How we handle washroom sealing in Copnor
In a busy washroom, the sealant usually 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. The enquiries we see most involve discoloured joints around urinals and WC pans and sealant laid over old silicone and now peeling, on urinals and WCs, vanity units and basins and kitchens and tea points. Most enquiries from Copnor start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
A place of Copnor’s size will typically have a few buildings with commercial washrooms: a school, a surgery, a pub or café, perhaps a care home. They don’t need a big crew, but they do need old sealant fully cut out before anti-mould silicone goes on.
Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

How the quote is worked out
Quotes vary with the job. Expect it to depend on:
- Which sealant the job calls for
- The total length or number of joints
- Site requirements such as inductions and permits
- Working within restricted access windows
The price depends on how many linear metres there are, what has to come out first and the access. Call for a quote once you have the details.

Busy facilities in and around Copnor
Copnor sits close to the coast, within about 1 mile, and coastal places often have hotels, guest houses and holiday accommodation with busy seasons. Bathrooms turned round daily in the busy months need sound, cleanable joints, and the quieter months are the natural time to reseal. A 2-mile radius around Copnor takes in plenty of hotels. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later.
En suites at hotels like The Avenue Hotel (1.2 miles north-west of Copnor) are cleaned daily, which wears silicone over time. Toilets at colleges like Portsmouth College, 0.8 miles east of Copnor, take heavy use from students and staff alike.
Copnor is about 1 mile east of Portsmouth, in Portsmouth. Businesses, contractors and managing agents in Copnor use us for work on washrooms and wet areas, as part of our coverage of Portsmouth. Our Portsmouth coverage takes in 19 places, large and small.

Your questions answered
Will you plan work around the academic year at somewhere like University of Portsmouth?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is a hospital such as St James Hospital somewhere you can work?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Are your applicators CSCS-carded?
Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Can one quote cover more than one building?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
Which sealant will you use?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
How many days will you need on site?
That varies with the scale of the job, though a typical visit typically takes a few hours for one toilet block, with bigger buildings phased across a number of visits. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Maintenance after handover
A few simple habits keep the new joints working:
- Tell us about infection-control or permit rules before we quote
- Act on the first split you see at a shower tray
- Note failing joints building by building
- Inspect washroom sealant regularly
Mild cleaning products and non-abrasive cloths look after sanitary silicone best. Strong acids, solvents and scourers wear the surface over time.
A few failed joints can be resealed with hardly any disruption. Left until every washroom is affected, it becomes a bigger programme and more closures to manage.

General trades versus a specialist
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
What we’re called out for in Copnor
Low-level joints get hit by mop buckets, cleaning trolleys and feet, especially at floor edges and around urinals and WC pans.
Site and facilities staff are often the first to spot these:
- Black mould inside silicone joints that cleaning can’t shift
- Failed sealant behind washroom basins
- Users noticing mouldy joints
- Kitchen worktop joints that can’t be kept clean
Halls of residence and teaching buildings at universities such as University of Portsmouth, 1.2 miles to the south of Copnor, are easiest to reseal during vacations.
