Commercial sealant in Selsdon
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 provide. We are often asked to deal with worktop sealant that has shrunk and stained and silicone laid over old silicone by a previous contractor, across student & care accommodation, retail & leisure sites and rental portfolios.
Community buildings, schools and small businesses around places like Selsdon have washrooms and kitchens that see a lot of use. Sealant and fire-rated joints there matter as much as in any larger building.
The work is covered for a year after we finish. If anything isn’t right with it, phone 0345 464 0079 or email us.

Leave it or put it right?
Sealant is easy to forget until an audit or inspection is due. Booking it in good time leaves room for the cure time before the visit, without a last-minute rush. Homes in smaller places like Selsdon 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.
Doing several joints on one visit usually makes better use of the time than several visits. We’ll give you a clear quote for the lot.
Why us?
- Trusted Arbo and Everbuild sealants

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
For landlords and businesses
We also work for property managers and facilities teams. Several sites can go on one quote, and we’re fully insured for the work.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

What else we do in Selsdon
Signs you need commercial sealant in Selsdon
Shower trays and baths in busy buildings move more: people of all sizes, daily cleaning and constant loading. If a tray flexes, the sealant around it splits.
It’s worth asking for a quote if you see:
- Too many rooms to reseal without closing the building
- Silicone laid over old silicone by a previous contractor
- Washrooms that need sorting before an inspection
- Washroom sealant that looks dirty however often it’s cleaned
If you look after a church, hall or community building such as St Francis, its kitchen and washroom sealant needs looking after like anywhere else.
Questions to ask before booking
- How the colour is chosen
- Which sealant they’ll use, and why
- The length of the guarantee
- How much experience the applicator has
How the job changes by surface
Rental portfolios
Between tenancies is a good time to reseal, so the next tenant moves in to clean, sound joints.
Student & care accommodation
Halls and care homes often have many near-identical bathrooms. A room-by-room programme keeps the job efficient.
What affects the quote in Selsdon
There’s no set price list, because no two jobs are the same. What we look at:
- How much old sealant there is and how hard it is to remove
- The size of the job
- Access and height
- How many areas need sealing
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

Commercial sealant around Selsdon

FAQs for Selsdon
Do you work for landlords with property near Sanderstead station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Do you cover smaller places like Selsdon?
Yes. Selsdon is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Where do you work from?
We are based in Crawley, and we cover South East England, London and all of Scotland.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Do you provide RAMS?
We’re fully insured, and we’ll go through your site’s requirements with you. We will confirm what we can supply when we quote.
Do you take out the old sealant first?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
How soon can a room be used after resealing?
Most areas can be used after around 24 hours. Each room is handed back with the cure time for the product used.
