Washroom sealing in Stubbles: the local picture

Stubbles is about 46 miles from central London, in a commuter belt where offices and business parks are common. Office washrooms on business parks see heavy weekday use, so we work a block of facilities at a time.

Around Stubbles, washroom joints are resealed by removing the old silicone completely and laying anti-mould sanitary silicone on dry surfaces. Where you’re responsible for a hall attached to a building such as Church of St Clement, its kitchen and toilets need sealant that stays cleanable.

Stubbles is about 7 miles north-east of Thatcham, in West Berkshire. We cover commercial sites throughout Stubbles, whether it’s a single job or part of a planned programme. We work across 140 places in West Berkshire. Our Reading page has more on work in that area.

Honest limits

We check first that sealant really is the fix. It isn’t the answer for:

  • Fittings that move too much to hold a bead
  • A dripping waste or valve behind a panel
  • Water escaping beneath the floor rather than through a joint

Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we will tell you honestly.

Where we work in Stubbles

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

Looking after the joints

Cleaning and maintenance staff play a part too. Share these points with them:

  • Include joints in routine washroom inspections
  • Clean sealant with gentle products and a soft cloth
  • Leave signs up until the cure time is over
  • Note failing joints building by building

If a joint we sealed fails within 12 months, tell us and we will look at it. After that, a routine look catches failing joints early.

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

Questions we’re asked in Stubbles

What site paperwork comes with a job in Stubbles?

We will confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We hold £5m public liability insurance, are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded.

Is Stubbles too far out for you?

No. Small places get the same service as large ones. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Can the sealant be colour-matched?

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

What sealant do you use in washrooms?

It depends on the joint. Most washroom joints take sanitary silicone while kitchens may need a food-safe grade.

Do you do washroom sealing in healthcare settings?

Yes, healthcare and care settings are part of our work. Any records you need are confirmed with the quote.

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. We don’t remove asbestos-containing materials.

Will your applicators have CSCS cards?

Yes. Our applicators hold CSCS cards, which many sites require.

Doing it in-house

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

What the job involves on each surface

Basins and vanity tops

A failed joint along a vanity unit lets water into the carcass. Resealing early protects the unit.

IPS and cubicle panels

Cubicle and IPS panels move when leaned on or knocked so the bead needs to cope with it. We check fixings before sealing.

Diagnose, treat, sign off

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes a few hours for one toilet block, with bigger buildings phased across a number of visits, and we clear our waste as we work. For a building around Stubbles, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. We inspect each washroom and record the joints to be resealed.
  2. The fixed quote sets out the rooms, the products and the phasing.
  3. Old sealant is removed completely and the faces cleaned.
  4. Joints are degreased and dried.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Each area is handed back when ready.

Before we start on site

  • Send asbestos survey details if the building is pre-2000
  • Send your site hours and access windows
