Washroom sealing in Harbledown

Black spotting along a sealant bead is not a cleaning problem. The growth is inside the sealant, which is why it comes back however often it is treated. Replacing the bead is the lasting treatment. If you have mould spotting along silicone joints and sealant laid over old silicone and now peeling, we can help. For commercial sealant work in Harbledown, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

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

We stand by our work: 12 months, guaranteed. That covers our preparation and application.

Busy facilities in and around Harbledown

At about 52 miles from central London, Harbledown is within reach of the capital, in a commuter belt where offices and business parks are common. Washrooms in commuter-belt offices take constant weekday traffic, which is why the work is phased. Four care or nursing homes sit less than 2 miles from Harbledown. Care home wet rooms and en suites are used every day and cleaned hard, which tells on the silicone. We plan the work with the manager so residents are disturbed as little as possible.

For an occupier at a site such as Wincheap Industrial Estate, 0.8 miles to the south-east of Harbledown, the canteen and welfare facilities need cleanable joints as much as any office. For centre management at a site such as Whitefriars Shopping Centre, 1.1 miles east of Harbledown, washroom work is planned around footfall.

Harbledown is about 1 mile west of Canterbury, in Kent. Commercial clients in Harbledown can call on us for washrooms and wet areas. 931 places across Kent fall within our area, including Harbledown. There’s a separate page for London, roughly 52 miles from Harbledown.

Commercial clients in Harbledown

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.

We work for building owners and managing agents on everything from one building to a spread of sites around Harbledown. Several sites can go on one quote, which keeps the paperwork simple.

From enquiry to sign-off

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. Rural sites near Harbledown may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. We agree which washrooms close and when.
  2. Leaks, loose panels or damp are pointed out first.
  3. Old sealant is stripped and the faces prepared.
  4. We reseal with the grade suited to each area.
  5. We confirm reopening times for each washroom.

Preparing the site

  • Tell us what induction or permit system the site runs
  • Send any specification or drawings in advance
  • Send asbestos survey details if the building is pre-2000

Ask for a quote

A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or call the office on 01277 525 020 or email us to discuss it first.

Related advice

Site staff or a sealant specialist?

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

What happens if it’s left?

Water gets behind panels and under floors through a failed joint. That can lead to swollen boards, marked ceilings below and lingering smells which costs more to fix than a reseal. Converted and older buildings near places like Harbledown tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Details that help us quote

To price the job accurately, we need to understand the site. Useful things to include:

  • The type of building and who uses it

Your questions answered

Will you work in a care home in Harbledown without moving residents out?

Yes. Care settings are planned area by area, at times agreed with the home. We follow the home’s own procedures throughout.

Is Harbledown off your patch?

Not at all. Harbledown is within our area. London and every South East county are within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Can you clean the mould off instead of resealing?

Not for long. Mould grows into the sealant itself, so it comes back however often it’s cleaned. Replacing the bead is the lasting answer.

Do you hold CHAS accreditation?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.

What sealant do you use in washrooms?

Sanitary silicone with anti-mould additives in most cases. Neutral-cure grades are used where acetoxy types could mark metals, stone or mirror backings.

Do you work in hospitals, clinics and care homes?

We work in clinics, hospitals and care homes. Tell us what records you need and we will confirm with the quote.

Which sealant will you use?

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.

Common problems we fix in Harbledown

Panels and vanity units move slightly in use, and shower trays shift under foot. If the joint wasn’t laid to take that movement, it tears or peels away.

Look out for the following:

  • Open joints at the base of cubicle panels
  • Black mould inside silicone joints that cleaning can’t shift
  • Washrooms that look worn because of the sealant
  • Open joints along basins and vanity units

For a college such as Canterbury College, 1.5 miles east of Harbledown, half-term and summer give the windows for washroom work.
