- Gaps opening along the back of the worktop
- Mould trapped under a layer of silicone
- Decorators’ caulk around a bath or shower
Common problems we fix in Cross Gate
How a joint is built matters as much as the product. A bead bonded on three sides, or laid too thick, cannot flex, and tears at the first real movement. Backing sets the depth and stops that.
Common reasons people contact us include:
- Dark patches showing through the sealant
- Kitchen joints letting water behind the worktop
- Movement joints that have split or pulled away
- Wide, uneven beads that look worse than the old ones
If you live in an older home near The Parish Church of St Michael and All Angels, older homes can move a little, which is hard on rigid grout and tired sealant.

About our remedial sealant in Cross Gate
A joint that keeps letting you down needs more than another bead. It helps to have photos when you ring 0345 464 0079 or email us, and say how long ago it was last done. If you’re dealing with dark patches showing through the sealant and movement joints that have split or pulled away, we can put it right, whatever the surface.
For a small place like Cross Gate, remedial sealant is planned like any other job: the journey and access are simply agreed in advance. Once we are there, the bathroom or kitchen gets the same care as anywhere else.
A one-year guarantee comes as standard.

How we quote for remedial sealant
We do not publish a price list, because jobs vary so much. The quote depends on:
- How many areas need sealing
- Whether there’s mould to deal with
- How easy the joints are to reach
- The number and length of the joints
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, call 0345 464 0079 or drop us an email for an honest opinion and a quote.
What we need to know
You don’t need to know the technical terms. It helps if you can tell us:
- How we’d reach the joints
- Where the job is, and your postcode
- Any previous sealing or DIY work
- Photos by email, if that is easy
Getting a quote is simple: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we will take it from there.

What happens if it’s left?
Hidden water does the most damage: wet floors, stained ceilings and swollen worktops. Dealing with the joint now is a small job by comparison. Older cottages and farmhouses around Cross Gate can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Cross Gate homes and their sealant
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.

DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
How it 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 and we leave things clean and tidy. For a village or hamlet like Cross Gate, 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.
- We protect the surfaces around the joint.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- New sealant goes in once the joint is dry, and is tooled smooth.
- You get the cure time and our view on why the joint failed.
How to prepare
- Move anything stored near the joints
- Let us know about parking restrictions
- Tell us about access, such as stairs, a lift or high-level joints
