Washroom sealing for commercial buildings in Southwick
Since 2005 we have resealed commercial washrooms for facilities teams, contractors and building owners. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We are fully insured. Our workmanship is guaranteed for 12 months. The enquiries we see most involve sealant stained black around basins and showers and open joints at the base of cubicle panels, on showers, trays and wet room floors, IPS panels and cubicles and urinals and WCs. For commercial sealant work in Southwick, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
In a smaller place such as Southwick, commercial washrooms tend to be in schools, pubs, cafés, surgeries, care homes and sports clubs. They don’t need a big crew, but they do need old sealant fully cut out before anti-mould silicone goes on.
We stand by our work: 12 months, guaranteed. That covers our preparation and application.

Common problems we fix in Southwick
Warmth, moisture and soap residue are exactly what mould needs, and sealant joints trap all three. Anti-mould additives help, but in a poorly ventilated room mould can still take hold eventually.
Most enquiries start with something like this:
- Open joints along basins and vanity units
- A new bead over an old one coming away
- Black mould inside silicone joints that cleaning can’t shift
- Urinal joints that look unhygienic
Units at estates like Grange Industrial Estate (to the south-west of Southwick) have welfare blocks whose showers and toilets see shift after shift.
What your quote should include
- Will RAMS and insurance details be available?
- Will failed sealant be removed rather than covered?
- What the guarantee covers, and for how long
- Their public liability cover
When to bring in a specialist
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
What the job involves on each surface
Showers and trays
A tray flexes every time it’s used and is constantly wet. Tray perimeters are a frequent source of leaks.
Changing rooms and gyms
Changing rooms in gyms and leisure centres stay wet and warm, so mould is a constant battle. We use anti-mould sanitary silicone throughout.
What happens if it’s left?
Gaps and mould in joints give dirt and bacteria somewhere to sit, and in kitchens, clinics and schools that is a real concern. Sound, smooth joints are much easier to keep clean. In a smaller place such as Southwick, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

Busy facilities in and around Southwick
Southwick sits close to the coast, within about 1 mile, and places by the sea often rely on visitors, so their hotels and holiday lets see heavy seasonal use. Washrooms used guest after guest wear their sanitary silicone faster, so we plan the work for quieter weeks where possible. Southwick is about 46 miles from central London, in a commuter belt where offices and business parks are common. Washrooms in commuter-belt offices take constant weekday traffic, so we work a block of facilities at a time.
Where you’re responsible for a hall attached to a building such as St Michael and All Angels Church, its kitchen and toilets need sealant that stays cleanable. Toilets at places like Goldstone Retail Park, 2.7 miles east of Southwick, are cleaned constantly, so silicone needs to be sound and smooth.

- 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.
- Failed silicone is removed completely and the surfaces cleaned of every trace.
- 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.

- Tell us which areas need to stay in use

Questions we’re asked in Southwick
Is Southwick too far out for you?
No. Places such as Southwick are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Would you work within a site like Southlands Hospital?
Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.
Do you phase washroom resealing?
Only the area we’re working in is closed. Rooms go back into use once the sealant has cured, then we move on.
Is colour matching possible?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.
How many days will you need on site?
That varies with the scale of the job, though a typical visit usually takes a few hours for one toilet block, with bigger buildings phased across a number of visits. For bigger or phased jobs, we’ll set out a timescale with the quote.
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it.
