About our washroom sealing in Magdalen Laver

In a busy washroom, the sealant normally 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. We strip it out and lay new anti-mould sanitary silicone. If you’re dealing with black mould inside silicone joints that cleaning can’t shift and resealing that didn’t last because the old bead stayed, we can help, on IPS panels and cubicles, urinals and WCs and vanity units and basins alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Magdalen Laver, that means joint design, primers and backing rod as standard.

Halls and community buildings near places like Magdalen Laver 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.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Leave it or put it right?

A tired washroom says a lot about how a building is run. Guests, clients, pupils and patients notice stained joints even when the room is otherwise spotless. Resealing is a modest task with a very visible payoff. Around Magdalen Laver, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

Commercial clients in Magdalen Laver

For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first.

Your questions answered

Must every washroom in our Magdalen Laver building shut while you work?

Usually only some of them, for a short time. We work in phases so other facilities stay open. Sanitary silicone needs time to cure before the area is used, and we will tell you how long for the product used.

Is hospital work, at somewhere like St. Margaret's Hospital, something you do?

Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.

What sealant do you use in washrooms?

An anti-mould sanitary silicone for most washroom joints. Neutral-cure grades are used where acetoxy types could mark metals, stone or mirror backings.

How long before the toilets can reopen?

The silicone needs time to cure before water reaches it. Phasing is planned with the cure time in mind so there are always rooms open.

Is it OK to put new silicone on top of the old?

The whole of the old bead is removed and the surfaces cleaned before resealing. It’s the difference between a joint that lasts and one that peels.

Can one quote cover more than one building?

Yes. Several buildings can share a single quote, with one point of contact.

What do you charge?

There isn’t a price list, as every site differs. Send photos or drawings and we will price it at a fixed figure.

Magdalen Laver lies roughly 21 miles out from central London, in a commuter belt where offices and business parks are common. Washrooms in commuter-belt offices take constant weekday traffic, so we phase work to keep some facilities open.

For buildings on a site such as Hastingwood Business Centre, 1.2 miles west of Magdalen Laver, washrooms and tea points can be resealed in phases through the working week. For a hall at a building such as Parish Church of St Mary Magdalen, resealing the kitchen and toilets can be fitted between bookings. For a site such as St. Margaret's Hospital, 4.3 miles south-west of Magdalen Laver, sanitary joints in clinical areas need sound, cleanable sealant and a careful method.

Keeping the joints sound

A few simple habits keep the new joints working:

  • Don’t leave an open joint at a basin or tray
  • Tell us about infection-control or permit rules before we quote
  • Leave signs up until the cure time is over
  • Report faulty extraction promptly

Each room goes back into use only when the sealant has cured enough. We will tell you when the wet areas can be used and signage stays in place until that time.

In food areas, cleanability is something environmental health officers look at. Failed sealant around sinks and worktops is easy to put right in good time.

How a job runs

Site rules come first: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, we take the joints in the sequence agreed with you. For work around Magdalen Laver, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.

  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. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. You get a reopening time for every room, with signage left up until then.

Getting the site ready

  • Arrange parking or a loading space
  • Send asbestos survey details if the building is pre-2000
  • Share your working hours and any access restrictions

Surface by surface

Basins and vanity tops

Stone and some composite tops need a neutral-cure sealant and we choose a neutral-cure grade for them.

Kitchens and tea points

Kitchen joints need to be smooth and sealed so they can be cleaned properly. Food-safe sealants are used where food may touch the joint.

When to bring in a specialist

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
