Washroom sealing for Sutton sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

How we handle washroom sealing in Sutton

In a commercial washroom, sealant is normally the first thing to wear out. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning, and once mould grows into it, it can’t be scrubbed out. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. The enquiries we see most involve failed sealant behind washroom basins and open joints at the base of cubicle panels, across urinals and WCs, vanity units and basins and showers, trays and wet room floors. A specialist sealant contractor works differently from a general builder: in Sutton, that means joint design, primers and backing rod as standard.

Farm shops, cafés and venues in converted rural buildings around places like Sutton have busy toilets and kitchens. We plan the work around bookings and opening times.

Work we carry out in West Sussex comes with a 12-month guarantee. Should something we installed fail, ring 01277 525 020 or email us and we will come back to it.

How the quote is worked out

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

  • Whether the work must be split into stages
  • Access and working height
  • How much existing material needs removing
  • Which sealant the job calls for

Pricing washrooms and wet areas depends on how many there are, their condition and the access, plus any specification you are working to. Ask us for a fixed quote.

Details that help us quote

Whether it’s one area or a whole building, the same details help:

  • Asbestos survey details if the building is older
  • Specification clauses that apply
  • How the joints are reached, and at what height
  • What the building is and how it’s used

Need a figure for a tender or a budget? Send the scope and any drawings, and we’ll return a fixed quote that you can work with. For a chat about it beforehand, call the office on 01277 525 020 or email a schedule or drawings.

Wet areas in Sutton’s workplaces

At about 46 miles from central London, Sutton is within reach of the capital, within the office belt around the capital. Office washrooms on business parks see heavy weekday use, and resealing in phases keeps facilities available.

Clinical washrooms at sites like Arundel and District Hospital (to the south-east of Sutton) are scheduled with the ward so the room is out of use for as little time as possible. For a hall at a building such as The Parish Church of the Holy Cross, resealing the kitchen and toilets can be fitted between bookings.

On site: what to expect

Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. For a building around Sutton, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. We inspect each washroom and record the joints to be resealed.
  2. The fixed quote sets out the rooms, the products and the phasing.
  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. Each area is handed back when ready.

Before we start on site

  • Clear stock, furniture or equipment away from the joints
  • Let building users know which areas are affected
  • Let us know about inductions and permits

Advice

Why it’s worth doing now in Sutton

Open or mouldy joints are hard to keep hygienic which matters most in healthcare, food and education settings. Sound, smooth joints are much easier to keep clean. Around Sutton, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

What the job involves on each surface

Kitchens and tea points

In commercial kitchens, smooth, cleanable joints help keep the kitchen hygienic. Where food contact is possible, we use a hygienic, food-safe sealant.

Basins and vanity tops

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

General trades versus a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

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.

Keeping the joints sound

To get the most from the new sealant:

  • Keep extract fans working and vents clear
  • Inspect washroom sealant regularly
  • Don’t leave trays and floors sitting wet
  • Note failing joints building by building

Add washroom sealant to routine inspections. Look for black spotting, cracks, peeling edges and gaps at the busiest fittings and log what you find.

A few failed joints can be resealed with hardly any disruption. Left until every washroom is affected, it becomes a bigger programme with more phasing to plan.

FAQs: Sutton

Is Sutton too small for you to travel to?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Will the toilets in our Sutton building be out of use?

Not all at once. We take one block of facilities at a time. We will tell you the curing time for the product before we start.

Do you phase washroom resealing?

We phase it so users always have somewhere to go. We work through the building a room or section at a time. Tell us your site hours and access windows and we will plan around them.

When can showers be used after new sealant?

The silicone needs time to cure before water reaches it. Phasing is planned with the cure time in mind so facilities are never short.

Do you use special sealant for toilets and showers?

Each area gets the grade that suits it. Washrooms and showers take anti-mould sanitary silicone while kitchens may need a food-safe grade.

Do you work in hospitals, clinics and care homes?

We work in clinics, hospitals and care homes. Any records you need are confirmed with the quote before we start.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
