Need washroom sealing in Chartham?

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

How we handle washroom sealing in Chartham

Washroom joints need the right sealant, not whatever is to hand. Sanitary grades carry anti-mould additives, and neutral-cure versions avoid the damage acetoxy types can do to some metals, stone and mirror backings. Where food contact is possible, we use a hygienic, food-safe grade. If you are dealing with gaps where vanity tops meet the wall and panel joints letting water behind, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, in Chartham it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Farm shops, cafés and venues in converted rural buildings around places like Chartham have busy toilets and kitchens. Tell us your opening times and quiet periods and we will plan around them.

A 12-month guarantee applies to all our work. If an installation problem shows up, call the office on 01277 525 020 or email drawings and photos and we’ll arrange a return visit.

Questions about Chartham

Can work at a site such as University of the Creative Arts fit around teaching?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Is Chartham off your patch?

No. Places such as Chartham are covered as much as the big towns. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.

Do you have public liability insurance?

Yes. Our insurance certificate can be sent alongside the quote.

What site paperwork can you supply?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

How much does the work cost?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote.

Will cleaning remove black mould from sealant?

Cleaning may lighten it, but the mould returns. New anti-mould sanitary silicone is the treatment and check the ventilation isn’t the cause.

What sealant do you use in washrooms?

Sanitary silicone with anti-mould additives in the majority of cases. Neutral-cure grades are used where acetoxy types could mark metals, stone or mirror backings.

Site staff or a sealant specialist?

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

For managing agents and facilities managers

If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Chartham can sit alongside others in a wider programme.

Washroom sealing around Chartham: points for this area

At about 51 miles from central London, Chartham is within reach of the capital. Office washrooms on business parks see heavy weekday use, and resealing in phases keeps facilities available.

For a hall at a building such as Church of St Mary, resealing the kitchen and toilets can be fitted between bookings. Office washrooms on sites such as Stour Valley Business Park, 0.7 miles north-east of Chartham, are in use all working day, so resealing is phased to keep some open.

Chartham is about 3 miles south-west of Canterbury, in Kent. We send applicators to Chartham for washrooms and wet areas, handled exactly as we handle every other area. Chartham is one of 931 places in Kent on our list. There’s a separate page for London, roughly 51 miles from Chartham.

When to call us in Chartham

Decorators’ caulk and general sealants sometimes end up where sanitary silicone belongs. They aren’t made for constant wetting, and they stain, crack or wash out.

Site and facilities staff are often the first to spot these:

  • Open joints at the base of cubicle panels
  • Kitchen worktop joints that can’t be kept clean
  • Washrooms that look worn because of the sealant
  • Stained sealant around pans and urinals

Student showers at universities like University of the Creative Arts, 3.3 miles to the north-east of Chartham, see more use than most, and their silicone shows it.

What to look for in a quote

  • Whether old or failed sealant will be cut out, not overlaid
  • Their approach to joint depth and backing
  • Their pre-qualification and accreditations
  • Whether their applicators hold CSCS cards

Questions to ask before you appoint anyone

Different surfaces, different methods

Basins and vanity tops

Water getting past a vanity top joint can swell the board beneath. Prompt resealing keeps the unit sound.

Showers and trays

In staff, hotel and changing-room showers, the tray joint and wall corners take the hardest use. Every joint is stripped, degreased, dried and given a new bead.

How a job runs

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes half a day to a day per washroom, depending on the number of fittings, and we clear our waste as we work. If others near Chartham need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. A phasing plan keeps part of the building’s facilities in use at all times.
  3. We strip out the old bead and clean off the residue left behind.
  4. We clean and dry every surface so the new sealant can grip.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. You get a reopening time for every room, with signage left up until then.

What we need from you

  • Send asbestos survey details if the building is pre-2000
  • Let building users know which areas are affected
  • Explain the parking and delivery arrangements

Advice

When it isn’t the sealant

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Swollen or delaminated boards behind panels or vanity tops
  • Failed tanking beneath a wet-room floor or behind tiles
  • Loose panels, vanity units or tiles, which need fixing first

If in doubt, ring 01277 525 020 or send photos by email and we will say what we think.
