How we handle bathroom resealing in Foxbury
Resealing is a small job that makes a big difference. Mouldy silicone makes even a new bathroom look neglected, and a clean white or clear joint fixes it quickly. Just as important, it closes the gaps water would otherwise get through. Typical jobs include gaps where the bath or tray has moved and water escaping at the shower enclosure, on shower trays & enclosures, kitchen worktops & upstands and wet rooms.
London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. In Foxbury, bathroom resealing is as much about a room looking cared for as about keeping water out.
All our work comes with a 12-month guarantee.

Questions from Foxbury
Can you help a landlord with a rental near Sidcup station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
Can parking be tricky for a visit in Foxbury?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Do you work for hotels and businesses?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Do you do kitchens as well as bathrooms?
Yes. The old sealant is cut out and the joint degreased, because cooking grease stops silicone sticking, then we reseal in a colour to suit.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or send us an email.
Are you insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and we will quote it together.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
What bathroom resealing looks like in Foxbury
London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, so tired sealant is best dealt with early. London has hard water, so limescale builds up on sealant, grout and fittings.
As a London address, Foxbury can be tricky for parking: let us know about parking bays, permits or a driveway. Managing a site like Chislehurst School for Girls? Then we reseal washrooms and kitchens in schools and businesses as well as homes.

Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Looking after it afterwards
So the new joints stay in good condition:
- Look for lifting corners and small gaps now and then
- Avoid abrasive pads on the sealant
- Open a window or run the fan so the room dries
- Use gentle cleaners on the silicone
Have a look at the joints every few months. Small splits and lifting ends are easy to catch early, so if something does not look right, just ring 0345 464 0079 or drop us an email.
Small signs come before a leak: lifting ends, gaps, dark shadows under the bead or a stain downstairs. Any of these means the joint needs attention.
What affects the cost of bathroom resealing
The price is agreed before any work begins. It’s based on:
- Access and height
- The old material and how stubborn it is
- How many areas need sealing
- Any mould that needs treating
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
Helping us quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- How many joints, rooms or windows are involved
- Whether it has been sealed before
- What the problem is, such as mould, gaps, leaks or cracking
- If it’s domestic, commercial or a hotel

How it works
We keep the work tidy and contained to the area we’re working on, so you can get on with your day. The job generally takes a couple of hours for one bath or shower, or most of a day for a full bathroom and kitchen, and we explain the cure time before we leave. In a London area like Foxbury, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- Protection goes down around the bath, shower or worktop.
- Old sealant is sliced away and the residue removed.
- We treat any mould and let the joint dry properly.
- Baths are filled first, then anti-fungal sanitary silicone is applied in a colour to suit.
- The joint is finished neatly and we explain when it can get wet.
Getting ready for the visit
- Keep children and pets away from the work area
- Let us know about earlier repairs to the joints
- Clear the area around the work

Related advice
When to call us in Foxbury
The wrong product fails fast. Decorators’ caulk and all-purpose sealants aren’t made for constant wetting, so they stain, crack or go mouldy before long. Wet areas call for a sanitary silicone with an anti-fungal additive.
If you can see any of these, it’s time to have the joints looked at:
- Gaps where the bath or tray has moved
- Smears of silicone across the tiles
- Leaks into the floor or ceiling below
- Mouldy sealant that has gone black
In the older streets around Christ Church, older homes can move a little, which is hard on rigid grout and tired sealant.
What your quote should include
- Is VAT in the price?
- The length of the guarantee
- Who does the work, and how experienced they are
- When the joint can take water or movement
For landlords and businesses
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Leave it or put it right?
Leaving a split or mouldy bead only stores up trouble. Water that gets behind a bath soaks into the floor, the panel and sometimes the ceiling below, turning a small job into a building repair. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in Foxbury.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.
