Keeping the joints sound

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

  • Squeegee showers and trays after busy periods
  • Respect the cure time before reopening each room
  • Keep extract fans working and vents clear
  • Act on the first split you see at a shower tray

Ventilation is half the battle. Constant damp lets mould take hold even on anti-mould grades so report fans that aren’t working to your building services team.

Leaks through tray and wet-floor joints can go unseen until a ceiling marks below. At that stage, boards or ceilings may need repair so failed joints are worth acting on quickly.

Washroom sealing in Chieveley

Accessible WCs, showers and changing areas have their own pinch points: shower trays, wet-room floor edges, basins and floor-to-wall junctions. Gaps in those places let water get under the floor or behind panels, so we look at them closely. Most enquiries involve urinal joints that look unhygienic and mould spotting along silicone joints, across vanity units and basins, kitchens and tea points and urinals and WCs. A single leaking joint is often how a building in Chieveley 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.

Community buildings around smaller places like Chieveley have kitchens and toilets used by many people. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Building owners, agents and FMs in Chieveley

Building owners and managing agents use us on everything from one building to a spread of sites around Chieveley. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.

Should maintenance staff do it?

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

How the job changes by surface

IPS and cubicle panels

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

Basins and vanity tops

Stone and some composite tops need a neutral-cure sealant and we choose a neutral-cure grade for them.

What we can’t put right

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Loose panels, vanity units or tiles, which need fixing first
  • Mould caused by poor ventilation, which will return until the extract is fixed

If you’re not sure, just call the office on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.

How a job runs

On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, and the work usually takes between a morning and a week or so, set by the number of rooms and the phasing you need. Rural sites near Chieveley may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. We inspect each washroom and record the joints to be resealed.
  2. You get a fixed quote with the phasing plan.
  3. The whole of the old bead is removed.
  4. Joints are degreased and dried.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Rooms reopen after the cure time.

What we need from you

  • Let us know about inductions and permits
  • Explain the parking and delivery arrangements
  • Move anything stored against the joints

FAQs: Chieveley

Do you take on work at healthcare sites like West Berkshire Community Hospital?

Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.

Is Chieveley off your patch?

Not at all. Chieveley is within our area. London and every South East county are within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Can the sealant be colour-matched?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

Do you have public liability insurance?

Yes. We’re fully insured, and the certificate can go with your quote.

Can you send site paperwork?

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.

Can you clean the mould off instead of resealing?

Cleaning may lighten it, but the mould returns. We replace the sealant with an anti-mould sanitary grade and point out if ventilation is part of the problem.

Does the weather affect the work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
