Need washroom sealing in Nunhead?
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Should maintenance staff do it?
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
General builders and handymen seal joints, but it isn’t their main trade. 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.
About our washroom sealing in Nunhead
In healthcare and care settings, sealing is part of keeping surfaces cleanable. We work to your organisation’s estates and infection-control requirements and any site permits. Tell us what records you need and we’ll confirm with the quote. Site teams most often ask us about failed sealant in a tea point or staff kitchen and split or peeling sealant at shower trays, across IPS panels and cubicles, urinals and WCs and vanity units and basins. For commercial sealant work in Nunhead, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Restaurants, cafés and hotel kitchens across London have joints at worktops, sinks and wall cladding that need to stay smooth and cleanable. We use sanitary and hygienic sealants, choosing food-safe products where food may touch the surface.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Common problems we fix in Nunhead
Daily commercial cleaning wears sealant faster than people expect. Harsh products, abrasive pads and pressure washing break down a joint’s surface and edges so grime sticks to the damaged surface.
Typical triggers for a call:
- Discoloured joints around urinals and WC pans
- Users noticing mouldy joints
- Panel joints letting water behind
- Sealant lifting along a tray edge
Student showers at universities like King's College London, 1.8 miles west of Nunhead, see more use than most, and their silicone shows it.

Advice
After the work
Cleaning and maintenance staff play a part too. Pass these on to them:
- Respect the cure time before reopening each room
- Clear standing water from shower floors where possible
- Report split joints at trays and basins early
- Mention any site permits or estates rules at quote stage
Add washroom sealant to routine inspections. Look for black spotting, cracks, peeling edges and gaps at the busiest fittings and log what you find.
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.

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.

What sets the cost
We price every job individually. The main factors are:
- How accessible the joints are
- How much existing material needs removing
- Site requirements such as inductions and permits
- The total length or number of joints
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.
What we need to price the job
For an accurate fixed quote, we need a clear picture of the site. Send us:
- Photos of the joints, close up and from further back
- Specification clauses that apply
- Anything awkward about access or site hours
- Where the site is, with the postcode
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.
FAQs: Nunhead
Do you work in occupied care homes around Nunhead?
Yes. We agree rooms and times with the manager and work a few areas at a time. Any site rules, from signing in to infection control, are agreed before we start.
Can you cope with the access rules in a London building?
Yes, we plan every London job around the building’s own access rules. Share the building’s contractor rules and we’ll work to them. We allow for the ULEZ, which covers every borough
Do you have public liability insurance?
Yes. We’re fully insured, and the certificate can go with your quote.
Do you do washroom sealing in healthcare settings?
We do. Your infection-control rules, estates requirements and permits are followed. The work is phased around patients or residents.
Do you use special sealant for toilets and showers?
Each area gets the grade that suits it. Washrooms and showers take anti-mould sanitary silicone, and food areas take a hygienic, food-safe sealant where food contact is possible.
Do your applicators hold CSCS cards?
Yes. Should the site need card details in advance, let us know and we will send them with the quote.
Can you clean the mould off instead of resealing?
Surface cleaning won’t reach mould that has rooted into the bead. We replace the sealant with an anti-mould sanitary grade and point out if ventilation is part of the problem.
Why deal with it now?
When a washroom looks worn, a refit isn’t the only answer. Where tiles, panels and fittings are sound, new sealant may be enough to put it right while bigger works are planned. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
