What happens on the day
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for most joints, depending on how much old sealant has to come out. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Heston. It helps if you can point us to a visitor permit or a bay close to the door.
- We look at how the sealant has failed and check for movement or a leak path.
- We strip the joint completely, removing any layers below.
- We clean the joint, treat any mould and let it dry.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- Finally we finish the joint and talk you through what we found.

About our remedial sealant in Heston
If a joint has been resealed and is leaking again, it’s worth a proper look. Send photos when you call 0345 464 0079 or drop us an email. We work on failed movement joints, leaking tray & enclosure joints and expansion joints, and people most often call us about wide, uneven beads that look worse than the old ones and sealant peeling off a dusty or damp surface.
Hard London water leaves limescale on sealant, grout and taps alike. For a bathroom or kitchen in Heston, getting the joints right keeps water where it belongs and the room looking clean.
The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or drop us an email.

What we’re called out for in Heston
All sealant wears out eventually. Mould grows into the silicone, the surface hardens and the bead shrinks, especially in damp, poorly aired rooms. Then the only fix is removal and a new bead.
Look out for these signs:
- Mould trapped under a layer of silicone
- Torn expansion joints
- Thick, messy sealant smeared over tiles
- Decorators’ caulk around a bath or shower
Schools such as Westbrook Primary School are buildings too, and 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.
Questions to ask before booking
- Whether VAT is included
- How long the guarantee is
- What happens if the job turns out different
- How the surfaces are prepared before sealing
Leave it or put it right?
Hidden water does the most damage: wet floors, stained ceilings and swollen worktops. Dealing with the joint now is a small job by comparison. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in Heston.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.

Questions from Heston
Is parking a problem for a job in Heston?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
Do you take on hotel work around Heston?
Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.
Can you remove old sealant without damaging the bath?
Yes. Careful removal is most of a remedial job, particularly on softer surfaces like acrylic.
How long will it take to strip and reseal the joint?
Allow a few hours for a typical bath or shower, longer where several layers have been applied. We’ll give you a timescale when we quote.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
How do I get a quote for remedial sealant in Heston?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Is remedial work guaranteed?
Yes. Our 12-month guarantee covers the work, and we are fully insured.
Do you fix expansion and movement joints?
Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.

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. Everything old must be removed first.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Heston homes and their sealant
Heston has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room. London has hard water, so limescale builds up on sealant, grout and fittings.
As a London address, Heston can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. Homes close to St Leonard's Church include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant.

What the job involves on each surface

Old kitchen sealant pulls back from the wall over time. It’s cut out, degreased and resealed.
Windows & doors
Smeared or badly matched mastic can be cut out and redone neatly, matched to the frame colour.
Landlords, agents and businesses in Heston
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
