What happens if it’s left?
Washrooms shape how visitors judge a building. Visitors notice black sealant before they notice much else. Resealing is a modest task with a very visible payoff. Failed sealant in a building in Duckett's Green can quickly affect neighbours, tenants or the floor below: water travels through shared structures, and a small leak becomes a dispute between occupiers. Putting it right early is less disruptive than dealing with the consequences.
What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a quote when you are ready.

Washroom sealing in Duckett's Green
In a commercial washroom, sealant is typically the first thing to wear out. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning and mould that roots into it can’t be cleaned away. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. The enquiries we see most involve sealant laid over old silicone and now peeling and failed joints along IPS and cubicle panels, on accessible toilets and changing rooms, urinals and WCs and kitchens and tea points. For commercial sealant work in Duckett's Green, you deal with one contact from quote to sign-off, whether it’s one building or several.
Many London buildings can’t close every toilet at once. We work through washrooms floor by floor or core by core, at times agreed with you, so staff and visitors can always find an open washroom.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

What affects the price in Duckett's Green
A fixed quote reflects the actual work. It allows for:
- Quantities, in metres or numbers
- Which sealant the job calls for
- Location, for remote and island sites
- How much existing material needs removing
The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
Details that help us quote
A few photos plus some basic facts will normally do. It helps to include:
- Drawings or a marked-up plan, if available
- Anything awkward about access or site hours
- Any dates the work must fit around
- Any specification or named product
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to speak to us on 01277 525 020 or send photos by email with what you know.
General trades versus a specialist
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.
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
Diagnose, treat, sign off
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Most London premises stay occupied while we are on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
- The phasing is agreed so there are always facilities open.
- Failed silicone is removed completely and the surfaces cleaned of every trace.
- Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
- New sanitary silicone with anti-mould additives goes in and is tooled neat.
- Each room is handed back once the sealant has had its cure time.
Before we start on site
- Confirm the product named in the specification
- Tell us what induction or permit system the site runs
- Let building users know which areas are affected

Advice
Common questions from Duckett's Green clients
Can work at a site such as American University in London fit around teaching?
Yes, holiday working periods are the norm on campus jobs. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is hospital work, at somewhere like St Ann's Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.
How do we ask for a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.
Can washrooms stay open while you work?
Only the area we are working in is closed. Rooms go back into use once the sealant has cured and we start the next.

What about RAMS and site documents?
Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
