About our washroom sealing in Rowstock
Black spotting along a sealant bead is not a cleaning problem. The mould has rooted into the silicone itself, which is why it comes back however often it is treated. Replacing the bead is the lasting treatment. Site teams most often ask us about black mould inside silicone joints that cleaning can’t shift and split or peeling sealant at shower trays, on vanity units and basins, urinals and WCs and showers, trays and wet room floors.

Our process

Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. For work around Rowstock, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.

Site staff or a sealant specialist?
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
What affects the price in Rowstock
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- Location, for remote and island sites
- Which sealant the job calls for
- How accessible the joints are
- Quantities, in metres or numbers
Pricing washrooms and wet areas depends on how many there are, their condition and the access. Call for a quote.
Sending details for a quote
There’s no need for a formal survey. These details are enough to start:
- Specification clauses that apply
- Asbestos survey details if the building is older
- Any dates the work must fit around
- The postcode of the building
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to call the office on 01277 525 020 or send photos by email with what you know.
Different surfaces, different methods
IPS and cubicle panels
Panels flex slightly in use, so the sealant has to take that movement. We check fixings before sealing.
Basins and vanity tops
Basin joints get wet every time someone washes their hands, so the wall joint and bowl surrounds tend to fail before anything else. We remove the old bead and lay a fresh one of sanitary silicone.
Commercial washrooms in Rowstock
Several hotels sit less than 2 miles from Rowstock. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. The work can go floor by floor, agreed with housekeeping. Rowstock has three care or nursing homes no more than 2 miles away. Care home wet rooms and en suites are used every day and cleaned hard, which tells on the silicone. Rooms are done a few at a time at times agreed with the home.
Healthcare washrooms on sites such as Didcot Hospital, 2.2 miles to the east of Rowstock, are resealed area by area, under the site’s own infection-control rules. At a school such as Harwell Primary School, changing rooms and kitchens need cleanable joints as much as the toilets. Church halls and community buildings, such as those at Church of St Matthew, have kitchens and toilets used by many groups, and their sanitary sealant works hard.
Rowstock is about 3 miles west of Didcot, in Oxfordshire. Across the OX11 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed.

Common questions from Rowstock clients
Is hospital work, at somewhere like Didcot Hospital, something you do?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Can work in a care setting near Rowstock go ahead while residents are there?
Yes. Care settings are planned area by area, at times agreed with the home. Noise and disruption are kept to a minimum.
Which silicone is right for commercial washrooms?
An anti-mould sanitary silicone for most washroom joints. We use neutral-cure versions on stone, some metals and near mirrors.
Who decides which product is used?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit before quoting.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Can you send site paperwork?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
