How we handle remedial sealant in Brent Cross
A movement joint stops working when its sealant splits or sets hard. The old sealant comes out and backing goes in to control the depth, before resealing with a flexible product suited to the movement. We work on botched or over-sealed joints, expansion joints and shrunken worktop sealant, and the jobs we see most are gaps opening along the back of the worktop and thick, messy sealant smeared over tiles.
In much of London, period terraces have been converted into flats over the years, and bathrooms were often squeezed into small rooms. Small, steamy rooms are where mould gets into sealant and grout fastest.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Bathrooms and kitchens in Brent Cross
Brent Cross has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room. London has hard water, which leaves limescale on sealant, grout and taps.
As a London address, Brent Cross can be tricky for parking: let us know about parking bays, permits or a driveway. Rented homes near Brent Cross West station change hands often, and a joint that keeps failing is best fixed properly while the property is empty. For an older house near a landmark such as Christ Church Hendon, walls and floors in older homes can move, and sealant and grout show it first.

Why deal with it now?
Adding more sealant is the usual quick fix, and it rarely works. It cannot bond to what’s underneath, leaving the leak in place and one more layer to cut out later. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Brent Cross, the repair is bigger than a sealant job.
Combining jobs into one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will give you a clear price for the lot.

Questions from Brent Cross
Can worn sealant in a flat in Brent Cross cause a leak downstairs?
Yes, and the first sign is often a stain on the ceiling below. Cutting out the old sealant and laying a new bead early stops it getting that far.
Do you work in hotels near Brent Cross?
Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Do you guarantee remedial jobs?
Yes, for 12 months. If we have pointed out another problem, getting it fixed helps the new joint last.
What do you need from me for a quote?
A short description and the location, plus photos if you have them. If we need more, we’ll ask.
Where are you based?
Our base is in Crawley, and we work across South East England, London and Scotland.
Someone sealed over the old bead. Can you fix it?
Yes. Each layer is cut out and the residue cleaned off, before resealing with a single bead.
Can tenants book the work?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all.
Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
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.
What sealant work cannot fix
We’d rather tell you now than do work that will not last, so these are the limits:
- A cracked shower tray or bath (that needs repair or replacing)
- Older mastics that may need an asbestos check before removal
- Plumbing leaks behind walls or under trays
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think.
Surfaces we seal
- Failed movement joints
- Expansion joints
- Botched or over-sealed joints
- Leaking tray & enclosure joints
- Mouldy bath & shower sealant
- Shrunken worktop sealant
Different surfaces, different methods
Worktops & kitchens
Old kitchen sealant pulls back from the wall over time. We strip it, degrease the joint and reseal in a colour to suit.
Mouldy bath & shower sealant
Repeat mould normally points to a damp, poorly aired room. Along with resealing, we’ll mention if the room needs better ventilation.
Aftercare tips
To keep the joints looking good and working properly:
- Don’t add new sealant on top of old
- Run the fan after every shower
- Clean sealant with mild products only
- Report a tray that rocks or a worktop that lifts
Keep the room ventilated: use the extractor or open a window after showering.
A failing joint rarely gets better on its own. Every shower or downpour sends more water through, into floors, walls or ceilings. Early action keeps it to a sealant job.
