DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Why act early in Trotton Marsh
Leaks that are left keep doing damage out of sight: soaked floorboards, ceiling stains below and blown plaster. Dealing with the joint now is a small job by comparison. Older cottages and farmhouses around Trotton Marsh can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Aftercare tips
To keep the joints looking good and working properly:
- Get the cause of a repeat leak found before resealing
- Keep bleach and abrasives off the bead
- Do not add new sealant on top of old
- Air the bathroom so the sealant can dry
Do not let anyone seal over it later. New silicone does not bond to old, so the old bead should always come out first.
Mould under a second layer of sealant keeps growing out of sight. When it finally shows, the whole bead needs to come out.

If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Surrounding tiles, trays and frames are protected first.
- The botched or failed sealant is cut away completely.
- We clean and degrease the joint and look for signs of movement or water.
- New sealant goes in once the joint is dry, and is tooled smooth.
- We give you the cure time and explain what caused the failure.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any previous sealing or DIY attempts
- Tell us if parking is tricky

Signs you need remedial sealant in Trotton Marsh
One of the commonest remedial jobs is sealant on top of sealant. New silicone can’t stick to the old bead, so the top layer lifts and water and mould collect between the two.
The most common problems we see are:
- Sealant that came away because the surface wasn’t prepared
- Gaps opening along the back of the worktop
- Repeat leaks from the same joint
- Floor or wall movement joints that have failed
Letting a property close to Liphook station? Then a joint that keeps failing is best fixed properly while the property is empty.
What your quote should include

- What the cure time is
- Which sealant they’ll use, and why
- Is VAT in the price?
