Washroom sealing near Christmas Common

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

How we handle washroom sealing in Christmas Common

For clinics, hospitals and care homes, sealed joints matter for infection control as much as appearance. Your estates and infection-control requirements, and any permits the site uses, shape how we work. Any records you need are confirmed with the quote. If you’re dealing with mould spotting along silicone joints and shower tray joints that have opened up, we can put it right, whatever the surface. Whoever orders the work in Christmas Common, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

Community buildings around smaller places like Christmas Common have kitchens and toilets used by many people. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.

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.

When it isn’t the sealant

Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:

  • A dripping waste or valve behind a panel
  • Loose panels, vanity units or tiles, which need fixing first
  • Leaks through tanking or membranes below the finishes

If in doubt, call 01277 525 020 or use the quote form and we will say what we think.

Joints and surfaces we work on

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

How the quote is worked out

Your fixed quote is built from the real scope. It takes account of:

  • Whether old sealant has to be cut out first
  • The total length or number of joints
  • Which sealant the job calls for
  • Working within restricted access windows

The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.

Before you send an enquiry

To price the job accurately, we need to understand the site. Send us:

  • Clear photos of the problem areas
  • Access details, including height
  • Rough lengths or quantities, or drawings if you have them
  • Any specification or named product

A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or give us a call on 01277 525 020 or use the quote form if you’d rather talk the job through.

Different surfaces, different methods

Showers and trays

Shower trays move under foot and are wet all day. Tray joints are where many washroom leaks start.

Changing rooms and gyms

Gym and leisure changing rooms see showers running most of the day so sealant there works very hard. Anti-mould sanitary silicone is the standard choice.

Our process

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes a morning or so for a small washroom, longer where showers and changing rooms are included, and we clear our waste as we work. Rural sites near Christmas Common may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  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. Each joint is cleaned and left dry.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Each area is handed back when ready.

Before we start on site

  • Tell us your opening times and when work is allowed
  • Make sure the joints can be reached
  • Arrange parking or a loading space

Advice

Owners, agents and contractors

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

Do you need washroom sealing in Christmas Common?

A lot of failed washroom sealant was laid over an old bead or a dirty surface. New silicone won’t grip the old, so it soon lets go.

Typical triggers for a call:

  • Stained or open joints at kitchen sinks and worktops
  • Sealant lifting along a tray edge
  • Discoloured joints around urinals and WC pans
  • Open joints at the base of cubicle panels

Where you’re responsible for a hall attached to a building such as Church of the Nativity, its kitchen and toilets need sealant that stays cleanable.

What your quote should include

  • Will CSCS-carded applicators be on site?
  • Will RAMS and insurance details be available?
  • Which product they’ll use, and why it suits the joint
  • Are they CHAS accredited or on Constructionline?

FAQs: Christmas Common

Is a smaller place like Christmas Common outside your area?

Not at all. Christmas Common is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

What documents will you need to give us for a job in Christmas Common?

RAMS, insurance certificate, CSCS details: list what the site needs and we’ll confirm it with the quote. We are CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.

Do you need to see the site first?

That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs usually get a visit.

Can you reseal washrooms in healthcare buildings?

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

Can you handle several sites?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

How do you deal with asbestos in old sealant?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

Is there a guarantee on the work?

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