Remedial sealant in Greatness

Why deal with it now?
Adding more sealant is the usual quick fix, and it rarely works. It can’t bond to what’s underneath, so the leak carries on and there’s now more to remove. In an older home around Greatness, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
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.

Greatness homes and their sealant
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Schools such as St John's Church of England Primary School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes. For landlords with property near Bat & Ball station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

What affects the cost of remedial sealant
Call for a quick quote. The main things that affect it are:
- Which sealant suits the joint
- The number of rooms or windows
- How much there is to do
- Any mould that needs treating
Combining jobs into one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
What we need to know
Photos by email are helpful but not essential. Try to tell us:
- Photos by email, if that’s easy
- What the problem is, such as mould, gaps, leaks or cracking
- Where the property is
- How we’d reach the joints
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
When something else is needed
We’ll always be straight with you, so here’s what sealant cannot fix:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- Failed tanking or loose tiles behind the sealant
- A bath, tray or worktop that moves until it’s properly fixed
If you are not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer.
Surfaces we seal
- Expansion joints
- Mouldy bath & shower sealant
- Botched or over-sealed joints
- Shrunken worktop sealant
- Leaking tray & enclosure joints
- Failed movement joints

When to call us in Greatness
Joints that move need sealant that can stretch. Flexing baths, rocking trays and building movement joints will split a rigid or thin bead.
Look out for these signs:
- Torn expansion joints
- Repeat leaks from the same joint
- Gaps opening along the back of the worktop
- Wide, uneven beads that look worse than the old ones
If you live in an older home near St John the Baptist, older homes can move a little, which is hard on rigid grout and tired sealant.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Never fill a movement joint with mortar or grout
- Always have old sealant cut out, not covered
- Report a tray that rocks or a worktop that lifts
- Find out why the sealant failed first
Give the new sealant its full cure time: usually around 24 hours, or as long as we advise.
A split movement joint lets rain into walls and floors, and left long enough, the edges of the joint can crumble. Resealing while the edges are sound is simpler.
How the job changes by surface
Worktops & kitchens
If a worktop moves when you lean on it, the sealant will keep splitting. It needs fixing down first, and we’ll tell you if we find it.
Leaking trays & enclosures
A cracked tray, failed valve or leaking waste needs a different fix. We say so rather than reseal.
How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a typical bath or shower, longer where several layers have been applied, and the area is left clean. For a job in Greatness, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First we work out whether the problem is the sealant, movement or a leak.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
Preparing for the visit
- Move anything stored near the joints
- Let us know about stairs, lifts or work at height
- Mention if the joints have been sealed before
