Hackney Central: questions and answers

Does a hotel in Hackney Central need to shut while its sealant is renewed?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. The plan is built around your bookings.

Will you plan work around the academic year at somewhere like Queen Mary University of London?

Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

How do you deal with asbestos in old sealant?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

Is it OK to put new silicone on top of the old?

We always remove it. New silicone won’t stick to the old, so sealing over it soon peels.

What site paperwork can you supply?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

Do you do washroom sealing in healthcare settings?

Yes. We work to your estates and infection-control requirements and any site permits. The work is phased around patients or residents.

Which sealant will you use?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Washroom sealing for commercial buildings in Hackney Central

From one staff toilet in Hackney Central to washrooms across a whole estate, we work the same way: details first, then a fixed quote, then the work, then the 12-month guarantee. A few photographs and a count of fittings are enough for a quick quote and a site visit is an option. The enquiries we see most involve washrooms that look worn because of the sealant and failed sealant behind washroom basins, on urinals and WCs, showers, trays and wet room floors and kitchens and tea points. Most enquiries from Hackney Central start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

In Hackney Central, as across London, commercial kitchens and washrooms need sealed joints that can be cleaned properly. Hygienic and anti-mould sanitary sealants are used where they suit, with food-safe products where food contact is possible.

The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What we’re called out for in Hackney Central

A lot of failed washroom sealant was laid over an old bead or a dirty surface. New silicone won’t grip the old, so it soon lets go.

These are often picked up first by site or facilities staff:

  • Failed sealant in a tea point or staff kitchen
  • Open joints at the base of cubicle panels
  • Open joints along basins and vanity units
  • Washrooms that look worn because of the sealant

On an industrial estate such as Bayford Street Industrial Centre (less than half a mile south-east of Hackney Central), staff toilets, showers and canteens are where sanitary sealant takes the most wear.

What your quote should include

  • How joint depth will be controlled
  • How they handle RAMS and site documents
  • Their pre-qualification and accreditations
  • What the guarantee covers, and for how long

Choosing a commercial sealant contractor

Building owners, agents and FMs in Hackney Central

Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules.

What the job involves on each surface

Basins and vanity tops

Basin joints get wet every time someone washes their hands, so the wall joint and bowl surrounds tend to fail before anything else. They are resealed with anti-mould sanitary silicone.

Changing rooms and gyms

Changing rooms can be phased so one stays open. Phasing follows your site hours and access windows.

Cost factors for washrooms and wet areas

Each job is priced on its own details. The main factors are:

  • Working within restricted access windows
  • Which sealant the job calls for
  • Induction, permit and paperwork requirements
  • Location, for remote and island sites

What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote when you’re ready.

What we need to price the job

Whether it’s one area or a whole building, the same details help:

  • Photos of the joints, close up and from further back
  • The site address and postcode
  • The product your specification calls for
  • How the joints are reached, and at what height

The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or ring 01277 525 020 or email a schedule or drawings to discuss it first.

Wet areas in Hackney Central’s workplaces

A 2-mile radius around Hackney Central takes in a good number of hotels. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice. We work a handful of rooms at a time, so the hotel keeps letting the rest. Hackney Central has 13 care or nursing homes no more than 2 miles away. In a care setting, a mouldy or lifting joint in a wet room is a hygiene issue as much as a cosmetic one. We plan the work with the manager so residents are disturbed as little as possible.

En suites at hotels like Kip Hotel (to the north-east of Hackney Central) are cleaned daily, which wears silicone over time. Colleges such as New City College, 1.1 miles to the north of Hackney Central, have toilets, changing rooms and catering kitchens that can be resealed around term dates.
