What we do, step by step
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours for most joints, depending on how much old sealant has to come out. In a small place like High Cross, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- Once dry, a suitable sealant is applied and tooled.
- You get the cure time and our view on why the joint failed.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Tell us if parking is tricky
- Let us know if you’ve seen damp or leaks

About our remedial sealant in High Cross
Remedial jobs in High Cross usually fall into a few patterns: sealant over sealant, mould under the bead, leaks that come back and movement joints that have split. We strip each one back and start from scratch. If you’re dealing with gaps opening along the back of the worktop and repeat leaks from the same joint, we can help, on expansion joints, mouldy bath & shower sealant and failed movement joints alike.
In a village or hamlet like High Cross, homes are often older cottages and farmhouses alongside a few newer houses. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

What the job involves on each surface
Windows & doors
Wrong-coloured or messy mastic can be replaced for appearance too, matched to the frame colour.
Mouldy bath & shower sealant
Mould that has grown into silicone doesn’t clean out for good. The sealant is cut out completely, the joint treated with a mould remover and dried before anti-fungal sanitary silicone goes in.
Landlord and commercial work in High Cross
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Why deal with it now?
Mould under a bead cannot be reached by cleaning. Removal is the only way to get at it, and the joint treated and dried before resealing. In a small place like High Cross, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll go through it with you.

- Failed movement joints
- Expansion joints
- Mouldy bath & shower sealant
Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Keep the room well ventilated
- Act on a lifting corner right away
- Get the cause of a repeat leak found before resealing
- Use a soft cloth, not a scourer, on silicone
Where we’ve pointed out another fault, have it put right, because the new sealant can’t hold back a problem underneath.
Warning signs: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Each one is worth getting looked at.
