How we handle washroom sealing in Howegreen

Black spotting along a sealant bead is not a cleaning problem. The mould has rooted into the silicone itself, which is why it comes back however often it is treated. Replacing the bead is the lasting treatment. We work on urinals and WCs, accessible toilets and changing rooms and IPS panels and cubicles, and the failures we are asked to look at most are sealant stained black around basins and showers and failed sealant in a tea point or staff kitchen. Facilities teams, main contractors and managing agents in Howegreen tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

In and around smaller places like Howegreen, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Sealant that has gone black with mould typically can’t be cleaned, so it is cut out and replaced.

We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Signs you need washroom sealing in Howegreen

Commercial cleaning is harder on sealant than everyday use. Harsh products, abrasive pads and pressure washing break down a joint’s surface and edges, and dirt and mould then get a foothold.

Common reasons buildings call us in:

  • Open joints at the base of cubicle panels
  • Shower tray joints that have opened up
  • Failed sealant in a tea point or staff kitchen
  • Mould spotting along silicone joints

Pupil toilets at schools like Purleigh Community Primary School take heavy daily use, and the holidays give the window to reseal.

What to look for in a quote

  • Their approach to joint depth and backing
  • Who will actually carry out the work
  • Whether primer will be used where the manufacturer specifies it
  • Whether old or failed sealant will be cut out, not overlaid

Questions to ask before you appoint anyone

Questions we’re asked in Howegreen

Is a smaller place like Howegreen outside your area?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

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

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

Are you CHAS accredited?

Yes. We are CHAS accredited and a Constructionline member.

Do you do washroom sealing in healthcare settings?

We work in clinics, hospitals and care homes. Any records you need are confirmed with the quote before we start.

Is any job too small?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Can you quote from photos?

Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.

Who decides which product is used?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

General trades versus a specialist

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

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

Our process

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. Jobs in and around smaller places like Howegreen are typically planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. A phasing plan keeps part of the building’s facilities in use at all times.
  3. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. We clean and dry every surface so the new sealant can grip.
  5. New sanitary silicone with anti-mould additives goes in and is tooled neat.
  6. You get a reopening time for every room, with signage left up until then.

Before we start on site

  • Point out parking and an unloading spot
  • Send asbestos survey details if the building is pre-2000
  • Flag any permit to work we will need

How the quote is worked out

We price every job individually. The main factors are:

  • How much existing material needs removing
  • Backing rod, priming and other preparation
  • The product specified
  • Distance, for remote addresses

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Before you send an enquiry

For an accurate fixed quote, we need to understand the site. Send us:

  • When you need the work done
  • Drawings or a marked-up plan, if available
  • Specification clauses that apply
  • How the joints are reached, and at what height

Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. To get it moving, phone 01277 525 020 or send details through our quote form.

What sealant work can’t fix

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Water escaping beneath the floor rather than through a joint
  • Panel boards already damaged by water
  • A dripping waste or valve behind a panel

Not sure which it is? You can phone 01277 525 020 or email drawings and photos and we’ll tell you honestly.

Joints and surfaces we work on

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

Leave it or put it right?

Sealing on top of old silicone saves nothing. Silicone won’t grip silicone, so it lifts and holds moisture underneath. Cutting out completely and cleaning back takes a little longer and lasts. Converted and older buildings near places like Howegreen tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Why us?

  • Work to your specification and the manufacturer’s guidance
  • A range of standard colours, depending on the product
  • Sealing commercial buildings since 2005
  • 12 months’ guarantee on every job
