Washroom sealing for Bannister Green sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

On site: what to expect

Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before we move to the next. Rural sites near Bannister Green may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  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.

Getting the site ready

  • Have the specification and drawings to hand
  • Clear stock, furniture or equipment away from the joints
  • Agree which areas must stay open

Request a quote

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

How we handle washroom sealing in Bannister Green

Black spotting along a sealant bead is not a cleaning problem. The growth is inside the sealant so it returns whatever the cleaning regime. Only replacement gets rid of it for good. If you have split or peeling sealant at shower trays and sealant laid over old silicone and now peeling, we can put it right, on kitchens and tea points, IPS panels and cubicles and accessible toilets and changing rooms alike. Facilities teams, main contractors and managing agents in Bannister Green tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Rural businesses near smaller places such as Bannister Green, from cafés to event venues, rely on washrooms and kitchens that stay clean. Tell us your opening times and quiet periods and we’ll plan around them.

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Your questions answered

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

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

Must every washroom in our Bannister Green building shut while you work?

Typically only some of them, for a short time. We work in phases so other facilities stay open. Sanitary silicone needs time to cure before the area is used, and we will tell you how long for the product used.

What about RAMS and site documents?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

What’s the quickest route to a quote?

There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.

Can you work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

Is there a guarantee on the work?

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

What happens if old sealant might contain asbestos?

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.

When something else is needed

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

  • A room that stays damp because ventilation isn’t working
  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Leaks through tanking or membranes below the finishes

If in doubt, give us a call on 01277 525 020 or send details through our quote form and we will say what we think before you book.

What we seal

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

Keeping Bannister Green washrooms open while we work

Central London is about 35 miles from Bannister Green. Office washrooms on business parks see heavy weekday use, so we phase work to keep some facilities open.

On a healthcare site such as Braintree Community Hospital, which lies north-east of Bannister Green, washroom work starts with the infection-control team’s sign-off. Office washrooms on sites such as Concord Farm Business Centre (1.7 miles east of Bannister Green) are in use all working day, so resealing is phased to keep some open. Pupil toilets at schools like Felsted Primary School take heavy daily use, and the holidays give the window to reseal.

Bannister Green is about 4 miles west of Braintree, in Essex. We cover commercial sites throughout Bannister Green. 644 places across Essex fall within our area, including Bannister Green. Sites around London have their own page, roughly 35 miles from Bannister Green.

Business premises anywhere in CM6 are within our area for washrooms and wet areas. Among the streets we cover are Stevens Lane, Cressages Close and Burnstie Road, and sites on any of them can send details for a fixed quote. Just outside Bannister Green, we also work in Watch House Green (1 mile north-west), Felsted (1 mile west), Causeway End (1 mile south-west), Blake End (1 mile north) and Willows Green (2 miles south-east). Nearby towns on our patch include Chelmsford (9 miles south), Braintree (4 miles east), Maldon (13 miles south-east), Witham (8 miles south-east), Saffron Walden (15 miles north-west) and Halstead (9 miles north-east).

Aftercare for building managers

To get the most from the new sealant:

  • Tell us about infection-control or permit rules before we quote
  • Report faulty extraction promptly
  • Act on the first split you see at a shower tray
  • Squeegee showers and trays after busy periods

We hand each area back once the silicone has had the cure time the product needs. You will be told when showers and basins can be used again and signage stays in place until that time.

Inspectors look at whether kitchen surfaces can be kept clean. Failed sealant around sinks and worktops is easy to put right in good time.

Quoting for work in Bannister Green

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • How accessible the joints are
  • Removal of failed or old sealant
  • The total length or number of joints
  • Phasing around occupants

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

What we need to price the job

The more we know, the firmer the quote. When you get in touch, include:

  • Clear photos of the problem areas
  • Your programme or deadline
  • The asbestos register, for older buildings
  • The type of building and who uses it

For a fixed quote, speak to us on 01277 525 020 or send details through our quote form with the site address and an outline of the work. You can also send details through our quote form.

Owners, agents and contractors

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

What happens if it’s left?

Leaving the job until a shutdown often means living with it for months. With phasing, the work can go ahead while most facilities stay open. One visit to deal with every failing joint makes more sense than several trips to a place like Bannister Green. Send photographs of each area and we will quote for the lot.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.
