FulFill Your Dreams

Our Philosophy

A great renovation is equal parts craft and process. We start by clarifying scope, constraints, and priorities, then we plan the work so it stays safe, code-compliant, and predictable. On site, we protect your home, communicate clearly, and keep standards high from structure through finish. If you are working with a designer or architect, we focus on buildability, details, and keeping the design intent intact.

AWARDS & TESTIMONIALS

HomeStars Best Of The Best

Client satisfaction drives everything we do, with positive reviews reflecting our commitment to quality.

Who We Are

JB Contracting is a family business founded by Jim Bojeczko in 1989. Today we deliver renovations, additions, and custom builds across Toronto with a calm, technically capable approach that clients and design partners can trust.

 We run a tidy site, communicate clearly, and close out properly, so you feel informed and confident from first conversation to final walkthrough.

"Jim is awesome!"

"Jim is awesome! He immediately responded to my request, came on-site and talked through every detail clearly up-front, and kept me informed throughout the entire process. Jim was always on-time, provided quality work, and stayed on-budget (other than a small change to the stairs which he discussed with me well in advance, and left the decision for me to make). He's honest and his rates are reasonable given the quality of the work provided. He framed by basement after an underpin. He also installed new basement stairs, and they look fantastic.Overall a very positive experience! I would use JB Contracting again, and I would refer them to others. 10/10"

"Attention to Detail

""We are very happy with the work JB Contracting did in renovating the main bathroom in our home. The process started with a consultation so that Jim understood our wishes. He provided a detailed estimate for the work involved, then he directed us to his trade-only suppliers from whom we could select the bathroom fixtures and tiles of our choice. The worksite was left clean at the end of every day. The materials used were top notch, such as the Schluter line of products. We are very pleased with the final product. The attention to detail and regular communication about every step of the process was exceptional. 10/10"
