Washroom sealing near The Burroughs

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

When it isn’t the sealant

We check first that sealant really is the fix. It isn’t the answer for:

  • Condensation from failed extract fans
  • Leaks through tanking or membranes below the finishes
  • Loose panels, vanity units or tiles, which need fixing first

If in doubt, call 01277 525 020 or use the quote form and we’ll say what we think.

What we seal

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

Washroom sealing in The Burroughs

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. There is public liability insurance behind every job. Every resealed washroom carries our 12-month guarantee. Most enquiries involve panel joints letting water behind and failed sealant in a tea point or staff kitchen, on accessible toilets and changing rooms, vanity units and basins and kitchens and tea points. Facilities teams, main contractors and managing agents in The Burroughs tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Building managers in The Burroughs usually need some facilities open throughout. Washrooms are done core by core or floor by floor, with signage and a plan agreed beforehand.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Sanitary sealant for The Burroughs buildings

A London building with hundreds of occupants can’t lose every washroom for a day, which is why the work is split into phases agreed in advance. The area within 2 miles of The Burroughs holds plenty of hotels. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. Rooms are done in turn so most stay available.

Healthcare washrooms on sites such as BMI Hendon Hospital (to the north-east of The Burroughs) are resealed area by area, under the site’s own infection-control rules. Colleges such as College of North West London, 2.6 miles to the south of The Burroughs, have toilets, changing rooms and catering kitchens that can be resealed around term dates. At a university such as Middlesex University, which lies north-west of The Burroughs, summer is the usual window for resealing residence bathrooms.

On site: what to expect

At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. For a job in The Burroughs, access comes first. Give us the hours we can be on site and we’ll schedule to suit.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. A phasing plan keeps part of the building’s facilities in use at all times.
  3. The failed silicone is stripped and every face scraped clean of residue.
  4. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  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

  • Agree which areas must stay open
  • Tell us what induction or permit system the site runs
  • Move anything stored against the joints

What sets the cost

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

  • Any access equipment needed
  • Travel to remote or island sites
  • How much existing material needs removing
  • Site requirements such as inductions and permits

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

Details that help us quote

It doesn’t need to be a full survey. A few details are enough to get going:

  • Approximate linear metres or a joint schedule
  • How the joints are reached, and at what height
  • The type of building and who uses it
  • When you need the work done

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

What happens if it’s left?

Waiting for a holiday closure can leave failing joints in place for a long time. With phasing, the work can go ahead while most facilities stay open. Failed sealant in a building in The Burroughs can quickly affect neighbours, tenants or the floor below. Dealing with it early is simpler for everyone.

No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Different surfaces, different methods

Urinals and WC pans

Floor joints around WC pans are often forgotten. We include them in the survey.

IPS and cubicle panels

Swollen or delaminated boards need replacing, and any we come across will be pointed out.

For managing agents and facilities managers

If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. The Burroughs can form part of a wider programme.

Questions we are asked in The Burroughs

Will you plan work around the academic year at somewhere like Middlesex University?

Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Can you cope with the access rules in a London building?

Yes. Inductions, permits and timed loading are routine for us in London. Say when the building is occupied and when it’s quiet, and we will plan accordingly. The ULEZ covers the whole of Greater London, which we allow for

Do you use special sealant for toilets and showers?

It depends on the joint. Most washroom joints take sanitary silicone while kitchens may need a food-safe grade.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and we will price the work to it, flagging anything that needs clarifying.

Does weather matter for sealant work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Can you reseal washrooms in healthcare buildings?

We work in clinics, hospitals and care homes. Any records you need are confirmed with the quote before we start.

Can washrooms stay open while you work?

Just the room being resealed is out of use. Rooms go back into use once the sealant has cured, then we move on.
