The fact that our service to identify harmful substances in old homes is used every time by Avvio so that the substances can be removed correctly is proof that they are aware of environmental laws and care about the community and their workers. Some others try to get away with not doing this to save money in time putting those exposed to them during the demolition and removal process at risk. Also, their project schedules are realistic, and they are easy to work with so I can definitely recommend them.

I've had the opportunity to work with the Avvio crew on several projects over the last few years. The amazing team at Avvio consistently come up with modern built homes that go beyond the standard, focusing on not just the “visible” attributes but ensuring that they are at the leading edge using the latest technology in both high performance building envelopes and mechanical systems. Building better isn’t easy, but Paul & Vince have the experience and knowledge to build homes that are comfortable, secure and hit that sustainable marker for all their clients. I look forward to collaborating with Avvio on future projects. Always a pleasure!

We have been providing electrical services to Avvio for over 10 years now. We have a lot of experience working with Vincent, Paul and their team. They are very organized and professional. Their scheduling is always on time and work sites are clean and safe. Their design package includes a detailed electrical plan, making our job easier and eliminating the chance of mistakes. Decisions are made by them before we start our work so nothing is decided on the fly, which creates a smooth work environment.
