About our washroom sealing in Kingston Blount

Since 2005 we have resealed commercial washrooms for facilities teams, contractors and building owners. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We are fully insured. Our workmanship is guaranteed for 12 months. We work on showers, trays and wet room floors, accessible toilets and changing rooms and vanity units and basins, and the failures we are asked to look at most are failed sealant in a tea point or staff kitchen and users noticing mouldy joints. Most enquiries from Kingston Blount start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Halls and community buildings near places like Kingston Blount are used by different groups through the week, and their toilets and kitchens show it. Resealing sinks, worktops and WCs with anti-mould silicone keeps them clean and watertight.

Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Why it’s worth doing now in Kingston Blount

When a washroom looks worn, a refit isn’t the only answer. Where tiles, panels and fittings are sound, new sealant may be enough to put it right while bigger works are planned. Around Kingston Blount, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote when you’re ready.

Why us?

  • Colours confirmed for the specified product
  • Constructionline member for supplier checks
  • 12 months’ guarantee on every job
  • Joints cleaned back to sound surfaces

Take a look at how commercial sealant jobs are priced and our accreditations.

When it isn’t the sealant

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Fittings that move too much to hold a bead
  • Failed tanking beneath a wet-room floor or behind tiles
  • A room that stays damp because ventilation isn’t working

If you’re not sure, just call the office on 01277 525 020 or email the details over and we’ll give you a straight answer before you book.

What we seal

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

What sets the cost

Before we quote, we look at:

  • Backing rod, priming and other preparation
  • The total length or number of joints
  • How accessible the joints are
  • Induction, permit and paperwork requirements

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Sending details for a quote

It doesn’t need to be a full survey. These details are enough to start:

  • The site address and postcode
  • The asbestos register, for older buildings
  • Access details, including height
  • A wide shot and a close-up of the area

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

When to call us in Kingston Blount

Much of the failed sealant we remove was applied over old silicone or residue. New silicone won’t grip the old, so it soon lets go.

It’s worth sending us details if you spot any of the following:

  • Sealant lifting along a tray edge
  • Failed joints along IPS and cubicle panels
  • Failed sealant in a tea point or staff kitchen
  • Complaints from staff, guests or users about tired washrooms

Pupil toilets at schools like Aston Rowant Church of England Primary School take heavy daily use, and the holidays give the window to reseal.

Comparing quotes

  • How long is the guarantee, and what does it include?
  • Is the sealant right for the movement and the substrate?
  • Their approach to joint depth and backing
  • Will RAMS and insurance details be available?

Kingston Blount: questions and answers

Is a smaller place like Kingston Blount outside your area?

No. Places such as Kingston Blount are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Do we have to close all our washrooms in Kingston Blount for resealing?

Usually only some of them, for a short time. We work in phases so other facilities stay open. We will tell you the curing time for the product before we start.

Do you need to remove the old sealant?

The whole of the old bead is removed and the surfaces cleaned first. It’s the difference between a joint that lasts and one that peels.

How do you choose the sealant?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Will your applicators have CSCS cards?

Yes. Our applicators hold CSCS cards.

Can you clean the mould off instead of resealing?

Cleaning may lighten it, but the mould returns. New anti-mould sanitary silicone is the treatment and check the ventilation isn’t the cause.

Is colour matching possible?

That depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

Surface by surface

Changing rooms and gyms

Showers, floor edges and vanity units in changing rooms all need sound sealant and we look at them as one job.

Urinals and WC pans

Joints around urinals and WC pans take splashes, cleaning chemicals and knocks. Once they discolour or split, they hold odours and look unhygienic.

Our process

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Jobs in and around smaller places like Kingston Blount are usually planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. First, the phasing is agreed so facilities stay open.
  2. Leaks, loose panels or damp are pointed out first.
  3. Old sealant is stripped and the faces prepared.
  4. The right sanitary or food-safe sealant is applied.
  5. We give you a reopening time for every room.

Getting the site ready

  • Point out parking and an unloading spot
  • Point out any areas we must not close
  • Tell us what induction or permit system the site runs
