Washroom sealing for commercial buildings in Woodside Green

Our washroom work covers offices, hotels, schools and colleges, leisure centres and gyms, clinics and care homes, plus the kitchens and tea points that go with them. Product and method follow how hard each area is used and cleaned. We work on showers, trays and wet room floors, vanity units and basins and kitchens and tea points, and the usual reasons a site gets in touch are shower tray joints that have opened up and washrooms that look worn because of the sealant. For commercial sealant work in Woodside Green, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Smaller places such as Woodside Green 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.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

How the job changes by surface

Kitchens and tea points

We plan kitchen sealing around when the kitchen is in use. Your site hours and access windows set the timing.

IPS and cubicle panels

IPS panels and cubicle systems have joints at the wall, the floor and the worktop. Those joints protect the boards behind from water.

On site: what to expect

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself usually taking between a morning and a week or so, set by the number of rooms and the phasing you need. For a building around Woodside Green, tell us how to find it and who will meet us. Add it to your enquiry and we’ll 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. A phasing plan keeps part of the building’s facilities in use at all times.
  3. We strip out the old bead and clean off the residue left behind.
  4. Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
  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.

What we need from you

  • Explain the parking and delivery arrangements
  • Send asbestos survey details if the building is pre-2000
  • Let building users know which areas are affected

Why deal with it now?

Water gets behind panels and under floors through a failed joint. That can lead to swollen boards, marked ceilings below and lingering smells which costs more to fix than a reseal. Around Woodside Green, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

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 we’ll put a fixed figure on it.

Why appoint us

  • Coloured sealants to suit the setting, where available
  • Old sealant cut out, never sealed over
  • CHAS accredited contractor

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

What affects the price in Woodside Green

To price the job, we consider:

  • Backing rod, priming and other preparation
  • Which sealant the job calls for
  • Phasing around occupants
  • How much there is to seal

The product called for affects the cost, and so does the preparation. Access, phasing and site requirements come into it too.

Before you send an enquiry

To price the job accurately, we need a clear picture of the site. Send us:

  • When you need the work done
  • Access details, including height
  • Where the site is, with the postcode
  • Whether an asbestos survey exists

To get a fixed quote, phone 01277 525 020 or email drawings and photos, telling us the site location and the nature of the job. You can also send details through our quote form.

Questions about Woodside Green

Can you work around term dates at a campus such as Canterbury Christ Church University?

Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Must every washroom in our Woodside Green building shut while you work?

Rarely all at once: work is phased so some facilities are always available. We’ll tell you the curing time for the product before we start.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

How long does a typical visit take?

It depends on the scope, but the work usually takes between a morning and a week or so, set by the number of rooms and the phasing you need. For bigger or phased jobs, we will set out a timescale with the quote.

How long before the toilets can reopen?

Cure times vary by product and temperature. You’ll get a reopening time for each area, and signs stay up until then.

What’s the quickest route to a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.

Commercial washrooms in Woodside Green

Central London is about 39 miles from Woodside Green, in a commuter belt where offices and business parks are common. Washrooms in commuter-belt offices take constant weekday traffic, so we work a block of facilities at a time.

Church halls and community buildings, such as those at St Mary's Church, have kitchens and toilets used by many groups, and their sanitary sealant works hard. Office washrooms on sites such as Roebuck Business Park (to the west of Woodside Green) are in use all working day, so resealing is phased to keep some open. Student showers at universities like Canterbury Christ Church University (2.4 miles north-west of Woodside Green) see more use than most, and their silicone shows it.

Owners, agents and contractors

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Woodside Green can sit alongside others in a wider programme across Kent.

As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.

Keeping the joints sound

Problems stay small when the joints are checked regularly. Specifically:

  • Keep a record of which washrooms need attention
  • Add sealant joints to planned maintenance checks
  • Don’t leave an open joint at a basin or tray
  • Make sure washroom ventilation is running

Ventilation is half the battle. Constant damp lets mould take hold even on anti-mould grades so report fans that aren’t working to your building services team.

Small numbers of failed joints are quick to phase in. Left until every washroom is affected, it becomes a bigger programme with more phasing to plan.
