Remedial sealant in Tapnage, done properly
Not every leak is a sealant leak. A cracked tray, a failed shower valve or a leaking waste can look just the same. If that’s what we find, we’ll tell you rather than reseal something that will not fix it. Common call-outs are for torn expansion joints and a shower that leaks however often it’s resealed, on expansion joints, leaking tray & enclosure joints and shrunken worktop sealant.
Somewhere as small as Tapnage, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
Every job is covered by our one-year guarantee, wherever you are in Hampshire.

The process
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours for a typical bath or shower, longer where several layers have been applied. For a village or hamlet like Tapnage, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking the joint for movement, leaks and the reason it failed.
- Every layer of old sealant is cut and cleaned out.
- We clean the joint, treat any mould and let it dry.
- Moving joints get backing and a flexible sealant to suit.
- The new joint is tooled neatly and we explain anything else we found.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Let us know if you’ve seen damp or leaks

How we quote for remedial sealant
The price is agreed before any work begins. It’s based on:
- Any mould that needs treating
- Which sealant suits the joint
- The number and length of the joints
- Working hours on commercial sites
Combining jobs into one visit is normally more efficient than separate visits. You will get one clear quote for the whole job.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- The problem you’ve noticed
- The type of property
- How many joints, rooms or windows are involved
- Pictures of the joints, sent by email
Getting a quote is simple: let us know what needs doing and where. Photos by email help us understand the job, and we’ll come back to you with a quote.
DIY versus a professional finish
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Bathrooms and kitchens in Tapnage
Tapnage has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room. Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
If you let a flat or house near Swanwick station, a joint that keeps failing is best fixed properly while the property is empty.

Why deal with it now?
Leaks that are left keep doing damage out of sight: wet floors, stained ceilings and swollen worktops. Dealing with the joint now is a small job by comparison. Where a wall is exposed, as many are in small places like Tapnage, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.

We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Do you need remedial sealant in Tapnage?
A lot of failed joints have been sealed over rather than replaced. New silicone cannot stick to the old bead, so the new layer peels, and damp and mould settle between them.
Signs it’s time to call us include:
- Over-sealed joints coming away
- Dark patches showing through the sealant
- Leaks that keep coming back after resealing
- Beads that never stuck properly
Schools such as The Henry Cort Community College are buildings too, and washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.
Questions to ask before you book
- Whether they’re fully insured
- How hidden problems are handled
- When the joint can take water or movement
- Is VAT in the price?
