How a job runs

Inspect, seal, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Smaller jobs around Groombridge can be grouped with others nearby, 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. Failed sealant and residue are stripped out.
  4. We reseal with the grade suited to each area.
  5. We give you a reopening time for every room.

Preparing the site

  • Clear stock, furniture or equipment away from the joints
  • Flag any permit to work we’ll need
  • Warn occupants and staff about the work

Advice

Do you need washroom sealing in Groombridge?

Daily commercial cleaning wears sealant faster than people expect. Strong chemicals, scourers and jet washing roughen, discolour or lift a bead, and dirt and mould then get a foothold.

Look out for the following:

  • Mould spotting along silicone joints
  • Open joints along basins and vanity units
  • Washrooms that look worn because of the sealant
  • Split or peeling sealant at shower trays

For a school such as Groombridge St Thomas' Church of England Primary School, washroom and kitchen sealant can be renewed around term dates.

What to look for in a quote

  • Will CSCS-carded applicators be on site?
  • Their approach to joint depth and backing
  • How the joint faces will be prepared and primed
  • What site paperwork they can supply

Our contractor checklist

Different surfaces, different methods

Changing rooms and gyms

Changing rooms can be phased so one stays open. Tell us your site hours and access windows and we will plan around them.

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.

Questions we are asked in Groombridge

Can you work around term dates at a campus such as Canterbury Christ Church University - Salomons?

Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Is hospital work, at somewhere like Tunbridge Wells Homeopathic Hospital, something you do?

Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.

Are you fully insured?

Yes. We’re fully insured, and the certificate can go with your quote.

When can showers be used after new sealant?

That varies with the sealant and the room temperature. Each room gets its own reopening time from us, and signs stay up until then.

Do you need to see the site first?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.

What happens if old sealant might contain asbestos?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

Keeping Groombridge washrooms open while we work

Central London is about 29 miles from Groombridge, 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.

Halls of residence and teaching buildings at universities such as Canterbury Christ Church University - Salomons, 3.7 miles to the north-east of Groombridge, are easiest to reseal during vacations. Halls linked to places like Church of St Thomas the Apostle host groups all week, which is hard on kitchen and toilet sealant.

Groombridge is about 4 miles south-west of Royal Tunbridge Wells, in East Sussex.

What affects the price in Groombridge

These are the things that shape the price:

  • Travel to remote or island sites
  • Site requirements such as inductions and permits
  • The size and state of each joint
  • How much there is to seal

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.

What to include in your enquiry

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

  • Approximate linear metres or a joint schedule
  • How the joints are reached, and at what height
  • When you need the work done
  • A wide shot and a close-up of the area

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.

Honest limits

Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:

  • Failed tanking beneath a wet-room floor or behind tiles
  • A dripping waste or valve behind a panel
  • Fittings that move too much to hold a bead

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

Surfaces we seal

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

Commercial clients in Groombridge

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
