Toilets, showers and kitchens around Portmore

The sea is no more than about 1 mile from Portmore, and coastal hotels, guest houses and holiday sites tend to fill up in the busy months. Bathrooms turned round daily in the busy months need sound, cleanable joints, and the quieter months are the natural time to reseal. A number of hotels sit less than 2 miles from Portmore. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. We work a handful of rooms at a time, so the hotel keeps letting the rest.

Staff changing rooms and patient toilets at places like Lymington New Forest Hospital, 1 mile to the south-west of Portmore, need cleanable, sound silicone. Schools such as Southlands School have toilets, changing rooms and kitchens that are best resealed in the holidays. Hotels such as Macdonald Elmers Court Hotel & Resort, 1.2 miles south of Portmore, have en suite bathrooms where tired silicone at the bath, tray and basin is replaced room by room.

Portmore is about 2 miles north-east of Lymington, in Hampshire. Our applicators travel to Portmore for work on washrooms and wet areas. Across Hampshire, 723 places are covered, including Portmore. Our Southampton page has more on work in that area.

Washroom sealing for commercial buildings in Portmore

Since 2005 we have resealed commercial washrooms for facilities teams, contractors and building owners. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We are fully insured. Every resealed washroom carries our 12-month guarantee. We work on accessible toilets and changing rooms, IPS panels and cubicles and urinals and WCs, and the usual reasons a site gets in touch are users noticing mouldy joints and mould spotting along silicone joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Portmore, preparation and product choice get the time they need.

Farm shops, cafés and venues in converted rural buildings around places like Portmore have busy toilets and kitchens. Tell us your opening times and quiet periods and we’ll plan around them.

We stand by our work with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

General trades versus a specialist

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

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. For that reason, many FMs and contractors use a sealant specialist from the outset.

Our process

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Rural sites near Portmore may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. Every room is surveyed and the failed joints listed.
  2. You get a fixed quote with the phasing plan.
  3. Old sealant is removed completely and the faces cleaned.
  4. Joints are degreased and dried.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Each area is handed back when ready.

Preparing the site

  • Clear stock, furniture or equipment away from the joints
  • For older buildings, check the asbestos register before work
  • Let building users know which areas are affected

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, call 01277 525 020 or email a schedule or drawings.

Quoting for work in Portmore

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • Induction, permit and paperwork requirements
  • How accessible the joints are
  • Specialist products, such as fire-rated or hygienic sealants
  • The total length or number of joints

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Before you send an enquiry

Whether it’s one area or a whole building, the same details help:

  • The type of building and who uses it
  • Specification clauses that apply
  • Asbestos survey details if the building is older
  • When you need the work done

Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. To get it moving, call 01277 525 020 or email a schedule or drawings.

Common questions from Portmore clients

Is a smaller place like Portmore outside your area?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Is hospital work, at somewhere like Lymington New Forest Hospital, something you do?

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.

How do we ask for a quote?

The quote form is the simplest route, though you can also ring 01277 525 020 or email us. Photos, drawings or a joint schedule help us quote quickly.

Do you take on multi-site work?

Yes. Several buildings can share a single quote, and you deal with one contact throughout.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

How do you choose the sealant?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Is it possible to just clean mouldy silicone?

Not for long. Mould grows into the sealant itself, so it comes back however often it’s cleaned. Replacing the bead is the lasting answer.

Looking after the joints

A few simple habits keep the new joints working:

  • Act on the first split you see at a shower tray
  • Leave signs up until the cure time is over
  • Note failing joints building by building
  • Add sealant joints to planned maintenance checks

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.

A split joint at a shower tray can leak for a long time before anyone sees it. By then, other trades may be needed as well, so reseal when you first spot a split.

When it isn’t the sealant

Being straight saves everyone time. New sealant won’t cure:

  • A dripping waste or valve behind a panel
  • Swollen or delaminated boards behind panels or vanity tops
  • Water escaping beneath the floor rather than through a joint

If you are not sure, just ring 01277 525 020 or email us and we will give you a straight answer.

What we seal

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

Why deal with it now?

Waiting for a holiday closure can leave failing joints in place for a long time. With phasing, the work can go ahead while most facilities stay open. For buildings around smaller places like Portmore, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.
