Washroom sealing in Frithend, done properly

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. There is public liability insurance behind every job. Every resealed washroom carries our 12-month guarantee. If you’re dealing with gaps where vanity tops meet the wall and a new bead over an old one coming away, we can put it right. Looking for mastic applicators who cover Frithend? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

Smaller places such as Frithend still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Cost factors for washrooms and wet areas

There’s no standard rate for sealant work, because every site is different. What we look at:

  • Whether the work must be split into stages
  • Access and working height
  • The size and state of each joint
  • Induction, permit and paperwork requirements

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Sending details for a quote

Whether it’s one area or a whole building, these details speed things up:

  • The site address and postcode
  • Anything awkward about access or site hours
  • A wide shot and a close-up of the area
  • Drawings or a marked-up plan, if available

Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to call 01277 525 020 or use the quote form.

How the job changes by surface

IPS and cubicle panels

Panel systems meet walls, floors and vanity tops at sealed joints. They stop water reaching the panel boards.

Urinals and WC pans

The joint between a pan and the floor is easy to overlook. We include them in the survey.

Questions we are asked in Frithend

Do you take on work at healthcare sites like Chase Community Hospital?

Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is Frithend too small for you to travel to?

No. Small places get the same service as large ones. London and every South East county are within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Will all the toilets be closed at once?

Only the area we are working in is closed. Rooms go back into use once the sealant has cured and we start the next.

How many days will you need on site?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

What guarantee comes with washroom resealing?

Our workmanship has a 12-month guarantee backed by public liability insurance.

Can you reseal washrooms in healthcare buildings?

Yes, healthcare and care settings are part of our work. Tell us what records you need and we will confirm with the quote.

Can the sealant be colour-matched?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.

Common problems we fix in Frithend

A lot of failed washroom sealant was laid over an old bead or a dirty surface. Silicone won’t adhere to a silicone bead, so it soon lets go.

Most enquiries start with one or more of the following:

  • Kitchen worktop joints that can’t be kept clean
  • Sealant stained black around basins and showers
  • Users noticing mouldy joints
  • Shower tray joints that have opened up

At a university such as University for the Creative Arts, 4.6 miles north-east of Frithend, summer is the usual window for resealing residence bathrooms.

Before you book anyone

  • Whether primer will be used where the manufacturer specifies it
  • How they’ll work around occupants
  • Proof of insurance
  • The terms of the workmanship guarantee

Questions to ask before you appoint anyone

Keeping Frithend washrooms open while we work

Frithend lies roughly 40 miles out from central London. Washrooms in commuter-belt offices take constant weekday traffic, so we phase work to keep some facilities open.

Units at estates like Blacknest Industrial Park, 1.3 miles north-west of Frithend, have welfare blocks whose showers and toilets see shift after shift.

Diagnose, treat, sign off

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. Rural sites near Frithend may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
  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. We clean and dry every surface so the new sealant can grip.
  5. New sanitary silicone with anti-mould additives goes in and is tooled neat.
  6. Rooms reopen after the product’s cure time, and we move to the next.

Before we start on site

  • Confirm the product named in the specification
  • Make sure the joints can be reached
  • Arrange parking or a loading space

Advice

What sealant work can’t fix

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • A dripping waste or valve behind a panel
  • Panel boards already damaged by water
  • Hollow tiles or loose panels behind the joint

If you are not sure, just phone 01277 525 020 or send photos by email and we’ll give you a straight answer.

Joints and surfaces we work on

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

When to bring in a specialist

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
