About our washroom sealing in Wittensford

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. Every resealed washroom carries our 12-month guarantee. If you have stained sealant around pans and urinals and split or peeling sealant at shower trays, we can put it right. A specialist sealant contractor works differently from a general builder: in Wittensford, that means joint design, primers and backing rod as standard.

Smaller places such as Wittensford still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

On site: what to expect

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes a morning or so for a small washroom, longer where showers and changing rooms are included, and our waste is bagged and taken away as we go. For work around Wittensford, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
  2. We agree which rooms close and when, so users always have somewhere to go.
  3. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. Joints are cleaned, degreased and dried before sealing.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. Each room is handed back once the sealant has had its cure time.

What we need from you

  • Share the asbestos register for older buildings
  • Point out any areas we must not close
  • Send your site hours and access windows

Advice

Questions about Wittensford

Would you work within a site like Tatchbury Mount Hospital?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

Does a hotel in Wittensford need to shut while its sealant is renewed?

Rarely, if ever. We take a few rooms out at a time. We agree the order of rooms and the timings with you before we start.

What if there’s asbestos in the old mastic?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

Will you quote for a small job?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

Which sealant will you use?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

Is it possible to just clean mouldy silicone?

Surface cleaning won’t reach mould that has rooted into the bead. New anti-mould sanitary silicone is the treatment and check the ventilation isn’t the cause.

Wet areas in Wittensford’s workplaces

There are several hotels within about 2 miles of Wittensford. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. The work can go floor by floor, agreed with housekeeping.

On an industrial estate such as Mortimer Trading Estate (3 miles north-east of Wittensford), staff toilets, showers and canteens are where sanitary sealant takes the most wear. For a hotel such as The Bartley Lodge Hotel (1 mile south-east of Wittensford), resealing en suites a few rooms at a time keeps the rest available. Staff changing rooms and patient toilets at places like Tatchbury Mount Hospital (to the east of Wittensford) need cleanable, sound silicone.

What we can’t put right

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • A room that stays damp because ventilation isn’t working
  • Leaks through tanking or membranes below the finishes
  • Fittings that move too much to hold a bead

If in doubt, ring 01277 525 020 or email drawings and photos and we’ll say what we think.

Surfaces we seal

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

Cost factors for washrooms and wet areas

What shapes the price:

  • The size and state of each joint
  • How much there is to seal
  • Access and working height
  • The site’s rules and procedures

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Sending details for a quote

A good diagnosis starts with the right details. Let us know:

  • The site address and postcode
  • Any dates the work must fit around
  • Whether the building will be occupied during the work
  • Approximate linear metres or a joint schedule

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call 01277 525 020 or send details through our quote form.

Maintenance after handover

Problems stay small when the joints are checked regularly. In particular:

  • Include joints in routine washroom inspections
  • Brief cleaning staff to treat joints gently
  • Clear standing water from shower floors where possible
  • Act on the first split you see at a shower tray

Add washroom sealant to routine inspections. Check for mould spots, splits, lifting edges and open joints at trays, basins and urinals and log what you find.

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.

Building owners, agents and FMs in Wittensford

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

What happens if it’s left?

Open or mouldy joints are hard to keep hygienic which matters most in healthcare, food and education settings. A smooth, sealed joint can be cleaned properly. One visit to deal with every failing joint makes more sense than several trips to a place like Wittensford. Photos of every joint help us quote for the whole job.

A quote for washrooms and wet areas depends on quantities, condition and access, and any specification that applies. Call for a quote.

Why us?

  • Health and safety: CHAS accredited
  • Joints cleaned back to sound surfaces
  • Colours chosen to suit frames, cladding or finishes where possible
  • Colour agreed before work starts
