Smaller places such as New Street still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

Do you need washroom sealing in New Street?
Decorators’ caulk and general sealants sometimes end up where sanitary silicone belongs. They don’t stand up to constant water, and they stain, crack or wash out.
Things that usually lead to an enquiry:
- Mould spotting along silicone joints
- Discoloured joints around urinals and WC pans
- Panel joints letting water behind
- Stained or open joints at kitchen sinks and worktops
Pupil toilets at schools like Culverstone Green Primary School take heavy daily use, and the holidays give the window to reseal.

Keeping the joints sound
Keep the joints in good shape with a few simple steps:
- Tell us about infection-control or permit rules before we quote
- Respect the cure time before reopening each room
- Photograph and log failed joints across the estate
- Report split joints at trays and basins early
Ask your cleaning team to use gentle products and soft cloths on sealant. Strong acids, solvents and scourers wear the surface and give mould a start.
Inspectors look at whether kitchen surfaces can be kept clean. Resealing sinks, worktops and splashbacks before an inspection is a simple step.
How a job runs
On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, and the work typically takes between a morning and a week or so, set by the number of rooms and the phasing you need. For a building around New Street, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.
- We agree which washrooms close and when.
- Anything behind the joints that needs another trade is flagged.
- Failed sealant and residue are stripped out.
- We reseal with the grade suited to each area.
- We confirm reopening times for each washroom.
Getting the site ready
- Arrange parking or a loading space
- Tell us which areas need to stay in use
- Tell us your opening times and when work is allowed
Getting a fixed quote
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, photographs and a description will do.

What else we do in New Street
Toilets, showers and kitchens around New Street
New Street lies roughly 21 miles out from central London, in a commuter belt where offices and business parks are common. Office washrooms on business parks see heavy weekday use, so we phase work to keep some facilities open.
Where you are responsible for a hall attached to a building such as Church of Saint Peter, its kitchen and toilets need sealant that stays cleanable. Welfare facilities in units on estates such as Bowes Industrial Centre, 0.9 miles to the north-east of New Street, have showers, toilets and kitchens with sealant that works hard.

How the job changes by surface
IPS and cubicle panels
Panel systems meet walls, floors and vanity tops at sealed joints. They stop water reaching the panel boards.
Changing rooms and gyms
Changing rooms in gyms and leisure centres stay wet and warm so sealant there works very hard. Anti-mould sanitary silicone is the standard choice.
Your questions answered
What site paperwork comes with a job in New Street?
We’ll confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We hold £5m public liability insurance, are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded.
Will all the washrooms in our New Street building be closed at once?
Usually only some of them, for a short time. We work in phases so other facilities stay open. Sanitary silicone needs time to cure before the area is used, and we’ll tell you how long for the product used.
Which silicone is right for commercial washrooms?
It depends on the joint. Most washroom joints take sanitary silicone, and food areas take a hygienic, food-safe sealant where food contact is possible.
How long does a job like this take?
That varies with the scale of the job, but the work usually takes a morning or so for a small washroom, longer where showers and changing rooms are included. For bigger or phased jobs, we’ll set out a timescale with the quote.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Who decides which product is used?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Are you CHAS accredited and on Constructionline?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
