Innovative, Industry-Leading General Contractor in London, ON
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.
