Washroom sealing across Otford

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

What happens if it’s left?

Leaving the job until a shutdown often means living with it for months. With phasing, the work can go ahead while most facilities stay open. Small buildings around Otford suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.

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.

Washroom sealing in Otford

You can’t shut every toilet in an office, school or hotel at once. We phase the work one washroom, one bank of cubicles or one changing room at a time, so there are always facilities in use. Give us your site hours and access windows and the phasing is planned around them. The enquiries we see most involve sealant stained black around basins and showers and failed sealant in a tea point or staff kitchen, across kitchens and tea points, IPS panels and cubicles and accessible toilets and changing rooms. Whether you call it commercial sealant work, mastic application or joint sealing, in Otford it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

In a smaller place such as Otford, commercial washrooms tend to be in schools, pubs, cafés, surgeries, care homes and sports clubs. They don’t need a big crew, but they do need old sealant fully cut out before anti-mould silicone goes on.

Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

Toilets, showers and kitchens around Otford

Otford has a number of hotels close by, all within 2 miles. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time. We work a handful of rooms at a time, so the hotel keeps letting the rest. At about 18 miles from central London, Otford is within reach of the capital, within the office belt around the capital. Business park offices have washrooms in daily use by staff, so we work a block of facilities at a time.

Office washrooms on sites such as Goya Business Park Sevenoaks, 1.1 miles to the south of Otford, are in use all working day, so resealing is phased to keep some open. On a healthcare site such as Sevenoaks Hospital, which lies south of Otford, washroom work starts with the infection-control team’s sign-off. For a school such as Otford Primary School, washroom and kitchen sealant can be renewed around term dates.

Otford is about 2 miles north of Sevenoaks, in Kent. We cover Otford, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. 931 places across Kent fall within our area, Otford among them. For work in that direction, see our London page (18 miles or so).

Doing it in-house

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

FAQs: Otford

Do hotels near Otford have to close for sealant work?

Almost never. The work is phased so most rooms stay available. Housekeeping and our team agree each day’s rooms.

Is Otford too far out for you?

No. Places such as Otford are covered as much as the big towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

How long does a typical visit take?

That varies with the scale of the job, though a typical visit usually takes a few hours for one toilet block, with bigger buildings phased across a number of visits. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Is it OK to put new silicone on top of the old?

The failed bead is always removed. Fresh silicone can’t key to an old bead so a bead over the top fails quickly.

Do you take on multi-site work?

Yes. A group of buildings can go on one quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

Are you insured?

Yes. We’re fully insured, including public liability cover.

Is there a guarantee on the work?

Every job carries our 12-month guarantee. It covers our workmanship rather than damage, leaks from plumbing or ventilation problems.

Aftercare for building managers

Keep the joints in good shape with a few simple steps:

  • Make sure washroom ventilation is running
  • Clear standing water from shower floors where possible
  • Keep a record of which washrooms need attention
  • Report split joints at trays and basins early

We hand each area back once the silicone has had the cure time the product needs. We’ll tell you when the wet areas can be used, and it helps if signs stay up until then.

Mould in a joint spreads along the bead and into nearby grout, and complaints follow. Replacing it early keeps the job to a reseal.

From enquiry to sign-off

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, and the work normally takes between a morning and a week or so, set by the number of rooms and the phasing you need. Work in places the size of Otford is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.

  1. Every room is surveyed and the failed joints listed.
  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. Rooms reopen after the cure time.

What affects the price in Otford

Before we quote, we look at:

  • Location, for remote and island sites
  • Phasing around occupants
  • Induction, permit and paperwork requirements
  • Which sealant the job calls for

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

What we need to price the job

A few photos plus some basic facts will normally do. It helps to include:

  • Whether an asbestos survey exists
  • Any specification or named product
  • Your programme or deadline
  • A wide shot and a close-up of the area

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

Work for main contractors and building owners

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’ll confirm them with the quote.

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Otford can form part of a wider programme.
