How we handle bathroom resealing in Northwick Park
Showers work their sealant harder than baths. Tray edges, screen profiles and wet room joints all rely on silicone to stay watertight. They’re resealed with anti-fungal sanitary silicone, finished smooth so water drains away rather than collecting. Common call-outs are for a joint torn by a bath that flexes and failed sealant on the screen profile, on kitchen worktops & upstands, baths and wet rooms.
Across London, a large share of homes are flats, conversions or mansion blocks, and many bathrooms sit right above someone else’s ceiling. In Northwick Park, that is a good reason to put tired sealant and grout right early.
We stand behind the work with a one-year guarantee.

What happens if it’s left?
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, and that is a far bigger job than a reseal. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, ring 0345 464 0079 or send us an email and we will give you an honest view and a quote.

The process
There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes a morning or an afternoon for most single baths and showers, including the tidy-up. In a London area like Northwick Park, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.
- First, each joint is checked for movement and signs of water.
- Every trace of the old bead is removed, including the thin smear on the tiles.
- Joints are degreased and any mould is treated.
- When the joint is dry, and a bath has been filled with water, the new silicone goes on.
- We tool the bead to a neat finish and give you the cure time, normally around 24 hours.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Mention if the joints have been sealed before
- Plan for the work area to be out of bounds to pets and children

When to call us in Northwick Park
Baths and trays move. Acrylic in particular gives slightly under the weight of water and a person, and a tray that is not fully bedded can rock. That movement works at the bead until it splits or peels away.
Any of these means the joints need attention:
- Cracked, shrunken or lifting silicone
- Two layers of silicone, both failing
- Gaps between the worktop and the wall
- A joint torn by a bath that flexes
For landlords with property near Kenton station, mouldy sealant is one of the first things a new tenant notices, so it’s worth renewing between lets.

Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Northwick Park questions
Is parking an issue for bathroom resealing in Northwick Park?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
I let a flat near Kenton station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Is white the only colour available?
You’re not limited to white: clear, white and colours chosen to suit the room. We will talk it through when we quote.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
Quotes for bathroom resealing in Northwick Park
Jobs vary more than people expect. The main factors:
- The type of sealant required
- Any working-time requirements on site
- The size of the job
- Whether there’s mould to deal with
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Helping us quote
When you call or email, it’s useful to know:
- The address or postcode of the job

- Roughly how big the job is
Every job is quoted individually, so start by telling us what you need. Simply call 0345 464 0079 or drop us an email and describe the job.
Looking after it afterwards
So the new joints stay in good condition:
- Open a window or run the fan so the room dries
- Keep an eye on the corners, where splits start
- Wipe up water along the back of the worktop
- Let new sealant cure fully before it gets wet
Mould needs damp, so keep the room aired. Use the fan, or open a window, while you bathe and for a while afterwards, so the bead dries out between uses.
Worktop joints fail quietly. Splashes run behind the back edge and soak into the worktop, and the board underneath can swell. A reseal in time can save the worktop.
What the job involves on each surface
Sinks & splashbacks
Water getting under the rim of an inset sink can soak the worktop. Where the sealant around the visible edge has failed, we renew it.
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.
Bathrooms and kitchens in Northwick Park
In a London flat, water from a failed bath or shower seal can reach the neighbours below, so tired sealant is best dealt with early. London has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Homes close to Saint Cuthberts Church include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant. As a London address, Northwick Park can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
