Washroom sealing in Southcourt, done properly

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. In food areas, hygienic or food-safe sealants are used where food contact is possible. If you are dealing with open joints along basins and vanity units and resealing that didn’t last because the old bead stayed, we can put it right, on IPS panels and cubicles, accessible toilets and changing rooms and urinals and WCs alike. Whoever orders the work in Southcourt, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

In and around places like Southcourt, hospitality kitchens and toilets see heavy use in busy spells. Smooth, sealed joints at worktops, sinks and wall cladding make cleaning easier, using a food-safe product near food preparation.

Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

From enquiry to sign-off

Site rules come first: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Work in places the size of Southcourt is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. The phasing is agreed so there are always facilities open.
  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. New sanitary silicone with anti-mould additives goes in and is tooled neat.
  6. You get a reopening time for every room, with signage left up until then.

Before we start on site

  • Send your site hours and access windows
  • Move anything stored against the joints
  • Point out any areas we must not close

Related advice

For managing agents and facilities managers

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

Building owners and managing agents use us on everything from one building to a spread of sites around Southcourt. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Questions we’re asked in Southcourt

Can you work around term dates at a campus such as University Campus Aylesbury Vale?

Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Must a hotel around Southcourt close while you work?

Rarely, if ever. We take a few rooms out at a time. We agree the order of rooms and the timings with you before we start.

What sealant do you use in washrooms?

Sanitary silicone with anti-mould additives in most cases. We use neutral-cure versions on stone, some metals and near mirrors.

Does weather matter for sealant work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Is colour matching possible?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

Is it possible to just clean mouldy silicone?

Usually not. The mould is inside the silicone, so it comes back however often it’s cleaned. Replacing the bead is the lasting answer.

Can you work to our specification?

Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.

When it isn’t the sealant

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Vanity carcasses that have swollen
  • Water from plumbing, not from a joint
  • Fittings that move too much to hold a bead

If you are not sure, just phone 01277 525 020 or send photos by email and we’ll give you a straight answer.

Joints and surfaces we work on

  • Urinals and WCs
  • Kitchens and tea points
  • Accessible toilets and changing rooms
  • Vanity units and basins
  • Showers, trays and wet room floors
  • IPS panels and cubicles

What sets the cost

Before we quote, we look at:

  • How accessible the joints are
  • Which sealant the job calls for
  • The size and state of each joint
  • How much there is to seal

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

What we need to price the job

A few photographs plus some basic facts will normally do. Please tell us:

  • The site address and postcode
  • Photos of the joints, close up and from further back
  • The asbestos register, for older buildings
  • Any dates the work must fit around

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, ring 01277 525 020 or email drawings and photos.

Why deal with it now?

Gaps and mould in joints give dirt and bacteria somewhere to sit, and in kitchens, clinics and schools that is a real concern. Sound, smooth joints are much easier to keep clean. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.

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

Why us?

  • Work carried out by CSCS-carded applicators
  • A fixed quote before work starts
  • Colour options checked against the specified product
  • Workmanship guaranteed for 12 months

When to bring in a specialist

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
