Why act early in Great Thorness
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, without a last-minute rush. In a small place like Great Thorness, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Why choose Mr Mastic in Great Thorness
- Any old sealant cut out fully, not covered over

What commercial sealant looks like in Great Thorness
For seaside hotels, guest houses and holiday lets around Great Thorness, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Whether the job is in Great Thorness itself or nearby, the right material for each joint matters as much as a neat finish.

Great Thorness questions
Do you cover smaller places like Great Thorness?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
What guarantee comes with commercial sealant in Great Thorness?
All our work, in Great Thorness and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Which products 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.
What do you need from me for a quote?
The location, the problem and the rough size of the job. If you can, email a few photos.
How long does the job take?
It depends on the size of the job, but as a guide it takes a few hours per room, so whole buildings are phased. We’ll tell you when we quote.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Great Thorness, along with the rest of our area.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures.
Signs you need commercial sealant in Great Thorness
Commercial buildings settle and move with temperature, and stud walls move more than solid ones. The sealant between walls, trays and fittings absorbs that strain.
The problems people generally mention when they call are:
- Mouldy washroom sealant that staff and guests notice
- Failed floor-level joints in accessible wet rooms
- Sealant failing again soon after quick repairs
- Large numbers of bathrooms needing the same work
Around Great Thorness, as everywhere, commercial sealant is only as good as the preparation behind it.
Questions to ask before you book
- Is the old sealant removed completely?
- What insurance they hold
- How the surfaces are prepared before sealing
- How the colour is chosen
Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
How it works
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the job takes a few hours per room, so whole buildings are phased for a typical job. Somewhere like Great Thorness needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
