Wow! Working with Gateway group was a dream. We had thought about this remodel for 20 years. When their team was available, I asked if they would work on our project and I was so happy when they said yes. Because of the size of the project … More we were out of our kitchen for three months. They were professional, they were dedicated, they were kind, they listened and also shared their own ideas, they worked with our designer brilliantly, and went above and beyond at every turn. I simply can’t recommend them highly enough. They are dream team. When people come into our house, they are in love with our kitchen. We are too! I laid or hired them to work on the rest of the house and now my whole house is fantastic. I’m so happy I chose Gateway group.

I was working on completing a conditionally approved severance for my property in Hamilton. I reached out to Charles and the Gateway Group to seek some expertise and guidance to help me get the project across the finish line. This decision … More was one of the best decisions I have ever made on any project I have done.
Charles and Dan provided me with answers to every question I could think of, clear instructions for processes I didn’t understand, as well as a plethora of well vetted professional contacts (engineers, lawyers, landscape architects) for ever step of the project. They also acted as liaisons on my behalf and spearheaded communications with the CoH. This saved my countless hours of searching and emailing, as well as saving me money by helping me to secure well priced and efficient contacts. All of this would have made working with Gateway Group well worth the price by itself!
Sadly, after all the conditions had been met for the severance the City of Hamilton completely dropped the ball on finalizing the project. Here, Charles and his team went above and beyond the call of duty. They were relentless in holding the CoH’s feet to the fire with constant emails and phone calls and even eventually formally escalating the matter to the head of city departments after deadlines and promises had been missed and broken repeatedly.
Overall, I am beyond grateful that I partnered with Gateway Group on this project. I could not recommend them more highly. I believe the value they provided was at least 5x of the fee that they charged was. If you are doing any real estate project in Hamilton that you are considering seeking professional guidance on, I can confidently say choosing Gateway Group is the absolute best decision you can make!

Working with Gateway Group is an absolute treat. Their team is exceptionally professional, consistently prompt, and always true to their word. The quality of their work is outstanding - they pay close attention to detail, communicate clearly … More throughout the process, and deliver results that exceed expectations. It’s rare to find a company that combines reliability, craftsmanship, and genuine care for their clients the way Gateway Group does. I highly recommend them to anyone looking for dependable, high-quality service.

Simply put, Gateway Group can compete builds and renovations, other experienced renovating companies cannot.
Our bathroom renovation experience with Cory and Matt specifically was outstanding.
They arrived on schedule, communicated clearly … More about the work they planned to do and consistently reviewed progress with us at the end of each day/week. If they saw a potential issue, they brought it to your attention, shared what their concerns were and brought alternative solutions. They took pride in their work and we had no damage to other areas of our home.
We actually started our renovation with another company, and unfortunately, despite the reputation and experience of the previous company, they did not have the skills and knowledge that Gateway Group provided. Cory identified several issues done by the previous contractors that potentially saved us thousands of dollars of damage had they not been addressed. Cory and Matt thoughtfully considered how to correct the multiple code violations and achieve the build as per the design plan.
Renovating 100+ year old homes, especially when starting on a 40% completed renovation comes with multiple challenges. Gateway understood the assignment, executed it flawlessly and were genuinely enjoyable to work with.
I will 100% work with Gateway for our next project.

Our experience with Charles Wah and Gateway Group has been nothing short of life-changing. When we started looking for a home, the dream of homeownership felt out of reach. Thanks to his incredibly supportive rent-to-own program, we were … More given a clear and manageable path to a place of our own.
What truly set Gateway Group apart was their amazing character and genuine care. They weren’t just a landlord; Charles Wah was a mentor who patiently guided us through every step of the process. He created a program that was fair, transparent, and built on trust. Without his help, we would never have been able to make this a reality.
We are so grateful for this opportunity and the immense support we received. Charles Wah and Gateway Group helped us build a future we didn't think was possible. We highly recommend him and his program to anyone looking for a truly caring and honest partner in their journey toward homeownership.
