Dion Goncalves
Dion Goncalves
Owner (Rock Bottom Underpinning)

Very few people have seen this city transform like Dion has. Born and raised in Toronto near Parkdale and Little Portugal, he witnessed the downtown core and its surrounding neighbourhoods blossom into vibrant urban communities with the arrival of thriving independent businesses and sophisticated young professionals.

Dion started in the construction industry by creating a successful underpinning and foundation services company in Toronto. His first underpin was done on his very own home. Seeing the need and demand for creating additional space to not only provide for extra living space for family, a nanny suite, or for the in-laws, he jumped on an opportunity to make a difference within the city. He gained his knowledge of construction by working from the ground up and understanding the fundamentals of home building.

Dion is also multi-lingual! He is able to read, write and speak English, Portuguese, and Spanish fluently with good command of Italian, French, & Arabic.

Dion and his crew completed our underpinning safely and on schedule. The price was competitive, Dion was responsive, and any small issues that came up along the way were dealt with professionally. We were very pleased and wouldn't hesitate to recommend Rock Bottom.

- Alex

After getting 3 quotes we decided to hire Dion and his Rock Bottom Underpinning team. Our basement height was under 6 ft and now is 8ft. Dion & his crew do excellent work, and kept us well informed through the entire process. His estimate of cost and time was right on the target.

- Derek

This was not our first renovation but it is our biggest one and we had been planning and saving for an overhaul of our century home for 3 years. We sourced out three quotes and Dion at Rock Bottom was not only the most affordable but we also had a gut feeling we could trust him from Day 1.

- Katie

Rockbottom’s workmanship, customer service, team and overall final product was excellent! The project consisted of a full underpin, new water service and sewer main, and a large/complicated back addition. Dion and Jamie were always easily accessible and ensured the project ran efficiently and to budget

- Naram
