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. Jobs in and around smaller places like Welborne are usually planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- Every room is surveyed and the failed joints listed.
- The fixed quote sets out the rooms, the products and the phasing.
- Old sealant is removed completely and the faces cleaned.
- Joints are degreased and dried.
- New anti-mould sealant goes in and is tooled neat.
- Rooms reopen after the cure time.
Before we start on site
- Send your site hours and access windows

Advice
About our washroom sealing in Welborne
In healthcare and care settings, sealing is part of keeping surfaces cleanable. We work to your organisation’s estates and infection-control requirements and any site permits. Any records you need are confirmed with the quote. We work on kitchens and tea points, IPS panels and cubicles and accessible toilets and changing rooms, and what we’re called in for most is urinal joints that look unhygienic and sealant lifting along a tray edge.

Questions we’re asked in Welborne
Could you schedule work at a campus like Fareham College for the vacation?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Is Welborne off your patch?
Not at all. Welborne is within our area. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Can you work to our specification?
Yes. Send it with your enquiry, and we will price the work to it, flagging anything that needs clarifying.
What site paperwork can you supply?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
Will you quote for a small job?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
Is colour matching possible?
That depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
Common problems we fix in Welborne
Washrooms are warm, damp and full of organic residue, and silicone joints hold onto all three. Even anti-mould grades can be colonised over time where extraction is poor.
If one of these sounds familiar, it’s time for a closer look:
- Washrooms that look worn because of the sealant
- Failed joints along IPS and cubicle panels
- Black mould inside silicone joints that cleaning can’t shift
- Shower tray joints that have opened up
For a hotel such as The King's Head Hotel (1.3 miles north of Welborne), resealing en suites a few rooms at a time keeps the rest available.
Before you book anyone
- The terms of the workmanship guarantee
- Will RAMS and insurance details be available?
- Health and safety accreditation such as CHAS
- Their public liability cover
Leave it or put it right?
A failed joint behind a basin or along a shower tray lets water run where it shouldn’t. That can lead to swollen boards, marked ceilings below and lingering smells which costs more to fix than a reseal. Older rural buildings around Welborne move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Commercial washrooms in Welborne
With the shore within about 3 miles, Welborne counts as a coastal location, and seaside hospitality usually has a peak season that works washrooms hard. Heavy seasonal use is hard on shower and basin sealant, so we plan the work for quieter weeks where possible. The area within 2 miles of Welborne holds several hotels. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time. We work a handful of rooms at a time, so the hotel keeps letting the rest.
At a college such as Fareham College, which lies south of Welborne, washroom and kitchen sealant is best renewed in the holidays or in phases during term. Office toilets at parks like Knowle Village Business Park, 0.7 miles to the west of Welborne, take steady weekday use, and mouldy silicone soon shows.
Welborne is about 2 miles north of Fareham, in Hampshire. Welborne sits inside our coverage and the rest of Hampshire, with the same fixed quotes and 12-month guarantee as everywhere else. Our Hampshire coverage takes in 723 places. Portsmouth is covered too, around 7 miles from Welborne.
We take on washrooms and wet areas across the PO17 postcode area, whatever the building. We also cover Crockerhill (1 mile east), Wickham Common (1 mile north-east), North Fareham (1 mile south-east), Hundred Acres (2 miles north-east) and Fareham (2 miles south) for washrooms and wet areas. Bigger towns within reach include Winchester (13 miles north-west), Gosport (6 miles south), Havant (9 miles east), Eastleigh (9 miles north-west), Horndean (8 miles east) and Totton (14 miles west).
What’s near Welborne
Locally, jobs take us to sites close to The Miners Arms. Welborne’s nearest station is Fareham station, roughly 1.9 miles south of the centre. A little further out are Carron Row Farm Museum (2.4 miles south-west) and Portchester Castle (4.5 miles south-east). Not far away are Portsdown Hill and Swanwick Lakes.
Cost factors for washrooms and wet areas
These are the things that shape the price:
- Working within restricted access windows
- Distance, for remote addresses
- How much there is to seal
- Whether old sealant has to be cut out first
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.
Details that help us quote
We can often quote from photos and a few details. It helps to include:
- Asbestos survey details if the building is older
- A wide shot and a close-up of the area
- Any specification or named product
- Approximate linear metres or a joint schedule
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, speak to us on 01277 525 020 or send details through our quote form.
When something else is needed
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Fittings that move too much to hold a bead
- Vanity carcasses that have swollen
- Condensation from failed extract fans
If you are not sure, just phone 01277 525 020 or use the quote form and we’ll give you a straight answer.
Joints and surfaces we work on
- Urinals and WCs
- Showers, trays and wet room floors
- Kitchens and tea points
- Accessible toilets and changing rooms
- IPS panels and cubicles
- Vanity units and basins

Keeping the joints sound
Once the work is signed off, these steps help:
- Inspect washroom sealant regularly
- Don’t leave trays and floors sitting wet
- Mention any site permits or estates rules at quote stage
- Keep extract fans working and vents clear
Where possible, have shower floors and trays squeegeed after busy periods. Standing water on a joint all day shortens its life.
Mould in a joint spreads along the bead and into nearby grout and users notice. Dealing with it while it’s just the sealant keeps it simple.
