New build and refits around New Zealand

New Zealand lies roughly 38 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand. There are a number of hotels within about 2 miles of New Zealand. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight.

For contractors on a campus like University Campus Aylesbury Vale, 0.8 miles to the south of New Zealand, facade and perimeter sealing has to fit around students and term dates. When units on a site such as Cambridge Close Retail Park (less than half a mile south-east of New Zealand) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

New Zealand is about 1 mile west of Elmhurst, in Buckinghamshire. If you are looking for facade sealing in New Zealand, we can help, as we do across Buckinghamshire. We work across 308 places in Buckinghamshire, from busy centres to rural villages. Our Oxford page has more on work in that area.

Business premises anywhere in HP19 and HP20 are within our area. For a building on Dunsham Lane, Drayton Road and Cannock Road or nearby, we can quote for facade joints. If your building is just outside New Zealand, we cover Elmhurst (1 mile east), Aylesbury (1 mile south), Watermead (1 mile north-east), Quarrendon Estate (1 mile west) and California (1 mile south). Nearby towns on our patch include 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).

Landmarks near New Zealand

Locally, jobs take us to sites close to The New Zealand pub, Buckinghamshire UTC and The PACE Centre, among other places. The closest station to New Zealand is Aylesbury station, roughly 0.8 miles south of the centre. A little further out are Royal Buckinghamshire Hospital (less than half a mile south) and Dinton Castle (3.8 miles south-west).

Facade sealing in New Zealand

Sealant around windows, doors and cladding panels stops rain reaching the wall behind. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. Site teams most often ask us about new sealant peeling off old mastic and staining on stone next to old sealant, across perimeter joints where frames meet the structure, cladding panel joints and shopfront frames. A specialist sealant contractor works differently from a general builder: on jobs in New Zealand, preparation and product choice get the time they need.

Around smaller places like New Zealand, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Signs you need facade sealing in New Zealand

Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.

Clients normally get in touch after noticing something like this:

  • Perimeter joints where frames meet the structure
  • Water coming in around window frames
  • Facade joints cracked through the middle
  • Air leaks through failed facade joints

Further education sites such as Buckinghamshire College Group, 0.8 miles south of New Zealand, are extended and refurbished from time to time, with mastic often programmed into the summer break.

Our contractor checklist

On site: what to expect

We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area. If others near New Zealand need work, visits can be combined. A fixed quote is given before anything starts.

  1. We plan access and the order of elevations with the client.
  2. Weather and temperature are checked against the product’s limits.
  3. We remove the old bead and check the edges are sound.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. Once signed off, the work carries our 12-month guarantee.

What we need from you

Advice

Questions about New Zealand

Can you take on a job at a hospital such as Royal Buckinghamshire Hospital?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

Is a smaller place like New Zealand outside your area?

No. Places such as New Zealand are covered as much as the big towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Is your workmanship covered by a guarantee?

Yes. It runs for twelve months and covers how we prepared and sealed the joints, though not damage or work by other trades.

Do you use silicone for external joints?

Low-modulus, neutral-cure silicone suits many facade and perimeter joints. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others.

Can you work on upper floors?

That varies with the building and the access on offer. Share what access exists or is planned when you send details.

Do you need to see the site first?

Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit.

Can weather delay the job?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Honest limits

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Joints too narrow for the movement they take, which need redesign
  • Water getting in through cracked render or porous masonry
  • Arranging specialist high-level access, which is planned with the client

If in doubt, call 01277 525 020 or send photos by email and we will say what we think before you book.

What we seal

  • Cladding panel joints
  • Perimeter joints where frames meet the structure
  • Coping and flashing joints
  • Shopfront frames
  • Window and door perimeters
  • Stone and brick facade joints

Owners, agents and contractors

We work for building owners and managing agents on sealant work across single buildings or whole portfolios. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so the building keeps working while we do.

How the job changes by surface

Cladding panel joints

Joints between cladding panels open and close with temperature. The sealant has to match the movement and the panel finish.

Precast concrete panels

Precast panel joints have to absorb thermal and structural movement. A sealant of the right movement class goes in over backing rod.

When to bring in a specialist

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
