How we handle washroom sealing in Higham

Not every silicone belongs in a washroom. Sanitary grades carry anti-mould additives, and neutral-cure versions avoid the damage acetoxy types can do to some metals, stone and mirror backings. In food areas, hygienic or food-safe sealants are used where food contact is possible. If you have mould spotting along silicone joints and kitchen worktop joints that can’t be kept clean, we can help, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Higham is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

In and around smaller places like Higham, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

General trades versus a specialist

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Signs you need washroom sealing in Higham

Low-level joints get hit by mop buckets, cleaning trolleys and feet at skirting lines, urinal bases and around pans.

Look out for the following:

  • Gaps where vanity tops meet the wall
  • Washrooms that look worn because of the sealant
  • Split or peeling sealant at shower trays
  • Stained sealant around pans and urinals

For a school such as Stratford St Mary Primary School, washroom and kitchen sealant can be renewed around term dates.

Questions to ask before you book

  • Their pre-qualification and accreditations
  • Their approach to joint depth and backing
  • Which product they’ll use, and why it suits the joint
  • How long is the guarantee, and what does it include?

Our contractor checklist

What sets the cost

Your fixed quote is built from the real scope. It allows for:

  • Site requirements such as inductions and permits
  • Whether the work must be split into stages
  • Distance, for remote addresses
  • Whether old sealant has to be cut out first

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

What we need to price the job

Diagnosis starts before we arrive. Tell us:

  • Anything awkward about access or site hours
  • Clear photographs of the problem areas
  • Rough lengths or quantities, or drawings if you have them
  • The asbestos register, for older buildings

Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to call the office on 01277 525 020 or send photos by email.

Diagnose, treat, sign off

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes half a day to a day per washroom, depending on the number of fittings, and our waste is bagged and taken away as we go. For work around Higham, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. Every room is surveyed and the failed joints listed.
  2. You get a fixed quote with the phasing plan.
  3. Old sealant is removed completely and the faces cleaned.
  4. Joints are degreased and dried.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Each area is handed back when ready.

Getting the site ready

  • Send your site hours and access windows
  • Move anything stored against the joints
  • Arrange parking or a loading space

Staff changing rooms and patient toilets at places like Severalls Hospital (5.2 miles south-west of Higham) need cleanable, sound silicone. Where you are responsible for a hall attached to a building such as Church of St Mary, its kitchen and toilets need sealant that stays cleanable.

Questions about Higham

Is Higham off your patch?

Not at all. Higham is within our area. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.

Does a hotel in Higham need to shut while its sealant is renewed?

Rarely, if ever. We take a few rooms out at a time. Tell us your quiet periods and access windows and we’ll plan around them.

Is any job too small?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

Is it OK to put new silicone on top of the old?

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.

Which silicone is right for commercial washrooms?

An anti-mould sanitary silicone in the majority of cases. We use neutral-cure versions on stone, some metals and near mirrors.

What happens if old sealant might contain asbestos?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

Will cleaning remove black mould from sealant?

Surface cleaning won’t reach mould that has rooted into the bead. We replace the sealant with an anti-mould sanitary grade and check the ventilation isn’t the cause.

Building owners, agents and FMs in Higham

If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

Why it’s worth doing now in Higham

Bleaching black sealant may lighten it for a few days, but the mould is rooted in the silicone and comes back. A full reseal deals with it and your cleaning team stops chasing it. Around Higham, it’s better to renew all the failing joints at once. Send photographs of each area and we will quote for the lot.

The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Why us?

  • Colours chosen to suit frames, cladding or finishes where possible
  • Work carried out by CSCS-carded applicators
  • Colours confirmed for the specified product
  • Sealing commercial buildings since 2005
