DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

Aftercare tips
To keep the joints looking good and working properly:
- Encourage users to squeegee shower walls
- Book larger programmes for quieter times of year
- Act on lifting sealant before it leaks
- Use mild cleaners on sealant, not bleach or abrasives
Squeegees in guest and staff showers help: less water sits on the joints between uses.
It’s easier to plan a programme than to react to failures. We can fit the work around bookings, shifts and opening hours, instead of rooms closing without warning.
What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a morning for a small washroom, and a planned programme for bigger sites and we leave things clean and tidy. In a smaller place like Catisfield, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We start with a site walk to agree the rooms and the timing.
- Room by room, we protect the area and remove all the old sealant.
- The joints are degreased, treated and left to dry.
- We lay the right sealant for each area, with anti-fungal silicone in wet rooms.
- We check every room and give its cure time for housekeeping.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about parking restrictions
- Try not to wet indoor joints just before the visit

Why deal with it now?
A quick bead over the old sealant might get a room back in use today, but silicone doesn’t bond to silicone, so it lifts. Doing it properly once is less disruptive than doing it badly twice. Around Catisfield, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, call 0345 464 0079 or send us an email for an honest opinion and a quote.

What commercial sealant looks like in Catisfield
If you run a hotel, guest house or holiday let in a coastal place like Catisfield, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you look after a church, hall or community building such as Church of St Peter, its kitchen and washroom sealant needs looking after like anywhere else. Letting a property close to Fareham station? Then sealant work can be quoted for a single flat or a whole portfolio. If you look after a building such as Ranvilles Infant School, washroom and kitchen sealant can be programmed around term times or opening hours.

Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Will there be a smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
