Washroom sealing near Horsleys Green

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

Surface by surface

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.

IPS and cubicle panels

Panels flex slightly in use so the bead needs to cope with it. We check fixings before sealing.

Washroom sealing for commercial buildings in Horsleys Green

Facilities managers, contractors and building owners have used us for washroom sealing for over 20 years. We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. We are fully insured. Our workmanship is guaranteed for 12 months. We work on urinals and WCs, vanity units and basins and showers, trays and wet room floors, and what we’re called in for most is failed sealant in a tea point or staff kitchen and sealant stained black around basins and showers. For commercial sealant work in Horsleys Green, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Community buildings around smaller places like Horsleys Green have kitchens and toilets used by many people. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.

We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Your questions answered

Can you take on a job at a hospital such as Wycombe Hospital?

Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is Horsleys Green too far out for you?

No. Small places get the same service as large ones. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Do you offer coloured sealant?

It depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators, which many sites require.

When can showers be used after new sealant?

The silicone needs time to cure before water reaches it. Phasing is planned with the cure time in mind so there are always rooms open.

When is resealing likely to be due?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Do you need to see the site first?

That depends on the size and complexity of the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.

When to call us in Horsleys Green

Low-level joints get hit by mop buckets, cleaning trolleys and feet, especially at floor edges and around urinals and WC pans.

Any of the following is a good reason to get the joints checked over:

  • Sealant lifting along a tray edge
  • Gaps where vanity tops meet the wall
  • Sealant laid over old silicone and now peeling
  • Black mould inside silicone joints that cleaning can’t shift

For a school such as The Mary Towerton School At Studley Green, washroom and kitchen sealant can be renewed around term dates.

Questions to ask before you book

  • Who will actually carry out the work
  • Do they follow the manufacturer’s priming guidance?
  • Proof of insurance
  • Which product they’ll use, and why it suits the joint

How to choose a sealant contractor

Should maintenance staff do it?

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

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Our process

Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Smaller jobs around Horsleys Green can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.

  1. We agree which washrooms close and when.
  2. Leaks, loose panels or damp are pointed out first.
  3. Old sealant is stripped and the faces prepared.
  4. We reseal with the grade suited to each area.
  5. We give you a reopening time for every room.

Getting the site ready

  • Explain the parking and delivery arrangements
  • Point out any areas we must not close
  • Tell staff and tenants when we will be in

Ask for a quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.

Advice

When it isn’t the sealant

Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:

  • Water escaping beneath the floor rather than through a joint
  • A room that stays damp because ventilation isn’t working
  • Panel boards already damaged by water

If in doubt, call the office on 01277 525 020 or email the details over and we will say what we think.

Where we work in Horsleys Green

  • Kitchens and tea points
  • Urinals and WCs
  • Showers, trays and wet room floors
