Questions we are asked in Tooting Bec

Can you work around term dates at a campus such as University of the Arts London?

Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Would you work within a site like St George's Hospital?

Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Do you do washroom sealing in healthcare settings?

We work in clinics, hospitals and care homes. Tell us what records you need and we’ll confirm with the quote before we start.

How do I request a quote?

You can use the quote form on this site; alternatively, phone 01277 525 020 or email drawings and photos. Photos, drawings or a joint schedule help us quote quickly.

Do you need to see the site first?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit.

Who decides which product is used?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Do you cover Tooting Bec?

Yes. Tooting Bec is in our area, within our coverage of Greater London, South East England and Scotland. To discuss a job, call the office on 01277 525 020 or send photos by email.

Washroom sealing in Tooting Bec, done properly

In a commercial washroom, sealant is typically the first thing to wear out. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day, and once mould grows into it, it can’t be scrubbed out. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. If you have sealant laid over old silicone and now peeling and washrooms that look worn because of the sealant, we can help. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Tooting Bec, that means joint design, primers and backing rod as standard.

Building managers in Tooting Bec normally 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: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

When something else is needed

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:

  • Water from plumbing, not from a joint
  • Panel boards already damaged by water
  • Condensation from failed extract fans

If you’re not sure, just call 01277 525 020 or use the quote form and we’ll give you a straight answer before you book.

Joints and surfaces we work on

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

How the job changes by surface

Wet-room floors and floor-to-wall joints

Changing rooms and accessible showers often have wet floors so the edges are checked carefully.

Showers and trays

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

When to call us in Tooting Bec

Mop buckets, trolleys and knocks from users damage joints near the floor at skirting lines, urinal bases and around pans.

Common reasons buildings call us in:

  • Failed sealant behind washroom basins
  • Urinal joints that look unhygienic
  • A new bead over an old one coming away
  • Sealant stained black around basins and showers

For a campus such as University of the Arts London (3.3 miles north of Tooting Bec), showers in residences and washrooms in teaching blocks can be programmed around term dates.

Choosing a commercial sealant contractor

Cost factors for washrooms and wet areas

A fixed quote reflects the actual work. It takes account of:

  • Which sealant the job calls for
  • Joint width, depth and condition
  • Whether old sealant has to be cut out first
  • Travel to remote or island sites

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

What to include in your enquiry

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • When you need the work done
  • Where the site is, with the postcode
  • Whether an asbestos survey exists
  • How the joints are reached, and at what height

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

En suites at hotels like Antoinette Hotel (to the south-west of Tooting Bec) are cleaned daily, which wears silicone over time. Healthcare washrooms on sites such as St George's Hospital, less than half a mile to the west of Tooting Bec, are resealed area by area, under the site’s own infection-control rules.

Advice

Work for main contractors and building owners

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.

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