Washroom sealing for Alphamstone sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Our process

Site rules come first: signing in, inductions and any permit to work. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact. If others near Alphamstone need work, visits can be combined. You will have a fixed quote before work starts.

  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. Rooms reopen after the cure time.

Before we start on site

  • Agree which areas must stay open
  • Confirm the product named in the specification
  • Share your working hours and any access restrictions

Request a quote

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

Washroom sealing in Alphamstone, done properly

In a busy washroom, the sealant typically gives up long before the tiles or fittings. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning and mould that roots into it can’t be cleaned away. We strip it out and lay new anti-mould sanitary silicone. Most enquiries involve sealant lifting along a tray edge and gaps where vanity tops meet the wall, across urinals and WCs, kitchens and tea points and vanity units and basins. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Alphamstone, preparation and product choice get the time they need.

Farm shops, cafés and venues in converted rural buildings around places like Alphamstone have busy toilets and kitchens. We plan the work around bookings and opening times.

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

What sets the cost

What shapes the price:

  • Location, for remote and island sites
  • The site’s rules and procedures
  • How accessible the joints are
  • The size and state of each joint

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

What we need to price the job

Diagnosis starts before we arrive. Tell us:

  • Drawings or a marked-up plan, if available
  • The site address and postcode
  • Asbestos survey details if the building is older
  • The type of building and who uses it

To get a fixed quote, give us a call on 01277 525 020 or send photos by email with the site address and an outline of the work. Our quote form is another easy route.

Doing it in-house

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

FAQs: Alphamstone

Do you take on work at healthcare sites like Halstead Hospital?

Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.

Is Alphamstone too far out for you?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Will you quote for a small job?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

Can you send site paperwork?

Requirements differ from site to site, so tell us what you need and we’ll confirm it when we quote.

Which sealant will you use?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Does the weather affect the work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

Signs you need washroom sealing in Alphamstone

Sometimes the sealant fails because something behind it is moving or wet: loose fixings, a dripping trap or damp in the wall. We check for that first and tell you if another trade is needed.

Clients typically get in touch after noticing one or more of the following:

  • Gaps where vanity tops meet the wall
  • Black mould inside silicone joints that cleaning can’t shift
  • Users noticing mouldy joints
  • Urinal joints that look unhygienic

For a hall at a building such as Parish Church of St Barnabas, resealing the kitchen and toilets can be fitted between bookings.

What to look for in a quote

  • Can the work be phased to keep areas open?
  • Is the sealant right for the movement and the substrate?
  • Do they follow the manufacturer’s priming guidance?
  • Will CSCS-carded applicators be on site?

Choosing a commercial sealant contractor

When something else is needed

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:

  • Hollow tiles or loose panels behind the joint
  • Water escaping beneath the floor rather than through a joint
  • Mould caused by poor ventilation, which will return until the extract is fixed

If you’re not sure, just call 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.

Joints and surfaces we work on

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

Different surfaces, different methods

Urinals and WC pans

Pan and urinal joints face constant cleaning and splashing. Once they discolour or split, they hold odours and make the room look neglected.

Wet-room floors and floor-to-wall joints

Sealant at a wet-room floor edge is not a substitute for the waterproofing underneath and point it out if water appears to rise from below.
