Commercial sealant in Mark Cross
Mr Mastic brings more than 20 years’ experience to commercial sites, and we’re fully insured and ARBOMaster approved. If your site needs RAMS or insurance details, tell us, and we will confirm what we can provide. We work on retail & leisure sites, rental portfolios and welfare facilities, and the jobs we see most are tired sealant ahead of a health and safety audit and sealant failing again soon after quick repairs.
If you have holiday lets, a converted barn used for business or a community building near Mark Cross, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
All our work is covered by a one-year guarantee.

What commercial sealant looks like in Mark Cross
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
For site and facilities teams at buildings such as Mark Cross Church of England Aided Primary School, washroom and kitchen sealant can be programmed around term times or opening hours. If you let a flat or house near Wadhurst station, sealant work can be quoted for a single flat or a whole portfolio.

Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.
Will you come out to Mark Cross?

Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.

What the job involves on each surface
Office washrooms & kitchens
A row of basins on a vanity top has a long joint that collects water. It’s cut out, cleaned and resealed in one neat line.
Hotel bathrooms
We work through hotel rooms in agreed batches, keeping most of the hotel open. Each room is handed back with its cure time for housekeeping.
What happens if it’s left?
Sealant is easy to forget until an audit or inspection is due. Planning the work ahead means rooms are finished and cured in time. Around Mark Cross, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
What you get with us
- We never seal over old sealant
- Arbo and Everbuild products
- White, clear, grey or coloured to suit, where the product allows
- Experience in homes, commercial sites and hotels

DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
What happens on the day
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. It normally takes a few hours per area, with larger sites planned over several visits. In a small place like Mark Cross, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- The first visit is a look round the site to agree the scope.
- Working hours are agreed, including early starts or out-of-hours work where it can be arranged.
- Areas are protected and the failed sealant removed.
- Joints are dried, then resealed and tooled neatly.
- Housekeeping or site staff are told when each area can be used.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Try not to wet indoor joints just before the visit
- Mention if the joints have been sealed before
Getting a quote
We quote each job on its own, so the first step is telling us about yours. Simply phone 0345 464 0079 or drop us an email and describe the job and send photos if you have them.

What we’re called out for in Mark Cross
In office kitchens and tea points, joints are wet and wiped all day, and grease and cleaning sprays break down sealant. The worktop and sink edges usually fail first.
Most people get in touch when they notice one of these:
- Sealant failing again soon after quick repairs
- Whole floors of tired en suites
- Mouldy bathrooms flagged at a tenancy check
- Washroom sealant that looks dirty however often it’s cleaned
If you look after a church, hall or community building such as St Marks, its kitchen and washroom sealant needs looking after like anywhere else.
Questions to ask before you book
- How much experience the applicator has
- How hidden problems are handled
- What the quote includes, VAT included or not
- How long to leave it before use
