About our washroom sealing in Alderholt

You can’t shut every toilet in an office, school or hotel at once. Work is phased by room or by section, so there are always facilities in use. Tell us your site hours and access windows and we will plan around them. We work on showers, trays and wet room floors, urinals and WCs and kitchens and tea points, and the failures we’re asked to look at most are a new bead over an old one coming away and kitchen worktop joints that can’t be kept clean. One point of contact handles commercial sealant work in Alderholt from the first photos to the final walk-round, whether it’s one building or several.

In a smaller place such as Alderholt, commercial washrooms tend to be in schools, pubs, cafés, surgeries, care homes and sports clubs. They don’t need a big crew, but they do need old sealant fully cut out before anti-mould silicone goes on.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

What happens if it’s left?

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. Small buildings around Alderholt suffer from failed joints as much as large ones. Catching it early means a reseal rather than repairs.

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.

Cost factors for washrooms and wet areas

These are the things that shape the price:

  • How much existing material needs removing
  • Travel to remote or island sites
  • The total length or number of joints
  • The site’s rules and procedures

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

Before you send an enquiry

For an accurate fixed quote, we need to understand the site. Send us:

  • Rough lengths or quantities, or drawings if you have them
  • How the joints are reached, and at what height
  • When you need the work done
  • The asbestos register, for older buildings

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.

Questions we are asked in Alderholt

Is a hospital such as Fordingbridge Hospital somewhere you can work?

Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.

Do we have to close all our washrooms in Alderholt for resealing?

Normally only some of them, for a short time. We work in phases so other facilities stay open. Sanitary silicone needs time to cure before the area is used, and we’ll tell you how long for the product used.

Do you need to remove the old sealant?

We always remove it. Fresh silicone can’t key to an old bead so a bead over the top fails quickly.

How much does the work cost?

We don’t publish prices, because every site is different. Send photos or drawings and we’ll price it at a fixed figure.

Can the sealant be colour-matched?

It depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

Do you take on multi-site work?

Yes. A group of buildings can go on one quote, and you deal with one contact throughout.

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. We don’t remove asbestos-containing materials.

Site staff or a sealant specialist?

Putting right a botched joint often costs more than sealing it well at the start, 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.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Busy facilities in and around Alderholt

On a healthcare site such as Fordingbridge Hospital, which lies north-east of Alderholt, washroom work starts with the infection-control team’s sign-off. Where you’re responsible for a hall attached to a building such as Church of St James, its kitchen and toilets need sealant that stays cleanable. For a school such as St James' Church of England First School, washroom and kitchen sealant can be renewed around term dates.

How a job runs

Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. For a site in Alderholt, we plan so the whole job is done in one go where possible. Clear photos and measurements help us bring the right products.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. We agree which rooms close and when, so users always have somewhere to go.
  3. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. We clean and dry every surface so the new sealant can grip.
  5. New sanitary silicone with anti-mould additives goes in and is tooled neat.
  6. Rooms reopen after the product’s cure time, and we move to the next.

What we need from you

  • Confirm the product named in the specification
  • Clear stock, furniture or equipment away from the joints
  • Share your working hours and any access restrictions

What the job involves on each surface

Healthcare and care settings

Assisted bathrooms and accessible toilets get heavy use, so their joints often need renewing sooner.

Urinals and WC pans

Joints around urinals and WC pans take splashes, cleaning chemicals and knocks. Stained or split joints here trap smells and make the room look neglected.

Work for main contractors and building owners

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

If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.
