Washroom sealing in Hungerford

Our washroom work covers offices, hotels, schools and colleges, leisure centres and gyms, clinics and care homes, along with staff kitchens and tea points. The products and the method are chosen for how heavily each space is used. The enquiries we see most involve failed sealant behind washroom basins and sealant lifting along a tray edge, across IPS panels and cubicles, kitchens and tea points and urinals and WCs. Whether you call it commercial sealant work, mastic application or joint sealing, in Hungerford it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Pub and restaurant kitchens around smaller places like Hungerford work hard on their joints. Smooth, sealed joints at worktops, sinks and wall cladding make cleaning easier, using a food-safe product near food preparation.

Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

What the job involves on each surface

Showers and trays

In staff, hotel and changing-room showers, the tray joint and wall corners take the hardest use. Every joint is stripped, degreased, dried and given a new bead.

Basins and vanity tops

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

Site staff or a sealant specialist?

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

FAQs: Hungerford

Must every washroom in our Hungerford building shut while you work?

Rarely all at once: work is phased so some facilities are always available. We’ll tell you the curing time for the product before we start.

Is a smaller place like Hungerford outside your area?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Can you reseal washrooms in healthcare buildings?

We do. We work to your estates and infection-control requirements and any site permits. The work is phased around patients or residents.

What site paperwork can you supply?

Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards, as many construction sites ask for.

How long do sealant joints last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

How many days will you need on site?

The duration is planned around your programme and the access we’re given. We’ll give you an estimate of time on site when we quote.

What we’re called out for in Hungerford

Mop buckets, trolleys and knocks from users damage joints near the floor at skirting lines, urinal bases and around pans.

Any of the following is a good reason to get the joints checked over:

  • Black mould inside silicone joints that cleaning can’t shift
  • Resealing that didn’t last because the old bead stayed
  • Gaps where vanity tops meet the wall
  • Failed joints along IPS and cubicle panels

Welfare facilities in units on estates such as Hungerford Trading Estate (to the west of Hungerford) have showers, toilets and kitchens with sealant that works hard.

Comparing quotes

  • Will failed sealant be removed rather than covered?
  • What level of public liability insurance do they hold?
  • What site paperwork they can supply
  • Health and safety accreditation such as CHAS

Questions to ask before you appoint anyone

Wet areas in Hungerford’s workplaces

Hungerford lies roughly 62 miles out from central London, within the office belt around the capital. Business park offices have washrooms in daily use by staff, so we work a block of facilities at a time. There are a number of hotels within about 2 miles of Hungerford. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. Rooms are done in turn so most stay available.

For a hall at a building such as Church of St Lawrence, resealing the kitchen and toilets can be fitted between bookings. For a school such as Hungerford Primary School, washroom and kitchen sealant can be renewed around term dates.

Keeping the joints sound

For the best life from the joints:

  • Photograph and log failed joints across the estate
  • Squeegee showers and trays after busy periods
  • Brief cleaning staff to treat joints gently
  • Mention any site permits or estates rules at quote stage

Keep extract fans working and vents clear. A room that stays damp will grow mould on almost anything so report fans that aren’t working to your building services team.

Mould in a joint spreads along the bead and into nearby grout, and complaints follow. Replacing it early keeps the job to a reseal.

How a job runs

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes half a day to a day per washroom, depending on the number of fittings, and we clear our waste as we work. For a site in Hungerford, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. The phasing is agreed so there are always facilities open.
  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.

Getting the site ready

  • Let building users know which areas are affected
  • For older buildings, check the asbestos register before work
  • Send your site hours and access windows
