When to call us in South Bersted
Even good sealant ages. Mould grows into the silicone, the surface hardens and the bead shrinks, especially in damp, poorly aired rooms. At that point it has to come out.
Signs it’s time to call us include:
- Wide, uneven beads that look worse than the old ones
- Beads that never stuck properly
- Repeat leaks from the same joint
- Movement joints that have split or pulled away
Rented homes near Bognor Regis station change hands often, and a joint that keeps failing is best fixed properly while the property is empty.

How it works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for most joints, depending on how much old sealant has to come out and we leave things clean and tidy. For a job in South Bersted, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First we work out whether the problem is the sealant, movement or a leak.
- Each layer is cut out and the residue cleaned off.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Let us know about parking restrictions
- Tell us about access, such as stairs, a lift or high-level joints

Aftercare tips
A little care helps the new joints last. We recommend:
- Ask why a joint failed before redoing it
- Keep movement joints clear of mortar and paint
- Air the bathroom so the sealant can dry
- Keep an eye on the ceiling below the bathroom
Clean gently: no scraping, scouring pads or harsh chemicals.
Mould under a second layer of sealant keeps growing out of sight. When it finally shows, the whole bead needs to come out.

DIY versus a professional finish
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.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What the job involves on each surface
Movement & expansion joints
Some movement joints have been filled with mortar or grout. Where it can be raked out, we replace it with flexible sealant.
Leaking trays & enclosures
Where the joints are the problem, every bead is stripped and resealed with anti-fungal sanitary silicone, tray edges and screen profiles included.

Common questions in South Bersted
Is South Bersted within the area you cover?

Do you take on hotel work around South Bersted?
Yes. Hotel and guest-house work is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Someone sealed over the old bead. Can you fix it?
Yes. It’s slower than a standard reseal, because every layer has to come out cleanly, but it’s the only way the new joint will last.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will explain our choice.
Can you fix a reseal that hasn’t worked?
Yes. There’s usually a reason: sealant over sealant, movement or another leak, and we deal with the cause first.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
