How we quote for remedial sealant
Every job gets its own quote. This is what makes a difference:
- Whether old sealant or filler has to be cut out
- When we can work, for business premises
- How easy the joints are to reach
- Any mould that needs treating
The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.
Asking for a quote
Photos help, but a description is a good start. Please mention:
- Access, such as stairs, a lift or height
- How many joints, rooms or windows are involved
- If someone has resealed it before
- What the problem is, such as mould, gaps, leaks or cracking
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that is easy.
Remedial sealant in Addington
Removing failed sealant is the hardest part of the job. Every layer is cut out, the residue cleaned off and the joint degreased, taking care not to scratch the surfaces around it. Only then can new sealant bond. We work on mouldy bath & shower sealant, expansion joints and shrunken worktop sealant, and common reasons people get in touch are torn expansion joints and mould trapped under a layer of silicone.
For a small place like Addington, remedial sealant is planned like any other job: it just means planning the journey and access beforehand. Once we are there, the bathroom or kitchen gets the same care as anywhere else.
Every job comes with our one-year guarantee.

Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How it works
Most of a good job is in the preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours, depending on how many layers have to come out. Somewhere as small as Addington, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at how the sealant has failed and check for movement or a leak path.
- All the old sealant comes out, including any layers underneath.
- Next, any mould is treated and the joint dried.
- We use the right backing and sealant for any joint that moves.
- We tool the joint and tell you about anything else that needs attention.
How to prepare
- Let us know about stairs, lifts or work at height
- Keep children and pets away from the work area
- Tell us about any water getting in

Remedial sealant in Addington: local notes
Addington has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room. Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you look after a building such as Offham 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.

Addington questions
Will you come out to Addington?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you work in hotels near Addington?
Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
What if the leak is not the sealant?
Then we explain what we have found. A plumber or fitter may be needed before any new sealant goes on.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Can you fix a reseal that hasn’t worked?
Yes. All the sealant comes out, we find out why it failed, and the joint is resealed properly.
What does remedial sealant cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before we start.
Common problems we fix in Addington
A lot of failed joints have been sealed over rather than replaced. New silicone cannot stick to the old bead, so the top layer lifts and water and mould collect between the two.
The most common problems we see are:
- Mould trapped under a layer of silicone
- Wide, uneven beads that look worse than the old ones
- Sealant applied over old sealant that has lifted
- Gaps opening along the back of the worktop
Homes close to Church of St Margaret include some older properties, and walls and floors in older homes can move, and sealant and grout show it first.
Questions to ask before you book
- Which sealant they’ll use, and why
- Is the old sealant removed completely?
- What preparation is included
- What the cure time is

What else we do in Addington
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Report a tray that rocks or a worktop that lifts
- Run the fan after every shower
- Use a soft cloth, not a scourer, on silicone
- Keep an eye on the ceiling below the bathroom
Keep the room ventilated: run the fan during and after showers, or open a window.
Signs to act on: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Each one is worth getting looked at.
