Remedial sealant in Netley Marsh
Remedial work is what we do when sealant has failed or been done badly. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all need stripping out before the joint can be done properly. If you have mould trapped under a layer of silicone and a shower that leaks however often it’s resealed, we can help.
In a village or hamlet like Netley Marsh, homes are often older cottages and farmhouses alongside a few newer houses. Movement in older walls and floors tends to show first as cracked grout or split sealant.
Big or small, you get the same 12-month guarantee in Netley Marsh and across Hampshire.

When to call us in Netley Marsh
Products get mixed up: acrylic caulk in a wet area, a general-purpose sealant on a moving joint, or an acetoxy silicone on natural stone or some metals. None of them last.
The most common problems we see are:
- Thick, messy sealant smeared over tiles
- Repeat leaks from the same joint
- Movement joints that have split or pulled away
- Sealant applied over old sealant that has lifted
Schools such as Netley Marsh Church of England Infant School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Surface by surface
Windows & doors
Failed frame mastic is often hard, cracked and in several layers. We remove it all and clean back to sound surfaces before backing and resealing.
Worktops & kitchens
Kitchen joints hold grease and residue, so we spend extra time cleaning.
Netley Marsh homes and their sealant
Netley Marsh is within about 3 miles of the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, and sealant and grout that work that hard wear out sooner. Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.
Homes close to Church of St Matthew include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them. If you let a flat or house near Ashurst New Forest station, botched sealant from a previous quick fix is easier to strip out between tenants.

What happens on the day
When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work starts. Most jobs take a few hours, depending on how many layers have to come out. Somewhere like Netley Marsh needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First we find out how and where the joint has failed.
- We strip the joint completely, removing any layers below.
- Next, any mould is treated and the joint dried.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- The new joint is tooled neatly and we explain anything else we found.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Where the joints are inside, avoid wetting them before we arrive
- Plan for the work area to be out of bounds to pets and children

Advice
When it is not the sealant
Before you book, it’s worth knowing the limits too:
- Tiles that have come away from the wall
- Cracks in the fitting rather than the joint
- A bath, tray or worktop that moves until it’s properly fixed
If you are not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer.
What we seal
- Mouldy bath & shower sealant
- Failed movement joints
- Botched or over-sealed joints
- Leaking tray & enclosure joints
- Expansion joints
- Shrunken worktop sealant
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Why it’s worth doing now in Netley Marsh
Remedial work takes longer than a straight reseal, but not by much: the work takes a few hours for a typical bath or shower, longer where several layers have been applied. It’s far less disruption than resealing the same joint again and again. Where a wall is exposed, as many are in small places like Netley Marsh, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.
