Petts Wood: questions and answers

Can you work in a care home near Petts Wood with residents in?

Yes, with the manager deciding the order and timing of rooms. Tell us about any infection-control or safeguarding requirements and we’ll work to them.

Can you cope with the access rules in a London building?

Yes, we plan every London job around the building’s own access rules. Share the building’s contractor rules and we’ll work to them. The ULEZ covers the whole of Greater London, which we allow for

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. Work pauses if suspect material is found, until it has been tested.

Can weather delay the job?

Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Are you CHAS accredited?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

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.

What will the job cost?

There isn’t a price list, because every site is different. Send photographs or drawings and we will price it at a fixed figure.

Washroom sealing in Petts Wood

Black spotting along a sealant bead is not a cleaning problem. The mould has rooted into the silicone itself so it returns whatever the cleaning regime. Only replacement gets rid of it for good. Most enquiries involve complaints from staff, guests or users about tired washrooms and sealant lifting along a tray edge, on IPS panels and cubicles, showers, trays and wet room floors and urinals and WCs. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Petts Wood, preparation and product choice get the time they need.

In a London area such as Petts Wood, commercial washrooms in offices, hotels and leisure buildings see constant use. We cut out tired sealant around vanity units, cubicles, IPS panels and showers and lay fresh anti-mould sanitary silicone, a block of facilities at a time.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

How the job changes by surface

Urinals and WC pans

The joint between a pan and the floor is easy to overlook. They are checked with everything else.

Changing rooms and gyms

We phase work so not every changing area is closed at once. Tell us your site hours and access windows and we’ll plan around them.

After the work

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Add sealant joints to planned maintenance checks
  • Don’t leave trays and floors sitting wet
  • Leave signs up until the cure time is over
  • Act on the first split you see at a shower tray

Add washroom sealant to routine inspections. Check for mould spots, splits, lifting edges and open joints at trays, basins and urinals and photograph anything new.

Inspectors look at whether kitchen surfaces can be kept clean. Failed sealant around sinks and worktops is easy to put right in good time.

Quoting for work in Petts Wood

To price the job, we consider:

  • Specialist products, such as fire-rated or hygienic sealants
  • Backing rod, priming and other preparation
  • Travel to remote or island sites
  • How much there is to seal

We don’t publish prices, since every building and every scope is different. Call for a quote.

Details that help us quote

Whether it’s one area or a whole building, the same details help:

  • The product your specification calls for
  • The type of building and who uses it
  • Drawings or a marked-up plan, if available
  • Any dates the work must fit around

Why deal with it now?

Open or mouldy joints are hard to keep hygienic which matters most in healthcare, food and education settings. Sound, smooth joints are much easier to keep clean. Getting scaffold, permits or access booked in Petts Wood takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.

Pricing washrooms and wet areas depends on quantities, condition and access. Ask us for a fixed quote.

Why us?

  • RAL and finish matching where the product range allows
  • One phone line for London, the South East and Scotland
  • Clear, fixed quotes
  • Fully insured, including public liability cover

How a job runs

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.

  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. 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. You get a reopening time for every room, with signage left up until then.

Getting the site ready

  • Send any specification or drawings in advance
  • Tell us what induction or permit system the site runs
  • For older buildings, check the asbestos register before work

Quotes

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, call 01277 525 020 or use the quote form.

Related advice

Common problems we fix in Petts Wood

Panels and vanity units move slightly in use, and shower trays shift under foot. A bead that can’t cope with the movement splits along one edge.

These are often picked up first by site or facilities staff:

  • Panel joints letting water behind
  • Kitchen worktop joints that can’t be kept clean
  • Shower tray joints that have opened up
  • Washrooms that look worn because of the sealant

Colleges such as Bromley College, 1.8 miles to the west of Petts Wood, have toilets, changing rooms and catering kitchens that can be resealed around term dates.

Questions to ask before you book

  • Whether primer will be used where the manufacturer specifies it
  • Proof of insurance
  • What the guarantee covers, and for how long
  • Whether their applicators hold CSCS cards
