Washroom sealing near Hatford

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

How we handle washroom sealing in Hatford

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. Site teams most often ask us about open joints along basins and vanity units and shower tray joints that have opened up, across vanity units and basins, urinals and WCs and IPS panels and cubicles. Looking for mastic applicators who cover Hatford? We’ve been sealing commercial buildings since 2005.

In and around smaller places like Hatford, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Sealant that has gone black with mould normally can’t be cleaned, so it is cut out and replaced.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Your questions answered

Would you work within a site like Longworth Hospital?

Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Will you plan work around the academic year at somewhere like University of Oxford?

Yes, holiday working periods are the norm on campus jobs. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

What happens if old sealant might contain asbestos?

The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

How long does a job like this take?

It depends on the scope, but the work usually takes a few hours for one toilet block, with bigger buildings phased across a number of visits. For bigger or phased jobs, we will set out a timescale with the quote.

Are you fully insured?

Yes. We’re fully insured, including public liability cover.

How do I request a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.

Does the weather affect the 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.

When it isn’t the sealant

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Failed tanking beneath a wet-room floor or behind tiles
  • Hollow tiles or loose panels behind the joint
  • Vanity carcasses that have swollen

If you’re not sure, just call the office on 01277 525 020 or email drawings and photos and we will give you a straight answer.

Joints and surfaces we work on

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

How the job changes by surface

Kitchens and tea points

In commercial kitchens, smooth, cleanable joints help keep the kitchen hygienic. Where food contact is possible, we use a hygienic, food-safe sealant.

Basins and vanity tops

Water getting past a vanity top joint can swell the board beneath. Resealing early protects the unit.

From enquiry to sign-off

Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Smaller jobs around Hatford can be grouped with others nearby. You will have a fixed quote before work starts.

  1. Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
  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. 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

  • Tell us what induction or permit system the site runs
  • Tell us which areas need to stay in use
  • Let building users know which areas are affected

Quotes

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Work for main contractors and building owners

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, which keeps the paperwork simple.

Doing it in-house

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

What we are called out for in Hatford

Low-level joints get hit by mop buckets, cleaning trolleys and feet, especially at floor edges and around urinals and WC pans.

Look out for the following:

  • Mould spotting along silicone joints
  • Panel joints letting water behind
  • Washrooms that look worn because of the sealant
  • Split or peeling sealant at shower trays

At a hospital like Longworth Hospital (3.1 miles west of Hatford), patient and staff washrooms are best done in short phases agreed with the ward.

Before you book anyone

  • Whether their applicators hold CSCS cards
  • Can the work be phased to keep areas open?
  • What level of public liability insurance do they hold?
  • Is the sealant right for the movement and the substrate?
