What Our Satisfied Clients Say About Sertorio Homes

Gautam Kastha ★★★★★ a month ago
We had a very good experience working with Sertorio on our home renovation project! Their commitment to smooth timelines, quality and attention to detail was impressive!
From start to finish, our ideas were valued, and we appreciated the regular updates. Post-completion service has been prompt and reliable! … Read More
To take it to the next level we suggest: refining site supervisor-contractor communication would streamline processes even further.
Deepti Raval ★★★★★ 7 months ago
Our experience with Sertorio Homes for our second-story extension was outstanding. From the initial planning and approval stages to the final construction, Bruce and his team exemplified honesty, integrity, collaboration, and professionalism. Bruce took the time to listen and understand our needs and … Read More specific requirements to suit our family dynamic with multi-generational living. Their initial estimate and the final contract value was spot on and took out the angst of changes/variations as every little detail was thought and included in the contract with no surprises later. Nikita’s vision, design skills and attention to not only big items but also the minor details resulted in a functional, modern and contemporary design.
Jake, our supervisor is a superstar! He communicated the plans clearly, kept us informed of any schedule changes, and worked with us actively to resequencing the works to mitigate any delays and always addressed our concerns. As part of the construction activities were in the winter months and this resulted in water ingress during storms, Jake came out and personally arranged for specialist trades to be on site within the hour and made sure that the issue was fixed, and property was made watertight. He was happy to receive calls during day or even late at night. They made sure all damage caused by storms to our existing property was repaired and restored to an even better condition than before.
The tradespeople were respectful, approachable and fantastic to work with. They delivered excellent workmanship, responded promptly to any issues, and always found solutions. They were also mindful that we were living in the house during the construction and tried to be as unobtrusive as possible.
Another example of their client focused approach was that they kept the scaffolding (external access to upstairs), skip bins, portable toilets for much longer than any other builder would have so that we didn’t experience any inconvenience as a result of them working on our property.
Despite initial nerves about the project, we couldn't be happier with the outcome. Our new home is everything we hoped for and more, thanks to Bruce and his team at Sertorio Homes.

Sertorio Homes Perth FAQs: Everything You Need to Know

I want to renovate my home. What do I need to do?

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.

What approvals do I need?

Leave that to us. We will organise approvals with the council and Water Corporation. We will also organise the survey and engineering details.

Why is the council process taking so long?

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.

Do I need to change my own insurance?

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

How long will my renovation take?

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.

Should I move out of my home during the renovation?

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

Will my home become messy during the renovation?

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.

Do we organise our own design plans?

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.

Can I change the plan concept after it has been drawn?

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.

Can I employ additional tradespeople while Sertorio Homes is on site?

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.

Can I purchase my own fixtures/fittings?

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.

What is practical completion?

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.

What areas do you work in?

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

How do I know if my house is a good candidate for a demolish and rebuild?

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.

How does the process for demolish and rebuild differ from renovating?

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

Can I still live in my home during a demolish and rebuild?

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.

How do I ensure that my new home will comply with building codes and regulations?

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.

How long does a demolish and rebuild typically take?

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.

What is the average cost of a demolish and rebuild?

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. Want advice about the cost of a demolish and rebuild? Get in touch with one of our helpful Building Consultants for a guide.
