Our process
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before the next one starts. In Herne 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 washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
- We agree which rooms close and when, so users always have somewhere to go.
- We strip out the old bead and clean off the residue left behind.
- Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
- 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.
Getting the site ready
- For older buildings, check the asbestos register before work
- Tell us your opening times and when work is allowed
- Let building users know which areas are affected

Washroom sealing for commercial buildings in Herne Hill
Washroom joints need the right sealant, not whatever is to hand. Sanitary grades carry anti-mould additives, and neutral-cure versions avoid the damage acetoxy types can do to some metals, stone and mirror backings. In food areas, hygienic or food-safe sealants are used where food contact is possible. We work on IPS panels and cubicles, urinals and WCs and showers, trays and wet room floors, and the usual reasons a site gets in touch are urinal joints that look unhygienic and kitchen worktop joints that can’t be kept clean. Whether you call it commercial sealant work, mastic application or joint sealing, in Herne Hill it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Restaurants, cafés and hotel kitchens across London have joints at worktops, sinks and wall cladding that need to stay smooth and cleanable. Hygienic and anti-mould sanitary sealants are used where they suit, with food-safe products where food contact is possible.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

How the quote is worked out
Your fixed quote is built from the real scope. It takes account of:
- Quantities, in metres or numbers
- Location, for remote and island sites
- Any access equipment needed
- How much existing material needs removing
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
What to include in your enquiry
We can often quote from photographs and a few details. It helps to include:
- Asbestos survey details if the building is older
- Any dates the work must fit around
- A wide shot and a close-up of the area
- What the building is and how it’s used
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.
When to bring in a specialist
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
Aftercare for building managers
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Keep washrooms out of use until we say the sealant has cured
- Squeegee showers and trays after busy periods
- Keep extract fans working and vents clear
- Keep a record of which washrooms need attention
Ventilation is half the battle. Constant damp lets mould take hold even on anti-mould grades so report fans that aren’t working to your building services team.
Mould in a joint spreads along the bead and into nearby grout and users notice. Replacing it early keeps the job to a reseal.
For managing agents and facilities managers
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.
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.
Honest limits
Being straight saves everyone time. New sealant won’t cure:
- Vanity carcasses that have swollen
- Leaking pipes, traps, wastes or cisterns, which need a plumber
- Failed tanking beneath a wet-room floor or behind tiles
If in doubt, speak to us on 01277 525 020 or email us and we will say what we think.

Washroom sealing around Herne Hill: what changes locally
In London buildings, toilets and showers generally need to stay partly open, so resealing goes floor by floor, agreed with the facilities team. Herne Hill has plenty of hotels close by, all within 2 miles. 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.
For a college such as William Booth College, 0.9 miles north of Herne Hill, half-term and summer give the windows for washroom work. Staff changing rooms and patient toilets at places like King's College Hospital (to the north of Herne Hill) need cleanable, sound silicone. At a university such as King's College London, which lies north of Herne Hill, summer is the usual window for resealing residence bathrooms.

Common questions from Herne Hill clients
Can you work in a London building with booked loading and goods-lift slots?
Yes. Inductions, permits and timed loading are routine for us in London. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it

In the majority of cases no closure is needed: we work room by room or floor by floor. Tell us your quiet periods and access windows and we will plan around them.
Do you hold CHAS accreditation?
Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
Do you take on small jobs?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
Can the sealant be colour-matched?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.
How long before the toilets can reopen?
Each sealant has a cure time before it should get wet. Phasing is planned with the cure time in mind so facilities are never short.
