When something else is needed
We will always be straight with you, so here’s what sealant can’t fix:
- A tray or worktop that needs refixing first
- Older mastics that may need an asbestos check before removal
- Failed tanking or loose tiles behind the sealant
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think.
Joints and surfaces we work on
- Mouldy bath & shower sealant
- Shrunken worktop sealant

- Botched or over-sealed joints
Remedial sealant for homes and businesses in Little Dunmow
If a joint has been resealed and is leaking again, it’s worth a proper look. Send photos when you call 0345 464 0079 or drop us an email. Common call-outs are for decorators’ caulk around a bath or shower and smears and lumps from a botched reseal, across leaking tray & enclosure joints, expansion joints and botched or over-sealed joints.
Even in a smaller place like Little Dunmow, bathrooms and kitchens see heavy daily use. Older or newer, every room gets the same approach: old sealant or grout cut out, joints cleaned and dried, and a fresh finish laid.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
When to call us in Little Dunmow
All sealant wears out eventually. Mould grows into the silicone, the surface hardens and the bead shrinks. Then the only fix is removal and a new bead.
People normally contact us after spotting one of these:
- Dark patches showing through the sealant
- Decorators’ caulk around a bath or shower
- Torn expansion joints
- Gaps opening along the back of the worktop
If you live in an older home near Church of St Mary the Virgin, older homes can move a little, which is hard on rigid grout and tired sealant.

How the job changes by surface
Windows & doors
Frames resealed over the top end up with hard, layered mastic. We remove it all and clean back to sound surfaces before backing and resealing.
Movement & expansion joints
Bonding on three sides is a common reason movement joints tear. Backing stops that, letting the sealant flex between the two faces.

Why act early in Little Dunmow
Mould under a bead can’t be reached by cleaning. Removal is the only way to get at it. Homes in smaller places like Little Dunmow can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.

How the visit works
You don’t need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes a few hours for a typical bath or shower, longer where several layers have been applied in most cases. Parking around Little Dunmow is normally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- Surrounding tiles, trays and frames are protected first.
- The botched or failed sealant is cut away completely.
- We clean and degrease the joint and look for signs of movement or water.
- Once dry, a suitable sealant is applied and tooled.
- We give you the cure time and explain what caused the failure.
