Doing it in-house
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Certain joints really need a specialist: 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.
From enquiry to sign-off
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes half a day to a day per washroom, depending on the number of fittings, and our waste is bagged and taken away as we go. Rural sites near Crowmarsh Gifford may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
- A phasing plan keeps part of the building’s facilities in use at all times.
- The failed silicone is stripped and every face scraped clean of residue.
- We clean and dry every surface so the new sealant can grip.
- New sanitary silicone with anti-mould additives goes in and is tooled neat.
- You get a reopening time for every room, with signage left up until then.
Before we start on site
- Send any specification or drawings in advance
- Send your site hours and access windows
- Warn occupants and staff about the work
Getting a fixed quote
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, ring 01277 525 020 or email us.

When something else is needed
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- A dripping waste or valve behind a panel
- Vanity carcasses that have swollen
- Fittings that move too much to hold a bead
If you’re not sure, just phone 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.
What we seal
- Kitchens and tea points
- Accessible toilets and changing rooms
- Urinals and WCs
- Vanity units and basins
- IPS panels and cubicles
- Showers, trays and wet room floors
What we are called out for in Crowmarsh Gifford
Warmth, moisture and soap residue are exactly what mould needs, and silicone joints hold onto all three. Anti-mould additives help, but in a poorly ventilated room mould can still take hold eventually.
Look out for the following:
- Resealing that didn’t last because the old bead stayed
- Failed sealant in a tea point or staff kitchen
- Users noticing mouldy joints
- Failed sealant behind washroom basins
On an industrial estate such as Hithercroft Industrial Estate, which lies west of Crowmarsh Gifford, staff toilets, showers and canteens are where sanitary sealant takes the most wear.
What your quote should include
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Whether primer will be used where the manufacturer specifies it
- How long is the guarantee, and what does it include?
- What site paperwork they can supply
What the job involves on each surface
Urinals and WC pans
Joints around urinals and WC pans take splashes, cleaning chemicals and knocks. Stained or split joints here trap smells and make the room look neglected.
Changing rooms and gyms
Changing rooms can be phased so one stays open. Tell us your site hours and access windows and we’ll plan around them.

Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. The work can go floor by floor, agreed with housekeeping.

Leave it or put it right?
When a washroom looks worn, a refit isn’t the only answer. Where tiles, panels and fittings are sound, new sealant may be enough to put it right while bigger works are planned. Halls, stores and units around places like Crowmarsh Gifford may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a quote when you are ready.

FAQs: Crowmarsh Gifford
Is Crowmarsh Gifford off your patch?
Not at all. Crowmarsh Gifford is within our area. 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 work at healthcare sites like Wallingford Community Hospital?
Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.
What’s the quickest route to a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.
What will the job cost?
Every job gets its own fixed quote. To get one, ring 01277 525 020 or send details through our quote form with a description of the work.
Can you handle several sites?
Yes. A group of buildings can go on one quote, with one point of contact.
Will cleaning remove black mould from sealant?
Cleaning may lighten it, but the mould returns. New anti-mould sanitary silicone is the treatment and point out if ventilation is part of the problem.
Can weather delay the job?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
