How we handle remedial sealant in Brookmans Park
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint won’t last, however tidy it looks. We take it out and use a sealant made for that joint. Typical jobs include torn expansion joints and products that weren’t meant for the joint, on shrunken worktop sealant, botched or over-sealed joints and leaking tray & enclosure joints.
Homes around Brookmans Park are mostly houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. The work is the same as anywhere: everything old comes out before the new sealant or grout goes in.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
What we cannot put right
We will not take on work that will not last, so these are the limits:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- Movement from fittings that are not supported
- Plumbing leaks behind walls or under trays
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly.
Surfaces we seal
- Botched or over-sealed joints
- Expansion joints
- Shrunken worktop sealant
- Failed movement joints
- Mouldy bath & shower sealant
- Leaking tray & enclosure joints
Common problems we fix in Brookmans Park
Some joints fail because water is reaching them from behind. A slow leak behind the tiles soaks the joint from the back, and the sealant lifts or goes mouldy from underneath.
People generally contact us after spotting one of these:
- Sealant that came away because the surface wasn’t prepared
- A shower that leaks however often it’s resealed
- Thick, messy sealant smeared over tiles
- Floor or wall movement joints that have failed
If you live in an older home near United Reformed Church Brookmans Park, older homes can move a little, which is hard on rigid grout and tired sealant.

What happens on the day
You don’t need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the work takes a few hours, depending on how many layers have to come out for a typical job. For a village or hamlet like Brookmans Park, the journey is planned in advance: 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.
- Old beads and residue are removed down to clean surfaces.
- Mould is treated and the joint dried.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you are told about anything else we found.
Getting ready for the visit

Surface by surface
Worktops & kitchens
Kitchen joints often have grease and cleaning residue deep in them, so we spend extra time cleaning before resealing.
Over-sealed & botched joints
Botched joints sometimes have damaged edges from earlier scraping. We work carefully to avoid adding to it, and point out any existing damage.

Why deal with it now?
A joint that has failed twice will fail again unless the cause is dealt with. Taking time to find the cause, whether it’s movement, a leak or the wrong product, is what stops it happening again. Older cottages and farmhouses around Brookmans Park can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.
