Commercial sealant for homes and businesses in South Dell
Student halls, care homes and supported housing have many similar bathrooms. We agree a programme and work through them in order, fitting around residents and staff. We work on rental portfolios, office washrooms & kitchens and welfare facilities, and the jobs we see most are worktop sealant that has shrunk and stained and black, stained silicone in guest bathrooms.
Commercial work around smaller Scottish places tends to mean hotels, guest houses, schools and halls rather than offices. Each needs sound sealant in its washrooms and kitchens, and fire-rated joints kept in good order.
Each job carries a 12-month guarantee.

Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
What commercial sealant looks like in South Dell
If you run a hotel, guest house or holiday let in a coastal place like South Dell, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. In Scotland, private landlords have to meet the Repairing Standard, and keeping sealant sound across a portfolio is part of that.
For jobs in and around South Dell, choosing the right material for each joint is as important as a tidy finish. Around South Dell, as everywhere, commercial sealant is only as good as the preparation behind it.

Common questions in South Dell
What guarantee comes with commercial sealant in South Dell?
All our work, in South Dell and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Do you cover smaller places like South Dell?
Yes, we do. Our work covers the whole of Scotland, islands included, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
Where is Mr Mastic based?
We work from Crawley. We cover South Dell and the rest of Na h-Eileanan Siar.
Can you reseal every bathroom in a hotel?
Yes, we can. Larger jobs are planned as a room-by-room or floor-by-floor programme, keeping most of it in use.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Do you remove the old sealant?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll tell you what we are using.
What the job involves on each surface
Retail & leisure sites
Changing areas and showers at leisure sites are wet all day, so anti-fungal sanitary silicone is the product we use.
Welfare facilities
Failed sealant in welfare areas is a simple fix before an audit. Let us know when it needs to be done and we will schedule around it, cure time included.
Leave it or put it right?
Fixing rooms one complaint at a time is the slow way. A planned programme deals with every room in order, with less disruption and one clear quote. In an older home around South Dell, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
The cost reflects the work involved, not guesswork. That is why we ask about the job first and send you a clear quote before any work starts.

How the visit works
When we arrive, we look over the joints with you first. We protect the surfaces around the joints before any work begins. The work normally takes as long as the scope needs, from one welfare room to a full building. 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.
- We clean the joints, treat any mould and let them dry.
- We lay the right sealant for each area, with anti-fungal silicone in wet rooms.
- We check every room and give its cure time for housekeeping.
Preparing for the visit
- Mention any parking rules near the property
- Mention if the joints have been sealed before
- For indoor joints, keep the area dry beforehand if you can

Can I do it myself?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Ask cleaners to go gently on the silicone
- Report broken fans quickly
- Leave squeegees in busy showers
- Act on lifting sealant before it leaks
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.
Black sealant in a staff washroom or guest bathroom draws complaints. The longer it’s left, the deeper it grows into the silicone, so the fix is replacement.
