Questions about Cramhurst

Is a hospital such as Milford Hospital somewhere you can work?

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 Cramhurst too far out for you?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Do you take on small jobs?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

What do you charge?

Each job is quoted on its own details. For yours, call 01277 525 020 or send details through our quote form with a description of the work.

Who decides which product is used?

The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

What about RAMS and site documents?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

How do you deal with asbestos in old sealant?

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.

About our washroom sealing in Cramhurst

Black spotting along a sealant bead is not a cleaning problem. The growth is inside the sealant, which is why it comes back however often it is treated. Only replacement gets rid of it for good. We work on showers, trays and wet room floors, kitchens and tea points and urinals and WCs, and the usual reasons a site gets in touch are stained sealant around pans and urinals and open joints at the base of cubicle panels. Facilities teams, main contractors and managing agents in Cramhurst tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Halls and community buildings near places like Cramhurst are used by different groups through the week, and their toilets and kitchens show it. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.

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

Keeping the joints sound

Keep the joints in good shape with a few simple steps:

  • Mention any site permits or estates rules at quote stage
  • Clean sealant with gentle products and a soft cloth
  • Keep a record of which washrooms need attention
  • Don’t leave an open joint at a basin or tray

Ask your cleaning team to use gentle products and soft cloths on sealant. Strong acids, solvents and scourers wear the surface over time.

A few failed joints can be resealed with hardly any disruption. Left, it tends to become a building-wide job with more phasing to plan.

Different surfaces, different methods

Healthcare and care settings

Accessible and assisted washrooms are used and cleaned intensively so their sealant tends to fail sooner.

Urinals and WC pans

Joints around urinals and WC pans take splashes, cleaning chemicals and knocks. Stained or split joints here trap smells and look unhygienic.

Honest limits

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Water from plumbing, not from a joint
  • A room that stays damp because ventilation isn’t working
  • Failed tanking beneath a wet-room floor or behind tiles

Not sure which it is? You can ring 01277 525 020 or use the quote form and we will tell you honestly.

What we seal

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

What we’re called out for in Cramhurst

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 peels away quickly.

It’s worth sending us details if you spot any of the following:

  • Split or peeling sealant at shower trays
  • Black mould inside silicone joints that cleaning can’t shift
  • Stained sealant around pans and urinals
  • Open joints at the base of cubicle panels

At a hotel such as The White Hart Hotel, 0.9 miles to the south-east of Cramhurst, the quieter weeks are the time to reseal bathrooms.

Before you book anyone

  • How joint depth will be controlled
  • How they handle RAMS and site documents
  • Whether primer will be used where the manufacturer specifies it
  • Whether old or failed sealant will be cut out, not overlaid

How to choose a sealant contractor

Diagnose, treat, sign off

Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For work around Cramhurst, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. First, the phasing is agreed so facilities stay open.
  2. Leaks, loose panels or damp are pointed out first.
  3. Failed sealant and residue are stripped out.
  4. We reseal with the grade suited to each area.
  5. We confirm reopening times for each washroom.

What we need from you

  • Send your site hours and access windows
  • Clear stock, furniture or equipment away from the joints
  • Send any specification or drawings in advance

Getting a fixed quote

The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or ring 01277 525 020 or email the details over to discuss it first.

Advice

When to bring in a specialist

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
