If you’re thinking about a full home renovation in Thornhill, you’ve probably heard some scary construction horror stories ranging from projects dragging on for months to unexpected surprises and budget creeps.
That’s exactly why we built Sosna the way we did. Our process is designed to take the stress out of renovating, with clear communication, a well-structured plan, and a commitment to delivering a beautiful, functional home to you both on time and on budget.
After decades of refining how we work, we’ve created a system that lets you enjoy the process almost as much as the finished space. So, whether your home feels dated, doesn’t flow the way you’d like, or just doesn’t fit your family anymore, our step-by-step approach can help you fall in love with it again.
Whether your home feels dated, dysfunctional, or simply too small, here’s how our signature step-by-step renovation process can transform your space and your lifestyle.

Step 1: Initial Phone Call
Every successful project starts with a conversation. We like to start by getting to know you and what you need, what challenges you’re facing, and what you’d love to achieve. It’s our chance to listen, see if we’re the right fit, and explain how we work so you know exactly what to expect.
Step 2: Discovery Meeting
Next comes the in-home Discovery Meeting where together, we will explore your current space, discuss what’s not working, and discuss possibilities. We gather measurements, photos, and details that help us assess the scope of your renovation.
This is where your vision starts to take shape as a plan. You’ll meet our design and estimating team and start bringing your vision for your Thornhill home to life.
Step 3: Optional Feasibility Study
For bigger or more complex projects, we may suggest starting with a Feasibility Study, which will include concept drawings and a sense of preliminary pricing. This allows you to see a realistic idea of the possibilities for both your budget and your space.
Many of our Thornhill clients appreciate this step because it helps them make informed decisions early on before making a major investment decision.

Step 4: Design Phase
Our design process is famously detailed. Our team is all in house, and includes interior designers, engineers, and estimators. They will work closely with you to refine every aspect of your renovation. From layout and functionality to finishes and materials, every detail is meticulously planned.
Your renovated home should feel beautiful, functional, and tailored to your everyday life.
Step 5: Quote and Signed Agreement
With the design complete, we provide a highly detailed fixed-price quote. Once the agreement is signed, your renovation is officially scheduled.
We’re known as planning rockstars for a reason! Every minute of construction is planned before a hammer hits a nail.
Step 6: Pre-Construction Meeting
Before construction begins, we host a Pre-Construction Meeting in your home with your dedicated Project Supervisor, who will manage your project from beginning to end, and will be there every step of the way to ensure your renovation runs seamlessly, and with full communication to you.
They’ll walk you through the timeline, introduce you to your renovation team, and review all the logistics so you know exactly what to expect.
Step 7: Construction Phase
With Sosna, you don’t have to juggle designers, contractors, or engineers. We handle everything under one roof from start to finish, with careful oversight and daily quality control logs.
Your dedicated supervisor ensures every step is executed to perfection and communicates with you regularly. Most of our Thornhill clients say the peace of mind knowing their renovation is in good hands is one of their favourite parts about working with us.
Step 8: Pre-Delivery Inspection
The pre-delivery inspection gives us a final opportunity to address any lingering issues before your home is revealed.
Using our detailed checklist system, we ensure nothing is overlooked, and your finished home is exactly as you imagined, right down to the smallest details.
Step 9: Final Walk-Through
We then do a walk through your home with you one last time. It’s a chance to celebrate together, take in the results, ask any questions, and picture yourself enjoying your new space!
Step 10: Warranty and Ongoing Support
Our relationship doesn’t end when we hand you the keys. You’re a part of the Sosna family now! That means you get access to our exclusive handyman service for any future needs! And of course, peace of mind with our warranty.
We’re proud to offer long-term support for every renovation we complete, which is why so many of our Thornhill clients refer their friends and family to us.
