Washroom sealing for commercial buildings in Flansham
Accessible toilets, shower rooms and changing rooms have joints that work harder than most: shower trays, wet-room floor edges, basins and floor-to-wall junctions. Gaps in those places let water get under the floor or behind panels so they get particular attention. If you’re dealing with open joints at the base of cubicle panels and black mould inside silicone joints that cleaning can’t shift, we can help. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Flansham is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Community buildings around smaller places like Flansham have kitchens and toilets used by many people. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

Keeping the joints sound
Keep the joints in good shape with a few simple steps:
- Clear standing water from shower floors where possible
- Don’t leave an open joint at a basin or tray
- Avoid scourers and harsh descalers on silicone
- Keep extract fans working and vents clear
Squeegeeing showers and trays after heavy use helps. Standing water on a joint all day shortens its life.
A split joint at a shower tray can leak for a long time before anyone sees it. By then, other trades may be needed as well, so reseal when you first spot a split.
From enquiry to sign-off
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Jobs in and around smaller places like Flansham are normally 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.
- Each area is handed back when ready.
Getting the site ready
- Clear stock, furniture or equipment away from the joints

What sealant work can’t fix
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Hollow tiles or loose panels behind the joint
- A room that stays damp because ventilation isn’t working
- Panel boards already damaged by water
Not sure which it is? You can give us a call on 01277 525 020 or send details through our quote form and we’ll tell you honestly before you book.
Surfaces we seal
- Vanity units and basins
- Accessible toilets and changing rooms
- Showers, trays and wet room floors
- IPS panels and cubicles
- Urinals and WCs
- Kitchens and tea points
Work for main contractors and building owners
As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
Site staff or a sealant specialist?
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
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.
Questions we are asked in Flansham
Is Flansham off your patch?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Can you work around term dates at a campus such as University of Chichester (Bognor Campus)?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
How do we ask for a quote?
You can use the quote form on this site; alternatively, call the office on 01277 525 020 or use the quote form. Include photographs or drawings if you have them.
Do you take on multi-site work?
Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.
Do your applicators hold CSCS cards?
Yes. If you need card details for site access, let us know and we will send them with the quote.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Sanitary sealant for Flansham buildings
The sea is no more than about 2 miles from Flansham, 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 2 miles around Flansham include five care or nursing homes. In a care setting, a mouldy or lifting joint in a wet room is a hygiene issue as much as a cosmetic one. Each room is kept out of use only as long as the sealant needs.
Staff changing rooms and patient toilets at places like Bognor Regis War Memorial Hospital, 1.7 miles to the south-west of Flansham, need cleanable, sound silicone. Hotels such as Ancton House Hotel (to the east of Flansham) have en suite bathrooms where tired silicone at the bath, tray and basin is replaced room by room.

Signs you need washroom sealing in Flansham
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.
Typical triggers for a call:
- Failed joints along IPS and cubicle panels
- Stained or open joints at kitchen sinks and worktops
- Shower tray joints that have opened up
- Stained sealant around pans and urinals
For a hall at a building such as Bilsham Chapel, resealing the kitchen and toilets can be fitted between bookings.
