Remedial sealant in Bexley Riverside, done properly
A movement joint stops working when its sealant splits or sets hard. The old sealant comes out and backing goes in to control the depth, then a flexible sealant matched to the movement goes in. If you have a second bead peeling off the first and dark patches showing through the sealant, we can help.
Much of London’s older housing is Victorian and Edwardian terraces, many of them now split into flats, and bathrooms were often squeezed into small rooms. Small, steamy rooms are where mould gets into sealant and grout fastest.
Whatever the size of the job, it’s backed by our one-year guarantee in Bexley Riverside and across Greater London.

When to call us in Bexley Riverside
Even good sealant ages. Over the years it shrinks, hardens and gets colonised by mould, faster where ventilation is poor. Then the only fix is removal and a new bead.
Most people get in touch when they notice something like this:
- Worktop sealant that has shrunk and split
- Products that weren’t meant for the joint
- Mould trapped under a layer of silicone
- Thick, messy sealant smeared over tiles
If you let a flat or house near Barnehurst station, botched sealant from a previous quick fix is easier to strip out between tenants.
Before you book anyone
- What happens if the job turns out different
- Whether the sealant suits the joint
- What preparation is included
- Is VAT in the price?
What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a typical bath or shower, longer where several layers have been applied, and the area is left clean. In Bexley Riverside, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- The joint is degreased and checked for movement and leaks.
- Once dry, a suitable sealant is applied and tooled.
- 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
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any previous sealing or DIY attempts

Bexley Riverside homes and their sealant
London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, so tired sealant is best dealt with early. 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.
As a London address, Bexley Riverside can be tricky for parking: let us know about parking bays, permits or a driveway. For site and facilities teams at buildings such as Normandy Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes.

When it isn’t the sealant
Sealant isn’t the answer to every problem, and we’d rather say so up front. It won’t solve:
- A leaking trap, valve or supply pipe
- A bath, tray or worktop that moves until it’s properly fixed
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
If you’re not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer before booking.
Surfaces we seal

Other services in Bexley Riverside
Work for landlords, hotels and businesses
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Hotels need rooms back in use, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
Aftercare tips
Aftercare is simple, and it makes a real difference:
- Always have old sealant cut out, not covered
- Keep the room well ventilated
- Have loose fittings fixed before resealing
- Keep bleach and abrasives off the bead
If we’ve found a cause, such as a loose tray or a leaking waste, get it fixed, because the new sealant cannot hold back a problem underneath.
Leaks through failed sealant grow over time. Each use pushes more water behind the bead, into whatever is behind or below. Sorting it early limits the damage.
Questions from Bexley Riverside
I live in a flat in Bexley Riverside. Can a failed seal leak into the flat below?
Yes. In a flat, water from a failed bath or shower seal has only one way to go, and that’s down. A proper reseal before the leak starts is the easy fix.
Is parking an issue for remedial sealant in Bexley Riverside?
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.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
How long does the work take?
The number of joints and layers decides it. We’ll tell you before any work starts.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Do you work in Bexley Riverside?
Yes. We work in Bexley Riverside. To book, phone 0345 464 0079 or drop us an email.
What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
What affects the quote in Bexley Riverside
Some jobs are bigger than they look, and some smaller. The main factors:
- Access and height
- Working hours on commercial sites
- The old material and how stubborn it is
- Mould in or behind the old joints
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
What we need to know
Before you ask for a quote, have a think about:
- If it’s domestic, commercial or a hotel
- Where the job is, and your postcode
- Any access issues, like height or stairs
- Photos by email, if that is easy
Getting a quote is simple: tell us what needs doing and where. A few photos by email make the job easier to understand.
Different surfaces, different methods
Movement & expansion joints
A movement joint must be able to stretch. We remove the failed sealant, fit backing and reseal.
Mouldy bath & shower sealant
Where mould keeps coming back, ventilation is normally part of the cause. Along with resealing, we will mention if the room needs better ventilation.
