For more standard sunrooms—that is, ones that are fully enclosed with glass, screen, or a combination—Forbes Advisor offers a wide range, citing as little as $10,000, all the way up to $80,000 or more, with most living between $25,000 and $45,000. One of the big things that determines the cost is how insulated the sunroom is.
Insulation takes many forms, each of which can affect the sunroom price. A sunroom made of wood and drywall may have insulation built into the walls. An all-glass room like a solarium may feature gas filled windows and an extra thick glass roof to provide some level of insulation from the weather inside.
One thing to keep in mind is that contractors usually charge by the square foot, by the hour or by the job. Sunroom square footage and extra features can have a big influence on the cost of the sunroom, because the cost of materials goes up with the size of the room.
Factors that will influence the cost of a sunroom addition include:
Framing materials: Aluminum and plastic tend to be the least expensive type of framing available. Higher end sunrooms are usually constructed of vinyl or wood.
Window type and feature: Sunroom glass windows range from single pane to gas-filled, double pane. Large sunrooms can include many windows, which can increase the prices dramatically. Installing vinyl sunroom windows can provide a nice balance of energy efficiency and cost savings.
Electrician: Electricians usually charge an hourly rate between $50 and $100. You only need an electrician if you want your sunroom to have power. This is not usually the case for solariums and conservatories, which are made entirely of glass. Sunrooms that feature roof panels often include a fan and electric light.
HVAC costs: Some full-scale sunrooms will involve a connection to the home's HVAC system. These contractors can charge by the hour or by the job, depending on the work that needs to be done.
Flooring costs: High-end and four-season sunrooms may have attractive flooring options like tiles or carpeting. Flooring contractors charge by the square foot. Tile installation costs between $11 and $17 per square foot, while carpeting usually costs between $4 and $6 per square foot.
We’ve been using the term sunroom rather generally to talk about costs. But in reality, there are many differences in the type and style of sunroom you choose that will affect the budget. Three-season sunrooms are less expensive than all-season sunrooms. But at Champion, we pride ourselves on working with homeowners to find a solution that meets their budget.
