How we handle washroom sealing in Tower Hill
In a busy washroom, the sealant usually gives up long before the tiles or fittings. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day, and once mould grows into it, it can’t be scrubbed out. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. We work on kitchens and tea points, IPS panels and cubicles and urinals and WCs, and the usual reasons a site gets in touch are mould spotting along silicone joints and users noticing mouldy joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Tower Hill is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In a London area such as Tower Hill, commercial washrooms in offices, hotels and leisure buildings see constant use. Mouldy or split sealant at vanity tops, IPS panels and urinals is replaced with anti-mould sanitary silicone, in phases so some facilities stay open.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, call 01277 525 020 or email us and we will come back to it.

When it isn’t the sealant
We check first that sealant really is the fix. It isn’t the answer for:
- Water escaping beneath the floor rather than through a joint
- Loose panels, vanity units or tiles, which need fixing first
- Mould caused by poor ventilation, which will return until the extract is fixed
If you are not sure, just call the office on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.
What we seal
- Urinals and WCs
- IPS panels and cubicles

- Vanity units and basins
- Accessible toilets and changing rooms
- Showers, trays and wet room floors
What sets the cost
Quotes vary with the job. It mainly depends on:
- Any access equipment needed
- Distance, for remote addresses
- Whether the work must be split into stages
- How much there is to seal
Access often affects the price as much as the sealing: 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
A few photos plus some basic facts will normally do. Please tell us:
- Any specification or named product
- Rough lengths or quantities, or drawings if you have them
- A wide shot and a close-up of the area
- When you need the work done
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
After the work
To get the most from the new sealant:
- Brief cleaning staff to treat joints gently
- Include joints in routine washroom inspections
- Tell us about infection-control or permit rules before we quote
- Photograph and log failed joints across the estate
Squeegeeing showers and trays after heavy use helps. Standing water on a joint all day shortens its life.
Mouldy sealant only gets harder to ignore and users notice. Dealing with it while it’s just the sealant keeps it simple.
Washroom sealing around Tower Hill: points for this area
A 2-mile radius around Tower Hill takes in a good number of hotels. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. Rooms are done in turn so most stay available. In London buildings, toilets and showers generally need to stay partly open, so we take one block of facilities out of use at a time.
Staff changing rooms and patient toilets at places like London Bridge Hospital (less than half a mile south-west of Tower Hill) need cleanable, sound silicone. Halls of residence and teaching buildings at universities such as Northeastern University London, under half a mile to the south-east of Tower Hill, are easiest to reseal during vacations. Colleges such as London College of Marketing and Technology, 0.6 miles north-east of Tower Hill, have toilets, changing rooms and catering kitchens that can be resealed around term dates.

What the job involves on each surface
IPS and cubicle panels
IPS panels and cubicle systems have joints at the wall, the floor and the worktop. Those joints protect the boards behind from water.
Wet-room floors and floor-to-wall joints
Wet floors are common in accessible showers and changing rooms, so their perimeter joints get close attention.
Diagnose, treat, sign off
Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. In Tower Hill, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- Every room is surveyed and the failed joints listed.
- You get a fixed quote with the phasing plan.
- Old sealant is removed completely and the faces cleaned.
- Each joint is cleaned and left dry.
- A sanitary silicone bead is laid and given a smooth tooled finish.
- Rooms reopen after the cure time.
Before we start on site
- For older buildings, check the asbestos register before work
- Have the specification and drawings to hand
- Agree which areas must stay open
Getting a fixed quote

Why deal with it now?
Waiting for a holiday closure can leave failing joints in place for a long time. Phasing lets it happen now, with facilities kept in use. Failed sealant in a building in Tower Hill can quickly affect neighbours, tenants or the floor below. Putting it right early is less disruptive than dealing with the consequences.
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.
