Washroom sealing for Walton sites

Washroom sealing in Walton, done properly

Black spotting along a sealant bead is not a cleaning problem. The growth is inside the sealant so it returns whatever the cleaning regime. Only replacement gets rid of it for good. Site teams most often ask us about sealant laid over old silicone and now peeling and open joints along basins and vanity units, across urinals and WCs, IPS panels and cubicles and accessible toilets and changing rooms. A specialist sealant contractor works differently from a general builder: in Walton, that means joint design, primers and backing rod as standard.

Rural businesses near smaller places such as Walton, from cafés to event venues, rely on washrooms and kitchens that stay clean. We plan the work around bookings and opening times.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Looking after the joints

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Don’t leave an open joint at a basin or tray
  • Leave signs up until the cure time is over
  • Keep extract fans working and vents clear
  • Inspect washroom sealant regularly

If a joint we sealed fails within 12 months, tell us and we’ll look at it. After that, a routine look catches failing joints early.

Leaks through tray and wet-floor joints can go unseen until a ceiling marks below. By then, other trades may be needed as well so failed joints are worth acting on quickly.

Why deal with it now?

Gaps and mould in joints give dirt and bacteria somewhere to sit, and in kitchens, clinics and schools that is a real concern. A smooth, sealed joint can be cleaned properly. Halls, stores and units around places like Walton may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Why us?

  • Matching to RAL references, product permitting
  • Health and safety: CHAS accredited
  • One contact handling all your sites
  • Colour agreed before work starts

Read our cost guide or how we’re accredited.

Should maintenance staff do it?

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.

For managing agents and facilities managers

For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

What we are called out for in Walton

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

Typical triggers for a call:

  • A new bead over an old one coming away
  • Discoloured joints around urinals and WC pans
  • Users noticing mouldy joints
  • Open joints at the base of cubicle panels

At a university such as University Campus Aylesbury Vale, which lies north-west of Walton, summer is the usual window for resealing residence bathrooms.

Questions to ask before you appoint anyone

Walton: questions and answers

Can you work on a hospital site such as Royal Buckinghamshire Hospital?

Yes. Healthcare sites are among the places we 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 Campus Aylesbury Vale?

Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we will confirm them alongside the quote.

What site paperwork can you supply?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

How many days will you need on site?

The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.

Is colour matching possible?

It depends on the product specified. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.

Are you CHAS accredited?

Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.

Is it possible to just clean mouldy silicone?

Usually not. Mould grows into the sealant itself so cleaning only lightens it for a while. Replacement is the lasting fix.

On site: what to expect

Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. For a building around Walton, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. We agree which washrooms close and when.
  2. Anything behind the joints that needs another trade is flagged.
  3. Old sealant is stripped and the faces prepared.
  4. We reseal with the grade suited to each area.
  5. We confirm reopening times for each washroom.

What we need from you

  • Send asbestos survey details if the building is pre-2000
  • Make sure the joints can be reached
  • Share your working hours and any access restrictions

Advice

Washroom sealing around Walton: points for this area

Walton has a number of hotels close by, all within 2 miles. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time. The work can go floor by floor, agreed with housekeeping. Five care or nursing homes sit less than 2 miles from Walton. In a care setting, a mouldy or lifting joint in a wet room is a hygiene issue as much as a cosmetic one. Each room is kept out of use only as long as the sealant needs.

Toilets at places like Friars Square, less than half a mile to the north-west of Walton, are cleaned constantly, so silicone needs to be sound and smooth. Healthcare estates like Royal Buckinghamshire Hospital (to the north-west of Walton) expect contractors to follow their permits and cleaning rules in every washroom.
