Commercial sealant for homes and businesses in Charlbury
Mr Mastic brings more than 20 years’ experience to commercial sites, and we are fully insured and ARBOMaster approved. Tell us what paperwork your site needs, such as RAMS or insurance details, and we’ll confirm what we can supply with the quote. If you have too many rooms to reseal without closing the building and sealant failing again soon after quick repairs, we can put it right, whatever the surface.
Around a place like Charlbury, halls, schools and small businesses all have washrooms and kitchens used by many people. Sealant and fire-rated joints there matter as much as in any larger building.
Whatever the size of the job, you get the same 12-month guarantee.

What happens on the day
There’s no need to move everything out, just the space around the work. We protect the rest, and the work takes a few hours for a single washroom, longer for a whole building in most cases. A visit to Charlbury is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We walk the site with you and agree the rooms, the order and the hours.
- Every area is sheeted and the old silicone stripped out.
- Joints are cleaned, treated for mould and dried.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealants elsewhere.
- We check every room and give its cure time for housekeeping.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention if the joints have been sealed before
- Mention any sign-in or site rules at work premises

Charlbury: your questions answered
Do you work for landlords with property near Charlbury station?
Yes. We work for landlords and letting agents as well as homeowners. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Is Charlbury within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is it OK to seal over old sealant?
No. The old sealant always comes out first, so the new sealant bonds properly.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
How long does the job take?
It depends on the size of the job, but as a guide it takes a few hours per area, with larger sites planned over several visits. We will give you a better idea when we quote.
Is out-of-hours working possible?
That can be arranged. The hours are agreed before work starts.
Can I choose the sealant colour?
Usually, yes. Sealants come in white, clear, grey and other colours for many products, and we will agree it with you first.
Workplaces and buildings in Charlbury
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
Schools such as Charlbury Primary School are buildings too, and sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours. Letting a property close to Charlbury station? Then we can quote for one property or a whole portfolio of rentals.

What affects the quote in Charlbury
Some jobs are bigger than they look, and some smaller. What affects the quote:
- How easy the joints are to reach
- How many areas need sealing
- How much old sealant there is and how hard it is to remove
- The size of the job
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Ask us for a quote and we will go through it with you.
What we need to know
When you contact us, these details help:
- The rough size of the job
- If someone has resealed it before
- The address or postcode of the job
- How we’d reach the joints
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. Whenever you’re ready, ring 0345 464 0079 or drop us an email.
Signs you need commercial sealant in Charlbury
Heavy use means more movement: different weights, constant use and daily cleaning all work at the joint. A tray that is not fully supported soon tears its seal.
People normally contact us after spotting something like this:
- Washroom sealant that looks dirty however often it’s cleaned
- Worktop sealant that has shrunk and stained
- Failed floor-level joints in accessible wet rooms
- Mouldy bathrooms flagged at a tenancy check
For buildings such as St Mary's Church, any kitchen and washrooms need the same sealant care as any other building.
Questions to ask before you book
- What preparation is included
- Are they insured?
- Is the old sealant removed completely?
- Whether you can choose the colour

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
If you’ve already had a go yourself, that is fine. We cut it out and start again.
Why deal with it now?
Sealant work is quick by the room: it takes a few hours per area, with larger sites planned over several visits. Each area is then left to cure for the time we give you, so the programme is planned around cure times. Homes in smaller places like Charlbury can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and agree the price before starting.
Why us?
- Fully insured
- Experience in homes, commercial sites and hotels
- A choice of colours where the product allows
- Neat joints and a tidy finish
