Remedial sealant in Steinis, done properly
Not every leak is a sealant leak. A cracked tray, a failed shower valve or a leaking waste can look just the same. If that is what we find, we will tell you rather than reseal something that will not fix it. We work on expansion joints, botched or over-sealed joints and leaking tray & enclosure joints, and the jobs we see most are gaps opening along the back of the worktop and products that weren’t meant for the joint.
In and around a place like Steinis, homes range from older stone-built properties to newer houses. Older buildings can move a little, and that shows first in cracked grout and split sealant.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Remedial sealant around Steinis
Steinis 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, and sealant and grout that work that hard wear out sooner. Scottish Water supplies are generally soft, so limescale is less of a problem than in hard-water areas. But mould still grows into sealant and grout in a room that does not dry out.
Whether the job is in Steinis itself or nearby, the right material for each joint matters as much as a neat finish. Around Steinis, as everywhere, remedial sealant is only as good as the preparation behind it.
Steinis is in Na h-Eileanan Siar. Jobs in Steinis get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. Steinis is one of 87 places in Na h-Eileanan Siar where we work.

How the visit works
There is not much for you to do on the day. Show us the job and we will take it from there. The job generally takes a few hours for a typical bath or shower, longer where several layers have been applied. Outside jobs in Steinis need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- 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.
Getting ready for the visit
- Let us know about parking restrictions
- Keep pets and children clear of the area while we work
- Where the joints are inside, avoid wetting them before we arrive

How we quote for remedial sealant
Some jobs are bigger than they look, and some smaller. The main factors:
- Any working-time requirements on site
- Which sealant suits the joint
- The number and length of the joints
- Mould in or behind the old joints
What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- How many joints, rooms or windows are involved
- Any previous sealing or DIY work
- Whether it’s a home or a business
- Any access issues, like height or stairs
To get a quote, send an email to info@mrmastic.co.uk and tell us where the job is and what the problem looks like. We will send you a clear quote before any work starts.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
What we cannot put right
We’d rather tell you now than do work that won’t last, so these are the limits:
- Movement from fittings that are not supported
- Tiles that have come away from the wall
- Sealant in an older building that needs testing for asbestos first
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think before you book.
What we seal
- Mouldy bath & shower sealant
- Leaking tray & enclosure joints
- Expansion joints
- Shrunken worktop sealant
- Botched or over-sealed joints
- Failed movement joints
Leave it or put it right?
Leaks that are left keep doing damage out of sight: wet floors, stained ceilings and swollen worktops. Dealing with the joint now is a small job by comparison. In a place like Steinis, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and send you a clear quote before work begins.

Surface by surface
Over-sealed & botched joints
A thick bead smeared across tiles often hides mould or gaps. Taking it back shows what’s underneath, then reseal neatly.
Mouldy bath & shower sealant
Repeat mould generally points to a damp, poorly aired room. Along with resealing, we will mention if the room needs better ventilation.
Common questions in Steinis
Do you take on hotel work around Steinis?
Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.
Will you come out to Steinis?
Yes, smaller places are covered as well as towns. We work across all of Scotland, including the islands, where work is planned around ferry crossings. Just mention lanes, gates or anything else about the route when you book.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all.
Can you take off two layers of silicone?
Yes. Both layers come out; over-sealing fails because silicone won’t bond to silicone.
What happens if the problem is the tray or the plumbing?
We check for that before we reseal. If the fault is elsewhere, you’ll know before any work is done.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
