Uneven floors, cracks creeping across a wall and doors that no longer latch usually point to something moving under the house, which is why the best foundation repairs in Blenheim start with a proper look beneath the floor rather than a patch on the surface. The specialists below repile, jack and relevel homes across Marlborough, replacing rotted or shifted piles and bringing buildings back to level. House Relevelling and Piling Services and Coffey House Removals both work as Licensed Building Practitioners on this kind of foundation work.

How to Choose the Right Foundation Repair Specialist in Blenheim
- Check the contractor is a Licensed Building Practitioner with a foundations licence, since a full repile is restricted building work and needs a signed memorandum for consent.
- Ask whether they work to NZS3604 and who prepares the engineering input, because a geotechnical report often sets the depth of the new piles.
- Look for a firm that inspects the subfloor before quoting rather than pricing off a photo, as the cause of the movement changes the repair entirely.
- Confirm whether the job needs a full repile or a smaller jack and pack, and get the difference explained in writing before you commit.
- Make sure the quote covers the extras that catch people out, such as clearing old piles, concrete paths, chimneys and reinstating services.
Frequently Asked Questions About Blenheim Foundation Repairs
How do I know if my house needs repiling or relevelling?
The usual signs are sloping or bouncy floors, gaps opening between the wall and the skirting or ceiling, cracks in linings, and doors and windows that stick or will not close. Visible rot, splitting or leaning piles under the house is a clearer sign again. A subfloor inspection is the only way to tell whether the piles themselves have failed or the ground beneath them has moved.
Do I need a building consent to repile my house in Blenheim?
Yes. A full house repile is restricted building work and requires consent from the Marlborough District Council, with the work carried out to the relevant building regulations. Smaller repairs may fall outside consent depending on scope, so confirm with your contractor before any work starts.
What is the difference between repiling and jack and pack?
Repiling replaces the piles themselves, which is the answer when timber piles have rotted or a large part of the subfloor has failed. Jack and pack lifts the house and packs the existing piles to bring the floor back to level, and suits smaller, localised drops. Building Performance publishes guidance on jacking up a foundation that explains how the lift should be done.
Should I get an engineer involved before I get a quote?
It helps. A geotechnical engineer can assess the ground and a Scala penetrometer report will recommend how deep the new piles need to go. With that in hand a contractor can price the work far more accurately, and both firms on this page will tell you when a report is worth getting.
How long does a repile take and do I have to move out?
An average full repile runs about five days, though it depends entirely on the size of the house and what is found underneath. You will usually need to vacate while the house is off its piles, and services may need disconnecting, but furniture normally stays put unless internal access is required.
Can I renovate first and repile later?
It is better the other way around. The house is disconnected from its piles and lifted on hydraulic jacks during a repile, so new linings, tiling and joinery are at risk if the levelling happens afterwards. Brickwork and concrete chimneys cannot be lifted and have to be removed, which is another reason to sort the foundation first.
How do I check a contractor is properly licensed?
Foundation work is restricted building work, so the person carrying it out or supervising it must hold the relevant licence class. You can look up any practitioner on the public Licensed Building Practitioners register by name to confirm their licence is current.
What affects the cost of foundation repairs?
Access under the house, the depth the new piles must go, the number of piles, and what has to be removed first all move the price. Concrete paths, a concrete chimney, a concrete floor section or an old set of piles that has to be dug out add both time and cost, which is why quotes follow a site visit rather than a phone call.
