Your questions answered

Can you work on a hospital site such as Braintree Community Hospital?

Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is a smaller place like Causeway End outside your area?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Is there a guarantee on the work?

A 12-month guarantee covers the work. It covers our workmanship rather than damage, leaks from plumbing or ventilation problems.

Is it OK to put new silicone on top of the old?

We always remove it. Fresh silicone can’t key to an old bead, so sealing over it soon peels.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

How do I request a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.

Does weather matter for sealant work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

Washroom sealing around Causeway End: what changes locally

Central London is about 33 miles from Causeway End. Office washrooms on business parks see heavy weekday use, so we work a block of facilities at a time.

Pupil toilets at schools like Felsted Primary School take heavy daily use, and the holidays give the window to reseal. Clinical washrooms at sites like Braintree Community Hospital (4.6 miles north-east of Causeway End) are scheduled with the ward so the room is out of use for as little time as possible.

Causeway End is about 6 miles south-west of Braintree, in Essex. Across the CM6 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. 644 places across Essex fall within our area, including Causeway End. For work in that direction, see our London page, about 33 miles away.

Business premises anywhere in CM6 are within our area. Among the streets we cover are Jollyboys Lane South, Chelmsford Road and Causeway End Road. You will find Causeway End on or near the B1417. We also cover Felsted (1 mile north), Watch House Green (1 mile north-east), Bannister Green (1 mile north-east), North End (1 mile south-west) and Little Dunmow (1 mile north-west). Further afield, our area takes in Chelmsford (8 miles south), Braintree (6 miles north-east), Harlow (15 miles west), Maldon (13 miles south-east), Billericay (15 miles south) and Witham (9 miles east).

Common problems we fix in Causeway End

Washrooms are warm, damp and full of organic residue, and silicone joints hold onto all three. Anti-mould additives help, but in a poorly ventilated room mould can still take hold eventually.

Common reasons buildings call us in:

  • Users noticing mouldy joints
  • Gaps where vanity tops meet the wall
  • Black mould inside silicone joints that cleaning can’t shift
  • Failed joints along IPS and cubicle panels

Welfare facilities in units on estates such as Martels Industrial Estate, 2.6 miles west of Causeway End, have showers, toilets and kitchens with sealant that works hard.

Questions to ask before you book

  • Which product they’ll use, and why it suits the joint
  • How long is the guarantee, and what does it include?
  • How the joint faces will be prepared and primed
  • Who will actually carry out the work

Questions to ask before you appoint anyone

Diagnose, treat, sign off

At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. For a building around Causeway End, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. We agree which washrooms close and when.
  2. Leaks, loose panels or damp are pointed out first.
  3. Old sealant is stripped and the faces prepared.
  4. The right sanitary or food-safe sealant is applied.
  5. We give you a reopening time for every room.

Before we start on site

  • Point out any areas we must not close
  • Have the specification and drawings to hand
  • Make sure the joints can be reached

Getting a fixed quote

The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or speak to us on 01277 525 020 or email drawings and photos if you’d rather talk the job through.

General trades versus a specialist

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

What the job involves on each surface

Healthcare and care settings

Clinics, hospitals and care homes need joints that can be kept clean. We work to your estates and infection-control requirements and any permits the site uses.

Showers and trays

If a tray moves too much or is cracked, it needs attention first and we flag that beforehand.

When it isn’t the sealant

Honesty saves time and money. Fresh joints won’t solve:

  • Loose panels, vanity units or tiles, which need fixing first
  • A room that stays damp because ventilation isn’t working
  • Vanity carcasses that have swollen

Not sure which it is? You can ring 01277 525 020 or email the details over and we will tell you honestly.

What we seal

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