What is a four season sunroom?

A four season sunroom is a kind of sunroom addition that’s custom-designed and insulated in such a way that it heats and cools all-year-round as per your convenience. No matter if it’s chilly outside or scorching hot, you and your family can enjoy the room comfortably every season of the year.

Typically, it has high performing energy efficient glass windows throughout the room. The superior insulated glass helps reduce the loss of heat in the winters and prevents heat and ultraviolet rays from entering during summers.

This fully enclosed and climate-controlled patio room is built almost entirely of glass. As a result, you get ample sunshine and a view of the outdoors — making your four season sunroom one of the most comfortable and scenic rooms in your house.

What’s more, there is additional insulation in the walls, roof, and floor to help keep the heat in during winters. You can also install an HVAC unit for either heating or cooling purposes.

Sunroom cost factors

There are various factors that affect the total cost to install a four season sunroom. This includes your sunroom design, roof type, where your new structure will be, additional sunroom features, your location, etc. 

For instance, if you live in an area that gets a lot of snow, your sunroom will need additional insulation and possibly a different structural design. Do check your local building codes and prescribed sunroom requirements. Getting a building permit will cost you anything between $400 and $2, 000. 

Let’s explore some of the cost factors. 

Sunroom placement: patio or deck

You can always build your sunroom onto an existing patio. It will save you considerable dollars. But, if you’re contemplating building a deck, you should be prepared to shell out $4,400 – $11,000. You may also need to consider the cost of constructing a concrete slab at an additional cost.

Site preparation

If you have to clear a part of your land and prepare it for construction, it will cost you between $1,400 and $4,400. Add to that a landscaping cost of $1,500 to $5,500. You may also need to factor in an excavation in case there’s a tree or a structure that you need to remove. That will be an additional $1,400 to $4, 800.

Size of the four season sunroom

A lot of your home renovation costs will depend on the size of your project. Since licensed contractors work by the hour, an increase in the size of your sunroom will mean an increase in labor costs. The cost to install a sunroom will range from $4,000 (for an 8’x10’ sunroom) to $20,000 (for a 12’x20’ sunroom).

Insulation

Since a four-season sunroom requires effective insulation to maintain reasonable heating and cooling, you must be prepared to shell out a minimum of $1,000.

Roof type

Typically, roofing costs anything between $2,000 and $8,000. Of course, the amount depends on your structure, its size, and roofing material. It’s the choice of glass that makes a difference in your four-season room cost. Also, whether you select an all-glass roof or a framed roof with skylights — will have a bearing on the total expense. 

Windows and doors

Window installation will amount to around $15,000 for a fully insulated solarium. Casement windows with low-E, laminated, or tempered glazed glass and screens will be approximately $2500 for materials and $250 for labor. 

In a four season sunroom, a door is not compulsory but you can always install one if you want to make the transition between the indoors and outdoors more natural. A sliding glass door will range from $1,000 to $2,800. There are also other expensive door options such as French, telescoping, or folding doors.

Electricity

If you’re going to be watching TV in your sunroom, you will have to install electrical wiring. Needless to say, your cost will increase if you require an additional electrical panel box. You can hire a licensed electrician for $160 to $500 (at the rate of $50 to $100 per hour) and get the work done seamlessly.

Here are a few potential electrical additions for your sunroom:

• Power outlet: $130 to $280
• Ceiling fan: $150 to $360
• Lighting fixture: $145 – $800

HVAC system

Adding heating and air conditioning in your sunroom will be between $300 and $6,000. In case you need to expand your existing ductwork, it will cost you in the range of $4,000 to $6,000 including installation. 

Labor costs

If you are constructing a four-season room on-site, this will mean hiring multiple contractors.

The average labor cost may vary based on location, the complexity of work, and the level of expertise. Having said that, here is an approximate price range for the various contractors:

• Carpenter: $40 to $80 per hour
• Electrician: $50 to $100 per hour
• Painter: $20 to $40 per hour

Interior finishing

Your sunroom’s interior design and decor will cost you between $900 and $3,000. Add to it the cost of painting ($800 to $3,000), flooring ($1,600 to $4,500), and sunroom furniture.
