Sanitary sealant for Coscote buildings

There are four care or nursing homes within about 2 miles of Coscote. In care settings, wet rooms, assisted bathrooms and en suites rely on clean, sound sealant. We plan the work with the manager so residents are disturbed as little as possible. Coscote is about 50 miles from central London. Washrooms in commuter-belt offices take constant weekday traffic, so we work a block of facilities at a time.

Church halls and community buildings, such as those at Church of St Andrew, have kitchens and toilets used by many groups, and their sanitary sealant works hard. At a hotel such as The Kingswell Hotel, 1.1 miles west of Coscote, the quieter weeks are the time to reseal bathrooms. Schools such as Hagbourne Church of England Primary School have toilets, changing rooms and kitchens that are best resealed in the holidays.

Coscote is about 1 mile south of Didcot, in Oxfordshire. Anywhere in OX11, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed.

About our washroom sealing in Coscote

In healthcare and care settings, sealing is part of keeping surfaces cleanable. We work to your organisation’s estates and infection-control requirements and any site permits. Tell us what records you need and we will confirm with the quote. Site teams most often ask us about users noticing mouldy joints and failed sealant behind washroom basins, on accessible toilets and changing rooms, urinals and WCs and IPS panels and cubicles. Whoever orders the work in Coscote, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

Smaller places such as Coscote 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.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Why deal with it now?

Sealing on top of old silicone saves nothing. It doesn’t bond, so it peels and traps dirt behind it. Full removal and proper cleaning is what makes the new joint last. One visit to deal with every failing joint makes more sense than several trips to a place like Coscote. Photos of every joint help us quote for the whole job.

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 fixed quote and we will explain how it’s made up.

What you get with us

  • Work to your specification and the manufacturer’s guidance
  • Health and safety: CHAS accredited
  • A range of standard colours, depending on the product
  • CSCS-carded applicators

Building owners, agents and FMs in Coscote

CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.

Building owners and managing agents use us on everything from one building to a spread of sites. Several sites can go on one quote, so there’s one set of paperwork to deal with.

How a job runs

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Smaller jobs around Coscote can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. We agree which rooms close and when, so users always have somewhere to go.
  3. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. Rooms reopen after the product’s cure time, and we move to the next.

Preparing the site

  • Arrange parking or a loading space
  • Let building users know which areas are affected
  • Let us know about inductions and permits

What sets the cost

Your fixed quote is built from the real scope. It allows for:

  • Any access equipment needed
  • Distance, for remote addresses
  • The site’s rules and procedures
  • Specialist products, such as fire-rated or hygienic sealants

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Sending details for a quote

However big the job, the same details help:

  • Clear photos of the problem areas
  • The type of building and who uses it
  • The site address and postcode
  • When you need the work done

Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. For a chat about it beforehand, call 01277 525 020 or send photos by email.

Questions about Coscote

Can you work on a hospital site such as Didcot Hospital?

Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Can you work in a care home near Coscote with residents in?

Yes. Care settings are planned area by area, at times agreed with the home. Tell us about any infection-control or safeguarding requirements and we will work to them.

Is it possible to just clean mouldy silicone?

Typically not. Mould grows into the sealant itself, so it comes back however often it’s cleaned. Replacement is the lasting fix.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

Is it OK to put new silicone on top of the old?

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.

Will your applicators have CSCS cards?

Yes. We use CSCS-carded applicators, as many construction sites ask for.

When something else is needed

A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:

  • A dripping waste or valve behind a panel
  • Failed tanking beneath a wet-room floor or behind tiles
  • Swollen or delaminated boards behind panels or vanity tops

If in doubt, phone 01277 525 020 or use the quote form and we will say what we think.

Joints and surfaces we work on

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

Site staff or a sealant specialist?

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

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.
