Common questions from Swallows Cross clients

Is hospital work, at somewhere like Brentwood Community Hospital, something you do?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

Must every washroom in our Swallows Cross 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.

Will you come and look before quoting?

It depends on the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.

Can you clean the mould off instead of resealing?

Cleaning may lighten it, but the mould returns. We replace the sealant with an anti-mould sanitary grade and check the ventilation isn’t the cause.

Does weather matter for sealant work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Which silicone is right for commercial washrooms?

An anti-mould sanitary silicone for most washroom joints. We use neutral-cure versions on stone, some metals and near mirrors.

How many days will you need on site?

We plan the time on site around your programme and access. You will have an expected duration with the quote.

Washroom sealing for commercial buildings in Swallows Cross

Not every silicone belongs in a washroom. Sanitary grades carry anti-mould additives, and neutral-cure types are used where acetoxy silicone could attack some metals, stone or mirror backings. In food areas, hygienic or food-safe sealants are used where food contact is possible. We work on vanity units and basins, IPS panels and cubicles and showers, trays and wet room floors, and what we’re called in for most is open joints along basins and vanity units and stained or open joints at kitchen sinks and worktops. A specialist sealant contractor works differently from a general builder: in Swallows Cross, that means joint design, primers and backing rod as standard.

Halls and community buildings near places like Swallows Cross are used by different groups through the week, and their toilets and kitchens show it. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Quoting for work in Swallows Cross

The price varies from site to site. Expect it to depend on:

  • The total length or number of joints
  • The size and state of each joint
  • Travel to remote or island sites
  • Removal of failed or old sealant

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Details that help us quote

However big the job, the same details help:

  • Anything awkward about access or site hours
  • Drawings or a marked-up plan, if available
  • Any specification or named product
  • Any dates the work must fit around

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

Why it’s worth doing now in Swallows Cross

A tired-looking washroom doesn’t always need a refurbishment. If the finishes are in good order, replacing the sealant may do much of what’s needed while bigger works are planned. One visit to deal with every failing joint makes more sense than several trips to a place like Swallows Cross. Send photos of each area and we will quote for the lot.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Why appoint us

  • Coloured sealants to suit the setting, where available
  • One number for every site we cover
  • Colour options checked against the specified product
  • Products installed to the manufacturer’s instructions

Read what affects the cost and our accreditations.

Keeping the joints sound

Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:

  • Don’t leave an open joint at a basin or tray
  • Keep extract fans working and vents clear
  • Inspect washroom sealant regularly
  • Brief cleaning staff to treat joints gently

Where possible, have shower floors and trays squeegeed after busy periods. Joints that sit wet for hours fail sooner.

Water getting behind IPS panels and vanity units can swell the boards. Once that happens, a reseal won’t fix them.

Diagnose, treat, sign off

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For work around Swallows Cross, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.

  1. We agree which washrooms close and when.
  2. Anything behind the joints that needs another trade is flagged.
  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.

Getting the site ready

  • Agree which areas must stay open
  • Let us know about inductions and permits
  • Send your site hours and access windows

Advice

Keeping Swallows Cross washrooms open while we work

Swallows Cross is about 22 miles from central London. Office washrooms on business parks see heavy weekday use, so we phase work to keep some facilities open.

Clinical washrooms at sites like Brentwood Community Hospital (to the south of Swallows Cross) are scheduled with the ward so the room is out of use for as little time as possible. For a school such as Shenfield High School, washroom and kitchen sealant can be renewed around term dates.

Swallows Cross is about 3 miles north-east of Brentwood, in Essex. We cover Swallows Cross, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. We work across 644 places in Essex, from busy centres to rural villages. London is covered too, some 22 miles away.

Postcode districts covered here: CM15 for washrooms and wet areas. We cover commercial and managed buildings on Thoby Lane and Wyatt's Green Road. Nearby places we also cover include Wyatt's Green (1 mile north-west), Green Street (1 mile north-east), Mountnessing (1 mile south-east), Doddinghurst (1 mile west) and Beggar Hill (2 miles north-east) for washrooms and wet areas. A short drive away, we cover Chelmsford (8 miles north-east), Basildon (8 miles south-east), Harlow (12 miles north-west), Brentwood (3 miles south-west), Canvey Island (15 miles south-east) and Billericay (5 miles south-east).

Building owners, agents and FMs in Swallows Cross

If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

Doing it in-house

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
