About our remedial sealant in Bickley
Remedial work is what we do when sealant has failed or been done badly. New sealant over old, smeared beads, unsuitable products and hidden mould all have to come out. We work on failed movement joints, shrunken worktop sealant and leaking tray & enclosure joints, and people most often call us about movement joints that have split or pulled away and sealant that came away because the surface wasn’t prepared.
In much of London, period terraces have been converted into flats over the years, and bathrooms were often squeezed into small rooms. Small, steamy rooms are where mould gets into sealant and grout fastest, and homes in Bickley are no different.
Your job is guaranteed for a year, as with all our work.

How it works
We keep the work tidy and contained to the area we’re working on. The job usually takes a few hours for a typical bath or shower, longer where several layers have been applied. In Bickley, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us 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.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you are told about anything else we found.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Tell us if parking is tricky
- For business premises, tell us about site rules or sign-in

What happens if it’s left?
Mould under a bead can’t be reached by cleaning. The layers have to come out. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble.
Doing several joints on one visit usually makes better use of the time than several visits. We’ll send you a clear quote for the lot.

DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
What the job involves on each surface
Leaking trays & enclosures
A cracked tray, failed valve or leaking waste needs a different fix. We’ll tell you what we find.
Windows & doors
Frames resealed over the top end up with hard, layered mastic. We remove it all and clean back to sound surfaces.
FAQs for Bickley
Can parking be tricky for a visit in Bickley?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.

Yes. Sealants come in white, clear, grey and other colours, and we agree the colour with you before any work starts.

Quotes for remedial sealant in Bickley
There’s no set price list, because no two jobs are the same. The quote depends on:
- Whether old sealant or filler has to be cut out
- How many areas need sealing
- Which sealant suits the joint
- How easy the joints are to reach
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
What we need to know
What to tell us when you ask for a quote:
- The address or postcode of the job
- How many joints, rooms or windows are involved
- A few pictures by email, if you can
- Access, such as stairs, a lift or height
Quotes start with a quick conversation. Describe the problem, the location and the size of the job. Whenever you’re ready, phone 0345 464 0079 or email us.
Aftercare tips
To keep the joints looking good and working properly:
- Have loose fittings fixed before resealing
- Use a soft cloth, not a scourer, on silicone
- Don’t point over movement joints
- Always have old sealant cut out, not covered
Give the new sealant its full cure time: follow the cure time we give you.
A split movement joint lets rain into walls and floors, and left long enough, the edges of the joint can crumble. A joint with sound edges is far easier to reseal.
Bathrooms and kitchens in Bickley
Bickley has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room. London has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Managing a site like Bullers Wood School for Boys? Then 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. For landlords with property near Bickley station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. Homes close to Church of St George include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them.
