About our washroom sealing in Headington

Washroom joints need the right sealant, not whatever is to hand. Sanitary silicone contains additives that resist mould, and neutral-cure types are used where acetoxy silicone could attack some metals, stone or mirror backings. In food areas, hygienic or food-safe sealants are used where food contact is possible. We work on showers, trays and wet room floors, accessible toilets and changing rooms and kitchens and tea points, and the failures we’re asked to look at most are stained sealant around pans and urinals and failed sealant behind washroom basins. For commercial sealant work in Headington, you deal with one contact from quote to sign-off, whether it’s one building or several.

In a smaller place such as Headington, commercial washrooms tend to be in schools, pubs, cafés, surgeries, care homes and sports clubs. They don’t need a big crew, but they do need old sealant fully cut out before anti-mould silicone goes on.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Headington: questions and answers

Would you work within a site like John Radcliffe Hospital?

Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Can work in a care setting near Headington go ahead while residents are there?

Yes, with the manager deciding the order and timing of rooms. Any site rules, from signing in to infection control, are agreed before we start.

Is any job too small?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Can weather delay the job?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

Owners, agents and contractors

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

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Headington can sit alongside others in a wider programme.

Washroom sealing around Headington: points for this area

Central London is about 51 miles from Headington. Washrooms in commuter-belt offices take constant weekday traffic, which is why the work is phased. The area within 2 miles of Headington holds several hotels. En suite bathrooms, staff changing rooms and kitchens all need their sanitary silicone renewed in time. We work a handful of rooms at a time, so the hotel keeps letting the rest.

Toilets at colleges like Oxford Sixth Form College, 2 miles to the south-west of Headington, take heavy use from students and staff alike. Healthcare estates like John Radcliffe Hospital (less than half a mile west of Headington) expect contractors to follow their permits and cleaning rules in every washroom. For centre management at a site such as Clarendon Shopping Centre, which lies south-west of Headington, washroom work is planned around footfall.

Headington is about 1 mile north-east of Oxford, in Oxfordshire. We cover commercial sites throughout Headington. Headington is one of 423 places in Oxfordshire on our list.

What sets the cost

What shapes the price:

  • The total length or number of joints
  • Travel to remote or island sites
  • Specialist products, such as fire-rated or hygienic sealants
  • Whether the work must be split into stages

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.

Details that help us quote

However big the job, these details speed things up:

  • A wide shot and a close-up of the area
  • Access details, including height
  • What the building is and how it’s used
  • Rough lengths or quantities, or drawings if you have them

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.

When it isn’t the sealant

Honesty saves time and money. Fresh joints won’t solve:

  • Water from plumbing, not from a joint
  • Failed tanking beneath a wet-room floor or behind tiles
  • Panel boards already damaged by water

If you’re not sure, just phone 01277 525 020 or use the quote form and we’ll give you a straight answer before you book.

What we seal

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

Different surfaces, different methods

Urinals and WC pans

The joint between a pan and the floor is easy to overlook. They are checked with everything else.

IPS and cubicle panels

Panel systems meet walls, floors and vanity tops at sealed joints. Those joints protect the boards behind from water.

Maintenance after handover

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Mention any site permits or estates rules at quote stage
  • Keep washrooms out of use until we say the sealant has cured
  • Clear standing water from shower floors where possible
  • Clean sealant with gentle products and a soft cloth

Where possible, have shower floors and trays squeegeed after busy periods. Standing water on a joint all day shortens its life.

Water getting behind IPS panels and vanity units can swell the boards. After that, those parts need replacing rather than resealing.

Our process

Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Work in places the size of Headington is planned as a single visit where we can. Clear photos and measurements help us bring the right products.

  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. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Rooms reopen after the cure time.

Preparing the site

  • Send asbestos survey details if the building is pre-2000
  • Let building users know which areas are affected
  • Let us know about inductions and permits

Get a fixed quote

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
