Washroom sealing in Gerrards Cross, done properly
When mould has spotted a silicone joint, more cleaning won’t remove it. The mould has rooted into the silicone itself so it returns whatever the cleaning regime. Replacing the bead is the lasting treatment. If you have washrooms that look worn because of the sealant and mould spotting along silicone joints, we can put it right, on accessible toilets and changing rooms, kitchens and tea points and urinals and WCs alike. Looking for mastic applicators who cover Gerrards Cross? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.
In a smaller place such as Gerrards Cross, commercial washrooms tend to be in schools, pubs, cafés, surgeries, care homes and sports clubs. However small, each needs the old sealant removed completely and anti-mould sanitary silicone applied to clean, dry joints.
Every job we finish is backed by a 12-month workmanship guarantee, in Gerrards Cross as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Gerrards Cross: questions and answers
Can you work around term dates at a campus such as Buckinghamshire New University?
Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Would you work within a site like Spire Thames Valley Hospital?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can you quote from photographs?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit before quoting.
Does the weather affect the work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Can you work to our specification?
Yes. Send it with your enquiry, and we’ll price the work to it, flagging anything that needs clarifying.
How long before the toilets can reopen?
Cure times vary by product and temperature. Each room gets its own reopening time from us, and signs stay up until then.
Do you guarantee washroom sealing?
A 12-month guarantee covers the work. It covers our workmanship rather than damage, leaks from plumbing or ventilation problems.
Work for main contractors and building owners
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Gerrards Cross can form part of a wider programme across Buckinghamshire.
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

What we can’t put right
We check first that sealant really is the fix. It isn’t the answer for:
- Failed tanking beneath a wet-room floor or behind tiles
- Leaking pipes, traps, wastes or cisterns, which need a plumber
- Swollen or delaminated boards behind panels or vanity tops
Not sure which it is? You can give us a call on 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.

Related advice
Leave it or put it right?
Sealing on top of old silicone saves nothing. It doesn’t bond, so it peels and traps dirt behind it. Full removal and proper cleaning is what makes the new joint last. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.
The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.

Should maintenance staff do it?
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
How the quote is worked out
What shapes the price:
- Any access equipment needed
- Induction, permit and paperwork requirements
- Which sealant the job calls for
- Phasing around occupants
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
