How we handle washroom sealing in St Nicholas
Facilities managers, contractors and building owners have used us for washroom sealing for over 20 years. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. There is public liability insurance behind every job. Every resealed washroom carries our 12-month guarantee. Most enquiries involve discoloured joints around urinals and WC pans and shower tray joints that have opened up, on kitchens and tea points, showers, trays and wet room floors and accessible toilets and changing rooms. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in St Nicholas it comes down to the same thing: the right product in a properly prepared joint.
Pub and restaurant kitchens around smaller places like St Nicholas work hard on their joints. Smooth, sealed joints at worktops, sinks and wall cladding make cleaning easier.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

After the work
To get the most from the new sealant:
- Keep washrooms out of use until we say the sealant has cured
- Tell us about infection-control or permit rules before we quote
- Report split joints at trays and basins early
- Squeegee showers and trays after busy periods
We hand each area back once the silicone has had the cure time the product needs. We’ll tell you when the wet areas can be used, and it helps if signs stay up until then.
In food areas, cleanability is something environmental health officers look at. Resealing sinks, worktops and splashbacks before an inspection is a simple step.
From enquiry to sign-off
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in 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. What matters most for a job in St Nicholas is a clear list of what needs doing. A fixed quote follows.
- First, the phasing is agreed so facilities stay open.
- Leaks, loose panels or damp are pointed out first.
- Old sealant is stripped and the faces prepared.
- The right sanitary or food-safe sealant is applied.
- We confirm reopening times for each washroom.
What we need from you
- Warn occupants and staff about the work
- Tell us which areas need to stay in use
- Point out parking and an unloading spot

Related advice
Should maintenance staff do it?
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Common problems we fix in St Nicholas
Cubicle panels, IPS panels and vanity units flex when people lean on them or doors are slammed and trays shift slightly with each user. A bead that can’t cope with the movement splits along one edge.
Any of the following is a good reason to get the joints checked over:
- Failed joints along IPS and cubicle panels
- Sealant laid over old silicone and now peeling
- Black mould inside silicone joints that cleaning can’t shift
- Washrooms that look worn because of the sealant
For a school such as The Leys Primary and Nursery School, washroom and kitchen sealant can be renewed around term dates.

What sealant work can’t fix
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:
- Loose panels, vanity units or tiles, which need fixing first
- Panel boards already damaged by water
- Water from plumbing, not from a joint
Not sure which it is? You can call the office on 01277 525 020 or email a schedule or drawings and we will tell you honestly.
What we seal
- IPS panels and cubicles

Your questions answered
Is a hospital such as Lister Hospital somewhere you can work?
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 Nicholas too small for you to travel to?
Not at all. St Nicholas is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
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 will confirm the colours available for the specified product.
How soon can a washroom be used after resealing?
The silicone needs time to cure before water reaches it. We plan the phasing around that so there are always rooms open.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
Are your applicators CSCS-carded?
Yes. Should the site need card details in advance, let us know and we will send them with the quote.

Why it’s worth doing now in St Nicholas
Bleaching black sealant may lighten it for a few days, but the mould is rooted in the silicone and comes back. A full reseal deals with it and your cleaning team stops chasing it. For buildings in places like St Nicholas, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.
Why appoint us
- Our applicators hold CSCS cards
- Old sealant cut out, never sealed over
