Landlords, agents and businesses in Colney Street
We work for landlords and letting agents as well as householders. Sealant work between tenants is a simple way to keep a property in good order.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can go on one quote.
What the job involves on each surface
Over-sealed & botched joints
A thick bead smeared across tiles often hides mould or gaps. We strip it back so we can see the joint, and then we reseal it neatly.
Movement & expansion joints
Joints filled with mortar, grout or rigid filler cannot move. We rake that out where it can be removed and seal with a flexible product.
What we can’t put right
A few problems are outside what sealant work can do:
- A tray or bath that’s cracked
- Movement from fittings that aren’t supported
- Older mastics that may need an asbestos check before removal
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly before you book.
Where we work in Colney Street
- Mouldy bath & shower sealant
- Failed movement joints
- Shrunken worktop sealant
- Botched or over-sealed joints
- Expansion joints
- Leaking tray & enclosure joints
Leave it or put it right?
Spraying mould remover on a sealed-over joint doesn’t reach what’s underneath. The layers have to come out, and the joint treated and dried before resealing. Older cottages and farmhouses around Colney Street can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote.

Common problems we fix in Colney Street
Some joints fail because water is reaching them from behind. A leaking valve, a failed waste or cracked grout feeds water behind the bead, so the silicone goes mouldy or lets go.
Signs it’s time to call us include:
- Leaks that keep coming back after resealing
- Wide, uneven beads that look worse than the old ones
- Torn expansion joints
- Sealant peeling off a dusty or damp surface
If you live in an older home near Church of the Holy Trinity, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.
