West Leith Remedial Sealant
Failed sealant joints in West Leith need attention? We cut out the old, prepare the joints and apply the right sealant.

Remedial sealant in West Leith
A movement joint stops working when its sealant splits or sets hard. The old sealant comes out and backing goes in to control the depth, then a flexible sealant matched to the movement goes in. We work on shrunken worktop sealant, failed movement joints and botched or over-sealed joints, and people most often call us about leaks that keep coming back after resealing and smears and lumps from a botched reseal.
Somewhere as small as West Leith, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
You get a 12-month guarantee, the same in West Leith as everywhere else we work.

What sealant work can’t fix
We won’t take on work that won’t last, so these are the limits:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- A tray or bath that’s cracked
- Plumbing leaks behind walls or under trays
If you are not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer.
Joints and surfaces we work on
- Failed movement joints
- Mouldy bath & shower sealant
- Shrunken worktop sealant
- Leaking tray & enclosure joints
- Botched or over-sealed joints
- Expansion joints
DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
What happens on the day
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we have agreed what’s being done, we protect the area and start. Most jobs take a few hours for a typical bath or shower, longer where several layers have been applied. For a village or hamlet like West Leith, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First we find out how and where the joint has failed.
- We strip the joint completely, removing any layers below.
- The joint is cleaned, treated for mould and left to dry.
- Moving joints get backing and a flexible sealant to suit.
- The new joint is tooled neatly and we explain anything else we found.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Let us know about earlier repairs to the joints
- Keep pets and children clear of the area while we work

- When we can work, for business premises
- Whether the work is at height
- Any mould that needs treating
- How many areas need sealing
The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.

Different surfaces, different methods
Worktops & kitchens
Kitchen joints often have grease and cleaning residue deep in them, so cleaning takes longer than in a bathroom before resealing.
Over-sealed & botched joints
A botched joint can hide two or three layers of sealant, and silicone residue is cleaned off the tiles too. New sealant needs a fully clean surface.
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Always have old sealant cut out, not covered
- Clean sealant with mild products only
- Do not wait for a small gap to become a leak
- Ask why a joint failed before redoing it
Leave the new joint to cure fully before it gets wet or moves: follow the cure time we give you.
Leaks through failed sealant grow over time. Every shower or downpour sends more water through, into whatever is behind or below. Sorting it early limits the damage.
Why deal with it now?
Stripping out botched sealant adds time to a reseal, but not by much: it takes a few hours for most joints, depending on how much old sealant has to come out. Compared with chasing the same leak every few months, it’s time well spent. Older cottages and farmhouses around West Leith can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

West Leith homes and their sealant
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Letting a property close to Tring station? Then a joint that keeps failing is best fixed properly while the property is empty. For an older house near a landmark such as Church of St Martha (Anglian Methodist), bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. Schools such as Goldfield Infants' and Nursery School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.
