Washroom sealing across Hattingley

Your questions answered

Is a hospital such as Alton Community Hospital somewhere you can work?

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

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

Not all at once. We take one block of facilities at a time. We will tell you the curing time for the product before we start.

Can you handle several sites?

Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.

How do you choose the sealant?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

What guarantee comes with washroom resealing?

Every job carries our 12-month guarantee. It covers our workmanship rather than damage, leaks from plumbing or ventilation problems.

Can you work to our specification?

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

Can weather delay the job?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Washroom sealing for commercial buildings in Hattingley

Since 2005 we have resealed commercial washrooms for facilities teams, contractors and building owners. We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. We are fully insured. Our workmanship is guaranteed for 12 months. We work on IPS panels and cubicles, vanity units and basins and showers, trays and wet room floors, and what we are called in for most is users noticing mouldy joints and sealant lifting along a tray edge. Whoever orders the work in Hattingley, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

Halls and community buildings near places like Hattingley 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: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Leave it or put it right?

Running fresh silicone along a failed bead hides the problem briefly. It doesn’t bond, so it peels and traps dirt behind it. Cutting out completely and cleaning back takes a little longer and lasts. For buildings around smaller places like Hattingley, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Our process

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. If others near Hattingley need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  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

  • Agree which areas must stay open
  • Send your site hours and access windows
  • Explain the parking and delivery arrangements

Getting a fixed quote

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, phone 01277 525 020 or send photos by email.

Different surfaces, different methods

Urinals and WC pans

Joints around urinals and WC pans take splashes, cleaning chemicals and knocks. Stained or split joints here trap smells and look unhygienic.

Wet-room floors and floor-to-wall joints

Changing rooms and accessible showers often have wet floors so the edges are checked carefully.

Should maintenance staff do it?

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.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

After the work

A few simple habits keep the new joints working:

  • Keep washrooms out of use until we say the sealant has cured
  • Act on the first split you see at a shower tray
  • Tell us about infection-control or permit rules before we quote
  • Keep a record of which washrooms need attention

Squeegeeing showers and trays after heavy use helps. Joints that sit wet for hours fail sooner.

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.

What we’re called out for in Hattingley

Mop buckets, trolleys and knocks from users damage joints near the floor at skirting lines, urinal bases and around pans.

Any of the following is a good reason to get the joints checked over:

  • Users noticing mouldy joints
  • Shower tray joints that have opened up
  • Black mould inside silicone joints that cleaning can’t shift
  • A new bead over an old one coming away

On an industrial estate such as Barton Industrial Estate (1 mile north-west of Hattingley), staff toilets, showers and canteens are where sanitary sealant takes the most wear.

Questions to ask before you book

  • Will RAMS and insurance details be available?
  • How the joint faces will be prepared and primed
  • Will CSCS-carded applicators be on site?
  • Their pre-qualification and accreditations

At about 50 miles from central London, Hattingley is within reach of the capital. Washrooms in commuter-belt offices take constant weekday traffic, which is why the work is phased.

For a hall at a building such as Church of St Andrew, resealing the kitchen and toilets can be fitted between bookings. For a school such as Medstead Church of England Primary School, washroom and kitchen sealant can be renewed around term dates.
