FAQs: Steventon End

Is Steventon End too small for you to travel to?

No. Places such as Steventon End are covered as much as the big 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.

Is hospital work, at somewhere like Saffron Walden Community Hospital, something you do?

Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Do you phase washroom resealing?

We phase it so there are always facilities open. One washroom, one bank of cubicles or one changing room is done at a time around your site hours and access windows.

Do you need to remove the old sealant?

The whole of the old bead is removed and the surfaces cleaned first. That’s what makes the new joint last.

Do you have public liability insurance?

Yes. We’re fully insured, including public liability cover.

Do you work to architects’ specifications?

Yes. Send it with your enquiry, and the quote will be based on it.

What site paperwork can you supply?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.

Washroom sealing in Steventon End

When mould has spotted a silicone joint, more cleaning won’t remove it. The growth is inside the sealant so it returns whatever the cleaning regime. Only replacement gets rid of it for good. If you have complaints from staff, guests or users about tired washrooms and split or peeling sealant at shower trays, we can put it right, on showers, trays and wet room floors, vanity units and basins and urinals and WCs alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Steventon End is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Community buildings around smaller places like Steventon End have kitchens and toilets used by many people. Resealing sinks, worktops and WCs with anti-mould silicone keeps them clean and watertight.

Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

How the quote is worked out

Quotes vary with the job. Expect it to depend on:

  • How accessible the joints are
  • Removal of failed or old sealant
  • Site requirements such as inductions and permits
  • Joint width, depth and condition

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

Sending details for a quote

A few photographs plus some basic facts will normally do. It helps to include:

  • When you need the work done
  • Specification clauses that apply
  • Where the site is, with the postcode
  • Photos of the joints, close up and from further back

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to ring 01277 525 020 or send photos by email with what you know.

When to call us in Steventon End

Commercial cleaning is harder on sealant than everyday use. Strong chemicals, scourers and jet washing roughen, discolour or lift a bead so grime sticks to the damaged surface.

Common reasons buildings call us in:

  • Sealant laid over old silicone and now peeling
  • Shower tray joints that have opened up
  • Stained sealant around pans and urinals
  • Open joints at the base of cubicle panels

On a healthcare site such as Saffron Walden Community Hospital, which lies south-west of Steventon End, washroom work starts with the infection-control team’s sign-off.

What your quote should include

  • How the existing material will be dealt with
  • Proof of insurance
  • Their pre-qualification and accreditations
  • How joint depth will be controlled

Advice

Different surfaces, different methods

Basins and vanity tops

Basin joints get wet every time someone washes their hands, so the joint to the wall and around each bowl fails early. They are resealed with anti-mould sanitary silicone.

Showers and trays

Shower trays move under foot and are wet all day. Tray joints are where many washroom leaks start.

What sealant work can’t fix

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Condensation from failed extract fans
  • Loose panels, vanity units or tiles, which need fixing first
  • Swollen or delaminated boards behind panels or vanity tops

Not sure which it is? You can phone 01277 525 020 or email drawings and photos and we’ll tell you honestly.

Where we work in Steventon End

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

Why act early in Steventon End

Waiting for a holiday closure can leave failing joints in place for a long time. Phasing lets it happen now, with facilities kept in use. Around Steventon End, it’s better to renew all the failing joints at once. Send photographs of each area and we will quote for the lot.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.
