Washroom sealing in Walter's Ash, done properly

Not every silicone belongs in a washroom. Sanitary silicone contains additives that resist mould, 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. The enquiries we see most involve mould spotting along silicone joints and gaps where vanity tops meet the wall, across urinals and WCs, vanity units and basins and accessible toilets and changing rooms. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Walter's Ash is the same: the right product in a properly prepared joint.

In and around smaller places like Walter's Ash, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Cost factors for washrooms and wet areas

Before we quote, we look at:

  • Quantities, in metres or numbers
  • The size and state of each joint
  • Removal of failed or old sealant
  • Location, for remote and island sites

The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

What we need to price the job

It doesn’t need to be a full survey. These details are enough to start:

  • Your programme or deadline
  • Rough lengths or quantities, or drawings if you have them
  • Specification clauses that apply
  • Whether the building will be occupied during the work

A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or phone 01277 525 020 or send photos by email to discuss it first.

Our process

At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. Rural sites near Walter's Ash may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. Every room is surveyed and the failed joints listed.
  2. The fixed quote sets out the rooms, the products and the phasing.
  3. The whole of the old bead is removed.
  4. Joints are degreased and dried.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Each area is handed back when ready.

Before we start on site

  • Warn occupants and staff about the work
  • Send asbestos survey details if the building is pre-2000
  • Tell us which areas need to stay in use

Questions about Walter's Ash

Is a smaller place like Walter's Ash outside your area?

Not at all. Walter's Ash is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Can you work on a hospital site such as Wycombe 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.

Do you take on multi-site work?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

Are you CHAS accredited and on Constructionline?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Do you take on small jobs?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

Will you come and look before quoting?

That depends on the size and complexity of the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.

What sealant do you use in washrooms?

Each area gets the grade that suits it. Washrooms and showers take anti-mould sanitary silicone while kitchens may need a food-safe grade.

What the job involves on each surface

Kitchens and tea points

We plan kitchen sealing around when the kitchen is in use. Tell us your site hours and access windows and we’ll plan around them.

Urinals and WC pans

We reseal around urinals and pans with a sanitary grade once the whole of the old bead has gone.

Toilets, showers and kitchens around Walter's Ash

At about 32 miles from central London, Walter's Ash is within reach of the capital, in a commuter belt where offices and business parks are common. Office toilets in the commuter belt are in use from first arrivals to last departures, so we phase work to keep some facilities open.

Church halls and community buildings, such as those at Church of St Botolph, have kitchens and toilets used by many groups, and their sanitary sealant works hard. Student showers at universities like Buckinghamshire New University (Wycombe Campus) (3.6 miles south-east of Walter's Ash) see more use than most, and their silicone shows it. On an industrial estate such as Crownfield Industrial Estate, 1.9 miles to the north-west of Walter's Ash, staff toilets, showers and canteens are where sanitary sealant takes the most wear.

What we can’t put right

Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:

  • Water from plumbing, not from a joint
  • Panel boards already damaged by water
  • Leaks through tanking or membranes below the finishes

If in doubt, give us a call on 01277 525 020 or email a schedule or drawings and we’ll say what we think.

Joints and surfaces we work on

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

Why deal with it now?

Sealing on top of old silicone saves nothing. It doesn’t bond, so it peels and traps dirt behind it. Full removal and proper cleaning is what makes the new joint last. Halls, stores and units around places like Walter's Ash may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Why us?

  • Constructionline member for supplier checks
  • CSCS-carded applicators
  • A range of standard colours, depending on the product
  • Specification-led, product-correct work

After the work

For the best life from the joints:

  • Clear standing water from shower floors where possible
  • Mention any site permits or estates rules at quote stage
  • Keep washrooms out of use until we say the sealant has cured
  • Add sealant joints to planned maintenance checks

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

Small numbers of failed joints are quick to phase in. Left, it tends to become a building-wide job and more closures to manage.
