Washroom sealing in St Leonards
You can’t shut every toilet in an office, school or hotel at once. We phase the work one washroom, one bank of cubicles or one changing room at a time, so staff, guests or pupils always have somewhere to go. Tell us your site hours and access windows and we’ll plan around them. Site teams most often ask us about failed sealant behind washroom basins and panel joints letting water behind, across showers, trays and wet room floors, urinals and WCs and kitchens and tea points. Looking for mastic applicators who cover St Leonards? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Community buildings around smaller places like St Leonards have kitchens and toilets used by many people. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant.

Should maintenance staff do it?
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Urinals and WC pans
Joints around urinals and WC pans take splashes, cleaning chemicals and knocks. Stained or split joints here trap smells and make the room look neglected.
Wet-room floors and floor-to-wall joints
We seal the visible joints; we don’t install or repair waterproofing below, and we will say if the trouble looks to be beneath the floor.

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area.

Leave it or put it right?
A tired washroom says a lot about how a building is run. Guests, clients, pupils and patients notice stained joints before they notice much else. Resealing is a modest task with a very visible payoff. One visit to deal with every failing joint makes more sense than several trips to a place like St Leonards. Send photos of each area and we will quote for the lot.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we’ll explain how it’s made up.

Washroom sealing around St Leonards: points for this area
Central London is about 31 miles from St Leonards. Office washrooms on business parks see heavy weekday use, so we work a block of facilities at a time.
Welfare facilities in units on estates such as Icknield Way Industrial Estate (2.6 miles north of St Leonards) have showers, toilets and kitchens with sealant that works hard. Where you’re responsible for a hall attached to a building such as Church of St Leonard, its kitchen and toilets need sealant that stays cleanable. Clinical washrooms at sites like Chiltern Hospital, 4.7 miles to the south of St Leonards, are scheduled with the ward so the room is out of use for as little time as possible.

Common questions from St Leonards clients
Do you take on work at healthcare sites like Chiltern Hospital?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is St Leonards too far out for you?
Not at all. St Leonards is within our area. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Which silicone is right for commercial washrooms?
Each area gets the grade that suits it. Washrooms and showers take anti-mould sanitary silicone while kitchens may need a food-safe grade.
What will the job cost?
There isn’t a price list, as every site differs. With photos or drawings, we can give you a fixed quote.
Is colour matching possible?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.
How do you choose the sealant?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
When something else is needed
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- A room that stays damp because ventilation isn’t working
- Fittings that move too much to hold a bead
- A dripping waste or valve behind a panel
Not sure which it is? You can give us a call on 01277 525 020 or use the quote form and we’ll tell you honestly before you book.
