RenoNerd are Saskatoon’s innovators of renovation. We combine decades of experience with cutting-edge technology to provide you with the products and styles that are perfect for you.

For many years, we worked under the banner of St. John Windows and Doors, focusing mainly on these two products. Our aim was to provide superior service along with the best products to fit people’s budget – while also adding beauty and originality whenever possible. Our clients frequently praised us for high-quality work and asked us to expand our services. Soon, we were installing siding, building decks, and performing elaborate home renovations – and we loved it! RenoNerd’s nerdlings truly are Saskatoon’s premiere windows and doors experts, and we have the know-how and passion to help you realize all your renovation dreams.
And this is where our nerd vibe really runs wild. We love working with people who want something unique and personal. At RenoNerd, we pride ourselves on our creativity and craftsmanship. We enjoy suggesting innovations to clients and appreciate when clients ask questions and share their visions with us. After taking the time to learn what you want and need, RenoNerd turns to our innovative technology to showcase a wide variety of options you may select. Having said that, we never offer you selections that we wouldn’t install in our own homes. We do our best to provide different price points; but all the products we offer are the best in their class. We refuse to compromise in the quality of the products we sell or in the quality of our workmanship.

Why Choose Us?


As local nerds, we know how hot Saskatoon’s summers can be and how frigid our winters often are. As such, we realize the expectations you have of your home and are very knowledgeable of the products you need to keep the cold out in the winter and the hot out in the summer. Next, we may try to figure out how to bottle up that summer heat to bring it out in January,


Although many people say we look youthful and handsome, we really do have over two decades of experience in the industry. RenoNerd’s original partner, Director of Creativity Chad St. John, owned and operated St. John Windows and Doors for many years, starting from scratch to develop it into a prosperous enterprise. Just as he was thinking of expanding, his old chum Dorian Klingenberg (who prefers to be known as the Grand Poobah) approached him about bringing his decades of computer geekdom into the mix. So far, the intermingling of craftsmanship and technology has been a resounding success! RenoNerd continues to thrive in the various ongoing relationships we have established with customers and leaders in the manufacturing industry while also forging forward to develop new relationships.


We are more than just a window company or a renovation company. RenoNerd has developed new tools, technologies and processes that put us at the forefront of the entire industry. We use these technologies to swiftly and seamlessly provide our clients with diverse options for their renovations. Naturally, being good corporate and community citizens, we share our knowledge with our partners and competitors alike to help us all improve.


Being nerds, our brains sometime work faster than our mouths can speak, but we always make sure to fully explain our vision to our clients, pointing out any potential complications that may arise, and answering any questions you may have. We want you to be happy with the products we install. To quote our Director of Creativity, “I won’t see it from my home; so I want you to be 100% happy and satisfied with what we’re installing.”


Whether your house was built a hundred years ago or a hundred days ago, there’s a chance that you’re not satisfied with the style or efficiency of some of your products. We have a wide array of energy-efficient products, including windows and doors, that will save you money in the long run and also help you do your part for our planet.


In the 1980s, everyone knew that Remington Steele’s word was hid bond. In 2020, ditto for RenoNerd! We assure you that you will be satisfied with our work, and our long line of happy customers can attest to that.
From the time you contact us, we make sure you understand all of your options and we guide you to select the product configuration that's right for you. We use the best practices to install products to ensure that they meet the industry’s highest standards. This is important because some companies (and we won’t name names!) do not adhere to these standards, whether due to time constraints, a lack of knowledge, or because they mistakenly deem them unnecessary. Months or years down the road, when you may no longer remember who you hired, you may run into issues and find that your warranty has been voided. This will never happen with RenoNerd. Allow us to stand on our soapbox for a moment: We pledge to stay up to date on the most current industry standards and make sure those standards are followed from start to finish! This will ensure your warranty remains valid. Once your renovation is completed, our Director of Creativity will provide a final quality inspection and ensure you are completely satisfied.


If it wasn’t clear from the above, we will put our guarantee in writing one more time: our work will not void your warranty. In the off chance of some manufacturer’s defect, our service technicians are trained by our manufacturers and they are fully qualified to provide warranty service on the products they have installed. That gives you peace of mind now and peace of mind for your future self too.
