Common questions from Maple Cross clients

Can you take on a job at a hospital such as Harefield Hospital?

Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.

Can you work in a care home near Maple Cross with residents in?

Yes. Care settings are planned area by area, at times agreed with the home. We follow the home’s own procedures throughout.

How long does a typical visit take?

That varies with the scale of the job, though a typical visit normally takes a morning or so for a small washroom, longer where showers and changing rooms are included. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

What will the job cost?

There isn’t a price list, because every site is different. With photographs or drawings, we can give you a fixed quote.

Do you use special sealant for toilets and showers?

Sanitary silicone with anti-mould additives for most washroom joints. We use neutral-cure versions on stone, some metals and near mirrors.

Is it possible to just clean mouldy silicone?

Surface cleaning won’t reach mould that has rooted into the bead. New anti-mould sanitary silicone is the treatment and point out if ventilation is part of the problem.

Are your applicators CSCS-carded?

Yes. We use CSCS-carded applicators.

Washroom sealing for commercial buildings in Maple Cross

We reseal washrooms and wet areas in offices, hotels, schools, universities, gyms, healthcare buildings 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. The enquiries we see most involve open joints along basins and vanity units and stained sealant around pans and urinals, across kitchens and tea points, urinals and WCs and IPS panels and cubicles. Facilities teams, main contractors and managing agents in Maple Cross 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 Maple Cross 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.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

What affects the price in Maple Cross

Sealant work doesn’t have a standard rate, because every site is different. What we look at:

  • Any access equipment needed
  • Which sealant the job calls for
  • Site requirements such as inductions and permits
  • Distance, for remote addresses

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Sending details for a quote

For an accurate fixed quote, we need to understand the site. Send us:

  • What the building is and how it’s used
  • The asbestos register, for older buildings
  • Where the site is, with the postcode
  • How the joints are reached, and at what height

Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote that you can work with. If you have questions first, give us a call on 01277 525 020 or send details through our quote form.

Why it’s worth doing now in Maple Cross

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. For buildings around smaller places like Maple Cross, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

What you get with us

  • Workmanship guaranteed for 12 months
  • Coloured sealants to suit the setting, where available
  • CHAS accredited
  • Specification-led, product-correct work

Wet areas in Maple Cross’s workplaces

Central London is about 20 miles from Maple Cross, in a commuter belt where offices and business parks are common. Washrooms in commuter-belt offices take constant weekday traffic, which is why the work is phased. Maple Cross has three care or nursing homes no more than 2 miles away. Assisted bathrooms and wet rooms in care settings need sanitary sealant that stays cleanable. Each room is kept out of use only as long as the sealant needs.

On an industrial estate such as Woodcock Hill Industrial Estate, 1.9 miles to the east of Maple Cross, staff toilets, showers and canteens are where sanitary sealant takes the most wear. At a school such as Maple Cross Junior Mixed Infant and Nursery School, changing rooms and kitchens need cleanable joints as much as the toilets.

What we’re called out for in Maple Cross

Low-level joints get hit by mop buckets, cleaning trolleys and feet, especially at floor edges and around urinals and WC pans.

Common reasons buildings call us in:

  • Washrooms that look worn because of the sealant
  • Panel joints letting water behind
  • Stained sealant around pans and urinals
  • Failed sealant behind washroom basins

For a hall at a building such as Church of St Thomas of Canterbury, resealing the kitchen and toilets can be fitted between bookings.

Questions to ask before you appoint anyone

How the job changes by surface

Showers and trays

Shower trays move under foot and are wet all day. Tray perimeters are a frequent source of leaks.

Changing rooms and gyms

Showers, floor edges and vanity units in changing rooms all need sound sealant, and we survey them together.

Building owners, agents and FMs in Maple Cross

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Maple Cross can form part of a wider programme across Hertfordshire.

Building owners and managing agents use us on everything from one building to a spread of sites around Maple Cross. One quote can cover more than one site, which keeps the paperwork simple.

Our process

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. If others near Maple Cross need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.

  1. We inspect each washroom and record the joints to be resealed.
  2. You get a fixed quote with the phasing plan.
  3. Old sealant is removed completely and the faces cleaned.
  4. Each joint is cleaned and left dry.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Each area is handed back when ready.

Before we start on site

  • Share your working hours and any access restrictions
  • Tell us which areas need to stay in use
  • Make sure the joints can be reached
