Washroom sealing for businesses in Tonge Corner

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

What sets the cost

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

  • Quantities, in metres or numbers
  • The product specified
  • How accessible the joints are
  • Phasing around occupants

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

What to include in your enquiry

The more we know, the firmer the quote. Helpful details to send:

  • Whether the building will be occupied during the work
  • Access details, including height
  • Where the site is, with the postcode
  • Any specification or named product

Need a figure for a tender or a budget? We will quote against your scope and drawings you can plan around. If you have questions first, speak to us on 01277 525 020 or email drawings and photos.

Washroom sealing for commercial buildings in Tonge Corner

In a commercial washroom, sealant is usually the first thing to wear out. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day and mould that roots into it can’t be cleaned away. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. We work on IPS panels and cubicles, showers, trays and wet room floors and urinals and WCs, and what we are called in for most is sealant laid over old silicone and now peeling and gaps where vanity tops meet the wall. For commercial sealant work in Tonge Corner, you deal with one contact from quote to sign-off, whether it’s one building or several.

In and around smaller places like Tonge Corner, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Sealant that has gone black with mould usually can’t be cleaned, so it is cut out and replaced.

Our workmanship is guaranteed for 12 months, in Tonge Corner as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Diagnose, treat, sign off

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. If others near Tonge Corner need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  1. First, the phasing is agreed so facilities stay open.
  2. Anything behind the joints that needs another trade is flagged.
  3. Failed sealant and residue are stripped out.
  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

  • Let us know about inductions and permits
  • Point out parking and an unloading spot
  • Make sure the joints can be reached

Common questions from Tonge Corner clients

Will you plan work around the academic year at somewhere like KITE College?

Yes, holiday working periods are the norm on campus jobs. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Is a smaller place like Tonge Corner outside your area?

No. Places such as Tonge Corner are covered as much as the big towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Does the weather affect the work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Will you quote for a small job?

We quote for single jobs as well as large packages and programmes. Send details for a fixed 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.

What guarantee comes with washroom resealing?

Our workmanship has a 12-month guarantee, and we carry public liability insurance.

How long before the toilets can reopen?

Cure times vary by product and temperature. Each room gets its own reopening time from us, and signs stay up until then.

Commercial clients in Tonge Corner

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first.

Doing it in-house

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

How the job changes by surface

Showers and trays

A tray that rocks or has cracked won’t be fixed by sealant, and we’ll say so before resealing.

Changing rooms and gyms

Changing rooms in gyms and leisure centres stay wet and warm, so mould is a constant battle. We use anti-mould sanitary silicone throughout.

Washroom sealing around Tonge Corner: points for this area

The sea is no more than about 2 miles from Tonge Corner, and places by the sea often rely on visitors, so their hotels and holiday lets see heavy seasonal use. Heavy seasonal use is hard on shower and basin sealant, which is why off-season resealing makes sense. There are several hotels within about 2 miles of Tonge Corner. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits.

Pupil toilets at schools like Lansdowne Primary School take heavy daily use, and the holidays give the window to reseal. Halls linked to places like Church of St Giles host groups all week, which is hard on kitchen and toilet sealant. Toilets at colleges like KITE College, 1.2 miles west of Tonge Corner, take heavy use from students and staff alike.

Why act early in Tonge Corner

Water gets behind panels and under floors through a failed joint. In a commercial building that can mean damaged boards, stained ceilings on the floor below and odours, and fixing that takes far more work than resealing. Around Tonge Corner, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.
