About our washroom sealing in Waterford

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. The enquiries we see most involve kitchen worktop joints that can’t be kept clean and open joints at the base of cubicle panels, across vanity units and basins, kitchens and tea points and urinals and WCs. Whether you call it commercial sealant work, mastic application or joint sealing, in Waterford it comes down to the same thing: the right product in a properly prepared joint.

Community buildings around smaller places like Waterford have kitchens and toilets used by many people. Resealing sinks, worktops and WCs with anti-mould silicone keeps them clean and watertight.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

Doing it in-house

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

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.

Leave it or put it right?

Water gets behind panels and under floors through a failed joint. That can lead to swollen boards, marked ceilings below and lingering smells which costs more to fix than a reseal. Halls, stores and units around places like Waterford may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.

What the job involves on each surface

Urinals and WC pans

We reseal around urinals and pans with a sanitary grade after the old bead and residue are removed.

Basins and vanity tops

Water getting past a vanity top joint can swell the board beneath. Prompt resealing keeps the unit sound.

Our process

At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. Smaller jobs around Waterford can be grouped with others nearby. A fixed quote is given before anything starts.

  1. First, the phasing is agreed so facilities stay open.
  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.

Before we start on site

  • Agree which areas must stay open
  • Clear stock, furniture or equipment away from the joints
  • Share the asbestos register for older buildings

Getting a fixed quote

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.

Advice

Wet areas in Waterford’s workplaces

The area within 2 miles of Waterford holds a number of hotels. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice. The work can go floor by floor, agreed with housekeeping. Waterford lies roughly 22 miles out from central London, within the office belt around the capital. Business park offices have washrooms in daily use by staff, which is why the work is phased.

For a college such as Hertford College: Ware Campus, 2.9 miles east of Waterford, half-term and summer give the windows for washroom work. Halls linked to places like Church of St Michael and All Angels host groups all week, which is hard on kitchen and toilet sealant. In a centre such as Madford Retail Park (1.8 miles south-east of Waterford), public washrooms are resealed a block of facilities at a time.

Waterford is about 1 mile north-west of Hertford, in Hertfordshire. Commercial clients in Waterford can call on us for washrooms and wet areas. Across Hertfordshire, 371 places are covered, Waterford among them. There’s a separate page for London, roughly 22 miles from Waterford.

What we can’t put right

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • A room that stays damp because ventilation isn’t working
  • Failed tanking beneath a wet-room floor or behind tiles
  • Panel boards already damaged by water

Not sure which it is? You can call 01277 525 020 or send details through our quote form and we will tell you honestly before you book.

Surfaces we seal

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

Common questions from Waterford clients

Is Waterford too far out for you?

No. Places such as Waterford are covered as much as the big towns. We work across Greater London and the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Do you take on work at healthcare sites like Hertford County Hospital?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

When can showers be used after new sealant?

That varies with the sealant and the room temperature. You will get a reopening time for each area before we leave it.

How much does the work cost?

Each job is quoted on its own details. To get one, give us a call on 01277 525 020 or email drawings and photos.

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, let us know and we will send them with the quote.

What’s the quickest route to a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.

What sealant do you use in washrooms?

Sanitary silicone with anti-mould additives for most washroom joints. Neutral-cure grades are used where acetoxy types could mark metals, stone or mirror backings.

Looking after the joints

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

  • Keep a record of which washrooms need attention
  • Avoid scourers and harsh descalers on silicone
  • Act on the first split you see at a shower tray
  • Report faulty extraction promptly

We hand each area back once the silicone has had the cure time the product needs. You’ll be told when showers and basins can be used again, and it helps if signs stay up until then.

A split joint at a shower tray can leak for a long time before anyone sees it. At that stage, boards or ceilings may need repair, so reseal when you first spot a split.
