Micheldever: questions and answers

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

Not all at once. We take one block of facilities at a time. Sanitary silicone needs time to cure before the area is used, and we’ll tell you how long for the product used.

Is Micheldever off your patch?

Not at all. Micheldever is within our area. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators, as many construction sites ask for.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

What will the job cost?

Each job is quoted on its own details. For yours, speak to us on 01277 525 020 or email us.

How long before the toilets can reopen?

Cure times vary by product and temperature. You will get a reopening time for each area before we leave it.

What happens if old sealant might contain asbestos?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

Keeping Micheldever washrooms open while we work

Micheldever lies roughly 56 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.

For a hall at a building such as Church of St Mary, resealing the kitchen and toilets can be fitted between bookings. Schools such as Micheldever CofE Primary School have toilets, changing rooms and kitchens that are best resealed in the holidays.

Micheldever is about 7 miles north of Winchester, in Hampshire. Micheldever sits inside our coverage and the rest of Hampshire, and jobs here get the same fixed quote and 12-month guarantee as anywhere else.

Doing it in-house

Redoing a failed joint normally 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.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Diagnose, treat, sign off

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Jobs in and around smaller places like Micheldever are normally planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. We agree which washrooms close and when.
  2. Leaks, loose panels or damp are pointed out first.
  3. Old sealant is stripped and the faces prepared.
  4. We reseal with the grade suited to each area.
  5. We give you a reopening time for every room.

Before we start on site

  • Send any specification or drawings in advance

Advice

Owners, agents and contractors

Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Micheldever. One quote can cover more than one site, which keeps the paperwork simple.

For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

Maintenance after handover

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Keep extract fans working and vents clear
  • Leave signs up until the cure time is over
  • Include joints in routine washroom inspections
  • Brief cleaning staff to treat joints gently

If a joint we sealed fails within 12 months, tell us and we’ll look at it. 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.

What happens if it’s left?

Sealing on top of old silicone saves nothing. Silicone won’t grip silicone, so it lifts and holds moisture underneath. Full removal and proper cleaning is what makes the new joint last. Older rural buildings around Micheldever move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

Honest limits

We check first that sealant really is the fix. It isn’t the answer for:

  • Panel boards already damaged by water
  • A room that stays damp because ventilation isn’t working
  • Water escaping beneath the floor rather than through a joint

If in doubt, give us a call on 01277 525 020 or email drawings and photos and we will say what we think.
