Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

On site: what to expect

We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact. For work around Mottisfont, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.

  1. We agree which washrooms close and when.
  2. Anything behind the joints that needs another trade is flagged.
  3. Failed sealant and residue are stripped out.
  4. We reseal with the grade suited to each area.
  5. We give you a reopening time for every room.

Preparing the site

  • Let us know about inductions and permits
  • Tell staff and tenants when we’ll be in

About our washroom sealing in Mottisfont

From one staff toilet in Mottisfont to washrooms across a whole estate, we work the same way: send details, get a fixed quote, we seal, guaranteed. Photos and a rough count of basins, urinals, showers and cubicles help us give a quick quote and a site visit is an option. If you have sealant stained black around basins and showers and washrooms that look worn because of the sealant, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, in Mottisfont it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Halls and community buildings near places like Mottisfont are used by different groups through the week, and their toilets and kitchens show it. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

FAQs: Mottisfont

Would you work within a site like Romsey Community Hospital?

Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is a smaller place like Mottisfont outside your area?

No. Places such as Mottisfont are covered as much as the big towns. London and every South East county are within our area. 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.

Does weather matter for sealant work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

What’s the quickest route to a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.

Do you phase washroom resealing?

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

Building owners, agents and FMs in Mottisfont

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so the building keeps working while we do.

Quoting for work in Mottisfont

There’s no standard rate for sealant work, because every site is different. What we take into account:

  • Joint width, depth and condition
  • Working within restricted access windows
  • The total length or number of joints
  • How accessible the joints are

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

What to include in your enquiry

Diagnosis starts before we arrive. Let us know:

  • Any specification or named product
  • How the joints are reached, and at what height
  • What the building is and how it’s used
  • The site address and postcode

Need a figure for a tender or a budget? We will quote against your scope and drawings that you can work with. For a chat about it beforehand, call the office on 01277 525 020 or email us.

General trades versus a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.

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. Each bead is stripped, the joint dried and new sealant laid.

Basins and vanity tops

Basin joints get wet every time someone washes their hands, so the wall joint and bowl surrounds tend to fail before anything else. We remove the old bead and lay a fresh one of sanitary silicone.

At about 70 miles from central London, Mottisfont is within reach of the capital. Business park offices have washrooms in daily use by staff, so we work a block of facilities at a time.

Office toilets at parks like Home Farm Business Centre, 2.2 miles to the west of Mottisfont, take steady weekday use, and mouldy silicone soon shows.

When to call us in Mottisfont

Panels and vanity units move slightly in use, and shower trays shift under foot. A bead that can’t cope with the movement splits along one edge.

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

  • Failed joints along IPS and cubicle panels
  • Failed sealant in a tea point or staff kitchen
  • Failed sealant behind washroom basins
  • Sealant stained black around basins and showers

Where you are responsible for a hall attached to a building such as Church of St Andrew, its kitchen and toilets need sealant that stays cleanable.
