About our remedial sealant in New Addington
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint won’t last, however tidy it looks. Out it comes, and in goes a sealant suited to the job. If you’re dealing with floor or wall movement joints that have failed and decorators’ caulk around a bath or shower, we can put it right, on leaking tray & enclosure joints, expansion joints and failed movement joints alike.
London homes include a lot of flats, conversions and mansion blocks, and many bathrooms sit right above someone else’s ceiling. That makes worn sealant and cracked grout in New Addington more than a cosmetic job.
All our work is covered by a 12-month guarantee.

What we are called out for in New Addington
Water from somewhere else can ruin a good seal. A slow leak behind the tiles soaks the joint from the back, and the sealant lifts or goes mouldy from underneath.
These are the problems we’re asked about most:
- Thick, messy sealant smeared over tiles
- Over-sealed joints coming away
- Floor or wall movement joints that have failed
- Worktop sealant that has shrunk and split
If you live in an older home near St Edward King and Confessor, walls and floors in older homes can move, and sealant and grout show it first.
Before booking anyone
- Which colour the sealant will be
- Whether the sealant suits the joint
- What happens if the job turns out different
- Whether all the old sealant comes out first
What happens if it’s left?
A failed seal rarely means a new bathroom. When the fittings are sound, stripping and resealing the joints is often enough. Where something else has failed, you’ll hear it from us. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in New Addington, the repair is bigger than a sealant job.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or email us.

How the visit works
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes a few hours, depending on how many layers have to come out. In New Addington, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- 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.
- New sealant goes in once the joint is dry, and is tooled smooth.
- We give you the cure time and explain what caused the failure.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Let us know about stairs, lifts or work at height
- Clear items away from the joints we are working on

Remedial sealant in New Addington: local notes
In a London flat, water from a failed bath or shower seal can reach the neighbours below, so tired sealant is best dealt with early. London has hard water, so limescale builds up on sealant, grout and fittings.
If you look after a building such as Rowdown Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. New Addington is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

What affects the cost of remedial sealant
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The old material and how stubborn it is
- When we can work, for business premises
- The number of rooms or windows
- Whether the work is at height
The cost depends on how much there is to do, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts.

How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Air the bathroom so the sealant can dry
- Report a tray that rocks or a worktop that lifts
- Keep an eye on the ceiling below the bathroom
- Use a soft cloth, not a scourer, on silicone
Clean gently: a mild cleaner and a soft cloth, with no blades or scourers.
Movement joints that have split let water into the structure, and the longer it’s left, the more the joint edges break down. A joint with sound edges is far easier to reseal.
Different surfaces, different methods
Leaking trays & enclosures
A shower that leaks after resealing often has a tray that moves or an enclosure sealed on the wrong side. Both are checked before we reseal.
Windows & doors
Frames resealed over the top end up with hard, layered mastic. All of it is cut out and the frame and wall cleaned.
Questions from New Addington
Can parking be tricky for a visit in New Addington?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
I live in a flat in New Addington. Can a failed seal leak into the flat below?
Yes, and the first sign is often a stain on the ceiling below. A proper reseal before the leak starts is the easy fix.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Are you insured?
Yes. Full insurance covers our work.
Do you work for hotels and businesses?
Yes. Larger jobs can be planned room by room or area by area.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Do you fix expansion and movement joints?
Yes. Where mortar or filler has been used instead of sealant, it’s removed where it can be, and reseal with a flexible product.
