Different surfaces, different methods
Hotel bathrooms
We can plan around check-out and check-in times.
Retail & leisure sites
Gym and leisure changing rooms take heavy use and plenty of water, so anti-fungal sanitary silicone is the product we use.
What we cannot put right
Before you book, it’s worth knowing the limits:
- Assessing what fire stopping a building needs
- Extraction that isn’t working, which needs an electrician or ventilation contractor
- Failed tanking or loose tiles behind the sealant
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think before you book.

Common questions in Rableyheath
Is Rableyheath in your area for commercial sealant?
Yes. Our work covers London and the South East, and Rableyheath is part of that. Just phone 0345 464 0079 or email us with a few details of the job.
Do you cover smaller places like Rableyheath?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
How long does commercial sealant take?
Most jobs take a few hours per area, with larger sites planned over several visits, including the preparation. We will confirm how long when we quote.
Can you reseal bathrooms across several rental properties?
Yes. We reseal bathrooms and kitchens in rented homes, and we can quote for several addresses at once.
Where is Mr Mastic based?
We work from Crawley. We cover Rableyheath and the rest of Hertfordshire.
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.
Can you reseal hotel rooms while we stay open?
Generally, yes. We agree the room order and times with your managers, and each room is handed back with a cure time.
Leave it or put it right?
Fixing rooms one complaint at a time is the slow way. A planned programme works through every room, keeping disruption down and costs clear. Around Rableyheath, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

What we do, step by step
We keep the work tidy and contained to the joints we’re treating. The job generally takes a morning for a small washroom, and a planned programme for bigger sites, and we tell you how long to leave it before we go. Somewhere as small as Rableyheath, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We agree a programme with you: which rooms, in what order, at what times.
- We go through your site’s paperwork needs, such as RAMS, 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.
Before we arrive
- Mention any sign-in or site rules at work premises
- For indoor joints, keep the area dry beforehand if you can
- Let us know about stairs, lifts or work at height

Signs you need commercial sealant in Rableyheath
Larger buildings move, and lightweight partitions flex more than masonry. Joints between different materials take the strain until it tears.
The most common problems we see are:
- Whole floors of tired en suites
- Leaks from showers into rooms or ceilings below
- Black, stained silicone in guest bathrooms
- Sealant failing again soon after quick repairs
For buildings such as Church of St Michael and All Angels, its kitchen and washroom sealant needs looking after like anywhere else.
Questions to ask before booking
- Whether they seal over old material or remove it
- How long to leave it before use
- How much experience the applicator has
- Whether they’re fully insured
How to look after the new joints
Good habits help new joints last longer. Our tips:
- Include the silicone on your room checklists
- Keep extractor fans working and serviced
- Pass on the cure time to whoever cleans the rooms
- Book larger programmes for quieter times of year
Each room is handed back with its cure time, usually around 24 hours. Make sure housekeeping or cleaning staff know it so the new sealant is not wetted or scrubbed too soon.
Watch for the warning signs: black spots in the silicone, corners lifting, staining on the ceiling below or a musty smell. When you see them, it’s time to plan a reseal.

Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
