About Us

Our Philosophy 

Opal Building Co. is a construction company serving London, ON, with a focus on residential remodels and renovations. 
Our process begins with gaining a detailed understanding of the client’s unique wants, needs and design preferences. Our team stays up to date on the latest in building science, materials, codes and trends to inform our clients of important factors to consider when choosing a design. Some clients know exactly what they want, while others need help conceptualizing a new vision for their space from the ground up. Whatever the case may be, we offer a full suite of design services that can be tailored to suit your specific needs and budget.
Co-owners, Kevin Bartman and Tyler McIlroy, believe that a hands-on approach produces the best results. When construction begins, they are both regularly on site carrying out the work with their own hands to ensure that every detail conceived in the design stage is crafted to perfection. Ingenuity, modernization and efficiency define their approach to business management, allowing them to spend less time doing paperwork and more time face-to-face with their clients. With over 20 years of combined experience in a diversity of construction fields, the duo is poised to lead the most demanding projects.

After working for his family plumbing business throughout his youth, Kevin started a property management and renovation company. He expanded his expertise beyond his plumbing base to encompass all areas of construction and developed an aptitude for design. He quickly attained a client base that allows him to manage over 100 assets and gained a wealth of experience in the real estate industry. Over the years, he transformed dozens of outdated rental properties into high-end commodities that command top dollar in the marketplace.

Tyler started in his father’s roofing business, then expanded his skillset by working in a variety of trades including masonry, concrete and carpentry. As a promising young talent, he was hired as the apprentice of a highly sought-after custom home builder who became his mentor. Later, he worked as a lead carpenter for multiple contractors and developers, being promoted at each step along the way. Ultimately, he opened his own residential construction company with a focus on high-end carpentry.
