About our washroom sealing in Goathurst Common

Black spotting along a sealant bead is not a cleaning problem. The growth is inside the sealant so it returns whatever the cleaning regime. Only replacement gets rid of it for good. We work on vanity units and basins, accessible toilets and changing rooms and showers, trays and wet room floors, and what we are called in for most is failed joints along IPS and cubicle panels and failed sealant behind washroom basins. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Goathurst Common, that means joint design, primers and backing rod as standard.

Farm shops, cafés and venues in converted rural buildings around places like Goathurst Common have busy toilets and kitchens. Tell us your opening times and quiet periods and we will plan around them.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Work for main contractors and building owners

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

What affects the price in Goathurst Common

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • Specialist products, such as fire-rated or hygienic sealants
  • How accessible the joints are
  • The size and state of each joint
  • Working within restricted access windows

The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

What we need to price the job

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • A wide shot and a close-up of the area
  • The product your specification calls for
  • The type of building and who uses it
  • Whether an asbestos survey exists

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.

General trades versus a specialist

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Goathurst Common: questions and answers

Will the toilets in our Goathurst Common building be out of use?

Usually 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.

Would you work within a site like Sevenoaks Hospital?

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

How many days will you need on site?

The duration is planned around your programme and the access we’re given. We’ll give you an estimate of time on site when we quote.

Is colour matching possible?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

What if there’s asbestos in the old mastic?

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 work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

Do you hold CHAS accreditation?

Yes. We are CHAS accredited and a Constructionline member.

What happens if it’s left?

Water gets behind panels and under floors through a failed joint. In a commercial building that can mean damaged boards, stained ceilings on the floor below and odours, and fixing that takes far more work than resealing. Around Goathurst Common, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.

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 once you have the details.

Washroom sealing around Goathurst Common: what changes locally

At about 20 miles from central London, Goathurst Common is within reach of the capital. Office toilets in the commuter belt are in use from first arrivals to last departures, and resealing in phases keeps facilities available.

Where you are responsible for a hall attached to a building such as Church of St Mary at South End of Village Green, its kitchen and toilets need sealant that stays cleanable. Healthcare washrooms on sites such as Sevenoaks Hospital, 3.5 miles north-east of Goathurst Common, are resealed area by area, under the site’s own infection-control rules. If you manage an office at a site such as Salters Heath Business Centre, 1.9 miles to the north-east of Goathurst Common, the washrooms and tea points can be done a floor at a time.

Our process

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. If others near Goathurst Common need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  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. The right sanitary or food-safe sealant is applied.
  5. We give you a reopening time for every room.

Before we start on site

  • Agree which areas must stay open
  • Make sure the joints can be reached
  • Send asbestos survey details if the building is pre-2000

Quotes

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, give us a call on 01277 525 020 or email the details over.

Advice

How the job changes by surface

Wet-room floors and floor-to-wall joints

Sealant at a wet-room floor edge is not a substitute for the waterproofing underneath, and we will say if the trouble looks to be beneath the floor.

Healthcare and care settings

Healthcare work is phased so wards, clinics or residents’ areas keep their facilities. Records you need can be confirmed with the quote.
