About our remedial sealant in New Zealand
A movement joint stops working when its sealant splits or sets hard. We cut out the failed sealant and set the depth with backing, before resealing with a flexible product suited to the movement. Common call-outs are for black mould underneath the bead and caulk or the wrong sealant used in a wet area, across expansion joints, botched or over-sealed joints and failed movement joints.
Around New Zealand, it’s 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.
Every job is covered by a 12-month guarantee.

Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Have loose fittings fixed before resealing
- Keep movement joints clear of mortar and paint
- Clean sealant with mild products only
- Keep the room well ventilated
Keep the room ventilated: use the extractor or open a window after showering.
Mould under a second layer of sealant keeps growing out of sight. By the time it shows through, the joint is well past saving.
How we quote for remedial sealant
Some jobs are bigger than they look, and some smaller. The main factors:
- How easy the joints are to reach
- How many areas need sealing
- The type of sealant required
- The number and length of the joints
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Helping us quote
To make quoting easier, let us know:
- Photos by email, if that’s easy
- The address or postcode of the job
- How we’d reach the joints
- How many joints, rooms or windows are involved
Getting a quote is simple: let us know what needs doing and where and its rough size. Photos by email help us understand the job.
Surface by surface
Over-sealed & botched joints
Previous removal attempts can leave scratches or gouges. We take care not to make it worse, and tell you about any damage we find.
Worktops & kitchens
If a worktop moves when you lean on it, the sealant will keep splitting. It needs fixing down first, and we’ll tell you if we find it.
Leave it or put it right?
Remedial work takes longer than a straight reseal, but not by much: it takes a few hours, depending on how many layers have to come out. Compared with chasing the same leak every few months, it’s time well spent. Where a wall is exposed, as many are in small places like New Zealand, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

Questions from New Zealand
Do you work for landlords with property near Aylesbury station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.
Do you take on hotel work around New Zealand?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.
Can failed expansion joints be resealed?
Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.
Can you fix a reseal that hasn’t worked?
Yes. We’ll take all the sealant out, look for why it failed and reseal it properly.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Are you fully insured?
Yes. We are fully insured.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
What if resealing will not fix my leak?
In that case, we tell you what we have found. You may need a plumber or bathroom fitter.
What we can’t put right
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- A tray or worktop that needs refixing first
- Plumbing leaks behind walls or under trays
- Tiles that have come away from the wall
If in doubt, call 0345 464 0079 or email us and we’ll say what we think before booking.

Remedial sealant around New Zealand
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. New Zealand has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.
For site and facilities teams at buildings such as Elmhurst 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. Rented homes near Aylesbury station change hands often, and botched sealant from a previous quick fix is easier to strip out between tenants. For an older house near a landmark such as St Peter's, walls and floors in older homes can move, and sealant and grout show it first.
New Zealand is about 1 mile west of Elmhurst, in Buckinghamshire. Every kind of property in New Zealand is covered for remedial sealant, old or new, large or small. Every job comes with our one-year guarantee. New Zealand is one of 263 places in Buckinghamshire where we work. For nearby work, see our Oxford page, about 19 miles away.

What happens on the day
You don’t need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes a few hours, depending on how many layers have to come out for a typical job. Somewhere like New Zealand needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
