Remedial sealant & repairs in Oldbury, Kent
Professional remedial sealant in and around Oldbury, with every bit of old sealant taken out first and a 12-month guarantee.
- Floor or wall movement joints that have failed
- Smears and lumps from a botched reseal
- Gaps opening along the back of the worktop
Why deal with it now?
Adding more sealant is the usual quick fix, and it rarely works. It cannot bond to what’s underneath, leaving the leak in place and one more layer to cut out later. Where a wall is exposed, as many are in small places like Oldbury, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Remedial sealant in Oldbury, done properly
Water on the floor doesn’t always mean failed silicone. A cracked tray, a failed shower valve or a leaking waste can look just the same. When the fault is elsewhere, we say so instead of resealing for the sake of it. Common call-outs are for a shower that leaks however often it’s resealed and products that weren’t meant for the joint, on failed movement joints, mouldy bath & shower sealant and leaking tray & enclosure joints.
For a small place like Oldbury, remedial sealant is planned like any other job: the journey and access are simply agreed in advance. In the bathroom or kitchen, the work is the same as in any town.
Each job carries a 12-month guarantee, whatever its size.

Your questions about remedial sealant in Oldbury
Is Oldbury in your area for remedial sealant?
Yes. Our work covers London and the South East, and Oldbury is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.
Is Oldbury within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we are done.
Can you reseal a split movement joint?
Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Are you fully insured?

Where are you based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Can you quote for more than one area?
Of course. Doing several areas at once is normally more efficient.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Ask why a joint failed before redoing it
- Run the fan after every shower
- Use a soft cloth, not a scourer, on silicone
- Have loose fittings fixed before resealing
Keep an eye on the joint at first, particularly where the original failure was caused by movement. Should anything change, ring 0345 464 0079 or send us an email.
A failing joint rarely gets better on its own. Every shower or downpour sends more water through, into whatever is behind or below. Early action keeps it to a sealant job.
Bathrooms and kitchens in Oldbury
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 Peter, timber floors under older bathrooms flex, so joints need a sealant that moves with them. Letting a property close to Borough Green & Wrotham station? Then botched sealant from a previous quick fix is easier to strip out between tenants.

What’s near Oldbury
In Oldbury, that means homes and buildings near The Old House, Ivy Hatch Nature Reserve and Wrotham School, among other places. The closest station to Oldbury is Borough Green & Wrotham station, roughly 1.4 miles north-east. Nearby you will also find Beechin Wood Archery Museum (2.4 miles east) and Ightham Court (0.8 miles north-east).
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What affects the cost of remedial sealant
Your quote is based on your job. We look at:
- The product the joint needs
- The number and length of the joints
- How many areas need sealing
- Whether the work is at height
Doing several joints on one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We will send you a clear quote for the lot.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- A few pictures by email, if you can
- How many joints, rooms or windows are involved
- If someone has resealed it before
- If it’s domestic, commercial or a hotel
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is. Whenever you’re ready, call 0345 464 0079 or email us.

What happens on the day
At the end, we look at the finished work together and explain the cure time. The visit itself generally takes a few hours for most joints, depending on how much old sealant has to come out, depending on the amount of work. Somewhere as small as Oldbury, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- The right product goes in, with backing where the joint moves.
- We finish neatly and point out anything that needs another trade.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Let us know if you’ve seen damp or leaks
- For indoor joints, keep the area dry beforehand if you can

What we are called out for in Oldbury
Using the wrong product is a common cause: acrylic caulk in a wet area, a general-purpose sealant on a moving joint, or an acetoxy silicone on natural stone or some metals. Each fails in its own way.
Keep an eye out for any of the following:
- Wide, uneven beads that look worse than the old ones
- Leaks that keep coming back after resealing
- Decorators’ caulk around a bath or shower
- Over-sealed joints coming away
Managing a site like Ightham Primary School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Surface by surface
Mouldy bath & shower sealant
Mould often spreads under the bead as well as through it. Once it’s all removed, the joint is treated so the new sealant starts clean.
Worktops & kitchens
If a worktop moves when you lean on it, the sealant will keep splitting. It needs fixing down first, which we will point out.
