How we handle remedial sealant in West Heath
The wrong product in the wrong joint won’t last, however tidy it looks. We take it out and use a sealant made for that joint. If you are dealing with mould trapped under a layer of silicone and sealant that came away because the surface wasn’t prepared, we can help, on leaking tray & enclosure joints, failed movement joints and mouldy bath & shower sealant alike.
In much of London, period terraces have been converted into flats over the years, and bathrooms were often squeezed into small rooms. A compact bathroom that steams up every day is hard on silicone and grout, and homes in West Heath are no different.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What we are called out for in West Heath
Silicone only bonds to surfaces that are clean and dry. Soap film, dust, damp or old residue stop it gripping, and the joint starts to come away early.
Any of these means the joints need attention:
- Repeat leaks from the same joint
- Smears and lumps from a botched reseal
- Mould trapped under a layer of silicone
- A second bead peeling off the first
If you let a flat or house near Abbey Wood station, a joint that keeps failing is best fixed properly while the property is empty.

Why deal with it now?
It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and any film left behind stops new sealant sticking. Careful stripping is where most of our time goes. 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.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, call 0345 464 0079 or email us and we will give you an honest view and a quote.

What remedial sealant looks like in West Heath
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. London has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
West Heath is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. If you live in an older home near St Andrew's, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

The process
Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a typical bath or shower, longer where several layers have been applied. In a London area like West Heath, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.
- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- We clean and degrease the joint and look for signs of movement or water.
- Once dry, a suitable sealant is applied and tooled.
- We give you the cure time and explain what caused the failure.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Let us know about stairs, lifts or work at height
- Move anything stored near the joints

Advice
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Clean sealant with mild products only
- Look for stains below bathrooms now and then
- Air the bathroom so the sealant can dry
- Don’t add new sealant on top of old
If the joint ever needs renewing, have it cut out, not sealed over. Over-sealing is how many remedial jobs start, so the old bead should always come out first.
A failing joint rarely gets better on its own. Every shower or downpour sends more water through, into floors, walls or ceilings. Sorting it early limits the damage.
What the job involves on each surface
Mouldy bath & shower sealant
Repeat mould generally points to a damp, poorly aired room. Along with resealing, we will mention if the room needs better ventilation.
Movement & expansion joints
A movement joint must be able to stretch. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed.
Questions from West Heath
I let a flat near Abbey Wood station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
Can worn sealant in a flat in West Heath cause a leak downstairs?
Yes. In a flat, water from a failed bath or shower seal has only one way to go, and that’s down. A proper reseal before the leak starts is the easy fix.
Do you offer different sealant colours?
We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.
Someone resealed my shower and it’s leaking again. Can you help?
Yes. There’s normally a reason: sealant over sealant, movement or another leak, and we deal with the cause first.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us, and we are fully insured.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Do you cover West Heath?
Yes, we do. Our applicators work in West Heath, and the service is the same as everywhere else.
