Bathroom & kitchen resealing in Forest Hill, Greater London
Professional bathroom resealing in and around Forest Hill, with every bit of old sealant taken out first and a 12-month guarantee.
- Water getting behind the kitchen upstand
- Gaps where the bath or tray has moved
- Lumpy, uneven sealant from a DIY attempt
Common problems we fix in Forest Hill
Older sealant shrinks and hardens. Along worktops it tends to pull back from the wall, opening a hairline gap that lets water and crumbs in. Hot pans and harsh cleaners do not help.
Look out for these signs:
- A joint torn by a bath that flexes
- Leaks into the floor or ceiling below
- Mouldy sealant that has gone black
- Leaking joints on a shower screen
In the older streets around Honor Oak Christian Fellowship Centre, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Bathroom resealing in Forest Hill, done properly
With over 20 years in the trade, we reseal baths, showers and kitchens in homes across Forest Hill. We are fully insured ARBOMaster approved applicators, and the work comes with a 12-month guarantee. If you’re dealing with water getting behind the kitchen upstand and a messy, uneven bead from a previous reseal, we can help, whatever the surface.
London homes include a lot of flats, conversions and mansion blocks, so a bathroom is often directly above a neighbour’s ceiling. In Forest Hill, that is a good reason to put tired sealant and grout right early.
You get a one-year guarantee, the same in Forest Hill as everywhere else we work.

What bathroom resealing looks like in Forest Hill
London’s water is hard, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in. 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.
If you look after a building such as Fairlawn Primary School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes. Forest Hill is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Honest limits
We will not take on work that won’t last, so here’s what sealant cannot put right:
- A cracked shower tray or bath (that needs repair or replacement)
- A bath or tray that moves because it is not properly supported
- Water coming from the plumbing rather than the joint
If in doubt, ring 0345 464 0079 or email us and we will say what we think.
Joints and surfaces we work on
- Kitchen worktops & upstands
- Basins & vanity units
- Baths
- Sinks & splashbacks
- Shower trays & enclosures
- Wet rooms
Why it’s worth doing now in Forest Hill
Mould removers can fade the surface of a stained bead, but mould that has grown into the sealant tends to return. The lasting answer is to remove the bead and start again. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Forest Hill, the repair is bigger than the sealant job would have been.
Combining jobs into one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

What we do, step by step
On the day, there’s very little for you to do. 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 Forest Hill, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- 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.
- Any bath is filled with water, then we lay a bead of anti-fungal silicone in white, clear or a matching colour.
- We finish the joint, clear up and tell you how long to leave it before it gets wet.
Before we arrive
- Let us know about parking restrictions
- Mention any tricky access
- Tell us about any previous sealing or DIY attempts
Getting a quote
Asking for a quote is easy: let us know what needs doing and where and its rough size. A few pictures by email make the job easier to understand.

Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
If you do try it yourself, take your time over the 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.
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Clean with a mild bathroom cleaner and a soft cloth
- Give the silicone its full cure time
- Never pick at the silicone with a blade
- Run the extractor fan during and after every shower
Mould needs damp, so keep the room aired. 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. Replacing the sealant early keeps the job small.
For landlords and businesses
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we are fully insured.

Questions from Forest Hill
Is parking a problem for a job in Forest Hill?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Could a tired shower seal in my Forest Hill flat affect the neighbours below?
Yes. In a flat, water from a failed bath or shower seal has only one way to go, and that is down. A proper reseal before the leak starts is the easy fix.
Can I choose the colour of the sealant?
White, clear and a range of colours are available. On a worktop we colour-match where the joint shows.
What information do you need?
A short description and the location. We’ll ask anything else we need to know.
Do you work for letting agents?
Yes, often. Several properties can be quoted together, and between tenancies is a good time for the work.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us, and we are fully insured.
Can you just seal over the old silicone?
No. It’s a common reason for reseals failing. The old joint is stripped, cleaned and resealed from scratch.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures.
