Washroom sealing near Saunderton Lee

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

FAQs: Saunderton Lee

Do we have to close all our washrooms in Saunderton Lee for resealing?

Rarely all at once: work is phased so some facilities are always available. We’ll tell you the curing time for the product before we start.

Is a smaller place like Saunderton Lee outside your area?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

When is resealing likely to be due?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Do you need to remove the old sealant?

The failed bead is always removed. New silicone won’t stick to the old so a bead over the top fails quickly.

Who decides which product is used?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Do you offer coloured sealant?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

Can you clean the mould off instead of resealing?

Normally not. Mould grows into the sealant itself so cleaning only lightens it for a while. Replacing the bead is the lasting answer.

Washroom sealing for commercial buildings in Saunderton Lee

In a commercial washroom, sealant is usually the first thing to wear out. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day, and once mould grows into it, it can’t be scrubbed out. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. If you have black mould inside silicone joints that cleaning can’t shift and failed sealant behind washroom basins, we can put it right, whatever the surface. Searching for sealant specialists in Saunderton Lee? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

Halls and community buildings near places like Saunderton Lee 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.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:

  • A room that stays damp because ventilation isn’t working
  • Loose panels, vanity units or tiles, which need fixing first
  • Leaks through tanking or membranes below the finishes

Not sure which it is? You can phone 01277 525 020 or send details through our quote form and we will tell you honestly.

Surfaces we seal

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

How a job runs

Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. If others near Saunderton Lee need work, visits can be combined. A fixed quote is given before anything starts.

  1. We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
  2. A phasing plan keeps part of the building’s facilities in use at all times.
  3. We strip out the old bead and clean off the residue left behind.
  4. We clean and dry every surface so the new sealant can grip.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. You get a reopening time for every room, with signage left up until then.

Getting the site ready

  • Clear stock, furniture or equipment away from the joints
  • Send asbestos survey details if the building is pre-2000
  • Explain the parking and delivery arrangements

Advice

Why it’s worth doing now in Saunderton Lee

Open or mouldy joints are hard to keep hygienic, and in kitchens, clinics and schools that is a real concern. A smooth, sealed joint can be cleaned properly. Older rural buildings around Saunderton Lee move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.

What you get with us

  • A range of standard colours, depending on the product
  • 12 months’ guarantee on every job
  • Products installed to the manufacturer’s instructions
  • CHAS accredited

Keeping Saunderton Lee washrooms open while we work

Saunderton Lee lies roughly 34 miles out from central London, within the office belt around the capital. Office toilets in the commuter belt are in use from first arrivals to last departures, and resealing in phases keeps facilities available.

At a school such as St John's Church of England Primary School, changing rooms and kitchens need cleanable joints as much as the toilets. On an industrial estate such as Crownfield Industrial Estate, less than half a mile to the south-east of Saunderton Lee, staff toilets, showers and canteens are where sanitary sealant takes the most wear.

Do you need washroom sealing in Saunderton Lee?

Occasionally a joint keeps failing because of a problem behind it: loose fixings, a dripping trap or damp in the wall. We look for it before resealing and tell you if another trade is needed.

Things that usually lead to an enquiry:

  • Panel joints letting water behind
  • Split or peeling sealant at shower trays
  • Stained sealant around pans and urinals
  • Sealant stained black around basins and showers

Clinical washrooms at sites like The Paddocks Hospital, 2.7 miles north of Saunderton Lee, are scheduled with the ward so the room is out of use for as little time as possible.
