About our washroom sealing in Middle Stoke

When mould has spotted a silicone joint, more cleaning won’t remove it. The mould has rooted into the silicone itself so it returns whatever the cleaning regime. Only replacement gets rid of it for good. If you have failed joints along IPS and cubicle panels and sealant stained black around basins and showers, we can put it right. Whoever orders the work in Middle Stoke, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Smaller places such as Middle Stoke 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.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

How a job runs

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, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. If others near Middle Stoke need work, visits can be combined. You will have a fixed quote before work starts.

  1. Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
  2. The phasing is agreed so there are always facilities open.
  3. The failed silicone is stripped and every face scraped clean of residue.
  4. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. Rooms reopen after the product’s cure time, and we move to the next.

Advice

What the job involves on each surface

Changing rooms and gyms

Changing rooms can be phased so one stays open. Tell us your site hours and access windows and we will plan around them.

IPS and cubicle panels

Swollen or delaminated boards need replacing and we’ll point out any we see.

Honest limits

Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:

  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Failed tanking beneath a wet-room floor or behind tiles
  • Hollow tiles or loose panels behind the joint

Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we will tell you honestly.

What we seal

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

FAQs: Middle Stoke

Which documents can you supply for work in Middle Stoke?

RAMS, insurance certificate, CSCS details: list what the site needs and we will confirm it with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.

Will all the washrooms in our Middle Stoke building be closed at once?

Normally only some of them, for a short time. We work in phases so other facilities stay open. Each area is handed back once the sealant has cured enough to use.

How do you choose the sealant?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Do you hold CHAS accreditation?

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

Is Middle Stoke in your area?

Yes. Sites across Middle Stoke are covered.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators, as many construction sites ask for.

Does weather matter for sealant work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Maintenance after handover

A few simple habits keep the new joints working:

  • Act on the first split you see at a shower tray
  • Clear standing water from shower floors where possible
  • Keep a record of which washrooms need attention
  • Keep washrooms out of use until we say the sealant has cured

If a joint we sealed fails within 12 months, tell us and we will look at it. Beyond that, regular checks keep small problems small.

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.

How the quote is worked out

We price every job individually. The main factors are:

  • Quantities, in metres or numbers
  • Any access equipment needed
  • Site requirements such as inductions and permits
  • How much existing material needs removing

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we’ll explain how it’s made up.

Sending details for a quote

For an accurate fixed quote, we need to understand the site. Send us:

  • Asbestos survey details if the building is older
  • Rough lengths or quantities, or drawings if you have them
  • What the building is and how it’s used
  • When you need the work done

Pricing a project or setting a maintenance budget? We will quote against your scope and drawings you can plan around. If you have questions first, call the office on 01277 525 020 or email a schedule or drawings.

Common problems we fix in Middle Stoke

Commercial cleaning is harder on sealant than everyday use. Strong chemicals, scourers and jet washing roughen, discolour or lift a bead so grime sticks to the damaged surface.

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

  • Complaints from staff, guests or users about tired washrooms
  • Gaps where vanity tops meet the wall
  • Black mould inside silicone joints that cleaning can’t shift
  • Discoloured joints around urinals and WC pans

Where you are responsible for a hall attached to a building such as Church of St Peter and St Paul, its kitchen and toilets need sealant that stays cleanable.

Questions to ask before you book

  • Are they CHAS accredited or on Constructionline?
  • How they handle RAMS and site documents
  • How the existing material will be dealt with
  • Can the work be phased to keep areas open?
