Washroom sealing near Postling Green

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Should maintenance staff do it?

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Commercial washrooms in Postling Green

Postling Green lies roughly 54 miles out from central London, within the office belt around the capital. Washrooms in commuter-belt offices take constant weekday traffic, and resealing in phases keeps facilities available.

For buildings on a site such as Evegate Business Park (2.2 miles north of Postling Green), washrooms and tea points can be resealed in phases through the working week.

Your questions answered

Is a smaller place like Postling Green outside your area?

No. Places such as Postling Green are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Will the toilets in our Postling Green building be out of use?

Usually only some of them, for a short time. We work in phases so other facilities stay open. Sanitary silicone needs time to cure before the area is used, and we will tell you how long for the product used.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.

Can you reseal washrooms in healthcare buildings?

We work in clinics, hospitals and care homes. Tell us what records you need and we will confirm with the quote.

What sealant do you use in washrooms?

Each area gets the grade that suits it. Washrooms and showers take anti-mould sanitary silicone, and food areas take a hygienic, food-safe sealant where food contact is possible.

What happens if old sealant might contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

Do you guarantee washroom sealing?

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

Our process

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 the sealant is tooled off neatly. Jobs in and around smaller places like Postling Green are typically planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. The phasing is agreed so there are always facilities open.
  3. The failed silicone is stripped and every face scraped clean of residue.
  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. Each room is handed back once the sealant has had its cure time.

Getting the site ready

Advice

What sets the cost

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

  • Joint width, depth and condition
  • Access and working height
  • Working within restricted access windows
  • Induction, permit and paperwork requirements

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

What to include in your enquiry

A good diagnosis starts with the right details. Tell us:

  • The asbestos register, for older buildings
  • Clear photos of the problem areas
  • Any dates the work must fit around
  • What the building is and how it’s used

Need a figure for a tender or a budget? Send the scope and any drawings, and we’ll return a fixed quote you can plan around. For a chat about it beforehand, speak to us on 01277 525 020 or email drawings and photos.

Why deal with it now?

Running fresh silicone along a failed bead hides the problem briefly. Silicone won’t grip silicone, so it lifts and holds moisture underneath. Full removal and proper cleaning is what makes the new joint last. One visit to deal with every failing joint makes more sense than several trips to a place like Postling Green. Photos of every joint help us quote for the whole job.

There’s no price list, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.

Why appoint us

  • Fully insured, including public liability cover
  • Coloured sealants to suit the setting, where available
  • Colour options checked against the specified product
  • Health and safety: CHAS accredited

What the job involves on each surface

Basins and vanity tops

Stone and some composite tops need a neutral-cure sealant and we choose a neutral-cure grade for them.

Kitchens and tea points

Worktop, sink and splashback joints in tea points take water and food. Sound joints keep those surfaces easy to clean.

Keeping the joints sound

Problems stay small when the joints are checked regularly. In particular:

  • Report faulty extraction promptly
  • Tell us about infection-control or permit rules before we quote
  • Respect the cure time before reopening each room
  • Don’t leave trays and floors sitting wet

Ventilation is half the battle. A room that stays damp will grow mould on almost anything, so get faulty extract looked at.

A split joint at a shower tray can leak for a long time before anyone sees it. At that stage, boards or ceilings may need repair so failed joints are worth acting on quickly.
