Remedial Sealant in Navestock Heath
We cover Navestock Heath for removing failed, mouldy or leaking sealant and putting it right. Old sealant removed completely, joints prepared properly.
- Smears and lumps from a botched reseal
- Mould trapped under a layer of silicone
- A second bead peeling off the first
Leave it or put it right?
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. Older cottages and farmhouses around Navestock Heath can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.
Why us?
- An ARBOMaster approved applicator
- Homes, businesses and hotels
- Anti-fungal sanitary silicone in wet areas
- You choose the colour before work begins

About our remedial sealant in Navestock Heath
A joint that keeps failing usually has a reason. Movement, the wrong product or a leak from somewhere else will beat any new bead. Finding that cause comes before any new sealant. We work on failed movement joints, mouldy bath & shower sealant and botched or over-sealed joints, and common reasons people get in touch are sealant that came away because the surface wasn’t prepared and wide, uneven beads that look worse than the old ones.
Homes around Navestock Heath are mostly houses and cottages rather than flats. The work is the same as anywhere: everything old comes out before the new sealant or grout goes in.
There’s a 12-month guarantee on every job, large or small.

When to call us in Navestock Heath
A lot of failed joints have been sealed over rather than replaced. New silicone cannot stick to the old bead, so the top layer lifts and water and mould collect between the two.
It’s worth asking for a quote if you see:
- Leaks that keep coming back after resealing
- Movement joints that have split or pulled away
- Kitchen joints letting water behind the worktop
- Products that weren’t meant for the joint
For landlords with property near Harold Wood station, botched sealant from a previous quick fix is easier to strip out between tenants.

Navestock Heath homes and their sealant
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
For an older house near a landmark such as Church of St Thomas the Apostle, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Never seal over old silicone
- Look for stains below bathrooms now and then
- Do not wait for a small gap to become a leak
- Keep the room well ventilated
Give the new sealant its full cure time: usually around 24 hours, or as long as we advise.
Do not keep resealing the same joint. Get the cause found first, otherwise the next attempt will fail too.
How the visit works
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the work takes a few hours for most joints, depending on how much old sealant has to come out in most cases. Somewhere like Navestock Heath needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we work out whether the problem is the sealant, movement or a leak.
- Each layer is cut out and the residue cleaned off.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- We finish neatly and point out anything that needs another trade.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Mention any parking rules near the property
- Mention if the joints have been sealed before

For landlords and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
How the job changes by surface
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. Once it’s all removed, the joint is treated.
Leaking trays & enclosures
Repeat shower leaks often come from a tray that flexes or an enclosure sealed in the wrong place. Both are checked before any new sealant goes on.
