Frequently Asked Questions

By contacting the Sertorio Home’s office by email or phone, a consultant will contact you to arrange a FREE, no obligation visit to your home.
Leave that to us. We will organise approvals with the council and Water Corporation. We will also organise the survey and engineering details.

As you can appreciate, every council has differing needs and procedures for building. Some council’s are also inundated with approvals, although we work closely with councils, there may be an occasional delay with approvals. If you feel that the approval process is unusually long, we recommend that you contact the council direct.

It is advisable to contact your home insurance company to advise them of the renovation. They can advise you on your individual policy requirements.

Each renovation is unique. A time frame will be devised based on your current home and proposed renovation. You will be advised prior to signing the contract the allowable working days to complete works.

This is a personal choice. You should speak with your consultant and site manager before making your decision.

Where possible, sub-contractors to Sertorio Homes will keep mess to a minimum. To ensure you end up with the best possible renovation, it may be necessary to carry out demolition. You will need to cover furnishings and it may become unpleasant for a short period of time. Each renovation is unique and it would be best to speak with your Site Manager to determine your individual needs.

No. Sertorio Homes have qualified designers who will draw up your design plans in-house. Sertorio Homes do not use other architect designs, as we will draw to specification.

Yes you can. Any changes prior to the contract being signed are made in-house at no extra charge. Any changes after contract signed may result in additional costs onto the contract.

No. Any additional tradespeople not directly working with Sertorio Homes will not be covered by insurance. Any damage that they may cause on the renovation will also not be covered by insurance. Speak with your Site Manager to devise the best course of action prior to employing additional tradespeople.

Yes you can. If you decide to provide your own products, please advise your Consultant prior to materials being purchased. If in doubt, speak with your Consultant. Any changes can affect both the price and scheduling of your job.

Practical completion means the renovation is complete, but does not mean it is perfect. In other words, you can live in the house. At time of handover, a Practical Completion inspection will be made by the Sertorio Homes director, and any defects will be noted. These will be rectified within a reasonable time.

Sertorio Homes only carries out renovations in the immediate Perth metropolitan area. Contact our office to confirm if we renovate in your area.

The simplest way to know if a demolish and rebuild is the right solution for you, is if you like where you live but not the home you are currently in. And if you cannot obtain the desired outcome through renovating or extending.

The entire home is demolished, and we start from scratch. Renovating means you are altering the existing home.

No, the entire home will be demolished therefore you will need to find other living arrangements. For some people this means renting or living with family while the demolish and build takes place.

Leave that to us. We will organise approvals with the council and Water Corporation, as well as the survey and engineering details. You can rest assured the demolish and rebuild of your Perth home will be carefully managed by us from start to finish.

Every demolish and rebuild project in Perth is unique. A time frame will be devised based on requirements for site preparation and your home design, usually the whole process takes approximately 1 year. Since Covid-19, our industry has faced challenges, which we continue to navigate through with a realistic outlook.

The cost of your demolition and rebuild is determined by a few factors, including the size and scope of your renovation. Build costs will also depend on things like the materials and finishes used.
