Remedial sealant for homes and businesses in Lewknor
A movement joint stops working when its sealant splits or sets hard. We cut out the failed sealant and set the depth with backing, then a flexible sealant matched to the movement goes in. If you’re dealing with movement joints that have split or pulled away and black mould underneath the bead, we can help, on expansion joints, leaking tray & enclosure joints and botched or over-sealed joints alike.
Homes around Lewknor are mostly houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. Sealant and grout wear out here just as they do anywhere: old material cut out, joints cleaned and a fresh finish laid.
You’re covered for a year from the day we finish. If anything is not right with it, phone 0345 464 0079 or drop us an email.

Landlord and commercial work in Lewknor
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can be quoted together.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will give you a quote.
How the job changes by surface
Leaking trays & enclosures
A cracked tray, failed valve or leaking waste needs a different fix. We say so rather than reseal.
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.
Common problems we fix in Lewknor
All sealant wears out eventually. Mould grows into the silicone, the surface hardens and the bead shrinks, especially in damp, poorly aired rooms. Then the only fix is removal and a new bead.
Any of these means the joints need attention:
- Over-sealed joints coming away
- Torn expansion joints
- Products that weren’t meant for the joint
- A shower that leaks however often it’s resealed
For site and facilities teams at buildings such as Lewknor Church of England 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.
What to look for in a quote
- Is VAT in the price?
- Are they insured?
- Who turns up on the day
- What product goes in the joint
How to look after the new joints
Aftercare is simple:
- Deal with small splits early
- Do not add new sealant on top of old
- Run the fan after every shower
- Have loose fittings fixed before resealing
If the joint ever needs renewing, have it cut out, not sealed over. Over-sealing is how many remedial jobs start, so the old bead should always come out first.
A failing joint rarely gets better on its own. Every shower or downpour sends more water through, into floors, walls or ceilings. Sorting it early limits the damage.
What affects the cost of remedial sealant
We quote each job individually. These are the things that affect it:
- The old material and how stubborn it is
- The type of sealant required
- The amount of work
- Mould in or behind the old joints
We do not show prices on the website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.
What we need to know
Photos help, but a description is a good start. Please mention:
- The problem you’ve noticed
- If someone has resealed it before
- If it’s domestic, commercial or a hotel
- Where the property is

Do you cover Lewknor for remedial sealant?
Yes, Lewknor is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
Is Lewknor within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
Can tenants book the work?
Yes. Check with your landlord; we can send the quote to them too.
How long before the joint can be used?
It depends on the product and the temperature. We tell you how long to leave it before we go.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access.

Lewknor homes and their sealant
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
For an older house near a landmark such as Church of St Margaret, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

How it works
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. It normally takes a few hours, depending on how many layers have to come out. Somewhere as small as Lewknor, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at how the sealant has failed and check for movement or a leak path.
- We strip the joint completely, removing any layers below.
- The joint is cleaned, treated for mould and left to dry.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- We tool the joint and tell you about anything else that needs attention.
Before we arrive
- Mention any parking rules near the property
- Let us know about earlier repairs to the joints
- Where the joints are inside, avoid wetting them before we arrive
