- Loose or hollow tiles, or failed tanking behind them

FAQs for Lower Assendon
Do you work in hotels near Lower Assendon?
Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.
I let a flat near Henley-On-Thames station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can go on one quote. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear quote.
What does bathroom resealing cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Do you guarantee your resealing?
Yes. Every job carries our 12-month guarantee.
How long before the new sealant can get wet?
Silicone is touch-dry quite quickly, but it takes longer to cure. Keep water off it for around 24 hours, or follow the cure time we give you.
Can you get rid of the black mould in my sealant?
Yes, we replace the mouldy bead. Sprays can fade the marks, but cutting it out and resealing is what lasts. Airing the room well helps stop it returning.
Do you take out the old sealant first?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
Can you reseal around my kitchen sink and worktop?
Yes, often alongside a bathroom. Where it’s needed by the sink, we use a food-safe sealant.

From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Do you need bathroom resealing in Lower Assendon?
Plenty of failed sealant has been laid over the top of older sealant. Fresh silicone can’t grip the old bead underneath, so it lifts, lets water in and traps mould underneath.
Common reasons people contact us are:
- A reseal done over the top of the old bead
- A messy, uneven bead from a previous reseal
- Water getting behind the bath panel
- Mouldy sealant that has gone black
In the older streets around Church of St Anne, walls and floors in older homes can move, and sealant and grout show it first.

How it works
On the day, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before work begins. Most jobs take half a day or less for one room, longer when the kitchen is included. Somewhere as small as Lower Assendon, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First the area is protected and every bit of old sealant removed.
- Next, the joint is cleaned and any mould is treated.
- We let it dry fully and fill the bath with water before sealing.
- A single bead of anti-fungal sanitary silicone is applied and tooled smooth.
- We tidy up and give you the cure time, normally around 24 hours.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Mention if the joints have been sealed before
- Mention any tricky access

Why act early in Lower Assendon
A failed joint gets more costly to put right the longer it’s left. Once water is behind the bath, it can reach floorboards, panels and the ceiling underneath, turning a small job into a building repair. Around Lower Assendon, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.

Surface by surface
Wet rooms
In a wet room, the joints between floor and walls take standing water. They get anti-fungal sanitary silicone, and our work is on the visible joints only.
Baths
Baths move more than any other fitting, so we fill it with water before sealing. That way the joint is laid with the bath at its heaviest and isn’t stretched when it’s used.
How to look after the new joints
After the cure time, these simple habits help:
- Let new sealant cure fully before it gets wet
- Open a window or run the fan so the room dries
- Squeegee the walls and tray after use
- Clean with a mild bathroom cleaner and a soft cloth
Check the sealant now and then. Small splits and lifting ends are easy to catch early, and if anything looks wrong, just call 0345 464 0079 or send us an email.
Worktop joints fail quietly. Water gets behind the upstand and into the edge of a laminate worktop, and the board underneath can swell. Resealing before that happens protects the worktop.
