Expansion joint sealing for New Zealand sites
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Building owners, agents and FMs in New Zealand
Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. New Zealand can form part of a wider programme.
Expansion joint sealing in New Zealand, done properly
Every structure moves a little, all the time: temperature, moisture, shrinkage and loading all make materials grow and shrink. Expansion and movement joints are built in so the structure can move without cracking. We seal and reseal movement joints in walls, panels, decks and floors. If you have joints where the bead has lost adhesion and layers of sealant in a movement joint, we can help, whatever the surface. Facilities teams, main contractors and managing agents in New Zealand tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Around smaller places such as New Zealand, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

How the quote is worked out
A fixed quote reflects the actual work. It takes account of:
- Whether old sealant has to be cut out first
- Which sealant the job calls for
- Any access equipment needed
- Phasing around occupants
The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
Details that help us quote
To price the job accurately, we need to understand the site. Useful things to include:
- A wide shot and a close-up of the area
- The asbestos register, for older buildings
- The site address and postcode
- Approximate linear metres or a joint schedule
Let us know the site, the scope and your timescale, and we will put a fixed quote together. The easiest way is to speak to us on 01277 525 020 or email the details over.
Diagnose, treat, sign off
Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. For work around New Zealand, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.
- We assess the joints on site or from photographs, noting widths and how each has failed.
- You receive a fixed quote stating the product and the movement it is rated for.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
What we need from you
- Arrange parking or a loading space
- Send your site hours and access windows
- Make sure the joints can be reached
Getting a fixed quote
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.
Advice
Why act early in New Zealand
Doing joint resealing alongside other planned works can save on access. Leaking joints need sealing now, as damage continues meanwhile. We can split the scope into urgent and planned. Halls, stores and units around places like New Zealand may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a quote once you have the details.

Traffic, movement and joints around New Zealand
New Zealand lies roughly 38 miles out from central London. Warehousing clusters around the motorways that ring and radiate from London. New Zealand sits in one of the drier corners of the country, the South East. Even so, yard and car park joints are only sealed when they’re dry and clean, and where de-icing salt is spread in winter, open joints let it in.
Hospital campuses such as Royal Buckinghamshire Hospital, under half a mile to the south of New Zealand, grow in stages, leaving movement joints wherever new blocks meet old. Campuses like University Campus Aylesbury Vale, 0.8 miles south of New Zealand, mix old and new buildings, with movement joints wherever they meet. Places like Cambridge Close Retail Park (to the south-east of New Zealand) put trolleys over floor joints inside and cars over slab joints outside.
New Zealand is about 1 mile west of Elmhurst, in Buckinghamshire. Our applicators travel to New Zealand for work on movement joints, handled exactly as we handle every other area. Our Buckinghamshire coverage takes in 308 places, from busy centres to rural villages. Oxford is covered too, around 19 miles from New Zealand.
Commercial sites across HP19 and HP20 are covered. We cover commercial and managed buildings on Dunsham Lane, Drayton Road and Cannock Road. Close to New Zealand, our area also takes in Elmhurst (1 mile east), Aylesbury (1 mile south), Watermead (1 mile north-east), Quarrendon Estate (1 mile west) and California (1 mile south). Further afield, our area takes in High Wycombe (14 miles south), Chesham (12 miles south-east), Buckingham (14 miles north-west), Amersham (14 miles south-east), Princes Risborough (7 miles south) and Haddenham (6 miles south-west).
What’s near New Zealand
We work on buildings around The New Zealand pub, Buckinghamshire UTC and The PACE Centre and the streets around them. The nearest railway station is Aylesbury station, about 0.8 miles south of the centre. A little further out are Royal Buckinghamshire Hospital (under half a mile south) and Dinton Castle (3.8 miles south-west).
New Zealand: questions and answers
Can you take on a job at a hospital such as Royal Buckinghamshire Hospital?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is New Zealand too far out for you?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
How soon can the area be used again?
We’ll confirm how long the chosen product needs to cure.
Can you fit around our working hours?
Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
How long will the new sealant last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
What guarantee do you give on joint sealing?
The workmanship is guaranteed for 12 months from sign-off and we hold public liability insurance. Keeping joints clear of debris helps them last.
Doing it in-house
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

After the work
After handover, a little attention goes a long way:
- Leave barriers in place until fresh joint sealant has cured
- Raise snow-clearing blades over deck joints where possible
- Treat a small split as a warning, not a cosmetic issue
- Record the sealant used and the date in the O&M file
Floor joints on main traffic routes need watching more closely than the rest. Keep racking feet and heavy point loads off joint lines, and report any chipped edges early.
On a multi-storey car park, a failed joint normally shows up as a leak onto the deck underneath. That water often carries de-icing salts with it and it can affect the structure over time. Sealing the joint promptly stops it at source.
