About our commercial sealant in Offham
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. Common call-outs are for large numbers of bathrooms needing the same work and sealant failing again soon after quick repairs, across rental portfolios, hotel bathrooms and welfare facilities.
In a village or hamlet like Offham, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
A one-year guarantee comes as standard.

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Don’t leave a failed joint until the next refurbishment
- Schedule work around occupancy
- Put a squeegee in each shower
- Use mild cleaners on sealant, not bleach or abrasives
Keep the extraction running and maintained. In internal bathrooms, a weak or broken fan lets moisture linger, and that’s what keeps mould away.
Mould in shared washrooms gets noticed and talked about. Left long enough, it spreads through the bead, and only replacement fixes it.

Workplaces and buildings in Offham
There are hotels and other places to stay in and around Offham. Hotel work can be planned room by room, with out-of-hours working where needed. Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.
Community buildings like Church of St Peter are part of the picture too: halls and community kitchens see heavy use, and their sealant shows it. If you look after a building such as Wallands Community Primary School, washroom and kitchen sealant can be programmed around term times or opening hours.

What we’re called out for in Offham
In an accessible wet room, water spreads across the floor every use, so floor-to-wall joints take standing water. A failed joint there can soon let water into the floor or walls.
Keep an eye out for any of the following:
- Tired sealant ahead of a health and safety audit
- Large numbers of bathrooms needing the same work
- Tired sealant in let properties
- Split sealant around staff kitchen worktops and sinks
Letting a property close to Cooksbridge station? Then several rental properties can be resealed on one programme.

What sealant work cannot fix
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- Failed tanking or loose tiles behind the sealant
- A shower tray, bath or basin that’s cracked or broken
- Leaking pipework, valves or wastes (a plumber’s job)
If in doubt, phone 0345 464 0079 or email us and we will say what we think.
What we seal
- Welfare facilities
- Rental portfolios
- Student & care accommodation
- Retail & leisure sites
- Hotel bathrooms
- Office washrooms & kitchens
What affects the cost of commercial sealant
The quote reflects the job in front of us. We take into account:
- Any working-time requirements on site
- Whether old sealant or filler has to be cut out
- Whether the work is at height
- The type of sealant required
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.
What we need to know
Photos help, but a description is a good start. Please mention:
- Any previous sealing or DIY work
- Roughly how big the job is
- Where the property is
- A few pictures by email, if you can
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email pictures if that’s easy.
What we do, step by step
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes anything from a few hours to several days, depending on the number of rooms. In a small place like Offham, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We walk the site with you and agree the rooms, the order and the hours.
- Each area is protected and the old sealant cut out completely.
- The joints are degreased, treated and left to dry.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealants elsewhere.
- Each room is checked and handed back with its cure time.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- For business premises, tell us about site rules or sign-in
- Let us know about earlier repairs to the joints

Questions from Offham
Do you take on hotel work around Offham?
Yes, we work for hotels as well as homes and businesses. Rooms can be done a few at a time, so the building stays open.
Do you cover smaller places like Offham?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
Do I need to be at home?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Can you supply method statements and risk assessments?
Let us know which documents your site needs, such as method statements, risk assessments or insurance details, and we’ll confirm what we can provide when we quote.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before resealing.
How long do rooms need to be out of use?
Normally after around 24 hours. Each room is handed back with the cure time for the product used.
Different surfaces, different methods
Welfare facilities
Failed sealant in welfare areas is a simple fix before an audit. Tell us your deadline and we will schedule around it, cure time included.
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.
Why it’s worth doing now in Offham
Replacing a whole washroom takes time, money and several trades. If the fittings are in good order, new sealant is often all it needs. If something else is wrong, we’ll say so. Where a wall is exposed, as many are in small places like Offham, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and agree the price before starting.
