Washroom sealing for Swanmore sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Building owners, agents and FMs in Swanmore

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first.

Washroom sealing in Swanmore

When mould has spotted a silicone joint, more cleaning won’t remove it. The mould has rooted into the silicone itself, which is why it comes back however often it is treated. Only replacement gets rid of it for good. If you have sealant laid over old silicone and now peeling and mould spotting along silicone joints, we can help, on IPS panels and cubicles, kitchens and tea points and vanity units and basins alike. Most enquiries from Swanmore start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Pub and restaurant kitchens around smaller places like Swanmore work hard on their joints. Sealed joints at sinks, worktops and splashbacks help keep the kitchen cleanable.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Signs you need washroom sealing in Swanmore

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 peels away quickly.

It’s worth sending us details if you spot any of the following:

  • Open joints at the base of cubicle panels
  • Failed sealant behind washroom basins
  • Users noticing mouldy joints
  • Sealant laid over old silicone and now peeling

On a healthcare site such as Knowle Hospital, which lies south of Swanmore, washroom work starts with the infection-control team’s sign-off.

Questions to ask before you book

  • Whether old or failed sealant will be cut out, not overlaid
  • How the joint faces will be prepared and primed
  • How joint depth will be controlled
  • Whether their applicators hold CSCS cards

Choosing a commercial sealant contractor

What the job involves on each surface

Healthcare and care settings

Accessible and assisted washrooms are used and cleaned intensively, so their joints often need renewing sooner.

IPS and cubicle panels

Cubicle and IPS panels move when leaned on or knocked, so the sealant has to take that movement. We check fixings before sealing.

Questions about Swanmore

Can you take on a job at a hospital such as Knowle Hospital?

Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is Swanmore too far out for you?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.

Will you quote for a small job?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

How do you choose the sealant?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

How long does a typical visit take?

We plan the time on site around your programme and access. You’ll have an expected duration with the quote.

Are you CHAS accredited and on Constructionline?

Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Do you do washroom sealing in healthcare settings?

We do. Your infection-control rules, estates requirements and permits are followed, and phase the work so areas keep facilities.

From enquiry to sign-off

Site rules come first: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For a job in Swanmore, the main thing is a clear picture of the work. A fixed quote follows.

  1. Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
  2. The phasing is agreed so there are always facilities open.
  3. We strip out the old bead and clean off the residue left behind.
  4. We clean and dry every surface so the new sealant can grip.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. You get a reopening time for every room, with signage left up until then.

Preparing the site

  • Tell staff and tenants when we’ll be in
  • Send your site hours and access windows
  • Point out parking and an unloading spot

Request a quote

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, call 01277 525 020 or use the quote form.

Related advice

When something else is needed

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:

  • A room that stays damp because ventilation isn’t working
  • Fittings that move too much to hold a bead
  • Vanity carcasses that have swollen

If in doubt, call 01277 525 020 or send details through our quote form and we will say what we think.

Joints and surfaces we work on

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

Cost factors for washrooms and wet areas

A fixed quote reflects the actual work. It allows for:

  • Any access equipment needed
  • Which sealant the job calls for
  • Joint width, depth and condition
  • Site requirements such as inductions and permits

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Before you send an enquiry

We can often quote from photographs and a few details. Please tell us:

  • Whether an asbestos survey exists
  • Access details, including height
  • What the building is and how it’s used
  • Any dates the work must fit around

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.
