Washroom sealing in Great Holcombe, done properly

We reseal washrooms and wet areas in offices, hotels, schools, universities, gyms, healthcare buildings and care homes, along with staff kitchens and tea points. The products and the method are chosen for how heavily each space is used. If you have shower tray joints that have opened up and mould spotting along silicone joints, we can help, on accessible toilets and changing rooms, showers, trays and wet room floors and vanity units and basins alike. Whoever orders the work in Great Holcombe, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

Community buildings around smaller places like Great Holcombe have kitchens and toilets used by many people. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant.

Washroom sealing in Great Holcombe: the local picture

At about 45 miles from central London, Great Holcombe is within reach of the capital, within the office belt around the capital. Office toilets in the commuter belt are in use from first arrivals to last departures, which is why the work is phased.

For buildings on a site such as Monument Business Park, which lies east of Great Holcombe, washrooms and tea points can be resealed in phases through the working week. For a hall at a building such as Church of St Giles, resealing the kitchen and toilets can be fitted between bookings. Staff changing rooms and patient toilets at places like Littlemore Hospital (5.8 miles north-west of Great Holcombe) need cleanable, sound silicone.

What sets the cost

The price varies from site to site. It mainly depends on:

  • Quantities, in metres or numbers
  • Travel to remote or island sites
  • Specialist products, such as fire-rated or hygienic sealants
  • Backing rod, priming and other preparation

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

Details that help us quote

It doesn’t need to be a full survey. These details are enough to start:

  • Whether an asbestos survey exists
  • The site address and postcode
  • The product your specification calls for
  • Whether the building will be occupied during the work

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, speak to us on 01277 525 020 or email drawings and photos.

On site: what to expect

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. Smaller jobs around Great Holcombe can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.

  1. We agree which washrooms close and when.
  2. Leaks, loose panels or damp are pointed out first.
  3. Old sealant is stripped and the faces prepared.
  4. The right sanitary or food-safe sealant is applied.
  5. We give you a reopening time for every room.

Preparing the site

  • Tell us what induction or permit system the site runs
  • Point out any areas we must not close
  • Send your site hours and access windows

Doing it in-house

Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

For managing agents and facilities managers

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios. Several sites can go on one quote, which keeps the paperwork simple.

Aftercare for building managers

Cleaning and maintenance staff play a part too. Share these points with them:

  • Clear standing water from shower floors where possible
  • Share your site rules when you send details
  • Keep extract fans working and vents clear
  • Respect the cure time before reopening each room

We hand each area back once the silicone has had the cure time the product needs. We’ll tell you when the wet areas can be used and signage stays in place until that time.

Mouldy sealant only gets harder to ignore, and complaints follow. Replacing it early keeps the job to a reseal.

Questions about Great Holcombe

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

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

Will all the washrooms in our Great Holcombe building be closed at once?

Not all at once. We take one block of facilities at a time. Sanitary silicone needs time to cure before the area is used, and we’ll tell you how long for the product used.

What about RAMS and site documents?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Do you need to remove the old sealant?

We strip every bit of the failed bead and wipe away the residue before resealing. It’s the difference between a joint that lasts and one that peels.

Can one quote cover more than one building?

Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators.

Why deal with it now?

Gaps and mould in joints give dirt and bacteria somewhere to sit which matters most in healthcare, food and education settings. A smooth, sealed joint can be cleaned properly. One visit to deal with every failing joint makes more sense than several trips to a place like Great Holcombe. Send photos of each area and we will quote for the lot.

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Why us?

  • Products installed to the manufacturer’s instructions
  • Over 20 years of commercial sealing
  • Public liability insurance in place
  • Coloured sealants to suit the setting, where available
