Washroom sealing for commercial buildings in Newington Butts

Washroom joints need the right sealant, not whatever is to hand. Sanitary silicone contains additives that resist mould, and neutral-cure types are used where acetoxy silicone could attack some metals, stone or mirror backings. In food areas, hygienic or food-safe sealants are used where food contact is possible. We work on vanity units and basins, showers, trays and wet room floors and urinals and WCs, and the failures we’re asked to look at most are sealant lifting along a tray edge and a new bead over an old one coming away. Whoever orders the work in Newington Butts, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

Building managers in Newington Butts typically 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.

We stand by our work with a 12-month guarantee. That covers our preparation and application.

What happens if it’s left?

Open or mouldy joints are hard to keep hygienic, and in kitchens, clinics and schools that is a real concern. Sound, smooth joints are much easier to keep clean. Getting scaffold, permits or access booked in Newington Butts takes effort, so it makes sense to deal with every failing joint while access is in place.

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.

Why us?

  • Standard and matched colours in many product ranges
  • Clear, fixed quotes
  • Products installed to the manufacturer’s instructions
  • Our applicators hold CSCS cards

See our cost guide and our accreditations and insurance.

How a job runs

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. All of Greater London is in the ULEZ, and kerbside space in Newington Butts can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.

  1. We agree which washrooms close and when.
  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.

Getting the site ready

  • For older buildings, check the asbestos register before work
  • Arrange parking or a loading space
  • Make sure the joints can be reached

Request a quote

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.

How the quote is worked out

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

  • Backing rod, priming and other preparation
  • Site requirements such as inductions and permits
  • How much existing material needs removing
  • How accessible the joints are

Pricing washrooms and wet areas depends on quantities, condition and access. Ask us for a fixed quote.

Before you send an enquiry

We can often quote from photos and a few details. Please tell us:

  • Specification clauses that apply
  • A wide shot and a close-up of the area
  • The asbestos register, for older buildings
  • Whether the building will be occupied during the work

Questions about Newington Butts

Is a hospital such as Evelina London Children's Hospital somewhere you can work?

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Must a hotel around Newington Butts 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’ll plan around them.

Will you come and look before quoting?

Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.

What sealant do you use in washrooms?

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

Do you offer coloured sealant?

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

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

How do we ask for a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.

Should maintenance staff do it?

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

What the job involves on each surface

Showers and trays

Shower joints in hotels, gyms and workplaces work hard. Every joint is stripped, degreased, dried and given a new bead.

Urinals and WC pans

Joints around urinals and WC pans take splashes, cleaning chemicals and knocks. Once they discolour or split, they hold odours and make the room look neglected.
