Remedial sealant in Chalk Farm, done properly
Two decades of sealant work means we recognise most failures quickly. We’re ARBOMaster approved and fully insured, and every remedial job comes with a 12-month guarantee. We work on mouldy bath & shower sealant, failed movement joints and shrunken worktop sealant, and the jobs we see most are caulk or the wrong sealant used in a wet area and mould trapped under a layer of silicone.
Much of London’s older housing is Victorian and Edwardian terraces, many of them now split into flats, with bathrooms fitted into whatever space was available. A compact bathroom that steams up every day is hard on silicone and grout.
Whatever the size of the job, you get the same 12-month guarantee.

Aftercare tips
So the new joints stay in good condition:
- Air the bathroom so the sealant can dry
- Deal with small splits early
- Find out why the sealant failed first
- Look for stains below bathrooms now and then
Ventilation keeps mould away from the new bead: run the fan during and after showers, or open a window.
A split movement joint lets rain into walls and floors, and the longer it’s left, the more the joint edges break down. A joint with sound edges is far easier to reseal.
Work for landlords, hotels and businesses
Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll quote.
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Leave it or put it right?
Repeat failures have a cause. Taking time to find the cause, whether it’s movement, a leak or the wrong product, is what stops it happening again. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and agree the price before starting.
What you get with us

What we do, step by step
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a typical bath or shower, longer where several layers have been applied. For a job in Chalk Farm, parking and access are the things to plan: let us know about parking, the floor we will be working on and any lift or shared entrance.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- Once dry, a suitable sealant is applied and tooled.
- You get the cure time and our view on why the joint failed.
Getting ready for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention any sign-in or site rules at work premises
- Mention any tricky access

Bathrooms and kitchens in Chalk Farm
There are hotels and other places to stay in and around Chalk Farm. Hotel bathrooms are part of our work as well as homes, and can be done room by room. 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.
If you look after a building such as Haverstock School, we reseal washrooms and kitchens in schools and businesses as well as homes. Chalk Farm is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
Chalk Farm is about 1 mile south-east of Hampstead, in Greater London. Chalk Farm gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. Chalk Farm is one of 764 places in Greater London where we work for remedial sealant.
Work in NW5, NW1 and NW3 is quoted and booked the same way as anywhere else. You’ll find streets such as Eton Road, Oval Road and Regal Lane.

Common problems we fix in Chalk Farm
A lot of failed joints have been sealed over rather than replaced. Silicone doesn’t bond to silicone, so the top layer lifts and water and mould collect between the two.
Look out for any of the following:
- Thick, messy sealant smeared over tiles
- Black mould underneath the bead
- Over-sealed joints coming away
- Leaks that keep coming back after resealing
For an older house near a landmark such as St Silas Church, older homes can move a little, which is hard on rigid grout and tired sealant.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Sealing over old silicone is the commonest DIY error. 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.

Your questions about remedial sealant in Chalk Farm
I live in a flat in Chalk Farm. Can a failed seal leak into the flat below?
It can, yes: water that gets past a split bead or cracked grout often runs under the tray and shows on the ceiling below. It’s far simpler to replace tired sealant early than to deal with a neighbour’s ceiling.
Is parking a problem for a job in Chalk Farm?
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.
Someone sealed over the old bead. Can you fix it?
Yes. We cut out all the layers and clean off the film, before resealing with a single bead.
Can you remove old sealant without damaging the bath?
Yes. Careful removal is most of a remedial job, particularly on softer surfaces like acrylic.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Can landlords and businesses book you?
Yes, we do. We work in homes, commercial premises and hotels.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
My shower still leaks after a reseal. Can you sort it?
Yes. We check it’s the sealant and not the tray, valve or waste, then strip and reseal the joints.
