Frontiers Design Build - Guelph, Ontario

Frontiers is a wonderful company to deal with. We have hired them 3 times to do work for us and each time they have done an exceptional job. They renovated both of our upstairs bathrooms and most recently they renovated the entire main floor of our house. This was a major undertaking and required removal of support walls and installation of steel beams. We are extremely happy with the end result. Their quality and workmanship are second to none and I would not hesitate to hire them (I've already done it 3 times) or recommend them again.

I recently hired Frontiers Design Build Inc. to renovate a nearly 200-year-old farmhouse into a Net Zero-Ready duplex, and I am beyond impressed with their work. From start to finish, their professionalism and organization were evident in every aspect of the project.

Communication was seamless throughout the renovation. The team consistently kept me updated and ensured transparency in all decisions and processes. Their remarkable attention to detail demonstrated their deep knowledge of Passive House, Net Zero, and high-performance construction expertise.

One of Frontiers Design Build Inc.'s standout qualities is its network of professional consultants and trade partners who have brought a similar dedication to the project. The job site was always clean and safe, reflecting Frontiers' commitment to creating a secure environment for both workers and residents.

Their focus on sustainability was another highlight, aligning perfectly with the goal of making the farmhouse a certified Net Zero-Ready renovation. The team's impressive knowledge and execution of deep energy retrofits made them an ideal choice for anyone looking to undertake major renovations with a focus on energy efficiency.

I would highly recommend Frontiers Design Build Inc. for any major renovations or deep energy retrofit projects. Their professionalism, expertise, and commitment to sustainability make them a top-choice design-build contractor in the Guelph area.

We hired James and his crew to complete our full home renovation - and we are extremely happy! The quality of their work is exceptional. The project started with 3D drawings that made it so much easier to see the changes that we were making. James listened to our ideas but also incorporated some of his own suggestions to make our project perfect! We moved out of our home to complete this 6 month renovation. We were able to move back home on the exact day that was promised - no delays at all. During the renovation, communication was outstanding. We would meet with James on a weekly basis but also received texts, emails and calls to make sure that we knew exactly what would be completed. His team is amazing - every person he has working in your home will be polite, hard working and great at what they do! The job site is immaculate at the end of every day. We will use Frontiers for any future project - and recommend them to anyone we know. Thank you James and Frontiers for making our home so beautiful.

We hired Frontiers as our general contractor for a major renovation project that began in 2024 and continued into 2025. Like many homeowners, we were anxious about falling into a “renovation gone wrong” scenario with unreliable contractors—but our experience couldn’t have been more positive.
James and the entire Frontiers team were incredible to work with. They were not only knowledgeable, but also consistently responsive, accountable, engaged, professional, and personable. A project of this scale naturally comes with its share of stress and challenges, but the Frontiers team met every setback with open communication, clear goals, and the confidence to have the tough conversations when necessary.
A special shout-out to Luke, our project leader—he was fantastic. He kept us in the loop throughout the process and showed incredible patience during the moments when we felt overwhelmed or unsure.
The CoConstruct app was another highlight—it helped us track every detail, from plans and decisions to changes, finances, and communication. It made the entire process more transparent and manageable.
The Frontiers team truly excels at what they do, and they delivered on every promise. If we take on another project in the future, there’s no one else we’d trust to lead it

The people at Frontiers are great! We had the team do a renovation of our 1880s home, which included the addition of approximately 300 square feet, waterproofing the basement, tearing everything back to the exterior walls and re-insulating, all new windows and doors, opening up the main floor and a whole new floor plan on both levels, a new air source heat pump system, not to mention landscaping. We are amazed by the results. We were able to reduce our GHG emissions drastically, and our home is so much more comfortable than ever before.
We couldn't be happier!

Last summer, we enlisted the help of Frontiers Design & Build to give our backyard a complete overhaul and we couldn't be more thrilled with the results! The team at Frontiers, led by the talented and experienced Doug Taylor, truly exceeded our expectations and transformed our outdoor space into a luxurious oasis.

One of the standout features of the redesign is the stunning covered patio. It's the perfect spot for entertaining guests or relaxing with family and friends. The covered patio allow us to watch Blue Jays baseball games on a new outdoor TV and enjoy the game even on rainy days. The attention to detail is evident in every aspect of the design, from the high-quality materials used to the expert craftsmanship.

We are beyond impressed with the work that Frontiers did, and we can't wait to spend countless hours enjoying our beautiful new backyard. We highly recommend them to anyone looking to transform their outdoor space.

Frontiers Landscape exceeded our expectations on all fronts. We were blown away by their skill and quality of work. Their design was directly in line with our vision for our outdoor space. They were a pleasure to work with and have extraordinary customer service. We initially hired Frontiers to build a back deck. We were so impressed with the finished product that we've since hired them to complete our front driveway, front porch and they'll be coming back next spring to finish our backyard! We've referred them to friends, clients and neighbours! Frontiers Landscape are high quality professionals on every level.

We were having problems with our pool and were being told by a number of contractors we would have to wait a year or two to have it fixed. In addition, our backyard covered deck/porch was in need of repair. I again tried to find someone to help but could not get anyone to respond. We met with James and Doug in the fall and were told they would have the pool/patio rebuilt and a new covered porch designed and constructed by the following July. We first agreed to have plans drawn up before agreeing to start. We were thrilled with the professionalism and creativity of their team. The Frontiers team re-envisioned our patio and pool area and designed a vaulted timber frame addition to the back of our home complete with a wood-burning fireplace, retractable vertical screens, and an outdoor kitchen. We happily proceeded with the construction. They met all of their deadlines and produced a better product than we had anticipated. We had a few changes for them during the process which they easily accommodated. The communication process, both in terms of construction schedule and budget, was excellent. There were no surprises. I have recommended them to several of my friends and will continue to do so. Completely happy.
