Washroom sealing near Sibertswold

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

After the work

Keep the joints in good shape with a few simple steps:

  • Clean sealant with gentle products and a soft cloth
  • Don’t leave an open joint at a basin or tray
  • Include joints in routine washroom inspections
  • Clear standing water from shower floors where possible

Mild cleaning products and non-abrasive cloths look after sanitary silicone best. Strong acids, solvents and scourers wear the surface over time.

A split joint at a shower tray can leak for a long time before anyone sees it. At that stage, boards or ceilings may need repair so failed joints are worth acting on quickly.

Washroom sealing in Sibertswold, done properly

When mould has spotted a silicone joint, more cleaning won’t remove it. The growth is inside the sealant, which is why it comes back however often it is treated. Only replacement gets rid of it for good. If you have stained sealant around pans and urinals and sealant laid over old silicone and now peeling, we can help, whatever the surface. Most enquiries from Sibertswold start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

In and around smaller places like Sibertswold, 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.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Work for main contractors and building owners

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

From enquiry to sign-off

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For a building around Sibertswold, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. We agree which rooms close and when, so users always have somewhere to go.
  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. New sanitary silicone with anti-mould additives goes in and is tooled neat.
  6. Rooms reopen after the product’s cure time, and we move to the next.

Preparing the site

  • Agree which areas must stay open
  • Have the specification and drawings to hand
  • Point out parking and an unloading spot

Advice

When to call us in Sibertswold

Low-level joints get hit by mop buckets, cleaning trolleys and feet at skirting lines, urinal bases and around pans.

It’s worth sending us details if you spot any of the following:

  • Users noticing mouldy joints
  • Resealing that didn’t last because the old bead stayed
  • Shower tray joints that have opened up
  • Open joints at the base of cubicle panels

For an occupier at a site such as Pike Road Industrial Estate, which lies north-east of Sibertswold, the canteen and welfare facilities need cleanable joints as much as any office.

Before you book anyone

  • What the guarantee covers, and for how long
  • Can the work be phased to keep areas open?
  • Is the sealant right for the movement and the substrate?
  • Do they follow the manufacturer’s priming guidance?

Our contractor checklist

FAQs: Sibertswold

Do you take on work at healthcare sites like Buckland Hospital?

Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.

Is Sibertswold too far out for you?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Do you do washroom sealing in healthcare settings?

We do. We work to your estates and infection-control requirements and any site permits, and phase the work so areas keep facilities.

What’s the quickest route to a quote?

There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.

How do you choose the sealant?

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.

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.

Is old silicone taken out first?

We always remove it. New silicone won’t stick to the old so a bead over the top fails quickly.

What we can’t put right

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:

  • Panel boards already damaged by water
  • Leaks through tanking or membranes below the finishes
  • A room that stays damp because ventilation isn’t working

If in doubt, ring 01277 525 020 or send details through our quote form and we will say what we think before you book.

What we seal

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

Leave it or put it right?

Leaving the job until a shutdown often means living with it for months. Phasing lets it happen now, with facilities kept in use. One visit to deal with every failing joint makes more sense than several trips to a place like Sibertswold, rather than one at a time. Photos of every joint help us quote for the whole job.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

What you get with us

  • Colour agreed before work starts
  • Constructionline member for supplier checks
  • Work to your specification and the manufacturer’s guidance
  • 12-month guarantee on workmanship
