Washroom sealing near Dragons Green

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

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. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Jobs in and around smaller places like Dragons Green are usually planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.

  1. We inspect each washroom and record the joints to be resealed.
  2. You get a fixed quote with the phasing plan.
  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.

Getting the site ready

  • Share the asbestos register for older buildings
  • Explain the parking and delivery arrangements
  • Move anything stored against the joints

Washroom sealing for commercial buildings in Dragons Green

From one staff toilet in Dragons Green to washrooms across a whole estate, we work the same way: send details, get a fixed quote, we seal, guaranteed. Photos and a rough count of basins, urinals, showers and cubicles help us give a quick quote and a site visit is an option. The enquiries we see most involve stained sealant around pans and urinals and panel joints letting water behind, across urinals and WCs, kitchens and tea points and IPS panels and cubicles. Most enquiries from Dragons Green start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Smaller places such as Dragons Green still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Do you need washroom sealing in Dragons Green?

Washrooms are warm, damp and full of organic residue, and sealant joints trap all three. Even anti-mould grades can be colonised over time where extraction is poor.

Look out for the following:

  • Stained sealant around pans and urinals
  • Users noticing mouldy joints
  • Sealant laid over old silicone and now peeling
  • Kitchen worktop joints that can’t be kept clean

Schools such as Shipley CofE Primary School have toilets, changing rooms and kitchens that are best resealed in the holidays.

Before you book anyone

  • How they’ll work around occupants
  • Is the sealant right for the movement and the substrate?
  • Whether primer will be used where the manufacturer specifies it
  • How joint depth will be controlled

Our contractor checklist

Your questions answered

Is a hospital such as Horsham Hospital somewhere you can work?

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

Must every washroom in our Dragons Green building shut while you work?

Not all at once. We take one block of facilities at a time. Each area is handed back once the sealant has cured enough to use.

Are you fully insured?

Yes. Our insurance certificate can be sent alongside the quote.

Is old silicone taken out first?

The whole of the old bead is removed and the surfaces cleaned first. It’s the difference between a joint that lasts and one that peels.

What will the job cost?

It depends on the job: quantities, access, the product and any phasing. Call for a quote and we’ll price it properly.

How many days will you need on site?

It depends on the scope, though a typical visit normally takes a morning or so for a small washroom, longer where showers and changing rooms are included. For bigger or phased jobs, we will set out a timescale with the quote.

Is any job too small?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

After the work

Once the work is signed off, a little attention goes a long way:

  • Mention any site permits or estates rules at quote stage
  • Keep a record of which washrooms need attention
  • Brief cleaning staff to treat joints gently
  • Respect the cure time before reopening each room

Squeegeeing showers and trays after heavy use helps. Standing water on a joint all day shortens its life.

In food areas, cleanability is something environmental health officers look at. Failed sealant around sinks and worktops is easy to put right in good time.

Quoting for work in Dragons Green

These are the things that shape the price:

  • The site’s rules and procedures
  • Location, for remote and island sites
  • Which sealant the job calls for
  • The size and state of each joint

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

What we need to price the job

However big the job, these details speed things up:

  • Rough lengths or quantities, or drawings if you have them
  • Where the site is, with the postcode
  • Asbestos survey details if the building is older
  • Access details, including height

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

What happens if it’s left?

Washrooms shape how visitors judge a building. Guests, clients, pupils and patients notice stained joints before they notice much else. Fresh sanitary silicone lifts a room with very little disruption. For buildings around smaller places like Dragons Green, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

Why us?

  • Colours confirmed for the specified product
  • Fully insured, including public liability cover
  • Products installed to the manufacturer’s instructions
  • Coloured sealants to suit the setting, where available

Different surfaces, different methods

IPS and cubicle panels

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

Basins and vanity tops

Stone and some composite tops need a neutral-cure sealant and we choose a neutral-cure grade for them.
