Bathroom & kitchen resealing in Northwood, Greater London
Baths, showers and worktops in Northwood need attention? We cut out the old, prepare the joints and apply the right sealant, with a one-year guarantee.
- Smears of silicone across the tiles
- Failed sealant on the screen profile
- Black mould in the silicone that will not clean off
Bathroom resealing for homes and businesses in Northwood
Showers work their sealant harder than baths. Tray edges, screen profiles and wet room joints all rely on silicone to stay watertight. Each gets a bead of anti-fungal sanitary silicone, tooled smooth so water runs off instead of sitting in a ridge. If you have leaks into the floor or ceiling below and cracked, shrunken or lifting silicone, we can put it right, on sinks & splashbacks, baths and kitchen worktops & upstands alike.
London homes include a lot of flats, conversions and mansion blocks, so a bathroom is often directly above a neighbour’s ceiling. In Northwood, that’s a good reason to put tired sealant and grout right early.
All of our work is guaranteed for twelve months.

When to call us in Northwood
Older sealant shrinks and hardens. In kitchens it often shrinks away from the back edge, opening a hairline gap that lets water and crumbs in. Hot pans and harsh cleaners don’t help.
People normally contact us when they notice something like this:
- A joint torn by a bath that flexes
- Water getting behind the kitchen upstand
- Smears of silicone across the tiles
- Failed sealant on the screen profile
Schools such as Frithwood Primary School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
What your quote should include
- Is VAT in the price?
- Is the old sealant removed completely?
- How long to leave it before use
- How much experience the applicator has

Bathroom resealing in Northwood: local notes
London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, which is why it’s worth fixing early. London has hard water, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in.
In the older streets around Emmanuel Church, walls and floors in older homes can move, and sealant and grout show it first. Northwood is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Northwood questions
Is parking an issue for bathroom resealing in Northwood?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
I let a flat near Carpenders Park station. Can you help?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
How long before the new sealant can get wet?
After around 24 hours in most cases. We’ll tell you the cure time for the product we used.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
Can you reseal around my kitchen sink and worktop?
Yes. The old sealant is cut out and the joint degreased, because cooking grease stops silicone sticking, then a colour-matched bead is laid.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
What we can’t put right
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Water coming from the plumbing rather than the joint
- A bath or tray that moves because it is not properly supported
- Loose or hollow tiles, or failed tanking behind them
If in doubt, call 0345 464 0079 or email us and we will say what we think.
Where we work in Northwood
- Shower trays & enclosures
- Basins & vanity units
- Baths
- Wet rooms
- Sinks & splashbacks
- Kitchen worktops & upstands
Looking after it afterwards
A little care helps the new joints last. Our advice:
- Wipe up water along the back of the worktop
- Avoid abrasive pads on the sealant
- Keep the fan on for a while after bathing
- Wait for the cure time we give you
Good ventilation does more than any cleaner. Run the extractor fan during and after a shower, so the bead dries out between uses.
Mould that starts as a few spots spreads through the bead. When it has grown right through, it rarely cleans out, and nearby grout often goes the same way. Catching it early keeps it a simple reseal.
What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a couple of hours for one bath or shower, or most of a day for a full bathroom and kitchen, and the area is left clean. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- 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.
- The joint is cleaned, degreased and treated for mould.
- With the joint dry, and any bath loaded with water, a single bead of anti-fungal silicone is applied.
- We tool the bead to a neat finish and give you the cure time, normally around 24 hours.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Plan for the work area to be out of bounds to pets and children
- Mention if the joints have been sealed before

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
