Washroom sealing in Chase Cross

Since 2005 we have resealed commercial washrooms for facilities teams, contractors and building owners. We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. We are fully insured. Every resealed washroom carries our 12-month guarantee. Site teams most often ask us about failed joints along IPS and cubicle panels and washrooms that look worn because of the sealant, across showers, trays and wet room floors, vanity units and basins and kitchens and tea points. Looking for mastic applicators who cover Chase Cross? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Building managers in Chase Cross usually need some facilities open throughout. We work through washrooms floor by floor or core by core, at times agreed with you, so staff and visitors can always find an open washroom.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What the job involves on each surface

Healthcare and care settings

Healthcare work is phased so wards, clinics or residents’ areas keep their facilities. Tell us what records you need and we’ll confirm with the quote.

Showers and trays

If a tray moves too much or is cracked, it needs attention first, and we’ll say so before resealing.

On site: what to expect

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.

  1. We survey each room, count the joints and note anything behind them that needs another 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. Joints are cleaned, degreased and dried before sealing.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. Rooms reopen after the product’s cure time, and we move to the next.

Preparing the site

  • For older buildings, check the asbestos register before work
  • Share your working hours and any access restrictions
  • Confirm the product named in the specification

Getting a fixed quote

Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. The easiest way is to ring 01277 525 020 or send photos by email.

Related advice

Chase Cross: questions and answers

Would you work within a site like Victoria Hospital?

Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.

Must a hotel around Chase Cross close while you work?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. Tell us your quiet periods and access windows and we will plan around them.

Do you cover Chase Cross?

Yes. Sites across Chase Cross are covered, with one number for every area we cover.

When can showers be used after new sealant?

Cure times vary by product and temperature. You’ll get a reopening time for each area, and signs stay up until then.

Can washrooms stay open while you work?

Only the area we’re working in is closed. Rooms go back into use once the sealant has cured, then we move on.

Can you send site paperwork?

Each site asks for different documents, so tell us what you need and we will confirm it when we quote.

Is colour matching possible?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.

What we can’t put right

Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:

  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Condensation from failed extract fans
  • Panel boards already damaged by water

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

Joints and surfaces we work on

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

Building owners, agents and FMs in Chase Cross

When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Toilets, showers and kitchens around Chase Cross

There are a number of hotels within about 2 miles of Chase Cross. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. London offices and hotels normally can’t close all their washrooms at once, so we take one block of facilities out of use at a time.

For a hall at a building such as St James, resealing the kitchen and toilets can be fitted between bookings. Customer toilets in retail centres such as Romford Shopping Hall (1.8 miles south of Chase Cross) rarely close, so resealing is phased. Staff changing rooms and patient toilets at places like Victoria Hospital, 1.6 miles to the south of Chase Cross, need cleanable, sound silicone.

Chase Cross is about 2 miles north of Romford, in Greater London. We cover commercial sites throughout Chase Cross, for single jobs and planned programmes alike. Across Greater London, 764 places are covered, Chase Cross among them. Sites around London have their own page, roughly 14 miles from Chase Cross.

Anyone looking for washroom sealing in RM5, RM1 and RM4 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee.

If your building is just outside Chase Cross, we cover Havering-atte-Bower (1 mile north-east), Redbridge (2 miles west), Stapleford Abbotts (2 miles north), Lambourne End (3 miles north-west) and Chigwell Row (3 miles west).

Why it’s worth doing now in Chase Cross

Leaving the job until a shutdown often means living with it for months. Phasing lets it happen now, with facilities kept in use. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.

We don’t publish prices, since every building and every scope is different. Call for a quote.
