How we handle washroom sealing in Thorney

Since 2005 we have resealed commercial washrooms for facilities teams, contractors and building owners. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We are fully insured. Every resealed washroom carries our 12-month guarantee. If you have panel joints letting water behind and complaints from staff, guests or users about tired washrooms, we can help, whatever the surface. One point of contact handles commercial sealant work in Thorney from the first photographs to the final walk-round, for single jobs and planned programmes alike.

Halls and community buildings near places like Thorney are used by different groups through the week, and their toilets and kitchens show it. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

How a job runs

At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. Jobs in and around smaller places like Thorney are usually planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. Every room is surveyed and the failed joints listed.
  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. New anti-mould sealant goes in and is tooled neat.
  6. Each area is handed back when ready.

What we need from you

  • Clear stock, furniture or equipment away from the joints
  • Share the asbestos register for older buildings
  • Explain the parking and delivery arrangements

Ask for a quote

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.

Advice

What sealant work can’t fix

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Failed tanking beneath a wet-room floor or behind tiles
  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • A room that stays damp because ventilation isn’t working

If in doubt, phone 01277 525 020 or email drawings and photos and we will say what we think.

What we seal

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

What affects the price in Thorney

Quotes vary with the job. Expect it to depend on:

  • Removal of failed or old sealant
  • Induction, permit and paperwork requirements
  • How much there is to seal
  • Working within restricted access windows

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Before you send an enquiry

We can often quote from photographs and a few details. It helps to include:

  • Whether an asbestos survey exists
  • When you need the work done
  • The site address and postcode
  • Access details, including height

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

For managing agents and facilities managers

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

What the job involves on each surface

IPS and cubicle panels

Cubicle and IPS panels move when leaned on or knocked so the bead needs to cope with it. We check fixings before sealing.

Wet-room floors and floor-to-wall joints

Floor edges in wet areas are where water most often escapes. Floor perimeters and sealant joints near drains are resealed.

Your questions answered

Can work at a site such as Brunel University of London fit around teaching?

Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Is Thorney too small for you to travel to?

No. Small places get the same service as large ones. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Which sealant will you use?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Do you take on small jobs?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

Do you need to remove the old sealant?

We always remove it. New silicone won’t stick to the old, so sealing over it soon peels.

How many days will you need on site?

The duration is planned around your programme and the access we are given. You will have an expected duration with the quote.

How long will the new sealant last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Should maintenance staff do it?

Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
