FAQs
Kitchen Renovation FAQs
Got questions about kitchen renovations in Sydney? We’ve answered the most common ones—from costs and timelines to design tips and council approvals.
How much does a kitchen renovation cost in Sydney?
Kitchen renovation costs in Sydney typically range from $25,000 to $60,000+, depending on size, materials, and scope. Kastell offers line-item quotes so you know exactly where your money is going. For cost planning, explore the realestate.com.au renovation calculator.
What’s included in a kitchen renovation cost breakdown?
A detailed cost breakdown includes demolition, cabinetry, benchtops, appliances, plumbing, and electrical. Kastell provides transparent, itemised quotes—no grey areas. Learn more on our Our Processes page.
Should I repaint or replace my kitchen cupboard doors?
Repainting is cheaper but may not last. Replacing doors offers a fresh look and better durability—ideal for dated or damaged cabinetry. Kastell can help assess your best option based on budget and condition.
Is it worth replacing old kitchen cabinets, or should I keep them?
If your cabinets are structurally sound, refacing may save money. But for layout changes or upgrades, replacing is often more cost-effective long-term. Learn about cabinetry options on our Our Processes page.
What is the best kitchen layout for functionality and space?
U-shaped, galley, or L-shaped layouts suit most homes. The best layout depends on your space and how you cook—Kastell will guide you through this in design. For layout inspiration, visit our Pinterest boards.
How long does a kitchen renovation take from start to finish?
Most renovations take 4–6 weeks depending on complexity, materials, and trades. Kastell provides a live schedule and regular updates. Learn more in our Our Processes.
Can I live in my home during a kitchen renovation?
Yes, with planning. Kastell uses dust control, clear access, and daily site cleans to minimise disruption while keeping your home liveable. See our process page for details.
How can I make my kitchen renovation more sustainable?
Use FSC-certified timber, low-VOC paints, LED lighting, and energy-rated appliances. Kastell supports eco-conscious material selection. Compare appliances at the Energy Rating site.
Can you renovate a kitchen in an apartment or strata property?
Yes, but it may require strata approval and limited access logistics. Kastell has experience delivering smooth renovations in apartments. Check with your strata manager first.
