For landlords and businesses
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can go on one quote.
Common problems we fix in Sandwick
A rushed reseal between guests rarely lasts. New silicone over old, joints that weren’t dried, or an unsuitable product means the joint fails again soon.
Common reasons people contact us are:
- Mouldy washroom sealant that staff and guests notice
- Water marks on ceilings under bathrooms
- Mouldy bathrooms flagged at a tenancy check
- Repeated reseals that do not last
Whether the job is in Sandwick itself or nearby, the right material for each joint matters as much as a neat finish.
Before booking anyone
- Are they insured?
- Whether you can choose the colour
- Whether all the old sealant comes out first
- What product goes in the joint
Aftercare tips
Good habits help new joints last longer. Our tips:
- Log resealing so you know what’s due
- Don’t leave a failed joint until the next refurbishment
- Put a squeegee in each shower
- Ask cleaners to go gently on the silicone
Daily cleaning with harsh chemicals shortens the life of any sealant. Ask cleaners to use mild products and soft cloths on the sealant, with stronger products kept off the bead.
Water from a failed shower seal can travel: into ceilings below, walls next door and service voids. Early resealing keeps it from getting that far.
How the visit works
On the day, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before work begins. Most jobs take a few hours per room, so whole buildings are phased. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- We walk the site with you and agree the rooms, the order and the hours.
- Room by room, we protect the area and remove all the old sealant.
- Joints are cleaned, treated for mould and dried.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealants elsewhere.
- Each room is checked and handed back with its cure time.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Keep children and pets away from the work area
- Let us know if you’ve seen damp or leaks

Sandwick questions
Will you come out to Sandwick?
Yes, Sandwick is covered. Our work covers the whole of Scotland, islands included, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you do commercial sealant in Sandwick?
Yes, Sandwick is within the area we cover. We work across all of Scotland. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing, and we’ll send you a clear quote.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
What information do you need?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Can you seal over the old sealant?
No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
What does commercial sealant cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before work begins.
Do you remove the old sealant?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

In Scotland, private landlords have to meet the Repairing Standard, and keeping sealant sound across a portfolio is part of that.
In and around Sandwick, as anywhere, good commercial sealant starts with a clean, dry, properly prepared joint.
