For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can go on one quote.
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
What the job involves on each surface
Hotel bathrooms
Hotel showers and baths get used and cleaned every day, so joints are finished smooth and sealed with anti-fungal sanitary silicone.
Retail & leisure sites
Customer toilets reflect on the business, and clean, neat sealant makes them look cared for.
What we’re called out for in Blackwood
Commercial bathrooms get far more use than domestic ones, and they’re cleaned with strong products every day. So the silicone ages faster than it would at home.
People generally contact us after spotting one of these:
- Too many rooms to reseal without closing the building
- Mouldy washroom sealant that staff and guests notice
- Failed floor-level joints in accessible wet rooms
- Split sealant around staff kitchen worktops and sinks
In and around Blackwood, as anywhere, good commercial sealant starts with a clean, dry, properly prepared joint.
Questions to ask before you book
- The length of the guarantee
- How the colour is chosen
- How hidden problems are handled
- Whether the sealant suits the joint

Why act early in Blackwood
Before an inspection, audit or busy season, sealant is easy to overlook. Booking it in good time leaves room for the cure time before the visit. In a place like Blackwood, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Doing several joints on one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll give you a clear quote for the lot.
What you get with us
- A sealant colour to suit the surroundings
- Anti-fungal silicone where joints get wet
- Experience in homes, commercial sites and hotels
- Trusted Arbo and Everbuild sealants

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Keep a record of which rooms were resealed and when
- Book larger programmes for quieter times of year
- Ask cleaners to go gently on the silicone
- Pass on the cure time to whoever cleans the rooms
Squeegees in guest and staff showers help: walls and trays dry faster, and so does the sealant.
Water from a failed shower seal can travel: through floors, into ceilings and across into corridors. Dealing with the joint early stops that spread.
How it works
We bring everything the job needs with us, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes anything from a few hours to several days, depending on the number of rooms. For a place like Blackwood, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- Tell us the rooms, hours and site rules, and we will plan the programme.
- Tell us what paperwork your site needs, and we confirm what we can supply before work begins.
- In each room, the old bead comes out and the joint is cleaned and treated.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealant elsewhere.
- Rooms are handed back in order, each with its cure time.
How to prepare
- Clear items away from the joints we’re working on
- Tell us about any water getting in
- Mention any parking rules near the property

Will you come out to Blackwood?
Yes. Blackwood is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Will there be a smell?
Possibly a little. It fades as the sealant cures.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
How soon can a room be used after resealing?
Around 24 hours is typical for sanitary silicone. Housekeeping get the cure time for each room.
Do you offer different sealant colours?
Generally, yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before work begins.
Do you take on large, multi-room jobs?
Yes. Our team has more than 20 years’ experience, and large programmes are planned around how the building is used.
What does commercial sealant cost?

When something else is needed
Sealant is not the answer to every problem, and we’ll tell you before work begins. Sealant won’t put right:
- Fire risk assessments or certification
- Leaking pipework, valves or wastes (a plumber’s job)
- Failed tanking or loose tiles behind the sealant
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly.
