Washroom sealing for West Itchenor sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

After the work

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

  • Brief cleaning staff to treat joints gently
  • Keep washrooms out of use until we say the sealant has cured
  • Tell us about infection-control or permit rules before we quote
  • Keep extract fans working and vents clear

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.

Mouldy sealant only gets harder to ignore, and complaints follow. Dealing with it while it’s just the sealant keeps it simple.

Washroom sealing for commercial buildings in West Itchenor

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. We work on accessible toilets and changing rooms, IPS panels and cubicles and vanity units and basins, and the usual reasons a site gets in touch are sealant stained black around basins and showers and kitchen worktop joints that can’t be kept clean. Searching for sealant specialists in West Itchenor? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

Smaller places such as West Itchenor 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.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Diagnose, treat, sign off

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. If others near West Itchenor need work, visits can be combined. You’ll 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. We clean and dry every surface so the new sealant can grip.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. Each room is handed back once the sealant has had its cure time.

Preparing the site

  • Confirm the product named in the specification
  • Point out parking and an unloading spot
  • For older buildings, check the asbestos register before work

When to bring in a specialist

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

What sets the cost

Your fixed quote is built from the real scope. It allows for:

  • Travel to remote or island sites
  • The total length or number of joints
  • Working within restricted access windows
  • Site requirements such as inductions and permits

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

What we need to price the job

Diagnosis starts before we arrive. Let us know:

  • Asbestos survey details if the building is older
  • The type of building and who uses it
  • Photos of the joints, close up and from further back
  • Rough lengths or quantities, or drawings if you have them

The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or call the office on 01277 525 020 or email a schedule or drawings to discuss it first.

What sealant work can’t fix

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Swollen or delaminated boards behind panels or vanity tops
  • Water escaping beneath the floor rather than through a joint
  • Leaking pipes, traps, wastes or cisterns, which need a plumber

Not sure which it is? You can ring 01277 525 020 or email the details over and we will tell you honestly.

Where we work in West Itchenor

West Itchenor: questions and answers

Is West Itchenor too small for you to travel to?

Not at all. West Itchenor is within our area. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Can you take on a job at a hospital such as St Richard's Hospital?

Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.

Do you use special sealant for toilets and showers?

An anti-mould sanitary silicone in the majority of cases. Neutral-cure grades are used where acetoxy types could mark metals, stone or mirror backings.

When can showers be used after new sealant?

Each sealant has a cure time before it should get wet. We plan the phasing around that so there are always rooms open.

Will all the toilets be closed at once?

We phase it so users always have somewhere to go. We work through the building a room or section at a time around your site hours and access windows.

How much does the work cost?

That depends on the job: quantities, access, the product and any phasing. Call for a fixed quote.

Is colour matching possible?

It depends on the product specified. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.

Work for main contractors and building owners

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.

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules.

Wet areas in West Itchenor’s workplaces

West Itchenor sits close to the coast, within about 1 mile, and coastal places often have hotels, guest houses and holiday accommodation with busy seasons. Washrooms used guest after guest wear their sanitary silicone faster, so resealing in the quieter months keeps rooms ready. West Itchenor is about 59 miles from central London. Office toilets in the commuter belt are in use from first arrivals to last departures, so we phase work to keep some facilities open.

For a site such as St Richard's Hospital (5 miles north-east of West Itchenor), sanitary joints in clinical areas need sound, cleanable sealant and a careful method. Where you’re responsible for a hall attached to a building such as St Nicholas' Church, its kitchen and toilets need sealant that stays cleanable. For an occupier at a site such as Southfield Industrial Park., 2.5 miles north of West Itchenor, the canteen and welfare facilities need cleanable joints as much as any office.
