Washroom sealing across Crampmoor

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Questions we’re asked in Crampmoor

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

Yes. We agree rooms and times with the manager and work a few areas at a time. Any site rules, from signing in to infection control, are agreed before we start.

Is hospital work, at somewhere like Romsey Hospital, something you do?

Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.

Do you need to remove the old sealant?

The failed bead is always removed. Fresh silicone can’t key to an old bead, so sealing over it soon peels.

Do you cover Crampmoor?

Yes. We cover Crampmoor and the rest of Hampshire, within our coverage of Greater London, South East England and Scotland. To discuss a job, speak to us on 01277 525 020 or email us.

Are you fully insured?

Yes. We are fully insured, and the certificate can go with your quote.

Is any job too small?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Does weather matter for sealant work?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

How we handle washroom sealing in Crampmoor

We reseal washrooms and wet areas in offices, hotels, schools, universities, gyms, healthcare buildings and care homes, along with staff kitchens and tea points. Product and method follow how hard each area is used and cleaned. If you have black mould inside silicone joints that cleaning can’t shift and stained sealant around pans and urinals, we can help, whatever the surface. A single leaking joint is often how a building in Crampmoor 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.

Rural businesses near smaller places such as Crampmoor, from cafés to event venues, rely on washrooms and kitchens that stay clean. We plan the work around bookings and opening times.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Honest limits

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

  • Water escaping beneath the floor rather than through a joint
  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • A room that stays damp because ventilation isn’t working

Not sure which it is? You can speak to us on 01277 525 020 or use the quote form and we will tell you honestly.

What we seal

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

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.

Urinals and WC pans

Joints around urinals and WC pans take splashes, cleaning chemicals and knocks. Once they discolour or split, they hold odours and look unhygienic.

Should maintenance staff do it?

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Washroom sealing around Crampmoor: what changes locally

Crampmoor has three care or nursing homes no more than 2 miles away. In a care setting, a mouldy or lifting joint in a wet room is a hygiene issue as much as a cosmetic one. Rooms are done a few at a time at times agreed with the home. Crampmoor is about 68 miles from central London, in a commuter belt where offices and business parks are common. Office toilets in the commuter belt are in use from first arrivals to last departures, so we phase work to keep some facilities open.

Office washrooms on sites such as Sleepy Hollow Business Park, 0.8 miles north-east of Crampmoor, are in use all working day, so resealing is phased to keep some open. For a site such as Romsey Hospital, which lies south-west of Crampmoor, sanitary joints in clinical areas need sound, cleanable sealant and a careful method. Where you’re responsible for a hall attached to a building such as St Swithun's Church, its kitchen and toilets need sealant that stays cleanable.

Crampmoor is about 1 mile north-east of Romsey, in Hampshire. We cover Crampmoor and the rest of Hampshire, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Our Hampshire coverage takes in 723 places, from busy centres to rural villages. There’s a separate page for Southampton, about 6 miles away.
