Washroom sealing for businesses in Ashurst

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Aftercare for building managers

Problems stay small when the joints are checked regularly. Specifically:

  • Add sealant joints to planned maintenance checks
  • Brief cleaning staff to treat joints gently
  • Don’t leave trays and floors sitting wet
  • Keep a record of which washrooms need attention

Any failure in our workmanship within the 12-month guarantee is ours to put right. After that, a routine look catches failing joints early.

Mouldy sealant only gets harder to ignore and users notice. Dealing with it while it’s just the sealant keeps it simple.

Washroom sealing in Ashurst

In a commercial washroom, sealant is normally the first thing to wear out. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning, and once mould grows into it, it can’t be scrubbed out. We strip it out and lay new anti-mould sanitary silicone. Most enquiries involve a new bead over an old one coming away and gaps where vanity tops meet the wall, on vanity units and basins, IPS panels and cubicles and showers, trays and wet room floors. A single leaking joint is often how a building in Ashurst first comes to us: 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 Ashurst, 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.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, speak to us on 01277 525 020 or send photos by email and we will come back to it.

Common questions from Ashurst clients

Would you work within a site like Tunbridge Wells Homeopathic Hospital?

Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.

Is Ashurst off your patch?

No. Places such as Ashurst are covered as much as the big towns. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Are you CHAS accredited and on Constructionline?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

Is it OK to put new silicone on top of the old?

The whole of the old bead is removed and the surfaces cleaned first. It’s the difference between a joint that lasts and one that peels.

What if there’s asbestos in the old mastic?

The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

What guarantee comes with washroom resealing?

There is a 12-month guarantee on our workmanship, and we carry public liability insurance.

What affects the price in Ashurst

A fixed quote reflects the actual work. It takes account of:

  • Induction, permit and paperwork requirements
  • The total length or number of joints
  • Any access equipment needed
  • The size and state of each joint

The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Sending details for a quote

Good information means a firmer quote. Helpful details to send:

  • Where the site is, with the postcode
  • The asbestos register, for older buildings
  • Drawings or a marked-up plan, if available
  • How the joints are reached, and at what height

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.

On site: what to expect

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Smaller jobs around Ashurst can be grouped with others nearby. You will have a fixed quote before work starts.

  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. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  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

  • Send your site hours and access windows
  • Point out any areas we must not close
  • Tell staff and tenants when we’ll be in

Different surfaces, different methods

Basins and vanity tops

Water getting past a vanity top joint can swell the board beneath. Resealing early protects the unit.

IPS and cubicle panels

IPS panels and cubicle systems have joints at the wall, the floor and the worktop. They stop water reaching the panel boards.

Washroom sealing around Ashurst: how the place shapes the job

Central London is about 28 miles from Ashurst. Business park offices have washrooms in daily use by staff, which is why the work is phased.

On a healthcare site such as Tunbridge Wells Homeopathic Hospital, 4.4 miles to the east of Ashurst, washroom work starts with the infection-control team’s sign-off. Office washrooms on sites such as Speldhurst Business Park, 2.8 miles to the east of Ashurst, are in use all working day, so resealing is phased to keep some open. At a university such as Canterbury Christ Church University - Salomons, 4 miles north-east of Ashurst, summer is the usual window for resealing residence bathrooms.

General trades versus a specialist

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
