About our commercial sealant in Coscote
Mr Mastic brings more than 20 years’ experience to commercial sites, and we’re fully insured and ARBOMaster approved. Tell us what paperwork your site needs, such as RAMS or insurance details, and we will confirm what we can supply with the quote. Typical jobs include tired sealant in let properties and tired sealant ahead of a health and safety audit, on hotel bathrooms, rental portfolios and retail & leisure sites.
Somewhere as small as Coscote, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
Big or small, it’s backed by our 12-month guarantee.

Commercial sealant in Coscote: local notes
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Rented homes near Didcot Parkway station change hands often, and several rental properties can be resealed on one programme. Schools such as Hagbourne Church of England Primary School are buildings too, and busy washrooms and kitchens can be resealed in phases so they stay open.
Coscote is about 1 mile south of Didcot, in Oxfordshire. Every kind of property in Coscote is covered for commercial sealant, old or new, large or small. The work is guaranteed for a year. 443 places in Oxfordshire are on our list, from the larger towns to small villages. You can also see our page for Oxford, roughly 11 miles from Coscote.

Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What we’re called out for in Coscote
Larger buildings move, and lightweight partitions flex more than masonry. Joints between different materials take the strain.
Look out for any of the following:
- Mouldy washroom sealant that staff and guests notice
- Mouldy bathrooms flagged at a tenancy check
- Failed floor-level joints in accessible wet rooms
- Repeated reseals that do not last
If you look after a church, hall or community building such as Church of St Andrew, any kitchen and washrooms need the same sealant care as any other building.

What happens on the day
On the day, we start by going over the job with you. We protect the surfaces around the joints before any work begins. Most jobs take a few hours for a single washroom, longer for a whole building. Somewhere like Coscote needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We walk the site with you and agree the rooms, the order and the hours.
- Room by room, we protect the area and remove all the old sealant.
- 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.
Getting ready for the visit
- Move anything stored near the joints
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property

Do you provide RAMS?
Let us know which documents your site needs, for example RAMS or insurance details, and we’ll confirm what we can provide when we quote.
Can you match the sealant colour?
We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Is there any odour?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first.
Can you take on a whole building?
Yes, we can. Larger jobs are planned as a room-by-room or floor-by-floor programme, keeping most of it in use.
What affects the cost of commercial sealant
Some jobs are bigger than they look, and some smaller. The main factors:
- Mould in or behind the old joints
- The old material and how stubborn it is
- When we can work, for business premises
- How easy the joints are to reach
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or email us.
What to tell us for a quote
When you call or email, these details help:
- The type of property
- What the problem is, such as mould, gaps, leaks or cracking
- Access, such as stairs, a lift or height
- The rough size of the job
Asking for a quote is easy: let us know what needs doing and where and its rough size. A few pictures by email make the job easier to understand.

Retail & leisure sites
