How we handle washroom sealing in Headcorn

Our washroom work covers offices, hotels, schools and colleges, leisure centres and gyms, clinics and care homes, plus the kitchens and tea points that go with them. The products and the method are chosen for how heavily each space is used.

Whoever orders the work in Headcorn, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

General trades versus a specialist

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

For most general trades, sealant is a sideline. 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.

How a job runs

Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. For a job in Headcorn, the main thing is a clear picture of the work, so send photographs of each area. You will then get a fixed price for the work.

  1. Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
  2. We agree which rooms close and when, so users always have somewhere to go.
  3. We strip out the old bead and clean off the residue left behind.
  4. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  5. New sanitary silicone with anti-mould additives goes in and is tooled neat.
  6. Rooms reopen after the product’s cure time, and we move to the next.

Preparing the site

  • Tell staff and tenants when we will be in
  • Make sure the joints can be reached
  • Send asbestos survey details if the building is pre-2000

Units at estates like Barradale Farm Industrial Estate (1 mile north-west of Headcorn) have welfare blocks whose showers and toilets see shift after shift. Halls linked to places like St Peter's and St Paul's Church host groups all week, which is hard on kitchen and toilet sealant.

Questions about Headcorn

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

Not all at once. We take one block of facilities at a time. We’ll tell you the curing time for the product before we start.

Would you work within a site like Benenden Hospital?

Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.

What happens if old sealant might contain asbestos?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

What’s the quickest route to a quote?

You can use the quote form on this site; alternatively, give us a call on 01277 525 020 or send photos by email. Photos, drawings or a joint schedule help us quote quickly.

Can the sealant be colour-matched?

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 confirm what’s available for the specified product when we quote.

How many days will you need on site?

That varies with the scale of the job, though a typical visit normally takes a few hours for one toilet block, with bigger buildings phased across a number of visits. For bigger or phased jobs, we’ll set out a timescale with the quote.

Can you send site paperwork?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

Aftercare for building managers

A few simple habits keep the new joints working:

  • Keep washrooms out of use until we say the sealant has cured
  • Tell us about infection-control or permit rules before we quote
  • Don’t leave trays and floors sitting wet
  • Avoid scourers and harsh descalers on silicone

Ventilation is half the battle. A room that stays damp will grow mould on almost anything, so get faulty extract looked at.

Mouldy sealant only gets harder to ignore, and complaints follow. Dealing with it while it’s just the sealant keeps it simple.

Why it’s worth doing now in Headcorn

Cleaning mouldy sealant only masks it but the growth is inside the bead and returns. A full reseal deals with it and cleaners stop fighting a losing battle. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
