Do you need washroom sealing in Egham Hythe?

  • Stained sealant around pans and urinals
  • Users noticing mouldy joints
  • Shower tray joints that have opened up
  • Sealant stained black around basins and showers

Questions to ask before you appoint anyone

How we handle washroom sealing in Egham Hythe

You can’t shut every toilet in an office, school or hotel at once. We phase the work one washroom, one bank of cubicles or one changing room at a time, so staff, guests or pupils always have somewhere to go. Give us your site hours and access windows and the phasing is planned around them. We work on vanity units and basins, showers, trays and wet room floors and accessible toilets and changing rooms, and what we are called in for most is open joints at the base of cubicle panels and resealing that didn’t last because the old bead stayed. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Egham Hythe is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

In and around places like Egham Hythe, hospitality kitchens and toilets see heavy use in busy spells. Smooth, sealed joints at worktops, sinks and wall cladding make cleaning easier, using a food-safe product near food preparation.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Surface by surface

IPS and cubicle panels

Panel systems meet walls, floors and vanity tops at sealed joints. Those joints protect the boards behind from water.

Kitchens and tea points

Kitchen work can be phased around service. Tell us your site hours and access windows and we’ll plan around them.

Maintenance after handover

For the best life from the joints:

  • Add sealant joints to planned maintenance checks
  • Make sure washroom ventilation is running
  • Mention any site permits or estates rules at quote stage
  • Don’t leave an open joint at a basin or tray

Where possible, have shower floors and trays squeegeed after busy periods. Standing water on a joint all day shortens its life.

Mould in a joint spreads along the bead and into nearby grout and users notice. Dealing with it while it’s just the sealant keeps it simple.

Work for main contractors and building owners

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

Questions about Egham Hythe

Will you plan work around the academic year at somewhere like Royal Holloway University?

Yes. We plan campus work around teaching, exams and residence turnarounds. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Is Egham Hythe too small for you to travel to?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

Do you hold CHAS accreditation?

Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

How do I request a quote?

The quote form is the simplest route, though you can also give us a call on 01277 525 020 or email us. Include photographs or drawings if you have them.

Can you clean the mould off instead of resealing?

Normally not. The mould is inside the silicone so cleaning only lightens it for a while. Replacing the bead is the lasting answer.

How soon can a washroom be used after resealing?

That varies with the sealant and the room temperature. Each room gets its own reopening time from us before we leave it.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

On site: what to expect

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. For a job in Egham Hythe, the main thing is a clear picture of the work, so send photos of each area. You will then get a fixed price for the work.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. The phasing is agreed so there are always facilities open.
  3. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. Joints are cleaned, degreased and dried before sealing.
  5. A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
  6. You get a reopening time for every room, with signage left up until then.

Getting the site ready

  • Flag any permit to work we’ll need
  • Point out parking and an unloading spot
  • Share your working hours and any access restrictions

Leave it or put it right?

Gaps and mould in joints give dirt and bacteria somewhere to sit, and in kitchens, clinics and schools that is a real concern. Sound, smooth joints are much easier to keep clean. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.

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