Washroom sealing for South Heath sites

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

About our washroom sealing in South Heath

Accessible WCs, showers and changing areas have their own pinch points: shower trays, wet-room floor edges, basins and floor-to-wall junctions. An open joint there lets water track under flooring or behind wall panels, so we look at them closely. If you’re dealing with sealant lifting along a tray edge and panel joints letting water behind, we can help, whatever the surface. Looking for mastic applicators who cover South Heath? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.

Farm shops, cafés and venues in converted rural buildings around places like South Heath have busy toilets and kitchens. Tell us your opening times and quiet periods and we will plan around them.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Different surfaces, different methods

Healthcare and care settings

We phase washroom sealing so care areas are never left without facilities. Tell us what records you need and we’ll confirm with the quote.

Urinals and WC pans

The joint between a pan and the floor is easy to overlook. We include them in the survey.

When something else is needed

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:

  • Fittings that move too much to hold a bead
  • Water escaping beneath the floor rather than through a joint
  • Vanity carcasses that have swollen

If you’re not sure, just give us a call on 01277 525 020 or email us and we will give you a straight answer before you book.

Where we work in South Heath

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

Building owners, agents and FMs in South Heath

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in South Heath can sit alongside others in a wider programme across Buckinghamshire.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios around South Heath. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Keeping South Heath washrooms open while we work

Central London is about 29 miles from South Heath, within the office belt around the capital. Business park offices have washrooms in daily use by staff, which is why the work is phased.

At a hospital like The Chiltern Hospital (1.3 miles south of South Heath), patient and staff washrooms are best done in short phases agreed with the ward. Halls linked to places like St Mary's host groups all week, which is hard on kitchen and toilet sealant.

South Heath is about 3 miles west of Chesham, in Buckinghamshire. Anywhere in HP16, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 308 places in Buckinghamshire. Reading is covered too, some 22 miles away.

Postcode districts covered here: HP16. Streets here include Meadow Lane, Lappetts Lane and Wood Lane, and sites on any of them can send details for a fixed quote. Just outside South Heath, we also work in Hyde End (1 mile south-east), Ballinger Common (1 mile north), Hundridge (1 mile east), Lee Common (1 mile north) and Chartridge (2 miles north-east). Further afield, our area takes in Aylesbury (9 miles north-west), High Wycombe (6 miles south-west), Chesham (3 miles east), Marlow (10 miles south-west), Amersham (4 miles south-east) and Beaconsfield (7 miles south).

Around South Heath

Around South Heath, our work takes us to commercial buildings near Annie Baileys pub, The Misbourne School and Missenden Abbey Adult Education College and the streets around them. The nearest railway station is Great Missenden station, about 1.2 miles west of the centre. Nearby you’ll also find Chiltern Hospital (1.3 miles south) and Great Missenden (0.9 miles south). Not far away are Pavis Wood and Sands Bank.

Should maintenance staff do it?

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

From enquiry to sign-off

Site rules come first: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, we take the joints in the sequence agreed with you. Smaller jobs around South Heath can be grouped with others nearby. You will have a fixed quote before work starts.

  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 give you a reopening time for every room.

What we need from you

  • Point out parking and an unloading spot
  • Share the asbestos register for older buildings
  • Let building users know which areas are affected

Quotes

Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Related advice

South Heath: questions and answers

Is hospital work, at somewhere like The Chiltern Hospital, something you do?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

Can you work around term dates at a campus such as Buckinghamshire New 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.

Who decides which product is used?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Will your applicators have CSCS cards?

Yes. We use CSCS-carded applicators.

Can the sealant be colour-matched?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

Do you work to architects’ specifications?

Yes. Send it with your enquiry, and we will price the work to it.

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

Common problems we fix in South Heath

Low-level joints get hit by mop buckets, cleaning trolleys and feet at skirting lines, urinal bases and around pans.

Any of the following is a good reason to get the joints checked over:

  • Washrooms that look worn because of the sealant
  • Discoloured joints around urinals and WC pans
  • Sealant laid over old silicone and now peeling
  • Sealant lifting along a tray edge

For a school such as Great Missenden CofE Combined School, washroom and kitchen sealant can be renewed around term dates.
