On site: what to expect

Before we leave any area, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. For a building around Mullenspond, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. We inspect each washroom and record the joints to be resealed.
  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.

What we need from you

  • Send asbestos survey details if the building is pre-2000
  • Arrange parking or a loading space
  • Tell us which areas need to stay in use

Quotes

What the job involves on each surface

IPS and cubicle panels

A panel that has already swollen won’t be fixed by sealant, and any we come across will be pointed out.

Kitchens and tea points

Kitchen joints need to be smooth and sealed so they can be cleaned properly. Food-safe sealants are used where food may touch the joint.

Honest limits

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Vanity carcasses that have swollen
  • Water from plumbing, not from a joint
  • Fittings that move too much to hold a bead

Not sure which it is? You can give us a call on 01277 525 020 or email drawings and photos and we’ll tell you honestly.

Where we work in Mullenspond

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

Questions about Mullenspond

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

Rarely all at once: work is phased so some facilities are always available. Each area is handed back once the sealant has cured enough to use.

Is a smaller place like Mullenspond outside your area?

Not at all. Mullenspond is within our area. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Which silicone is right for commercial washrooms?

Sanitary silicone with anti-mould additives for most washroom joints. We use neutral-cure versions on stone, some metals and near mirrors.

Can weather delay the job?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Do you guarantee washroom sealing?

A 12-month guarantee covers the work. It covers our workmanship rather than damage, leaks from plumbing or ventilation problems.

Do you hold CHAS accreditation?

Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.

Can the sealant be colour-matched?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.

Work for main contractors and building owners

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

We work for building owners and managing agents 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.

Keeping the joints sound

Keep the joints in good shape with a few simple steps:

  • Report faulty extraction promptly
  • Add sealant joints to planned maintenance checks
  • Clear standing water from shower floors where possible
  • Keep washrooms out of use until we say the sealant has cured

Keep extract fans working and vents clear. Constant damp lets mould take hold even on anti-mould grades so report fans that aren’t working to your building services team.

A few failed joints can be resealed with hardly any disruption. Left, it tends to become a building-wide job and more closures to manage.

Do you need washroom sealing in Mullenspond?

Occasionally a joint keeps failing because of a problem behind it: loose fixings, a dripping trap or damp in the wall. We check for that first and say if it needs a plumber or another trade.

Clients typically get in touch after noticing something like this:

  • Split or peeling sealant at shower trays
  • Washrooms that look worn because of the sealant
  • Discoloured joints around urinals and WC pans
  • Sealant laid over old silicone and now peeling

For a site such as Andover War Memorial Hospital, 3.5 miles to the east of Mullenspond, sanitary joints in clinical areas need sound, cleanable sealant and a careful method.
