Planning to renovate, extend or upgrade your Auckland home?
Hercules Construction provides home renovations, extensions, recladding and remedial building services across Auckland.
We work with homeowners looking to improve existing homes — whether that means modernising the interior, creating more living space, extending the house, replacing ageing cladding or carrying out remedial building work.
Renovating an existing property is different from building new. Existing construction, previous alterations and hidden conditions all need to be considered when planning and carrying out the work.
Our team takes a practical approach, with clear scopes, communication throughout the project and coordination of the different trades required to complete the work.

​
Renovating an Existing Auckland Home
Existing homes often come with challenges that aren't visible until work begins.
Once existing wall linings, flooring, cladding or fixtures are removed, previous alterations or deterioration may become apparent.
Depending on the age and condition of the property, this could include damaged timber, uneven framing, outdated services, previous repairs or construction that differs from available plans.
Our approach is to assess what can reasonably be identified before work starts and communicate with you if additional conditions are uncovered during construction.

Home Extensions Auckland
Need more room but want to stay in your existing home?
A home extension can create the additional space your family needs while allowing you to remain in the location and property you already know.
Hercules Construction undertakes house extensions and residential alterations throughout Auckland, working with homeowners and their designers to turn approved plans into completed building work.
Home extensions can create:
-
Additional bedrooms
-
Larger living areas
-
Additional bathrooms
-
Larger kitchens and dining areas
-
Open-plan living spaces
-
Home offices
-
Family rooms
-
Improved indoor-outdoor connections
Extension projects can involve foundations, structural alterations, framing, roofing, cladding, windows and doors, insulation, interior linings and finishing work.
Where architectural design, structural engineering or building consent is required, we can work alongside your architect, designer, engineer and other consultants during construction.
Extending an Existing House
One of the most important parts of an extension is connecting the new construction to the existing home.
Roof lines, floor levels, framing, cladding, windows, waterproofing and interior finishes all need to work together.
Our focus is not simply on constructing the new area, but on making sure the extension integrates practically with the existing building.

Recladding Auckland
The exterior cladding of your home plays an important role in protecting the building from Auckland's weather.
Ageing materials, previous installation issues, deterioration or water ingress can sometimes mean that repairs or replacement are required.
Hercules Construction provides recladding, cladding replacement and remedial building services in Auckland for existing residential properties.
Depending on the condition of the property, work may include:
-
Full or partial recladding
-
Cladding replacement
-
Weatherboard replacement
-
Localised cladding repairs
-
Window and door replacement
-
Flashing replacement and repairs
-
Timber repairs
-
Remedial carpentry
-
Leak-related repairs
-
Exterior finishing work
The correct approach depends on the existing cladding system, condition of the building and extent of any underlying damage.
Recladding & Hidden Building Damage
With some recladding and remedial projects, the full condition of the structure cannot be confirmed until the existing cladding or affected materials are removed.
If damaged or deteriorated framing is discovered, the affected areas need to be assessed before the new cladding is installed.
We aim to clearly identify what has been allowed for in our scope and communicate with the homeowner if additional remedial work becomes necessary.
Remedial Building & Leak Repairs Auckland
Not every property requires a complete renovation or reclad.
Sometimes the issue is confined to a particular area of the building.
Hercules Construction also undertakes residential remedial building work and leak-related repairs across Auckland.
This may include:
-
Cladding repairs
-
Weatherboard replacement
-
Window and door repairs or replacement
-
Flashing repairs
-
Leak investigation and associated building work
-
Damaged timber replacement
-
Interior reinstatement following repairs
-
Exterior building repairs
-
General remedial carpentry
The appropriate repair depends on where the water is entering, the construction of the building and the condition of the surrounding materials.
Where possible, we focus on identifying and addressing the underlying building issue rather than simply covering the visible damage.
