Common questions from Swerford clients

What paperwork can you provide for a job in Swerford?

We will confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.

Is Swerford off your patch?

Not at all. Swerford is within our area. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

How soon can a washroom be used after resealing?

Each sealant has a cure time before it should get wet. Phasing is planned with the cure time in mind so there are always rooms open.

Is it possible to just clean mouldy silicone?

Surface cleaning won’t reach mould that has rooted into the bead. We replace the sealant with an anti-mould sanitary grade and check the ventilation isn’t the cause.

Does weather matter for sealant work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

Do you work to architects’ specifications?

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

How do we ask for a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.

Washroom sealing in Swerford

In a busy washroom, the sealant usually gives up long before the tiles or fittings. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning and mould that roots into it can’t be cleaned away. We strip it out and lay new anti-mould sanitary silicone. Site teams most often ask us about open joints along basins and vanity units and failed joints along IPS and cubicle panels, on urinals and WCs, IPS panels and cubicles and kitchens and tea points. Looking for mastic applicators who cover Swerford? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

In and around smaller places like Swerford, 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: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Diagnose, treat, sign off

Before we leave any area, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. Rural sites near Swerford may need directions, gate codes or a contact on site. Send that with the details and we’ll 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 give you a reopening time for every room.

What we need from you

Washroom sealing in Swerford: the local picture

Central London is about 67 miles from Swerford, in a commuter belt where offices and business parks are common. Office washrooms on business parks see heavy weekday use, so we phase work to keep some facilities open.

Washrooms near Swerford get the old silicone stripped out and a fresh anti-mould bead on dry joints. Where you’re responsible for a hall attached to a building such as Church of St Mary, its kitchen and toilets need sealant that stays cleanable.

Swerford is about 7 miles south-west of Banbury, in Oxfordshire. Our applicators travel to Swerford for work on washrooms and wet areas. Swerford is one of 423 places in Oxfordshire on our list. For work in that direction, see our Oxford page, about 18 miles away.

After the work

Once the work is signed off, a little attention goes a long way:

  • Don’t leave an open joint at a basin or tray
  • Add sealant joints to planned maintenance checks
  • Squeegee showers and trays after busy periods
  • Leave signs up until the cure time is over

Each room goes back into use only when the sealant has cured enough. We’ll tell you when the wet areas can be used, and it helps if signs stay up until then.

Water getting behind IPS panels and vanity units can swell the boards. After that, those parts need replacing rather than resealing.

How the job changes by surface

Healthcare and care settings

Clinics, hospitals and care homes need joints that can be kept clean. Your infection-control and estates rules are followed as well as site permits.

IPS and cubicle panels

Panel systems meet walls, floors and vanity tops at sealed joints. Those joints protect the boards behind from water.

Why it’s worth doing now in Swerford

Cleaning mouldy sealant only masks it but the growth is inside the bead and returns. Replacement deals with the cause in the joint and cleaners stop fighting a losing battle. Halls, stores and units around places like Swerford may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

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

What sealant work can’t fix

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Vanity carcasses that have swollen
  • Loose panels, vanity units or tiles, which need fixing first
  • A dripping waste or valve behind a panel

If you’re not sure, just give us a call on 01277 525 020 or use the quote form and we will give you a straight answer.
