About our remedial sealant in Olney
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. We work on failed movement joints, mouldy bath & shower sealant and botched or over-sealed joints, and common reasons people get in touch are leaks that keep coming back after resealing and smears and lumps from a botched reseal.
Around Olney, you’ll mostly find houses and bungalows, some older and some much newer. Bathrooms and kitchens here get the same daily wear as anywhere, and the sealant and grout show it first.
A 12-month guarantee comes as standard.

Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
When something else is needed
New sealant can’t fix everything, and we’ll tell you before we start. Sealant will not put right:
- Water damage behind tiles that needs a tiler
- A cracked shower tray or bath (that needs repair or replacing)
- Movement from fittings that are not supported
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before booking.

What happens on the day
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take a few hours for a typical bath or shower, longer where several layers have been applied. For a job in Olney, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by checking the joint for movement, leaks and the reason it failed.
- Every layer of old sealant is cut and cleaned out.
- 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.
- Finally we finish the joint and talk you through what we found.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention any leaks or damp you’ve noticed
- Tell us about any previous sealing or DIY attempts

Advice
Leave it or put it right?
Mould under a bead cannot be reached by cleaning. Removal is the only way to get at it, and the joint treated and dried before resealing. In an older home around Olney, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference.

When to call us in Olney
One of the commonest remedial jobs is sealant on top of sealant. New silicone can’t stick to the old bead, so the top layer lifts and water and mould collect between the two.
Look out for any of the following:
- Caulk or the wrong sealant used in a wet area
- Black mould underneath the bead
- Beads that never stuck properly
- A shower that leaks however often it’s resealed
For site and facilities teams at buildings such as Olney Middle 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.
Before you book anyone
- How long to leave it before use
- Whether they’re fully insured

Leaking trays & enclosures
When failed joints are the cause, they’re all cut out and renewed, tray edges and screen profiles included.
What remedial sealant looks like in Olney
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Homes close to Church of Saints Peter and Paul include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant.

Common questions in Olney
Do you cover Olney for remedial sealant?
Yes. We work across London and the South East, and Olney is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing.
Is Olney within the area you cover?
Yes, Olney is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work for letting agents?
Yes. Domestic, commercial and hotel work are all part of what we do.
Someone sealed over the old bead. Can you fix it?
Yes. It’s slower than a standard reseal, because every layer has to come out cleanly, but it’s the only way the new joint will last.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll tell you what we are using.
I’m a tenant. Can you help?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Do the sealants smell?
Some sealants have a smell while they cure, but it fades. Opening a window helps.

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Deal with small splits early
- Always have old sealant cut out, not covered
- Keep bleach and abrasives off the bead
- Run the fan after every shower
Clean gently: no scraping, scouring pads or harsh chemicals.
If a joint has failed more than once, stop resealing it. Get the cause found first, or the next bead will go the same way.
