Our process
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 handed back before the next one starts. Jobs in and around smaller places like Gravesend are usually planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- We inspect each washroom and record the joints to be resealed.
- The fixed quote sets out the rooms, the products and the phasing.
- The whole of the old bead is removed.
- Each joint is cleaned and left dry.
- A sanitary silicone bead is laid and given a smooth tooled finish.
- Rooms reopen after the cure time.
What we need from you
- Send your site hours and access windows
- Make sure the joints can be reached
- Have the specification and drawings to hand

How we handle washroom sealing in Gravesend
You can’t shut every toilet in an office, school or hotel at once. We phase the work one washroom, one bank of cubicles or one changing room at a time, so there are always facilities in use. Give us your site hours and access windows and the phasing is planned around them. Most enquiries involve gaps where vanity tops meet the wall and a new bead over an old one coming away, on kitchens and tea points, IPS panels and cubicles and accessible toilets and changing rooms. Whoever orders the work in Gravesend, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
In and around smaller places like Gravesend, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.
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 spell out the cover before we begin.

Honest limits
We check first that sealant really is the fix. It won’t put right:
- Loose panels, vanity units or tiles, which need fixing first
- A dripping waste or valve behind a panel
- Water escaping beneath the floor rather than through a joint
If in doubt, ring 01277 525 020 or send details through our quote form and we will say what we think before you book.
Surfaces we seal
- Urinals and WCs
- Accessible toilets and changing rooms

- IPS panels and cubicles
- Kitchens and tea points
- Vanity units and basins

Busy facilities in and around Gravesend
Gravesend lies roughly 29 miles out from central London, in a commuter belt where offices and business parks are common. Office toilets in the commuter belt are in use from first arrivals to last departures, and resealing in phases keeps facilities available.
At a hospital like Herts and Essex Hospital, which lies south-east of Gravesend, patient and staff washrooms are best done in short phases agreed with the ward. At a school such as Albury Church of England Voluntary Aided Primary School, changing rooms and kitchens need cleanable joints as much as the toilets.

Signs you need washroom sealing in Gravesend
Commercial cleaning is harder on sealant than everyday use. Strong chemicals, scourers and jet washing roughen, discolour or lift a bead so grime sticks to the damaged surface.
Any of the following is a good reason to get the joints checked over:
- Sealant laid over old silicone and now peeling
- Split or peeling sealant at shower trays
- Gaps where vanity tops meet the wall
- Stained sealant around pans and urinals
On an industrial estate such as Hadham Industrial Estate (1.6 miles south of Gravesend), staff toilets, showers and canteens are where sanitary sealant takes the most wear.

Leave it or put it right?
Leaving the job until a shutdown often means living with it for months. With phasing, the work can go ahead while most facilities stay open. For buildings around smaller places like Gravesend, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Looking after the joints
Regular inspection catches problems early. Specifically:
- Keep a record of which washrooms need attention
- Clean sealant with gentle products and a soft cloth
- Keep washrooms out of use until we say the sealant has cured
- Clear standing water from shower floors where possible
Keep extract fans working and vents clear. A room that stays damp will grow mould on almost anything, so get faulty extract looked at.
In food areas, cleanability is something environmental health officers look at. Resealing sinks, worktops and splashbacks before an inspection is a simple step.
Common questions from Gravesend clients
Is hospital work, at somewhere like Herts and Essex Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is Gravesend too far out for you?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Do you take on multi-site work?
Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.
What will the job cost?
Every job gets its own fixed quote. To get one, call the office on 01277 525 020 or email us.
Is it possible to just clean mouldy silicone?
Not for long. Mould grows into the sealant itself, so it comes back however often it’s cleaned. Replacing the bead is the lasting answer.
How long before the toilets can reopen?
Cure times vary by product and temperature. You will get a reopening time for each area before we leave it.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
Cost factors for washrooms and wet areas
Your fixed quote is built from the real scope. It takes account of:
- The product specified
- Induction, permit and paperwork requirements
- Working within restricted access windows
- How much existing material needs removing
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 we will put a fixed figure on it.
Sending details for a quote
A good diagnosis starts with the right details. Let us know:
- The asbestos register, for older buildings
- The site address and postcode
- Anything awkward about access or site hours
- What the building is and how it’s used
Need a figure for a tender or a budget? We’ll quote against your scope and drawings you can plan around. If you have questions first, speak to us on 01277 525 020 or email the details over.
