Do you need commercial sealant in Wherwell?
In office kitchens and tea points, joints are wet and wiped all day, and grease and cleaning sprays break down sealant. Worktop and sink joints are often the first to go.
These are the problems we’re asked about most:
- Split sealant around staff kitchen worktops and sinks
- Tired sealant ahead of a health and safety audit
- Washroom sealant that looks dirty however often it’s cleaned
- Rental bathrooms that need resealing between tenants
Schools such as Wherwell Primary School are buildings too, and busy washrooms and kitchens can be resealed in phases so they stay open.

- What happens if they find a problem under the old sealant
- Whether they’re fully insured

What the job involves on each surface

Landlords and agents can have several properties resealed in one programme, with each one done when access suits.
Student & care accommodation
Vacant rooms make resealing quick and simple.
Workplaces and buildings in Wherwell
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
Letting a property close to Andover station? Then several rental properties can be resealed on one programme. For buildings such as Church of St Peter and Holy Cross, halls and community kitchens see heavy use, and their sealant shows it.

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
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 be quoted together.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
The process
At the end, we look at the finished work together and tell you how long to leave it. The visit itself generally takes a few hours per area, with larger sites planned over several visits, depending on the size of the job. For a village or hamlet like Wherwell, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we visit and agree the scope, the sequence and the working 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.
- Rooms are checked and returned with a cure time so staff know when to use them.
How to prepare
- Mention any leaks or damp you’ve noticed
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any previous sealing or DIY attempts

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Keep a record of which rooms were resealed and when
- Report broken fans quickly
- Include the silicone on your room checklists
- Keep strong chemicals and scourers off the joints
Make it easy for staff to flag a failing joint. Catching one split early can save a leak later, and if anything looks wrong, just ring 0345 464 0079 or drop us an email.
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.
FAQs for Wherwell
I let a flat near Andover station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will send you a clear quote.
Is Wherwell in your area for commercial sealant?
Yes. We work across London and the South East, and Wherwell is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing, and we will give you a clear quote.
Can you take on a whole building?
Yes. We’ll walk the site, agree the scope and the order, and you get one clear quote.
How long does the job take?
That depends on the amount of work, but as a guide it takes a few hours per room, so whole buildings are phased. We’ll give you a better idea when we quote.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Wherwell and the rest of Hampshire.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and we will quote it together.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in.
Leave it or put it right?
Replacing a whole washroom takes time, money and several trades. If the fittings are in good order, new sealant is often all it needs. We’ll tell you if we find anything that needs another trade. Older cottages and farmhouses around Wherwell can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.
Why us?
- A choice of colours where the product allows
- 180+ five-star Google reviews
