Quoting for work in Shirrell Heath

What shapes the price:

  • Quantities, in metres or numbers
  • Whether old sealant has to be cut out first

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Before you send an enquiry

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • Anything awkward about access or site hours

  • Your programme or deadline
  • A wide shot and a close-up of the area

Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, ring 01277 525 020 or use the quote form.

How we handle washroom sealing in Shirrell Heath

Closing all the facilities in a building isn’t an option. Work is phased by room or by section, so staff, guests or pupils always have somewhere to go. Give us your site hours and access windows and the phasing is planned around them. Most enquiries involve mould spotting along silicone joints and failed joints along IPS and cubicle panels, across vanity units and basins, IPS panels and cubicles and urinals and WCs. Facilities teams, main contractors and managing agents in Shirrell Heath tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

In and around smaller places like Shirrell Heath, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

A 12-month guarantee applies to all our work in Hampshire. If an installation problem shows up, give us a call on 01277 525 020 or email us and we’ll arrange a return visit.

When to bring in a specialist

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Questions we are asked in Shirrell Heath

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

Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is Shirrell Heath too small for you to travel to?

No. Small places get the same service as large ones. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Which sealant will you use?

The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

What guarantee comes with washroom resealing?

A 12-month guarantee covers the work. It applies to our workmanship, not to plumbing leaks or damp from poor ventilation.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and we will price the work to it, flagging anything that needs clarifying.

Can the sealant be colour-matched?

That depends on the product specified. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.

Will all the toilets be closed at once?

Only the area we are working in is closed. Each room reopens after the sealant’s cure time and we start the next.

Surface by surface

Changing rooms and gyms

Gym and leisure changing rooms see showers running most of the day so sealant there works very hard. Anti-mould sanitary silicone is the standard choice.

Basins and vanity tops

Natural stone tops can be marked by acetoxy silicone and we choose a neutral-cure grade for them.

Common problems we fix in Shirrell Heath

We often find acrylic caulk or general-purpose sealant in joints that should have sanitary silicone. They aren’t made for constant wetting and they discolour and fail early.

Site and facilities staff are often the first to spot these:

  • Urinal joints that look unhygienic
  • Open joints along basins and vanity units
  • Stained or open joints at kitchen sinks and worktops
  • Failed joints along IPS and cubicle panels

Office washrooms on sites such as Waltham Business Park, 1 mile to the north of Shirrell Heath, are in use all working day, so resealing is phased to keep some open.

What your quote should include

  • Who will actually carry out the work
  • What site paperwork they can supply
  • How joint depth will be controlled
  • How long is the guarantee, and what does it include?

Maintenance after handover

After handover, these steps help:

  • Include joints in routine washroom inspections
  • Make sure washroom ventilation is running
  • Keep a record of which washrooms need attention
  • Keep washrooms out of use until we say the sealant has cured

Any failure in our workmanship within the 12-month guarantee is ours to put right. After that, a routine look catches failing joints early.

Leaks through tray and wet-floor joints can go unseen until a ceiling marks below. By then, other trades may be needed as well, so reseal when you first spot a split.

Diagnose, treat, sign off

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Jobs in and around smaller places like Shirrell Heath are normally planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. We inspect each washroom and record the joints to be resealed.
  2. You get a fixed quote with the phasing plan.
  3. The whole of the old bead is removed.
  4. Each joint is cleaned and left dry.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Each area is handed back when ready.

Preparing the site

  • Explain the parking and delivery arrangements
  • Have the specification and drawings to hand
  • Send your site hours and access windows
