The closest thing you can get to the great outdoors without stepping a foot outside is by adding a sunroom onto your home. A sunroom can give you an excellent view of the outdoors any day of the year, and is especially beneficial for homeowners in Sarnia, where the city offers breathtaking views of historic buildings, greenery, and the canal. If you are looking for the best sunroom construction services in Sarnia, look no further. At Carosyl Home Additions Inc., we are a general contracting company, offering sunroom additions to homeowners in our region. Sunrooms rank high among the most popular types of room additions, and can be that extra room your house needs to make it feel like a home.

Sunroom Additions with Carosyl Home Additions Inc.

Since sunrooms are engineered with floor- to ceiling-height windows, they are typically used as a conservatory or garden room. However, in more recent years, they are becoming more and more multifunctional; built with the purpose of being used as a family room, reading room, and breakfast nook. Whether you are looking for a space to put your green thumb to good use or an additional living space for your growing family, we can help. We are extremely skilled at matching new architecture with existing structures and will work with you to carry out your vision.

Discuss Your Sunroom Vision with Our Experts

Sunrooms are typically characterized as rooms that integrate the indoors and outdoors through glass walls and natural light. At Carosyl Home Additions Inc., our sunrooms can be designed and built in a myriad of ways to fit your style, budget, and vision.

Our goal is to bring your vision to life. We do so by discussing your goals for the project during a consultation.

The consultation will allow us to survey the style of your property and the proposed site, and to discuss your goals and ideal materials. We will then draw up a blueprint and provide an estimate for the cost of the construction.

Energy-Efficient Sunroom Designs

At our company, we work with your long-term interests in mind. That means when we sit down to develop your new sunroom, we carefully consider your future maintenance expenses and seek out ways to reduce them at every turn. To save you money both now and down the road, we utilize high-performance, energy-efficient products, and installation strategies. With intelligent electrical design and high-quality wiring and fixtures, we’ll turn your sunroom into an energy-saving machine. Month after month, you’ll see the results of our energy-conscious design work reflected on your utility bill.

Use more sun. Use less energy. Find out how with our expert sunroom contractors by your side.

Enjoy the Outdoors Year-Round with a Sunroom

Sunrooms are especially beneficial in a climate like ours. A sunroom will allow you to enjoy the outdoors, even when it's freezing cold outside. If enjoying winter weather sounds like a fantasy to you, you’ll be interested to know that our contractors source high-quality, patented glass that will allow you to use your sunroom 365 days a year. That’s right, in winter and summer, you can fill your indoor space with natural light. If you plan to use your sunroom extensively in the winter, we can also consider additional heating options at the point of construction. This will allow you to enjoy your space in complete comfort year-round.

What You Can Expect from the Sunroom Building Process

Constructing a sunroom is a complex process, but with the help of the right experts, it can feel easy! Our experts have worked in this industry for a long time. We have developed a building process that is efficient and gets the job done on schedule every time. Here's what you can expect from our sunroom building process.


Typically completed during the consultation, taking measurements of your space will allow us to determine what materials will be needed to manufacture your sunroom. We can complete the measurement process at any time that's convenient for you.


We will ensure that the construction plan meets all local zoning laws and building requirements. Our experts will help you obtain a building permit and ensure the plans are in appliance within local guidelines. Once the license is obtained, the building process can commence.


From laying the initial concrete to adding flooring, windows, and roofing, the construction can take as little as 1-2 days to complete.

Our builders specialize in sunrooms, and we work efficiently while paying close attention to every detail, to ensure that your construction meets our rigorous standards.


Once the construction is completed, we will walk you through your new addition, and ensure that you are completely satisfied before we bring the project to a close.


While your sunroom does not require much maintenance, don't be afraid to keep it clean by spraying water on the roof, windows, and exterior. You can clean the interior windows and ledges with mild soap and water to keep them looking their best.

Like all roofs and gutters, your sunroom should be inspected by a professional annually.

Fast Sunroom Construction

You can turn your sunroom ideas into reality much faster than you might think—at least, you can when you partner with our sunroom specialists. As meticulous, organized, and efficient tradespeople, we never let a moment go to waste, especially if it means you could be enjoying your sunroom a moment sooner. From your first consultation with us, we’ll map out every phase of construction to a tee to ensure a seamless building process and a fast-overall turnaround. We’ll assign a project supervisor to the case to oversee all aspects of the addition. Your supervisor will be your reliable point of reference from beginning to end. You can depend on us to build your sunroom from the ground up according to the timeline we laid out from the outset.

By the way, you can rest assured knowing our contractors place great emphasis on sound, compliant working practices.
