Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Quoting for work in Great Parndon

A fixed quote reflects the actual work. It takes account of:

  • The product specified
  • Whether the work must be split into stages
  • Quantities, in metres or numbers
  • Joint width, depth and condition

The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Before you send an enquiry

We can often quote from photographs and a few details. Please tell us:

  • Drawings or a marked-up plan, if available
  • When you need the work done
  • The asbestos register, for older buildings
  • How the joints are reached, and at what height

Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, phone 01277 525 020 or email the details over.

Around Great Parndon, washroom work normally comes one building at a time. Photos of each area help us plan the visit and bring the right sealant.

Doing it in-house

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Washroom sealing around Great Parndon: what changes locally

A 2-mile radius around Great Parndon takes in a number of hotels. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. The work can go floor by floor, agreed with housekeeping. Great Parndon lies roughly 19 miles out from central London. Washrooms in commuter-belt offices take constant weekday traffic, so we phase work to keep some facilities open.

Halls linked to places like Church of St Mary the Virgin host groups all week, which is hard on kitchen and toilet sealant. At a college such as Harlow College, 1.3 miles north-east of Great Parndon, washroom and kitchen sealant is best renewed in the holidays or in phases during term. At a hospital like Princess Alexandra Hospital (1 mile north of Great Parndon), patient and staff washrooms are best done in short phases agreed with the ward.

Great Parndon is about 2 miles south-west of Harlow, in Essex. We cover commercial sites throughout Great Parndon. We work across 644 places in Essex, large and small. There’s a separate page for London, about 19 miles away.

How a job runs

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes between a morning and a week or so, set by the number of rooms and the phasing you need, and our waste is bagged and taken away as we go. If neighbouring businesses or buildings around Great Parndon need work too, visits can be combined. Mention the building’s opening times and we will work within them.

When something else is needed

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • A room that stays damp because ventilation isn’t working
  • Water escaping beneath the floor rather than through a joint

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

Surfaces we seal

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

What happens if it’s left?

Water gets behind panels and under floors through a failed joint. That can lead to swollen boards, marked ceilings below and lingering smells, and fixing that takes far more work than resealing. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Common questions from Great Parndon clients

Could you schedule work at a campus like Harlow College for the vacation?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Is Great Parndon off your patch?

Not at all. Great Parndon is within our area. 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.

How do we ask for a quote?

The quote form is the simplest route, though you can also phone 01277 525 020 or email us. Include photos or drawings if you have them.

Do you need to remove the old sealant?

The failed bead is always removed. New silicone won’t stick to the old, so sealing over it soon peels.

Do you take on multi-site work?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

Can you clean the mould off instead of resealing?

Normally not. Mould grows into the sealant itself, so it comes back however often it’s cleaned. Replacement is the lasting fix.

What do you charge?

There isn’t a price list, as every site differs. With photos or drawings, we can give you a fixed quote.

Work for main contractors and building owners

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
