Common problems we fix in Stratfield Mortimer

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:

  • Mould spotting along silicone joints
  • Users noticing mouldy joints
  • Discoloured joints around urinals and WC pans
  • A new bead over an old one coming away

For a hall at a building such as Saint John The Evangelist, resealing the kitchen and toilets can be fitted between bookings.

Questions to ask before you book

  • Who will actually carry out the work
  • Which product they’ll use, and why it suits the joint
  • How they handle RAMS and site documents
  • How long is the guarantee, and what does it include?

Washroom sealing in Stratfield Mortimer, done properly

We reseal washrooms and wet areas in offices, hotels, schools, universities, gyms, healthcare buildings and care homes, along with staff kitchens and tea points. The products and the method are chosen for how heavily each space is used. We work on kitchens and tea points, showers, trays and wet room floors and accessible toilets and changing rooms, and the usual reasons a site gets in touch are open joints along basins and vanity units and stained or open joints at kitchen sinks and worktops. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Stratfield Mortimer it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Smaller places such as Stratfield Mortimer still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Sealant that has gone black with mould normally can’t be cleaned, so it is cut out and replaced.

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

Your questions answered

Will all the washrooms in our Stratfield Mortimer building be closed at once?

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.

What paperwork can you provide for a job in Stratfield Mortimer?

We’ll confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We are CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.

What will the job cost?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.

Is there a guarantee on the work?

There is a 12-month guarantee on our workmanship backed by public liability insurance.

Do you need to see the site first?

It depends on the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.

When is resealing likely to be due?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Are you CHAS accredited?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

On site: what to expect

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before the next one 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. Joints are degreased and dried.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Each area is handed back when ready.

What we need from you

  • Let building users know which areas are affected
  • Send any specification or drawings in advance
  • For older buildings, check the asbestos register before work

Why it’s worth doing now in Stratfield Mortimer

Running fresh silicone along a failed bead hides the problem briefly. It doesn’t bond, so it peels and traps dirt behind it. Cutting out completely and cleaning back takes a little longer and lasts. Around Stratfield Mortimer, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we will quote for the lot.

We don’t publish prices, since every building and every scope is different. Call for a quote and we will price your job on its own details.

  • Sealing commercial buildings since 2005

Surface by surface

Showers and trays

If a tray moves too much or is cracked, it needs attention first, and we’ll say so before resealing.

Basins and vanity tops

A failed joint along a vanity unit lets water into the carcass. Prompt resealing keeps the unit sound.

Keeping the joints sound

For the best life from the joints:

  • Share your site rules when you send details
  • Don’t leave trays and floors sitting wet
  • Note failing joints building by building
  • Make sure washroom ventilation is running

Ask your cleaning team to use gentle products and soft cloths on sealant. Strong acids, solvents and scourers wear the surface and give mould a start.

Small numbers of failed joints are quick to phase in. Left, it tends to become a building-wide job and more closures to manage.

Doing it in-house

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
