When planning to invest in your home with a sunroom addition, timing is everything. Many Ontario homeowners ask, “When is the best time to buy a sunroom?” The answer might surprise you — Fall is actually the ideal time to start planning and ordering your sunroom in Southwestern Ontario with Four Seasons Sunrooms & Additions.
Why Planning Ahead Makes a Difference
Investing in a sunroom addition from Four Seasons Sunrooms requires careful planning to bring your vision to life. Unlike buying a car or a boat, a sunroom project involves several important steps before installation can begin, including design, engineering, permitting, and manufacturing.
The first step is the initial design, prepared by your design consultant. This helps you visualize every detail, including:
-
- The size and style of your sunroom
- Available options and features
- Construction materials
- How the new space will connect to your home
Along with the design, you’ll receive a scope of work, outlining a detailed breakdown of what’s included in your sunroom project and the total investment required.
From Design to Detailed Drawings
Once your order is placed, it moves into the production department. Precise site measurements are taken — accurate to an eighth of an inch — to ensure your architectural drawings are exact.
Our production team then creates architectural drawings with detailed construction specifications. These drawings are used both for building department review and to guide the installation team on-site.
This process typically takes 6–8 weeks, depending on the complexity of your project.
Client Review and Engineering Approval
After the architectural drawings are complete, you’ll have the chance to review and approve them. During this stage, we go through the plans with you in detail and answer any remaining questions.
This is your final opportunity to make major changes before the drawings are sent to a structural engineer for review and approval. Once the engineer stamps the plans, your sunroom addition is ready for the building permit submission.
Building Permits and Approvals in Southwestern Ontario
The building permit process varies by municipality but generally takes 4–8 weeks. In some cases, additional requirements — such as minor variance applications or conservation authority approvals — may extend the timeline slightly.
Once your permit is issued, your project moves forward to the material ordering stage.
Manufacturing and Installation Timeline
Once your building permit is approved, we order all the materials needed for your sunroom. Material delivery typically takes 6–8 weeks. After everything arrives, we schedule your installation, usually within 2–4 weeks.
At that point, one of our expert installation crews will arrive on-site to begin construction. Most sunroom installations take about 3–4 weeks to complete, depending on the design and scope of the project.
The Full Timeline — And Why Fall Is the Perfect Time for Your Sunroom
From the moment you place your order to the day you’re enjoying your new sunroom, the entire process typically takes 6–8 months. Timelines can vary depending on project complexity, complexity of your design, permit approvals, and seasonal factors.
This is why fall is the perfect time to start your new sunroom project. By planning and placing your order between September and November, all design, engineering, and permit steps can be completed over the winter months. When spring and summer arrive, you’ll be at the top of the installation schedule — ready to enjoy your new sunroom sooner!
