Washroom sealing in Wickham Common, done properly

Black spotting along a sealant bead is not a cleaning problem. The mould has rooted into the silicone itself so it returns whatever the cleaning regime. Only replacement gets rid of it for good. If you have kitchen worktop joints that can’t be kept clean and washrooms that look worn because of the sealant, we can put it right. Most enquiries from Wickham Common start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Community buildings around smaller places like Wickham Common have kitchens and toilets used by many people. Resealing sinks, worktops and WCs with anti-mould silicone keeps them clean and watertight.

Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Do you need washroom sealing in Wickham Common?

Sometimes the sealant fails because something behind it is moving or wet: loose fixings, a dripping trap or damp in the wall. We check for that first and tell you if another trade is needed.

Any of the following is a good reason to get the joints checked over:

  • Open joints at the base of cubicle panels
  • Mould spotting along silicone joints
  • Urinal joints that look unhygienic
  • Kitchen worktop joints that can’t be kept clean

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

What to look for in a quote

  • Will failed sealant be removed rather than covered?
  • Their approach to joint depth and backing
  • Will CSCS-carded applicators be on site?
  • Their public liability cover

Choosing a commercial sealant contractor

Diagnose, treat, sign off

On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, and the work usually takes a few hours for one toilet block, with bigger buildings phased across a number of visits. For work around Wickham Common, we aim to finish in one visit, so photos and measurements up front really help. 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. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. Joints are cleaned, degreased and dried before sealing.
  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.

Getting the site ready

  • Tell us which areas need to stay in use
  • Share the asbestos register for older buildings
  • Send your site hours and access windows

Related advice

When to bring in a specialist

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

At a hotel such as The Old House Hotel (1 mile north-west of Wickham Common), the quieter weeks are the time to reseal bathrooms. Office washrooms on sites such as Knowle Village Business Park (1.7 miles west of Wickham Common) are in use all working day, so resealing is phased to keep some open.

After the work

To get the most from the new sealant:

  • Tell us about infection-control or permit rules before we quote
  • Keep washrooms out of use until we say the sealant has cured
  • Don’t leave trays and floors sitting wet
  • Report split joints at trays and basins early

Ask your cleaning team to use gentle products and soft cloths on sealant. Strong acids, solvents and scourers wear the surface and give mould a start.

Small numbers of failed joints are quick to phase in. Left, it tends to become a building-wide job and more closures to manage.

What sets the cost

To price the job, we consider:

  • Working within restricted access windows
  • How much existing material needs removing
  • Which sealant the job calls for
  • Backing rod, priming and other preparation

What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote when you are ready.

Details that help us quote

Good information means a firmer quote. Helpful details to send:

  • A wide shot and a close-up of the area
  • How the joints are reached, and at what height
  • The asbestos register, for older buildings
  • Any dates the work must fit around

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, call 01277 525 020 or email drawings and photos.

For managing agents and facilities managers

If you look after buildings for someone else, 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.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Questions we are asked in Wickham Common

Is Wickham Common too small for you to travel to?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Must every washroom in our Wickham Common building shut while you work?

Rarely all at once: work is phased so some facilities are always available. We’ll tell you the curing time for the product before we start.

Does the weather affect the work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Is there a guarantee on the work?

Our workmanship has a 12-month guarantee, and we carry public liability insurance.

What happens if old sealant might contain asbestos?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. 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.

Are your applicators CSCS-carded?

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

Is colour matching possible?

That depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
