About our washroom sealing in Shoreham
In a busy washroom, the sealant typically gives up long before the tiles or fittings. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning, and once mould grows into it, it can’t be scrubbed out. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. Most enquiries involve kitchen worktop joints that can’t be kept clean and mould spotting along silicone joints, across showers, trays and wet room floors, kitchens and tea points and vanity units and basins. Searching for sealant specialists in Shoreham? Mastic Doctor has worked for contractors, FMs and building owners since 2005.

Should maintenance staff do it?
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.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
What we can’t put right
Some faults sit outside our scope, and we say so rather than covering them up:
- Leaks through tanking or membranes below the finishes
- Vanity carcasses that have swollen
- Condensation from failed extract fans
If you are not sure, just ring 01277 525 020 or email the details over and we’ll give you a straight answer.

Signs you need washroom sealing in Shoreham
Panels and vanity units move slightly in use and trays shift slightly with each user. A bead that can’t cope with the movement splits along one edge.
Clients typically get in touch after noticing something like this:
- Shower tray joints that have opened up
- Stained sealant around pans and urinals
- Failed sealant in a tea point or staff kitchen
- Panel joints letting water behind
Healthcare estates like Chelsfield Park Hospital (2.6 miles north-west of Shoreham) expect contractors to follow their permits and cleaning rules in every washroom.

What the job involves on each surface
Showers and trays
Shower joints in hotels, gyms and workplaces work hard. Each bead is stripped, the joint dried and new sealant laid.
Basins and vanity tops
A failed joint along a vanity unit lets water into the carcass. Prompt resealing keeps the unit sound.
On site: what to expect
Working in a building that stays open takes some planning. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. If others near Shoreham need work, visits can be combined. You will have a fixed quote before work starts.
- We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
- A phasing plan keeps part of the building’s facilities in use at all times.
- Failed silicone is removed completely and the surfaces cleaned of every trace.
- We clean and dry every surface so the new sealant can grip.
- We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
- You get a reopening time for every room, with signage left up until then.
Before we start on site
- Confirm the product named in the specification
- Let us know about inductions and permits
- Tell staff and tenants when we will be in

Related advice
Why it’s worth doing now in Shoreham
Gaps and mould in joints give dirt and bacteria somewhere to sit which matters most in healthcare, food and education settings. A smooth, sealed joint can be cleaned properly. Older rural buildings around Shoreham move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Your questions answered
Will all the washrooms in our Shoreham building be closed at once?
Rarely all at once: work is phased so some facilities are always available. Each area is handed back once the sealant has cured enough to use.
Is Shoreham off your patch?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.
Can washrooms stay open while you work?
Just the room being resealed is out of use. Rooms go back into use once the sealant has cured and we start the next.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Are you CHAS accredited?
Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.
What sealant do you use in washrooms?
An anti-mould sanitary silicone for most washroom joints. We use neutral-cure versions on stone, some metals and near mirrors.
Do you work in hospitals, clinics and care homes?
We do. Your infection-control rules, estates requirements and permits are followed. The work is phased around patients or residents.
