About our washroom sealing in Winchelsea

In a commercial washroom, sealant is normally the first thing to wear out. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day, and once mould grows into it, it can’t be scrubbed out. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. The enquiries we see most involve shower tray joints that have opened up and discoloured joints around urinals and WC pans, across accessible toilets and changing rooms, showers, trays and wet room floors and vanity units and basins. Searching for sealant specialists in Winchelsea? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

In and around smaller places like Winchelsea, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Surface by surface

Basins and vanity tops

Natural stone tops can be marked by acetoxy silicone and we choose a neutral-cure grade for them.

Urinals and WC pans

We reseal around urinals and pans with a sanitary grade once the whole of the old bead has gone.

Keeping Winchelsea washrooms open while we work

Winchelsea sits close to the coast, within about 2 miles, and places by the sea often rely on visitors, so their hotels and holiday lets see heavy seasonal use. Heavy seasonal use is hard on shower and basin sealant, so resealing in the quieter months keeps rooms ready. A 2-mile radius around Winchelsea takes in a number of hotels. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time.

For an occupier at a site such as Jempson Trading Estate (1.8 miles north-east of Winchelsea), the canteen and welfare facilities need cleanable joints as much as any office. Schools such as St Thomas' Church of England Aided Primary School have toilets, changing rooms and kitchens that are best resealed in the holidays. Where you are responsible for a hall attached to a building such as The Parish Church of St Thomas the Martyr, its kitchen and toilets need sealant that stays cleanable.

Before we quote, we look at:

  • Travel to remote or island sites
  • Site requirements such as inductions and permits

  • Whether an asbestos survey exists
  • Specification clauses that apply
  • Photos of the joints, close up and from further back
  • What the building is and how it’s used

Your questions answered

Is a smaller place like Winchelsea outside your area?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Will the toilets in our Winchelsea building be out of use?

Rarely all at once: work is phased so some facilities are always available. Sanitary silicone needs time to cure before the area is used, and we’ll tell you how long for the product used.

Can you quote from photos?

Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.

Will cleaning remove black mould from sealant?

Not for long. Mould grows into the sealant itself so cleaning only lightens it for a while. Replacement is the lasting fix.

When is resealing likely to be due?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

Is any job too small?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Why it’s worth doing now in Winchelsea

A tired-looking washroom doesn’t always need a refurbishment. If the finishes are in good order, replacing the sealant may do much of what’s needed while bigger works are planned. Around Winchelsea, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.

The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a quote when you are ready.
