Renovations and extensions

Villas, additions and big renovations across South Auckland and North Waikato.

Renovations

Bring new life to a home you already own

We specialise in large renovations and extensions, including projects that need special care and technical knowledge, like villa renovations. Working inside an existing structure is often harder than building new, so choose a builder who has done it many times.

Not sure where to start? Tell us what you would like to achieve and we will talk it through with you. Many of our renovation clients come back for their next home or an investment property.

What we take on

Renovation work we do

Sizes range from an ensuite to a full house rebuild.

Large renovations

Whole house renovations that change how a home works for your family.

Villa renovations

Careful work on older homes, keeping the character and fixing what's behind the walls.

Extensions and additions

More room for a growing family, built to match the house you have.

Bathrooms and ensuites

Leaking ensuite? We check, quote and manage every trade on site.

Recladding and leaky homes

Weathertightness repairs with specialist engineers, for people let down by poor workmanship in the past.

Decks and outdoor living

From a family deck to a big deck and retaining wall on a cliff above the Manukau Harbour.

Budgeting

Three things that help your renovation budget

Must haves and nice to haves

Write two lists and talk them through with us. A good builder can help you get more of both for your money.

Somewhere else to live

For a big renovation, budget for other accommodation while the work is done.

A contingency

Every project needs a buffer for surprises, like hidden rot in a wall that nobody could see before.

Reviews

Renovation clients on working with us

"

Another important difference with Heineke Builders has been their after sales service, which has been nothing short of excellent.

Renovation FAQ

Before you start

Should I ask for a fixed price or charge up?

Charge up means you pay for the actual time and materials, but the final price is unknown. A fixed price gives you more certainty up front. In a renovation some items still can’t be priced until the walls are open, so we mark those clearly in the quote.

Most building work needs a building consent. Tell us what you are planning and we will tell you whether your renovation needs one or could be exempt.

That depends on the size of the job. For a big renovation, plan and budget for somewhere else to live while the work is done. On some projects owners do stay: during one cladding repair the owners lived in the house the whole time.

We price any change in scope or materials before we start on it, whether you ask for it or it turns out to be necessary. That way you know what it costs and there are no surprises.
