Washroom sealing for Compton sites

Washroom sealing in Compton

In a busy washroom, the sealant usually gives up long before the tiles or fittings. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day and mould that roots into it can’t be cleaned away. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. If you’re dealing with shower tray joints that have opened up and resealing that didn’t last because the old bead stayed, we can help, whatever the surface. For commercial sealant work in Compton, you deal with one contact from quote to sign-off, whether it’s one building or several.

Halls and community buildings near places like Compton are used by different groups through the week, and their toilets and kitchens show it. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.

The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Compton is about 50 miles from central London, within the office belt around the capital. Office toilets in the commuter belt are in use from first arrivals to last departures, so we work a block of facilities at a time.

Pupil toilets at schools like Compton C.E. Primary School take heavy daily use, and the holidays give the window to reseal.

Should maintenance staff do it?

Redoing a failed joint normally costs more than getting it right at the outset, 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.

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.

Our process

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For work around Compton, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. We inspect each washroom and record the joints to be resealed.
  2. The fixed quote sets out the rooms, the products and the phasing.
  3. The whole of the old bead is removed.
  4. Each joint is cleaned and left dry.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Each area is handed back when ready.

What sets the cost

We price every job individually. The main factors are:

  • Phasing around occupants
  • The product specified
  • Distance, for remote addresses
  • Site requirements such as inductions and permits

A quote for washrooms and wet areas depends on how many there are, their condition and the access. Ask us for a fixed quote.

Details that help us quote

Good information means a firmer quote. When you get in touch, include:

  • The site address and postcode
  • Drawings or a marked-up plan, if available
  • Your programme or deadline
  • Any specification or named product

Do you need washroom sealing in Compton?

Commercial cleaning is harder on sealant than everyday use. Harsh products, abrasive pads and pressure washing break down a joint’s surface and edges so grime sticks to the damaged surface.

It’s worth sending us details if you spot any of the following:

  • Discoloured joints around urinals and WC pans
  • Washrooms that look worn because of the sealant
  • Failed sealant in a tea point or staff kitchen
  • Failed joints along IPS and cubicle panels

Church halls and community buildings, such as those at Church of St Mary and St Nicholas, have kitchens and toilets used by many groups, and their sanitary sealant works hard.

How to choose a sealant contractor

Common questions from Compton clients

Must every washroom in our Compton building shut while you work?

Not all at once. We take one block of facilities at a time. Sanitary silicone needs time to cure before the area is used, and we will tell you how long for the product used.

Is a smaller place like Compton outside your area?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

What will the job cost?

Every job gets its own fixed quote. To get one, give us a call on 01277 525 020 or email drawings and photos with a description of the work.

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.

Can washrooms stay open while you work?

Only the area we are working in is closed. Rooms go back into use once the sealant has cured, then we move on.

Is old silicone taken out first?

The failed bead is always removed. Fresh silicone can’t key to an old bead, so sealing over it soon peels.

Are you fully insured?

Yes. We’re fully insured, and the certificate can go with your quote.

Surface by surface

Showers and trays

A tray flexes every time it’s used and is constantly wet. Tray joints are where many washroom leaks start.

Changing rooms and gyms

Changing rooms in gyms and leisure centres stay wet and warm so sealant there works very hard. We use anti-mould sanitary silicone throughout.

What we can’t put right

Being straight saves everyone time. New sealant won’t cure:

  • Failed tanking beneath a wet-room floor or behind tiles
  • Vanity carcasses that have swollen
  • Water from plumbing, not from a joint

Not sure which it is? You can speak to us on 01277 525 020 or email the details over and we’ll tell you honestly before you book.
