Washroom sealing in Swan Bottom: the local picture

At about 31 miles from central London, Swan Bottom is within reach of the capital. Business park offices have washrooms in daily use by staff, which is why the work is phased.

Halls linked to places like Parish Church of St John the Baptist host groups all week, which is hard on kitchen and toilet sealant. Staff changing rooms and patient toilets at places like Chiltern Hospital (to the south of Swan Bottom) need cleanable, sound silicone. At a university such as Buckinghamshire New University, which lies south-east of Swan Bottom, summer is the usual window for resealing residence bathrooms.

Swan Bottom is about 4 miles north-west of Chesham, in Buckinghamshire. Anywhere in HP16, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Across Buckinghamshire, 308 places are covered, Swan Bottom among them. We also cover Reading, some 23 miles away.

On site: what to expect

Tell us your site hours and access windows and we will plan around them. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. For work around Swan Bottom, 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. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. We agree which rooms close and when, so users always have somewhere to go.
  3. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. Joints are cleaned, degreased and dried before sealing.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. Each room is handed back once the sealant has had its cure time.

Preparing the site

  • Agree which areas must stay open
  • Flag any permit to work we will need
  • Send your site hours and access windows

Why act early in Swan Bottom

Cleaning mouldy sealant only masks it but the growth is inside the bead and returns. A full reseal deals with it and your cleaning team stops chasing it. Around Swan Bottom, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

When it isn’t the sealant

Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:

  • Mould caused by poor ventilation, which will return until the extract is fixed
  • Leaking pipes, traps, wastes or cisterns, which need a plumber
  • Vanity carcasses that have swollen

If you’re not sure, just phone 01277 525 020 or send details through our quote form and we’ll give you a straight answer.

What the job involves on each surface

Healthcare and care settings

Healthcare work is phased so wards, clinics or residents’ areas keep their facilities. Tell us what records you need and we will confirm with the quote.

Kitchens and tea points

Kitchen joints need to be smooth and sealed so they can be cleaned properly. Food-safe sealants are used where food may touch the joint.

How the quote is worked out

To price the job, we consider:

  • Specialist products, such as fire-rated or hygienic sealants
  • How much there is to seal
  • How accessible the joints are
  • Location, for remote and island sites

A quote for washrooms and wet areas depends on quantities, condition and access, plus any specification you are working to. Call for a quote.

What to include in your enquiry

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

  • Any dates the work must fit around
  • The product your specification calls for
  • The site address and postcode
  • Access details, including height

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

FAQs: Swan Bottom

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

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

Is Swan Bottom too small for you to travel to?

Not at all. Swan Bottom is within our area. We work across Greater London and the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Can you send site paperwork?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

What happens if old sealant might contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

What will the job cost?

That depends on the job: quantities, access, the product and any phasing. Call for a quote.

Can you quote from photographs?

It depends on the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.

How do you choose the sealant?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
