About our remedial sealant in Upper Norwood
Movement and expansion joints fail when the sealant cannot stretch. The old sealant comes out and backing goes in to control the depth, then a flexible sealant matched to the movement goes in. We’re often asked to deal with gaps opening along the back of the worktop and mould trapped under a layer of silicone, on leaking tray & enclosure joints, expansion joints and failed movement joints.
Much of London’s older housing is Victorian and Edwardian terraces, many of them now split into flats, with bathrooms fitted into whatever space was available. Small, steamy rooms are where mould gets into sealant and grout fastest.

What affects the cost of remedial sealant
You’ll get a clear quote before work begins. It takes into account:
- Access and height
- Whether old sealant or filler has to be cut out
- Which sealant suits the joint
- The number and length of the joints
Doing several joints on one visit is normally more efficient than separate visits. You will get one clear quote for the whole job.
Asking for a quote
There’s no need for technical detail. Just tell us:
- Access, such as stairs, a lift or height
- The problem you’ve noticed
- How many joints, rooms or windows are involved
- Whether it’s a home or a business

Why act early in Upper Norwood
Stripping out botched sealant adds time to a reseal, but not by much: it takes a few hours for most joints, depending on how much old sealant has to come out. Compared with chasing the same leak every few months, it’s time well spent. In a flat in Upper Norwood, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.

What sealant work can’t fix
New sealant can’t fix everything, and we’d rather say so up front. It will not solve:
- Cracks in the fitting rather than the joint
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Water damage behind tiles that needs a tiler
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think.
Joints and surfaces we work on
- Expansion joints
- Shrunken worktop sealant
- Mouldy bath & shower sealant
- Failed movement joints
- Botched or over-sealed joints
- Leaking tray & enclosure joints
DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Surface by surface
Mouldy bath & shower sealant
Black mould inside the bead will not scrub out. All of it comes out, and the joint is treated and dried ahead of a new anti-fungal bead.
Movement & expansion joints
Movement joints in floors, walls and façades need a flexible sealant set to the right depth. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed with a low-modulus product.

The process
On the day, we start by going over the job with you, so you know exactly what we are doing. Surfaces next to the work are protected before any work begins. The work generally takes a few hours for most joints, depending on how much old sealant has to come out. In Upper Norwood, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Each layer is cut out and the residue cleaned off.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you’re told about anything else we found.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Move anything stored near the joints
- Let us know about stairs, lifts or work at height

Upper Norwood homes and their sealant
London’s water is hard, so limescale builds up on sealant, grout and fittings. In a London flat, water from a failed bath or shower seal can reach the neighbours below, which is why it’s worth fixing early.
Homes close to Christ Church include some older properties, and walls and floors in older homes can move, and sealant and grout show it first. As a London address, Upper Norwood can be tricky for parking: let us know about parking bays, permits or a driveway. If you let a flat or house near Gipsy Hill station, botched sealant from a previous quick fix is easier to strip out between tenants.
