Washroom sealing across Boreham

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

Washroom sealing in Boreham

Whether it’s a single toilet block in Boreham or a programme across several buildings, the route is the same: details first, then a fixed quote, then the work, then the 12-month guarantee. Photos and a rough count of basins, urinals, showers and cubicles help us give a quick quote and a site visit is an option. The enquiries we see most involve washrooms that look worn because of the sealant and stained or open joints at kitchen sinks and worktops, on IPS panels and cubicles, showers, trays and wet room floors and kitchens and tea points. Whoever orders the work in Boreham, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

Jobs in a smaller place such as Boreham are often one building: a school’s toilets, a café kitchen, a surgery’s washrooms. A list and photographs let us quote and plan so it’s done in one visit where possible.

Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Sanitary sealant for Boreham buildings

At about 33 miles from central London, Boreham is within reach of the capital, within the office belt around the capital. Office washrooms on business parks see heavy weekday use, which is why the work is phased.

Toilets at places like Chelmer Village Retail Park (2.8 miles south-west of Boreham) are cleaned constantly, so silicone needs to be sound and smooth. Staff changing rooms and patient toilets at places like Springfield Hospital, 2.5 miles to the west of Boreham, need cleanable, sound silicone.

Boreham is about 3 miles north-east of Chelmsford, in Essex. Boreham sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. Boreham is one of 644 places in Essex on our list for washrooms and wet areas. We also cover London, around 33 miles from Boreham.

We take on washrooms and wet areas across the CM3 postcode area. For a building on Church Road, St Andrews Road and Seabrook Gardens or nearby, send details and we’ll quote for washrooms and wet areas. Being close to the B1137, Boreham is easy to get to with materials and equipment. Just outside Boreham, we also work in Mowden (1 mile east), Springfield (2 miles south-west), Little Baddow (2 miles south-east), Hatfield Peverel (2 miles north-east) and Sandon (3 miles south). Bigger towns within reach include Chelmsford (3 miles south-west), Basildon (14 miles south), Braintree (8 miles north), Brentwood (14 miles south-west), Maldon (6 miles east) and Billericay (11 miles south-west).

Work for main contractors and building owners

We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, which keeps the paperwork simple.

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first.

Diagnose, treat, sign off

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes a few hours for one toilet block, with bigger buildings phased across a number of visits, and our waste is bagged and taken away as we go. If neighbouring businesses or buildings around Boreham need work too, visits can be combined. Tell us your site hours and we’ll plan around them.

  1. Every room is surveyed and the failed joints listed.
  2. You get a fixed quote with the phasing plan.
  3. The whole of the old bead is removed.
  4. Joints are degreased and dried.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Each area is handed back when ready.

Preparing the site

  • Share your working hours and any access restrictions
  • Point out any areas we must not close
  • Clear stock, furniture or equipment away from the joints

Questions about Boreham

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

Yes. We plan campus work around teaching, exams and residence turnarounds. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Is Boreham too far out for you?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Are you CHAS accredited and on Constructionline?

Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.

Can you send site paperwork?

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

When is resealing likely to be due?

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

Can washrooms stay open while you work?

We phase it so users always have somewhere to go. We work through the building a room or section at a time. Tell us your site hours and access windows and we’ll plan around them.

What happens if old sealant might contain asbestos?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

How the quote is worked out

Quotes vary with the job. It mainly depends on:

  • Backing rod, priming and other preparation
  • Phasing around occupants
  • The product specified
  • Whether old sealant has to be cut out first

No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Sending details for a quote

A good diagnosis starts with the right details. Tell us:

  • Your programme or deadline
  • Rough lengths or quantities, or drawings if you have them
  • Asbestos survey details if the building is older
  • Clear photographs of the problem areas

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.

Surface by surface

Changing rooms and gyms

Gym and leisure changing rooms see showers running most of the day so sealant there works very hard. We use anti-mould sanitary silicone throughout.

IPS and cubicle panels

Cubicle and IPS panels move when leaned on or knocked, so the sealant has to take that movement. We check fixings before sealing.

What we’re called out for in Boreham

Panels and vanity units move slightly in use, and shower trays shift under foot. A bead that can’t cope with the movement splits along one edge.

Any of the following is a good reason to get the joints checked over:

  • Gaps where vanity tops meet the wall
  • A new bead over an old one coming away
  • Shower tray joints that have opened up
  • Discoloured joints around urinals and WC pans

At a university such as Anglia Ruskin University, 3.2 miles to the south-west of Boreham, summer is the usual window for resealing residence bathrooms.

Questions to ask before you book

  • Whether old or failed sealant will be cut out, not overlaid
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Which product they’ll use, and why it suits the joint
  • Who will actually carry out the work

How to choose a sealant contractor

General trades versus a specialist

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
