What else we do in Northbourne
Common problems we fix in Northbourne
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.
Any of these means the joints need attention:
- Products that weren’t meant for the joint
- Sealant that came away because the surface wasn’t prepared
- Sealant applied over old sealant that has lifted
- Mould trapped under a layer of silicone
Letting a property close to Walmer station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

- Whether VAT is included
- How long to leave it before use
- How the joint is cleaned and prepared
What we do, step by step
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and clear up. Most jobs take a few hours for most joints, depending on how much old sealant has to come out. Somewhere as small as Northbourne, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- 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
- Let us know about earlier repairs to the joints
- Plan for the work area to be out of bounds to pets and children
- Mention any sign-in or site rules at work premises

Advice
How the job changes by surface
Leaking trays & enclosures
Repeat shower leaks often come from a tray that flexes or an enclosure sealed in the wrong place. We check both before any new sealant goes on.
Movement & expansion joints
Some movement joints have been filled with mortar or grout. Where it can be raked out, we replace it with flexible sealant.
Why act early in Northbourne
Spraying mould remover on a sealed-over joint does not reach what’s underneath. The layers have to come out, and the joint treated and dried before resealing. Where a wall is exposed, as many are in small places like Northbourne, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What it costs depends on the amount of work, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts.
Why choose Mr Mastic in Northbourne

Remedial sealant in Northbourne: local notes
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.
Homes close to Church of St Augustine include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant. If you look after a building such as Northbourne Church of England Primary School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.
