Questions we are asked in South Tottenham

Could you schedule work at a campus like University of Portsmouth Walthamstow Campus for the vacation?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Is hospital work, at somewhere like St Ann's Hospital, something you do?

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

Is South Tottenham in your area?

Yes. South Tottenham is in our area and the rest of Greater London, within our coverage of Greater London, South East England and Scotland. For a quote, speak to us on 01277 525 020 or send details through our quote form.

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

What’s the quickest route to a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.

Will your applicators have CSCS cards?

Yes. Our applicators hold CSCS cards, as many construction sites ask for.

Can you quote from photos?

Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit before quoting.

How we handle washroom sealing in South Tottenham

From one staff toilet in South Tottenham to washrooms across a whole estate, the route is the same: details first, then a fixed quote, then the work, then the 12-month guarantee. Photos and a rough count of basins, urinals, showers and cubicles help us give a quick quote, or we can arrange a visit. The enquiries we see most involve stained sealant around pans and urinals and a new bead over an old one coming away, on showers, trays and wet room floors, vanity units and basins and kitchens and tea points. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in South Tottenham, preparation and product choice get the time they need.

In South Tottenham, 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.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

How a job runs

Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.

  1. We inspect each washroom and record the joints to be resealed.
  2. You get a fixed quote with the phasing plan.
  3. The whole of the old bead is removed.
  4. Each joint is cleaned and left dry.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Each area is handed back when ready.

Before we start on site

  • Share the asbestos register for older buildings
  • Send your site hours and access windows
  • Tell us what induction or permit system the site runs

Advice

Commercial clients in South Tottenham

Building owners and managing agents use us on everything from one building to a spread of sites around South Tottenham. One quote can cover more than one site, which keeps the paperwork simple.

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

Keeping the joints sound

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Add sealant joints to planned maintenance checks
  • Clear standing water from shower floors where possible
  • Keep a record of which washrooms need attention
  • Keep extract fans working and vents clear

If a joint we sealed fails within 12 months, tell us and we’ll look at it. After that, a routine look catches failing joints early.

Leaks through tray and wet-floor joints can go unseen until a ceiling marks below. At that stage, boards or ceilings may need repair so failed joints are worth acting on quickly.

Common problems we fix in South Tottenham

Warmth, moisture and soap residue are exactly what mould needs, and sealant joints trap all three. Anti-mould additives help, but in a poorly ventilated room mould can still take hold eventually.

Common reasons buildings call us in:

  • Sealant lifting along a tray edge
  • Sealant laid over old silicone and now peeling
  • Stained sealant around pans and urinals
  • Users noticing mouldy joints

At a university such as University of Portsmouth Walthamstow Campus (2.4 miles east of South Tottenham), summer is the usual window for resealing residence bathrooms.

Before you book anyone

  • Which product they’ll use, and why it suits the joint
  • Whether primer will be used where the manufacturer specifies it
  • Will RAMS and insurance details be available?
  • How the existing material will be dealt with

How to choose a sealant contractor

Keeping South Tottenham washrooms open while we work

The 2 miles around South Tottenham include three care or nursing homes. In a care setting, a mouldy or lifting joint in a wet room is a hygiene issue as much as a cosmetic one. Work is agreed with the manager, around residents’ routines. A 2-mile radius around South Tottenham takes in a good number of hotels. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. We work a handful of rooms at a time, so the hotel keeps letting the rest.

En suites at hotels like United Lodge Hotel (1.3 miles south-west of South Tottenham) are cleaned daily, which wears silicone over time. Colleges such as Capital City College (to the north of South Tottenham) have toilets, changing rooms and catering kitchens that can be resealed around term dates.

Why it’s worth doing now in South Tottenham

Running fresh silicone along a failed bead hides the problem briefly. Silicone won’t grip silicone, so it lifts and holds moisture underneath. Cutting out completely and cleaning back takes a little longer and lasts. In a London building, a failed joint rarely affects only one party. Putting it right early is less disruptive than dealing with the consequences.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Why us?

  • Old sealant cut out, never sealed over
