Washroom sealing in Goodnestone

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Our process

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Smaller jobs around Goodnestone can be grouped with others nearby, which keeps travel down. You will have a fixed quote before work starts.

  1. We survey each room, count the joints and note anything behind them that needs another 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. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. You get a reopening time for every room, with signage left up until then.

Preparing the site

  • Warn occupants and staff about the work
  • Move anything stored against the joints
  • Let us know about inductions and permits

Advice

How we handle washroom sealing in Goodnestone

Closing all the facilities in a building isn’t an option. We phase the work one washroom, one bank of cubicles or one changing room at a time, so staff, guests or pupils always have somewhere to go. Tell us your site hours and access windows and we’ll plan around them. If you are dealing with black mould inside silicone joints that cleaning can’t shift and a new bead over an old one coming away, we can help. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Goodnestone is the same: the right product in a properly prepared joint.

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

Work we carry out in Kent comes with a 12-month guarantee. If an installation problem shows up, call the office on 01277 525 020 or email us and we’ll arrange a return visit.

Signs you need washroom sealing in Goodnestone

Low-level joints get hit by mop buckets, cleaning trolleys and feet at skirting lines, urinal bases and around pans.

Site and facilities staff are often the first to spot these:

  • Users noticing mouldy joints
  • Failed sealant in a tea point or staff kitchen
  • Black mould inside silicone joints that cleaning can’t shift
  • Stained sealant around pans and urinals

At a hospital like St Martins Hospital (5.7 miles west of Goodnestone), patient and staff washrooms are best done in short phases agreed with the ward.

What your quote should include

  • Is the sealant right for the movement and the substrate?
  • Their pre-qualification and accreditations
  • Will failed sealant be removed rather than covered?
  • Their public liability cover

Toilets, showers and kitchens around Goodnestone

Central London is about 60 miles from Goodnestone, in a commuter belt where offices and business parks are common. Office toilets in the commuter belt are in use from first arrivals to last departures, which is why the work is phased.

For a school such as Goodnestone Church of England Primary School, washroom and kitchen sealant can be renewed around term dates. Where you’re responsible for a hall attached to a building such as Church of the Holy Cross, its kitchen and toilets need sealant that stays cleanable.

Quoting for work in Goodnestone

What shapes the price:

  • Site requirements such as inductions and permits
  • Whether old sealant has to be cut out first
  • Access and working height
  • Whether the work must be split into stages

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.

Sending details for a quote

A good diagnosis starts with the right details. Let us know:

  • Whether an asbestos survey exists
  • Whether the building will be occupied during the work
  • When you need the work done
  • The postcode of the building

Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

FAQs: Goodnestone

Will all the washrooms in our Goodnestone building be closed at once?

Normally only some of them, for a short time. We work in phases so other facilities stay open. Sanitary silicone needs time to cure before the area is used, and we’ll tell you how long for the product used.

Is Goodnestone too small for you to travel to?

No. Places such as Goodnestone are covered as much as the big towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

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 many days will you need on site?

That varies with the scale of the job, but the work typically takes a few hours for one toilet block, with bigger buildings phased across a number of visits. For bigger or phased jobs, we’ll set out a timescale with the quote.

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

Can weather delay the job?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Which silicone is right for commercial washrooms?

Each area gets the grade that suits it. Most washroom joints take sanitary silicone, and food areas take a hygienic, food-safe sealant where food contact is possible.

Why deal with it now?

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 which costs more to fix than a reseal. Converted and older buildings near places like Goodnestone tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

There’s no price list, because the scope varies so much from one building to the next. Call for a quote.

Why appoint us

  • Colours chosen to suit frames, cladding or finishes where possible
  • Colours confirmed for the specified product
  • Joints cleaned back to sound surfaces
  • Work carried out by CSCS-carded applicators

See our cost guide or our accreditations and insurance.

What the job involves on each surface

IPS and cubicle panels

Panels flex slightly in use so the bead needs to cope with it. We check fixings before sealing.

Urinals and WC pans

Pan and urinal joints face constant cleaning and splashing. Once they discolour or split, they hold odours and make the room look neglected.

For managing agents and facilities managers

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

If you look after buildings for someone else, 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.
