How we handle washroom sealing in Catslip
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. Every resealed washroom carries our 12-month guarantee. If you’re dealing with gaps where vanity tops meet the wall and discoloured joints around urinals and WC pans, we can help, whatever the surface. Most enquiries from Catslip start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
Smaller places such as Catslip still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Sealant that has gone black with mould normally can’t be cleaned, so it is cut out and replaced.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

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.
Certain joints really need a specialist: 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.

What else we do in Catslip
Commercial washrooms in Catslip
Catslip is about 38 miles from central London, in a commuter belt where offices and business parks are common. Business park offices have washrooms in daily use by staff, and resealing in phases keeps facilities available.
For a school such as Nettlebed Community School, washroom and kitchen sealant can be renewed around term dates. At a hotel such as The White Hart Hotel, 0.5 miles to the west of Catslip, the quieter weeks are the time to reseal bathrooms.

Looking after the joints
Problems stay small when the joints are checked regularly. In particular:
- Squeegee showers and trays after busy periods
- Keep a record of which washrooms need attention
- Respect the cure time before reopening each room
- Share your site rules when you send details
Where possible, have shower floors and trays squeegeed after busy periods. Standing water on a joint all day shortens its life.
Leaks through tray and wet-floor joints can go unseen until a ceiling marks below. At that stage, boards or ceilings may need repair, so reseal when you first spot a split.
Your questions answered
Is a smaller place like Catslip outside your area?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
What documents will you need to give us for a job in Catslip?
We’ll confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.
What sealant do you use in washrooms?
An anti-mould sanitary silicone for most washroom joints. Neutral-cure grades are used where acetoxy types could mark metals, stone or mirror backings.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
Can you quote from photos?
Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit before quoting.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
Does weather matter for sealant work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
What happens if it’s left?
Washrooms shape how visitors judge a building. Visitors notice black sealant before they notice much else. Fresh sanitary silicone lifts a room with very little disruption. Halls, stores and units around places like Catslip may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Diagnose, treat, sign off
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes between a morning and a week or so, set by the number of rooms and the phasing you need, and our waste is bagged and taken away as we go. If others near Catslip need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- 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.
- We strip out the old bead and clean off the residue left behind.
- 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.
Preparing the site

- Point out any areas we must not close

Signs you need washroom sealing in Catslip
Panels and vanity units move slightly in use, and shower trays shift under foot. A bead that can’t cope with the movement splits along one edge.
Look out for the following:
- Gaps where vanity tops meet the wall
- Shower tray joints that have opened up
- Panel joints letting water behind
- Failed sealant in a tea point or staff kitchen
Church halls and community buildings, such as those at Church of St Bartholomew, have kitchens and toilets used by many groups, and their sanitary sealant works hard.
What your quote should include
- Is the sealant right for the movement and the substrate?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Are they CHAS accredited or on Constructionline?
- What level of public liability insurance do they hold?
