Build With Total Peace Of Mind Knowing You’re Covered By Our Ironclad 6-Point Guarantee And Building License

Building a custom home is one of the most significant investments (in time and money) you will make in your lifetime. So it’s critical you choose a builder you can trust. A builder who has a Home Construction Regulatory Authority (HCRA) Licence (ours is #43453) and Warranty backed by the Tarion Warranty Corporation.

While other builders ask you to take all the risk, we offer 6 ironclad guarantees so you can rest easy knowing you will get the exact home you are paying for – on time and on budget. And that you enjoy both the building experience and the end result. These guarantees include:

custom house plans

Design Guarantee

Please don’t compromise on anything. This is your home. And we’re here to help you get exactly what you want. We will take time to understand your vision. We will help you clarify and refine your ideas until you can literally see yourself living in every room of your beautiful new home. And we will optimize every aspect for comfort and energy efficiency. In short, we guarantee to design the exact home you’ve been dreaming about.

Fixed Price Contract Guarantee

Don’t be rushed into signing a superficial contract with a builder who then charges you thousands for extras you thought were included. Our exhaustive contract details everything so you know precisely what you will get and how much it will cost. No hidden fees. No surprises. Just an honest, fully transparent, fixed price you can count on.

Warranty Backed by Tarion

While it’s the law that new home builders in Ontario are to be licensed by the Home Construction Regulatory Authority (HCRA), unfortunately there are illegal builders that are not licensed.

Likewise, all new homes in Ontario are required to have a Tarion Warranty (be sure to check that your builder is licensed by the HCRA and providing this Tarion Warranty) which protects you during and after construction and also includes:

  • One year workmanship, and building code compliance protection
  • Two year water penetration and cladding and systems protection (electrical, plumbing, HVAC)
  • Seven year structural protection
  • $40,000 of financial loss protection

We enrol your home with Tarion prior to starting construction and then provide you with a Certificate of Completion and Possession prior to completion - ensuring you’re protected at every step.

Energy Efficiency Guarantee

While other builders ask you to trust that your home is energy efficient (based on the fact they have charged you extra for so-called energy efficient building materials whether they have installed them correctly or not), we have our homes independently tested and verified. This includes a Blower Door Test that measures the air changes per hour in your home (to ensure your home doesn’t ‘leak’) and an EnerGuide Rating that gives you a rating of your home’s energy consumption measured in gigajoules per year. You will receive all test results and certificates (including an Energy Star or Net Zero Labels and Certificates and an EnerGuide Rating) so you know for sure you have a genuine high-performance home.

Completion Date Guarantee

Sadly, delays in the building industry are so common, people come to expect (and accept) them. But you shouldn’t. After all, a promise is a promise. And a contract is a contract. Our proven scheduling process (with limited project volume) enables us to deliver on time – every time – guaranteed.

Communication Guarantee

When building a home, it’s natural for friends to ask how things are going. Many people find it embarrassing to admit they don’t know because their builder doesn’t keep them updated (and rarely returns phone calls and emails). When you build with Avvio, you have direct access to the owners so you can ask questions at any time. We will keep you fully informed with regular updates. And with full access to our Building Management Platform you can follow every step of your build. 

On top of that, you can be sure you will always be treated professionally and kindly. You will be listened to and respected. We will honour our commitments in full and always speak the truth. These aren’t merely guarantees, they are principles we live by.

If these are the qualities you are looking for in your builders -- the people who will help you bring your vision to life in a stunning, high-performance home -- we invite you to get in touch for a free consultation. We would be glad to answer your questions and share tips from our vast experience designing and building elegantly functional, supremely comfortable, measurably energy efficient homes. And when the time is right, we’d be honoured to work with you to bring your dream to life.
