King's Somborne: your questions answered
Do you work for landlords with property near Mottisfont & Dunbridge station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
Can you do commercial sealant in King's Somborne?
Yes. Our work covers London and the South East, and King's Somborne is part of that. You can call 0345 464 0079 or send us an email and let us know what needs doing.
Can you work outside opening hours?
That can be arranged for many jobs. We’ll confirm the working hours with your quote.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
How long does commercial sealant take?
It depends on the size of the job, but most jobs take a few hours per area, with larger sites planned over several visits. We’ll tell you when we quote.
Do you take on large, multi-room jobs?
Yes. We will walk the site, agree the scope and the order, and you get one clear quote.
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.
Do you guarantee commercial jobs?
Yes. Every job, domestic or commercial, carries our one-year guarantee.
Looking after it afterwards
So the new joints stay in good condition:
- Keep extractor fans working and serviced
- Tell cleaning staff when each room can be used
- Get split or lifting joints looked at early
- Use mild cleaners on sealant, not bleach or abrasives
Ask staff to report splits or lifting sealant early. Catching one split early can save a leak later.
A room that cannot be let or used is lost income. Small sealant faults caught early can be fixed between bookings or tenancies, before they become leaks that take the room out of use.
The process
When we arrive, we look over the joints with you first, so you know exactly what we’re doing. We protect the surfaces around the joints before any work begins. The work generally takes a morning for a small washroom, and a planned programme for bigger sites. Somewhere like King's Somborne needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
- We reseal with the right product for each joint.
- Each finished area is checked with you and given a cure time.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Let us know about stairs, lifts or work at height
- Move anything stored near the joints
How to get a quote

- Black, stained silicone in guest bathrooms
- Silicone laid over old silicone by a previous contractor

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Commercial sealant in King's Somborne: local notes
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
For buildings such as Church of St Peter and St Paul, halls and community kitchens see heavy use, and their sealant shows it. If you look after a building such as King's Somborne Church of England Primary School, washroom and kitchen sealant can be programmed around term times or opening hours.

Leave it or put it right?
Guests and staff judge a building by its bathrooms. Black sealant makes a clean room look dirty, and cleaning rarely puts it right. New sealant does. Where a wall is exposed, as many are in small places like King's Somborne, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
