Washroom sealing across Broomfield

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Building owners, agents and FMs in Broomfield

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

Washroom sealing in Broomfield, done properly

In a busy washroom, the sealant typically gives up long before the tiles or fittings. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning, and once mould grows into it, it can’t be scrubbed out. We strip it out and lay new anti-mould sanitary silicone. We work on accessible toilets and changing rooms, IPS panels and cubicles and vanity units and basins, and the failures we’re asked to look at most are complaints from staff, guests or users about tired washrooms and open joints at the base of cubicle panels. Most enquiries from Broomfield 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 a smaller place such as Broomfield, commercial washrooms tend to be in schools, pubs, cafés, surgeries, care homes and sports clubs. However small, each needs the old sealant removed completely and anti-mould sanitary silicone applied to clean, dry joints.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

What happens if it’s left?

Bleaching black sealant may lighten it for a few days but the growth is inside the bead and returns. A full reseal deals with it and cleaners stop fighting a losing battle. For buildings in places like Broomfield, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.

Why appoint us

  • Public liability insurance in place
  • Matching to RAL references, product permitting
  • Workmanship guaranteed for 12 months
  • CSCS-carded applicators

Commercial washrooms in Broomfield

At about 31 miles from central London, Broomfield is within reach of the capital, within the office belt around the capital. Washrooms in commuter-belt offices take constant weekday traffic, so we phase work to keep some facilities open.

Halls of residence and teaching buildings at universities such as Anglia Ruskin University (to the south of Broomfield) are easiest to reseal during vacations. Office washrooms on sites such as Regiment Business Park (0.8 miles east of Broomfield) are in use all working day, so resealing is phased to keep some open.

Broomfield is about 2 miles north of Chelmsford, in Essex. If you’re looking for washroom sealing in Broomfield, we can help. 644 places across Essex fall within our area, Broomfield among them. We also cover London, around 31 miles from Broomfield.

We cover the CM1 and CM3 postcode districts. For a building on Mandeville Way, Court Road and Gernon Close or nearby, we can quote for washrooms and wet areas. Just outside Broomfield, we also work in Little Waltham (1 mile north), Minnow End (1 mile north), Breeds (1 mile north-west), Patching (2 miles south) and Great Waltham (2 miles north-west).

What sealant work can’t fix

Some faults sit outside our scope, and we say so rather than covering them up:

  • Swollen or delaminated boards behind panels or vanity tops
  • A room that stays damp because ventilation isn’t working
  • Hollow tiles or loose panels behind the joint

Not sure which it is? You can call 01277 525 020 or email us and we’ll tell you honestly before you book.

Where we work in Broomfield

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

Surface by surface

Basins and vanity tops

Vanity tops and basins are splashed all day, so the joint to the wall and around each bowl fails early. They are resealed with anti-mould sanitary silicone.

Changing rooms and gyms

Changing rooms in gyms and leisure centres stay wet and warm, so mould is a constant battle. We use anti-mould sanitary silicone throughout.

Do you need washroom sealing in Broomfield?

Mop buckets, trolleys and knocks from users damage joints near the floor, especially at floor edges and around urinals and WC pans.

Clients usually get in touch after noticing something like this:

  • Split or peeling sealant at shower trays
  • Mould spotting along silicone joints
  • Resealing that didn’t last because the old bead stayed
  • Panel joints letting water behind

For a site such as Broomfield Hospital, which lies north-west of Broomfield, sanitary joints in clinical areas need sound, cleanable sealant and a careful method.

What to look for in a quote

  • Health and safety accreditation such as CHAS
  • What level of public liability insurance do they hold?
  • Is the sealant right for the movement and the substrate?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

Choosing a commercial sealant contractor

Our process

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. If neighbouring businesses or buildings around Broomfield need work too, visits can be combined. Tell us your site hours and we’ll plan around them.

  1. We inspect each washroom and record the joints to be resealed.
  2. The fixed quote sets out the rooms, the products and the phasing.
  3. The whole of the old bead is removed.
  4. Joints are degreased and dried.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Rooms reopen after the cure time.

What we need from you

  • For older buildings, check the asbestos register before work
  • Move anything stored against the joints
  • Send your site hours and access windows

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.

Advice

Broomfield: questions and answers

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

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Can you take on a job at a hospital such as Broomfield Hospital?

Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.

Do you guarantee washroom sealing?

Our workmanship has a 12-month guarantee, and we carry public liability insurance.

How long does a typical visit take?

It depends on the scope, though a typical visit typically takes between a morning and a week or so, set by the number of rooms and the phasing you need. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

Are you fully insured?

Yes. Our insurance certificate can be sent alongside the quote.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also phone 01277 525 020 or email a schedule or drawings. Include photographs or drawings if you have them.

How long before the toilets can reopen?

Each sealant has a cure time before it should get wet. Phasing is planned with the cure time in mind so there are always rooms open.
