How a job runs
Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For work around Tapnage, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.
- We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
- The phasing is agreed so there are always facilities open.
- We strip out the old bead and clean off the residue left behind.
- Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
- A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
- Rooms reopen after the product’s cure time, and we move to the next.
Before we start on site
- Tell staff and tenants when we’ll be in
- Clear stock, furniture or equipment away from the joints
- Flag any permit to work we will need

Tapnage: questions and answers
Will our hotel in Tapnage need to close for the work?
Almost never. The work is phased so most rooms stay available. The plan is built around your bookings.
Could you schedule work at a campus like Fareham College for the vacation?
Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Is Tapnage in your area?
Yes. Sites across Tapnage are covered, with one number for every area we cover.
Do you take on small jobs?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Does the weather affect the work?
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. Inside work is seldom held up.
Do your applicators hold CSCS cards?
Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.
What affects the price in Tapnage
To price the job, we consider:
- Phasing around occupants
- Backing rod, priming and other preparation
- How accessible the joints are
- Whether old sealant has to be cut out first
What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a quote once you have the details.
What to include in your enquiry
For an accurate fixed quote, we need a clear picture of the site. Send us:
- Rough lengths or quantities, or drawings if you have them
- Photos of the joints, close up and from further back
- Any dates the work must fit around
- Whether an asbestos survey exists
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.
Aftercare for building managers
To get the most from the new sealant:
- Photograph and log failed joints across the estate
- Act on the first split you see at a shower tray
- Don’t leave trays and floors sitting wet
- Inspect washroom sealant regularly
Ask your cleaning team to use gentle products and soft cloths on sealant. Aggressive descalers, solvents and scouring pads shorten its life over time.
In food areas, cleanability is something environmental health officers look at. Resealing sinks, worktops and splashbacks before an inspection is a simple step.
Different surfaces, different methods
Wet-room floors and floor-to-wall joints
Wet floors are common in accessible showers and changing rooms so the edges are checked carefully.
Urinals and WC pans
Floor joints around WC pans are often forgotten. They are checked with everything else.
Leave it or put it right?
Gaps and mould in joints give dirt and bacteria somewhere to sit, and in kitchens, clinics and schools that is a real concern. Sound, smooth joints are much easier to keep clean. Halls, stores and units around places like Tapnage may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
