Need washroom sealing in Brook?

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Our process

At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. Jobs in and around smaller places like Brook are typically planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
  2. A phasing plan keeps part of the building’s facilities in use at all times.
  3. We strip out the old bead and clean off the residue left behind.
  4. Joints are cleaned, degreased and dried before sealing.
  5. New sanitary silicone with anti-mould additives goes in and is tooled neat.
  6. Rooms reopen after the product’s cure time, and we move to the next.

Getting the site ready

  • Make sure the joints can be reached
  • Confirm the product named in the specification
  • Warn occupants and staff about the work

Getting a fixed quote

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.

Washroom sealing in Brook

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. The enquiries we see most involve urinal joints that look unhygienic and sealant lifting along a tray edge, on accessible toilets and changing rooms, vanity units and basins and kitchens and tea points. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Brook, that means joint design, primers and backing rod as standard.

Smaller places such as Brook still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Sealant that has gone black with mould normally can’t be cleaned, so it is cut out and replaced.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

How the quote is worked out

Your fixed quote is built from the real scope. It allows for:

  • Removal of failed or old sealant
  • Whether the work must be split into stages
  • Joint width, depth and condition
  • Which sealant the job calls for

We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.

Sending details for a quote

Good information means a firmer quote. When you get in touch, include:

  • Where the site is, with the postcode
  • Specification clauses that apply
  • How the joints are reached, and at what height
  • Your programme or deadline

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, ring 01277 525 020 or email us.

For managing agents and facilities managers

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

We work for building owners and managing agents on everything from one building to a spread of sites around Brook. Several sites can go on one quote, which keeps the paperwork simple.

Washroom sealing around Brook: how the place shapes the job

Brook is about 51 miles from central London. Office washrooms on business parks see heavy weekday use, which is why the work is phased.

Staff changing rooms and patient toilets at places like WIlliam Harvey Hospital, 2.3 miles south-west of Brook, need cleanable, sound silicone. At a school such as Brook Community Primary School, changing rooms and kitchens need cleanable joints as much as the toilets.

Brook is about 4 miles east of Ashford, in Kent. We send applicators to Brook for washrooms and wet areas, handled exactly as we handle every other area. Brook is one of 931 places we cover in Kent for washrooms and wet areas. We also cover London, around 51 miles from Brook.

Work on washrooms and wet areas is covered throughout TN25. Buildings on The Street, Troy Town Lane and Stonebridge are within our area. Just outside Brook, we also work in Folly Town (1 mile east), Wye (2 miles north-west), Hinxhill (2 miles south-west), Hastingleigh (2 miles east) and Hassell Street (2 miles north-east). Bigger towns within reach include Ashford (4 miles west), Canterbury (10 miles north-east), Dover (15 miles east), Folkestone (11 miles south-east), Whitstable (14 miles north) and Faversham (11 miles north).

What’s near Brook

We work on buildings around Wye School and the streets around them. The nearest railway station is Wye station, roughly 2 miles north-west of the centre. Other landmarks nearby include William Harvey Hospital (2.4 miles south-west) and County Square (3.9 miles west). Green spaces nearby include Hatch Park.

Questions we’re asked in Brook

Would you work within a site like WIlliam Harvey Hospital?

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 Brook building shut while you work?

Normally 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.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, tell us and we will confirm them with the quote.

Who decides which product is used?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

How long does a job like this take?

It depends on the scope, though a typical visit typically takes half a day to a day per washroom, depending on the number of fittings. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

Can you quote from photos?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.

What if there’s asbestos in the old mastic?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

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 as well as site permits.

IPS and cubicle panels

A panel that has already swollen won’t be fixed by sealant, and any we come across will be pointed out.

Common problems we fix in Brook

Washrooms are warm, damp and full of organic residue, and silicone joints hold onto all three. Even anti-mould grades can be colonised over time where extraction is poor.

Things that usually lead to an enquiry:

  • Gaps where vanity tops meet the wall
  • Black mould inside silicone joints that cleaning can’t shift
  • Resealing that didn’t last because the old bead stayed
  • Discoloured joints around urinals and WC pans

For a hall at a building such as Church of St Mary, resealing the kitchen and toilets can be fitted between bookings.

Before you book anyone

  • Health and safety accreditation such as CHAS
  • Can the work be phased to keep areas open?
  • How the existing material will be dealt with
  • Whether their applicators hold CSCS cards

How to choose a sealant contractor

General trades versus a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

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