Remedial sealant in Martins Heron
Some sealant jobs are not a simple reseal, because someone has already had a go. 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. We’re often asked to deal with repeat leaks from the same joint and smears and lumps from a botched reseal, on mouldy bath & shower sealant, leaking tray & enclosure joints and shrunken worktop sealant.
Around Martins Heron, you’ll mostly find houses and bungalows, some older and some much newer. Sealant and grout wear out here just as they do in a big town.
Big or small, you get the same one-year guarantee.

How the job changes 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.
Movement & expansion joints
Some movement joints have been filled with mortar or grout. We rake that out where it can be removed and seal with a flexible product.
Remedial sealant in Martins Heron: local notes
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. Martins Heron is part of Bracknell, one of the post-war new towns. With many homes dating from the post-war decades, plenty of bathrooms have been resealed or refitted more than once. New sealant will not stick to old, so the old layers have to come out first.
For an older house near a landmark such as St Paul, walls and floors in older homes can move, and sealant and grout show it first. If you look after a building such as Harmans Water Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes.

Martins Heron: your questions answered
Do older homes in Martins Heron need their sealant replacing?
In most cases, yes, if it hasn’t been done for a while. Sealant doesn’t last for ever, and its life depends on use, cleaning and weather, and many homes in Martins Heron may already be on their second or third set.
Will you come out to Martins Heron?
Yes. Martins Heron is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
Do you work for landlords and businesses?
Yes. Domestic, commercial and hotel work are all part of what we do.
Can you reseal a split movement joint?
Yes. Where mortar or filler has been used instead of sealant, it’s removed where it can be, and reseal with a flexible product.
My shower still leaks after a reseal. Can you sort it?
Yes. There’s usually a reason: sealant over sealant, movement or another leak, so we find that first.
Can you remove old sealant without damaging the bath?
Yes. Careful removal is most of a remedial job, particularly on softer surfaces like acrylic.
Do you guarantee remedial jobs?
Yes. You get our 12-month guarantee.
Do you need remedial sealant in Martins Heron?
Joint depth matters. Sealant packed too deep, or stuck to the back of the joint as well as the sides, can’t stretch, and tears at the first real movement. Backing rod or bond-breaker tape prevents it.
These are the problems we are asked about most:
- Kitchen joints letting water behind the worktop
- Over-sealed joints coming away
- Floor or wall movement joints that have failed
- Thick, messy sealant smeared over tiles
For landlords with property near Martins Heron station, botched sealant from a previous quick fix is easier to strip out between tenants.
Comparing quotes
- Whether they seal over old material or remove it
- How long to leave it before use
- How the joint is cleaned and prepared
- What product goes in the joint
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Keep bleach and abrasives off the bead
- Report a tray that rocks or a worktop that lifts
- Ask why a joint failed before redoing it
- Look for stains below bathrooms now and then
Do not let anyone seal over it later. Over-sealing is how many remedial jobs start, so the old bead should always come out first.
Movement joints that have split let water into the structure, and the longer it’s left, the more the joint edges break down. A joint with sound edges is far easier to reseal.
How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours, depending on how many layers have to come out. For a job in Martins Heron, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Each layer is cut out and the residue cleaned off.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
Preparing for the visit
- Mention any tricky access
- Mention any parking rules near the property
- On commercial sites, let us know about site rules
