Questions about Sutton

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

Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it

Will our hotel in Sutton need to close for the work?

Rarely, if ever. We take a few rooms out at a time. The plan is built around your bookings.

Do you need to remove the old sealant?

We strip every bit of the failed bead and wipe away the residue first. That’s what makes the new joint last.

Do you need to see the site first?

It depends on the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs typically get a visit.

What site paperwork can you supply?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

Will your applicators have CSCS cards?

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

Do you hold CHAS accreditation?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

How we handle washroom sealing in Sutton

We reseal washrooms and wet areas in offices, hotels, schools, universities, gyms, healthcare buildings and care homes, along with staff kitchens and tea points. Product and method follow how hard each area is used and cleaned. Site teams most often ask us about stained sealant around pans and urinals and a new bead over an old one coming away, across IPS panels and cubicles, accessible toilets and changing rooms and vanity units and basins. For commercial sealant work in Sutton, you deal with one contact from quote to sign-off, whether it’s one building or several.

Many London buildings can’t close every toilet at once. Washrooms are done core by core or floor by floor, with signage and a plan agreed beforehand, so staff and visitors can always find an open washroom.

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

When to bring in a specialist

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Different surfaces, different methods

Urinals and WC pans

We reseal around urinals and pans with a sanitary grade after the old bead and residue are removed.

Kitchens and tea points

Kitchen joints need to be smooth and sealed so they can be cleaned properly. Food-safe sealants are used where food may touch the joint.

On site: what to expect

Diagnose, treat, 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 the job ends with a walk round and sign-off. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.

  1. First, the phasing is agreed so facilities stay open.
  2. Leaks, loose panels or damp are pointed out first.
  3. Old sealant is stripped and the faces prepared.
  4. We reseal with the grade suited to each area.
  5. We confirm reopening times for each washroom.

What we need from you

  • Point out any areas we must not close
  • Share your working hours and any access restrictions
  • Share the asbestos register for older buildings

Commercial washrooms in Sutton

Busy London buildings need some toilets open at all times, so we take one block of facilities out of use at a time. Sutton has a number of hotels close by, all within 2 miles. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice.

Student showers at universities like University for the Creative Arts - Epsom (3.9 miles south-west of Sutton) see more use than most, and their silicone shows it. At a college such as Sutton College of Learning for Adults, less than half a mile south of Sutton, washroom and kitchen sealant is best renewed in the holidays or in phases during term. Staff changing rooms and patient toilets at places like Queen Mary's Childrens' Hospital, 1.1 miles north of Sutton, need cleanable, sound silicone.

Sutton is about 9 miles south of Kensington, in Greater London.

Commercial clients in Sutton

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

What sealant work can’t fix

Being straight saves everyone time. New sealant won’t cure:

  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Condensation from failed extract fans
  • Vanity carcasses that have swollen

If you’re not sure, just call 01277 525 020 or email us and we’ll give you a straight answer.

Surfaces we seal

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

Cost factors for washrooms and wet areas

Quotes vary with the job. It mainly depends on:

  • Working within restricted access windows
  • Whether old sealant has to be cut out first
  • The site’s rules and procedures
  • The product specified

The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Sending details for a quote

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

  • How the joints are reached, and at what height
  • Approximate linear metres or a joint schedule
  • Specification clauses that apply
  • The site address and postcode
