Transform your Mississauga home with custom second stories, extensions, and professional permit management.




Proud to serve communities throughout Mississauga, ON
We handle all municipal applications and structural engineering for the City of Mississauga, ensuring your addition meets all local zoning and safety bylaws. Our team navigates the Committee of Adjustment for variances, so you don't have to deal with city hall bureaucracy. This proactive management prevents costly legal delays and ensures a smooth approval process for your home expansion.
Our designers ensure that your new addition looks like it was always part of the original home, matching brickwork, rooflines, and trim with meticulous detail. We use 3D rendering to visualize the project before construction, allowing you to see how the new structure impacts your curb appeal throughout your Mississauga neighborhood. This attention to detail protects your property value and creates a cohesive, beautiful living space.
Living in Mississauga means dealing with extreme humidity and freezing winters, so we build every addition with advanced insulation and moisture barriers. We use high-performance building materials that exceed standard Ontario building codes to reduce your energy costs and prevent structural issues. Our projects are built to withstand heavy snow loads and torrential rains, providing you with long-term peace of mind in a changing climate.
We conduct a thorough walkthrough of your Mississauga property to evaluate the structure, soil conditions, and your expansion goals. This allows us to provide an accurate preliminary budget and identify potential zoning challenges like lot coverage limits early on. This step is vital to ensure your vision is feasible within the local regulatory framework.
Our in-house design team creates detailed metric-scale drawings that meet all City of Mississauga requirements for building permits. We manage the submission to city hall and coordinate with structural engineers and HVAC specialists to ensure every technical detail is approved. This stage removes the stress of dealing with municipal bureaucracy and sets a solid foundation for legal compliance.
Before the main addition begins, we prepare the site and reinforce any existing structures, such as the foundation or main-floor walls for a second-story top-up. We take extensive measures to protect your existing home from dust and debris, installing floor protection and temporary walls. This phase is critical for safety and ensures the new addition is anchored to a strong, stable base.
Our skilled tradespeople build the frame, install high-efficiency windows, and complete the roofing to make the structure water-tight as quickly as possible. Once enclosed, we handle all plumbing, electrical, and interior finishes, ensuring the new space flows seamlessly into your original home. We conduct a final walkthrough to ensure every detail meets our standards and your total satisfaction.

Learn MoreWe needed more space for our kids and decided on a rear two-story addition to our home in Streetsville. Ricardo and the Built By Pros team were incredible throughout the six-month project, especially with the complex foundation work next to the Credit River. They managed the permits perfectly, and the new 800-square-foot extension looks like it was built with the original house. We couldn't be happier with the outcome and the craftsmanship.
I hired Built By Pros Inc. to add a custom home office above my garage in Erin Mills because I was tired of working from my kitchen table. The project stayed on schedule despite a few winter storms, and Suzanne's design for the skylights and built-in shelving truly maximized every square inch. They were very clean during construction, which was important since I was still living there during the build. Highly recommend them for any addition.
After looking at the crazy housing prices in Meadowvale, we decided to stay put in Erindale and add a second story to our bungalow. The team at Built By Pros was so supportive, guiding us through the zoning hurdles and structural upgrades needed for an older home. The project was completed in four months, and the addition including a master suite with a luxurious walk-in shower is now our favorite part of the house. The attention to detail on the custom exterior brick match was amazing!
