Common questions from Rotherwick clients

Would you work within a site like Fleet Community Hospital?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

Is Rotherwick too far out for you?

No. Places such as Rotherwick are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Do you need to remove the old sealant?

We always remove it. Fresh silicone can’t key to an old bead, so sealing over it soon peels.

Is it possible to just clean mouldy silicone?

Surface cleaning won’t reach mould that has rooted into the bead. New anti-mould sanitary silicone is the treatment and point out if ventilation is part of the problem.

Do you do washroom sealing in healthcare settings?

Yes. Your infection-control rules, estates requirements and permits are followed. The work is phased around patients or residents.

How long does a typical visit take?

That varies with the scale of the job, but the work typically takes a morning or so for a small washroom, longer where showers and changing rooms are included. For bigger or phased jobs, we’ll set out a timescale with the quote.

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 around your site hours and access windows.

How we handle washroom sealing in Rotherwick

For clinics, hospitals and care homes, sealed joints matter for infection control as much as appearance. We work to your organisation’s estates and infection-control requirements and any site permits. Any records you need are confirmed with the quote. If you are dealing with black mould inside silicone joints that cleaning can’t shift and urinal joints that look unhygienic, we can help, on IPS panels and cubicles, vanity units and basins and showers, trays and wet room floors alike. A single leaking joint is often how a building in Rotherwick first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

In and around smaller places like Rotherwick, 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 is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Keeping Rotherwick washrooms open while we work

Rotherwick lies roughly 40 miles out from central London. Office washrooms on business parks see heavy weekday use, and resealing in phases keeps facilities available. Several hotels sit less than 2 miles from Rotherwick. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. We work a handful of rooms at a time, so the hotel keeps letting the rest.

On a healthcare site such as Fleet Community Hospital, 5.5 miles east of Rotherwick, washroom work starts with the infection-control team’s sign-off. For buildings on a site such as Optrex Business Centre, 0.9 miles to the south-west of Rotherwick, washrooms and tea points can be resealed in phases through the working week. Hotels such as Tylney Hall Hotel (1.1 miles south-west of Rotherwick) have en suite bathrooms where tired silicone at the bath, tray and basin is replaced room by room.

Rotherwick is about 6 miles west of Fleet, in Hampshire. We cover Rotherwick and the rest of Hampshire, with the same fixed quotes and 12-month guarantee as everywhere else. 723 places across Hampshire fall within our area, including Rotherwick. For work in that direction, see our Reading page (10 miles or so).

Work on washrooms and wet areas is covered throughout RG27, for business premises of every kind. We cover commercial and managed buildings on The Street, Wedman's Lane and Hook Road and the roads nearby. Nearby places we also cover include Lyde Green (1 mile north-west), Mattingley (1 mile north-east), Hound Green (2 miles north-east), Hazeley (2 miles north-east) and Heckfield (3 miles north). Further afield, our area takes in Basingstoke (6 miles south-west), Farnborough (9 miles east), Fleet (6 miles east), Aldershot (10 miles south-east), Alton (11 miles south) and Yateley (6 miles east).

Around Rotherwick

Locally, jobs take us to sites close to Coach And Horses Public House and the streets around them. Rotherwick’s nearest station is Hook station, about 1.8 miles south of the centre. A little further out are West Green House Agricultural Museum (1.8 miles east) and Fleet Community Hospital (5.5 miles east). Green spaces nearby include Dogmersfield Lake and The Mill Field.

On site: what to expect

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work normally takes a few hours for one toilet block, with bigger buildings phased across a number of visits. Jobs in and around smaller places like Rotherwick are usually planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  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.

Getting the site ready

  • Send asbestos survey details if the building is pre-2000
  • Warn occupants and staff about the work
  • Arrange parking or a loading space

Quotes

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Advice

When to bring in a specialist

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.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

Leave it or put it right?

When a washroom looks worn, a refit isn’t the only answer. If the finishes are in good order, replacing the sealant may do much of what’s needed for now. Converted and older buildings near places like Rotherwick tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

A quote for washrooms and wet areas depends on how many there are, their condition and the access. Call for a quote.

What the job involves on each surface

Basins and vanity tops

Stone and some composite tops need a neutral-cure sealant, so the product is chosen to suit.

Wet-room floors and floor-to-wall joints

Wet floors are common in accessible showers and changing rooms, so their perimeter joints get close attention.

After the work

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Clear standing water from shower floors where possible
  • Brief cleaning staff to treat joints gently
  • Report split joints at trays and basins early
  • Note failing joints building by building

Where possible, have shower floors and trays squeegeed after busy periods. Joints that sit wet for hours fail sooner.

Small numbers of failed joints are quick to phase in. Left, it tends to become a building-wide job with more phasing to plan.

Building owners, agents and FMs in Rotherwick

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, with each stage agreed with your site contact.

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Rotherwick can sit alongside others in a wider programme across Hampshire.
