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

Washroom sealing in Upper Clatford, done properly

Not every silicone belongs in a washroom. Sanitary grades carry anti-mould additives, and neutral-cure types are used where acetoxy silicone could attack some metals, stone or mirror backings. Where food contact is possible, we use a hygienic, food-safe grade. If you are dealing with urinal joints that look unhygienic and stained or open joints at kitchen sinks and worktops, we can put it right, on showers, trays and wet room floors, accessible toilets and changing rooms and IPS panels and cubicles alike. Whoever orders the work in Upper Clatford, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

In and around smaller places like Upper Clatford, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Sealant that has gone black with mould normally can’t be cleaned, so it is cut out and replaced.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Keeping the joints sound

Cleaning and maintenance staff play a part too. Share these points with them:

  • Keep washrooms out of use until we say the sealant has cured
  • Clear standing water from shower floors where possible
  • Act on the first split you see at a shower tray
  • Add sealant joints to planned maintenance checks

Any failure in our workmanship within the 12-month guarantee is ours to put right. After that, a routine look catches failing joints early.

Small numbers of failed joints are quick to phase in. Left until every washroom is affected, it becomes a bigger programme and more closures to manage.

From enquiry to sign-off

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work typically takes a few hours for one toilet block, with bigger buildings phased across a number of visits. Jobs in and around smaller places like Upper Clatford are typically planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. We agree which washrooms close and when.
  2. Anything behind the joints that needs another trade is flagged.
  3. Failed sealant and residue are stripped out.
  4. The right sanitary or food-safe sealant is applied.
  5. We give you a reopening time for every room.

Preparing the site

  • Point out any areas we must not close
  • Clear stock, furniture or equipment away from the joints
  • Have the specification and drawings to hand

How the job changes by surface

Basins and vanity tops

A failed joint along a vanity unit lets water into the carcass. Resealing early protects the unit.

When to bring in a specialist

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Common questions from Upper Clatford clients

Is Upper Clatford off your patch?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Will our hotel in Upper Clatford need to close for the work?

In the majority of cases no closure is needed: we work room by room or floor by floor. The plan is built around your bookings.

Does the weather affect the work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Can you quote from photos?

That depends on the size and complexity of the job. Simple work can often be priced from photos, and bigger or more complex jobs typically get a visit.

What sealant do you use in washrooms?

Sanitary silicone with anti-mould additives for most washroom joints. We use neutral-cure versions on stone, some metals and near mirrors.

Can you send site paperwork?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

Are you CHAS accredited and on Constructionline?

Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.

What affects the price in Upper Clatford

What shapes the price:

  • The product specified
  • The site’s rules and procedures
  • Any access equipment needed
  • How much existing material needs removing

What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.

Sending details for a quote

There’s no need for a formal survey. A few details are enough to get going:

  • Specification clauses that apply
  • Your programme or deadline
  • Asbestos survey details if the building is older
  • Approximate linear metres or a joint schedule

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.
