About our washroom sealing in Marley

Facilities managers, contractors and building owners have used us for washroom sealing for over 20 years. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We are fully insured. Our workmanship is guaranteed for 12 months. The enquiries we see most involve shower tray joints that have opened up and failed sealant behind washroom basins, across urinals and WCs, IPS panels and cubicles and vanity units and basins. For commercial sealant work in Marley, you deal with one contact from quote to sign-off, whether it’s one building or several.

In and around smaller places like Marley, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

  1. Every room is surveyed and the failed joints listed.
  2. The fixed quote sets out the rooms, the products and the phasing.
  3. The whole of the old bead is removed.

General trades versus a specialist

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

Questions we’re asked in Marley

Do we have to close all our washrooms in Marley for resealing?

Usually only some of them, for a short time. We work in phases so other facilities stay open. We will tell you the curing time for the product before we start.

Is a smaller place like Marley outside your area?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

What guarantee comes with washroom resealing?

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

Do you offer coloured sealant?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.

How do you deal with asbestos in old sealant?

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.

Can you reseal washrooms in healthcare buildings?

Yes. We work to your estates and infection-control requirements and any site permits, and phase the work so areas keep facilities.

Are you insured?

Yes. We’re fully insured, including public liability cover.

After the work

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

  • Brief cleaning staff to treat joints gently
  • Clear standing water from shower floors where possible
  • Share your site rules when you send details
  • Keep a record of which washrooms need attention

Squeegeeing showers and trays after heavy use helps. Joints that sit wet for hours fail sooner.

Inspectors look at whether kitchen surfaces can be kept clean. Resealing sinks, worktops and splashbacks before an inspection is a simple step.

Keeping Marley washrooms open while we work

At about 38 miles from central London, Marley is within reach of the capital. Office toilets in the commuter belt are in use from first arrivals to last departures, so we phase work to keep some facilities open.

Pupil toilets at schools like Harrietsham Church of England Primary School take heavy daily use, and the holidays give the window to reseal. Where you are responsible for a hall attached to a building such as St John the Baptist's Church, its kitchen and toilets need sealant that stays cleanable.

Marley is about 7 miles east of Maidstone, in Kent. Anywhere in ME17, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Marley is one of 931 places we cover in Kent for washrooms and wet areas. There’s a separate page for London, about 38 miles away.

Postcode districts covered here: ME17 for washrooms and wet areas. Among the streets we cover are Parks Road, Young Lane and Church Lane, and sites on any of them can send details for a fixed quote. Close to Marley, our area also takes in Harrietsham (1 mile west), Pollhill (1 mile west), Sandway (1 mile south-east), Platt's Heath (1 mile south) and Chegworth (2 miles west).

Different surfaces, different methods

Wet-room floors and floor-to-wall joints

Changing rooms and accessible showers often have wet floors so the edges are checked carefully.

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.

Signs you need washroom sealing in Marley

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.

Look out for the following:

  • Open joints along basins and vanity units
  • Sealant stained black around basins and showers
  • Stained or open joints at kitchen sinks and worktops
  • Split or peeling sealant at shower trays

For a campus such as Canterbury Christ Church University, which lies north of Marley, showers in residences and washrooms in teaching blocks can be programmed around term dates.

How to choose a sealant contractor

What sets the cost

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

  • Access and working height
  • The site’s rules and procedures
  • Backing rod, priming and other preparation
  • The total length or number of joints

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.

Before you send an enquiry

The more we know, the firmer the quote. Helpful details to send:

  • Drawings or a marked-up plan, if available
  • When you need the work done
  • Where the site is, with the postcode
  • Anything awkward about access or site hours

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.
