Washroom sealing in Elmstone

You can’t shut every toilet in an office, school or hotel at once. Work is phased by room or by section, so there are always facilities in use. Give us your site hours and access windows and the phasing is planned around them. We work on accessible toilets and changing rooms, kitchens and tea points and urinals and WCs, and the failures we’re asked to look at most are failed joints along IPS and cubicle panels and split or peeling sealant at shower trays. Whether you call it commercial sealant work, mastic application or joint sealing, in Elmstone 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 Elmstone still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Sealant that has gone black with mould typically can’t be cleaned, so it is cut out and replaced.

A 12-month guarantee applies to all our work in Kent. Should something we installed fail, ring 01277 525 020 or email a schedule or drawings and we will come back to it.

Owners, agents and contractors

Facilities managers want contractors who arrive with the paperwork sorted. 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’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

Common problems we fix in Elmstone

Decorators’ caulk and general sealants sometimes end up where sanitary silicone belongs. They aren’t made for constant wetting and they discolour and fail early.

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

  • Resealing that didn’t last because the old bead stayed
  • Mould spotting along silicone joints
  • Shower tray joints that have opened up
  • Failed joints along IPS and cubicle panels

Church halls and community buildings, such as those at Elmstone Church, have kitchens and toilets used by many groups, and their sanitary sealant works hard.

Questions to ask before you book

  • Health and safety accreditation such as CHAS
  • Their approach to joint depth and backing
  • How long is the guarantee, and what does it include?
  • Will RAMS and insurance details be available?

Our contractor checklist

General trades versus a specialist

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

What affects the price in Elmstone

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • Whether the work must be split into stages
  • Specialist products, such as fire-rated or hygienic sealants
  • The total length or number of joints
  • How much existing material needs removing

What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote when you are ready.

Details that help us quote

However big the job, these details speed things up:

  • Any dates the work must fit around
  • Access details, including height
  • Rough lengths or quantities, or drawings if you have them
  • The site address and postcode

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

Diagnose, treat, sign off

Diagnose, treat, sign off: every visit follows that pattern. 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. If others near Elmstone need work, visits can be combined, 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.

What we need from you

  • Clear stock, furniture or equipment away from the joints
  • Explain the parking and delivery arrangements
  • Have the specification and drawings to hand

Related advice

Different surfaces, different methods

Changing rooms and gyms

Changing rooms in gyms and leisure centres stay wet and warm so sealant there works very hard. We use anti-mould sanitary silicone throughout.

IPS and cubicle panels

Swollen or delaminated boards need replacing and we will point out any we see.

Questions we are asked in Elmstone

Must every washroom in our Elmstone building shut while you work?

Typically 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.

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

Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

How much does the work cost?

We don’t publish prices, because every site is different. With photos or drawings, we can give you a fixed quote.

What guarantee comes with washroom resealing?

Every job carries our 12-month guarantee. It applies to our workmanship, not to plumbing leaks or damp from poor ventilation.

What sealant do you use in washrooms?

It depends on the joint. Most washroom joints take sanitary silicone while kitchens may need a food-safe grade.

Do you hold CHAS accreditation?

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