Washroom sealing for commercial buildings in Coates
Black spotting along a sealant bead is not a cleaning problem. The growth is inside the sealant, which is why it comes back however often it is treated. Replacing the bead is the lasting treatment. If you have a new bead over an old one coming away and panel joints letting water behind, we can help, on accessible toilets and changing rooms, vanity units and basins and showers, trays and wet room floors alike. Searching for sealant specialists in Coates? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Community buildings around smaller places like Coates have kitchens and toilets used by many people. Resealing sinks, worktops and WCs with anti-mould silicone keeps them clean and watertight.
A 12-month guarantee applies to all our work in West Sussex. Should something we installed fail, ring 01277 525 020 or send photos by email and we’ll come back to it.

Why act early in Coates
Running fresh silicone along a failed bead hides the problem briefly. Silicone won’t grip silicone, so it lifts and holds moisture underneath. Cutting out completely and cleaning back takes a little longer and lasts. Converted and older buildings near places like Coates tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
Why appoint us
- Colour agreed before work starts
- RAL and finish matching where the product range allows
- Constructionline member for supplier checks
- Fixed quotes based on photos, drawings or a visit
Take a look at what affects the cost and our accreditations and insurance.
General trades versus a specialist
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
What we can’t put right
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Fittings that move too much to hold a bead
- Panel boards already damaged by water
- Condensation from failed extract fans
If in doubt, call the office on 01277 525 020 or send photos by email and we’ll say what we think before you book.

What sets the cost
The price varies from site to site. It mainly depends on:
- Induction, permit and paperwork requirements
- The product specified
- Location, for remote and island sites
- Phasing around occupants
Pricing washrooms and wet areas depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.
Sending details for a quote
A good diagnosis starts with the right details. Tell us:
- Whether an asbestos survey exists
- Rough lengths or quantities, or drawings if you have them
- Any dates the work must fit around
- Specification clauses that apply
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to give us a call on 01277 525 020 or email the details over with what you know.
When to call us in Coates
Occasionally a joint keeps failing because of a problem behind it: a loose panel, a leaking waste or water coming through the wall. We check for that first and tell you if another trade is needed.
Site and facilities staff are often the first to spot these:
- Black mould inside silicone joints that cleaning can’t shift
- Discoloured joints around urinals and WC pans
- Sealant lifting along a tray edge
- Kitchen worktop joints that can’t be kept clean
Halls linked to places like Church of St Agatha host groups all week, which is hard on kitchen and toilet sealant.

Your questions answered
What paperwork can you provide for a job in Coates?
We will confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We are CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.
Is Coates too small for you to travel to?
Not at all. Coates is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
What sealant do you use in washrooms?
An anti-mould sanitary silicone for most washroom joints. Neutral-cure grades are used where acetoxy types could mark metals, stone or mirror backings.
How long does a typical visit take?
We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.
When can showers be used after new sealant?
That varies with the sealant and the room temperature. Each room gets its own reopening time from us before we leave it.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Our process
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. Smaller jobs around Coates can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
- The phasing is agreed so there are always facilities open.
- We strip out the old bead and clean off the residue left behind.
- Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
- We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
- Each room is handed back once the sealant has had its cure time.
Getting the site ready
- Send any specification or drawings in advance
- Agree which areas must stay open
- Share the asbestos register for older buildings
