere, good remedial sealant starts with a clean, dry, properly prepared joint.

Leave it or put it right?
Repeat failures have a cause. Taking time to find the cause, whether it’s movement, a leak or the wrong product, is what stops it happening again. 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 failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, send an email to info@mrmastic.co.uk and we will give you an honest view and a quote.

Your questions about remedial sealant in Widewall
Can you do remedial sealant in Widewall?
Yes. We work across all of Scotland, and Widewall is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.
Is there a guarantee on remedial sealant in Widewall?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Can failed expansion joints be resealed?
Yes. Backing sets the depth and stops the sealant sticking to the back.
Can you remove old sealant without damaging the bath?
Yes, with care. The old bead is cut and lifted with tools that suit the surface, and the residue is cleaned away. Any existing damage is pointed out before any work starts.
How long will it take to strip and reseal the joint?
The number of joints and layers decides it. You will have a timescale before any work begins.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
How the visit works
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours, depending on how many layers have to come out. For a place like Widewall, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Each layer is cut out and the residue cleaned off.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
How to prepare
- Clear the area around the work
- Mention any sign-in or site rules at work premises
- Tell us about any previous sealing or DIY attempts
