Commercial sealant for homes and businesses in Cottered
In showers and washrooms we use anti-fungal sanitary silicone, with a food-safe sealant by kitchen sinks where needed. We use sealants from Arbo and Everbuild, applied by ARBOMaster approved applicators. We work on student & care accommodation, retail & leisure sites and hotel bathrooms, and people most often call us about worktop sealant that has shrunk and stained and silicone laid over old silicone by a previous contractor.
Work in a small place like Cottered is planned ahead, journey included, so it can be fitted around guests, customers or events where possible.
All of our work is guaranteed for twelve months, in Cottered and everywhere else we cover.

The process
Before we leave, we go over the finished joints with you. The visit itself usually takes as long as the scope needs, from one welfare room to a full building, depending on the size of the job. In a small place like Cottered, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Tell us the rooms, hours and site rules, and we’ll plan the programme.
- We go through your site’s paperwork needs, such as RAMS, before work begins.
- Old sealant is cut out room by room and joints cleaned and treated.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealant elsewhere.
- Rooms are handed back in order, each with its cure time.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- For business premises, tell us about site rules or sign-in
- Where the joints are inside, avoid wetting them before we arrive

Advice
Why act early in Cottered
Fixing rooms one complaint at a time is the slow way. A planned programme deals with every room in order, keeping disruption down and costs clear. Around Cottered, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why us?
- Old sealant always removed completely
- Tidy, careful work
- Domestic, commercial and hotel work
- We’re fully insured

What affects the quote in Cottered
The price is agreed before any work begins. It’s based on:
- How much old sealant there is and how hard it is to remove
- The size of the job
- The product the joint needs
- Whether there’s mould to deal with
The cost reflects the work involved, not guesswork. That is why we ask about the job first and send you a clear quote before we start.
Asking for a quote
Before you ask for a quote, have a think about:
- How many joints, rooms or windows are involved
- The type of property
- Where the property is
- Access, such as stairs, a lift or height
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that’s easy.
What commercial sealant looks like in Cottered
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Community buildings like Parish Church of St John the Baptist are part of the picture too: halls and community kitchens see heavy use, and their sealant shows it. If you look after a building such as Freman College, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.

Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
